Prompted by curiosity, or animated by a thirst for knowledge, it is ever anxious to extend its researches beyond the boundaries which it has attained, and to acquire new ideas. Such being the constitution of the human mind, the exertion of its powers to the utmost of their ability, in obtaining knowledge, is highly commendable. But as the happiness of man depends | on the nature of his acquirements, and as the correct- ness of his morals will be in proportion to the ac- curacy of his principles, nothing can be more obvious than that it is of the utmost moment his attention should be directed to proper objects of contemplation ; and that the operations of his mind should be under the control of an accurate judgment. An error here may lead to results beyond description calamitous, 1s, PREFACE. All the objects which invite our attention are either of human or of divine origin; and they bear upon them characteristics which determine their author. I would not be supposed to depreciate human science, or disparage those surprising efforts of the mind, which various pieces of mechanism demon- strate: but, granting to the efforts of created intellect all the admiration which they can justly claim, will they, for one moment, bear a comparison with the productions of Deity? The highest efforts of human ingenuity sink into insignificance when viewed in comparison with the least of the works of God. Created intellect is narrow in its resources. Our Inventive career is soon exhausted, or speedily im- peded by insurmountable obstacles ; and imperfection is discoverable in every thing which the mind of man originates, and which his hands execute. The most complete work which is the offspring of his skill has its blemishes. But these imperfections are not discover- able in the works of a divine agency; the lowest efforts of his creative power contain a perfection of structure, and a complication of parts, which astonish the greatest human intellect, while existing facts clearly demon- strate that his resources are infinite. In his works there is an undefinable variety to amuse, almighty power to surprise, exhaustless goodness to engage, and unbounded wisdom to delight, every attentive beholder. If the works of God so infinitely surpass those of man, it follows, that a knowledge of the former PREFACE. iil must, in the same proportion, exceed in importance that of the latter. Every new attainment here tends to enrich the mind for eternity, while it yields an ample compensation in the present state for the labour of acquiring it. And never are the powers of the soul so rationally, and so nobly employed, as when their utmost energy is engaged in pursuits so truly sub- lime. That man is in a state at once most criminal and most pitiable, who can pass along the journey of life which leads him through a universe of wonders, all of which discover that gracious Being to whom they are intended to conduct him, and yet neither admire his works, nor love their author. Objects which will engage the attention, and excite the admiration of angels, and of the spirits of just men made perfect to an unceasing e¢ernity, surely cannot be unworthy of the investigation of intellectual beings during the period of their probation in ¢zme. The volume of inspiration constantly appeals to the facts of nature*in order to illustrate the perfections of deity, and to explain spiritual and moral truths to the human mind; while the objects of nature lend their willing aid, and surprisingly well perform the important services required. It has therefore been a matter of great astonishment, that natural philo- sophy and scripture theology should ever have been considered as opponents, and as supporting contrary interests. What do the Sacred Scriptures design but to instruct us in those things which relate to iv | PREFACE, God? And does not nature teach the same? Does not he who was pre-eminently a teacher sent from God, sanctify philosophy by employing its various objects in order to convey divine truth in the most comprehensible form to the human mind? This mode of instruction was so general with him, that it is remarked,—“ Without a parable spake he not unto them.” And his parables, in general, were founded on the facts of nature, and spoken with all the accu- racy which a perfect acquaintance with the philosophy of those facts could furnish. Philosophy is so blended with the religion of the Sacred Scriptures by the spirit of inspiration, that an attempt to separate them would do violence to arrange- ments which have been made by infinite intelligence. This union indeed is so intimate, that many portions of divine revelation cannot be understood without a knowledge of nature; and the excellency and sub- limity of other passages, cannot be discovered without some acquaintance with nature as‘well in its causes as in its effects. That theologian is therefore qualified to be an able expositor of the volume of inspiration, in whom are united a renovated heart, and a sound philosophy. Possessed of an under- standing illuminated by the spirit of God, he will so employ the objects of creative power, as to display the truths of revelation to advantage, and conduct the mind “ from Nature up to Nature’s God.” PREFACE. : Vv There is a philosophy, indeed, but “it is falsely so called,” which is inimical to revelation, and de- structive of its grand peculiarities. Of this we cannot be too cautious. It is the ally and the slave of infidelity ; and is composed of elements gathered from the regions of an universal skepticism. It is pom- pously arrayed in words of human vanity, and under fair pretences deludes the unwary, while it fascinates and delights the depraved heart. It designs to serve a cause which is hostile to truth and human happi- ness, and robs true science of a title to which it has no legitimate claim, by which to aid its operations. But shall Christians abandon the thing, because infi- delity has abused its name ? While philosophy aids our conceptions of the truths of revelation, and is in perfect unison with them so far as nature can accompany revelation ;— for even the present advanced state of science has not demonstrated the smallest discrepance between them :—yet, as the latter is intended to teach us what is not to be known from the former, we must expect revelation to contain what cannot be comprehended by philosophy or reason.. This is the fact. And under this view of things, what can be more absurd than to reject the truths of revelation because they cannot be explained by the rules of philosophy? or to discard the aids of philosophy because it cannot unravel the mysteries of revelation? Nature and revelation are two volumes written by the same hand ; vi PREFACE. and each develops truths agreeable to the design of the great Author, and accordant with the necessities of the human race. Many, whose sentiments are hostile to the grand peculiarities of Christianity, ave arrogated to them- selves the dignified title of philosophers ; and in the most presumptuous and insolent manner, have insulted and assailed those sacred truths of which they were totally ignorant ; and endeavoured, with all the arts of an infernal agency, to hold up religion, and those who have professed it, to contempt and insult, while they propagated sentiments which tend to dissolve all the bonds of social order. In senti- ment they are infidels; and in practice, atheists. Not distinguishing between real philosophy and the wicked designs which some propose to accomplish by as- suming the title of philosophers, many pious persons have imagined that philosophy tends to skepticism, infidelity, and atheism. This supposition 1s_per- fectly groundless and illegitimate. ‘True philosophy is the friend of Christianity, and solicits to be her associate and companion. They serve no jarring interests ; they proceed in parallel courses, and aim to advance the same ulterior object, which is—the clorifying of God. The Author of this volume has long thought a work of this nature a desideratum in the religious world, not only to correct the evil just named, but to meet that thirst for information on these topics PREFACE. vil which has been excited, especially among young persons of respectability. The books which have ‘been published on similar subjects are encumbered with so much superfluous matter, exploded phi- losophy, and abstruse and uninteresting metaphysics, as to render them unsuitable to the present day. The writer has endeavoured to introduce into his work such facts and principles as he thought would, at the same time, interest the understandings, and_ benefit the hearts of his readers. As he treats of positive FACTS, and not uncertain spECULATIONS, he did not deem a splendid or pompous style necessary or suitable; but has aimed at a plain and lucid diction, as that which he conceived the most becoming the nature of his subject. Where he could, he has avoided technical phraseology ; and excepting proper names, which to some may have the appearance of it, the Reader will find but few words which are not commonly understood. Whatever we discover in the works of God WHICH IS ADAPTED TO CERTAIN ENDS, we ascribe to that glorious attribute of his nature which we call Wispom. In this sense the term wisdom is em- ployed through this volume, which proposes to con- centrate information illustrative of Divine Wisdom, gathered from the vast and interesting regions of Creation, Providence, and Redemption. The Author supposes that those, in general, into whose hands this effort of his pen is likely to fall, are better acquainted vill | PREFACE. with the subjects discussed in the two last Essays, than with that treated of in the first:—this will ac- count for the disproportjon which will be seen in their length. The Author can assure the Reader that it is with great diffidence he appears before the Public in this volume: however, he feels encouragement from a con- sciousness of the best intentions. ‘The great variety of subjects discussed, and his distance from the press, he hopes, will apologise for any errors, either of subject or of typography, which may have escaped his notice. Public or private criticism he will receive with thankfulness, from the hope, that a second edition of the work, should it be destined to this honour, will obtain from it essential advan- tages.

But a small part of his design was accomplished when he had given being to the materials of which it is composed. The power which he exerted was under the direction of that Wisdom which meets every purpose with adequate means for its completion. ‘The quantity of matter created, the diversity of its essential properties, their order and proportions, and the general modification of the whole, were perfectly adjusted to those future ar- rangements which he had determined to give them. The general form given to this vast mass of ma- terials, is the first thing to be noticed. It was to be such as to allow of changing seasons, a diurnal re-" volution, and the ebbing and flowing of tides. Every possible shape was within the power of Omnipotence, and one as easy of accomplishment as another ;—- but which of these forms is the most suitable to the 6 INORGANIC MATTER. FORM OF THE EARTH. purposes just mentioned? We can conceive of no one in all respects so fit as the globular. Every other would have been attended with obvious inconvenience. Had it been cubical, or an extended plane, or cylin- drical, or conical, or prismatic, or any other within the reach of our imagination, these essential results could not have taken place with equal order and facility. Now that such is really the form of the earth, is incontrovertible. For if a ship be sailing from a person placed on the shore, he first loses sight of her hull, then of her masts gradually from the lower parts, till she quite disappears. If, again, a ship set off in an easterly direction, she will circumnavigate the earth, and return by the west. . A lunar eclipse is occasioned by the shadow of the earth falling upon the disk of the moon; and that shadow always forms a dark circle, more or less perfect, in proportion to the extent of the eclipse. But these phenomena could not take place unless the earth were spherical. It is not indeed a regular globe, but an oblate spheroid; and its diameter at the poles is something less than at the equator. ‘The shape of the earth very much resembles that of an orange, its flatted sides corre- Sponding with the polar regions. An objection may be made to what has. been mentioned, and some difficulty may arise in the mind respecting the spherical shape of the earth, on account of thosé¢ vast mountains and deep vallies which INORGANIC MATTER. 7 | THE EFFECTS OF THE CENTRIFUGAL FORCE. a EN I eas abound in most countries. But when it is considered how small a proportion these bear to the whole superficies of a globe whose circumference is twenty- four thousand miles, it will be obvious that the highest mountains no more prevent its being spherical, than a few particles of sand sprinkled upon an artificial globe of twelve inches in diameter, would destroy its rotundity. The Matter, of which this globe is formed, was perhaps originally in a soft or pulpy state. Its ro- tatory motion on its own axis from west to east, which is extremely rapid, has generally been supposed to have occasioned this shape, as that motion would make the soft matter to rush towards the equator with a disposition to fly off by the centrifugal force. However, a modern writer on this subject has at- tempted to show that this earth was made ror such a motion, and not so shaped By it, in order that the water might be kept from accumulating at the polar regions, and be thrown towards the equator, as its presence there is essentially necessary. There is con- siderable force in this observation; and if true, it affords an additional discovery of divine wisdom and goodness, in the structure of the earth. However, I feel disposed to think that it received its present formation both By this motion, and in order to it. Admitting the accuracy of the Mosaic account of the Creation, we shall not dispute that the surface, at least, of this earth was in a soft state. And as it seems 8 INORGANIC MATTER. ; COMPONENT PARTS OF THE EARTH. | that its diurnal rotation on its own axis was then communicated to it, and as it will not be disputed by any who are acquainted with the natural effects of that motion, that an accumulation of matter would take place towards the equator, so it will follow that such a shape as I have mentioned would be the consequence. In the mean time that the more pon- derous materials of this globe were accumulating towards the equator, the water was retiring into its appointed channels. The earth acquiring a state of solidity, the process would gradually cease ; otherwise, such must have been its protuberance at the equator, that it would have assumed the shape of a circular superficies, whose polar diameter would have borne but a small proportion to its equatorial, and the consequence would have been an entire unfitness for the purposes of its creation; and hence a defect of wisdom in the great first cause would have been evident. Having mentioned the Shape of the earth, let us now consider the various Materials of which it is composed, . which affords a striking discovery of foresight and design. ‘These materials present a surprising diversity of substances, which, when com- bined with each other, and with all the varieties of their own species, constitute an almost infinite variety of substances ;—a variety so great, that chemistry, even in its present improved state, embraces probably but a small part of it. INORGANIC MATTER. 9 NUMBER OF ELEMENTARY BODIES. The Elementary Bodies, or those which are inca- pable of decomposition, at present known, are forty- seven. Of these, thirty-eight are metals; six are inflammable bodies; and three, substances which unite with metals and inflammable bodies, and form with them acids, alkalies, earths, or other analagous compounds. ‘The Chemical Elements acted upon by attractive powers, combine in different aggregates. In their simpler combinations, they produce various crystalline substances, distinguished by the regularity of their forms. In more complicated arrangements they constitute the varieties of. vegetable and animal substances, bear the higher character of organization, and are rendered subservient to the purposes of life. And by the influence of heat, light, and electrical - powers, there is a constant series of changes ;—matter assumes new forms; the destruction of one order of beings tends to the conservation of another; solution and consolidation, decay and renovation, are con- nected ; and whilst the parts of the system continue in a state of fluctuation and change, the order and’. harmony of the whole remain unalterable. * I shall consider the Inorganic Bodies belonging to the globe, as either Soxips or Fiuips. er een. - * Sir Humphry Davy’s Agricultural Chemistry. 10 INORGANIC MATTER. METALS.—MALLEABILITY OF GOLD. THE SOLID MATERIALS OF THIS GLOBE. Somenties. “otaemeeed Metats are simple bodies, characterized by their absolute opacity, great degree of gravity, pecu- liar brilliancy, and insolubility in water. Some of them possess a considerable degree of ductility, but this property is not common to them all. Almost all the metals seem to be capable of impressing the organs with a peculiar taste and smell’. Professor Davy mentions thirty-eight different sorts already known. All of these have different degrees of im- portance and usefulness in the grand economy. The uses of the more common metals are well known. They contribute to domestic convenience, agricultural improvement, and a variety of important purposes in the different arts of civilized society. Metals enter into the constitution of almost all other bodies; they are found in plants, stones, and even floating along the arteries and veins* of many animals. Of all the metals, gold is the most susceptible of malleability and ductility; and on these accounts, together with its not being liable to corrosion from ee a ee ° Parkinson. | * A small proportion of iron is found in the blood of some animals, and is supposed to be the cause of its red colour.

It has been calculated that it would take fourteen millions of films of gold, such as cover some fine gilt wire, to make up the thickness of one inch; whereas fourteen million leaves of common printing paper make up almost three quarters of a mile; and that one ounce of it is sufficient to gild a silver wire more than thirteen hundred miles in length. The Eartus which are known, are nine in number; of different qualities, characteristics, and uses. ‘Their essential properties, like the essential properties of all other substances of our globe, are but little known. It is from them principally that vegetables derive their stamina, and their grand sup- port. By being mixed together in different propor- tions, under different circumstances, a great variety of earths is produced, forming soils suited to the almost unbounded variety of vegetables which cover the surface of this globe, and which derive their respective nutriment from them. Lach class of vege- tables requires a composition of these earths, in some respects different from all others, that it may grow with vigour, and subserve the purposes of its original formation. Some vegetables require a soil of a more loose, others of a more compact consistence; and this variety of compositions is found upon the face of the globe, most exactly adapted to the necessities of vegetation. 12 INORGANIC MATTER. = THE LOADSTONE. ee ee Those masses of matter which we call STONES, are composed principally of the nine earths mixed together in different proportions and numbers. Some stones are nearly simple, formed by a concretion of one earth to the exclusion of almost all the rest 5 others are compounded of two, three, or all the earths, embracing also metals, salts, shells, and a number of other substances, constituting stones of different textures, solidity, and variety, almost innu-. merable. ‘Their uses in society are too well known to need description. There is one of. these substances, which, on account of its singular properties, and peculiar im- portance to mankind,. deserves to be mentioned ;—it is the Loapsrone. Though its application to the purposes of navigation is comparatively of recent date, Providence seems to have conferred on it ex- clusive properties, with an original regard to its ulterior appropriation. The fluid, or peculiar pro- perty of this stone, be it what it may, (for it has hitherto completely baffled the skill of the most acute philosopher to say what it is,) is capable of being communicated to a metallic needle, which, when balanced upon a pivot, directs one of its ends to the north pole. Aided by the magnetic needle, ships are navigated from one country to another the most remote, with an exactness and certainty which was thought impossible before this great discovery was made. The destruction of this fluid, or its sus- INORGANIC MATTER. 43 THE MATERIALS AND SOLIDITY OF THE EARTH DISCOVER WISDOM. pension, would occasion an almost entire interrup- tion of that intercourse which is carried on by the nations of the earth, so necessary to their mutual advantage. A variety of other substances might be mentioned under the class of solids, such as salts, sulphurs, and alkalies; but the design of this work forbids enlarge- ment on this part of our subject. And though, when we look upon these objects, they appear rude, shape- less, and uncouth; yet, when we analyse their parts, and develop their physical properties, we see that they possess the finest and most important qualities, —food for the most fragrant flowers, and the most delicious fruits. What foresight is here manifest on the part of the Deity, in regarding the necessities of plants and animals! and what wisdom appears in the formation of these objects, so suitable to their respec- tive ends !—Animals require vegetables, possessed of certain properties, for their nutriment ;—these vege- tables demand also their support from the soils in which they grow,—and these soils are endowed with all the requisite qualities. How evident the wisdom of that Being, who is wonderful in counsel, and mighty in executing ! These various materials, blended and brought into contiguity, form the dry land, which is destined to support animals and vegetables. The surface of the earth is so tempered with a due proportion of water, as to be neither so soft as to yield under the incum- 14 INORGANIC MATTER. MEANS OF THE EARTH’S DUE TEMPERATURE. bent pressure, nor so hard as to forbid the roots of plants from penetrating into its pores; and by this means at the same time acquiring firmness, and obtaining their food. The same unerring skill is apparent in the preserva- tion of the earth in a temperature suited to vegetation. Were the earth subject to as great a degree of cold as the atmosphere by which it is invested, the | vegetable creation would be destroyed by its inten- sity. But a most wise and merciful provision is made by the Creator against this, and to continue the earth in nearly the same temperature in even the coldest regions. When the atmosphere is reduced to thirty-two degrees, the water which is contained in it is congealed, descends in snow, and covers the earth. Snow being a bad conductor of heat, it refuses to carry off that which the earth contains ; so that the parts covered by the snow are but rarely reduced below the above temperature of thirty-two degrees, which most vegetables can bear without being destroyed. ene ene THE FLUIDS WHICH BELONG TO THIS GLOBE. Warer is the first of those fluid bodies I shall mention. It occupies nearly two-thirds of the sur- face of the globe, in oceans, seas, rivers, and lakes. INORGANIC MATTER. 15 THE COMPONENT PARTS OF WATER. And besides the surface which it covers, it is diffused over the earth by means of perforations and channels, which, like the arteries and veins of animals, carry this important element in all directions; and these lie so contiguous to each other, that a well of three or four feet in diameter can scarcely any where be sunk, but a vein is cut, and water springs up. Excepting a few degrees round the poles of the earth, which are not inhabited, it is found generally in a fluid state, and so remains until it is deprived of its caloric or fire, when it immediately becomes ice, and is then unfit for most of its invaluable pur- poses. In its fluid and useful state, it therefore con- tains a considerable quantity of heat, which it derives from the incumbent atmosphere, and which at once preserves it liquid, and contributes largely to the support and increase of organic bodies. Water was generally supposed formerly to be a simple uncompounded body ;_ but it is now determined by analysis to be a compound. I need here only give the opinion of an eminent chemist. “ Water,” says he, “is an uninflammable fluid, and when pure, is trans- parent, colourless, and void of taste and smell. It is formed by the union of hydrogen and oxygen (gas), and may be considered as an owvide of hydrogen; oxygen and hydrogen appearing to unite only in that certain proportion, of which water is the result*.” One « Parkinson. 16 INORGANIC MATTER. THE INFLUENCE OF OXYGEN, &c. ON VEGETATION. hundred parts of water are found to consist of eighty- five parts of oxygen, and fifteen of hydrogen gas‘°. An experiment has been made for the purpose of forming water by these gases. Nearly two hogsheads of hydrogen gas, weighing one thousand and thirty- nine grains; and about one hogshead of oxygen gas, weighing six thousand two hundred and ten grains; amounting together to seven thousand two hundred and forty-five grains, were used in this experiment, and the whole produced about three-fourths of a wine pint of pure water. Water, when decomposed, or reduced to its primary elements, yields these two gases.—Which of these substances was originally formed? Was the whole of the water on the face of this globe formed by the combination of these gases ; or were these gases formed by the decomposition of water? The one or the other of these suppositions is probably the fact. Either supposition gives us a most grand and overwhelming idea of the wisdom and power of the Creator. j A modern author raised a variety of vegetables, under circumstances where they could derive no nutriment from soil, and which were supplied with distilled water only. Afterwards he submitted them to a careful analysis, and each kind yielded products exactly the same as if they had been grown in soil; * Gregory’s Economy of Nature. INORGANIC MATTER. 17 WATER A PART OF NEARLY ALL SUBSTANCES. he concludes his account by remarking, that “Oxygen and hydrogen, with the assistance of solar light, appear to be the only elementary substances em- ployed in the constitution of the whole universe ; and nature, in her simple progress, works the most infinitely diversified effects by the slightest modifica- tion in the means she employs.”! The particles of matter of which water is com- posed, are extremely small, so that it enters into the pores of almost all other bodies with facility, affords support to animals and vegetables, and forms an important part of nearly all the substances of this globe. In the sea it is mixed with a considerable proportion of salt, to preserve it from a state of putre- faction. Diffused over the face of the earth, either by springs under its surface, or by rain from the atmo- sphere, it is found fresh, or freed from its saline particles. For as those particles are heavier and more gross than the water with which they are mixed, they are separated either by evaporation, by means of which the clouds are formed to supply the earth with rain, or by a filtration through the earth, when it enters into the subterranean aqueducts which supply us with springs. It is essentially necessary that it should be reduced to this state, in order to serve the purposes of animal nutriment, and sup- plying our domestic necessities, * Parkes. ¢ 18 INORGANIC MATTER. a aS THE USES OF WATER. 2 In addition to the above remarks on the pro- perties and. utility of this important fluid in the economy of nature, it may be remarked, that it forms an element which supports creatures innumerable, both small and great, from the monstrous whale to the animalcule, thousands of which float and play in a single drop; it links together the most distant nations, and affords the means of the freest inter- course amongst them; it softens the earth, and pre- serves it ina proper state for the wise purposes of its formation; and is subservient to innumerable other ends, which could not have been answered by it had it been formed on different principles, or under any other modification. Water brings the different soils into a proper state to perform their office. Dry earth of itself has little effect; but when moistened, it bas the property of decomposing atmospheric air, and of conveying its oxygen to the roots of those plants which vegetate within it.® | Had water been as solid as earth on the one hand, or as subtile as air on the other, it would have been utterly unfit for any of the important uses to which it is now appropriated, and for which it 1s most exactly adapted." ® See Parkes. " The following curious and interesting experiments were performed recently, during a voyage to Malta, which show the influence of the pressure of water on bodies at great depths.

Surrounding this terraqueous globe,. is an ATMo- SPHERE Of a most curious structure; and much more so than is generally known. Its constituent parts An empty bottle, closely corked, was let down about fifty fathoms. When it was drawn up, it was filled with water, the cork turned, the bottom end being uppermost, and forced nearly half way out of the bottle. A bottle was then filled with fresh water, corked closely, and let down. When it was drawn up, the cork was turned upside down, and the water was brackish. Next, a piece of twine was put under the cork, and tied round the neck of the empty bottle, so that if the cork were driven in, the twine must break. When it came up, the cork had been much forced, but had not given way, and the bottle was half full of water. A piece of twine was again put under the cork, the bottle having been emptied, and a thin coat of sealing-wax over the cork, This was sunk ninety-eight fathoms. When it was raised, the twine and sealing wax were both broken, the cork turned upside down, and the bottle full of water. Tn another experiment, a piece of twine was put under the cork as before, and a strong stocking needle was forced through the top of it, which rested on each side of the neck of the bottle; then it was dipped several times in boiling pitch. It was then let down to the depth of the last. When it was drawn up, the cork was again turned, the twine broken, the needle bent and pushed in with we cork, and the bottle full of water. In the last experiment, a cord was put cross-wise under the cork, so that the water had two folds to break. The cork and the bottle neck were dipped in boiling pitch; and afterwards, a piece of strong canvas was tied close over the warm pitch; then the canvas, cork, and. bottle neck, were dipped in pitch again. This was sunk ninety-eight fathoms, and it was found C2 to 20 INORGANIC MATTER. ‘ NATURE OF ATMOSPHERIC AIR. ——_— are so adjusted and so blended, as to form an economy altogether worthy of the wisdom by which it was devised, and the power by which it was effected.’ Atmospheric Arr is the next fluid I shall con- sider, and the next in density to that of water *. It is matter under an invisible form; its general properties are gravity, elasticity, and transparency. It may be compressed into a space much less, or rarefied to occupy a space much larger, than it naturally fills. It invests this globe to a considerable height, and accompanies it every where along its orbit round the sun. It is not a simple but a eom- pound body; and it is composed of three different See Baas to be water proof. The water had, made a powerful effort to force in the cork, twine, and canvas altogether, and had moved them about half an inch; but there they remained, and, the bottle was empty. | ‘ If there were no atmosphere surrounding the earth, only that part of the sky would appear light m which the sun was placed; and if a person should tarn his back to the sun, he would directly perceive it dark as night; for in that case there would be no substance to reflect the bright rays of the sun to his eyes. Itis owing to refraction that the sun enlightens the earth some time before it rises, and some time after it sets. See Parkes. * There are indeed, many other intermediate fluids, some natural, others artificial, between water and air; such as blood, milk, oils, wines, spirits, &c.; but water is a principal consti- tuent part of them all: some of them will be noticed in another part of this Essay. An examination of their properties would lead too far into chemical analysis, to be found generally in~ teresting.

But seventy-five parts of oxygen, with twenty-five of nitrogen, form nitric acid, or aqua- fortis, one of the most corrosive and destructive of all substances. None but a Being of infinite intelli- - gence could have had a conception how such different substances could be produced from the same prin- ciples.™ If the atmosphere contained one of them only— oxygen gas, or vital air, for instance, though every thing for one moment would wear a most flourishing aspect, yet the next moment, all animals and vege- tables would be in a state of putrefaction. If it were formed of the other only, (nitrogen and carbonic ' These three gases are nitrogen, oxygen, and carbonic acid gas, in the following proportions :---Suppose a portion of atmo- spheric air divided into a hundred parts ;_ seventy-eight of those parts would be nitrogen or azotic gas; twenty-one would be oxygen gas, or vital air, and one would be carbonic acid gas.

Plunged into such an atmosphere, animals would instantly expire; the vegetable creation would sicken and die. Ona proper mixture of these different airs, depends, ina great measure, the healthfulness of our atmosphere. Were any one of these component parts to prevail beyond the proportion in which it is generally found, in that exact proportion would the atmosphere be injured. What goodness is seen in this constitution of things! What wisdom appears in the nice adjustment of their proportions, and the combination of the whole! The oxygen gas, which is secreted by vegetables, is detained in the lower regions of the air, that it may combine with the nitrogen gas produced by animal respiration, to preserve the purity of the atmosphere. The carbonic acid gas, which is still heavier, and which is formed also by animal respiration and com- bustion, is confined within the reach of vegetables, which absorb it with avidity, and separate it into its original elements. * The quantity of carbonic acid gas which is formed by the respiration of animals and combustion, and the hydrogen and carbonated hydrogen gases which arise from marshes and stagnant pools, are so preju- dicial to the animal creation, that if some means were ee ee ee ® Parkes.

This evil is prevented by the structure of vegetables which feed principally on these gases, and whose organs seize upon them while they emit oxygen gas to renovate the atmosphere by its union with nitrogen, which is rejected by animal respiration. The wisdom, the simplicity, and the beneficence of this arrangement, are so striking, and address us with so much effect, that the mind of the Reader may be left to its own reflections on the goodness of God.° | The usefulness of this arrangement will be further apparent, when the known fact is considered, that the carbonic acid gas has the property of combining with putrid exhalations, and rendering them: in- noxious. It is therefore probable that a portion of this gas is diffused through the atmosphere for the purpose of uniting with malignant vapours as soon as they-are formed by putrefaction, and of pre- venting their dangerous effects. How great would be our exposure to perpetual infection, and constant diseases, without this benevolent contrivance ! The uses to which atmospheric air is destined, are most important.

Animals that live in water, require atmospheric air as well as others. Excluded from it, fishes soon die. Insects called hydrocanthari, have a curious apparatus for obtaining it. This is in their tails, which they raise above the water, and take ina small portion of air which they carry with them to the bottom, and keep it till it has lost its power of supporting life, when it is discharged, and the animal ascends for more. Sy being inhaled into the lungs of animals, the oxygen, or vital air, is immediately separated, and imparted to the circulating fluids, and is essential to animal life. With the food which they take into their stomachs, they receive a portion of air which aids the decomposition or the separation of its parts, and assists digestion. Air is also essential to the progress of vegetation; for when vegetables are excluded from air, they die. It enters their pores, and flows along with their juices through all their mysterious labyrinths. Rarefied by the external heat, it enlarges their vessels; again, condensed by cold, it occupies a smaller space: thus a sort of palpitation is produced by the alternate expansion and con- traction of their organs, which may aid the progress of vegetation. It is by means of air that the im- portant process of evaporation, and the consequent formation of clouds, is effected; for were air excluded, this process would not go on. The quantity of water evaporated from the surface of the sea and the land, by means of the atmosphere, INORGANIC MATTER. 25 WATER RAISED—CLOUDS FORMED. is vast beyond what most people suppose. Every ten square inches of surface of water, yields in vapour, every twenty-four hours, a cubic inch of water; and each square foot, half a wine pint; every space of four feet square, a gallon; a mile square, six thousand nine hundred and fourteen tuns; and a square degree of sixty-nine English miles will evaporate thirty-three millions of tuns a day; and the whole Mediterranean, computed to contain one hundred and sixty square degrees, at least five thousand two hundred and eighty millions of tuns each day.” Clouds are fortned probably of vast numbers of spherules, or small globes of water filled with air, which, being heated by the sun, become specifically lighter than the lower stratum of the atmosphere; and consequently, like so many balloons, ascend till they arrive atthe same temperature of air with their own in rarity. Being collected together, these spherules form clouds, which float along the denser stratum of air, till being pressed together, they form drops of water, which become again specifically heavier than the air which supports them, and consequently descend in gentle showers upon the earth. So that air contributes to the formation of clouds, the support and conveyance of them to different parts of the earth where the God of Providence sees them wanted, and forms a medium to prevent the water from * Philosophical Transactions. 26 INORGANIC MATTER.

Besides these, air is subservient to various other important purposes :—by refracting the rays of light, it diffuses them more widely over the earth; it sup- ports combustion; when agitated into winds, it aids the interests of commerce, and a variety of necessary arts of civilized society. Its separate properties act independently of the rest in various cases. Its pres- sure raises water in the pump. It is owing to this pressure, that water is retained in its liquid and use- ful state; not frozen; neither vapour :—were it not for this pressure, as soon as ice has imbibed heat enough to melt it, evaporation would immediately raise it into the atmosphere, where it would be re- tained, and dissipated in the higher regions.—Were it not for this pressure of the atmosphere constringing the vessels in animals and vegetables, the elastic fluids contained in the finer vessels would inevitably burst them, and life would become extinct.‘ By being rarefied in the lungs of animals, and expelled unfit for respiration, air ascends through the denser medium of the wholesome atmosphere, and.no longer annoys the animal. Were it not possessed of this property, it would form itself about their mouths 4 It has been calculated that the weight of air, which presses upon the whole surface of the earth, is equal to that of a globe ‘of lead sixty miles in diameter. ; INORGANIC MATTER.

Licur and Hear are those important fluids employed by the God of Nature to aid in car- rying on the curious operations ‘of vegetable and animal life. On the real nature and causes of these fluids, it becomes me to be silent, since the greatest philosophers that ever existed have differed very widely in opinion, and remain ‘yet at variance: how- ever, all agree that they are matter in a fluid state, and the most subtile of all those fluids with which we are acquainted.

If they be different modifications of the same body, they act separately under those different modi- fications ; for the one is often found carrying on its operations, where the other is not perceived’. Heat naturally tends to separate the particles of most sub- stances, and is, no doubt, one of the grand agents in promoting the digestion of food in the stomachs of animals. When it is withdrawn from fluids, in general they congeal. It is essential to vegetation ; for, without it, seeds will not germinate, plants cannot erow, neither can animals.

It is light which paints the lively green on the leaf; the red, the blue, the purple, and the unnumbered beau- ties on the flower. The velocity with which light passes from a lumi- nous body is almost inconceivable". It completes a distance of one hundred and sixty thousand miles in one second of time. The rays of light flowing from the sun, fall upon our atmosphere, (as before mentioned) when they are refracted and reflected in all directions, and cover at once one half of this globe ‘with their splendour, diffusing wherever they come, life and gladness. The air does not appear to be heated by the rays of the sun passing through it; but when they meet with an opaque body like the earth, heat is produced, and diffused through the surrounding atmosphere. This accounts for the fact, that the further we are eta et hl a al « Dr. Herschel imagines that the sun is an opaque body, probably an habitable world; and that the light and heat, which we receive from it, are owing to an atmosphere which it has of elastic fluids, of a phosphorescent nature, by the decomposition of which light and heat are evolved. He also thinks that light and heat are distinct fluids. g; 30 INORGANIC MATTER. HOW ATMOSPHERIC HEAT IS PRODUCED. removed from the surface of the earth, the colder we find it. This fact seems to countenance a recent and ingenious conjecture, that caloric, or the matter of heat, is not transmitted from the sun; but that it is a subtile fluid originally belonging to our earth. The author of this hypothesis supposes that the sun is the great agent in the production of heat, without imagining it a vast globe of fire. He represents the sun as a great store-house of light,—a power indeed the most active in nature, but no ways destructive. He thinks that light produces heat merely by ex- citing an insensible action between caloric and the particles of matter contained in bodies; and this system is more analagous to the general principles on which our globe is constructed, than that which is generally embraced, and enables us to solve the ereat difficulty concerning the distribution of heat among the different planetary bodies; for, according to this view, those nearest the sun may have no more than those at the most remote distance. We have only to suppose, says he, the quantity of caloric to be proportioned to the distance; and if a smadl quan- tity exists in the planet Mercury, no more heat may be excited than is done by a darger quantity in Saturn.” To intimate the glory of his own infinite essence, Jehovah represents himself to us under the metaphor ’ Physical and Metaphysical Inquiries. et et i - INORGANIC MATTER. bl —$—$—$—$—$——— SSS NATURE OF THE ELECTRIC FLUID. of Light. ‘God is light, and in him is no darkness at all.” The adorable Redeemer speaks of himself as being “the light of the world:” and affirms, that “those who follow him shall not walk in darkness, but shall have the light of life.” By the glory of his person, the brightness of his example, and the divinity of his instructions, he diffuses moral and_ spiritual light over a dark world. He is that to his church, which the sun is to our system—the source of all spi- ritual light, joy, and prosperity. He is a “light to lighten the Gentiles, and the glory of his people Israel.” There is another fluid in combination with this atmosphere, which we must not forget to mention It is Ex.ectriciry. Indeed, whether this be another fluid, essentially distinct from that of solar light and fire, is not yet determined. In many particulars _ they agree, and in some they differ*. Whether it be the same fluid or not, this is certain, that it is every where diffused through our atmosphere, and is em- ployed by the Hand of infinite power and intelligence, to effect many of the wonders of nature. It is a most powerful stimulant, and acts as such on both animal and vegetable organization.

As by it a con- siderable number of diseases are cured, so it is by no means unphilosophical to infer, that by it many diseases are prevented. It is found to be particularly serviceable in promoting the growth of plants: for plants which are placed adjacent to an electrical apparatus which is often used, grow much more rapidly than they do otherwise. And perhaps rain proves more fertilizing than other water, because, descending through the atmosphere, which is always possessed of a considerable portion of this fluid, it may be electrified, and every drop carry some of it to the earth. In the common operations of nature, the equi- librium is preserved, and the presence of the electrical fluid is not perceived; but when by any cause that equilibrium is destroyed, its awful powers appear in vivid lightnings, the roar of thunder, the rending of trees, the destruction of houses and their astonished inhabitants. ‘The Aurora Borealis, as well as thunder and lightning, and various other meteorological phx- nomena, show the presence and importance of this fluid in some of the grandest operations of nature, which may be explained by a knowledge of its INORGANIC MATTER. 33 Slee principles.

By Orcanizatton, is meant such an arrange- ment of the particles of matter as discovers design, where the constituent parts of a whole are so disposed as to be subservient to each other: and I apply the term to all those objects in creation, whether vegetable or animal, which are possessed of vessels for the cir- culation of fluids, and parts arranged with order and obvious intention. The objects of our globe, to which this definition is applicable, are exceedingly nume- rous. ‘To dwell on the peculiarities of each, would ‘be a task for the completion of which the longest ‘life would be totally insufficient. General remarks on organized bodies are, therefore, all that is in- tended, and all that can be expected in a work like the present. At what specific point this class of objects com- mences, is, perhaps, difficult to determine. The link which connects together the different orders of 38 ORGANIZED NATURE. SHELLS CONNECT ORGANIC AND INORGANIC BEINGS. x created beings, is frequently far beyond the reach of human observation; yet, from a knowledge of some cases, we have reason to suppose that such a link exists in all. The point at which inorganic matter stops, and from which organized nature commences, is, it may be, the shells of snails and other animals, which increase with the living creatures that inhabit them: for these shells seem to partake of the nature of both organic and inorganic matter. They are of a remarkably firm texture; and some of them are exceedingly strong and impenetrable. They form a sort of coat of mail to the animals which wear them, admirably adapted to resist the dangers to which they are commonly exposed. Though it is difficult to determine to which class of objects shells belong, yet the investigation of the most patient and skilful naturalists has determined them to belong to the class of organized bodies. M. Herissant, in the Memoirs of the Academy of Sciences for 1766, has discovered the. structure of shells to be organical. In the numerous experiments that he made on an immense number, and a very great variety of animal shells, he constantly found that they were composed of two distinct substances ; one of which is a cretaceous or earthy matter; and the other appeared, from many experiments made upon it by burning, distillation, and otherwise, to be evidently of an animal or membraneous nature, which (after he had separated the earthy matter from it) ORGANIZED NATURE. 39 = STRUCTURE OF SHELLS—THEIR COLOURS. exhibited satisfactory proofs of a vascular and or- ganical structure. He shows that this membraneous substance is an appendage to the body of the animal, or a continuation of the tendinous fibres that com- pose the ligaments by which it is fixed to its shell; and that this last owes its hardness to the earthy particles conveyed through the vessels of the animal, which fix themselves into, and incrust, as it were, the meshes formed by the reticular or net-like fila- ments of which this membraneous substance is com- posed.—On the occasion of the colours of different shells he remarks, that Nature, always magnificent in her designs, but singularly frugal in the execution of them, produces these brilliant decorations at a very small expense. The membraneous substance above-mentioned is plaited and rumpled in such a manner, that its exterior lamine, incrusted with their earthy and semi-transparent matter, form an infinite number of little prisms, placed in all directions, which refract the rays of light, and pro- duce all the changes of colour obseryable in shells." These, I conceive, constitute the lowest order of organized bodies, and the first above mere rude matter. * See Encyclop. Brit.—the word SHELL. 4i) ORGANIZED NATURE. STRUCTURE OF VEGETABLES. THE STRUCTURE OF VEGETABLES. —i—— - VEGETABLE substances, in which organization appears more evident and perfect, are the next I shall mention. Here organization is unquestionable, and bears a sort of analogy to that of animals. It is not, however, my intention to describe the nature and construction of different plants and vegetable pro- ductions at large—this is the province of the Bo- tanist; but those functions only which are common to all, or néarly all, and which appear essential to vegetation. ‘To excite an interest in the mind on this subject, let-it be recollected, that this order of productions is of the greatest moment to ANIMALS of all descriptions, rational as well as irrational; as it constitutes either their immediate food in its vegetable form, or indirectly, by affording food to the animals on which they feed. Were, therefore, the vegetable creation to be annihilated, or, which would amount to the same thing, were the organization. of vegetables to be destroyed, their species would cease to be pro- pagated, and the whole animal creation must ulti- mately perish. In order to unfold the wisdom of God in this part of creation, we must consider— ORGANIZED NATURE. 41 CONSTITUTION OF VEGETABLES.

As they are principally designed for the food and support of animals, it is rational to expect that, being formed under the immediate eye of infinite Intelligence, they will be found, on inves- tigation, to contain those essential ingredients which are adapted to these purposes. For though it be the design of the beneficent Creator to adorn the surface of the earth, and afford a pleasing gratification to the senses of man, yet these objects are manifestly subservient to, immediate utility: and a close atten- tion to a chemical analysis of vegetable substances shows that they are perfectly adapted to their design, and that they contain whatever is necessary to the support of animal life. The substances at present known to chemists, which they have not hitherto been able to decompose, amount to forty-eight: many of these exist in plants ; 42 ORGANIZED NATURE. CONSTITUTION OF VEGETABLES. the rest belong, exclusively, to the mineral kingdom ; for it is a fact, that no substance (we mean simple substance) has been yet found in the animal kingdom which does not exist also in vegetables.” Sir Humphry Davy enumerates the following compound substances found in vegetables :—gum, or mucilage, and its different modifications; starch, sugar, albumen, gluten, gum elastic, extract, tannin, indigo, narcotic principle, bitter principle, wax, rosins, camphor, fixed oils, volatile oils, woody fibre, acids, alkalies, earths, mefallic oxides, and saline compounds. By analyzing each of these products, we come at last to those bodies which we are at present obliged to consider as simple, because they have not yet been decomposed, and of which, accordingly, we must suppose that vegetables are really formed. Nearly the whole of vegetable substances are composed of four ingredients; namely, carbon, hydro- gen, oxygen, and azot. Of these, azot forms but a small proportion even of those vegetable substances of which it is a constituent part, while into many it does not enter at all: so that, upon the whole, by far the greater part of vegetable substances is composed of carbon, hydrogen, and oxygen. We do not men- tion caloric and light, concerning the nature of which > See Encyclop. Brit. Suppl. —_————— ORGANIZED NATURE, 43 ANIMAL PROPERTIES DERIVED FROM VEGETABLES. too little is known to enable us to determine with certainty into what substances they enter.° We are not to suppose that all these substances are to be found in the same plant: they have been discovered in those vegetables which haye been analyzed by chemists, and in various proportions in different plants.—How little do we think, when we are eating what, without a chemical knowledge of its component parts, we may suppose to be a simple uncompounded substance, that it contains properties which, when digested. in the stomach, contribute to form our blood, and the vessels in which it circulates, our bones, our muscles and tendons, our skin, nails, and hair. And how great must that wisdom be which directs the un-numbered particles of these substances to their proper situations, and so connects them with each other as to produce with certainty the intended result! The number of vegetables already known amounts to forty-four thousand : and new discoveries are con- stantly making. How astonishing, that so great. a variety, all differing essentially from each other, and all flourishing under the rays of the same sun, and growing in the same atmosphere, should be produced from a few simple substances ! | The essential principles of vegetables bear an evident relation to the structure and necessities of © Encyclop. Brit, Suppl. 44 ORGANIZED NATURE. ANIMALS ABLE TO MAKE A PROPER CHOICE. OF FOOD. animals. And God has wisely communicated to the vegetable economy whatever is necessary for the animal. In their most perfect state, indeed, vege- table substances, such as fruits, seeds, leaves, and whatever is fit for food, can contribute nothing to the support of animal life, until they undergo an entire decomposition, and a complete destruction of their organization in the stomach of the animal. But when that mysterious process has taken place, vegetables afford all the essential properties necessary for the support of animals. So that this relation between the animal and vegetable kingdom is such, that an essential alteration in the one would render - an equal change in the other indispensably necessary. What goodness, what intelligence, what wisdom does this discover in the Creator! He foresaw all the necessities of the animal system in its different stages of youth and maturity, and made suitable provision for every exigency. Some vegetables are suited to one class of animals, and others to another class; but they are all endowed with properties of appear- ance, or smell, or taste, whereby the animal, fur- nished also with organs adapted to these purposes, makes an infallible choice of that which‘is destined for its use by the Creator, and carefully rejects what is unsuitable, and would prove destructive. The most superficial observer of nature must be struck with the design which is every where obvious. We must stop, however, till we arrive at a superior state ORGANIZED NATURE. 45 THE WORKS OF GOD INCOMPREHENSIBLE. of existence before we can understand the whole scope of divine wisdom in this lower creation. Nay, it is questionable whether any created mind, at any period of its being, even the most remote, will be able to comprehend, perfectly, the minutest of the works of God. Probably no intelligence but that which is infinite can fully grasp the whole extent of wisdom as displayed in any one part of this mys- terious creation. | I might have considered here the nature of the ligneous part of vegetables, their bark, and their sap ; but their essential properties, when analyzed, are reducible to the substances which I have before men- tioned, and therefore it would be superfluous to treat of them distinctly. We find in them a singular combination of many of the known elements, blended in various proportions, in inumerable modifications, and under the influence of different circumstances, producing a variety of shapes, qualities, and colours, which must excite wonder and delight in the mind of every attentive observer. Having noticed the constituent principles of Vege- tables, I shall now consider— THE 46 ORGANIZED NATURE. THE ROOTS OF VEGETABLES. THE GENERAL STRUCTURE OF PLANTS, AND ITS SUIT- ABLENESS TO THE PROCESS OF VEGETATION. In this part of our subject, we shall be led to contemplate the innumerable particles of the sub- stances already mentioned, so arranged and disposed as to constitute organs and systems of the most. curious nature, and which afford an astonishing display of divine wisdom.—I begin with the S¢ruc- ture of Vegetables. All plants have Roos, which penetrate the soil in. which they grow, and reach to a considerable extent. These roots appear to subserve two im- portant purposes; the one is, to give a firmness and stability to that part which appears above the ground, to which they are well suited, extending in all directions horizontally in the earth to which they adhere ; so that if the plant is in danger of falling in one direction, they support it, not only as- props on that side, but also by holding it fast on the opposite:—the other purpose is, to supply the plant with its necessary nutriment, which it derives prin- cipally from the vegetable stratum in which it grows ; they are also well adapted to this purpose, for they are supplied with an inconceivable number of pores, which are so very small, that no gross and improper matter can enter; these pores are as so many mouths to the plant. They are connected with those small | : | ORGANIZED NATURE. 47 nn THE ROOTS OF VEGETABLES. —$—$—$<— vessels, which, like arteries and veins in the human body, extend through the whole vegetable system, passing through the wood, bark, and leaves; and becoming increasingly delicate the nearer they ap- proach to the extremities, which they are destined to enlarge, by conveying to them the fluids tended for that purpose. : The sap, in passing upwards, becomes denser, and more fitted to deposit solid matter: it is modified by exposure to heat, light, and air, in the leaves ; descends through the bark; in‘ its progress produces new organized matter; and is thus, in its vernal and autumnal flow, the cause of the formation of new parts, and of the more perfect evolution of parts already formed. At the above-named seasons of the year the sap rises most vigorously, at the time the temperature is variable; and if it be supposed, that in expanding and contracting, the elastic fibres of the silver grain exercise a pressure upon the cells and tubes containing the fluid absorbed by the capillary attraction of the roots, this fluid must constantly move upwards towards the points where a supply is needed.* From the root springs the Sram, which rises per- pendicularly out of the ground, and divides. itself into branches which gradually decrease in proportion eee ene etree testosterone anrunagulosepneasbsoverscseonirqresnscsavsins asp moceaigeremeagouosipi oesrendied Asermmntedechy Poasne maeerlescsmiiminnae®s " See Davy’s Agricultural Chemistry. 48, ORGANIZED NATURE.

Itis composed of small fibres which run parallel to each other in the perpendicular direction, and adhere so firmly as not to be easily separated. In the eentre of the stem is the pith, which is soft and very porous. It is inclosed in a fine thin membrane, and is generally supposed to give birth to an essential organ of fructification, which will afterwards: be mentioned. The whole stem is covered with a curious bark, which is com- posed of three layers, one over another. The outermost serves for protection; the other two in- crease. the diameter of the Stem. The Leaves are attached to the branches of plants: by means of foot-stalks, which grow off in different directions, forming two layers of a curious net-work, besides a covering over a sort of skeleton of fibres, of a firmer texture, to which these two layers are attached, the one above, and the other beneath. Through the slender foot-stalk, nu- merous fine vessels run from the branches, and are extended in all directions over the leaf. It appears, that the beautiful green foliage formed by the leaves; is not for mere ornament, but for use; for if a tree be stripped of its leaves in the spring, it soon dies.

If this be true, as many eminent physiologists suppose, then the leaves of plants compose an important chemical laboratory, for preparing their juices for future use, as necessary to the plant as the stomach is to the animal. | Of all the parts of plants, (says Sir H. Davy) leaves are the most refined, the most. beautiful in their structure, and appear as. the master-work of nature in the vegetable kingdom. The elegance of their tints, the variety of their forms, the delicacy of their organization, and the adaptation of their parts, are all calculated to awaken our curiosity, and excite our admiration.° | All kinds of vegetables, when assisted by the rays of the sun, have the power of decomposing water; during which decomposition, the hydrogen is absorbed, and goes to the formation of oil and rosin in the vegetable; while the orygen combines with part of the caloric received from the sun, and Is given out in the form of oxygen gas ; so that this one operation of nature gives nourishment, and pro- vides materials of growth to the vegetable world, and, at the same time, renovates that vital principle in the atmosphere which is necessary for the ‘sup- oro le a ee * Agricultural Chemistry. 50 ORGANIZED NATURE.

Surely nothing short of consummate wisdom could have conceived any thing so beautiful in design, or so extensively and superlatively useful in effect. That man must be strangely blind who does not see, in this general structure of vegetables, a remarkable suitableness to the mysterious process of vegetation, which the infinitely wise Creator designed to be conducted by it. Here is a singular adaptation of means to an end, and the end is accomplished by these means. Here is nothing wanting, nothing superfluous. If any essential derangement of or- ganization take place, the plant dies, and the end is defeated. The process of vegetation carried on in this surprising economy, has hitherto baffled the most acute philosophers. But little is yet known concerning it. The multiplicity of operations continually going on in vegetables at the same time, and the variety of different, and even opposite, substances formed out of the same ingredients, and almost in the same place, astonish and confound us. The order, too, and the skill with which every thing is conducted, are no less astonishing. No two operations clash; there is no discord, no irregularity, no disturbance 5 every object is gained, and every thing is ready for its intended purpose. This is too wonderful to * ‘Parkes.

No person has been able to detect the Acunt, always so busy, and performing such wonders, or to discover him at his work; nor have philosophers been much more for- tunate in their attempts to ascertain the instruments which he employs in his operations.* This agent has been called the vegetative prin- ciple. The nature of the vegetative principle can only be deduced from the phenomena of vegetation. It evidently follows a fixed plan, and its actions are directed to promote the good of the plant. It has a power over matter, and is capable of directing its attractions and repulsions, in such a manner as to render them the instruments of the formation, im- provement, and preservation of the plant. It is capable also of generating substances endowed with ‘powers similar to itself. The plan, according to which it acts, displays the most consummate wisdom and foresight, and a knowledge of the properties of matter infinitely beyond what man can boast." Though the vegetable system is constantly under the observant eye of the philosopher, and subject to his experiments and analysis, yet he has not been able to ascertain how a blade of grass grows. He can discover its general structure; he finds it a vascular, organized body; he will tell us that the * Encyclop. Brit. ” Thid. E 52 ORGANIZED NATURE.

But: does he therefore deny that there 1s such a process as vegetation? By no means. He fully believes it. But if, perhaps, we converse with this same philosopher on the mysteries of a divine revelation, he will tell us: that he utterly rejects them. If we inquire into the reason of this daring impiety, he will. reply, that he will believe nothing but what he can comprehend. But where is the consistency of this pretended philosopher? ‘here are two objects which claim a divine origin: there is nothing either in the one or in the other incon- sistent with the character of God. Like all other divine operations, they both contain unfathomable mystery: and yet, notwithstanding his avowed prin- ciple, the one he firmly believes, though he con- fesses it to be a mystery; and the other he rejects because it is a mystery! The Christian maintains that consistency of character to which the Infidel is a stranger.. Confessing his utter incapacity to com- prehend the modus of the divine existence, and that it must necessarily be mysterious to. finite minds, he justly expects to find in all the works of God something which he cannot comprehend. And so far from rejecting the doctrines of the Sacred Scriptures, on the ground of their being mysterious, ORGANIZED NATURE, 53 a VEGETABLES PROPAGATE THEIR KIND. a it is one reason why he embraces them. For if they did not possess this characteristic, they would be different from all the known works of God, and might. be rejected as the work of man, and a cun- ningly devised fable, | THE ORGANS WITH WHICH VEGETABLES ARE ENDOWED FOR THE PROPAGATION OF THEIR SPECIES, Secondly. That vegetables ought to possess organs for the continuance of their kind, is obvious; for those vegetables which continue the longest, are comparatively but short-lived. Therefore, whatever wisdom might appear in their first formation, there would be a manifest defect, seeing that their organs can act but a little time, and their species must fail, if they did not possess the means of perpetuating their kind ; unless, indeed, the Creator had resolved to continue them by successive new creations as soon as they perished. By their original formation, all the different orders of organized bodies were endowed with laws and powers for raising up a new ‘succession when the parent stock returned to dust. Now, though the vegetable creation subseryes a great number of useful purposes in its unripe condition, if uninter- rupted, it goes on toa perfect state, when it makes uniform provision for continuing its own kind, which 54 ORGANIZED NATURE.

Different orders of the vegetable kingdom pro- pagate their species in different methods; some by ~ shoots, others by bulb-roots, others by seeds : yet they all possess the functions necessary to this end. As supreme intelligence is the most evident in those which perpetuate their species by seeds, I shall con- fine my attention to them, and to those organs in them which are destined to the perfection of fruc- tification. Here I shall consider the apparatus which is necessary for forming and maturing the seed, and the suitable structure of the seed for raising up a new race of its own species. In both we shall be led to contemplate the surprising wisdom of God, in adapting the means to the object in view, and in securing the end by the appointed means. ‘The apparatus which is constructed for forming and maturing the seed, is the Frower of plants, which is a most astonishing contrivance. I shall here mention its various parts, with a short descrip- tion of each, and its uses in promoting the grand design. This description, indeed, does not abso- lutely apply to all flowers, ‘but to flowers in general. The outer bark of the slender foot-stalk, which is intended to support the flower, diverges from the centre all round, either with its fibres connected, or separated into green or other coloured leaves. This ORGANIZED NATURE. 55 ———— THE STRUCTURE OF FLOWERS. (CALIX) cup is appointed to inclose, support, and protect, the (coroiLa) beautiful flower within. The flower is formed by the unfolding of the inner bark of the plant, which is either connected all round, as in the fox-glove, or divided into (PETALS) leaves, as in the pink. ‘This delicate part, being exposed to the action of the light and heat of the atmosphere, is frequently adorned with the most brilliant colours. It is also intended to defend the interior parts, especially the (sramina) threads, or chives, which proceed from the wood of the plant, and appear mostly in a perpendicular position, in some instances pendulous. Each stamen is divided into two parts ; the (FILAMENT) thread-shaped part of the stamen which serves as a foot-stalk to support the (ANTHERA) part which is properly called the flower, from. its great utility in fructification ; it is the summit of the filament, and produces the POLLEN, or FARINA, which appears like small dust or meal lying on the top. The farina is the fructifying principle of the plant; and no seed can be produced without it. At the centre of this surprising economy appears the (PisTrLLUM) pistil, which proceeds from the pith of the plant. This is generally found erect in the centre of the flower, in’ the midst of the stamens. Its base is the (GERMEN) bud, which is intended to contain the seed. From this foundation rises a small pillar (sryLus), which supports the (str¢m) mark, or head; in some flowers it is a single knob, Fd 56 ORGANIZED NATURE. SCENTS OF FLOWERS—PROCESS OF FRUCTIFICATION. in others there are more than one, but in all it is moist. | Almost all flowers emit a peculiar fragrance, which depends upon the volatile oils they contain; and these oils, by their constant evaporation, surround the flower. with a kind of odorous atmosphere ; ° which, at the same time that it entices larger insects, may probably preserve the parts of fructification from the ravages of smaller ones. Volatile oils, or odorous substances, seem particularly destructive to these minute insects and animalcules, which feed on the substance of vegetables; thousands of aphides may be usually seen on the stalks and leaves of the rose; but not one of them is ever observed on the flower.’ ? | According to Linnus, the following is the pro- cess of fructification carried on by this curious mechanism. He affirms, that “the farina is con- veyed by means of the wind, or insects; to the moist stigma, where it remains until it discharges a sub- tile fluid, which, being absorbed by the vessels of the stigma, 1s carried to the seeds, or ova, and im- pregnates them.” He proves this by shewing that if either the pistil.or stamina be destroyed as soon as the flower blows, either no seed will be produced, or, if there be any, it is barren. He observes fur- ther: ‘‘ When the flowers are in full blow, and the ‘ See Davy’s Agricultural Chemistry. _wwo a — eS Uhh | | ORGANIZED NATURE, | 57 INFLUENCE OF THE FARINA ON THE SEED. pollen flying about, every one may then see the pollen adhering to the stigma. The stamina and pistilla, in most plants, are of equal heights ;. that the pollen, by the intervention of the wind, may, with the greater facility, fall.upon the stigma. The stamina of most plants surround the pistillum, to give the pollen an opportunity of falling upon. the stigma at every breeze of wind. The flowers. of many plants expand by the heat of the sun, and shut themselves up in the evening, or in rainy weather, The final cause of this must be to keep the moisture from the pollen, lest it should be thereby coagulated, and of course prevented from being blown upon the stigma. As the pollen is specifically heavier than air, such flowers as have their pistillum longer than the stamina, hang down, or incline to one side. An easy admission of the pollen to the stigma is the final cause of this appearance.” The vegetable creation affords us many instances of the most curious mechanism, illustrative of these statements, to shew the necessary influence of the farina on the formation of the seed. There is a remarkable fact observable in the Coxttinsonra. The two stamens stand wide by diverging from each other, and the pistil bends itself into contact first with one of them, and after some time, leaves this, and applies itself to the. other. The reason may be that one of the anthers may ripen before the other ; but the fact is curious. 58 ORGANIZED NATURE. SINGULAR INSTANCES OF FECUNDATION,. In the Sparrium Scoparivm, or common broom, the stamens are in two sets, one rising a quar- ter of an inch above the other; the upper set does not arrive at its maturity so soon as the lower, and the stigma is produced amongst the upper, or immature set; but as soon as the pistil grows tall enough to burst open the keel-leaf, or hood of the flower, it bends itself round in an instant, like a French-horn, and inserts its head, or stigma, amongst the lower or mature set of anthers. The pistil continues to grow in length; and, in a few days, the stigma arrives again among the upper set by the time they become mature. This wonderful contrivance is readily seen by opening the keel-leaf of the flowers of the broom before they burst spontaneously. A similar contrivance appears in the Boxtora. The two lower stamens become mature before the two higher. After they have shed their dust, they turn themselves away outwards, and the pistil, con- tinuing to grow a little taller, is applied to the upper stamens. | | I mention again, the DoprcarHreon, or Ame- rican cowslip. ‘The pistil is much longer than the stamens; hence the flower-stalks have an elegant bend, that the stigma may hang downwards to receive the fecundating dust of the anthers, And the petals are beautifully turned back to prevent the rain, or dew-drops, from sliding down and wash- ing off this dust prematurely; at the same time ee ee ee eee Se, ORGANIZED NATURE. 59 ‘ a , . SINGULAR INSTANCES OF FECUNDATION, exposing it to the light and air. As soon as the seeds are formed, it erects all the flower-stalks, to prevent them from falling out. | The petals of the beautiful flower called Gro- RIOSA,: with three of the stamens which are first mature, stand up in apparent disorder, and the pistil bends at nearly a right angle to insert its stigma among them. In a few days, as these decline, the other three stamens bend over and approach the pistil. In the Frirrnyarta Persica, the-six stamens are of equal length, and the anthers lie at a distance from the pistil; three alternate ones approach first, and when these decline, the other three approach. In the Lirurum Srricarra, which has twelve stamens and one pistil, a beautiful red flower grow- ing on the banks of rivers, six of the stamens arrive at maturity and surround the pistil some time before the other six; when these decline, the other six rise up and supply their places. — In the Katuria, the ten stamens lie round the pistil like the radii of a wheel; and each anther is concealed in a niche of the corolla to protect it from cold and moisture: these anthers rise separately from their niches, and approach the pistil for a time, and then recede to their former stations. * It deserves also to be remarked, that saccharine matter is found in the nectarium of flowers, or the * See Darwin's Works. 60 ORGANIZED NATURE. HOW SEEDS ARE PROTECTED. receptacles within the corolla; and by tempting the larger insects into the flowers, it renders the work of impregnation more secure; for the pollen by their means is applied to the stigma: and this is particu- larly the case when the stamens and pistils are in different flowers, or different plants.’ : Not only are means appointed for the production of the seed, but also for its preservation. The bud being matured, it becomes a seed vessel (PERICAR- PIuM,) surrounding the enclosed fruit to defend it from danger; such as pods, nut-shells, and the stones of wall fruits, which either burst to diffuse the seed around, or fall off from the parent plant to the ground, where it is still preserved till the season of germination returns. Besides these, seeds have a firm and suitable covering (aRtLLus) of their own, for the preservation of the essential parts of fructi- fication. | Having considered the curious provision which is made for forming, maturing, and preserving the seed, I shall notice the suitable. structure of THE SEED itself for raising’ up a new race of its own species. | We may form an idea of all other seeds by the structure of a pea, a bean, or the kernel of a melon: the formation is nearly the same in all.

ORGANIZED NATURE, | 61 STRUCTURE OF SEEDS, and we generally discover two pieces’ which are separated with ease; these are called the Loses of the seed: they are nothing else but the composition of a kind of meal for the nourishment of the young plant. At the top of the lobes is the bud, sunk in Jike a small stud. It is composed of a SrocxK and a Prpicie, which last will afterward be the roat. The stem or body of the minute plant is sunk a little into the inward substance of the seed; and the pedicle, or small root, is that point which first appears when the seed begins to germinate. The pedicle is connected with the lobes by two branching. tubes, whose ramifications are dispersed through the lobes, from which they derive the support necessary for the young plant. The stock or body of the plant is enclosed by two leaves, which are destined for its preservation till it appears above the ground. These two leaves are the first parts of the plant which disengage themselves from the seed, and are the har- bingers of the TrRunxK, the exceeding delicacy of whose texture they protect till more matured, and then fall off. After the tender root has been nourished for some time by the lobes, it shoots in various directions into the earth, and derives from it that support. which it ceases to collect from the lobes. All seeds, whether small or large, contain the above-mentioned parts, under some modification or other, wrapped up carefully in one or more coverings appointed for the protection of the whole enclosed 62 ORGANIZED NATURE. THE POWER OF GROWING VEGETABLES. curious apparatus. The seed being of the highest importance to the resources of nature, it is defended above all other parts of the plants; by soft pulpy substances, as in the esculent fruits; by thick mem- branes, as in the liguminous vegetables; and by hard shells, or a thick epidermis, as in the palms and grasses.” | Though the tender bad, which seems unable to overcome the least resistance, is enclosed in tough skins, and hard and strong shells and stones, which we can scarcely break, yet it makes its way through all these obstructions with the utmost certainty. When the proper season of germination arrives, the lobes swell, burst their various coverings, and afford an opportunity for the bud to escape. The PowER of growing vegetables overcomes great obstructions, The following fact is well authenticated :—In the town of Basingstoke, in Hampshire, one of the flag- stones of the foot-path was raised considerably above the rest. When the mason, who was employed to put it into its place again, took it up, a large mush- room, six or seven inches in diameter, was found | growing under it. However, it could not be con- ceived that the mushroom had raised the:stone. Soon after, the adjacent stone was also raised; on its being taken up, two mushrooms of smaller size were found growing under it. Several credible witnesses of the " Davy's Agricultural Chemistry. : : ! ORGANIZED NATURE. 63 - \ SEEDS RETAIN THEIR ORIGINAL FORMS. fact were fully convinced that the stones were raised by the growing of the mushrooms. The stones were twenty-four inches by twenty-one, and two inches thick, and weighed eighty-three pounds each.” In whatever position the seed falls into the ground, the sprout and the root take their proper directions with absolute infallibility ; the root never seeking its nourishment in the air, nor the sprout in the ground: each seeks its nourishment in its own element, and contributes what it collects to the general design. And it deserves to be noticed, that divine Providence has provided the elements of ger- mination on every part of the surface of the ground ; water and pure air and heat are universally active; and the means for the preservation and multiplication of life are at once simple and grand ! Were any of these parts wanting in the formation of a seed, the whole would be useless. But through all the generations of many thousand years, not one property has been lost, no new organ gained. Every _ seed has communicated its perfect conformation to the plant to which it gave birth; and that plant has produced another crop of seeds of the same shape, size, qualities, and organs, as that which gave it existence. Were there no other demonstration of a ‘supreme Being, and the infinite wisdom of that Being, than this order of organized matter affords, the man — * See Monthly Magazine for October, 1817. 64 ORGANIZED NATURE. ! ae —— who denied these important truths would give sad evidence either that he was destitute of reason, or that he knew not how to use it. Plants. not only possess a proper organization for the production: of seed, but also MEANS YOR ITS DISPERSION abroad, at a distance from the parent plant. This subject is worthy. of notice. Some seeds are provided with a small tuft of light soft down; (caronalia) as that of the thistle and many others, which, when blown by the wind, carries the seed to a considerable distance. One hundred and thirty-eight genera are found to have those wings, which have been known to carry their seeds fifty miles from the plant that gave them birth. There. are fifty genera whose seeds are enclosed in seed-vessels, which open with violence, and scatter them around. Linneeus mentions fifty genera more, whose seeds are provided. with hooks, which may adhere to the coats of animals, and by this means be dispersed. One hundred and_ ninety-three are mentioned, whose seeds are deposited in berries, which are eaten by birds and other animals, Those plants which we find growing on the tops of walls, houses, and rocks, have had their seeds brought to these places by this means. The seeds of some of the mosses are so minute, that they float in the air like atoms, and are every where dispersed. Many seeds are supplied with a kind of bristles, which, being expanded by moist, and contracted by dry ORGANIZED NATURE. | 65 SINGULAR MECHANISM IN PLANTS. weather, are found to creep along the ground a con- siderable way. Other seeds are dispersed by rivers and seas, many miles from their birth-place. Many of the seed-vessels, open only at. the apex, and standing upright on the summit of a strong stalk, considerably raised. from. the ground, the seeds which they contain can. only be shaken out by violent winds. _And now, I would ask, could infinite wisdom have devised methods better adapted than these to the distribution and dispersion of seeds? I. shall here mention an instance or two in which there is a remarkable mechanism in the structure of plants for the propagation of their species, and the security of the seed. When the seeds of the Cycramen are ripe, the stalk of the flower gradually twists. itself spirally downwards, till it touches the ground, and forcibly penetrating the earth, lodges its seeds, which, being found not to grow in any other situation, are thought to receive nourishment from the parent root. is The Trrrotium Susrerraneum, (subterrane- ous trefoil) is another plant which buries. its seeds, the globular head of the seed penetrating the earth. This, however, may be-only intended to conceal the seed of this plant from the ravages of birds; for there is another trefoil, the Trrrotium GLoposum, or globular woolly-headed trefoil, which has a curious manner of concealing its seeds; the lower F 66 ORGANIZED NATURE. VEGETABLES ANSWER VARIOUS ENDS. florets only have corols, and are fertile; the upper ones wither into a kind of wool, and forming a head, completely hide the fertile calyxes.° The more ends that are accomplished by the same apparatus, or system of organs, the more we admire the ingenuity which contrived it. Let us apply this observation to the constitution of vege- table organization, and we must be struck with the variety of purposes to which it is adapted. In the vegetable kingdom, animals find food for their sub- sistence ; and notwithstanding the great variety of their tastes and constitutions, here is as great a variety of provisions. Though no vegetable, per- haps, is exclusively designed for medicine, yet, what is the food of one class of animals, is medicine for another; and every animal finds a remedy for the maladies to which it is subject. Many of the seeds are lodged in beds of pulpy matter of various degrees of consistence, as those of apples, plums, and peaches, which is at once subservient to the maturing of the seed; and, when that end is accomplished, affording a delicious repast to man and the brute creation. While the various tribes of herbs produce fodder for cattle, trees answer a variety of purposes in civilized life. And when they decay, and become unfit for use in their organized state, they enrich the Le — ° Darwin.

In every condition, each object answers some valuable purpose which is indispensably necessary. ‘The roots, the stems, the leaves, the bark, the flowers, the seeds of plants, all contribute their respective aid to continue their species, and subserve purposes of utility. Could blind chance produce so much regularity of operation, so perfect an adaptation of means to ends? No: it were beyond the wisdom of any created intelligence. It is alone within the compass of the Infinite Mind. The same wisdom is apparent in THE PECU- LIAR STRUCTURE of some particular vegetables. A few remarks on these shall close this part of the subject. MARINE PLANTS, which grow upon the rocks washed by the sea, are in great danger of being torn to pieces by the constant motion of the waves. But the structure of many of them is truly admirable, to secure them from injury. They are sup- plied with natural buoys which keep the plant floating in the water, and preserve it from being destroyed by the sharp protuberances of the rock on which it grows. ‘These buoys are hollow vessels, filled with air, placed up the stem, and in the leaves of the plant, and render it specifically lighter than water. They are also supposed to contain F 2 ae ORGANIZED NATURE. UTILITY OF THE COCOA-NUT TREE. the organs necessary for the propagation of their species.? Plants which have holiow stalks, such as wheat and oats, and various grasses, have an epidermis which contains a considerable quantity of silecious, or flinty matter; this, at the same time, affords strength to these delicate stems, and protects them from the attacks of insects. It seems to perform a part in the economy of these feeble vegetable tribes, similar to that. performed in the animal king- dom by the shell of the crustaceous insects.’ The structure of the Cocoa-nuT tree is well deserving of our attention; it supplies the natives of those countries, where it grows, with almost every thing necessary for their use ;—bread, water, wine, vinegar, brandy, milk, oil, sugar, honey, needles, thread, linen, clothes, cups, spoons, ‘besoms, baskets, paper, masts for ships, sails, hammocks, cordage, nails, : coverings for their houses, fuel, mats, and sacks, The Maldive cocoa-nut is esteemed by the in- habitants of those islands, a powerful antidote against the bite of serpents, and other poisons.

Besides making excellent hedges for their fields, its trunk serves for beams in the roofs of their houses, and its leaves for tiles. From these leaves they obtain paper, thread, needles, clothing, shoes and stockings, and cordage; and from its copious juice, they make wine, honey, sugar, and vinegar. Of the trunk; and the thickest part of the leaves, when well baked, they make a tolerable dish of food. It is also a powerful medicine in several disorders. : The leaves of a certam plant, which grows in the island of Jamaica, called there the Wiip Pine, are so constructed with bags underneath them, as to receive the rain which falls on their upper surface ; and when these bags are full, the orifice closes, so as to prevent any evaporation of the water. In the mountainous and other parts, when there is a great scarcity of water, this reservoir is not only sufficient for the nourishment of the plant, but it often sup- plies men, birds and insects. The Drovprine- TREES, in the islands of Ferro, St. Thomas, and in Guinea, serve the inhabitants instead of rain and fresh springs. The Cinnamon-rree of Ceylon, is another instance of peculiar usefulness. From the root is extracted camphire and its oil; from the bark of the trunk is obtained the real oil of cinnamon; from the leaves, an oil like that of cloves; out of the fruit, a juniper oil, with a mixture of those of cinnamon 70 ORGANIZED NATURE, and cloves. By boiling the berries, a kind of wax is obtained with which are made candles, ointments, and _ plasters." I shall now mention an instance or two of plants which contain a singular mechanism in their struc- ture, remarkably adapted to the necessity of their circumstances, or peculiar purposes, The VALLISNERIA is of this description. It is found in the river Rhone. ‘These plants have their roots at the bottom of the river. The flowers of the female plant float on the surface of the water, and are furnished with an elastic spiral stalk, which extends as the water rises, or contracts as it falls; this rise or fall, from the torrents which flow into the river, often varying many feet in a few hours, The flowers of the male plant are produced under water; and, as soon as the fecundating farina is mature, they separate from the plant, rise to the surface, and are wafted by the air, or borne by the currents, to the female flower.* Our attention, says Dr. Pauey, in this narrative, will be directed to two particulars: first, to the mechanism, the elastic spiral stalk, which lengthens or contracts itself ac- cording as the water rises or falls; secondly, to the provision which is made for bringing the male flower, which is produced under water, to the fe- male flower which floats upon the surface. * See Ray, * Darwin’s Botanic Garden. ORGANIZED NATURE, _ 71 eae eee THB CUSCUTA EUROP4A—VENUS’S FLY-TRAP. I make the follawing quotation from the same elegant author, who relates the fact on the authority of Wirnerine. “ The Cuscura Europa is a parasitical plant. The seed opens, and puts forth a little spiral body, which does Not seek the earth, to take root, but climbs in a spiral direction, from right to left, up other plants, from which, by means of vessels, it draws its nourishment. The little spiral body, proceeding from the seed, is to be compared with the fibres which seeds send out in ordinary cases; and the comparison ought to regard both the form of the threads and the direction they take. They are straight ; this is spiral. ‘They shoot down- wards ; this points upwards. In the rule, and in the exception, we equally perceive design.” Sensitive plants possess a peculiar mechanism, and a degree of irritability, and power of motion, which bear a strong analogy to animal bodies. The Dionza Muscipcta, or Venus’s fly-trap, is a sin- gular instance. It grows in America. Its leaves are joined, and furnished with two rows of strong prickles ; their surfaces covered with a number of minute glands, which secrete a sweet liquor that allures the approach of flies. When these: parts are touched by the legs of flies, the two lobes of the leaf instantly spring up, the rows of prickles lock themselves fast together, and squeeze the unwary animal to death.t Nor do the lobes ever open again ‘ Smellie’s Philosophy of Nature. 472 ORGANIZED NATURE. See CURIOUS PLANTS. * , while the dead animal continues there; but if it can | be removed without straining the lobes, they expand | again. If, however, force be used to open them, . so strong has nature formed the string of their fibres, that one of the lobes will generally snap off rather than yield." | | Buds, flowers, and fruits, which are susceptible of injury from the cold and dampness of the night, are provided with means of protection. The leaves of the chick-weed, and various others, are disposed in opposite pairs. During the night they become erect, and are so closely united, that they conceal and protect the flower. The leaves of the tamarind- tree contract round the tender fruit, and protect it from the nocturnal cold. The leaves of the white LUPINE, during the night, hang down, and cover and protect the young bud. The inference, furnished by these striking facts, is too obvious to require that it should be specified. Final causes were in contemplation worthy of Deity. The intermediate arrangements in order to them, discover the most perfect foresight of all the inter- posing difficulties, and a wisdom im rendering them subservient to the ends proposed, which must strike every: mind, and fill us with equal wonder and delight.* | Pe 1 onaieens Dun gee) ax visemodt.. “ Encyclop.

She disdains, as Mr. Lightfoot has remarked, to be limited by the systematic rules of human invention. She never makes any sudden starts from one class or genus to another, but is regularly progressive in all her works, uniting the various links in the chain of beings by insensible connexions.” ¥ There are some bodies which appear partly vege- table and partly animal; which have a mouth for the reception of food, a stomach for the purpose of digesting it, and other indications of proper animal formation ; and yet, unlike animals in general, they have not the power of locomotion, being stationary, growing upon a rock: such is the oyster and some others, which are still more stationary, as the po- lypus. When we compare animals and vegetables together, each in their most perfect state, nothing can be easier than to distinguish them. ‘The plant is confined to a particular spot, and exhibits no marks of consciousness or intelligence; the animal, on the contrary, can remove at pleasure from one place to another; is possessed of consciousness and a high degree of intelligence.

These machines, by means of different organs, have the power of converting other animals and vegetables into their own substance. By this assimilation, all their dimensions are increased, and their various parts uniformly preserve the same pro- portions with regard to each other, and continue to perform their respective functions.* But while these things may be said of the vegetable and animal creation in common, we feel it difficult to draw the line where the one terminates and the other begins. It is not necessary to dwell longer on this sub- ject. My intention is to describe those bodies which are indisputably of the animal kingdom, in order to deyelop the wisdom of the adorable Creator in their formation, and in bestowing upon them an organization most wonderfully adapted to the pur- poses of such formation. This part of our subject I shall consider under a two-fold division. Jn the jirst, I shail describe the Organs of Animated Na- ture, so far as they are essential to the fulfilment of the ends of their creation :—and in the second, * See Smellie’s Philosophy of Natural History. 76 ORGANIZED NATURE.

GL PL IPOS LG THE ORGANS OF ANIMATED NATURE, SO FAR AS THEY ARE ESSENTIAL TO THE FULFILMENT OF THE PURPOSES OF THEIR CREATION. As different animals are frequently destined to exist in different elements, and sometimes in’ those which are of a nature very contrary to each other, it is obvious that no one description of organization would be suitable to them all. ‘That which is suitable for living in water, is unsuitable for an existence on land. Each situation demands a for- mation peculiar to itself; and infinite and unerring skill has bestowed a system of organs most exactly adapted to the station which the animal is to occupy. This is observable through the whole range of the known creation. SPOOL PPOL M WINGED ANIMALS. There are many animals which live principally in the air, or convey themselves through it from place to place in quest-of food, such as winged insects and birds. ORGANIZED NATURE. 77 STRUCTURE OF EGGS~—BIRDS. I shall first consider Birps, and then proceed to INseEcts. r All Birds are produced from Eaes, the structure of whose shells, and their use in the formation of the young bird, are not generally known, and cannot be sufficiently admired, Egeg-shells are composed prin- cipally of carbonate of lime (chalk) and phosphate of lime. The body of the egg contains neither of these substances ; but, as both are wanted, it was neces- sary that they should be provided in some other way; which we find in the structure of the shells: and, the fact is, that during the whole time of incubation, the shells become thinner and thinner, till the embryo animal has appropriated a sufficient quantity of lime for the formation of its bones, (for lime forms the basis of animal bones). A part of the albumen, or white of the egg, combines with the shell, and another portion forms feathers. If birds cannot obtain any calcareous earth, they lay their eggs without shells ; but such eggs are not prolific. The general structure of Brrps, is that of light- ness. ‘Their bodies are small in proportion to their wings. Their bones are slender, very porous, and light, and have received the best conceivable shape for strength in which they could be formed, consider- ing the quantity of matter they contain; and the most strength is given to those parts in which it is the most required. The muscles of their wings are remarkably strong, and especially in those birds 78 ORGANIZED NATURE. WINGS OF BIRDS—THEIR INTERNAL STRUCTURE. which continue long in the air; as, for instance, those which migrate, and such as collect their food in the air, as swallows. Their wings are the best formation for flying that is possible: they are long and light. ‘Towards the fore-part there is a strong bone, and a kind of cartilaginous substance into which the feathers are inserted. The feathers are the strongest at this part, and grow gradually weaker towards their extremities. It is by this means that the bird is enabled to make its progress through the air; for striking the air by the motion of its wings, and meeting with resistance from it, the weaker end of the feathers yields, and conse- quently gives the bird a sliding direction forward. But if the wings were as strong at the hinder extre- mity as they are at the front, the bird would not be able to proceed. Such is the formation of the wings of insects, as well as birds; though in them a thin membrane supplies the place of feathers. Birds have received a remarkable interior struc- ture to fit them for flying, and to render them buoyant in the atmosphere. Their lungs are large, and well adapted to the reception of the greatest quantity of air possible for their size. This is not all. There are various air-bags disposed in different parts of their bodies, connected with the lungs by tubes. Besides these, the bones themselves contain pores and tubes almost through the whole system, for the reception of air from the lungs. The air received into the lungs, ORGANIZED NATURE. | 79 STRUCTURE OF FEATHERS. the air-bags, and the pores and cavities of the bones, must be considerable. This being rarefied by the natural heat of the bedy, no doubt greatly assists them in ascending and flying in the atmosphere. The Coverine of birds is at once most perfectly adapted to the preservation of heat, and the exclusion of extreme cold and wet from the skin, while it adds the least possible incumbrance to the body. Professor Sir H. Davy observes, that animal and vegetable substances in general are very bad con- ductors of heat: thus the hair and wool of animals, and the feathers of birds, are admirably fitted to protect them from the cold, and they enclose and retain air, which, being a still worse conductor, en- hances the effect. | The formation of the Fraruers is singular. They afford an additional. argument in favour of the being and boundless intelligence of God, which must bear down the weak objections of sceptics and atheists. Let us consider their general structure. The Quit is composed of layers of fibres one over another. The fibres of the external covering run in a circular direction, and bind together, like so many hoops, the inner fibres, which run parallel to each other lengthways. Strength and lightness are remarkably apparent. ‘The pith, by which they are supported, is astonishingly light. The Vanz of ~~ * Chemical Philosophy. 80 ORGANIZED NATURE. THE VANES OF FEATHERS. the feather is composed of various thin flat filaments, placed on each side of the shaft with their longest basis at right angles to its length: this gives the vane the greatest strength of which it is capable for meet- ing the resistance of the air. These filaments are placed close together ; they are supplied with teeth or hooks, which grow on each side, and consequently connect themselves with each other, and afford mu- tual support and strength. No contrivance could be more mechanical, or better adapted to the end of its formation”; and yet it requires so small a quantity of matter, that a feather is but very little specifically heavier than the air through which it assists the bird in flying.— Who but an infinitely wise Being could collect materials so essentially different from all the other constituent principles of the fowl, so. different from its flesh and blood and bones, .and produce such an arrangement? ‘rifling as a feather is, it discovers more intelligence and foresight than all the most ingenious devices of mortals put together ! and what vast variety of colours; how splendid and beautiful! On the same bird—on the same. feather, we often contemplate an assemblage of colours infinitely beyond the production of human art:— “Solomon in all his glory was not arrayed like one of these !” eo pene, ’ Spec. de la Nat——Durham’s Physico. Theol. —Paley’s Nat. Theol. ORGANIZED NATURE. 81 EEE ££££-222,,,£:,-— eee BIRDS OIL THEIR FEATHERS. — The disposition of these curious productions over the body of the fowl, is deserving of notice. They lie in a direction contrary to that in which the bird flies, and are placed one over another, like tiles on the roof of a house; so that at every point we mect with a stratum several feathers deep. Suppose they were placed in a contrary direction, and it would be impossible for the bird to fly; for the resistance of the air would raise them into an erect position, and counteract the progress which the bird would otherwise make by the stroke of its wings. And even all the filaments, which form the vane of the feather, incline towards the tail. But the feathered tribe are perpetually exposed to wet and cold. And though the formation and disposition of their feathers are admirably adapted to resist them, yet in a dry state they cannot do this. Divine Wisdom has therefore made provision to meet their necessity, and bestowed upon this race of beings an instinct which directs to the use of it. On the posterior extremity of the body is placed a protuberance of oily matter, supplied with a sort of nipples, which, when pressed by the beak, yield their contents; with this the bird oils and dresses its feathers all over. And as birds are unable to reach the top of their heads, and the upper ex- tremities of their necks, when they have dressed _ the other parts of the body, they rub their heads upon them, and thus effect what could not otherwise be G $2 | ORGANIZED NATURE. a we THE USE OF THE TAILS OF BIRDS. accomplished. As water-fowls are more exposed to the wet than others, in them this provision is more. abundant, and their bills are generally wider, and better adapted to the use of it. How often do we see them standing on the brink of the water, per- forming this necessary operation, and then launching in as secure against the insinuating element, as if they were clothed with materials of the firmest texture. The wings of fowls serving them for oars to move them forward, their tails answer -the same purpose as a rudder does the ship. ‘The tails of those birds are the longest which fly with the greatest rapidity, in order that they may have the most ready command of themselves in turning to the right or left, mounting up or descending. ‘Though this re- mark does not apply in all cases, it generally holds good. When a bird flies in a straight line hort- zontally, its tail lies in the plane of its path; but when it wants to alter its course up or down, or obliquely, it points its tail the same way, which, meeting with resistance from the air, brings its head into the same direction. Can a more ingenious con- trivance be conceived? Human. sagacity has not been able to furnish a better; and therefore art has taken the intimation of nature, and applied the same expedient, under a different modification, to the government of the ship. | As I purpose offering a more minute description of the general structure of the eyes of animals in another ORGANIZED NATURE, THE EYES OF BIRDS. ee ROI MECN WET RETA place, my remarks here, on those of birds, will only extend to the particulars in which they differ from others. Some peculiarities of the Eyes or Fowrs are thus described:—‘ As most of these creatures are continually employed in hedges and thickets, there- fore, that their eyes might be secured from injury, as well as from too much light when flying in the rays of the sun, there is a very elegant mechanism in their eyes. A membrane rises from the internal canthus, which, at pleasure, like a curtain, can be made to cover the whole eye; and this by means of a proper muscle that rises from the sclerotic ‘coat, and, passing round the optic nerves, runs through the musculus oculi attollens (by which, however, the optic nerves are not compressed) and palpebra, to be inserted into the edge of this membrane. When- ever this muscle ceases to act, the membrane, ‘by its own elasticity, again discovers the eye. ‘This cover- ing is neither pellucid nor opaque, both which would have been equally inconvenient ; but being somewhat- transparent, allows as many rays to enter as to make any object just visible, and is sufficient to direct them in their progression. By means of this mem- brane it is that the eagle is said to look at the sun.”* “The eyes of animals,” says Dr. Paley, “ which follow their prey by night, as cats and owls, possess a faculty, not given to those of other species ; namely, yeh AS ese ah Ik * Encyclop. Brit. Comparat. Anat. G 2 84 ORGANIZED NATURE. a —— EYES OF BIRDS ADJUST THEMSELVES TO DIFFERENT DISTANCES. of closing the pupil entirely; the final cause of which seems to be this: It was necessary for such animals to descry objects with very small degrees of light. This capacity depends upon the superior sensibility of the retina; that is, upon its being affected by the most feeble impulses. But that ten- derness of structure which rendered the membrane thus exquisitely sensible, rendered it also liable to be offended by the access of strong degrees of light. The contractile range, therefore, of the pupil is increased in these animals, so as to enable them to close the aperture entirely, which includes the power of diminishing it in every degree; whereby, at all times, such portions, and only such portions of light are admitted, as may be received without injury to the sense.”4 | As the beaks of birds are short, it is necessary that they should be able to see objects very near ; and as they soar high in the air, while their food is upon the ground, it is also requisite that they should be able to see afar off. Divine Wisdom has met these two extreme cases by the peculiar formation of the eyes of birds. The fact, accordingly, is, that two ‘peculiarities are found in the eyes of birds, both tending to facilitate the change upon which the adjustment of the eye to different distances depends. The one is a bony, yet, in most species, a flexible * Natural Theology. ORGANIZED NATURE. 85 THE EYES OF BIRDS SUITED TO THEIR HABITS. rim or hoop, surrounding the broadest part of the eye; which, confining the action of the muscles to that part, increases the effect of their lateral pressure upon the orb, by which pressure its axis is elongated for the purpose of looking at very near objects. The other is an additional muscle, called the mar- supium, to draw, on occasion, the crystalline lens back, and so fit the same eye for the viewing of very distant objects. By these means the eyes of birds can pass from one extreme to another of their scale of adjustment, with more ease and readiness than the eyes of other animals.° Du Hamel tells us (says Derham) of a singular conformity in the cormorant’s eye; and that is, that the crystalline is globous, as in fishes, to enable it to see and pursue its prey under water, which it does with wonderful swiftness for a long time. Birds obtain rueir Foop from various sources, and at various times; some by day-light, others in the dusk of the evening, or in the dark; some in the air, some on the earth, and some under the water, In all, the eye is essentially necessary. But no one uniform and regular structure of that organ would meet all these cases. The eye of the eagle would not answer the necessities of the owl; the eye of the owl would not suit the cormorant ; and though the same great and essential principles are found in rt ee Cae tater et * Nat. Theol, Physico-Theol, 86 ORGANIZED NATURE. LEGS, NECKS, AND BILLS OF BIRDS. = all, yet a peculiarity is communicated to each, different from all the rest, and exactly suited to its necessities. The infinite wisdom of God is alone equal to such an adaptation of mechanism to this diversity of circumstances. There are some. other peculiarities in the for- mation of birds which discover the same wisdom in their general structure; these I shall mention with brevity.—Many of the feathered tribe collect their food from brooks and ponds. These are generally supplied with long legs suitable for wading: but long legs render long necks necessary, without which it would be very difficult for them to obtain their food; and hence we find that those which have long legs have also long'necks ; though not the contrary, because there was not the same necessity. Others secure their food by swimming and diving. These are provided with membranes, extending from toe to toe, forming what we call the web foot, which is peculiarly serviceable in both the above-named operations. The formation of the Bruxs of birds is also deserv- ing attention. Those which feed upon grains of corn, and other minute particles, have their bills small and pointed. In those which feed on flesh, they are strong and hooked. In water-fowls they are broad, and often long, adapted to the taking in of a con- siderable quantity of water, and separating from it that which is nutritious. And in all these cases they ORGANIZED NATURE. 87 eran a > SR GIZZARDS OF BIRDS—CURIOUS EXPERIMENTS. are supplied with delicate nerves, to enable them to select their food with the utmost certainty. As there is a peculiar mechanism in those birds which feed on seeds, for decomposing and digesting their food, it is necessary that I should: mention it here. The food is swallowed into the crop, where it is moistened by a certain juice fit for the purpose : it isthen communicated to the gizzard, a kind of stomach composed of strong muscles, by the working of which, assisted by sand and pebbles, which are swallowed for the purpose, the food is ground small as between two mill-stones; from this apparatus it is discharged into the entrails, where it is further at- tenuated, and rendered fit for the formation of new blood. ‘This contrivance is rendered necessary on the one hand, by the nature of the food on which this description of birds feed; and on the other, by their want of teeth, and the means of mastication in their mouths, with which most other animals are provided. ~Reaumur and Spatanzanti tried a number of singular and curious experiments on some birds of this description, in order to ascertain the power of their digestive organs. ‘Tin tubes, containing grains of corn, were put into the stomachs of turkeys, and allowed to continue there a considerable time, when they were found to be broken, crushed, or distorted, in a most singular manner. ‘The stomach of a cock broke off the angles of a piece of rough jagged glass, in the course of twenty-four hours. A ball of lead was 88 ORGANIZED NATURE. SURPRISING POWER OF THE DIGESTIVE -ORGANS. covered with twelve sharp-pointed tin needles, pro- jecting about a quarter of an inch from the surface of the ball; the whole, covered with paper, was forced down the throat of a turkey. After remain- ing a day and a half in the stomach of the animal, all the needles were seen broken off, and two only could be found. Twelve small lancets, such as were used in the dissecting of small animals, sharp at. the points and edges, were inserted also in a ball of lead, and given toa turkey cock. After eight hours, the stomach was opened, and it was found that all the lancets were broken off, Three of these lancets were discovered in the intestines, pointless, and mixed with the excrements; the other nine were missing. What appears very astonishing is, that in none of these ex- periments was the stomach or the gizzard of the animal ‘in the least lacerated or injured, or its health impaired. It may be observed here, that rapacious and fierce birds increase their species but very slowly, seldom producing more than two or three young ones in the course of the breeding season; while those of a more innocent and inoffensive kind increase rapidly. Were it the reverse, the latter would soon be destroyed by the former, and would become terrible even to the human race. It may also be remarked, that birds of prey never go in flocks, but only in pairs, er alone. Were they to herd together as rooks, armed as they are with strong beaks and sharp claws, and were their fierce dispositions aggravated by hunger, they might ORGANIZED NATURE. 89 THE INSTINCTS OF BIRDS.~NESTS. eeeeeeEoEeEeEeooeeee—eEeEeEEoEeeeeoeeeeeeeoeeeEEE commit great depredations upon the rest of the animal creation. The Instincts of this class of animals are truly astonishing. These instincts direct them in all things necessary for their welfare. Instinct directs in their preservation. ‘Those birds which live upon plunder, as the rook, seem to be aware of their consequent danger. Hence they generally go in flocks, and while they are gathering the grain which has been sown, one of them is placed as a watch-bird upon some neighbouring tree, to give the signal on the approach of danger, which is instantly obeyed, and they make their escape. Instinct directs them in finding food. It is most observable in those birds which emigrate from place to place, and often from one country to another very remote. For when the season is advancing which will prevent them from obtaining their food in one place, they direct their flight with absolute certainty to another, in which they are sure to find it. Instinct directs in the building of their Nests. Though they have received no instructions where to build them, nor what materials to employ, nor how to arrange them, nor when to commence these curious operations, yet one generation follows another. with- out making the smallest alteration. In general, the nests of birds are built with an art so exquisite, that an exact imitation of them exceeds all the powers of human skill and industry. Their style of architec- 90 ORGANIZED NATURE. ee ture, the materials they employ, and the situations they select, are as various as the different species. Individuals of the same species, whatever regions of the globe they inhabit, collect the same materials, arrange and connect them in the same form, and make choice of similar situations for erecting their temporary habitations; for the nests of birds, those of the eagle kind excepted, after the young have come to maturity, are for ever abandoned by the parents. Many instances, illustrative of that surprising instinct which birds discover in building their nests, might be mentioned; but I shall specify the following only. An eagle's nest was found in the Peak of Derby- shire, which is thus described:—‘ It was made of great sticks, resting one end on the edge of a rock, the other on a birch tree. Upon these was a layer of rushes, and over them a layer of heath, and on the heath, rushes again; upon which lay a young one, and an addle egg; and by them, a lamb, a hare, and three heath-pouts. The nest was about two yards square, and had no hollow in it.” The nests of the common magpies are curious specimens of this sort of architecture. These nests are not open at the top. .They are covered with a singular dome composed of sharp thorns and briars, which reach all round to keep off the enemy, and to protect the eggs and-the young. Two openings are Jeft at the opposite sides of the nest, both for the .

These openings are too small to admit the entrance of birds larger than them- selves; and those which are of the same size, or smaller, in general they can successfully oppose, should they risk an unjust attack. In countries infested by monkeys, many birds suspend their nests upon slender twigs; and by this ingenious device, elude the rapacity of their enemies. This is the more remarkable, as these birds build their nests in the clefts of trees, in places where they are not in danger. In hot climates, says Mr. Pennant, the brute creation are more at enmity with one another than they are in other climates; and the birds are obliged to exert an unusual artifice in placing their little broods out of the reach of an invader. Each aims at the same end, though each by different means ; some form their hanging nests in shape of a purse, deep, and open at the top; others, with a hole in the side; and others, still more cautious, with an entrance at the very bottom, forming their lodge near the summit. Mr. Pennant then gives the following description of the manner in which the Taytor Brrp makes its nest:—“‘ It will not trust its nest,” says he, ‘even to the extremity of a slender twig, but makes one more advance to safety by fixing it to the leaf itself. It picks up a dead leaf, and, surprising to relate, sews it to the side of a living one, its slender 92 ORGANIZED NATURE. CARE OF BIRDS OVER THEIR EGGS AND YOUNG, a bill being its needle, and its thread some fine fibres, the lining, feathers, gossomer, and down. — Its eggs are white, and the colour of the bird light yellow; its length three inches; its weight only three-six- teenths of an ounce; so that the materials of the nest, and its own size, are not likely to draw down a habitation that depends on so slight a tenure.”€ Instinct directs in all necessary attention to their Eces. When they have deposited them in the nest which they have carefully adjusted for that purpose, they patiently sit over them during the necessary period, till they are hatched. When this is done they brood over their young by night to keep them from the chilling cold and dews; and in the morning, at break of day, the parent bird sets off in haste to collect the food suitable to their weak digestion, and almost starve themselves to feed their young. At the proper time the young are taught to fly and make provision for themselves, when they are forsaken by their parents, and no more regarded than absolute strangers. But by what means could these different objects be attained were this mysterious something, which we call Instincr, obliterated? Here are purposes to be accomplished requiring incomparable skill; and a principle is communicated by which they are infallibly obtained; and when this is done, the principle no longer operates, but appears to lie dormant till the BP rien tree pe prea ee mL 1! ae ee * See Pennant’s Indian Zoology.

A variety of instances might be adduced to show with what admirable skill individuals of this tribe are formed for peculiar modes of life; but I shall mention only one, by way of confirming and illustrating the former remarks. The structure of the Woop-PECKER is deserving of our notice. Its food is generally in or under the bark of trees. It has therefore feet and claws which enable it to fix itself upon the stems of trees of all dimensions, and in all positions, perpen- dicular, horizontal, or oblique, and to move along them without danger of falling. In order to this, two of its toes are disposed forward, and two back- ward. Its tail assists also in the pursuit of its food. Placing itself on the perpendicular stems of trees, it would be in danger of falling backwards; but the feathers of its tail are remarkably strong, which it places against the tree, and is by that means enabled to remain in the same position for a considerable time. “Their tongue,” says Ray, speaking of these birds, “they can shoot forth to a very great length, ending in a sharp stiff bony rib, dented on each side; and at pleasure thrust it deep into the holes, clefts, and cran- nies of trees, to stab and draw out insects lurking there ; as also into ant-hills, to strike and fetch out the ants and their eggs.”" Derham informs us, “ that their * Ray, on Creation. 94 ORGANIZED NATURE.

As it makes its nest in holes in the stems of trees which it excavates for itself, it is necessary that its bill should be formed for such hard labour. It is so in fact. It is hard, strong, and made like a wedge; and a ridge runs along the top of it, which greatly adds to its strength. Various ends are to be accomplished ;—and what a curious apparatus of means is provided, all the parts of which are most wisely adapted. | INSECTS. Amongst, those animals which are formed for living in or flying through the air, we may rank the various tribes of winged insects,! the general structure of which I shall now consider.—Their form is suited to passing through the air.

In these species which have no bones, but whose bodies consist of such a succession of rings curiously incased into each other, there is a power of contracting and dilating them; thus all the movements of this kind are performed. The head, in some species, changes its form every moment. It contracts or dilates, appears or disappears, at the . pleasure of the animal. These motions are permitted by the flexibility of the members, or coverings of the head. In other species, the form of the head is per- manent, owing to the hardness of the coverings, which are scaly or crustaceous, and approaches nearer to that of the more perfect animals." — As perspiration is essential to the preservation of animal life, and so hard a substance will not admit of this process, insects are provided with holes on their sides, which serve at once for perspiration and breath- ing. ‘Their bodies are covered all over with hairs, and many of them are decked with the most beautiful appearances, which, when viewed through the micro- scope, surpass in splendour the finest works of art, set with the most costly jewels.

The wings of some are constantly extended; such insects are almost perpetually flying about.—Those of others are supplied with joints for folding them up close to their bodies. Insects of this description live principally upon the ground, where their wings are more exposed to danger, from which they are defended by another kind of wings (elytra) which — serve not for flying, but merely for covering and defence. These elytra resemble leather, of a hard and solid nature, and are often of a beautiful colour, as in the lady-bird. Their outer surface is convex, to keep off wet; the inner surface is concave, fitted to the shape of their body, and the protuberance occa- sioned by the folding up of the wings. At first sight, indeed, these insects do not appear to have wings. The Oreans or Sient, with which insects are endowed, are peculiar to themselves, but admirably adapted to their necessities. The external covering of their eyes is hard and transparent, like glass. They consist, for the most part, of one lens only ; but in those of the butterfly, and many of the beetles, they are numerous.

Some of them have four, as the phalangium ; others, as the ‘spder and scorpion, have eight eyes. In a few insects, the eyes are smooth; in all the others, they are hemispherical, and consist of many thousand dis- tinct lenses. The eyes are absolutely immoveable : but this defect is supplied by the vast number of lenses, which, *from the diversity of their positions, are capable of viewing objects in every direction.

The Movurus of many insects are drawn. out to a rigid point, at the extremity of a most curious (ROsTRUM) proboscis, which is something like that of the elephant.

Can any mechanism be plainer than this is; or surpass this ?”* The mouths of many insects are of another description; strong, bony, and sharp, adapted to secure their prey, and tear it in pieces. The mouths of all insects are exactly adapted to the food on which they subsist, and the difficulties of obtaining it; and when procured, to the preparing of it for digestion. The structure of the mouth of the Gwar is deserving of attention here. It is one of the greatest curiosities in nature, and affords an astonishing dis- play of mechanism, though so exceedingly minute, that the most powerful microscope can scarcely render its extremity visible. It is a trunk or case composed of long scales, which the insect carries under its throat. At about two-thirds of its extent, there is an orifice through which it launches four darts, and nen I NS I Lo io Benicio toyed, " Natural Theology. H 2 100 ORGANIZED NATURE. THE PROBOSCIS OF THE BUTTERFLY. then draws. them into their quiver. One of these darts, however minute, is a case to the other three, which are there sheathed in a long groove, and have their sides sharpened like fine swords. ‘They are likewise barbed, or thick-set with cutting teeth towards the point, which is a little hooked, and remarkably fine. When these weapons are darted into the flesh of animals, the capillary vessels are wounded, and afford to the insect its desired food. But. if it meets with its food in a liquid state, it draws it up through the proboscis without ejecting its curious lancets. If, however, any thing resist, it throws out the Jancets, and then draws them into the scabbard, which it then applies to the orifice of the wound.° | | In Burrerrures, the proboscis is situated pre- cisely between the two eyes. Though some of them exceed three inches in length, they occupy but a small space. When a butterfly is not in quest of food, this proboscis is rolled up in a spiral form, similar to that of a watch-spring, each successive ring covering the one which precedes. The sub- stance of the proboscis has some resemblance to that of horn. It tapers from the base to the extremity. It is composed of two similar and equal parts, each of which is concave, and, when joined, form three distinct tubes. It is probable that these ° See Spec. de la Nat. from Leuwenhoek. ORGANIZED NATURE. 101 THE LEGS AND FEET OF INSECTS. tubes enable the animals to extract the juices of plants, to conduct air into their bodies, and. to convey the sensation of smelling. Hence the pro- boscis of insects is an instrument which serves them for a mouth, a nose, anda wind-pipe.? The Lees and Freer of insects are adapted to their roving mode of life. In the pursuit of their food, they are called into all positions ;—sometimes they run up and down smooth perpendicular bodies; at other times horizontally with their backs down- wards ; as, for instance, on the ceilings of rooms. Most insects have six or more legs, terminated by different kinds of feet, to meet these various ex- igencies. Some have sharp claws, by which they lay hold of soft substances; and other feet, in the same insect, are supplied with a sort of palms, to fasten upon smooth surfaces where hooks or claws would be of no service. All the families of hydro- canthari, notonecti, &c. have their hindmost legs _made very nicely, with flat commodious joints, and bristles on each side towards the end, serving for oars to swim; and those near the body are two stiff spikes, to enable them to walk when occasion requires.’ A certain fly, with six feet, has the two extreme pairs terminated by a kind of brushes, with which it dresses the anterior, or posterior part of its body." Grasshoppers and crickets have ’ See Smellie. 4See Derham, " St. Pierre, 102 ORGANIZED NATURE. THE STINGS OF INSECTS. strong thighs and slender legs, by the muscular power of which they will leap a considerable dis- tance. | Many insects are supplied with Stines, which are weapons both offensive and defensive. Though Derham, Ray, and all attentive naturalists have described them, Paley’s account of them, with their uses and relations, is the most complete and satisfactory: I shall therefore insert it here in his own words. Respecting the stings of insects, he observes :—“ The sharpness to which the point in all of them is wrought; the temper and firmness of the substance of which it is composed ; the strength of the muscles by which it is darted out, compared with the smallness and weakness of the insect, and with the soft and friable texture of the rest of the body, are properties of the sting to be noticed, and not a little to be admired. ‘The sting of a bee will pierce through a goat-skin glove. It penetrates the human flesh more, readily than the finest point of a needle. The action of the sting affords an example of the union of chemistry and mechanism, such as, if it be not a proof of contrivance, nothing is. First, as to the chemistry: how highly con- centrated must be the venom, which in so small a quantity can produce such powerful effects! And in the bee we may observe, that this venom is made from honey, the only food of the insect, but the last material from which I should have expected ? ORGANIZED NATURE. 103 THE STINGS OF INSECTS. that an exalted poison could, by any process of digestion whatsoever, have been prepared. In the next place, with respect to the mechanism, the sting is not a simple, but a compound instrument. The visible sting, though drawn to a point exquisitely sharp, is in strictness only a sheath; for near to the extremity may be perceived, by the microscope, two minute orifices, from which orifices, in the act of stinging, and, as it should seem, after the point of the main sting has buried itself in the flesh, are _ launched out two subtile rays, which may be called the true or proper stings, as being those through which the poison is infused into the puncture already made by the exterior sting. I have said that che- mistry and mechanism are here united; by which observation I mean, that all this machinery would have been useless, if a supply of poison, intense in quality, in proportion to the smallness of the drop, had not been furnished to it by the che- mical elaboration which was carried on in the insect’s body: and that, on the other hand, the poison, the result of this process, could not have attained its effect, or reached its enemy, if, when it was collected at the extremity of the abdomen, it had not found: there a machinery fitted to con- duct it to the external situations in which it was to operate; viz. an awl to bore a hole, and a syringe to inject the fluid. Yet these attributes, though combined in their action, are independent in their 104 ORGANIZED NATURE. origin: the yenom does not breed the sting; nor does the sting concoct the venom.” * | From the same able Writer, I shall quote a description of an instrument with which many insects are provided, for the purpose of depositing _ their eggs in suitable situations; an instrument of sur- prising curiosity. _It is “The Awx, or borer, fixed at the tails of various species of flies; and with | which they pierce, in some cases, plants; in others, wood ; in others, the skin and flesh of animals ; in others, the coat of the chrysalis of insects of a different species from their own; and in others, even lime, mortar, and stone. I need not add, that having pierced the substance, they deposit their eggs in the hole. The descriptions which naturalists give of this organ are such as the following: It is a sharp-pointed instrument, which, in its inactive state, lies concealed in the extremity of the abdomen, and _ which the animal draws out at pleasure, for the purpose of making a puncture in the leaves, stem, or bark of the particular plant, which is suited to the nourishment of its young. Ina sheath, which divides and opens whenever the organ is used, there is inclosed a compact, solid, and dentated stem, along which runs a gutter, or groove; by which groove, after the punctration is effected, the egg, assisted in some cases by a peristaltic motion, gee ditie geod) te yt ie ee * Nat, Theol.

In:the Cestrum, or Gap-r_y, the wimble draws out like the pieces of a spy-glass; the last piece is armed with three hooks, and is able to bore through the hide of an ox.” ‘The description which I have offered. applies only to the more perfect insects; there are others that appear to want many of these parts, and seem to be destitute of those organs which we are in the habit of thinking essential to life. Some want eyes, ears, brain, and nostrils. Others have an acute sense of smelling, though we know not the form or situation of the organ. This inferior description. of insects have no internal lungs, but. receive air by lateral pores, and sometimes by long tubes which protrude from different parts of the body. Many insects have no heart, or general reservoir for the reception and propulsion of the blood... But we discover, by the microscope, that their blood. cir- culates by the pulsation of arteries, and that their different fluids are secreted by glands." Having described the general structure of insects so far as the nature of my plan would permit, I shall now notice another peculiarity relative to them, which is calculated to excite our astonishment. It is their Mzramorpuosis. Infinite Wisdom does not at all times complete its designs in the first * See also Spec. de la Nat, * Smellie, 106 ORGANIZED NATURE. METAMORPHOSIS OF. INSECTS, formation of objects. It often conducts them through a curious series of changes, each of which appears, at first sight, to be the ultimate design ; but which, in fact, is only to make preparation for a superior mode of existence. This is remarkable in the me- tamorphosis of insects. But there is no real trans- mutation. Most of those members, which at last become visible to the eye, exist at the beginning, artificially complicated together, and covered with membranes and tunics, which are afterwards stripped off and laid aside.” It is the oviparous insects which are subject to these changes. In their perfect state they lay their eggs. And so powerful is the instinct with which they are endowed for raising their offspring, that they always deposit their eggs in the most favourable situation for security, m con- nexion with a provision of food for the young insect as soon as it is hatched. The eggs of insects are remarkable for their different figure and colour, and for the peculiar regularity and exactness with which they are frequently placed. We sometimes find a sort of eggs cemented round the twig of a sloe- tree, or damson-tree, as if fastened there by art, and arranged merely for the sake of beauty. ‘There is an inconceivable variety in the eggs of insects, and they are deposited on all sorts of bodies, as well as in water, on leaves, in the bark and wood of “ Bentley, on Atheism. ORGANIZED NATURE. | 107 METAMORPHOSIS OF INSECTS. trees, in the cavities of stones, and in the skins of animals.* Let us now consider the changes or metamorphoses of insects, from the egg to their perfect state. Insects change first from the (ovum) egg into the (Larva) caterpillar or maggot. In this state the insect is ‘masked, having its true appearance concealed. Under this mask, the entire insect, such as it afterwards appears when perfect, lies hidden, enveloped only in its tender wings, and putting on a soft and pulpy appearance, insomuch that SwAMMERDAM was able to demonstrate the existence of the butterfly with its wings in a caterpillar, though it bore but a faint resemblance to its future perfection. The insect therefore, in this state, undergoes no other alteration but the change of its skin. 9 When it has continued a certain time in this con- dition, it is changed into the (pupa) chrysalis; in this state the insect is covered over with a sort of thin shell or skin, and it has an appearance essentially dif- ferent from its former one. The chrysalis is connected by fine threads, which it spun while in its former State, to some substance or other, where it remains secure while thus helpless and motionless. It now requires no food. After remaining some time in this state, insects arrive at the (imago) fly, or perfect state. * Baker, on the Microscope. ” Encyclop, Brit.—Entomology. 108 - ORGANIZED NATURE. METAMORPHOSIS OF THE GNAT. Now their wings are unfolded, covered with their beautiful plumage; the antenne, the proboscis, the legs, and all the curious apparatus essential to the perfect insect, is developed, and it is able to propagate its species. ) I shall here illustrate this curious process in the instance of the Gnart. It lays its eggs upon some substance in the water, as the branch of a tree. When by the heat of the sun the eggs are hatched, the maggots descend to the bottom, and by means of the glutinous matter of the spawn, which they take along with them, they fasten themselves to stones, or other bodies, and there make themselves little cells, which they use at pleasure, until they arrive at a more mature state, when they become red worms, with something analogous to fins, and are able to swim about in pursuit of food. The insect has now a mouth and stomach accommodated to food; though in its chrysalis state it has no such organs, as it lives without food. In the state at which it has now arrived, its body is entirely changed; it has a club-head (in which the head, thorax, and wings of the gnat are all enclosed) a slender alvus, and a neat finny tail standing at right angles with the body, quite different to what it was before. It no longer swims by curvations, or twisting its body first one way and then another, as formerly in its worm state, but by rapid and brisk jerks, just the contrary way. In a short time, how- ever, it arrives at its gnat-state, when it has no finny ORGANIZED NATURE. 7 109 SS THE CARE OF INSECTS OVER THEIR YOUNG. tail, no club-head; it has now a most curious pro- boscis, or well-made spear, to wound and suck the blood of animals; wings, and all the necessary appa- ratus for living in the air, as before it had for residing in the water.’ In all these different states, it assumes appearances as different from each other as a worm is from a fish, or a fish from a flying animal. There are no insects, except those of the aptera class, but what are continually undergoing some such surprising transformation. In the Propacarion of their species, insects are singularly careful. In some,* the male and female discover equal attention to their eggs. When the female has laid her eggs in a little ball of dung, the male, with his feet, which are axiform, assists the female to roll it to some suitable place. In others,” it is observable that the female has no sooner brought forth her young, than she is devoured by it. Another® kills the caterpillar of the moth, then buries it in the earth, and there deposits her eggs in it. Nor can we behold without admiration the same species (of aphis) which. was viviparous in the summer, become oviparous in the autumn."

THE TREE BEE—THE SOLITARY WASP, ee I once collected a number of Curysaxips of the garden caterpillar, for the purpose of observing the development of the insect. Among the rest, there was one which appeared to be dead. But on breaking it open, a swarm of small black flies issued from it, to the number of nearly a hundred, which immediately began to crawl and fly. No doubt, some insect had deposited its eggs in this chrysalis. Ray mentions a remarkable instinct in what he calls the Trex Bez, whose industry in making pro- vision for her young is singular. She first excavates round vaults in a decayed tree, of a considerable length. In these excavations she builds her cylin- drical nests, of pieces of rose or other leaves, which she shears off with her mouth, and joins together by some glutinous substance. ‘These cases she fills with an unpleasant pulpy substance, of a red colour. She makes her cells, and stores them with this provision before she has any young one hatched, or even an: egg laid. And on the top of this substance she lays one egg, and then closes up the vessel with a cover of leaves. ‘The enclosed: ege soon becomes a maggot, which feeds on this provision till it arrives at its full growth, when it changes into a chrysalis, and then becomes a bee.° The Sorirary Wasp digs holes in the sand, in each of which she deposits an egg. She then collects (ete eles lat Rie el ol AT) ae le * Ray on Creation. Encyclop. Brit.—Jnstinct.: . ORGANIZED NATURE. 111 Se = : eenranuneeemmaanimene . . 4 THE SPIDER—POLITICAL ECONOMY OF BEES. Se a few small green worms, which she rolls up in a circular form, and fixes in the hole in such a manner that they cannot move. ‘Thus, when the wasp-worm is hatched, it is amply provided with the food which nature has destined for its support. The green worms are devoured in succession ; and the number deposited is exactly proportioned to the time necessary for the growth and transformation of the wasp-worm into a fly; when it issues from the hole, and is capable of procuring its own nourishment. This instinct of the parent wasp is the more remarkable, because she feeds not upon flesh herself. The common SprpER weaves a bag of surprising strength, in which she deposits her eggs, closes it up with the utmost care, and hangs it in a place the most secure from birds, or carries it along with her, either upon her back or under her belly, till they are hatched. The domestic and potiricaL economy (if I «may so term it) of certain insects is truly surprising. That of bees has been often described, of which I shall offer only a short account. They usually form a colony of eighteen or twenty thousand in the same hive; and though so great a number is together in so small a compass, they are under admirable discipline. A hive of bees may be considered as a monarchy, under the government of one bee, called the queen, to whom the rest manifest the sincerest attachment and affection. There is never more than one queen. in the same hive; and if she be destroyed, the utmost 112 ORGANIZED NATURE. THE CELLS OF HONEY COMBS. ait confusion instantly follows; the bees leave off working, feed on the honey which has been collected, forsake the hive, and pine away unless another queen is found to supply her place. In building their cells, bees discover surprising instinctive accuracy ; in this employment the neuters are alone engaged. When they begin to work, they divide themselves into four companies; one of which roves in the fields in search of materials; an- other employs itself in laying out the bottom and partitions of their cells; a third makes the inside smooth from the corners and the angles; and the fourth company brings food for the rest, or relieves those who return with their respective burdens. But the companies often change their employments with each other. 7 | The best possible shape is fixed on for their cells, at once to make the most of their room, and to give to each other the greatest strength and support. ‘This- shape is HEXAGONAL; by which no room jis lost, and the circumference of one cell makes part of the circumferences of those contiguous to it. They make the partitions of their cells remarkably thin, yet they are so constructed that the solidity may compensate for the scantiness of the materials. The parts most exposed to injury are the entrances of the cells. These the bees take care to strengthen by adding quite round the circumference of the apertures a fillet of wax, by which means the entrance is three or four times ORGANIZED NATURE. 113 | STRUCTURE OF HONEY-COMBS. ae Ss thicker than the sides: and they are strengthened at the bottom by the angle formed by the bottom of three cells falling in the middle of an opposite cell. The bottom of the cells is not flat, as might at first sight appear. In each cell it is composed of three planes which meet in a centre; but this centre is not in a flat surface, but concave. The combs lie parallel to each other; and there is left between every one of them a space which serves as a street, broad enough for two bees to pass by each © other. ‘There are holes also which go quite through the combs, and serve as lanes for the bees to pass from one comb to another, without being obliged to go a considerable distance round. | When the cells are built, some bees go about beating them with their wings and the posterior parts of their bodies, probably to give the materials all possible solidity; others are employed in polishing and perfecting them. This operation is performed by their talons, taking off every thing that is rough and uneven. The cells are for the reception of the honey, in which it is sealed up with wax when they are filled, or for the reception of the eggs of the queen bee, from which to raise up a young progeny. Here they often discover the most astonishing instinct. The female Bee, when the cells are not sufficiently numerous to receive her eggs, lays two or three in each cell. But a few days after when the cells are increased, the working bees remove all the super- I 1144 ORGANIZED NATURE. HONEY—BEES UNITE TO REPEL THEIR ENEMIES. numerary eggs, and deposit them in the newly-con- structed cells.‘ | The Honey is collected from the bottoms of flowers by the proboscis of the bee, through which it passes into a sort of stomach, where it undergoes a certain chemical change, and then is deposited in these receptacles. ‘The wax is made from the farina of flowers, which must also undergo a chemical process in another internal organ of the bee, before it becomes fit for use. In their economy, while they act with order and perfect harmony with each other, they are always united in repelling the attacks of their enemies, in which they do not fail to make use of their powerful weapons. If a snail or mouse intrude into the hive, the whole colony commences the attack, and stings the enemy to death, which, if too large to be removed, they immediately cover over with wax, to prevent the pestilential vapours of putrefaction from annoying them. In all these, and various other particulars which night be mentioned relative to these surprising insects, we must be struck with the wonderful adaptation of means to a proposed end. The end is, mutual sup- port. In order to this, there must be provision suit- able to the constitution of the animal, and also a winter store. ‘The bee is therefore provided with every _-— _ os 5 ie a + ‘ SMELLIE’S Philosophy of Nature. ; ORGANIZED NATURE. 1 DOMESTIC ECONOMY OF ANTS. requisite organ for collecting and preparing it for use;— with instinct to know where to find it, and at what season ;—with ability to form suitable apartments for its reception, and the best means of preserving it till demanded ;—with sagacity to act with propriety, as unforeseen but dangerous occurrences may require ;— and with inclinations to live in union and peace among themselves, where, amidst so great a number, a want of union and mutual forbearance must prove de- structive to the whole society. The whole affords a surprising demonstration of the Creator’s wisdom.’ The domestic economy of Aw'rs is little inferior to that of bees; but on this I shall not enlarge, mentioning only a few particulars. They form a sort of republic, governed by their own laws and politics. _ They make for themselves a kind of oblong city, with various streets and lanes, which terminate at different magazines of provisions. Some of the ants consolidate the earth, and prevent it from falling in, by a surface of glew, with which they incrust it. The common ants amass several splinters of wood, which they draw over the tops of their streets, and raise as rafters to _ Sustain the roofs; and across these they lay another rank of splinters’ and cover them with a heap of ‘dry rushes, grass, and straw, which they elevate with a double slope to turn the current of the water from $$$ * For a more particular account on this curious subject, see the word Bee, Encyclop.

SprpErs are exceedingly voracious animals, and devour vast numbers of flies by entangling them in those curious nets which they weave for the purpose, and suspend with great skill in situations where they are the most likely to succeed. A small spider often conquers a large fly which has more strength than itself. When the fly is. entangled in the spider’s web, the spider approaches with great caution after it has ceased fluttering; and standing at a convenient distance, extends one of its legs, and injuring the fly with its sharp claw, makes it again to flutter, and instantly retires with great speed to its cell, where it watches the process. It does the same again and again, till the strength of the fly is exhausted. It then makes a bold attack; and after — injuring it with its teeth, it places the dying fly at a short distance from its hinder parts, where, from the nipple from which it spins its web, it ejects many threads of this glutinous matter, and giving a rotatory motion to the fly by its hind legs, binds down its " Spec. de la Nat.

Spiders would soon increase in numbers so as to prove very injurious, were it not that they are greedily sought and devoured by birds, and especially by flies called IcunEUMons. The number of these is incon- ceivable. ‘They destroy not only spiders, but also vast multitudes of caterpillars and other insects. The Lipetia, or dragon-fly, devours almost every species of winged insects. It frequents marshy grounds, pools of water, and the margins of rivers, where insects abound most. Its appetite is so vora- cious, that it not only devours small flies, but even the large flesh-fly, moths, and butterflies of every descrip- tion. Some insects, as caterpillars, feed even upon their own species. in taking a retrospect of this part of animal and organic nature, we cannot but be filled with admi- ration and delight. In beholding these organized atoms, these floating machines, these diminutive forms, some of them only just visible to the eye as they pass, and yet supplied with the most curious and perfect means of subsistence, who does not wonder and adore? But how small a portion of these can we know! The greatest cause of wonder is beyond the reach of the most powerful magnifying glasses. Both the begin- nings and the ends of things, the least and the greatest, all conspire to baffle us; and which ever way we prosecute our inquiries, we still fall in with fresh sub- 118 ORGANIZED NATURE.

If the external organization be so wonderful, what must that internal economy be, which gives energy to the organs, and propagates motion in all directions, as from a common centre? How wisely are all the organs of insects adapted to their continuance in being! The shape of their bodies is suitable to the element through which they are so often to pass: their wings for con- veying them from place to place in quest of food or other objects: their legs and feet for their uneven and varying path, to meet every necessity of the case: their eyes for seeing objects in all directions with the greatest facility: their probosces and other shaped mouths for collecting food according to the circum- stances in which .it is generally found: their instru- ments for depositing their eggs in the most favourable situations: their stings for defending them against the foes to which they are commonly exposed: their solicitude and care in raising up a new race, which, by their own speedy death, will be rendered so neces- sary: their surprising instincts and political economy, with all that interior organization of muscles, blood- vessels, heart, lungs, stomach, and nerves, which is essentially necessary, and the whole comprehended . en a oe ee ‘See Wollaston’s Religion of Nature.

Having noticed winged animals, according to my proposed plan, I shall proceed to consider those whose residence is in the water. On examination we shall find that aquatic animals are formed on principles exactly adapted to the element in which they live, and to all their necessities. All nature teams with life: every element is crowded with inhabitants. We look on the smooth surface of a still lake, and we see nothing that appears to have life. But if we take up only one drop of it, and examine its contents by the help of the microscope, we shall find that this single drop contains millions of inhabitants. This assertion may, at first sight, appear hyperbolical and incredible; but, on exami- nation, we shall see that it is founded in matter of 120 | ORGANIZED NATURE.

Leuwenuorx de- clares that he has seen not fewer than eight millions two hundred and eighty thousand animalcula in one drop of water ; and affirms, that if a large grain of sand were broken into eight million equal parts, one of these would not exceed the size of one of those creatures. Yet, minute as they are, their organs are perfect; possessing all the essential parts of larger animals, both external and internal, though (as the above eminent naturalist remarks) they are in proportion to a mite, as a bee is toa horse. “ If these creatures. be so exceeding small (says Ray), what must we think of their muscles and other parts! Certain it is that the mechanism, by which nature performs the muscular motion, is exceeding small and curious ; and to the performance of every muscular motion, in larger animals at least, there are not fewer distinct parts concerned than many millions of millions, and these visible through a microscope.” Who by searching can find out God: who can find out the Almighty to perfection? But it is not in these diminutive animals that we can trace the Wisdom of the Creator in adapting organization to a proposed result. Arguing from analogy, we conclude, that this organization exists * Ray, on Creation. — Derham.— For a more particular description of animalcula, See Baker, on the Microscope, p. 68, &c. 3 ORGANIZED NATURE. 121 STRUCTURE OF SHELL-FISHES. as much in them as it does in others; but we must confine our attention to those animals whose organs are more apparent in their structure, and of which the use is more certain. Aquatic animals are sur- prisingly numerous, and astonishingly diversified in their structure; and yet the general principles of their economy are comparatively few, especially in their exterior form. I shall divide them into two classes :—the first class will comprehend those which are covered with shells; the second, those which are covered with scales, srprerce SHELL-FISH. Aquatic animals, which are covered with shells,' are very numerous, and surprisingly varied in their forms ; comprehending crabs, lobsters, oysters, muscles, and various others. Some of them are comparatively simple, and others more complex in their structure; but all have received a confor- mation suited to the element in which they exist, the dangers to which they are exposed, and _ their modes of living. Oysters and muscles do. not ' The terms Testaceous and Crustaceous are used by naturalists in describing animals covered with shells.

However, they are not so helpless. The Muscie, in particular, is pro- vided for meeting both these necessities, though in but a slight degree. It moves itself by means of its congue, a firm and strong substance, which it is able to extend an inch anda half beyond its shell. When it wants to move itself, it inserts the tip of this tongue in the sand; or in the cavities of the substance where it may happen to be, and then draws itself forward by its muscular contraction. When it comes to a suitable situation where it finds its food, by means of the same organ, it forms threads of glutinous matter with which it is pro- vided, one end of which it fastens to the ground, and keeps hold of the other. As one of these threads would be insufficient to enable it to with- stand the current of water, it forms many, and thus remains secure, as a ship at anchor. When the muscle wants to remove, it emits another juice which acts as a dissolvent upon the threads, and thus sets itself at liberty. What surprising mechanism! Though the Creator appears to have been sparing in the bestowment of members for action, yet one is granted whose structure meets every necessity. It is not only a tongue for its common purposes as such, but also a leg to assist the animal in its progress, and a mould to form and shape the threads i” lll ORGANIZED NATURE. | 123 SoS aS SR SR a SY CARP aSNSEarene ee , LOBSTERS=—-CAST THEIR SHELLS. requisite for her fastening. How much curious mechanism in so small a compass !™ The structure of the various species of crabs, lobsters, and shrimps, is more complicated and sur- prising. ‘They are covered with a strong and hard shell for defence. I have often viewed the lobster as one of the wonders of nature. Besides its legs for motion at the bottom of the sea, by means of its strong tail, it can throw itself backwards through the water with astonishing velocity, and to a considerable distance by one single stroke. It has two formidable claws, the one for holding itself fast by the rocks, or sea weeds, and the other is sharp for cutting its food. Its mouth is a most singular piece of mechanism, and worthy of close examination. Its teeth are in its stomach ; its eyes are lenticular and protuberant, placed at the termination of projected footstalks, for the purpose of seeing objects in all directions; but they are well protected by strong bony spikes,- which have a formidable appearance. Like other insects (for the lobster belongs to the order of insects called by naturalists apéera) it is supplied with long antenne, and palpi, and no doubt for the same purposes. When the shells of these creatures are formed they can grow no larger. But their increase in size is provided for by the faculty they possess of annually changing their shells.

In this tender and defenceless state, the animal hides itself in the holes of the rocks, as well to secure itself from the unnatural ferocity of its own species not in the same condition, as to avoid other enemies. In afew days it has a new covering suited to its enlarged body. During the time that the old shell is worn, a sort of stony concretion is formed in the body of the animal, from which it would seem that the new covering is produced, as it gradually decreases during that process, and when completed, it entirely disappears. Four of these stones have been remarked in the violet crab of the Bahama Islands ; they are found under its stomach, and gradually decrease, as in the former case, as the shell hardens, and when it comes to perfection, are found no longer, There is a small parasitic crab which, on account of some peculiarities,’ deserves distinct notice. It is called the Sorpirr, or Hermir Crab. It is only the fore part of this animal which is defended by a shell covering; its tail is naked, soft and tender, yet pro- vided with a sort of hook, by which it secures itself in its lodging. But though it is thus exposed, and has no provision of its own for security, so great is its sagacity, that it makes provision for itself, by taking refuge in the deserted shells of other animals, such as ORGANIZED NATURE. 125 onde THE NAUTILUS. the whelk. The shell is chosen according to the size of the animal, and is carried along with it as the snail carries its covering, into which, when danger ap- proaches, it retires with the utmost readiness. When its habitation becomes inconveniently small, it looks out for another more suitable. | It goes to the line of pebbles and shells formed by the highest wave on the beach, still however dragging its old incommodious habitation at its tail; unwilling to part with one shell, though a troublesome appendage, till it can find another more convenient. It stops at one shell, — and turning it, passes it by: it goes to another, and contemplates that for a while, and then slips its tail from its old habitation to try the new one; if it finds this to be inconvenient, it immediately returns to its old one again. In this manner it frequently changes, till at last it finds one light, roomy, and commodious; to this it adheres, though the shell be sometimes so large as to hide both its body and claws." Though the Creator has denied this little animal the natural means of security, he has bestowed upon it an instinc- tive faculty to make use of one, which, though artificial, is a good substitute. | There is a kind of Nauvritvus, called by Linnzus Argonauta, whose shell has but one cell; of. this animal Pliny affirms, that having lightened its shell "See CanceR—Encyclop.

VIOLET LAND-CRAB—ITS MIGRATIONS. by throwing out the water, it swims upon the surface of the water, extending a web of wonderful tenuity, and bending back two of its arms and rowing with the rest, makes a sail; and at length receiving the water, sinks again.° Like the above-mentioned crab, it in- habits a shell not its own. ‘These facts are well attested by many who have seen it in the act of swimming. In the warmer countries of Europe, and particu- larly in the tropical regions of Africa and America, is found the Viotet Lanp-Crap, which is remarkable for its annually migrating from the mountainous countries which it inhabits, to the sea. In the months of April and May, crabs of this description leave their holes and subterraneous retreats, and collect, and march in millions to the sea-shore. ‘The design in performing this journey is to deposit their spawn on the shores of the sea. They form themselves into three companies; the first company consists of the largest and strongest males, who march first like pioneers, to clear the way. The second company is composed of the females; these form the main body, and descend from the mountains in regular columns, fifty paces broad, and sometimes three miles in length, and so close together, that they cover the ground. In the next company, which may be considered as the rear guard, are all the straggling males and females, a mere undisciplined troop. ‘Thus formed, they pro- ° Darwin's Works. __...

However, when they come to a river, they are obliged to wind along the course of its stream. They travel chiefly during the night, unless it should rain in the day-time, when they proceed in a slow and regular manner. Should the sun shine, they halt till evening, and then resume their march. If alarmed, they retreat backward in great disorder, and erect their nippers in a threatening posture, and make such a noise as to intimidate their enemies. ‘These journeys sometimes cost them three - months of great exertion. Having deposited their spawn on the sea-shore, they march back again to the mountains. PP PL IL OL FISHES, On the structure of Fishes I shall offer a few remarks, illustrative of the wisdom of God in adapting their organization to the element in which they live. In passing through a fluid element, it is obvious that the resistance must be in the ratio of its density, which, in the case of water, is much greater than itis in air. If fishes have received a suitable organi- zation, we may expect to find in them the best shape for avoiding the resistance of this obstacle, and a muscular strength sufficient to overcome that which 128 ORGANIZED NATURE. ue) SHAPE OF FISHES SUITED TO THEIR ELEMENT. cannot be avoided. If we carry this supposition along with us in examining the structure of fishes, we shall find it at once confirmed and illustrated, especially in those which move with great velocity. They are long and slender; their heads terminating in an acute angle, to cleave the water and make way for the body, which is tapering from the thorax towards the tail. It is admitted by naturalists, that this shape is preferable to all others. But besides their suitable shape, for moving with facility through so dense a medium as water, it is necessary that the skin of fishes should be smooth and free from all protuberances. ‘This is also remarkably the fact : besides the scales, which lie folded one over another from the head to the tail, and which are uncommonly smooth, fishes are covered over with a slimy mucus, which is admirably adapted to destroy friction and the consequent resistance. ‘These scales and _ this mucus are probably subservient to another purpose ; that is, to keep the pressure of the water at a distance from the capillary vessels of the skin, whose action is essential to the important process of perspiration. It is generally agreed among naturalists, that the motion of the fish is produced principally by the action of the tail; the pectoral and other fins serving only to keep it in its proper position on its belly, and to assist in rising and sinking. It is necessary, therefore, that the muscular strength of the tail should be great, in order to produce any: ; ORGANIZED NATURE. $29 Sree THE AiR BLADDER OF FISHES, = SAAD.

Tor the muscular power in the tail of eyen a small fish, as, for instance, the trout or the herring, is truly astonishing; a strong man being scarcely able to hold it. —-HANDS. : strength and flexibility are possessed exactly equal to the necessity of the case. The feet are joined to the legs at the best conceivable point of union: not in the centre, nor at either extremity, but at a short distance from the hinder end. The greatest length of the feet being by this means in the direction of the face, man acquires a proper balance in his forward motion, and a more ready command of his steps as circumstances may demand. And the legs being placed towards the back part of the foot, a greater influence is obtained in front, by affording the back muscles and tendons the advantage of a lever. The extension of the heel beyond the leg is ne-+ cessary to keep the body from falling backward, and is well stayed by means of the muscles and tendons on the front of the foot. Here is a suitable contrivance for activity. A child’s learning to walk is its learning to balance itself upon its feet, and to keep its body in the centre of gravity, which is the position natural to it whilst it is motionless. When we want to walk’ or run, we throw our bodies beyond the centre of gravity, which obliges us to put our feet forward to preserve ourselves from falling. In all this there is far more cause for admiration than is generally supposed. THE HANDS. Our hands are a most singular contrivance, and afford an astonishing display of wise adaptation. ORGANIZED NATURE. __. 165 re a ey THE MECHANISM OF THE HANDS. They are joined to the arm by a curious mechanism, which gives them a motion half round, as if they moved upon a centre. Each hand is composed of twenty-seven bones, all differently shaped in some respects, and of various lengths. They are so articulated as, at the same time, to possess sur- prising strength, and great flexibility. It is won- derful, as Ray observes, that the tendons which bend the middle joints of the fingers should be perforated, to give passage to the tendons of .the muscles which draw the uppermost joints; and all are bound down close to the bone with strong fillets, lest they should start up and hinder the hand in its work, standing like so many bow strings. Had the hand been composed of one solid bone, it could have been subservient to'a few purposes only. But being separated into different -bones placed parallel to each other, every chain of bones divided into several joints, and every joint being supplied .with its proper tendons to bend it forward and backward, it is able to accommodate itself to bodies of all shapes, square, triangular, cylindrical, &c.. as may be necessary. The different lengths, as well as the various sizes of the fingers, are also of importance to the general purposes for which the hand is formed. And so great is the command which we have over these important members, that we can call one or all of our fingers into action at pleasure. . Neither do they all move in the same direction. One of these divisions, which we call the thumb, acts in a con- 166 ORGANIZED NATURE.

Our feet and legs afford us the means of motion; our eyes direct us in the way by which that motion is to be performed; but it is the hand which executes almost all the important duties of life. Were we to observe their movements with attention, and write a history of what they perform in one day only, we should be astonished at the variety, the different inflections of their parts, and the multiplicity of circumstances to which they had accommodated themselves. If our bodies be deprived of only one of these useful parts, they seem to lose half their importance; nay, if but a finger is gone, or but one single joint of a finger, we feel that we have sustained an irreparable loss. We never can sufficiently admire the wisdom and good- ness of God in bestowing upon us members so valuable, and of s0 vast importance both to our- selves and to one another: but because they are common and always seen, we seldom think of that intelligence which their formation discovers. The hands being placed at the extremity of the arms, and supplied with joints and muscles suited for moving them in all possible directions, is an- other proof of contrivance. Had the hands, formed as they are, been fixed on any other part of the bedy contiguous to each other, their usefulness must ORGANIZED NATURE, ‘167 Po nce eae 8 9 Ra ET SE LT TTS A NEA a EE RN ERT TT THE EYE. have been greatly circumscribed. | But situated at the extremity of the arms, they can be brought. toge- ther, or moved at the distance of five or six feet; they can seize objects of considerable magnitude, or such as are of the smallest size. SLII LS THE EYE. . The Eye is the next object which I shall consider in this amazing organic system. Its economy, its uses, its characteristic appearances in different persons, have always excited attention, and employed the curious inquirer. It is particularly in the eyes, says Buffon, that the -PAssions are painted, and most readily discovered. ‘The eye appears to belong to the soul more than any other organ; it seems to participate of all its emotions; the softest and most tender, as well as the most violent and tumultuous. There it not only receives, but it transmits, by sympathy, into the soul of the observer, all that secret. fire with which the mind. is avitated ; and thus does passion often become general... In short, the.eye is the lively index of the. mind, and forcibly speaks the language of intelligence.’ It is the structure of the eye which I intend to describe with all the brevity that is consistent with perspicuity. en ene ew Serpe --- ' Natural History, vol. LV. 168 = ORGANIZED NATURE. Se eS THE TUNICS OF THE EYE—CORNEA, , pp To give us a knowledge: of surrounding objects, is obviously the design of God in the formation of this curious organ. And it is found that every eye is a true optical instrument, on the ground of which light delineates, or rather paints in miniature the portrait of every object situated in the view of the spectator: and of all the subjects of observation which nature every where presents to us, it may justly be said of this organ, that there is none which more forcibly exhibits in its structure and adaptation the marks of Infinite Intelligence." It is provided with every mechanical prerequisite—for performng the offices of vision ; for adjusting itself to different circumstances ; and for preserving it from injury. The eye is so formed as to effect the othces of vision, or to convey to the brain an idea of surround- ing objects. I shall here describe the ball of the eye. It is composed of three tunics or coats, and three humours; itis nearly spherical, except on the anterior part, which is rather protuberant; as if a segment of a smaller globe were placed on the surface of a larger. Both parts are covered with a tunic which appears white and opaque as far as the edge of the protuberance, and is called the scLEroTica; that part of this tunic which covers the protuberance is denominated the cornea, and is perfectly trans- yigioe ls of bugis | lode gio out ee eit ase tly k Rér these and some other remarks on this subject I am indebted to Haiiy’s Natural Philosophy, translated by Olinthus Gregory, A.M; Adams's Lectures on Natural Philosophy; Encyclopedia, the words Anatomy and Opties.

Immediately under this tunic is found a transparent fluid, like water, which is therefore called the aqueous humour, and is of the same limpidness, specific gravity, and refractive power as water. It fills the interstice between the cornea and the pupil, and also the small space extending from the wvea} to the crystalline lens. It is included in a membrane so delicate that it cannot be made visible. - / In passing through the aqueous humour, before we reach the extent of it, we meet with the Iris, which is joined to, and seems to be “produced by, the choroides, another tunic immediately under the sclerotica; this continuing its course ‘nearly in the line of the circumference of the larger globe of the ‘eye, terminates in the iris, which is of course at some depth in the aqueous humour. ‘The regs: is ‘an opaque membrane of different colours im different persons; in some blue, in others grey, and in others hazel. The iris is an assemblage of muscular fibres ; some are orbicular, and ranged round the circum- ference of the pupil; others. direct, like so many radial lines. The use of the former is to contract the pupil in order to moderate the impression of too ‘strong a light; and of the latter to dilate it, that a greater number of rays of a faint light may be ad- “mitted.—By the pupil of the eye is meant that circular aperture which is surrounded by the iris. ) — ‘The uvEA is the posterior surface of the iris, and is of a. black colour. | 170 ORGANIZED NATURE. pe ne ny eg A a A THE CRYSTALLINE AND YEEREOUS HUMOURS. Beyond the pupil, and at the bottom. of the aqueous humour, is the crysTALLINE humour, which is shaped like a double convex glass, being a - ittlesmore convex on the back than on the fore-part, and is received into a corresponding concavity in the yitreous humour. In consistency it 1s somewhat like a hard jelly, becoming softer from the centre out- wards, and is as transparent as the purest crystal, from which circumstance it derives its name. It is formed of concentric plates or scales succeeding each other; and these scales are composed of fibres elegantly figured, and wound up in a stupendous manner, Leuteenhoek has computed that there are near two thousand laminz, or scales, in one crystalline; and that each of these is made up of a single fibre, or fine thread, running this way and that, in seyeral courses, and meeting im as many centres, yet never interfering with or crossing each other. ‘Ihe whole is included in a sort of capsule, or case, the fore-part of which is very thick and elastic; the hinder-part is thinner and softer. ,The use of the crystalline humour is to converge the rays, which pass through it from every visible object, to its focus at the bottom of the eye. At the back of the crystalline lies the yrrrEous, which is the third humour of the eye. It receives its name from its appearance which is like melted glass. It is neither so hard as the crystalline, nor so liquid as the aqueous humour, though the largest of all in quantity, fillmmg the whole orb of the eye, and giving it ORGANIZED NATURE, 171 —. THE RETINA. ~a globular shape.. It is much of the consistence of the white of an egg, and very little exceeds the specific eravity and refractive power of water. ‘The vitreous humour is contained in a very thin pellucid membrane‘ (tunica vitrea), which is concave at its fore-part to receive the crystalline lens: at this place its membrane divides into two, the one covering the cavity in which the lens lies, the other passing above, covering the fore- part of the crystalline humour, and thus forming a sort of sheath for it, called the capsula crystaflina. The fabric of the vitreous humour is cellular, the substance of it being divided by a very fine transparent membrane into cavities, or litthe membraneous com- partments containing a very transparent liquor. The third and last membrane of the eye is called the Retina, because it is spread like a net over the bottom of the eye. It is the thinnest and least solid of the three coats; being a fine expansion of the medullary part of the optic nerve. The convex side of it lines the choroides, the concave side covers. the surface of the vitreous humour, terminating where the choroides folds inwards. It is an essential: or- gan of vision; for on it the images of objects are represented, and their picture formed. ‘The whole of the choroides is opaque, by which means no light is allowed to enter into the eye, but what passes through the pupil. To render this opacity more perfect, and the chamber of the eye still darker, the posterior surface of this membrane is covered all over with a black mucus (pigmentum nigrum) which is i 5 ee ORGANIZED NATURE. THE EYE CONNECTED WITH THE BRAIN BY THE OPTIC NERVE. thinnest upon the concave side of the choroides, near the retina, and on the fore side of the iris; and thickest on the exterior side of the choroides, and the inner side of the uvea. | But all this amazing apparatus would be useless to us unless it had an immediate connexion with the sensorium. This connexion is formed by means of the OPTIC NERVES, which are considerable trunks, sepa- rated as they proceed from the brain, and afterwards’ united in a common point; when separating again, they pass out of the scull through a hole in the bottom of its orbit, a little inflected, of a figure somewhat round, but compressed, and are inserted into the globes of the eyes, not in the middle, but a little higher and nearer to the nose ; for if the nerve had been situated in the axis of the eye itself, then the middle of every object would have been invisible; and where all things else contribute to make us see best, we should not have seen at all. . The reason of this is, because our eyes are insensible at the part where the optic nerves enter. Hence they are wisely placed by the Divine Artist for this and other advantageous ‘purposes, not in the middle, but a little higher and nearer the nose.—-An artery runs through the optic nerve, goes straight through the vitreous humour, and spreads itself on the membrane that covers the posterior side of the crystalline. The design of this contrivance is, that we may form accurate ideas of surrounding objects. And it is found that by means of these different humours ORGANIZED NATURE. 173 HOW VISION IS EFFECTED, thus formed and arranged, aided by light, a picture’ ef surrounding objects is actually painted upon the retina, in the following manner.—As_ these three humours possess different refracting powers, the rays of light must suffer three refractions in passing through them. ‘The cornea is spherical; and for the purpose of taking in a greater quantity of light is somewhat prominent. Now parallel rays of light falling on the convex surface of the cornea will be made to converge. But the aqueous humour, being of about the same density with water, the rays by this first refraction would be made to converge to a point at twice the diameter of the convex surface: but this point is: considerably beyond the retina ; it is therefore neces- sary to vision that some other convex surface of greater density should be interposed to increase the converging of the rays. This is effected by the crystalline humour. Still, however, the rays would converge beyond the retina, were it not for the vitreous humour. ‘This being of a less refractive power than the former, and presenting a concave surface where the rays pass into it from the crystalline, they are still further refracted, and unite at the retina, on which a perfect image of the objects we look at is most distinctly represented.” | In considering ‘vision as being achieved by the means of an image formed at the bottom of the eye, says Paley, we can never reflect without wonder ™ See Gregory’s Economy of Nature. 174 ORGANIZED NATURE. OBJECTS PAINTED ON THE RETINA INVERTED. —- ee pits inate arecm a upon the smallness, yet correctness of the picture, the subtilty of the touch, the fineness of the lines. A landscape of five or six square leagues is brought into a space of half an inch in diameter, yet the multitude of objects which it contains, are all pre- served, are all discriminated in their magnitudes, positions, figures, colours. The prospect from Hampstead-hill is compressed into the compass of a sixpence, yet circumstantially represented. A stage-coach, travelling at its ordinary speed for half an hour, passes, in the eye, only over one twelfth of an inch, yet is this change of place in the image distinctly perceived throughout its whole progress; for it is only by means of that perception that the motion of the coach itself is made sensible to the eye. If any thing can abate our admiration of the small- ness of the visual tablet compared with the extent of vision, it is a reflection, which the view of nature leads us every hour to make, viz. that in the hands of the Creator, great and little are nothing.” Objects are painted upon the retina in an inverted position; and hence many have supposed that we actually see things in this position, and through habit learn to view them as they are. Others again, as intelligent as the former, conceive that, notwith- standing this fact, we see objects in their real position. After examining the subject on both sides, I fully acquiesce in this latter opinion. As we look at the * Natural Theology, ORGANIZED NATURE, 175 HOW IMAGES REACH THE MIND MYSTERIOUS, same. object with both eyes, some again have thought that we must see double, and that the power of habit _ and experience correets this error also. But this is much more philosophically accounted for by con- sidering, that the optic nerves of both eyes are united at a certain point, though they separate again. before they reach the brain. But though we find in the structure of this won- derful orb an organic disposition of parts that conveys the image of surrounding objects to the retina on principles which the science of optics very imperfectly imitates, yet how this image passes along the solid and opaque nerves to the brain, must be confessed a mystery which has never yet been, and probably never will be explained in the present state of man. What reason for astonishment is here! That materials such as those which compose the eye, and so essen tially different from any that we find in the rest of the system, should be so proportioned, so arranged, so connected, as with absolute infallibility to accom- plish an end, the most essential and important to animals, Can a being who possesses the scantiest share of intellect for one moment suppose that this is a mere fortuitous combination of atotig? Or, with a knowledge of the structure of the eye, cai he for one moment doubt either the existence of a God, or his wisdom? I know but of one dee scription of created existences which more excites my astonishment than the structure of ate eyed mean Atheists, . 176 ORGANIZED NATURE. <= - ae HOW THE EYE ADJUSTS ITSELF TO OBJECTS AT DIFFERENT DISTANCES. — Having shown that .the eye possesses every mechanical prerequisite for performing the office of vision, 1 proceed to describe that apparatus by which it is able to adjust itself to different circumstances. Those objects which come within the sphere of vision are in different situations, and at every point of obliquity—some horizontal, some more elevated, and others lower than the eye; some again on the right hand, and others to the left. If the eyes had been immoyeably fixed in their sockets, though the motion of the head might have directed the visual organ to the object, yet it would not have been with that cele- rity which circumstances frequently require. There- fore, besides the advantages which the eye derives from the movements and muscles of the head, it possesses additional conveniences from heing moveable in its own orbit. It is supplied with six muscles, so placed and connected with the ball of the eye as to direct the pupil to every point within the field of obser- yation.—To describe these muscles would be tedious. Besides;. objects, are. at different distances, and are consequently viewed under different angles. And though the same visual apparatus will enable us to see those which are afar off, as well as those which are near, yet a change must take place in the form of the humours of the eye, suited to the distance of the object, .to shorten or elongate the: focal distance. This, as it appears from some late experiments, is effected by the influence.which the muscles of the eye have upon the cornea, rendering it. more or less ORGANIZED NATURE, 177 HOW THE EYE ADJUSTS ITSELF TO DIFFERENT LIGHTS convex as circumstances require.. It appears that the cornea is composed of lainine which are elastic, capable of being elongated one-eleventh of its dia- meter, and contracted again to their former length by its own exertions. The four straight muscles of the eye are continued to the edge of the cornea, and inserted in its external lamina. From these experi- ments it appears that, in changing the focus of the eye from seeing with parallel rays to a near distance, there is a visible alteration produced in the ficure of the cornea which renders it more convex; and the alte- ration by which the cornea is brought back to its former state is equally visible.° In adjusting a tele- scope to objects at different distances much time is lost, but this adjustment of the eye is effected in a moment, without trouble, and in a manner perfectly insensible to us. Again; objects are seen in different degrees of light ;—from the faintness of twilight, to the effulgence of the meridian sun: and the eye is supplied with an instrument which enables it to meet every degree of difference. This instrument is the Iris, which; as it was before remarked, possesses a power of narrowing and enlarging the diameter of the pupil to admit more or fewer rays of light as the case may require. This affords essential service to vision: When the light is strong, or the visual object too luminous, we contract the pupil in order to intercept erect ae Lauer eee 110 CREE Oe) UO UE SE oe ° Philosophical Transactions for 1795, Part 1.

This aperture dilates also for viewing distant objects, and becomes narrower for such as are near. Yet under these different changes of the diameter of the pupil, it most exactly preserves its circular figure. From all this it appears that, under different cir- cumstances of vision, important changes must take place in the eye to render it useful to the end of its formation, and that it is supplied with all the powers which are necessary to these purposes ;—muscles, which at once direct the pupil to the object to be viewed; which produce a convexity in the cornea according to the: distance of the object, so that its image may fall exactly on the retina at its proper focal point; and which alter the diameter of the pupil according to the quantity of light which at the time exists;—and yet no confusion is observed, no difficulty felt.—W ho can sufficiently admire the bound- less wisdom which all this mechanism displays! But this astonishing machinery is exposed to ¢on- siderable danger, and frequent injury. Let us now notice that wisdom which appears in the means of its preservation. External dangers are provided against by the strong bony socket in: which it 1s placed, and which is particularly prominent where danger is the most probable, that is, on the upper part. -On the skin that covers these bones grows ORGANIZED NATURE. 179 USES OF THE EYELIDS. a. wary hair, which preserves the eye from dust and other inconveniences. As the cornea is constantly exposed to the action of the air, it is liable to become dry and parched, which would greatly injure its transparency, and consequently render the eye useless; it must therefore be kept in a state of humidity. Provision is made for this necessity by the Eyenrps, which are singularly contrived for answering this end, as well as affording a covering for defence, and a screen for excluding entirely the rays of light. The underside of this covering is supplied with vessels which dis- charge copiously a liquid exactly suited to the eye. This it disperses over all that part of its orb which is exposed; and whenever it becomes superabundant, it is discharged through an orifice which commences at the internal angle of the eye, and opens into the nose.—Further; the ball-of the eye is almost in per- petual motion ; but the destructive consequences of friction are prevented by the soft substance on which it moves. This is so remarkably smooth that, though the eye performs thousands of movements every day for seventy or eighty years, yet not the least injury is observable on its coats. If by any means the eye Is so far injured by accident as that the aqueous humour escapes from under the cornea, in a few days:it is replenished, though the vessels which perform this office have not yet been discovered. Thus we see that abundant provision is made for the preser- vation of this important faculty, from all .common dangers, — provision which displays a provident N 2 LSU ORGANIZED NATURE. tiated. aca nstek el ete el ncaa at mst PAAR HN OLE RACES ESTOS TS rem core STRUCTURE OF THE EAR. wisdom, and which long perpetuates to us a blessing of inestimable worth.’ binidie While we contemplate with just astonishment the wonderful organ of sight which is bestowed upon the creature, let us not forget the eye of Him whose sphere of vision is not confined to our contracted horizon, but at once includes a universe with all its objects ;- all the rational creation, with their every thought, and action, and intention ;—nay, all that has transpired, whatever is now projecting or executing, and the unnumbered events of futurity, are all under his immense survey.

Without this faculty, speech: were useless, and society would lose almost all its chartis. God has therefore bestowed on man an organ which is fitted to receive sounds, and placed him in an element adapted to convey them to it This element is air; which, while it answers a variety of other‘important purposes, is essential to the trans- yaission of sounds from one person to another. ‘This ORGANIZED NATURE. 181 a THE EXTERNAL EAR—DRUM OF THE EAR, element has already been described: it is the Ear itself whose structure I shall now attempt to explain. The ears of all animals appear to be constructed on the same general principles, though they differ in some unessential particulars, with a view to meet the exigences of their different habits and circumstances. It is the human ear which I shall now consider, but with all possible brevity: anatomical minuteness would lead me far beyond my design.? At the first glance we are struck with the suitable- ness of the form which the external part of the ear has received for the admission of sounds, which are pro- pagated in direct lines through the air, from the object that occasions them, The outward ear (concha) pre- sents a cavity somewhat like a funnel, of a carti- laginous substance, with various protuberances and cavities admirably adapted to the reception of sonorous undulations, and to condense and convey them inward along the cifcular tube which we discover at the bot+ tom, This tube (meatus auditorius) takes an indirect course towards the brain, gradually lessening its dia- meter till it comes to a fine thin membrane, (mem- brana, tympani) the drum of the ear, which is stretched across it, but out of sight. This membrane is carried over a heop of bone, which is nearly circular, and to which it is fastened. Its surface is not flat, but rather concave, its convex surface being inward.

It is supposed that the intention of this tube is to admit sounds from the mouth to the tympanum. | | Attached nearly to the centre of the convex sur- face of the membrana tympani, is a small bone, made something like a hammer, hence called MALLEUs, being larger at one end than at the other. It is the small end which is fastened to the tympanum. The larger extremity is attached to a second bone which bears some resemblance to an anvil, for this reason called the 1ncus, one of whose legs descends parallel to the malleus, and receives another little bone (os orbiculare) convex on one side, and flat on the other, and resting upon the srapEs. This bone (stapes) is so denominated from its bemg shaped like a stirrup: it has a hollow head which receives the iIncus where their junction is formed. ‘The oval basis of the stapes rests on the aperture of a corresponding figure, called the FENESTRA OVALIS, that conducts to the labyrinth, or innermost chamber of the ear, which is filled with real water. In the fenestra ovalis lie the auditory nerves, the ramifications of which float in the water in the labyrinth, and there receive the sound which is conyeyed to it. This aperture is closed by the stapes _ which has a part of auditory nerves spread over its basis.t The whole of this surprising mechanism, with .4 Derham. ORGANIZED NATURE: 183 HOW SOUNDS ARE CONVEYED TO THE BRAIN. its various tendons and muscles, is deposited in the cavity of the tympanum. ; Let us now see how this singular contrivance is adapted to the conveying of external sounds to the brain. The outward ear has an obvious relation to the inner; and all the mechanism of the inner ear to the auditory nerve; and the auditory nerve is con- nected with the brain. Sounds, as before intimated, are propagated by undulations from the sonorous body. These undulations striking the surface of the outer ear, are interrupted and softened by its various protuberances and cavities, till they enter the auditory passage. Here again, striking the surface of the | tympanum, commonly called the drum of the ear, they cause it to vibrate: this vibration moves the malleus; the malleus, the incus; the incus, the stapes; and the stapes affects the auditory nerve; and the auditory nerve conveys the tremulous motion to the sensorium. Here is as evident a contrivance for conveying sounds to the brain, as there is in the eye for conveying the images of surrounding objects by their being thrown upon the retina; and both are equally adapted to their auxiliary medium ; the eye to receive its image by-means of light, and the ear to propagate sounds along its concatenation of bones by means of air. But there are mysteries attending the operations of both, which probably will never be explained. We can no more demonstrate how this mechanism which we discover in the ear conveys an almost infinite variety of sounds, with perfect distinctness, to the 184 ORGANIZED NATURE. THE EAR ADJUSTS ITSELF TO DIFFERENT SOUNDS. sensory, than we can show how the retina of the eye becomes SENSIBLE of the image of objects thrown upon it, and how that image is conveyed to the brain along the opaque optic nerves. Notwithstanding these difficulties, the facts are unquestionable; and in the structure of the ear as well as the eye we find an astonishing display of power, under the direction of Infinite Wisdom, in adapting the contrivance to desired results, ad As in the eye we find suitable apparatus by which it can accommodate itself to the various degrees of light in which objects are seen, and the different dis- tances at which they are placed, so in the ear we meet with suitable machinery to anticipate varieties which would certainly occur from strong and weak sounds. ‘This is done by means of certain muscles which operate on the drum of the ear, so as to produce different degrees of tension in its fibres. I shall mention two only; by the one the membrane is tightened, and by the other it is relaxed. The first is the Tensor Tympani, so called, because it stretches tight the membranum tympani: it arises from the cartilaginous extremity of the eustachian tube, and is lodged in a particular groove within the tube; and, running over a sort of pulley, is inserted, by its tendon, into the handle of the malleus, which it serves to pull inwards, and consequently, by doing so, stretches the membrane to enable it the better to receive weak sounds. The other muscle arises from the auditory passage, passes through a notch in the ring of the tympanum, ORGANIZED NATURE, | 185 eee SSE ee SR THE EAR WONDERFULLY SECURED, —aaeeeeEeEeEEE "= and is inserted by the shorter process into the malleus. This is supposed to moderate violent sounds, by drawing the malleus from the incus, and thus inter- rupting the propagation of the sonorous tremors. By these means the finest sounds are heard with perfect distinctness, and the loudest without incon- venience; while these muscles adjust the tympanum with instantaneous celerity and perfect accuracy, to all the intermediate varieties. Ample provision is made for the preservation of this wonderful and important organ against all probable dangers. It has been proved that when the outer ear has been cut off, the sense of hearing has been greatly injured. Now had this been formed of bone it would have been in great danger of being broken; but being made of a gristly and cartilaginous substance, all the necessary uses of it are secured, and dangers avoided.—Insects are fond of hiding themselves in holes and crannies; but the fine membrane of the tympanum would be greatly endan- gered by their incursions, and ourselves seriously inconvenienced ; for were the drum of the ear touched by only one of their feelers, it would produce a sound more tremendous than the loudest peal of thunder. Hence their entrance into. the auditory passage 1s opposed by hairs growing outwards round the whole of its circumference, and the whole length of the tube. Besides this, a most bitter and un- pleasant mucus, of a yellowish colour, is secreted in the ear on which no known insect will feed. . For 1s6 ORGANIZED NATURE. USES OF THE WAX OF THE EAR. the production of this substance, round cells of a yellowish colour are placed under the skin, which discharge their contents by short ducts into the auditory passage. At first it is of an oily con- sistence, and serves as a liniment to defend the sensible skin of the membrane from the injurious action of the air and cold; and subsequently, by a change produced upon it, probably, by its eXx- posure to the atmosphere, it becomes the mucus mentioned, and answers a second important pur- pose. Who would have expected a chemical labo- ratory in such a situation, stored with a substance essentially different from all others hitherto discovered in the animal system, and gradually discharging it as necessity requires ° Whether, therefore, we con- sider the mechanism of this organ, its suitableness to the element of air to which it has a relation, or the means. of its preservation, we must be struck with the most evident design, and the most astonish- ing adaptation to a purpose of essential importance to the welfare of ‘man as the creature of God, and a member of civilized society. Supposing that man had been formed without the organ of hearing; and, labouring under innumerable ‘nconveniencies from this defect, he had felt the want of a faculty which should meet his necessities ; would he ever have thought of suc an organ? Suppose that he had started the general principle so far as it was necessary to receive sounds ; would he ever have conceived that the same mechanism ORGANIZED NATURE. 187 ——Eee——————————— EE MAN COULD NOT HAVE CONTRIVED AN EAR. could be employed to transmit with accuracy every variety of sound? It appears to me that it would have been infinitely beyond the reach of the strongest ~ and most inventive intellect that any creature ever possessed. But supposing that by some uncommon concatenation of circumstances, man had been led to this combination of principles in the same organ, and supposing that matter had been at his com- mand to model it as he pleased, and that he could have added to, or taken from his original system as he thought proper; what length of time would. it have taken him to form the drum, the bones, the muscles, the tendons, the nerves, the arteries, the veins, the glands and their ducts? How many thousands of experiments must he have tried before he brought them all to their due proportion? But, supposing all this, how could he give this won- derful organ a connexion with, and a relation to the general system, as it necessarily must have? He must first form the bones, and connect them with other bones of the head, and these very bones he must new model, in order that a suitable junc- tion may be accomplished. When he had done this, he must form a system of muscles of a dif- ferent shape from all others in the human system, and apply them to a different purpose from all others. ‘This were not all. After having made the arteries and the veins, he must seek out others lying in another part of the body with which to con- nect them: and having formed the nerves, he must 188 — ORGANIZED NATURE.

Without following this argument further; he must have new-modelled his own system in order to adapt to it this one additional piece of mechanism; and, in fact, be his own creator. As man is of necessity the work- manship of another Being, so, it is evident, that other Being possesses an omnipotent control over ~ matter; and that Infinite Wisdom has regulated all the operations of his power, in so combining the particles of the matter employed in the animal system in general, and this part of the human system in particular, as to answer purposes of essential importance, with the utmost certainty and mechanical ease, GHPP LOLS THE MOUTH. An examination of the mouths of animals of every description will afford the naturalist and the philosopher a’ great fund of amusement, a surprising exhibitiqn of mechanical contrivance, and a satisfactory demonstration of a wise adaptation. My observations shall now be confined principally to the human mouth.—The more purposes a piece of mechanism will answer, without any addition or subtraction of parts, or adjustment of its compo- nent levers, wheels, &c., the ‘greater is the skill and ingenuity which it displays. Could an engine be constructed which by the same mechanism ORGANIZED NATURE. 189 THE MOUTH FORMS ARTICULATE SOUNDS,.- —— would grind corn, and articulate words in unison with the most musical sounds, .and separate food of one particular flavour from a variety of other kinds of nourishment, it would very far exceed any thing which human skill has hitherto devised, and afford unquestionable evidence of great intel- ligence, foresight, and wisdom. But the human mouth does all this, and more. J is the means of speech, the instrument whereby food is masti- cated, and the organ of taste. | Tur Mouru is THE MEANS OF ARTICULATE sPEECH. With the use of the rRAcHra, or wind- pipe, a simple aperture would be sufficient for the production of sound ;. but, constructed as the trachia is, that sound would be inarticulate, however varied. In order that sound may be modulated and formed into any thing like words, a superaddition of me- chanism must take place, which will produce from the same original sound, as it flows from the orifice of the trachia, all the different notes, from the deep bass to the shrill treble. This mechanism is comprehended in the mouth, all the parts of which are subservient to the formation of words. In this the tongue is one principal instrument. It is so singularly constructed, and so remarkably supplied with muscles, that it can form itself into almost any shape with instantaneous promptitude, and direct itself to every part of the cavity of the mouth with equal ease. And so important is this member to the production of articulate sounds, thag, 190 ORGANIZED NATURE. Wie ti nap te eer ese a ee rerenrered THE MOUTH PREPARES FOOD FOR DIGESTION. Seen rr ee a none can be formed without it, as the loss of it demonstrates. The teeth, though not essential to articulation, are greatly subservient to it. ‘The lips also lend their aid, and without them various words ‘eannot be pronounced. They are supplied with muscles of remarkable activity and command, which, while they answer many other purposes, greatly aid the sweetness and variety of language ;—a gift which exclusively belongs to the human race. ‘Thus, by the aid of these Frew parts, formed, indeed, com- plexly and astonishingly, a small quantity of air, expelled from the lungs through the trachia into the mouth, is adequate to the production of every variety of sounds and words. Man is a thinking and rational creature: he naturally desires to convey his ideas to others of his species for their information or amusement; and the organs of speech subserve his wishes. ‘These organs not only have a relation to the air which is the medium of sounds, and to the ear which is adapted to convey them to the brain, but also to the understandings, the judgments, the wills, and the passions of those with whom we converse. And can we possibly conceive an apparatus better adapted to answer these inva- luable purposes? No. If Infinite Wisdom had not devised the means, man would have been for ever destitute of the invaluable blessing of speech. It is obvious that the human system is liable to decay, and stands in need of perpetual supplies of nutriment: but before this nutriment is fit for diges- ORGANIZED NATURE. 191 ee - - — THE TEETH. tion in the stomach, it must undergo a previous sepa- ration of its parts, and pass through a preparatory process : this is done in the mouth, which is remark- ably adapted to the MASTICATION OF FooD. All the parts which have’ been mentioned as co-operating in the formation of language, we shall now see lend- ing their respective aid to prepare food for recruiting the system,—an employment as different from the former as we can well conceive for the same instru- ments. For what similarity is there between the modulating of sounds into words, and the chewing of food? And yet it is impossible to say that the mouth performs the one of these offices better than the other, or that it is more exactly sdspied to the one than to the other. While the lips answer important purposes in the mastication of food, the reETH are the principal in- struments by which it is performed. In different per- sons they vary in number from twenty-eight to thirty- two. The body of each tooth is a bony substance of a much firmer texture than any other bone in the human frame. ‘They take their origin in the strong bones of the jaws; and, rising through the fleshy substance of the gums, appear above them covered with an enamel of a singularly solid nature, and of a composition pe- culiar to itself. As the horizontal surface of the teeth is the most worn and exposed to danger, it is worthy of remark, that the enamel is much the thickest on that part. And as it is perpetually wearing, a matter is constantly oozing through this solid body which 192 ORGANIZED NATURE. i anetipaarmmnicnsia sles spp a a a ce lO ae at EPO OOOO SS THE TEETH—JAWS. 4 petrifies as soon as exposed to the air, and this pre- serves the teeth in constant use for many years to- gether. Each tooth is supplied with an artery, a vein, and a nerve, which enter it through a small orifice in its fangs. : The teeth are divided into three descriptions. In the forepart of each jaw are four cutting teeth (incisores ) shaped like a chisel, broader at their en- trance into the gums, but gradually growing thinner till they are reduced to a sharp edge, exactly fitted for cutting and dividing our food. No other shape is so suitable at once for strength and usefulness. Beyond these are found two others in each jaw of a conical shape, resembling the tusks of carnivorous animals (hence called canini), standing rather above the other, and fitted for laying hold on the substance which is put into the mouth. Beyond these again are the grinders (molares), eight or ten in each jaw. They stand on a larger basis in their sockets, and are well calculated to resist the greater pressure which their broad summits are adapted to receive. ‘T heir large, irregular, horizontal surfaces are wonderfully suited to the grinding and the separating of solid food. As the two jaws have a relation to each other in their shape, and the disposition of the teeth, so the shape and disposition of the teeth in the lower and moveable jaw have a relation to the centre on which it moves. ‘This jaw may be considered as a kind of lever, with its fixed points at its articulations with the temporal bones. It derives its power from its muscles ORGANIZED NATURE. 198 | THE TONGUE ASSISTS IN. THE MASTICATION OF FOOD, enna ee which are most advantageously situated, being inserted into this lever nearly at the anterior extremity, . that is, nearly at the farthest possible point from the ful- crum, by which means they secure the greatest power over the food that is the object of resistance.—The power of contraction which these muscles possess is astonishing, being sufficient to raise a weight of several hundred pounds. I said that the shape and disposition of the teeth have a relation to the centre on which the lever in which they are placed turns. The front teeth have the disadvantage of being the farthest from the center of the lever; but this disad- vantage is compensated by their hiner sharpness. The molares, on the other hand, have not the sharp- ness of the incisores ; but this disadvantage is com- pensated by their being placed nearer the fulcrum. Thus we see that principles strictly mechanical are wisely combined with usefulness ; every difficulty is anticipated and overcome.—Let it be also remarked, that the lower and moveable jaw has not only a per- pendicular motion for cutting and pressing the food, _ but also a considerable rotatory horizontal motion, for grinding and separating its particles, acting on the same principles with the two stones of a corn-mill, | the lower of which is fixed, while the upper moves round horizontally. The tongue on the inside of the teeth, and the cheeks on the outside, also render essential service in the mastication of food. By the variety and strength of its muscles, the tongue is enabled to accommodate ) 194 ORGANIZED NATURE. —— THE USE OF SALIVA. itself to the food in the mouth, to turn it over, to alter its position, and to insert it between the teeth till it is reduced to a proper state for the reception of the stomach. While the tongue is thus employed in the inside of the teeth, the muscular substances of the cheeks perform an important office on the outside. For every time the mouth opens in the chewing of food, the cheek is stretched over the cavity made be- tween the upper and lower jaw, and consequently forces back again the food which had been pressed over on that side. The lungs also assist their action on pneumatic principles. . When it is necessary that the food should be forced inward further than the exter- nal line of the teeth, the lips are closed, the lungs draw the air from the cavity of the mouth, a vacuum is instantly formed, and the external air, pressing on the outward surface of the cheeks, forces them through between the teeth of the two jaws; and, if necessary, beyond them. ‘The great elasticity of the cheeks is exactly suited to these purposes. But something more than a reduction of the food to a sufficient fineness is necessary in order to prepare it for the stomach. It must not only be reduced small that the stomach may act upon it with greater effect, but it must be brought into a pulpy state by a proper mixture with some fluid, when the food is too dry. This is done by the sativa, which is an insipid liquor flowing plentifully from the hps, cheeks, tongue and palate, from various reservoirs situated in the neighbourhood, and pressed into the mouth by the ORGANIZED NATURE. . 195 . THE MOUTH IS THE ORGAN OF TASTE. ; different muscles which are called into action by chewing the food.—The principal of these reservoirs is the PAROTID GLAND, which fills up a large interval between the auditory passage and the lower jaw. It sends its large duct, which is about the dimensions of a straw, into the cheek, where it pours its contents into the mouth through innumerable apertures. During trituration this fluid is mixed with the food, together with a considerable quantity of atmospheric air, which is also necessary in the process of digestion. Thus, when the food is properly prepared, it is placed upon the tongue and transmitted through the esopha- gus, or gullet, into the stomach. | While eating the food which our bountiful and compassionate Benefactor provides, how little do we think of its component parts,—of the surprising me- chanism which he has formed in order to prepare it for nourishment,—or of the amazing variety of organs which are called into action, and that astonishing process which is going on every morsel we chew! An attentive consideration of these subjects is highly calculated to produce conscious dependance on Him in whom we live, and move, and have our being, and to excite the highest strains of gratitude to the only wise God. | The mouth performs another important office. It is the orcan oF TAstTE. The instinct of man in the choice of his food appears to be far below that of many brute animals. In general, they are able to make an infallible choice before they receive it into 0 2 196 ORGANIZED NATURE.

But his reason compensates for the inferiority of his instincts, and his taste in general will decide in cases where his eye or his smell may be wanting in accuracy. Before I proceed to consider the organ of taste, 1 shall just notice that of smELLING. ‘This is con- fined to the nose, which is supplied with nerves that are almost naked and of singular sensibility, so that even the delicate effluvia which is: perpetually arising from almost all substances, affects them. The formation of the human head into that of an oval figure, has given to the organ of smelling but a small extent of surface ; but to enlarge this the more, the Creator has made the internal parts of the nose variously hollow and complicated. in a surprising manner’. By the smell we can often determine the qualities of bodies, and their fitness or unfitness for food. For nearly all those substances which God has appointed for nourishment are endowed with grateful smells. The situation of this organ is also deserving of notice. The nose is placed with its open cavities immediately over the mouth, it should seem for this reason, that the nature of substances may be detected by their effluvia, before they are taken into the.mouth*’. However the smell of some substances is pleasing, but their natures * Haller. * “As salt joined with an oil, is the object of taste; so a volatile oil, aided with salts, serves to excite smells: whence the affinity of the two senses, which conjointly assist and move each other, may be easily understood.” —Jd. ORGANIZED NATURE. 197 STRUCTURE OF THE PAPILLA. destructive. Therefore had we this sense only, we should commit mistakes destructive of life. God has therefore wisely granted the organ of Taste in the very place where food is prepared for the stomach, which corrects the mistakes that may be made by the smell, and judges of the suitableness of what is re- ceived by its essential qualities. Though the mouth, in general, is able to taste the qualities of bodies, yet the tongue is the prin- cipal organ of taste. The paprLu#, or nipples, by means of which it performs this important office, are placed on the upper surface of the tongue. These are divided into three descriptions. The largest are situated near the basis of the tongue, and are shaped like an inverted cone; the next are slenderer than the former, of a cylindrical form, and lie more forward; the third sort are of a conical figure, and are placed amongst the other. The construction of these papillae is remarkable; each having its pulpy fabric composed of slender nerves, arteries, and veins, united or wound up with a firm cellular substance into a protuberance, of which many are required to make up one large papilla.’ These are as so many TAsTERs; which, during the process of mastication, examine the qualities of the food, and approve or disapprove according to. its nutricious or its noxious qualities, almost with infallible certainty. It is owing to MAREE O56 5 sh) Ad EUR AA Bo ARLE ‘Th. 198 ORGANIZED NATURE, THE SENSE OF TOUCH. these, that food is so gratifying to the palate; and this pleasure is an ample recompence for the ne- cessary labour of mastication. ‘Thus we see that scarcely a grain of any substance can be allowed to enter into the stomach without having its qualities examined with the strictest impartiality. Whether we consider the structure of this organ, or its situation, or its uses and importance, we must be struck with the most evident design, the most amazing goodness, and the most inscrutable wisdom in the Author of our being. The mouths of all animals are adapted to their necessities. To meet their various exigencies, their general structure is amazingly varied, as we have seen in numerous instances. The same skill is evident, and displayed on a nobler scale in that of man. The short sketch which I have given of its general structure is enough to excite our curiosity and our wonder. POL AL OS THE SENSE OF TOUCH. Toucan is another of the senses we enjoy, and another of the means by which we obtain ideas. I shall only just glance at it, and dismiss this part of our subject. By the roucu we obtain a know- ledge of the external properties of bodies, as to their roughness or smoothness, their temperature, their moisture or dryness. The nerves being dis- ORGANIZED NATURE. 199 A REVIEW OF THE SENSES. tributed over the whole surface of the body, every part of it possesses this sense in a less or greater degree. But the ends of the jingers are particularly formed for this office; being furnished with papille similar to those of the tongue, in considerable quan- tity. The importance of this sense is obvious ;—by it we perceive heat, when it exceeds in bodies the heat of our fingers, and weight likewise when it presses more than usual. Humidity, we judge of by the presence of water; softness, by a yielding of the object; hardness, from a yielding of the finger; figure, from the limits, or rough circum- scribed surface; distance, from a rude calculation made by experience, to which the length of the "arm serves as a measure. So the touch serves to correct the mistakes of the other senses; but yet it sometimes errs itself, and then the other senses show themselves to be true guides to the animal without that of touch." Notice has been taken of the five senses. Where an organization has been evident, its structure has been described. They are so many different means of ‘obtaining ideas of external objects. As it is by the nervous system alone that ideas are con- veyed to the mind, all the difference that exists between one of the senses and another, is in the external apparatus by which the idea is FIRST re- " Tb. 200 ORGANIZED NATURE. w=. oO oes SSSR ee ceived, and communicated to the extremity of the nerve. Some objects are tangible and near; the senses of touch, taste, and smell, are adapted to them therefore as such; and we have but to bring them into contact with the ends of the nerves as exposed on the surface of the skin, to convey to the brain the ideas of taste, smell, and touch, with all their infinite varieties. This deserves particular notice, as being highly calculated to excite our surprise ; - that, though the almost: infinite variety of objects with which our globe abounds, have’ all their. pe- culiar and differing qualities in some respect. or other, yet all these differences, with their minute shades of variety, are conveyed to the mind by the nerve, without. its undergoing any change by adjustment, or alteration in its condition. Other objects are remote; we cannot form any ideas of them by these senses, and yet it is of vast moment to us that we should be acquainted with them. The senses of serine and HEARING are intended to convey ideas of them to the mind. The idea of some of these objects is conveyed through the medium of light, that of others, through the air: we find, therefore, two pieces of mechanism of a most singular structure connected with the ends of the nerves, the one exactly adapted to the recep- tion of the images of objects by the aid of light, and the other as well adapted to the reception of sounds created by other objects and propagated through the air, ORGANIZED NATURE. 201 INTERIOR STRUCTURE OF THE HUMAN FRAME. Though all these senses may be destroyed, and yet the life of man perpetuated—notwithstanding, if but one of them is lost, he loses with it a great part of his animal enjoyment, or his relative im- portance. By these means we obtain all our ideas of external objects, and act accordingly. Viewed separately, each is a proof of a wise adaptation of means to given purposes; but viewed as united, and united in the same system of animal mechanism, subserving different purposes essential to the well- being of the whole, we must be struck with amazement, and confess that it is the workmanship of Infinite Skill. | OLLI PL OL THE INTERIOR STRUCTURE OF THE HUMAN FRAME. Having considered the wisdom of God in adapt- ing the members of the human body to the functions which they are to discharge, and viewed the same attribute as displayed in the means of obtaining ideas by which man is to regulate his actions; let us now enter into the interior of this singular fabric, and examine the mechanism by which the whole is put in motion. To give the system support and firmness, it is. supplied with bones ;—I shall consider their structure and articulation :—To afford the bones motion and apparent symmetry, they are clothed with muscles and tendons ;—I shall notice their form and use :—And to communicate to the muscles their 202 ORGANIZED NATURE. oe re areata a Sere En EN I HUMAN BONES. power of action, they are furnished with nerves ;— I shall describe their nature and importance. These subjects will explain the physiology of the animal economy in general, and that of the human frame in particular. A short description of each will be all that can be expected in this work, which proposes to consider these subjects so far only as they afford a manifest demonstration of Divine Wisdom. THE BONES. To give the animal system support and firmness, it is supplied with bones ;—TI shall consider their struc- ture and articulation.—The bones form the pillars, the beams, and the rafters of the earthly house of our curious tabernacle, and merit our attention. In their general structure and connexion with each other, the same divine skill, foresight, and power, appear, as are demonstrated in all other parts of the animal economy. . In considering the stracture of bones, we must notice the materials of which they are composed. For what at the first sight appears but a simple, - uncompounded body, as was remarked before, is found, by chemical analysis, to be composed of a variety of strange and heterogeneous substances. “Bones consist chiefly of jelly, fat, and an earthy neutral salt. By distillation they yield hydrogen and carbonic acid gas, a volatile alkaline liquid, an ORGANIZED NATURE. 203 OSSEOUS MATTER IN MILK. empyreumatic oil, and dry carbonate of ammonia*.” These materials are so arranged and combined as to form a substance remarkably hard and difficult of separation, and singularly strong and light.—The human skeleton of an adult weighs about nineteen or twenty pounds only. When animal bones are divested of their oil and jelly, the earth which remains is chiefly lime, united with phosphoric acid. It is worthy of notice, that phosphate of lime is found in abundance also in milk. This seems to indicate, as Mourcroy beautifully remarks, “ that Nature thought fit to place in the first nourishment of animals a quantity of osseous matter, with a view to the necessary celerity of the formation and growth of the bones in the earliest stage of their lives.” This fact is probably unknown to some who study natural history, and is one of the numerous instances of the beneficence of the Creator, exemplihed by the science of chemistry. ‘The more we know of the minutiz of matter, and of the laws by which it is governed, the greater occasion shall we have to admire the excellence of contrivance and the bene- volence of the intention of the omnipotent Artificer. Let the advocates for chance consider the aforesaid fact; and say, if they can, that phosphate of lime is found in animal milk, in consequence of fatality, and that it occurs by accident where it performs so important an office in the animal economy.——It is * Parkinson’s Memoranda Chemica.—See also Fourcroy'’s Chemical Philosophy, 3d Edit. p. 275. 204 ORGANIZED NATURE. ie Ss Soci huce Py SQN also a remarkable fact, that the nearer the female approaches to the period of parturition, the more is the milk charged with this calcareous phosphate; and that it is not till the digestive organs of the infant are sufficiently strengthened to answer the purposes and the work of animalization, that this earthy salt disappears from the milk of the mother.’ In all the works of God, the smallest possible quantity of matter is employed consistent with the strength which is required: and in all these works we find that the materials are disposed and arranged with relation to each other, so as to afford the greatest strength of which they are capable. Every particle is in its proper place. These remarks particularly apply to the bones of animals. Some of them we find more solid, others more porous. This is often observable in different parts of the same bone. The extremities are large, but then they are spongy; the centre is small, but then it is solid and compact ; so that what it wants in size, it gains in solidity. In this shape of the bones there is evident design. Being smaller towards the centre, more room is left for the muscles: and being enlarged considerably towards their extremities, a greater surface is obtained for their bearings upon each other. In examining the animal skeleton, we find that this almost univer- sally obtains; it is evident in the shortest bone in the human finger. A a ER IRE SCAR ~ ¥ See Parkes. ORGANIZED NATURE. 205 CAVITIES OF BONES—THEIR PROCESSES, The pores and cavities which we discover in the bones are constructed on mechanical principles; so that by their shape they compensate for the deficiency of solidity: that is, they are not angular, but oval or circular, by which shape they gain all the advan- tages of the arch. Where any bone is perforated to admit an artery, or nerve, or tendon, this is the shape of the cavity. By this means, much matter is saved, and yet the strength is secured. We find this to be the fact, with regard not only to the long bones, but also those which are flat and thin. In these, two plates lie parallel with each other at a short distance; they are separated and connected by a celular sub- stance, where only a very small quantity of matter is employed; but being thrown into circles and arches, and united to the plates, they give them at once great strength and astonishing lightness. By this means also room is allowed for the marrow which is every where essentially necessary in order to keep the bones from dryness and consequent brittleness. In viewing the external shapes of bones, we see — constant irregularity. Few, if any, are perfectly straight. But they are bent in that direction which gives them a strength superior to what they would have were they straight. Their numerous processes, or protuberances, act as so many buttresses, adding considerable strength to the parts to which they are attached.

It is obvious that, as the bones act one upon another, and that their pressure against each other is very considerable, they are liable to wear by the conse- quent friction. This evil is anticipated, and suitable provision is made against it. The ends of the bones are covered with a cartilaginous substance of a singularly close and firm texture, extending over the head of the bone just so far only as it is necessary, that is, as far as the bone plays upon that with which it is articulated. And besides this, the joints are supplied with an oily mucus, which is constantly spread all over those parts which are exposed to friction, by which means they act upon one another for many years without feeling the least incon- venience, or discovering the sinallest wear. From the extremity of this smooth cartilaginous substance, a fine membrane (the periosteum) commences, spread- ing itself over all the rest of the bone. ‘The exigency of the case evidently required that all the bones in the skeleton should be joined toge- ther in such a manner as to allow of considerable motion upon each other, and yet to maintain great firmness and union. ‘The manner in which the bones ORGANIZED NATURE. 207 Po a eo Ra Fe ET JOINTS OF THE SHOULDER AND ARM. a eeeenereee are terminated, exactly accommodates them to each other; and in every instance through the whole system, they are so formed as to allow of the necessary motion, and in the direction which is required. While in some articulations all that is wanted is that they allow of a motion in one plane only, horizontal or otherwise, it is equally evident that in others they should be such as to admit of a motion in all direc- tions—as, for instance, in the arm. Hence arises the necessity of different kinds of articulations :—these really obtain. A consideration of the structure of the arm will sufficiently illustrate this part of our subject. Its different bones are so united as to admit of all movements necessary in one of the most useful members of the human system. ‘The articulation at the shoulder is by means of a round socket in the blade bone, which receives the hemispherical end of the bone of the arm which it exactly fits. By this kind of union it is evident that the arm may be directed to any given point of a circle. This is the only articulation in the arm where this motion could be secured with equal advantage. The joint at the elbow is very different. It is something like a hinge, the prominences of the one bone nicely fitting into the cavities of the other, both of which lie ina direc-_ tion across the diameter. of the bone, consequently the fore-arm is only allowed to move in one plane as it regards the bone with which it is united. But by means of the articulation at the shoulder, this plane 208 ORGANIZED NATURE. SSS SSS ULNA AND RADIUS. , ey a a may be at every point of obliquity, from the horizontal to that which is perpendicular. In order to accommodate itself to the various positions which are necessary, it is evident that the hand should have vast liberty of action. Singular provision is made in the bones of the fore-arm with which it is joined, that these purposes may be accomplished. The fore-arm (I mean. that part of the arm which extends from the elbow to the wrist) is composed of two bones, called the unna and - xADIUS, which lie parallel to each other, The ulna is considerably larger at its upper extremity than it is at the lower, in order that it may be united with the large bone which extends to the shoulder (os humeri). The radius, on the contrary, is larger at the lower extremity than it is at the upper, in order to its junction with the bones of the hand. Its upper end is cylindrical, and received into a corresponding cavity in the ulna, in which it rolls when the palm of the hand is turned up or down. As the hand is connected with the ex- tremities of these bones by a hinge-like articulation, it is obvious that this essential rotatory motion could .not have been obtained in. any other way which we can conceive, with so many advantages and so few inconveniences. A principal somewhat — similar is. observable in the articulations of the lower extremities, though the bones are very dif- ferent in shape and size. ; ORGANIZED NATURE. 209 HOW THE HEAD IS JOINED TO THE SPINE. ; ae eee I shall mention one instance more in which there is a remarkable adaptation ;—it is in the manner in which the head is united with the spine, in order to allow of those motions which are neces- sary. Two kinds of motion are wanted; the one is rotatory, from side to side; the other is back- wards and forwards. Both these are obtained in the following curious manner. The back part of the head is articulated. with the first vertebra of the neck by the hinge-like joint, by which it is enabled to move backwards and forwards. At the upper part of the second vertebra there is a tooth- like projection which serves as an axis, or pivot: on this pivot is placed the lower surface of the first vertebra, which has received a suitable shape for moving upon it. What could not be secured by one articulation is accomplished by two; and yet in such a manner as to allow of the passage of the spinal marrow from the brain through them to the inferior vertebrae. When the rotatory motion of the head is performed, it turns upon this pivot: when it moves backward and forward, the hinge-like articulation is called into action. One grand object of these different motions is, that we may have a more complete and ready command of surrounding objects : and the cornea of the eye being at a short distance from the centre of the rotatory motion, it describes a small circle. By this means we are enabled to see almost all around -us by the motion of the head. only, without altering the position of P 210 ORGANIZED NATURE. THE MECHANISM OF THE BACK-BONE. the body. Not to perceive in all this the most astonishing marks of infinite skill, would argue a ‘degree of blindness, which we should think im- possible to exist in a rational creature. These two singular bones are the first of a series of bones extending from the lead to the lower extremity of the back. They form the spine, or back-bone, which is a chain of joints of very won- derful construction. Various, difficult, and almost inconsistent offices were to be executed by the same instrument. It was to be firm, yet flexible; (now, I know no chain made by art, which is both these; for by firmness I mean, not only strength, but stability ;) firm, to support the erect position of the body; flexible, to allow of the bending of the trunk in all degrees of curvature. It was further also (which is another, and quite a distinct purpose from the rest) to become a pipe or conduit for the safe conveyance from the brain of the most im- portant fluid of the animal frame—that, namely, upon which all voluntary motion depends—the spinal marrow ; a substance not only of the first necessity to. action, if not to life, but of a nature so delicate and tender, so susceptible, and so impatient of injury, as that any unusual pressure upon it, or any considerable obstruction of its course, is fol- lowed by paralysis or death. Now, the spine was not only to furnish the main trunk for the passage of the medullary substance from the brain, but to give out, in the course of its progress, small ORGANIZED NATURE. S11 lll EEE HOW THE BONES ARE HELD TOGETHER. pipes therefrom, which, being afterwards indefinitely subdivided, might, under the name of nerves, dis- tribute this exquisite supply to every part of the body. ‘The same spine was also to serve another use, not less wanted than the preceding; viz. to afford a fulcrum, stay, or basis, (or, more properly speaking, a series of these,) for the insertion of the muscles which are spread over the trunk of the body; in which trunk there are not, as in the limbs, cylindrical bones to which they can be fastened: and likewise, which is a similar use, to furnish a support for the ends of the ribs to rest upon.’ An examination of the back-bone of a hare or any other quadruped, which strongly resembles that of man, will prove that it is singplarly adapted to these various purposes, and that a better con- trivance for its intended uses cannot be imagined. The bones are held together by L1GAMENTS,— white, shining, and inelastic ; of a compact substance, remarkably strong. They have different forms ac- cording to their different situations:—some round, others flat and broad; and firmly attached to the bones which they bind together. In the hinge- like joints they are attached to the sides in order to allow of motion in only one direction: in those articulations which admit of motion every way, as for instance, the arm at the shoulder, they are capsular, surrounding the whole joint like a purse. a * See Dr. Paley’s Natural Theology. R2 212 ORGANIZED NATURE. RECAPITULATION,. It belongs to the anatomist to be more particular on this subject. It 1s but for me to observe, that the whole animal system is provided with bones most suitably formed and firmly articulated, fit for action. Through the whole animal skeleton we see the most evident design, and the most inscrutable _ wisdom. Here are bones of various shapes, lengths, 3 and sizes :—articulations the most suitable :—all is constructed on principles perfectly mechanical ;-— nothing is redundant, nothing deficient :—strength is no where given where it is not required; it is no where withheld where it is wanted ;—though the whole appears deformed, yet the whole is perfect order. ‘The skull is adapted for the reception of the brain :—the vertebre to support the head, and allow of the necessary inflections of the body :— the ribs are so bent and arched as to form a cavity for the security of the vital functions :—the arms and hands suited to an almost infinite variety of positions and important offices:—the legs and feet are evidently formed to support, and give locomotion to the system. The whole is most evidently the workmanship of an Almighty agency, and an infinite intelligence. This mechanism is most obviously intended for use, for action, for motion; yet, how- ever curious the machinery, it has no power of moving itsel{—something more is wanted :—To afford the system motion and apparent symmetry, it 1s sup- plied with MuscLEs and tTENDONS:—ZI shall now consider their form and use. ORGANIZED NATURE. 213 STRUCTURE OF MUSCLES, MUSCLES AND TENDONS. As all animal motion is effected by the muscles, and as their action is essential to the well-being of the animal economy, every inquisitive mind will be desirous to understand their general structure and application.— A brief examination of them will afford a still further discovery of Divine Wisdom. The muscles are those fleshy substances which we find in almost every part of the body, filling up the inequalities of the bones, and adding symmetry and beauty to the whole. They are of various forms and sizes, according to their respective uses in the animal system,—but all possessing one grand essential principle; that is, a power of contraction and relaxation. Each is composed of an infinite number of fibres, lying, in some, in the same direc- tion parallel with each other; and in others running in all directions, but all contributing to the general strength of the whole. Could we ascertain the construction of one of these fibres, we should have but to suppose a vast multitude of them joined together, and covered with a membrane, to form an accurate idea of what is called a muscle. But though, by chemical analysis, their various pro- perties may be ascertained, yet how these properties are arranged and united in the formation of the 214 ORGANIZED NATURE. MUSCLES——-TENDONS. muscular, fibre, has hitherto eluded the strictest research. However mysterious the structure of the muscle may be, the fact is beyond a question, that it possesses a power of contracting considerably in length, by the application of stimulus,—and_ that when this stimulus ceases to act, it relaxes again to its former state. It is also certain that all mus- cular contraction takes place from the extremities. towards its centre. The muscles we discover in the animal system are of two kinds: the one znvoluntary, comprehending such as act independently of the will of the animal; on the action of which the life of the animal de- pends, and which continue to act whether it is asleep or awake:—the other are voluntary, em- bracing those which are called into action when wanted. ‘The heart, on the action of which circu- lation depends, is of the former, and those by which the animal moves from place to place, are of the latter kind. ) But, in a muscle, we not only find the fleshy fibre on which its irritability and consequent con- traction depends, but also ¢endinous fibres. These are of a firmer texture, of a white glistening colour, insensible, without irritability, or the power, of con- tracting. They are interwoven into the body of the muscle, but are collected together at its extre- mities, forming TENDONS of various shapes, sizes, and lengths, according to the purposes to which they are destined. ORGANIZED NATURE. 215 . MUSCLES CONVENIENTLY SITUATED. In the structure of the muscle, provision is made for contracting its length; and in that of the tendon, a contrivance by which it may operate upon any distant joint to which the tendon may be attached. The body of a muscle may be compared to a wind- lass, the tendon to a rope attached to it, which may be carried over a pulley, or in a straight line, and fastened to any distant object. When the windlass is turned round, it acts on the rope and draws the object nearer. Similar to this is the action of the muscle on the tendon, and conse- quently on the bone to which it may be attached.— Let us now consider them in their application in the animal economy. In their application, as well as In their structure, we see the same unerring skill. The muscles are firmly attached to the bones in those situations where they may be placed with the least inconvenience, and where they may act with the greatest freedom and effect, though the part on which they act is frequently at a considerable distance. As, for instance, the muscles which move the fingers are placed on the bones of the fore-arm. But though the cause of action is at so great a distance, yet by means of the tendons, which some-' times pass through each other to act on the different joints, motion is produced at the very ends of the fingers. Another instance of a similar kind is found in the tendons of the foot: the muscles which make them. act upon the foot and toes are placed upon the leg. Some of these tendons, as well as those 216 ORGANIZED NATURE. a i THE JOINTS ALLOW THE MUSCLES GREAT ADVANTAGES. of the arm, are nearly twelve inches in length. It is obvious that tendons running to such a distance must be exposed to injury from friction or pres- sure in the grooves formed in the bones for them. Now, singular provision is made to prevent these evils. Hence they are surrounded by a tendinous. sheath, in which a mueus is frequently found, that keeps them oiled; by this means they move with ease, and injuries are prevented.* The formation and articulation of the bones have an evident relation to muscular motion, so that in many instances the muscles have a peculiar advantage in acting upon them. ‘The manner in which the. bones of the foot are joined with those of the leg, will afford an illustration of this idea. This union is not at the extremity of the heel, but at a considerable dis- tance from it. The centre on which the foot turns being therefore at a distance from the heel, the muscle of the leg, the tendon of which is inserted at the ex- tremity of it, acts upon the foot with peculiar advan- tage. Indeed this is essentially necessary. For every step which we take in walking, the whole weight of the body is thrown upon the forepart of each foot alternately: therefore, though the muscle of the leg and its tendon be the most powertul in the human frame, yet without this mechanical advantage, they would have been insufficient to afford the neces- sary support. ‘This mechanical advantage allowed to * Encyclop. Brit. ORGANIZED NATURE. | 217 KNEE-PAN, the muscles over the bones, is particularly seen in the middle jomt of the hind legs of dogs, and all quadrupeds, where the end of the bone extends con- siderably beyond the joint, that the muscle may act with the more force. It is by the power afforded to this joimt principally, that these animals throw them- selves forward in the act of running. Their fore-iegs do little more than support the body in their rapid movements. | The knee-pan (patella) appears to be another’ mechanical contrivance something like a pulley, to give advantage to the action of the muscles. This is a moveable bone placed over the joint of the knee. The muscle which brings the leg forward is placed on the thigh bone; its tendon is attached to this bone :—another tendon is attached to its opposite side which is inserted into the bone of the leg a little below. By this means the action of the muscle is thrown at a distance from the centre of motion in the knee articulation, and consequently it acts with an advantage proportionate to this distance. On the under side of this same joint we meet with another mechanical: illustration of a nature somewhat. different. The muscles situated at the under part of the thigh send off two strong tendons which are inserted into the bones of the leg below the joint. Now were these tendons bound down close to the bone by the surrounding ligaments, it is evident that they either could not act at all, or with but very feeble effort in rajsing the leg backwards in walking, 218 ORGANIZED NATURE. ANTAGONIST MUSCLES, because they would act close to the centre of motion. But the ligaments being lax, and allowing the tendons to start off a considerable distance from the centre of motion, the muscles act under all the advantages of a lever. The same is observable in bringing the fore-arm forward, and raising it up. Were there xo preventives, however, the tendons passing over similar joints would start up to an inconvenient distance from the bones: and therefore they are all bound down by strong circular ligaments, whose fibres run at right angles with those of the tendons which they confine, and yet allow some space to give-the above- mentioned advantage to the muscles. These liga- ments are seen at all the joints of the fingers inwardly. What singular contrivances to accomplish designs and avoid disadvantages ! All the jomts are supplied with two sets of muscles and tendons which act on the opposite sides, the one to bring them forward, and the other to carry them back again, and hence they are called dntago- nists: when the one contracts, the other relaxes, as” for instance, in bending and straightening the finger. Were they both to act at the same time, no motion would result. Besides those muscles which pro- duce motion in the same place, there are others which lie across at different angles; to produce action in other directions in those parts of the system whose articulations allow of it :—for instance ;—besides the muscles which move the leg and thigh forward and backward, there is another called the tailor’s muscle, ORGANIZED NATURE. | 219 Ce eeeeeeeeeeeaoaoaoaoaoaoaoeoeeeeeeeeeeeeeeeeuwwuwyss A REMARKABLE MUSCLE IN THE EYE. which passes obliquely from the inward part of the thigh a little above the knee, to the groin outwardly, by means of which we are enabled to turn the knee and foot outward. A similar contrivance is seen in order to give the fore-arm a kind of rotatory motion, A muscle passes from the inside of the arm above the joint, and goes obliquely over it, and is inserted into the radius; this turns the fore-arm inwardly: another is placed on the opposite side, whose action turns it outwardly. By the action of these two alternately, this important member is put in po- sitions essentially necessary in a thousand actions of life. In some of the muscles and tendons we observe remarkable contrivance to bring them to act where their action is wanted. One of the muscles of the eye (the obliguus superior) is a striking instance. The design of it is to draw the globe of the eye for- ward, and to turn the pupil downward, As the muscle is placed: behind the eye, how is.this to be done?—why, from its origin it passes in a direct line towards a small cartilaginous ring which is placed over the eye forwards; the tendon passing through this ring, turns back again, and is then inserted into the upper part of the globe of the eye, Hence it is clear that when the muscle contracts in length, the tendon operating on the globe of the eye, must pro- duce the position intended. Can we conceive how these effects could be otherwise produced,—or pro- duced by a more mechanical contrivance? Bs CO” ORGANIZED NATURE. MUSCLE OF THE EAR—OF THE JAW. There is a-small muscle in the ear (the stapedeus) to which, though mentioned before, I shall again advert in this place, as discovering equal contrivance with the above. It is the smallest in the human system: it arises in a little hole in the hinder part of the cavity of the tympanum: its tendon passes through a hoop in the same cavity, and then is fastened to the head of the stapes. When the muscle contracts, it draws the stapes obliquely upwards, and assists in stretching the membrane of the tympanum to adjust it to different sounds. Another instance of singular mechanism of a similar kind with the above, is the muscle by which we open the lower jaw. ‘This muscle (the digastric) rises on the side of the face, considerably above the insertion of the lower jaw, and comes down, being converted in its progress into a round tendon. Now it is manifest that this tendon, whilst it pursues a direction descending towards the jaw, must, by its contraction, pull the jaw up instead of down. What then was to be done?—This, we find, is done. ‘The descending tendon, when it has got low enough, is passed through a loop, or ring, or pulley, in the os hyoides, and then made to ascend; and having thus changed its line of direction, it is inserted into the inner part of the chin: by which device,—viz. the turn at the loop, the action of the muscle (which in all muscles is contraction) that before would have pulled the jaw up, now as necessarily draws it down. ‘The mouth,” says Heister, “is opened by means ORGANIZED NATURE, |. 221 NERVOUS SYSTEM. ———— of this trochlea in a most wonderful and elegant manner.” How easily are difficulties met and overcome when Infinite Intelligence contrives, and Almighty Power executes!

This part of the animal economy, though of essential importance to all animal motion, affords less APPARENT adaptation of means than any other organs which the system contains. We know the fact, that the nerves propagate motion through the muscular system—but how, and in what manner, are enquiries which we cannot solve. To answer these questions, physiologists have used their utmost industry and acumen; but it still remains one of the mysteries of nature, and affords proof of the imbe- cility of man. The nerves take their origin in the » See Paley. a A A TD tg - THE HUMAN BRAIN. — brain,—we must therefore notice the fountain wetare we attempt to follow the streams. The brain is contained in the cranium, which is admirably formed at once to contain it, and afford it protection from injury. The bones of the scull are remarkably strong, and especially in those parts where danger is the most probable. In order that it may afford more security to the brain, the scull is lined by a membrane (the duramater) of a texture singularly strong, which sends off innumerable fibres — into the pores of the surrounding bones to which it firmly adheres. The brain fills the whole of this cavity, but is every where invested by another covering (the piamater) which is also of considerable strength. The brain itself is of a soft pulpy nature’. ‘To attempt to describe it would afford but little in- terest, and occupy more room than would be com- patible with the plan of this work. I must beg to refer the reader for further information to anatomical authors. Let it be enough to remark, that it sends off a long trunk through a circular opening at the under side of the cranium, down the vertebra of the back :—for, in fact, the spinal marrow is only a pro- longation of the brain: and in the one or the other, all the nerves take their origin. ¢ Till recently, its organization was almost unknown, and by some denied. Drs. Gall and Spurzheim have lately, however, professed to have demonstrated its organization to a consider- able extent,—with what success, remains to be determined. ORGANIZED NATURE. | 223 NATURE OF THE NERVES. By a nerve is meant, a white, glistening, and inelastic cord, whose essential properties are. the same as the brain or the spinal marrow im which it originates; it is the means of stimulating the muscles to action, and of conveying sensation to the sensorium from the different parts of the body, though not at all irritable themselves.—Of nerves, there are thirty-nine or forty pairs in the human body ; nine of which are sent off immediately from the brain to the eyes, the ears, the nose, the mouth, and various parts of the head; the remainder take their origin in the spinal marrow, and are sent off in all directions through the lower parts. of the system. At their origin they form large trunks ; but as they pass along, in general they divide, and subdivide, till they fill every part of the system with the most minute fibres so completely, that it 1s impossible for a gnat to insert the point of its sting without wounding some of them, and pro- ducing pain. The nervous system appears to be particularly subservient to the mind; being that by which we derive our ideas of what is external, and that by which the mind acts upon every part of the body which is subject to its volitions. It is by the nerves that we obtain our ideas of what is external. Deprive the animal of its nerves, or let them lose their power of acting, and it is instantly bereft of all its vital energy, and no longer retains a capacity of obtaining knowledge. 224 ORGANIZED NATURE. IMPORTANCE OF THE NERVES. The eye may preserve its former structure, and a suitableness of parts for the reception of the images of surrounding objects upon its retina; but destroy the nerve, and no such image will be conveyed to the sensorium,—this astonishing apparatus is instantly rendered useless. The structure of the ear may con- tinue as before; but it is in vain that the external ear receives the sounds as propagated through the air, and conveys them to the tympanum; and the tympanum communicates its vibrations to the chain of bones which is connected with it, if the auditory nerve be incapable of action. No sound will be heard.—No violence may be done to the organs of the mouth, the nose, nor the fingers;—but the senses of taste, smell, and touch, are no longer enjoyed, unless the nerves of the parts retain their power of communication. It is by means of the nerves that the mind acts upon all the parts of the body which are subject to its volitions. ‘There are some parts of the animal which the will cannot control. This is the case with all the vital functions, such as the heart, and the consequent circulation of the blood ;—the lungs and the action of the diaphragm, and various other parts. This important fact shows that our lives are not at our own disposal. ‘The muscles of these parts are called involuntary muscles.—There are other parts of the system which act in obedience to the will, such as the eyes, the hands, and_ the feet; and the muscles of those parts are called ORGANIZED NATURE. — ’ 225 HOW THE NERVES ACT ON THE MUSCLES MYSTERIOUS. voluntary muscles. Obtaining a knowledge of what is external by means of the senses, we immediately form a judgment of what line of conduct we must adopt to avoid danger, or to obtain that which appears beneficial;—this being determined, the will exerts an influence on the powers to be put in action; and proportioning that influence to the circumstances of the case—motion Is instantly propagated from the sensorium to the point of destination by means of the nerves, unless there be a defect either in the nerves, or muscles, or bones of these parts which renders action impossible. How the nerves act in either of these cases, is not certain. The most eminent physiologists are by no means agreed. The opinion which most obtains“ is, that there is a remarkably fine fluid, called the animal spirits, contained in the nervous system, which receives the immediate impulse of the mind in the brain, and communicates that impulse, by a sort of undulation, to the organ where action is intended to be produced: and in a similar manner form external objects by means of the senses to the brain. How the mind acts on the body, and the body on the mind, has never yet been ascertained, and it is probable, never will, in the present state. The fact is unquestionable, that there is a reciprocal influence by means of the nervous system, but the philosophy of the fact is an * See Cullen’s. Materia Medica; Bell’s Anatomy; Haller’s Physiology. Q 226 ORGANIZED NATURE. —————————————————————— OOO eee THE BRAIN AND NERVES OF THE SAME NATURE. absolute mystery. What greatly increases the myste- rious nature of the nervous system 1s, that the whole appears to be precisely of the same nature through every part of the animal frame, and yet various nerves convey sensations to the mind as different from each other as we ean conceive. Why should one set of nerves convey the sensation of hearing, another that of smelling, another that of seeing, another that of feeling ° Though during their progress from the brain or the spinal marrow, the nerves have but little resem- blance to either, the former being soft and pulpy, the latter solid and inelastic; yet, when they arrive at the part at which they are to act as the organs of sen- sation, they immediately assume the appearance of. the brain. This shows that there is no essential difference in fact, but only in appearance. It is also worthy of remark here, that the nerves no where act as the organs of sensation, but at their extremities, where they are destined to act as such. By pressure or injury on other parts of their course, they feel pain, but it has no resemblance to any of the senses. For instance, we cannot obtain an idea of the scent of arose, unless its effluvia reach the nerve which is spread over the internal structure of the nose, and which is appointed to convey the sense of smell to the brain. Were the same effluvia to come in con- tact with the same nerve in any other part, it would produce no such sensation. So also with the eye. Were the image of an object thrown upon the optic ORGANIZED NATURE, 227 THE NERVES WISELY SECURED, nerve with the greatest possible intenseness, we should not see that image—it must be thrown on the retina in order to be perceived. It is also remark- able, that though a nerve pass through a variety of muscles and organs in its course from its origin to its destination, yet the volition of the mind is never regarded by any of these muscles through which it passes, except the muscle which it is intended to stimulate into action. As the nervous system is of so essential import- ance to both the body and mind, it is reasonable to expect that the same intelligence which devised it will take all necessary care for its security. This is remarkably the fact. All the nerves derive a covering from the pea mater. ‘This covering is exceedingly thick and strong where the nerve is exposed to injury from the action of the muscles; but where it runs through a hole in a bone, or is free from pres- sure, the covering is very thin and delicate. Reasoning from matter of fact, we conclude that the nervous system is wisely adapted to its ends, though we are not allowed to enter into its secret recesses, and contemplate the modus of its action. When a person looks on a time-piece, and observes that it points out with accuracy the hours and minutes of the day, he never questions the suitable- ness of the internal mechanism to produce these effects, though he has never seen it. And when we feel the members of the body acting in subserviency to the volitions of the mind, and the mind receiving Q2 > ~\Y x 223 ORGANIZED NATURE. ————————————————————————— ora THE HUMAN FRAME PROVES THE BEING OF A GOD. impressions and ideas from external objects by means of the various senses, who can dispute whether there be a wise and proper economy within, though con- cealed from our sight? When reason and inquiry are non-plussed and confounded, let us stand still and silently adore. From this description of the external form and the internal economy of the human frame, who can avoid exclaiming, in the language of inspiration, “ It is fearfully and wonderfully made!” This is the pro- duct of a combination of intelligence, power, and goodness, no less than infinite ; and the effect is worthy of the cause. If the study of the human eye were recommended as a cure for Atheism, how overpowering must the investigation of the whole system be, every part of which, even the most minute, is more than enough to demonstrate the being of a God. In the whole we see design, contrivance, adaptation. A final cause is every where contem- plated and kept in view through the whole system of means which is interposed. When the offices to be performed by the various members of the human frame are ascertained, let it be inquired whether the instruments with which man is furnished are not suitable and adequate, and whether better can be imagined, as to their visible structure.

It is obvious, from a consideration of the materials of which the animal system is composed, and the action of its parts, that it must be liable to decay by wear and»exhaustion; it is equally clear that without perpetual supplies of nutriment, destruction would speedily take place. It is therefore reasonable to expectethat the same infinitely intelligent Being who formed thé animal body at first, must have anticipated this consequence, and communicated an organization by means of which the requisite support shall be afforded.

The Mourn, which contains the mechanism for the mastication of food, and reducing it to a state fit for the stomach, has already been described. When the food is sufficiently ground and separated, and softened by the saliva, by the assistance of the tongue it is passed into the @sopHacus, or gullet, through which it enters the stomach. In its passage down, it slides over the mouth of the LaRyNx, or wind-pipe, which leads into the Jungs. But if a single crumb were e a wrong direction, and enter the larynx, casio eedy.death.

It is worthy of remark also, that this valve (the EPIGLOTTIS) is composed of materials which of all others in the animal system are the least liable to disease or injury. If it were a bone it might be broken; if it were a fleshy substance it would be liable to inflammation and various other morbid affec- 232 ORGANIZED NATURE.

The @soPHaAGts is a long muscular canal, ex- tending from the mouth, down by the vertebra, into the stomach; it is supplied with a mucus on its inside, | to afford an easier passage to the food. There is a mechanism which deserves notice in the structure of the cesophagus of man and other animals, as it facili- tates the descent of the food in prevents it from lodging in its pas which compose the differe formed, lie in contrary dire fibres runs downwards in the phagus, and the other concentric, lik these descriptions of fibres allow relaxation to admit the food; but/as admitted, the annular fibres begin to contract from the top. downwards, and by this peristaltic motion the food is forced down into the stomach. This struc- ture and peristaltic motion are observable also in the intestines of animals. That part of the diaphragm (or midriff) through which the oesophagus passes into the stomach, is provided with a remarkable kind of fibres, forming a sphincter, by which this part of the cesophagus is drawn close, like the mouth of a purse, so as to pre- vent the food from returning.

It 1s composed of four coats of a strong membrancous and muscular texture, which closely adhere to one another, and allow of considerable enlargement for the admission of food ; and when empty, contract to very small dimensions.

The stomach is supplied with numerous vessels which open into it, and secrete the GAsTRIC yuicr, which lines the whole of its internal coat. This juice resembles the saliva which is supplied by the mouth and cesophagus, and is of essential impor- tance in promoting digestion. It has been observed that the stomachs of animals differ according to the food on which they subsist. . But the Camex is provided with a remarkable organ, 234 ORGANIZED NATURE.

A number of distinct sacks or bags (in a dromedary thirty of these have been counted) are observed to lie between the membranes of the second stomach, and to open into the stomach near the top by small square aper- tures. Through these orifices, after the stomach is full, the annexed bags are filled from it; and the water so deposited is, in the first place, not liable to pass into the intestines; in the second place, is kept separate from the solid aliment; and in the third place, is out of the reach of the digestive action of the stomach, or of mixture with the gastric juice. It appears probable, or rather certain, that the animal, by the conformation of its muscles, possesses the power of squeezing back this water from the adjacent bags into the stomach, whenever thirst excites it to put this power in action.‘ As a considerable part of the digestion of food takes place in the stomach of animals, it is neces- sary, before I proceed, to consider this curious operation. t Natural Theology, ORGANIZED NATURE. 235 MEANS OF DIGESTION. Sr nai DIGESTION, PL II aL It is obvious that the materials which compose the food of animals must undergo some change in order that the nutritious particles may be separated from those which are not so, and be reduced to a state sufficiently minute to pass into circulation in a fluid form. That which produces this change is called Digestion. ‘This process is partly effected in the mouth, by the food’s being cut and ground by the teeth; it is there mixed with a large quantity of saliva, and brought into a pulpy state before it is dismissed into the stomach, where a great part of this important change is accomplished. There has been a great diversity of opinions respecting the means by which the decomposition of food is effected, Some have thought it is by the sole action of the stomach upon its contents; others have thought that it is cffected by fermentation ;— and others, again, by putrefaction, It is most pro- bable that it is not one of these alone, but their combination, which produces the effect. ‘There is no doubt that a considerable quantity of atmospheric air is combined with the food: by the heat of the stomach this air is rarefied, and consequently, bursts open the cells which contain it; the gastric juice at the same time penetrating between the THE POWER OF DIGESTION SURPRISING. particles, and dissolving them.? A kind of putrefaction also takes place very soon upon some kinds of food. The action of the stomach likewise promotes diges- tion; for besides its own peristaltic motion, it is agitated by the constant motion of the diaphragm every time we breathe.—But by whatever power or powers this process is carried on, its operation is truly wonderful. Few substances resist altogether its energy: this is remarkable in man, and much more remarkable in some other animals. And it is worthy of observation that though the stomach and its digesting powers decompose almost all other bodies, the coats and fibres of the stomach itself remain unaffected as long as they retain the vital principle. Of all the chemical laboratories that were ever constructed, that which is placed in the animal system is the most surprising, as well for simplicity of structure as for power of effect. The process goes on insensibly to the animal, in general, whether it is asleep or awake. The pleasure attending the mastication of food compensates for the labour of it; ‘and Divine Wisdom has so arranged things, that the whole systein is nourished and fed by its own mysterious co-operation without the creature’s further voluntary agency. The stomach, properly so called, has no lacteal vessels, or absorbents, for diffusing its contents into n * Haller, p. 86, vol. I. ORGANIZED NATURE. 237 THE STRUCTURE OF THE LIVER. the system. The cHyME, to which the food is reduced here, must undergo a still further change before it is fit for circulation. When it is sufficiently reduced and decomposed, it is removed through an orifice (pylorus) at the end of the stomach, which is opposite to that at which it entered it by the cesophagus, into the duodenum, which is a part of the intestinal canal® near to the stomach, where it is further reduced to cHYLE, by being mixed with the gall, which is of essential importance to it. The gall is generated by the Liver, which does not subserve any other purpose.—The liver is a large substance of a dark red colour, situated imme- diately below the diaphragm, extended in part over the stomach. In the liver is a small bladder des- tined to contain the gall, which it receives through vessels appointed for that purpose from the lobes of the liver where it is elaborated,—but by a pro- cess which no human skill has hitherto discovered. The gall-bladder is provided with other ducts or vessels for conveying its contents to the place where they are intended to act—this place is the duo- * The length of the intestines has a relation to the nature of the food on which the animal feeds. Carnivorous animals have small stomachs and short intestines, because flesh cen- tains more nourishment than other kinds of food, and is sooner digested, and sooner turns to a state of putrefaction, and there- fore requires to be sooner discharged from the system. ‘The contrary is the fact with regard to those tribes of animals which exist on vegetables. 238 ORGANIZED NATURE. a ci hem THE BILE A SINGULAR COMPOUND. denum.' It there meets with the digested aliments, and readily mixes with them, effecting a still fur- ther change in their state, and, at the same time, communicates an important mucus to the intestines, and assists their peristaltic motion. Its soapy and acrid nature is well adapted to all these purposes. Soda is one of the substances found in the bile of animals. Whenever this alkali: occurs native, it is always in a mild state; and as it cannot’ combine with oils to form soap unless it be caustic, this causticity is given it for these manufactories by artificial means. It is worthy of remark, that na- ture has furnished the bile with soda in the state of causticity, which gives it the property of com- bining with, and soponifying the fat or oily sub- stances taken into the stomach, and rendering them soluble in the other animal fluids. What account can be given of this deviation from the usual course * The manner in which this GALL-pucT enters the duo- denum is remarkable-——The duodenum is composed of dif- ferent membranes. The gall-duct enters the outmost; it then passes along the middle of this coat a short distance, and then passes through.—The reason of this is obvious. The inner and outer membranes act as valves to the two openings, in order to prevent the contents of the duodenum from entering into the gall-duct, where they are not wanted, but where they would prove injurious.—The same contrivance takes place in the bladder where the urine enters it; the object is the same— to prevent it from returning. The mode of action is as ob- vious as in any piece of mechanism, and as clearly discovers design. ORGANIZED NATURE. 239 THE POWER OF DIGESTION DIFFERS IN DIFFERENT ANIMALS, —— OOOO of nature, but the important purpose which it serves in the animal economy ?* The food is now prepared to be converted into blood. —A reflecting mind cannot but be struck with the ease, the ingenuity, and the certainty, with which every thing is done when God is the agent. Every organ is in its proper place—it acts just where its influence is wanted, and neither sooner nor later. Had the gall-bladder emptied its con- tents into the stomach, it would have been highly injurious—but it affords them just where they are required. This observation is illustrated by innu- merable other facts supplied by the animal system. The digesting powers of animals differ widely from each other, both as to vigour, and the ma- terials on which they act. ‘The stomachs of gra- nivorous animals will not digest flesh meat—and the stomachs of carhivorous animals will not digest vegetables, at least, with so much facility. The digesting powers of man form an exception to this general rule,—being capable of digesting, with almost equal facility, both animal and vegetable substances. The stomachs of ostriches, and some other birds, possess surprising powers ;—almost all bodies, whose particles are capable of separation, yicld to their action, except the stomach itself, which remains unaffected.' * See Parkes. : ‘See some remarkable experiments to prove the power of the digestion of some birds, p. 87. - 240 ORGANIZED NATURE, USES OF BLOOD, AND ITS CIRCULATION, THE BLOOD, AND THE MEANS OF ITS CIRCULATION. PLOT ELIE The blood of animals is the principal means of supporting life;—I shall describe its properties, and the machinery which is contrived to give it circu- lation. : : While air, heat, and other bodies, whose action is external, co-operate in supporting life, it is the blood within. to which the food of the animal is con- verted, and which circulates every where through the system, that affords life its principal support. It is this which gives strength and increase to the bones, which feeds the muscles, and administers support to all the other parts of the animal. Withhold food, which is designed to form fresh supplies of blood, and we all know that the animal soon expires. The blood contained in the human body is about thirty pounds. Suppose the number of pulsations to be seventy-five in a minute, and the quantity expelled from the left ventricle, at each pulsation, to be two ounces and a half; the whole quantity will pass through the heart. about twenty-two times in an hour; and it will, therefore, perform the circulation once in less than three minutes. | In the duodenum, and through the whole length of the alimentary canal, there are innumerable fine small vessels called LACTEALS, or absorbents, which are intended to receive, from the digested aliments, ORGANIZED NATURE, 241 CONSTITUENT PRINCIPLES OF BLOOD. those particles that are nutritious. All these small vessels meet together, and form one large canal, (the thoracic duct,) into which they discharge their contents. This new-formed blood is yet in an im- perfect state, and must enter the heart, and from the heart must be propelled to the lungs, in which it derives certain qualities from the air we inhale, and be returned again into the heart, before it is per- fected and fit for circulation. . In examining the properties of blood, we are astonished at the great variety of materials of which it is composed. When taken from the animal it soon divides into two’ parts, the one consisting of red globules called the crassamentum, the other trans- parent, like water, and called the serum. Chemistry has discovered that these two parts are not so simple as at first sight they appear to be. They are found to contain, earth, water, fire, air, sea-salt, iron, oil, and an acid. And if we consider that each of these is not a simple, but a compound substance, containing a variety of different materials, we shall be surprised and confounded. However, this great variety of materials is necessary, in order that the blood may yield to the system its essential support, and afford materials also for the formation of a great variety of other fluids of indispensable importance, and which I shall afterwards mention. 242 ORGANIZED NATURE. ES STRUCTURE OF TRACHEA. eee THE LUNGS. As the lungs of the animal, and the process of respiration, are concerned in the formation and per- fecting of the blood, it is here necessary that I should’ glance at both, in order to show that they are adapted to this purpose. The formation of the lungs has an evident relation to breathing; and the act of breathing as evidently has a relation to the lungs. As the atmospheric air passes through the mouth, down the TRACHEA, or wind-pipe, it is necessary that I should give a brief description of it, before I speak of the lungs. The trachea is a surprising piece of mechanism. As breathing is essential to animal life, it is necessary that the organ through which it is performed should be of such a nature as to admit of its being carried on without any liability to obstruc- tion from common causes. It is therefore not like the cesophagus, or gullet, through which the food passes into the stomach, and whichis a mere fleshy substance. The trachea is cartilaginous; yet it is not made of one continued cartilage, but of several annular ones, hike so many hoops, joined together by strong membranes, which membranes are muscular, composed of straight and circular fibres. Here we see provision made to accommodate it to the bendings of the neck, and the various motions of the head. These cartilaginous hoops are not perfect circles ; jor on the back part, ORGANIZED NATURE. — 243 ORGANIZATION OF THE LUNGS. to a small extent, the circle is filled up by a soft membrane. ‘This is singular; yet the reason is evident. Tor this part of the trachea comes close to the cesophagus, and is intended to allow of that dilation which is occasioned by the passing of the food down it into the stomach. And what affords proof that this was the design of so singular an alte- ration, is, that as soon as the trachea enters the lungs, its cartilages are no longer deficient, but complete circles. As soon as the necessity for the alteration ceases, the rings assume their complete form. ‘The whole of its inside is provided with a glutinous matter issuing from glands provided for the purpose, in order to defend it from the sharpness of the air which is inhaled. The whole is most perfectly mechanical, adapted to a given object, and yet accommodated to contiguous circumstances. Both the cesophagus and the trachea are essential to the system; that system required that they should descend close and parallel, and each accommodates the other, without any injury to itself. Foresight and contrivance are too evident to be passed over without being perceived. By the Lunes are meant that large, soft, and spongy substance which fills the greater part of the cavity of the breast, composed of the infinite ramifi- cations of the trachea. ‘They are divided into several lobes, three of which are usually found in the right side, and two in the left. Here are two different systems of vessels, the one to admit the air from the R & 244 ORGANIZED NATURE. THE OFFICE OF THE LUNGS. trachea, or wind-pipe, through every part, and the other to allow of the circulation of the blood from the heart; in these vessels the blood 1s exposed to the action of the atmosphere, from which it separates its oxygen. The substance of the lungs being spongy, it is remarkably suitable to allow of a vast proportion of vessels for both these purposes, so that a large quantity of atmospheric air may be taken into the lungs, while a considerable proportion of blood may be passing in circulation. . The intention of thus exposing the blood to the action of the air, is not merely to impart to the new-formed blood qualities which it never possessed before, but also to restore the same properties to that which has been in circulation, but which it has lost. It is in the lungs that the blood acquires its red appearance. This is effected by the ferruginous qualities of the bleod absorbing the oxygen gas of the atmospheric air, for which they have a strong aflinity:—this is evident from the unquestionable fact, that the atmospheric air, in passing through the lungs, is deprived of almost the whole of its oxygen, and the blood is found to contain it. This is the principal means of preserving the heat of the body. The structure of the lungs | is sur pxisingly adapted to the reception of an amazing quantity of air. Tor Dr. Darwin supposes that their internal surface, or air-vessels, in man, is equal to the external surface of the whole body, or fifteen square feet: it is on this extended surface that the blood is exposed, through ORGANIZED NATURE. . Q45 THE DIAPHRAGM—BREATHING. the medium of a thin pellicle, to the influence of the respired air. | The lungs, however, considered in themselves, have no power to effect the process of respiration, though we find a suitable structure in them to allow of it. The means of performing this must be looked for in some other organ. This is that membrane which is extended across the thorax, immediately below the lungs and the heart, and spreads over the liver and the stomach, which is ‘called the DrApHRAGM, or midriff. It does not extend across in a plane surface, but forms a kind of vault, the convex side of which is towards the thorax. It is a muscular substance; and by the contraction of its fibres, is drawn nearly into a flat surface in the act of breathing; in consequence of which, an enlargement of the cavity, called the thorax, takes ‘place; the equilibrium between the lungs and the ‘atmosphere is destroyed, and the air forces its way down the larynx, and by filling the lungs, restores the equilibrium: the muscular fibres of the diaphragm relaxing, it returns again to its original state, and at the same time expels the air from the lungs; again they contract and relax, and thus carry on the process of respiration, so essentially necessary to animal existence. In a healthy state of the system, ‘this action of the diaphragm takes place fifteen or twenty times in a minute; and at each inspiration about forty-two cubic inches of air enter the lungs, or almost eight hundred in a tninute, or forty-five 246 ORGANIZED NATURE. STRUCTURE OF THE HEART. thousand three hundred and sixty in an hour; the air imparts its oxygen to the circulating blood, to the amount of thirty-two ounces (troy) in twenty-four hours. From these remarks it is apparent that a most astonishing provision is made for the formation, the perfecting, and the renovation of the blood of animals. But as its presence is wanted in every part of the body, it is obvious that there must be a system of vessels to allow of its circulation, and a machine to put it in motion. These vessels we call arteries or veins, and this machine is the heart. I shall offer a short description of each, and point out the process of circulation. | PLPOL OLDS THE HEART, ARTERIES AND VEINS. The external form of the heart is well known. It is composed of muscular fibres of vast power. These fibres are described as running in all directions, in order to form this essential organ. It has two cavities, which, on account of their external resem- blance to an ear, are called auricles, being in fact, reservoirs to the two ventricles, into which they open, and which are cavities considerably more capacious than the auricles." These auricles and ventricles are called right and left. From the left ventricle pro- ceeds a large circular tube called the aorTa, which m™ The left ventricle of the human heart will contain about two ounces of blood, and the right nearly three. ORGANIZED NATURE. | 247 ARTERIES—VEINS. SS is the main trunk of the arterial system of vesscls, all of which branch from it into every part of the body, and are designed to carry the blood from the heart to the remotest extremities.” In these only, pulsation is discovered. In the arteries are placed valves which open in the direction of the motion of _ the blood; that is, from the heart; their design is to prevent the blood from returning back the same way it came. The arteries are joined to the Veins, which form another system of tubes, just the reverse of the former, designed to convey the blood back again to the heart ; these are also provided with valves which prevent the return of the blood from the heart. As the arterial system commenced at one large trunk proceeding from the left ventricle of the heart, dividing and subdividing into innumerable branches, so the system of veins commences at the termination of the arterial, one vessel opening into another, decreasing in number, but increasing in magnitude, till they all terminate in two, which enter the heart at the right auricle: these are called the vere cava. " The tubes which conduct the blood to the brain have an angular and tortuous course before they branch out on the PIA MATER; which circumstance augments the retarding effect. Every thing, on the contrary, facilitates the blood’s return, and prevents the distension of the veins in the head. The final cause is obvious; for too free an access of blood into the head would be attended with the most dangerous consequences, | 248 ORGANIZED NATURE. PULMONARY ARTERY AND VEIN. Besides these, there is another artery called the PULMONARY, which arises from the right ventricle of the heart, and passes towards the lungs, sending off innumerable branches through the right and left lobes of the lungs: from these branches the veins commence, which, as in the former case, gradually unite, till they terminate in one large opening into the left auricle;—this is called the puLMoNARY VEIN. It would be tedious to enter into a minute description of the structure of these vessels: let it be enough to remark that the arteries are much stronger than the veins; the reason obviously is, that they. may be able to resist the impetus with which the blood circulates through them, and impel it towards the veins. woorerasr THE CIRCULATION OF THE BLOOD. Having with all possible brevity attempted te convey an idea of the apparatus which is. intended for the circulation of the blood, let us now view it in action. But who will say how it is put in motion? Here philosophy is confounded; and though it is resolved into the vital principle, yet this does not explain the difficulty :—for what is the vital principle? and how does it act on this apparatus? These are inquiries which are not to be solved in the present state. However, my business is with matter of fact; this is sufficiently ‘illustrative of the wisdom of the great Creator. ORGANIZED NATURE. | 249 CIRCULATION OF THE BLOOD. The circulation of the blood was unknown till it was explained by Harvey. It is now well under- stood; and I shall attempt to give the reader an accurate idea of it, in as few words as I possibly can. Let it then be observed that the ventricles of the heart admit of enlargement, and consequently of contraction, as well as the auricles. By this struc- ture, it appears in fact that there are two hearts joined, each consisting of an auricle and a ventricle; the one is intended to circulate the blood through the lungs, which is the right; and the other to cir- culate it through the body, which is the left. It is obvious that the force required to promote the lesser circulation,—that is, through the lungs, is much smaller than that which is necessary for the larger, which is to send. the blood through the whole system. And it is a fact which deserves notice, that the muscular substance of the heart, on the side of the larger circulation, is proportionately stronger, containing nearly three times the substance of the other, where but one-third of the power is wanted. | In conveying an idea of the circulation of the blood in the human body, let it be observed, that both the auricles and both the ventricles of the heart contract and expand at the same moment; that is to say, while the auricles are fillmg and dilating with blood from the veins which open into them, the ventricles, which have been filled by the previous contraction of the auricles, contract both together, and discharge their contents into their respective 250 ORGANIZED NATURE. CIRCULATION OF THE BLOOD. arteries. But in order to be distinct, let us imagine that we see the blood flowing through the veins denominated the cavas, into the reservoir called the right auricle, which is filled in about a second of time. When filled, its muscular power is stimulated by its contents, which occasions it to contract and force the blood through an aperture into the right wentricle—this opening has a valve which immediately closes to prevent the return of the blood. Again, the muscular power of the heart being excited, it contracts, and forces the blood into the pulmonary artery, which conducts it through the lungs, when it returns again by the pulmonary vein into the left auricle, which is the reservoir to the left ven- tricle. ‘The coats of the left auricle immediately contract, and force the blood, which is now fit for general circulation, into the left ventricle. |The opening which leads from the one cavity to the other has a valve, as in the former case, which prevents the blood from returning. This ventricle being filled, the powerful muscles which surround it are. sti- mulated so as to occasion them to contract, and to force the blood into the artery called the aorta, through which it is distributed through the whole system, and returned back to the heart by the veins, when it repeats the same circulation. “The wisdom of sthe Creator,” says Hamburger, “is in nothing seen more gloriously than in the heart."—-And how well does it -execute its office! An anatomist, who understood the structure of the ORGANIZED NATURE. 251 BLOOD INTENDED TO SUPPLY THE CONSTANT WASTE. heart, might say before-hand that it would play; but he would expect, I think, from the complexity of its mechanism, and the delicacy of many of its parts, that it should always be liable to derange- ment, or that it would soon work itself out. Yet, shall this wonderful machine go, night and day, for eighty years together, at the rate of a hundred thou- sand strokes every twenty-four hours, having at every stroke a great resistance to overcome; and shall continue this action for this length of time, without disorder and without weariness !° These singular facts, at the same time that they demonstrate the existence of a Supreme Agent, dis- play his admirable skill. What foresight! what facility of contrivance to overcome difficulties! what singular mechanism is employed by him to promote his grand objects! All the constituent parts of animals are undergoing continual changes—soon being rendered unfit for use, the obnoxious particles are separated from the rest, and removed out of the system to which they would otherwise prove destructive. This renders a constant supply of new materials necessary to repair the loss. I have at- tempted to show how this is effected, by tracing the food to blood through the process of digestion.:—by following the blood into circulation, where it imparts qualities to all the different branches of the animal frame according to their respective natures and demands. © See Paley’s Natural Theology. 252 ORGANIZED NATURE. ere er] VARIOUS PROPERTIES OF THE ANIMAL DERIVED FROM BLOOD. = As it was before remarked, every animal is composed of an astonishing diversity of parts, as different in their essential properties as they are in their forms, uses, and appearances. These all de- rive their nutriment from the blood. How asto- nishing must be the chemical changes which it undergoes in the different stages of its progress! How many laboratories, if we may call them so, must there be in different parts of this mysterious system, to separate, to combine, to decoct and filter the fluids before they are fitted to enter those surprisingly minute vessels which are appointed to convey them to their respective places.—QOne part is separated from the rest to support the bones ; another for the muscles; a third for the nerves; a fourth for the humours of the eye; a fifth for the lubricating of the joints; a sixth for the skin; a seventh for the hair; an eighth for the nails; a ninth for the vessels in which the fluids circulate ; a tenth for the gall; -the eleventh for the gastic juice; a twelfth for the tendons. Various others might be named. All these different parts which I have mentioned are so dissimilar, that we should think it impossible they should all derive their existence and support from a fluid of such apparent simplicity as the blood, had we not unquestionable evidence of the fact. By what means the blood possesses these various qualities, or undergoes these various changes, yét remains a secret, and probably ever will.

We live, it is true, in an age of astonishing research and dis- coyery, especially in the science of chemistry ; yet we can hardly hope to unfold these mysteries of nature, or indulge the supposition that future ages will disclose them, It is probable that they will remain secrets in the Divine mind, which if he ever explain, it will be in a higher state of our existence than the present.

It enters the GLanps, in which it undergoes remarkable changes. The glands are a kind of chemical laboratory, placed in different parts of the body as the necessity ot the case requires. ‘‘ They are small, roundish, or oval bodies, formed by the convolution of a great number of vessels, and intended to separate par- ticular humours from the mass of blood.” It is said that they are connected with the ends of ar- teries from which they are supplied with blood: this however, they soon change into other fluids 254 ORGANIZED NATURE. > | NATURE AND OFFICE OF THE GLANDS. which bear no resemblance to it. The Zver is one of these glands, whose office it is to prepare the gall, which is essential to the formation of blood, and to promote the peristaltic motion of the intes- tines ; for it is discharged from the gali-bladder, and mixes with the chyle, in the duodenum. The gall is composed of a large proportion of water, and a vast quantity of inflammable oil.—Another descrip- tion of glands are the breasts, which are to secrete the milk. Milk, when examined by chemical ana- lysis, is found to be composed of oil, mucilage and water, and a considerable quantity of sugar.—There are also the salival glands ; these are situated in various places contiguous to the mouth, where the saliva is wanted in the mastication of food. It is composed of water, a small quantity of salt, and some oil and earth.—Beside these, there are the synovial glands, which are situated adjacent to the joints, being intended to lubricate them with the oil which they secrete, and diffuse all over them.— Various other glands might be mentioned; but a reference to these which I have particularised will illustrate the principle sufficiently, that the infinitely intelligent Creator foresaw all the necessities of the animal, and made a provision to meet them.” Had no contrivances of the above description been devised, the system would have been incom- * For a full account of the glands and secretions, see Haller, vol.

Without the salival glands, the food could not have been prepared for digestion : without the liver, the gall would not have been generated, which is indispensable to the above-named purposes: without the synovial glands, the joints would have become stiff and inflexible: without the glands which are appointed for the secretion of the milk, a nourishment of vast, if not essential, import- ance to the infant race would have been wanting. After all these solids and fluids have been in use in the system for a short time, they become unfit to remain.in it; nay, they would be destructive, if not separated immediately from the more healthy par- ticles, and removed from the mass. By means unknown to us, therefore, this separation is effected, and the obnoxious matter is discharged through the various channels which are destined for this pornos such, for instance, as perspiration. But under the direction of unerring Wisdom, this very excrescence is not to be discharged from the animal system without being subservient to its wel- fare :—for in the very manner in which it is thrown off, it answers an end essential to our being. Per- spiration, or the evaporation of moisture from the surface of the body, is the means by which the blood is preserved in a proper, and nearly an equal tempe- rature: so that the blood of a person who lives in the torrid zone, is only of the same heat with bis who dwells in the cold and dreary regions of Lap- 256 ORGANIZED NATURE. IDENTITY OF PERSON PRESERVED. land:—for this is a fact which is well established. We see here a contrivance for carrying off the super- abundant heat. But this would prove destructive of animal life, were not means provided for supplying heat to the blood, as well as for taking it away. The newly-formed: blood in passing through the lungs acquires a greater capacity for caloric, or the cause of heat: And by the decomposition of atmo- spheric air, which takes place in the lungs, caloric is evolved, and being taken up by the arterial blood, is given out to every part of the body in the course of its circulation. Nothing can afford a more striking proof of creative wisdom than this provision for the preservation of an equable animal tempe- rature. While the identity of person is preserved from the earliest to the latest period of life, a perpetual change is taking place in the materials which constitute the animal organization; so that what constitutes the corporeal frame at one period of our lives forms no part of it at another. Yet while this astonishing revolution is accomplished, we are in a great measure strangers to what is going on; the whole is effected as much without our aid, as it is without our consciousness. Millions of particles are daily added, and as many are abandoned, yet we feel no change—no inconvenience.

What an amazing diversity of materials are employed in this astonishing compound! How many thousand opera- tions are taking place every moment of our existence ; yet there is nothing confused—nothing which clashes : —however numerous the muscles may be which are called into action by one effort, as many more can be excited without any, even the least, obstruction to the former. The bones may be in action; muscles may be contracting and relaxing in obedience to the volitions of the mind, excited through the ner- vous system; the blood flowing in the arteries and veins ; the different fluids forming, and the humours secreting ; the process of digestion proceeding to repair the loss occasioned by the ware of the system’, while we are employed about the various avocations of life which engage our thoughts and attention, or involved in subjects which have na relation whatever to these surprising operations.

SIMILARITY OF ANIMALS, of parts, than in the internal principles of action ‘and renovation. With respect to external form, there is an obvious difference in favour of man, which instantly strikes the eye; but when we enter into the internal structure,—consider the mechanism which is employed, and examine the physiology of animal life, we observe a great similarity in the essential and vital principles. All animals have, for instance, a stomach for the digesting of food, and the means of turning it into blood; a system of _ veins through which the blood circulates, and a heart, or that which answers the same purpose, to put it’ in motion. They have muscles to actuate their limbs, and a nervous system to connect, in a certain sense, their volitions and their powers of action. Thus we recognise the same infinite skill, and boundless goodness in all the diversified tribes of animal existence, and admire the only wise God. Comparing the structure of animals in general, and the human animal in particular, with their modes of obtainihg food, and the actions which they are to perform for the benefit of the general economy, we are astonished at the suitableness of their organs, and the amazing variety in the shape and size of their limbs. In forming this comparison, were we to ask the question, Can any improvement be made,—can any alteration be sug- gested for the better? we are instantly satisfied that the Creator has done all things worthy of himself, and has demonstrated that there is a Bemg whose ORGANIZED NATURE. 959 ORGANIZED NATURE INFERS A GOD. wisdom, goodness, and power, acknowledge no rival, and who, in all respects, is infinitely superior to the most intelligent of the creatures. With such an accumulation of evidence before us of the existence of a God, is it possible that there can be an Atheist in the world? If there ever were such a being who ranked with intelligences of the human race, we are ready to imagine that he must either have been destitute of that capacity of reasoning which is common to the rest of his species, or incapable of applying it; or else have been under the tyranny of an agency whose design it is to degrade and ruin those who are the objects of its operations, or to insult as much as possible the Infinite Spirit. In contemplating design and contrivance, the reasoning mind is naturally led to a DrestGner and a Contriver. To suppose it possible that chance, or a fortuitous combination of atoms, could produce such a thing as a leaf or an animal, would require an astonishing sacrifice of our reasoning powers, and involve us in difficulties far greater than that of admitting the being of a God. But what kind of dereliction of rationality must that be, which would dispose a’ man to believe that the same fortunate combination has taken place in millions of instances; and at length the combination was so happy as to produce such an organization of parts in both vege- table and animal existences, as to enable them to propagate their species in endless succession, and s 2 260 ORGANIZED NATURE.

If there is a God, as all that has been advanced most clearly demonstrates, it follows, that he must not only be infinite in wisdom, but also in power, holiness, and goodness, and therefore worthy of. the supreme affections of his rational creatures. To confess his existence, and to deny him the supreme affections of the heart, and our entire. obedience, appears so preposterous and shocking, that we are at a loss which to deem the worse character,—the man who denies his being, or the man who admits that there is a God, but does not love him. I nich question whether there ever were an Atheist in the world,—one who in sentiment and conscience believed there is no God. I should regard such a being as a most singular phenomenon, and the greatest curiosity in nature. If I were re- quested to discover one, I should not know what direction to take with any probability of being suc- cessful. But if I were requested to point. out those who are practical Atheists, “ professing that they know God, but in works denying him,” I should be at no loss—thousands would immediately present themselves in every gradation of society, from the most poor and illiterate, to the richest and the most intelligent.

Rather than abandon their crimes, they will sacrifice their reason; and forget. the man, in order to indulge the passions of the brute or the fiend. With so many proofs around us of the being and attributes of a God, how astonishing it is that he should ever be absent from our thoughts! How many motives present themselves to excite our al- fections; and how many means are at hand to conduct them to Him, “ in whom we live, and move, and have our being!” “Thou shalt love the Lord thy God with all thine heart,” is as well the lan- guage of nature as it is of revelation; and no man has examined the sacred pages of either to much purpose, whose soul is supremely engaged in earthly pursuits.—But of all the attractive discoveries which the Most High has ever made of himself to man- kind, that which he has given them in the person of his Son, is the most powerful and engaging. Here is the most stupendous display of wisdom, and all the natural perfections of Deity, in connexion with his mercy, and those which we term moral. “Mercy and truth meet together, righteousness and peace embrace each other.” Here he appears with overpowering charms; and we scarcely know which to admire the most,—the justice which required the satisfaction—the wisdom which contrived the means of and then they 262 ORGANIZED NATURE.

The Author of our Being is the Author of our Redemption: and whether we regard him in the one character or in the other, or in both, we must be struck with the most invincible arguments to destroy the native in- fidelity of the human heart, to elicit the warmest affections of rational creatures, and to induce a cheerful and prompt obedience to his name. It was intimated before, that the curious taber- nacie which I have been attempting to describe, is destined to be the residence of a still nobler being, a being of a far superior order—I mean the Sout, whose peculiar nature and characters I shall now consider, with a view to develop the same wisdom which appears so conspicuous in all the forms of organized matter.

We can conceive of but two descriptions of existences in the universe, to which all the infinite varieties are reducible; the one we denominate ma- terial, the other immaterial, or spiritual. The former order of existences I have already considered under a two-fold representation; that is, as being either organic or inorganic. I shall now direct the attention of the reader to those beings which are spiritual, and formed for an immortal existence. The highest description of spiritual beings is God himself, who is the Creator of all other existences, whether they are purely intellectual or endowed with corporiety. Next to him are angelic natures. All ‘the universe proclaims a God; but it is to divine revelation entirely that we are indebted for our know- ledge that there are beings which we call angels. Though revelation speaks of them as spirits possessed of great power and wisdom, yet it says but little respecting their essential natures, and dwells prin- 266 INTELLECTUAL BEINGS. BRUTE ANIMALS HAVE MIND. cipally on their employment in the government of God. We have reason to suppose that there are two kinds of immaterial existences which are united to material bodies in this world; I mean those which belong to brute animals, and those which are peculiar to the human race. To deny that brute animals have souls, is virtually to allow that matter can think; and to put an argu- ment into the mouths of materialists which it will not be easy to rescue from them. To ascribe all the actions of brutes to the principle which we call instinct, is to attempt a distinction between that principle and. reason, where no essential difference can be pointed out; for the resemblance is so strong that it is impossible to say at what point instinct stops and reason begins. ‘To deny that brutes think, that they possess powers of recollection, and that they have a variety of passions, would be to deny unquestionable facts. If matter can do all this, why not, under a more refined modification of it, do all that we discover in the human race? But when I allow that brute animals possess mind or spirit, I by no means grant that they are immortal:—no; for after all that has been said to demonstrate that spirit mus¢ in its own nature be immortal, I am convinced that the reasoning is inconclusive. . While I conceive that there is a suitable adaptation to an immortal existence in the structure of mind, it appears to me that it is immortal because it is the will of God that it should be so. Iam therefore of opinion that the souls of {INTELLECTUAL BEINGS. 2067 MAN POSSESSES AN IMMATERIAL PRINCIPLE, brute animals perish at death, whilst those of the human race exist for ever,—not because their nature is essentially different, but because God has decreed the destruction of the one, and the immortality of the other. This I imagine to be the legitimate basis on which immortality rests. My object at present is, to describe the structure of the human soul. It is not intended to enter into a minute and metaphysical analysis of its nature; but only to consider it so far as it is illustrative of Divine Wisdom. ‘The intelligence which is discoverable in the structure of the human mind, is indeed not so obvious as it is in the formation of organized matter; we. cannot see the mechanism of its parts, nor their adaptation to a given end, so clearly; for it is difficult for us to turn our attention so forcibly upon our own minds as to give them such a kind of imaginary visibility to our perceptions, as to obtain accurate ideas of them. Yet it is probable that mind contains as great a discovery of wisdom as any other object of creative power whatever, of which we should be thoroughly convinced, if it could be examined in the same manner; but this is impossible from the nature of the thing. That Man possesses a something besides, and really different from matter, can never be questioned, except by those whose minds are under the influence of a skepticism which leads them to doubt of the most certain truths. Whether the Creator could or could not give matter such a modification as to make 268 INTELLECTUAL BEINGS. MATTER NOT CAPABLE OF THINKING. it think, is not the question :—but have we any reason to suppose that he has done it?-—I know but of two methods of answering this inquiry; the one is by appealing to our knowledge of matter, and the other is by referring to the testimony of divine revelation. From our knowledge of the nature of matter, have we any reason to suppose that any part of it has been so modified or organized as to produce thought, a capacity of reasoning, recollection, and other effects, which we usually call mental? I am of opinion, that our present knowledge of matter will not justify us in saying that it does think. Hence, to maintain that matter thinks, without pointing out and demonstrating such qualities in matter, and such an arrangement of its particles as justify the con- clusion that thought will be the effect, is begging the question, and is false reasoning in philosophy ; for it furnishes a conclusion which there are no data to warrant. Such a mode of reasoning would not be allowed on any other philosophical or metaphy- sical subject. To assert it as true, merely from the POSSIBILITY of the thing, is a kind of presumption which cannot be admitted. The persons who have maintained this theory, from a conviction that the seat of reflection is the cranium, have asserted that the brain is that species of matter which thinks ; but as the nervous system is of the same nature as the brain, taking its rise from it either in the cranium, or in the spinal marrow which is only an elongation of the brain down the vertebra, extending over the INTELLECTUAL BEINGS. 269 SSS SSS SSS ES THE SOUL OF MAN IMMATERIAL. —eSSSSSSsSSSSS8S8808080800808S080S SS whole animal frame,—why not think as well at our finger’s-ends, or at our toes, as in the head? Besides, have any of the materialists ever attempted to de- monstrate an organization in the brain,. which we should at all suppose capable of producing thought as the effect of its operation? By no means. And yet, being determined to believe that there is nothing but matter in the human being—and as they can discover nothing but matter in the cranium, the seat of thought,—therefore they infer that matter thinks, — a kind of reasoning which, were it referred to any other subject, would be treated by these philosophers themselves as sophistical and illegitimate. As our present attainments in philosophy, and our knowledge of matter, by no means enable us to prove that matter thinks, let us appeal to divine revelation as the only authority capable of affording a decision. If we place that confidence in the testi- mony of the Scriptures which is worthy of a divine revelation, our conviction will be complete. In multitudes of instances, this revelation speaks of soul, spirit, and mind, as existing in man. To quote these passages would be to crowd my pages with a string of Scriptures which must be in every one’s memory who has read the oracles of God. But there are many other passages. which are of a more decisive character, and speak of spirit, soul, and mind, as being of a nature different from body, and existing separate from it; as, for instance, Acts vii. 59. “Lord Jesus, receive my _ spirit.”—Eccles. iii, 21. 270 INTELLECTUAL BEINGS. SPIRIT ESSENTIALLY DIFFERENT FROM MATTER. Pca RTT a PT I SSS SS TS ESD EP ‘Who knoweth the spirit of man ?”—xu. 7. ‘“ The spirit shall return unto God who gave it."— Gen. ii. 7. ‘‘ Jehovah breathed into man the breath of life, and man became a living ‘soul.” ‘The apostle speaks of “ spirit, soul, and body ;”—of being “ absent from the body, and present with the Lord.”—What was it of Lazarus which angels carried to Abraham’s bosom? not surely his body,—that died and was buried. It must have been his soul, or nothing. What was it in the thief which Christ promised should be with him that day in Paradise? not surely his body, for that died on the cross. ‘‘ Fear not them which kill the body; but rather fear Him, who after he has killed the body, can cast both body and soul into hell.” I might add many other testimonies equally clear and decisive. If these prove any thing at all, they prove that man is a compound being, constituted partly of body which is material, and partly of mind which is immaterial. When I have demonstrated the immateriality of the human soul, I by no means conceive that I have proved its immortality. It no more follows that the soul of man is immortal, because it is immaterial, than that the souls of brutes are so, allowing them to _ be spiritual. To establish this, we must refer to other data; and the only data on which we can rely are such as are afforded by divine revelation. The ancient philosophers remained in a state of entire uncertainty on the subject; their various speculations and reasonings could carry them no higher than INTELLECTUAL BEINGS. 271 THE SOUL OF MAN IMMORTAL. vague hypotheses, and suppositions of a very doubtful nature.. A divine revelation was of the utmost importance to put. this subject beyond a doubt, that mankind might have the full force of this motive daily before them; for what motive so powerful to excite to holiness of life as the full evidence of eternal misery on the one hand, as the reward of sin; and everlasting happiness on the other, as the result of holiness? What the reasonings and surmises of heathen® philosophers could never discover, divine revelation has rendered morally certain; ‘ for life and IMMORTALITY are brought to light by the gospel.” It teaches us that as soon as the soul is separated from the body, it enters on a state of happiness or woe. ‘The resurrection shall re-unite the bodies and spirits of the departed, when the righteous and the wicked shall have their condition fixed for ever ac- cording to their respective moral character. With regard to the wicked, it is declared that they shall go into ‘ everlasting punishment”—‘ where the smoke of their torment shall ascend up for ever and ever” — “where the worm dieth not, and the fire is not quenched ;”"—“ these shall be punished with ever- lasting destruction from the presence of the Lord.” These passages prove the immortality of the wicked. But the righteous “shall go away into everlasting life,” —‘so shall they ever be with the Lord :”—their happiness is called an “eternal weight of glory’— “a crown of glory which fadeth not away.”—“ Eternal life” is promised to those ‘who seek it by patient 272 INTELLECTUAL BEINGS. THE SOUL OF MAN IMMORTAL. ——————— SSS continuance in well doing :"—it is called “ glory and immortality.” These quotations prove the immor- tality of the souls of the righteous. It is one of the most interesting views that we can take of the human being, to consider him as compounded of body and spirit, and destined to live for ever in a state of perfect felicity or complete misery. However much we may admire his: cor- poreal structure, yet if we suppose him possessed of nothing more than mere corporiety, and “that he - terminates his career at the grave, we shall feel a sort of indifference in contemplating his actions, and in following him to his last home. But when we consider him possessed of a spiritual nature, formed with vast capacities for suffering and enjoyment, and destined to an everlasting existence in happiness or woe, according to his moral character, and his conduct in his probationary state in this world, it excites the liveliest concern in our minds,—all is grand—and im- portant. This view of man is at once calculated to strike dismay into the hearts of the profligate, and to restrain them from crime through fear of a punish- ment to come; whilst it gives a peculiar energy to piety, by inferring its connexion with future glory. Man ranks in importance with angels themselves. Of all the creatures of God in this world, it is evident that man ‘is far the noblest. All the rest of the creatures are subservient to him; and either directly or indirectly render him their homage and their aid. He only was made in the image of God, INTELLECTUAL BEINGS. 273 and allowed to approach the throne of his Creator, who set him over the works of his own hands, and gave him “dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.” The great designs of God in bestowing on man intellectual endowments, or a rational soul, were, that he might glorify and enjoy his Creator, by serving him, by contemplating his wonderful works, and by discharging the duties which he owes to those of his own species, as well as to the inferior animals. To do these things, it is obvious: that intellect is essentially necessary; for it demands thought, reasoning, and all other mental operations: and if we describe the human soul in its various attributes and capacities, it will be found to have received a structure (if I may say so) which discovers the same unerring skill that appears in the other works of God. . To render this subject at once lucid and interest- ing, I propose, First, Zo describe the Powers of the Mind;—Srconvuiy, To state the Nature of the Passions ;—Tuirpiy, Yo consider the relation of both to the Corporeal Senses ;—and, Fourruty, To show their adaptation to Religious Exercises, and a Future State.

GFL PEPLLL I shall rirstr attempt a brief description of the powers of the human mind.—When we speak of the powers or faculties of the soul, we do not mean to represent it as divided into different members as our bodies are.—No. ‘That spiritual substance which we call soul, or mind, is one and indivisible, and not capable of receiving any such modification as the body. Therefore, when we speak of its powers, such as Will, Memory, &c., it is only to represent the soul as willing, and remembering, or performing those dit- erent acts which we denominate thus for distinction’s sake. A close attention to the operations of our own minds, I think, will prove that, however rapid their transition from one subject to another, they are incapable of being'employed on two subjects at one and the same moment of time:—as, for instance, while the soul is engaged in an act of remembering, or recalling a past idea or event, it cannot at the very same instant be employed in an act of willing. And yet the rapidity with which it passes from one exercise to another is almost imperceptible, and is hardly ever observed by the mind itself. The celerity of its movements is a compensation for the want of ability to perform two or more different operations at the INTELLECTUAL BEINGS. 275 ae eee THE UNDERSTANDING. ‘ a same time. Having made these remarks, I shall proceed to glance at each faculty of the soul, in order to show what wisdom God has manifested in this extraordinary existence. Let us begin with the Unprerstanpin&G. No- thing is more certain than that mind possesses’ a power of perception, or acquiring a knowledge of those objects which present themselves to its atten- tion. The understanding is the eye of the mind. It is the visual faculty of the soul. It is the repository in which are stored all the ideas and notions of the objects, the events, and the subjects, which offer themselves to our consideration. God’s understand- ing is infinite: He has the most perfect perception of every thing which exists within the compass of the universe. Hence, the apostle elegantly remarks, “all things lie open and naked before the eyes (that is, the mind) of him with whom we havé to do.” This power as possessed by angels, those mighty beings which excel in strength, must be vast indeed, dwelling in his presence, employed by the Deity in conducting the moral government of the world, and basking in the beams of uncreated light. Man, in his primeval state, before sin beclouded his intellectual hemisphere, had powers of perception, perhaps but little, if at all, inferior to theirs. Weakened and injured as they even now are, in consequence of the existence and operation of sin, they are yet capable of surprising efforts. Angelic minds seem to have sometimes dwelt in T 2 276 INTELLECTUAL BEINGS. WISDOM JIS APPARENT IN DIVERSITY OF TALENTS. Se human frames; as in the person of a Newton, a Locke, anda Bacon. At our birth, the mind has been compared to a sheet of white paper, because destitute of all ideas and notions; but though ori- cinally thus destitute, it has a capacity to receive ideas, as white paper has of receiving the characters which may be written upon it. Divine Wisdom appears as well in the astonishing diversity of capacities which is found in different minds, as in this power of receiving ideas themselves. Though much may be owing to the circumstances under which we are educated, yet it appears. that there is a radical and essential difference of capacity and disposition with respect to the same subject. For instance; one person has a surprising aptitude for learning the languages, which another cannot learn but with the greatest difficulty. As the machinery of civilized society is composed of various parts, all of which differ from each other, though all have a mutual relation, and are necessary to the whole; so it is with respect’ to their mental capacities and propensities. Some have a love to the sciences; having capacities to perceive and understand the truths which relate to astronomy, chemistry, botany, optics, physics and metaphysics, and philosophy in general. Other minds are adapted to commerce, and the business of life. Others, again, have an affinity (af I may so call it) for the fine arts, such as painting, sculpture, and music. Thus a pleasing variety is INTELLECTUAL BEINGS. 277 THE MEMORY. produced, while the whole co-operate in promoting the general interests of social order. “ The hand of Nature on peculiar minds imprints a different bias, And to each decrees her province in the common toil : To some she taught the fabric of the spheres ; the changeful'moon ; The circuit of the stars :—the golden zone of Heaven to some she gave, To weigh the moment of eternal things ; of time, and space, And fate’s unbroken chain,—and will’s quick impulse.” AKENSIDE. In consequence of this diversity in the perceptive principle, and an aptitude to receive knowledge of various kinds, the works of God are more completely explored, and therefore he is more glorified than otherwise he could have been; greater harmony 1s preserved in society; the pleasures of social life are increased ; and that dulness is: prevented, which must have existed in a world where all its inhabitants possessed the same mental propensities, and were pursuing the same track of knowledge. Memory is the next faculty of the mind [ shall mention. Had the soul been created without a power of retaining its ideas, a capacity of receiving them had been useless as to any of the purposes of life. The mind would have been like a sieve, and would instantly have lost what it had gained. How the ideas and notions of things, which we receive through the senses, make such an impression on the brain or the substance of the mind, that they may be recalled, and reviewed for» many years after, is a mystery in nature which remains yet unfolded. But the fact is unquestionable. A sound, made by the 278 INTELLECTUAL BEINGS. MEMORY A SINGULAR FACULTY. vibration of the string of a musical instrument, falling on the tympanum of the ear, makes such an impres- sion on the mind as to be distinctly recollected for a long time afterwards. A fact related, will be remem- bered in all its various circumstances, as to the person who told it, the place, the company present, the voice and cadence of the speaker, his looks, the impression which it made on the mind, the kind of feeling it produced, and a thousand other little cir- cumstances, for half a century. An object that 1s seen is instantly portrayed on the mind in its appa- rent magnitude, its shape, its position, its colour, its component parts, &c. so as hardly ever to be forgotten. And it greatly increases our astonishment when we consider, that thousands of objects and subjects may crowd upon the mind in the most rapid succession, for many years, and yet, a person possessed of a retentive memory will take a minute retrospect of his life, and recall almost every thing of which he had obtained an accurate idea at the time, and which had taken place in the ‘compass of a life of seventy or eighty years. Some persons, after reading a book, or hearing a long and argumentative oration, or listening to a great number of speakers, will reca- pitulate not only almost every thought, but nearly every word. We cannot conceive how mind could have been formed by the Creator without this power, so as to answer either the purposes of the Creator himself, or the ends of human existence. What would be a INTELLECTUAL BEINGS. 279 THE JUDGMENT. compensation for its absence? Imagine the most learned man that exists to be deprived instantaneously of his memory, and the same moment you would see him reduced to absolute infancy as to the state of his mind. Such instances have actually occurred, in which the mind has been bereft by disease of its power of recollection, and the same mental vacuity has been observed as exists in the new-born babe. While an attention to this truth should excite in our hearts the most lively gratitude to God for the bestowment of a faculty of so vast importance to mental cultivation, and the pleasure of mental employ- ments, it should inspire us with a deep conviction of our dependence on Him for its continuance and pre- servation. He who has bestowed it, can as easily take it away. Mind possesses a third power, which we denomi- nate the JupGmMENT. It is by this that we associate two or more of the ideas or notions which we have obtained, and by comparing them with each other, deduce a certain conclusion. ‘To illustrate this state- ment.—If we would determine whether it is proper that we should take a certain journey, we bring under our view the circumstances in which we are placed, the object we propose to accomplish by it, the nature of the journey itself, the expenses of travelling, the dangers attending it, the means of safety, &c.; and by comparing them with each other, and considering them in thejr mautual connexion, we come to a con- clusion as to the propriety or impropriety of taking it. 286 INTELLECTUAL BEINGS. THE IMPORTANCE OF KNOWLEDGE. In this case we are said to exercise our judgment. This is, in fact, a process of reasoning. _ The judgment depends on the knowledge de- posited in the understanding, and the accuracy and facility of recollection, for the propriety of its ‘de- cisions. If the understanding be furnished with false or erroneous ideas and conceptions, such will be the materials that the memory will supply from which to form a decision; it will follow of course, that our judgment will mislead us. © If the premises be false, however correct: our reasonings and deduc- tions from. these premises, the conclusions ‘will be false too. If, for example, I am informed that a certain poison is wholesome food, I eat it under this supposition, and judge that it will afford me support as other wholesome diet does; and my.error is my destruction. On the other hand, had my under- standing been accurately informed, and I had known that this substance was poison, I should have rejected it with horror. As it is necessary that we should have ¢rue ideas in our minds in order that we may form an accurate judgment, so the correctness of our judgment will depend on the extent and accuracy of our information. If it be known that our minds ‘are ill-informed on the subject on which we ofter our judgment or opinion, it will be treated with indifte- rence, though it should happen to be right, because it is more likely to be wrong... On the other hand, if we have made any given subject that of our attention,— if our minds are well acquainted with it in its nature; INTELLECTUAL BEINGS. 281 ——ooIIIIeeeeooooooleleEeee—=E—eee—eeEeeeeeeEeEe——eEeEe a aa NR aT RM aa oer re a IMPORTANCE OF THE JUDGMENT. its bearings, and its connexions, — our opinion will be treated with deference, if it be not considered an authority. In conducting a process of reasoning which issues in a judgment or decision, it requires the exercise of the memory to bring forward the stores of the mind: for as no man can reason on any subject unless he possesses some ideas respecting it, so these ideas can be of no service unless they are present to the mind at the proper moment when they are wanted. If, there- fore, the memory be prompt and faithful in bringing forward the appropriate ideas as they are required, the mind reasons well, and is accurate in its decisions. Hence it follows, that, as a sound judgment is of the utmost importance in all the concerns of life, and as extensive knowledge and a correct and vigorous memory are of essential necessity in order to it, it is the. bounden: duty, as well as the interest; of every individual: to cultivate both these attainments, as far as time and opportunity will allow. This faculty is of the utmost importance in all the concerns of rational and intelligent creatures. ‘No man is placed in such a situation as to render the exercise of his judgment unnecessary. Without it, man is a iere idiot. In every concern of life, in every rank of society, from the lowest labourer and. mechanic, to the statesman and warrior, this power is of indispensable moment. As man is a social being, and, on account of his connexion with other beings, owes them various duties; we ought 282 INTELLECTUAL BEINGS. ' THE WILL. greatly to admire the wisdom of God in endowing his mind with a faculty so admirably adapted to all his necessities and obligations. Man is but an impotent being. He can do little, comparatively, by the direct exertion of his corporeal energies ; yet, by the aids of his. judgment and inventive powers, he can accomplish wonders. Apparent accident has started a vast variety of important principles; but it is by the aids of the human judgment that these principles have been combined and improved—that the mechanical powers have been formed and applied to the useful purposes of life, by which feeble man possesses a strength and an importance a thousand times beyond what he would otherwise have attained. I shall, in the next place, consider the Human Wityt. Locke and Epwarps, the. most eminent authors who have written on metaphysical subjects, define the will to be, that faculty ofthe soul by which it is capable of cHoostnG :—an act of the WILL is the same as an act of choosing or choice. Man, without this,: would be only a motionless and useless machine: however well made for a variety ‘of purposes, he would never attempt any thing but as he is impelled by some external agent.—Deprive him of this self-governing principle, and man can be no longer regarded as an accountable being, or a being of importance in the moral government of God. The operations of the will are determined by the understanding. What the understanding views INTELLECTUAL BEINGS. 283 ee THE WILL CONNECTED WITH MUSCULAR POWER. —————eee ESE as good and suitable, the will chooses —what it regards as evil, and prejudicial to our interests, the will rejects. This truth furnishes a conclusion of the utmost moment; it is this:—That a well-informed understanding, enriched with knowledge, clear and accurate in its perceptions, and free from error in the general concerns of time and of eternity, is what all mankind should most ardently seek; for an error in the understanding will be followed by an error in our choice, which may issue in results unutterably tremendous. This faculty seems to have an immediate con- nexion with the cause of muscular motion in the animal creation, so far as that motion is voluntary, or at the control of the animal. Whatever actions the understanding judges beneficial to be performed, the will immediately carries its convictions into effect by stimulating the nervous system, and thus pro- ducing muscular motion, and the actions desired. The virst motions are not subject to the govern- ment of the will,—such as the circulation of the blood,’ and respiration ;—these actions con- _ tinue, whether we will or not. He who gave them has alone a right to suspend them. But all the muscular motions of the limbs, and those organs of the body which have a relation to the duties of life, a discharge of which is involved in our responsibility to God, are under the government of the wit1. This is a fact which well deserves our consideration, © 984 | INTELLECTUAL BEINGS. INFLUENCE OF THE WILL. Were we to reflect attentively on the activity of this power of the mind, we should be filled with constant surprise. We should regard as its effects every motion of the head, and the lips, and the eye-lids; every action of the hands and the fingers:—it communicates motion to the fingers that hold the pen with which I am writing, and directs that motion too, under all its variety ’ of inflections observable in the shape of the’ letters which I make:—it actuates the various muscles which are called into exercise in looking, speaking, and walking—it influences my every action. To the Will is intrusted the executive government of this microcosm—for such is man; a world in minia- ture. With what amazing velocity and energy does it act! With what astonishing promptitude does it obey the dictates of the understanding, and with what celerity does it transmit its decisions to every, even the remotest corner of its dominions! Its energies are always in unison with what is deemed necessary in regard to the strength to be exerted. Whether the hands have to raise’ a pound ‘or ‘a hundred weight, the impulse which the will gives to the muscles to be employed is in that proportion. Is some danger perceived ‘at hand?—with what activity do we attempt to escape it. ‘Is a blessing to be secured :—with what readiness do -we grasp. it. So far as it has to do with mental operations, it discovers equal vivacity.

Every man is a free agent; that is, he is at ‘perfect liberty to do, or not to do, that. which APPEARS TO HIM the best. ‘This is essentially ne- cessary to his responsibility for his actions. Nothing could be more absurd than to make a being account- able for actions which he is compelled to perform, or reward him for actions which he performs from a necessity of nature. Hence, no man is punishable, either by the laws of God or of man, for those crimes which he is compelled to.commit, or _re- wardable for those good deeds which he is neces- sitated to do, contrary to his will. This freedom extends as well to the concerns of religion, as to actions of a civil nature—in both we are free to ~ choose, or to reject, that which appears to us good or evil.—All the operations of the will are determined by the dictates of ‘the understanding: if any man be asked, Why. did you will to do so, or so?—he replies, Because I preferred it.— While I maintain these. principles, I by no means intend. to insinuate that any fallen sinner will choose that which is spiritually and morally good in the sight of God,. independently of a divine agency. Lett to, himself, ‘depraved man will reject that which is spiritually good, and choose that which is in unison with his sinful nature; but he does both freely—he feels no compulsion. Such is the blindness of his heart, that. 286 * INTELLECTUAL BEINGS. THE CONSCIENCE. he sees nothmg im divine things which determines his choice in their favour; but, on the other hand, imagines he discovers, in the sinful objects of his preference, that which will conduce to his happiness. It is true, that man in his sinful state is destitute of a perceptive power in his understanding which biases him in favour of those objects which are holy, and which belong to his salvation; but this defect is his crime. Man originally possessed a spiritual illu- mination whereby he was as much prepossessed in his understanding, and consequently disposed in his will, towards that which is good, as he is now in favour of that which is evil. But this he lost by his voluntary apostacy; hence his spiritual blindness is his crime and not his excuse. ‘That economy of salvation which God has devised, and made known in the gospel, is adapted to the nature of the human mind, as well as to the moral state of man as a sinner. It is an eco- nomy of light. God has granted a revelation which is calculated to illuminate the mind; and he has pro- mised a divine agency to render it efficient. When by the worc and spirit of God, the dark soul is irra- diated to perceive the divine excellency of spiritual things, the will as freely makes choice of a Saviour, as it before set him at nought. Still, man is free. The religion of the gospel is in perfect unison with: all the principles of free agency. I shall now notice the Conscience. In com- mor language we speak of the conscience in distinction from the judgment, though, metaphysically speaking, INTELLECTUAL BEINGS. : 287 NECESSITY OF A DIVINE REVELATION. they are the same thing. However, by judgment, we mean that power of the mind by which.we form our estimate of things in general; and by conscience, we mean the estimate which we form of ourselves in particular. LocKxe defines conscience to be “our own opinion or judgment of the moral rectitude or purity of our own actions.” The accuracy of its operations depends, like the judgment, on the extent and accuracy of our knowledge. Though there may be an innate principle left in man, which, in the general, will discriminate between right and wrong; yet nothing is more obvious than that it is liable to be greatly misled by education and habit: for what in one country is obnoxious to the dictates of conscience, in another appears even right. This infers the necessity of a divine revelation which shall contain an exhibition of the principles of moral rectitude, derived immediately from the mind of God. His will must necessarily be right in all things; and as divine revelation must be in unison with this will in all its prohibitions and injunctions, it forms a criterion to which every nation may appeal, and every action may be brought. So far as our actions accord with it, they »ust be right; so far as they deviate, they must be wrong. Such a revelation must continue unalterably the same in all ages; for what God declares to be morally right or wrong at one period, will be so at every period: what it reveals as being just or unjust in one charac- ter, must be so in every character. It cannot be, like 288 INTELLECTUAL BEINGS. REVELATION RECTIFIES THE ERRORS OF CONSCIENCE, the conscience of a fallen sinner, mutable and liable to be corrupted. A merciful God HAs granted this revelation. On examining it, we find that it con- tains the principles of eternal truth. No advance- ment in man towards a superior state of being, can endanger its principles: they are recognized in heaven among the angels of God, and the spirits of the just made perfect. ‘This book is adapted to universal circulation; it is applicable to the bar- barian and the civilized. Wherever it is received, it produces a unifermity of sentiment and conviction with respect to all the grand principles of equity; and these principles, it is obvious, are those of reason, of justice, of truth, and of benevolence. However depraved the conscience may be, there is something still remaining which justifies all the moral claims and prohibitions of the word of God. What ~ is enjoined there which any man can say he cannot conscientiously perform ? As it is one important object of this revelation to rectify the errors of conscience, by enlightening the human understanding, and furnishing infallible | data to aid our reasonings, how important is it that it should be universally diffused, and. that the educa- tion of every human being should be conducted on its principles.-—So far as its maxims are written on the heart, men learn to do to others whatsoever they would that others should do unto them — justice triumphs over dishonesty—and happiness takes the place of misery. INTELLECTUAL BEINGS: 989° ; THE POWER OF CONSCIENCE, | ee eR A Peele ~The power of conscience is astonishing. Many instances might be adduced to illustrate its invincible energies. I need mention but a few; some are selected from the Scriptures, others are furnished by profane history.—It was conscience which told Adam that -he was naked and guilty, and which induced him to attempt to hide himself from. the presence of God:—which filled Cain with horror and despair while he heard his brother's blood crying against him:—which made David agonize when Nathan said, “Thou art the man:’—which drove those from the Redeemer’s presence who had criminated the woman taken in adultery :—which filled Judas Iscariot with such horror and anguish, that, no longer able to endure his own existence, he went and hanged himself :—which obliged Herod, that fox, to justify the preaching of John, though it condemned his own impious conduct:—and_ it was this which made Felix to tremble while he was hearing Paul reason of righteousness, temperance, and judgment to come. It is the office of con- science to commend the truth, as well as to reproach for crime. | | Profane history supplies various instances illus- trative of the power of conscience.—The inhabitants of a certain town offered Marshal de Turenne one hundred thousand. crowns upon condition that he would take another road, and not march his troops their way. He answered them, “As your town is not in the road I intend to march, I cannot accept U 290 INTELLECTUAL BEINGS. EEE INSTANCES OF THE POWER OF CONSCIENCE, the money you offer me.’—The Earl of Derby, in the reign of Edward the Third, making a descent in Guienne, carried by storm the town of Bergerac, and gave it up to be plundered. A Welch knight found in the receiver's office so great a quantity of money, that he thought himself obliged to acquaint his general with it, imagining that so much money naturally belonged to him. But he was agreeably surprised, when the earl told him with a cheerful countenance, that he wished him joy of his good fortune, and that he did not make the keeping of his word to depend upon the great or the little value of the thing which he promised.—In the siege of Falisci, by Camillus, a Roman general, the schoolmaster of the town, who had the children of the senators under his care, led them abroad under the pretext of recreation, and carried them to the Roman camp, saying to Camillus, that by this artifice he had delivered Falisci into his hands. Camillus, abhorring this treachery, observed, ‘‘ That there were laws as well for war as for peace; and that the Romans were taught to make war with integrity no less than with courage.” He ordered the schoolmaster to be stripped, his hands to be bound behind his back, and to be delivered to the boys to be lashed back into the town. ‘The Falerians, formerly obstinate in resistance, struck with an act of justice so illustrious, delivered them- selves up to the Romans, convinced that it would be far better to have the Romans for their allies than their enemies.—A jeweller, of good character and INTELLECTUAL BEINGS. 291 CONSCIENCE RETAINS MUCH POWER. _ a great wealth, was murdered by his servant, while on his journey, who escaped with a vast property which he thus obtained, and fled into a distant part where he was not known. He began to trade in a low way at first, but gradually enlarged, and succeeded so well as to acquire importance in the town where he lived ; and rising from one office to another, he was at length chosen to be the chief magistrate. Here he continued to fill his office with much credit, till one day he had to try a criminal who was accused of murdering his master. The prisoner was found guilty. The judge appeared much agitated, and to the great astonishment of the assembly, he came from the bench and placed himself by the wretch at the bar, and confessing his own guilt, said, “ Nor can I feel any relief from the agonies of an awakened conscience, but by requiring that Justice be forthwith done against me in the most public, and the most solemn manner.” Sentence was passed upon him by his fellow judges, and he was accordingly executed.* . As man is formed for society, but awfully prone to various evils, the wisdom of his Creator is remarkably apparent in implanting in his bosom this inextinguish- able principle; and notwithstanding the dreadful consequences resulting from the apostacy of our first_parents, it retains much of its original vigour. How much it has lost by sin, we cannot say,—nor how much it retains, though the instances which I pe nih Sea “See Encyclop. Brit—the word Conscience. u 2 992 INTELLECTUAL BEINGS. Mee Akeley ee “THE RESTRAINTS OF CONSCIENCE. z= have mentioned, show that it possesses great power. Of all the faculties of the mind (if it may be called a faculty), this is one of the most important.— Wretched as this world is, how much more so would it be, were it not for the operations of conscience. Hurried on by the mad impetuosity of sin, men per- petrate innumerable horrid crimes; but how many more would disgrace human nature, and injure society, were they not prevented by this silent monitor! Imagine that for one day the Creator were to forbid its exercise, and leave mankind free from its restraints. This world would become an Aceldama—a field of blood. It is this which, un- observed, works in the human mind, urging to the discharge of known duty, and preventing known evil :—which teaches future circumspection, by chas- tising for past offences :—which points out the line of equity, and withholds from acts of injustice :— which forbids the sinner to find repose but in the en- joyment of the supreme good :—and which either admi- nisters satisfaction’ on a recurrence to what has been done pleasing in the sight of God, or inflicts punish - ment for known delinquency. Its operations are at once of unutterable moment to its possessor— to those with whom we are more immediately con- nected in the affairs of life—and to society at large. iy In this brief description of the faculties or powers of the human mind, I have not so much followed the order dictated by metaphysical propriety, as that INTELLECTUAL BEINGS. 293 eee or THE PASSIONS. ~~~ view of the subject which obtains in common life, Dr. Reid observes, that “the powers of the human mind are so many, so various, and so connected and complicated in most of its operations, that there never has been any division of them proposed which is not liable to considerable objections.” He then proposes to consider them under a two-fold division ; that is, the powers of the UNDERSTANDING, and those of the winx. ‘Under the witt,” says he, ““we comprehend our active powers, and all that Jead to action, or influence the mind to act; such as appetites, passions, affections. The unprEr- STANDING comprehends our contemplative powers, by which we perceive objects ; by which we conceive or remember them; by which we analyse or com- pound them; and by which we judge and reason concerning them.” 3 THE PASSIONS. I shall now proceed ¢o state the nature of the PASSIONS.—By the Passions we mean _ those effects which follow from the mind’s being agitated by any cause, either external or internal. If, for instance, an. object present itself, which appears to us suitable to promote our happiness, the mind is affected by it, and feels a DxEsiReE to obtain it: or if an object is exhibited, which is of an opposite nature, deformed and unsuitable, the mind is equally affected, and it feels AVERSION: now this desire and aversion. are passions or affections of the mind. As 294 INTELLECTUAL BEINGS. IMPORTANCE OF THE PASSIONS. the soul is exceedingly sensible and susceptible of im- pression from every thing which affects the organs of the body, and as these objects are very different in their natures and appearances, the passions which are excited by them are many and diversified; but they are of vast moment to man, and may be con- ducive to his happiness and safety, or instrumental in his punishment and misery. The wisdom of God is strikingly manifested in endowing the soul with such properties as the passions. Without them, man would have been but a dull, insipid, and almost inactive being: though he might have possessed a capacity for thought and action, yet he would have had no energy to employ that capacity. Some minds are much more susceptible than others, either from an original difference in their constitution, or in con- sequence of their union with bodies of a less or greater delicacy or vigour of organization. One person will contemplate an object with apathy and indifference, while that same object will throw all the passions of another into the most violent agita- tion, and arouse him to the greatest energy. ‘Lhis constitutional difference is wisely adapted by the Creator to the general good of society. The passions of the human mind are so many and diversified, that metaphysicians have been at a loss to enumerate them, and give them a philosophical classification. As all the faculties of the mind may be reduced to two—speculation, such as the under- standing; and action, as the will—so the passions INTELLECTUAL BEINGS. | 295 LOVE—HATRED. may be arranged under two denominations—LovEe and HATRED. Under the influence of them, we seek to obtain that which seems beneficial, aud to escape from that which appears injurious. Love is that passion or affection of the mind which is excited by such objects as seem to us suitable to our circumstances, or adapted to our happiness: it is as impossible not to love such objects, as it is to love those which appear obnoxious. Under this passion we may place pEsrre, which the. soul feels to obtain what appears good: HOPE, which is felt under the view of realizing the object of love : Joy, which ts elicited by the possession of what is good: sorrow, which is produced by the absence of the object of love: presparr, which follows acon- viction that the object of love cannot be obtained.— All the socrat affections, those which fit man for the pleasures of social life, may be considered as modi- fications of love, or springing from this root. To these belongs that natural affection which parents and children feel towards each other; gratitude for those favours which we receive from each other; pity and compassion towards the distressed ; esteem for the good and the wise; friendship ; public spirit. Besides those passions which arrange themselves under the denomination of /ove, there are others which come under that of HATRED. As under the influence of the former we endeavour to obtain what appears to us adapted to our happiness, so, under the operations of this, we attempt to shun 296 INTELLECTUAL BEINGS. THE PASSIONS CREATED WITH MAN. whatever seems pernicious and injurious. Taken in this general meaning, the term hatred is not used in a’ bad sense, as denoting any malignant. passion, the influence of which would prompt us. to. commit any act injurious to another. ‘This class of passions is as natural to man, and as necessary to his existence, as the former. It is the opposite of that which I have already described. When we feel this passion, it implies a perception of the mind that the object to which it refers would be injurious. As belonging to this, we. may mention disgust, or that modification of hatred which we feel towards any thing that seems to us highly displeasing: antipathy, which we feel towards an object whose nature appears contrary to our prevailing dispositions : fear, which is felt when any thing threatens us with injury. To these might be added several others. They were con-created with the human being, and are essential to that law of self- preservation which was interwoven into his nature. They are excited by such objects only as either are prejudicial to us, or appear to be so; and under their operations we as naturally endeavour to avoid things hurtful to us, as we perceive them .to be of this nature. _ Besides those passions which are essential to man, and whose existence discovers the intelligence of the Creator, there are others so malignant in their nature and operation, that they cannot be resolved into any cause but that which has occasioned our ruin, degra- dation, and disgrace ;—I mean moral evil. It. is the . depravity of our nature, consequent on transgression, INTELLECTUAL BEINGS. | 2907 THE WISDOM OF GOD IN BESTOWING THE PASSIONS. that gives birth to pride, malice, envy, revenge, Jealousy, &c. in whose aspect we perceive the detest- able source whence they spring, and whose operation on the individual and on society is as injurious as their nature is abominable. In order to see the wisdom of God in bestowing these passions upon the human being, imagine first their ABSENCE, and then. contemplate the effects resulting from their PRESENCE and influence. Let us suppose, for a moment, that any human being were destitute of these affections, either by a radical defect in his original constitution, or was bereft of them by some singular calamity ;—and he would instantly lose almost every thing which rendered him interesting and important. He would be a mere cipher, and as much a stranger to happiness, as he would be unfit for energy in action. He might be capable of contemplating a lovely object, but it would be with cold apathy and total indifference ;—he would feel no warm and glowing emotions towards it, and consequently he would use no vigorous exertions to make it his own. Destitute of Jove, he would be a stranger to the finest feelings with which a rational being is acquainted: destitute of hope, he would know nothing of that pleasure which arises from the anticipation of a future good, to which we are so highly indebted in a world of sorrow and of woe: destitute of friendship and of public spirit, he would - be an isolated and useless individual, who would be as indifferent respecting others, as they would be 298 INTELLECTUAL BEINGS. THE BENEFICIAL INFLUENCE OF THE PASSIONS. regardless of him: destitute of desire, he would be incapable of that enterprize which is essential to a great action, in évery capacity or situation. I say, suppose man destitute of these and the other passions which I have mentioned, and you behold a mere reasoning, thinking statue, as much a stranger to happiness in himself, as he would be incapable of the duties of social life. But this supposition is chimerical. The affections are always associated with reason. ‘This alliance is a law of our nature which knows of no exception. They are not indeed always equally energetic and refined, but in a less or vreater degree they are enjoyed by all. The effects resulting from the influence of the passions on the character and actions of man, are most striking and important. Sometimes, indeed, they have led captive his reason, and precipitated him into crimes shocking to humanity and disgrace- ful to man. But when strong affections have been under the direction of an enlightened understanding and a correct judgment, men have achieved won- ders; and we hardly know which to admire most, the wisdom and bevevolence of their schemes, or the energy and perseverance with which they have executed them. All have heard, or read, of the sur- prising energies which some persons have discovered, and the hardships they have endured, in order to obtain the object of their affection. Hope of future good is the main-spring which puts all in motion in this lower world. ‘That passion which we call INTELLECTUAL BEINGS. 299 CO RS A RT ER UTNE ETT RELATION WHICH THE PASSIONS BEAR TO THE CORPOREAL SENSES, patriotism, or the love of our country, has enabled men to forsake their homes, their friends, and their dearest comforts, to risk the greatest sufferings,—nay, their lives also, for the sake of promoting its good. History furnishes innumerable facts illustrative of the influence of the passions over human actions, and their importance to man, considered as a social being, Happy world, had it never defiled these essential principles of the nature of man, nor given them a direction contrary to his reason, to the felicity of his species, and the will of his Creator ! THE RELATION OF THE POWERS AND PASSIONS OF THE. MIND TO THE CORPOREAL SENSES. The organic structure of the five senses with which we are endowed, has been already described. Seeing, hearing, smelling, tasting, and feeling, have an obvious relation to some further design. Their respective nerves meet in a common point in the brain, or sensorium, where, being united to the mind in some manner, to us inexplicable, they convey to it the ideas or images of external objects. It is not my province to enter into the controversy, whether the soul obtain all its ideas through the medium of the five senses, or whether it might have obtained any ideas without them. This is sufficiently evident, that we are not conscious of possessing any other ideas, or any knowledge, except what we obtain by 300 INTELLECTUAL BEINGS. KNOWLEDGE OBTAINED THROUGH THE SENSES, oe them. There can be no doubt that all the senses are equally well adapted to convey to the mind ideas of the objects to which they relate; but in the organization of the eye, we perceive the most evident mechanical structure to convey the pictures of external bodies to the brain. It admits of demon- stration, that the form and colour and position of the objects which we look at are distinctly delineated on the retina; and it is equally certain that what is called the retina, is composed of minute branches of the optic. nerve spread over the back chamber of the eye, and that the nerve from which they branch, goes immediately to the sensorium. Now what can be the final cause of this singular arrangement, if it is not to aid the perceptions of the mind? As mind is that which alone possesses intelligence, which can think, and reason, and judge what is proper to be done, it is necessary that the body should be under its influence and direction ;—and as the nature of its actions must be determined by external circumstances, it is of essential importance that the soul should be made acquainted with them, — in order to shun that which is obnoxious, and to pursue what is beneficial. The senses are granted to meet this necessity, and they form the medium of connexion between the external object and_ the inter- nal perceptions of the mind.—~It is through them that the understanding obtains all its stores of knowledge, and all its materials for reflection and judgment ; by which the volitions of the will are INTELLECTUAL BEINGS. Sok HOW THE PASSIONS ARE AFFECTED BY THE SENSES. determined, and the passions of love or hatred, or their respective modifications, are excited. Not only is the nature of our actions determined by this means, but also the degree of energy which we throw into them. Objects or circumstances possess diffe- rent degrees of importance, in proportion to which, in general, they impress the senses, and consequently produce a correspondent sensation on the mind, and all its powers and affections. The strength of the impression which a given object produces on various | characters, though viewed in the same point of light, is very different. For instance—the same landscape contemplated by two persons, will produce no_sin- sular emotions in the one, while it fills the soul of the other with inexpressible delight. This may be owing, as well to a difference in the degree of deli- cacy in the organization of the eye, as to a different conformation of the mind—probably it is chiefly owing to the latter. This relationship will appear still, more evident, if we consider, that it is by means of the corporeal senses that we either endure sufferings, or enjoy pleasure: for the same organic medium may be sub- servient to both. By the eye, the indescribable beauties of nature afford to the mind a correspondent delight—or disgusting objects produce horror and dread. By the ear, harmonious sounds are propa- pagated to the soul, and produce that pleasurable elevation to which few, if any, are strangers, who have ever listened to vocal or instrumental music ; 302 INTELLECTUAL BEINGS. THE CONSEQUENCES OF THE LOSS OF THE ORGANS OF SENSATION. and by the same organ, sounds so discordant may be communicated, as to fill us with unutterable pain and anguish. The organs of taste and smELt are so delicate, that the one affords remarkable pleasure by being sensible to the fine efuvia which are constantly emitted from odoriferous and balsamic substances, while the other enjoys the essential properties which are exposed to the nerves of the tongue and palate during the mastication of food. The Author of N ature has so abundantly enriched all the substances destined for nourishment with pleasurable qualities, that those in which we discover no such qualities we reject as per- nicious. Every one knows that the same senses may be the medium of as much pain. And what are these pleasures and pains, but internal perceptions and feelings communicated by the senses? I do not deny that the body derives a degree of pleasure or pain by these means; but the most powerful perceptions are those which are mental. If only one of these avenues to the mind is closed, what an extensive range of ideas is precluded! Were they all to be rendered useless, the human being would lose at once all his enjoyments and_ his importance. —Surely, the latter. This preserving care, which Divine Providence extends to all-nature, cannot be sufficiently admired. It reaches as well to the original faculties with which God endowed different beings, as to the laws by which they are governed. Every department of nature was GOVERNMENT OF NATURE. 333 SSS CARE OF GOD OVER HIS CREATURES. en rn a eT NED ES A A RS at the first endowed with qualities or powers peculiar to itself, and suited to its office in the general economy. These being necessary in the original arrangement of things, and suitable to the relation which they bore to each other, and that arrangement being intended to be perpetuated to the end of the world, they are as necessary at every future period as at the first; and hence their preservation and continuance appear of indispensable moment. Any essential change in the principles of nature would render an equal change requisite in its relative connexions ; a change in these would render other changes necessary ; so that any important departure from first principles would render it necessary to form an entire new order of things. A preserving care has therefore been extended by the Almighty Creator over universal nature, every instant of time since its first formation. Hence no ori- ginal quality, however small, has been lost; no power of action has become extinct. All nature now bears the most perfect resemblance to what it was when first formed. Every quality of inorganic matter, every property contained in vegetables, every faculty pos- sessed by animals, remains the same, and operates in a similar manner when placed in like circumstances." * The earth, indeed, was cursed for the crimes of our first parents ; and, consequently, in many places it is barren ; in others which are fertile, it may have lost much of its luxuriance ; and the natural powers of animals have probably been much impaired ; yet these powers remain, and essential principles are perpetuated, if” 304 GOVERNMENT OF NATURE.

All their original powers of action and of locomotion are per- petuated with the different orders of beings which possess them. God endowed their several muscles with what we call a muscular power, or a capacity of contraction and relaxation, which is essential to action and locomotion. In brute animals this power is under the direction of instinct; in man, who is a free agent, itis subject to reason ; in both cases, this faculty is so preserved in being by the Creator, as to be subject to instinct in the one, and in the other.to reason, without any interference with man’s free agency. For, with regard to rational and accountable beings, an ability to act is so preserved to the creature by the Creator, as to allow the creature to use it either in the cause of virtue or of vice, AS IT WILL, without the Creator’s being at all responsible for the crimes which it may choose to commit. This fact duly regarded, and pursued in moral disquisitions, will enable us to solve many difficulties ; and without an attention to it, we shall be greatly embarrassed in a thousand instances. Hitherto we have considered Nature as merely passive,—as ‘‘ clay in the hand of the potter.” But we see all nature in motion; nothing is absolutely at rest. Activity pervades the whole system, animate and inanimate, organic and inorganic. Shall we consider its motions as the uncertain vagaries of chance’ or, shall we regard them as in exact unison with some established laws? Certainly’ not the GOVERNMENT OF NATURE. 335 THE DEVISION OF THE SUBJECT. former. For we discover as much uniformity and regularity in all the motions of matter, as well in the heavenly bodies as among those which more imme- diately surround us, as we do in the forms of organized beings. If we suppose that the one is the effect of chance, we may with equal propriety suppose that the other is: but, as we see the most perfect regularity and uniformity obtaining in both, in millions of in- stances every hour, we must first abandon our reason before we can admit that either the one or the other takes place by chance. ‘The same mode of reasoning which obliges us to reject this supposition as untenable and absurd, forces us: to embrace the other as a rational fact, which is illustrated by innumerable instances in every department of nature. Let us, then, proceed. to contemplate the laws of nature, with a design to develop that inscrutable wisdom which gave them being. Here let it be observed, that there are certain laws which are common to all material existences, which I shall first notice ; and, secondly, consider such as are peculiar to some bodies in distinction from others. First. There are certain laws which are com- mon to all material existences, which I shall briefly describe.” * The Author has endeavoured to take a popular view of the laws of nature, being aware that these laws, as laid down by the great NEwTon, would be too abstruse for common readers. He has also been obliged to refer to some facts already considered, in order to illustrate this part of his subject. 336 GOVERNMENT OF NATURE. THE IMPORTANCE OF THE LAW OF ATTRACTION. THE ATTRACTION OF COHESION. | GPLIL IL OR By the attraction of cohesion I mean, that law of nature by which the insensible particles of bodies are — united into sensible masses. Sir Isaac Newron was the first who discovered this law. Whether it extend to the particles which constitute the fluids which we call air, electricity, and light, it is impos- sible to say; probably it does. For however minute their particles may be, it is likely that they are compounded of still smaller ones. Whatever be the fact with respect to insensible particles, it is certain that this law extends to those of which we are con- scious; and were there no such law in nature, no masses of matter, either large or small, could exist. For, as the original particles of matter, in this case, would have no disposition to unite, they would have remained for ever apart, and the vast globes which constitute this universe, could have had no existence as such. When God created the first principles of matter he gave being to this law. Those atoms attracting each other, and adhering by virtue of that attraction, first smaller, and then larger bodies were formed, ’till worlds, and suns, and stars, appeared in those orbits in which God had destined them to move. and shine to his glory. | This law binds together in the same mass not only bodies of the same, but also of different essential GOVERNMENT OF NATURE. | 337 SS THE CONSEQUENCES OF SUSPENDING THIS LAW. principles. If we examine the bodies which come under our observation on the surface of this globe, it will be difficult to discover any, all of whose ingre- dients are of the same essential properties. Stones, metals, and woods, for instance, how variously com- pound are they! Yet this law acts on these dissimilar principles, and forms results of essential importance to this order of things. What an astonishing variety of materials are brought together in order to form a plant or an animal! But, however wisely their constituted particles might have been arranged in their diversified organizations, if there had been no uniting principle to connect their various parts, instant dissolution must have taken place, and these beautiful forms could have no longer existed. To see the importance of this law of nature, and the wisdom of God in contriving it, we have but to suppose its suspension, or its annihilation, and in- quire for the consequences which would immediately follow.—The beautiful frame of nature would be disorganized ; every fair form would crumble into air, and blend its materials with those of rocks and mountains. Sun, moon, and. stars would cease to shine and adorn the heavens. The whole creation would become a universal blank. 338 © GOVERNMENT OF NATURE. CERTAINTY OF THE, LAW OF GRAVITATION. oo THE LAW OF GRAVITATION. PLIL LO GL There is no material body in the universe but what possesses weight, and hence tends, when unin- terrupted, to some certain point:—this is called by philosophers Gravitation. To dwell on the laws which certain bodies observe in gravitating towards that given point, would be foreign from my object. The fact is the object of reflection. There is no one common point in the universe, with which we are acquainted, to which all. bodies tend. With respect to the solar system, of which our earth is a part, each planet has its own fixed point, to which all the bodies gravitate which belong to it; this point, if we may form an opinion of others from a knowledge of our own, is its centre; and all the planets regard the sun as the centre, to which they gravitate. We may therefore contemplate this law either on a'large scale, as it is illustrated in the solar system; or on a smaller, as explained by the various phenomena of our own planet. Nothing is more obvious to us than that all substances on this globe tend to a certain point.— | When we suspend a stone in the air, and let it go, — though we impress no force whatever upon it, we see that it instantly falls to the ground; it does the same all over the surface of the earth. il wt sats en r SRS, eT ty ee q ws ar ver dow pi wn jseanscidaa ison lors A pkr vhegbabr sot panne: he: ; : - ale Pa Sage Henle PAN Henle — mss Re S| > + cary Oey!

Tr there is a God, as all that has been advanced tends most satisfactorily to demonstrate, it follows, that he has a right to exercise over his creature man, an absolute authority; and that so far as he is pleased to make known his will, it is the unques- tionable duty of the rational and intelligent being to submit and to obey. And ‘‘the moral govern- ment of a society of intellectual beings, implies and consists in an application to their understandings in directing the intelligent will, and in enforcing the direction by the declaration made*.” A moral government supposes a moral governor, and must have a relation to moral agents, or such as are possessed of understanding and will; and the wisdom of it consists in the governor’s so adapting his laws to the capacities of the moral agent, as to effect * President Edwards. 364 MORAL GOVERNMENT OF GOD. MAN’S SUPERIORITY AS AN INTELLIGENT BEING. the purposes of his will, consistently with free agency, and the general principles on which the moral agent is constituted. In order to be more distinct in treating this subject, let us consider man as a moral agent :—show that his Creator has granted him a law which is sufficient to direct him in all his actions for which he is responsible ;—and develop the motives which it contains, and which are the best con- ceivable to excite to obedience, and to deter from crime. MAN A MORAL AGENT. All animals are endowed with powers of action. Of all others, those with which man is blessed, are the most noble and perfect. His form and appear- ance indicate his vast superiority above all the other animals of this lower world, and his intellectual endowments infer a destiny peculiar to himself. But while his animal constitution obviously fits him for action, it is his being endowed with rational powers which makes him accountable for what he does, and which renders him capable of performing actions morally good or morally bad—virtuous or vitious. When we speak of the morality of an action indeed, we suppose a law existing which is the criterion of right and wrong, to which if our actions agree, tied are said to be virtuous, or morally good; and if they are short of its demands, MORAL GOVERNMENT OF GOD. 365 MAN POSSESSES THE QUALIFICATIONS OF A MORAL AGENT, or contrary to its injunctions, they are vitious, or morally bad. This supposes also, that the moral agent 1s possessed of an understanding which enables him to comprehend the rule of duty—with a capacity of judging of the propriety and impropriety of his actions—and with a freedom of will and a power to do that which he chooses.” Man is endowed with these powers; and were he deprived of any of them, he could not with propriety be denominated a moral agent, neither could he be responsible for his actions. Man, as a moral agent, is possessed of an UNDER- STANDING, which enables him to comprehend the rule of duty. When we speak of the actions of men with respect to the laws which are enacted by mere political governments, we call them lawful or unlawful ; but when we speak of human actions with reference to the laws of God, we call them moral or immoral ;—virtuous or vitious ;—which implies that the law is understood. For were man destitute of the powers of perception or understanding, his actions could no more be regarded as virtuous or vitious—morally good or bad, than those of an idiot or a brute. Man, however, possesses this essential pre-requisite of moral agency to an extent sufficient to enable him to comprehend the laws of > The powers of the human mind which are here mentioned, have been already described; they are now regarded with an especial relation to the subject in hand, 366 MORAL GOVERNMENT OF GOD. ee —*—*—=q&q&z—E—~—~—~—~—~0E@~@&@q~—~C—*X<*~—EaaSSSSSS=== a ee SSS MAN FORMS AN ESTIMATE OF HIS ACTIONS. his moral Governor so far as they relate to the duties which he owes to God, to himself, or to his neigh- bour, and consequently, to an extent sufficient to render him accountable for his actions. It is true that the power of perception in the human mind is much impaired by sin, and that the understanding of man was very different before the apostasy of our first parents, from what it is now. Yet this difference of power of perception is remedied by the grant of a revealed law to man as a fallen creature, which he did not enjoy in his Paradisic state. While he retained the image of God, and continued in a state of perfection, he had nothing more to guide him than the law which was written on his heart, and which he perfectly understood; this law, which was obscured by the fall, nay, nearly lost, is restored by the revelation of a law which for substance is the same, which God has put into our hands, and which we have a capacity to comprehend so far as it relates to moral actions. This is so evident, that no man pleads an excuse for his crimes on the ground of not being able to comprehend the laws which forbid them. In this sense, ‘ God enlightens every man that cometh into the world.” Man has a capacity of supe1NnG of the propriety and impropriety of his actions; this is another quality of moral agency. It would have been of little service to man to have been endowed with a capacity to perceive the import of a law considered in its ideas and words, if he had not possessed an MORAL GOVERNMENT OF GOD. 367 MAN POSSESSES FREE-WILL. ability to reason on the data with which the law furnished him, and to judge of the consequences of obedience and disobedience. He must not only be able to understand the import of the criterion of moral rectitude—but be able to judge whether his actions correspond with it or not. Every rational being possesses this faculty; he can “ weigh him- self in the balance” of the sanctuary, and with facility and accuracy discover when “he is wanting.” No man injures himself or his neighbour, or seeks to promote the welfare of both, “ but his conscience is the meanwhile either accusing or else excusing ;” declaring his guilt, or felicitating him with conscious rectitude. FREEDOM OF WILL, anda power to do that which he chooses, is the third qualification of a moral agent.—A_ restraint laid’ on the will, or necessity put on man to do or not to do, to choose or to refuse that which is contrary to his wishes, is to destroy man’s accountability; for how can he be accountable for that which he is obliged to do or not do contrary to his volitions?—It destroys also all ideas of moral agency ;—for what virtue or vice can there be in an action in which we are not voluntary? Hence man was created a free agent, with an ability to stand, but free to fall; and his apostasy was voluntary. Whatever is depraved in the human soul, is owing to his own voluntary disobedience. But though sin has bereft man of his purity, and brought dreadful darkness over his 368 MORAL GOVERNMENT OF GOD. ———SSee———eeEEEESSS———— ee - MAN HAS A POWER TO DO AS HE WILL. understanding, we are still to consider him a free agent; that is, at liberty to act according to his volitions. Were it not so, then it would follow that he could not be either punishable for his crimes, or rewardable for his virtues; for neither the one nor the other would be his own, but imputable to the agent under the influence of whom he acted. It is equally certain that man has power to do what hé wills to do, as it respects moral good and evil. This is generally granted; and to deny it, would be to destroy all ideas of free agency; and to punish man for what he did, or did not, when he had not power to do otherwise, though he willed it, would be absurd and unjust. And the manner also in which the divine influence determines the actions of rational beings, and assists in performing them, is in perfeet consistency with free agency. ‘“ It makes them willing in the day of its power,” and yet does no violence to free agency. It does this by illuminating the understanding to perceive the excellency of what is morally good, and the enormity of what is morally bad, when a desire to obtain the one, and to shun the other necessarily follows, which determines the volition, and the volition determines the action. Thus “God works in his servants both to will and to do of his good pleasure ;” yet man is a free agent.’ * See this subject treat more largely in the Third Essay, Section Third. ” —— MORAL GOVERNMENT OF GOD. 369 THE LAW GIVEN IN PARADISE, AND AT MOUNT SINAT, LL THE LAW UNDER WHICH MAN IS PLACED. LEL EP LPLF Haying proved that man is a moral agent, by showing that he possesses all the qualifications which are necessary to constitute him such—let us show further, that his MORAL GOVERNOR HAS GRANTED HIM A Law which is sufficient to direct him in all those actions which are required of him in his pro- bationary state, and for which he is responsible. As the duties of accountable beings depend on the pleasure of the supreme authority, it is of essential importance that his will should be made known in such a manner as that those whom it is intended to direct might be able to comprehend it. This was granted to man in Paradise by immediate communications from the Deity ; and he understood accurately the moral system under which he was placed. By the disobedience of our first parents, this knowledge was either lost, or their intellectual powers were so beclouded, as to render a fresh revelation of the same moral code essentially necessary ;— this was most graciously afiorded by the instrumentality of Moses on Mount Sinai. A great part of that revelation indeed related to sacrifices, and. to ceremonial w orship, which were typical of a future dispensation; and, consequently, were but temporary in their obligation. Yet, a MORAL SYSTEM was at the same time communicated, which, BB 370 MORAL GOVERNMENT OF GOD. MAN’S DUTIES AS A MORAL AGENT. for substance, was no doubt the same as had been given to man in Paradise, and which is still binding on all men in every country, under all possible circum- stances, and at every age of the world. This code is contained in the decalogue, and is explained by prophets, evangelists, apostles, and Christ himself, ‘‘ who came not to destroy, but to fulfil the law.” Man, as a moral agent, owes certain duties to his Creator, to his neighbour, and to himself. The moral code which is contained in the Sacred Scrip- tures, affords direction in all these cases ; and though a great variety of duties is due in these different relations, yet the Scriptures are singularly replete with direction ;—and not a case can occur, but a law is enacted by the supreme authority which specifies what is the duty of the rational being; or if a law is not to be found which prescribes the duty in express words, we can be at no loss to discover a general principle from which it may be clearly inferred. It is worthy of remark also, that every law, and every general principle which infers a law, are in the most perfect unison with the generally acknowledged principles of equity and sound reason; so that in rendering obedience to the laws of God, we do in fact but obey the dictates. of reason, and conform to the principles of justice. The object of God in establishing the moral government of which I speak is, to advance his own honour, by securing the obedience, and effecting the happiness of mankind. And the more minutely we Eee ee MORAL GOVERNMENT OF GOD, = 371 THE LAW OF MORAL AGENTS CONTAINED IN THE SCRIPTURES. nee examine the law which God has prescribed to them for the accomplishing of this end and its subordinate ends, the more of its suitableness, and the wisdom of its adaptation we shall discover.—It may not be improper to be somewhat more particular. Appealing to the sacred volume which contains a development of this economy, we are. struck with the copiousness of its laws, while we must admire the brevity and perspicuity with which they are delivered. Had they been compressed into a narrower compass than they are, they must have been obscure ; had they been more enlarged, the book which contained them would have been too voluminous for the greater part of mankind to read and to remember. ‘The Scriptures of the Old and New Testament contain a revelation of all necessary doctrines, a great diversity of predictions, and many descriptions of that ceremonial worship which was but temporary and typical; so that if we were to make a selection of what relates to the crimes we are to shun, and to the duties we have to perform, it would be found that the selection would form but a very small volume; yet in this small book would be discovered all the laws which are wanted for the government of a world, however ignorant, unjust, and degenerate its inhabitants may be. God has the first claim on our services; and the Scriptures are replete with laws and statutes for the direction of ovr conduct with reference to himself. They forbid idolatry, swearing by his name, blas- BBQ 372 MORAL GOVERNMENT OF GOD. “scenic miata nei DUTIES WE OWE TO GOD—OURSELVES. phemy, and whatever is offensive to him :—while they prescribe, in the most peremptory language, the worship which he requires—prayer and _ praise, whether it respects the inward state of the mind, or the manner of performing the external duty ; both in private and in public. How plain and comprehensive are such laws as these: — “ Thou shalt love the Lord thy God with all thy heart:”— “God 1s a Spirit, and they who worship him, must worship him in spirit and in truth :’—“ Pray without ceasing =i — “ Sing with melody in your hearts to the Lord :"— “ Thou shalt worship no other God :”—“ Keep your- selves from idols :’—‘‘ Thou shalt not take the name of the Lord thy God in vain :—“ Remember the Sab- bath day to keep it holy.” | Next to God, our own personal concerns demand our attention. While religion, prohibits, and indeed most forcibly condemns mere selfishness, yet it by no means forbids that we should attend to that which is adapted to promote our own happiness; nay, it requires that we should with the most persevering application. It enjoins “‘ that we should seek first the kingdom of God and his righteousness’ —“ Work out our own salvation with fear and trembling” —“ Keep our hearts with all diligence’—“ Yield ourselves to God’—“ Deny ourselves”—“ Crucify the flesh with the affections and lusts’”—‘* Examine ourselves whe- ther we be in the faith”—“ Watch and pray that we enter not into temptation”’—‘“ Repent and believe the Gospel” —*‘ Search the Scriptures” —“ Lay aside every MORAL GOVERNMENT OF GOD. 373 DUTIES WE OWE TO OUR NEIGHBOURS, weight, and the sin which doth most easily beset us, and run with patience the race set before us’—‘“‘ And that we should come to the throne of grace to obtain mercy, and find grace to help in time of need.” Our neighbours also are to share our attention. ‘“ Good will to men” is among the first principles of this sacred code. It teaches us to regard all men as brethren, and requires that we should not only do them no injury, but endeavour to promote their welfare. It is calculated to unite in one affec- tionate family the whole human race; and were it in full operation among mankind, no evil passion would ever be indulged or allowed to appear; injustice, cruelty, and war, would for ever cease ; and peace and love would establish a universal empire in the world. ‘These assertions may be fully justified by a few quotations from the many which the oracles of God contain on these subjects :— “‘ Whatsoever ye would that men should do unto you, do ye even so to them’—‘“‘ Thou shalt love thy neighbour as thyself’—‘“ Do good unto all men”—‘‘ As much as in you lies, live peaceably with all men”—‘ Bear ye one another's burdens’— “ Avenge not yourselves’—“ Put off all these, wrath, malice, anger, &c.”-—“ ‘Thou shalt not kill”— ‘« If thine enemy hunger, feed him, &c.” _ This code of morals is not satisfied with giving general laws; it descends to all the different rela- tions of life. Man is a social being; much of his happiness is derived from his relation to others of his own species; and the Scriptures are explicit in 374 MORAL GOVERNMENT OF GOD. RECIPROCAL DUTIES. < ‘ x v = enjoining the various duties which each owes the other in this vast society. To husbands and wives it says— ‘“‘ Husbands, love your wives, and be not bitter against them.”—‘“* Wives, obey your husbands in all things :” —to parents and children it says—“ Parents, train up your children in the nurture and admonition of the Lord.” —“ Children, obey your ‘sehiaite for this is the first commandment with promise :”’—to kings and subjects it says—‘ It is an abomination to kings to commit wickedness.” — ‘‘ Honour the king.” —To masters and servants it says—‘‘ Masters, give your servants that which is right.”"—‘* Servants, obey in all things them that are your masters according to the flesh.”—It says to the rich—‘“ Be bountiful,’—and to the poor—‘ Be content with such things as ye have.” To all it says— Let your light so shine before men, that others seeing your good works, may glorify your Father who is in heaven.” To see the wisdom of that system of ethics which is contained in the oracles of God, we have but to imagine that all men were toembrace it, and to conform in every thing to its principles, when, it is sufficiently obvious, all men would be happy, and the glory of the supreme Governor of the world must be secured | —which are the important objects it proposes ;—its adaptation to these ends is, in fact, its wisdom. We shall now proceed to the third object proposed, which is, TO DEVELOP THE MOTIVES WHICH THIS LAW CONTAINS, AND WHICH ARE THE BEST CON- CEIVABLE TO EXCITE TO OBEDIENCE, AND DETER FROM CRIME. ee MORAL GOVERNMENT OF GOD. 375 LAWS ENFORCED BY CERTAIN SANCTIONS. PUNISHMENTS CONSIDERED AS MOTIVES TO OBEDIENCE. OL LIPIL ES A law without any motive to stimulate to obedi- ence would be nugatory ; to enact such a law among beings who are radically indisposed to obey it, would argue the greatest folly in the legislator ; for he could not expect any thing rationally, but that his subjects, if subjects they’ might be called, would insult his authority, and trample on his laws with supreme contempt. Hence all legislators have decreed the sanction at the same time they have enacted the law ; for it is not the authority of the legislator, nor the rationality of the law, nor its suitableness to their condition, that will, in all cases, secure obedience, where there are counteracting interests of a private nature. The sanction is the great motive to obedi- ence; and the more important the reward or the punishment, the greater is the probability of securing this object. The moral code which God has esta- blished for the observance of mankind, infinitely exceeds, in this, and in all other respects, the laws enacted by mere human authorities. The latter only threaten a punishment in case of disobedience, and proceed on the principle that obedience is its own reward; but the former promises a positive reward to obedience, as well as threatens a certain punishment in case of disobedience ;—and both are so admirably 376: MORAL GOVERNMENT OF GOD. NATURE OF SIN—ALL SINS NOT EQUALLY HEINOUS. adapted to the condition of moral agents, that if they fail to secure obedience and to deter from crime, it is difficult to conceive of any that can. Let us first consider the punishments which God, the supreme authority, has threatened, to prevent crime. — Offences against God are of two descriptions; they are either those of OMIssioN, as when a duty is neg- lected, though it is absolutely enjoined; as, for in- stance, the law says--“‘ Remember the sabbath day, to keep it holy”—but if it is not kept holy, the law is broken by the omission :—or they aré crimes of com- MISSION ; when the law forbids certain actions, as, for example, when it enacts—‘‘ Thou shalt do no murder’—** Thou shalt not steal”—it is obvious, that if we commit murder, or take away another’s property, we break the law. ‘This latter description of offences are called in the Scriptures, transgressions, and the former disobedience; against each of which God has threatened a just punishment ; for in crimes of both descriptions there is an equal disregard to the divine authority, and both are punishable for the same reason. It will not be maintained that all crimes are equally heinous, or that the same degree of moral evil is comprehended in every sin: and hence, we are not to imagine that the Judge of all the earth, who must do right, either threatens or inflicts an’ equal degree of punishment in all cases of offence. Every sin shall receive a susT recompence of reward: Let us now consider the punishment which God threatens to inflict on the sinner, as a MOTIVE to obedience. a ee ee eee MORAL GOVERNMENT OF GOD, 377 MANY SINS PUNISHED IN THIS LIFE. The punishments which the moral governor threa- tens to inflict on sinners relate either to the present, or to the future state of their existence, or to both.—Some of these punishments are threatened to be inflicted in this world. ‘There are many crimes with which God has so connected their punishment, that when the one is done, the other takes place with absolute certainty if discovered ;—as reproach, loss of character, the abhorrence of mankind when the crimes of dis- honesty, adultery, and various others are committed. With others, bodily disease is connected. Indolence, God often punishes with poverty and want. Tem- poral punishments are not always so self-evident as in the instances 1 have mentioned—they are often mental. Man has a soul as well asa body, which is equally susceptible of punishment, and which the chastise- ments of a spiritual agency can reach with as absolute a certainty. ‘A wounded spirit who can bear?” How wretched is that man’s state whom God. gives up to judicial blindness and hardness of heart! When the arrows of the Almighty penetrate the conscience, and guilt, and remorse,:and fear, begin to torment the soul, the condition of the sinner is truly dreadful. His body, his soul, and. his circumstances, are all within the reach of a sin-avenging God who. is never at. a loss for means by which to effect the pur- poses of his just displeasure. How often does God punish parents, who neglect their duties to. their chil- dren, by their perverse dispositions, their unbecoming behaviour, and their enormous wickedness. The case of 378 MORAL GOVERNMENT OF GOD. SIN PUNISHED IN THE FUTURE STATE. Eli is a remarkable illustration of this truth. | Profli- gate husbands are generally punished with bad wives ; unjust masters, with abandoned servants; and tyran- nical kings, with infamous subjects. Sins have fre- quently a punishment inflicted which bears some obvious relation to the crime which has deserved it. Derangement is sometimes the punishment inflicted for pride of intellect; prodigality is punished by poverty. But to see the full force of this motive, we must extend our views beyond the grave. It is principally ina future state that sin receives its just recompence of reward. A life of sin, and its deserved punishment, are not, in fact, so disproportionate in the present life even as we imagine. Were all men to make a candid confession of the misery which they endure, in conse- quence of rebelling against God, it would tend to substantiate this remark far beyond what is obvious and clear to mankind. We may lay it down as a general principle, that the most guilty are the most unhappy. For as happiness is, generally speaking, in proportion to out holiness, so misery is according to the extent of sin. However, as the present is not the state of retribution, but of probation, it would be un- suitable for the moral governor of the world to display his justice in punishing sin in proportion to its de- merits here; this is reserved for the state on which disembodied spirits enter when their probationary career is closed, when “ every man shall receive for the things done in the body accorpiNe to that he hath done, whether it be good or bad.” ee es MORAL GOVERNMENT OF GOD. 379 A FUTURE STATE—NATURE OF ITS PUNISHMENTS, That such a state exists, is most clearly revealed in the Sacred Scriptures; ‘‘ for life and immortality are brought to light by the gospel.” ‘This was long a matter of doubtful disputation among the heathen philosophers. Though they were exceedingly solici- tous to arrive at certainty on a subject so peculiarly momentous and interesting, yet they continued to vacillate between hope and fear, till God himself determined the question by revealing the fact to the world. To attempt to prove that such a state exists from the pages of the sacred oracles, would be as preposterous as to attempt a demonstration that the sun shines atnoon. ‘Taking it theretore for granted, I shall proceed to describe the punishments which God inflicts on ali who die in a state of impenitence. To ascertain the nature of these, we must appeal to the same authority as that which establishes the fact of human existence in a future state. The sacred vo- lume describes the nature of those punishments, and asserts their duration. Their nature is tremendous. The Scriptures use figures, and employ language the most striking and impressive conceivable, in order to. describe them. They threaten “ Indignation and wrath, tribulation’ and anguish, to every soul that sinneth;” they assure us that the impenitent soul shall be ‘cast into a lake which burneth with fire and brimstone, where there is weeping, and wailing, and gnashing of teeth.” The offended judge will say to all such :—‘ Depart from me, ye cursed, into everlasting fire prepared for 380 MORAL GOVERNMENT OF GOD. THE NATURE OF FUTURE PUNISHMENTS—ETERNAL. the devil and his angels.” It is called the “ wrath to come.” Such is the language which the Holy Spirit employs in order to discover the awful nature of those punishments, and the unmixed misery which the lost endure! But however strong the language, and awful the figures employed, they fail to give us a complete idea of the condition of the enemies of God in the future state. For what language can express, and what mind conceive the misery, the pain, the anguish that a rational creature endures under the unmixed wrath and displeasure of God? For such a being to be utterly bereft of all enjoyment, and all possibility of enjoyment, and consigned. to agonize under the deepest consciousness of his sins in hopeless despair, in a state of impenetrable gloom and darkness, where nothing but unutterable suf- fering is felt, and the shrieks of millions in the same forlorn condition are heard, is so tremendous as to baffle imagination itself. The same infallible authority which describes the nature of these punishments, asserts their endless duration. The “ fire’ into which the enemies of. Christ “depart,” is called “ everlasting fire’—“‘ these go into everlasting punishment,” where ‘ the smoke of their torment ascendeth up for ever and ever.”— “There their worm dieth not, and the fire is noé quenched”—their darkness is an ‘‘ everlasting dark- ness.” If such expressions do not convey the idea of an ETERNAL duration of suffering, it is difficult to conceive of any that can. ‘The smallest degree Ne eEeeEeyEeeEeeeEeeEeEeEeEeEeEeEeEEEOEeyeEeEeEeEEeEeEeE—ee ee ee MORAL GOVERNMENT OF GOD. = 381 FUTURE PUNISHMENTS INFLICTED ON THE ENTIRE PERSON, eae of pain continued through an eternal duration, would constitute a punishment of dreadful magnitude: what then must be the sum of those sufferings which have been just described, perpetuated to everlasting ages? Nature agonises at the thought; let the sinner repent, and flee from the wrath to come. These punishments will be inflicted on the whole nature of impenitent sinners, which will be so capaci- tated as to be able to endure them. ‘The soul will enter upon them immediately it leaves the body. In the day of the general resurrection their re-union will take place; both will be constituted on immortal principles; and, as they were companions in sin, they shall be identified in the suffering—“ for they shall come forth to the resurrection of damnation.” This punishment will not be that of the endurance of actual pain only; it will be exceedingly aggravated by the recollection of what is lost. The loss of all the bliss of heaven, and all the felicities which arise from the joys of the divine presence, is the greatest that can be sustained or conceived; and_ the knowledge which the damned will have of what they have for ever forfeited, will inexpressibly ageravate their misery. If fear of punishments so clearly denounced against impenitent transgressors tends -to deter them from sin, as it unquestionably does, can we conceive of any punishments more adapted to excite fear, and consequently to prevent sin, than those threatened by the Sovereign of the universe in his holy word? 382 MORAL GOVERNMENT OF GOD. DIFFERENT MINDS INFLUENCED BY DIFFERENT MOTIVES. REWARDS CONSIDERED AS MOTIVES TO OBEDIENCE. COLPE LEO As we have viewed the punishments which the moral governor has threatened in his word to inflict on those who disregard his laws, as a motive to ° obedience ; we shall now contemplate the REwaRDs which he has promised to, or connected with obe- dience in the same light. Among his rational and intelligent creatures in this world, there is a con- siderable diversity of constitution. Some callous minds are insensible, in a great degree, to rewards as motives to action, and nothing will arouse to obedience or deter them from crime, but the exhibition of a severe punishment which will be certainly inflicted in case of sin. However, the persons who are thus constituted are few in comparison with those who possess a more generous conformation of mind, and are influenced more by the hope of reward. ‘To render all without excuse, he to whom we are responsible, has set before us both :—it is rewards considered as motives to obedience which now require to be noticed. It has been often said, that ‘‘ virtue is its own reward ;” and the remark is accurate, if by VIRTUE is meant obedience to the will of God; for a higher authority still-has declared that, “ in the keeping of his commands, there is great reward.” ‘When MORAL GOVERNMENT OF GOD. 383 THE RIGHTEOUS OFTEN REWARDED IN THIS LIFE, the operations of the various powers and passions of the human mind are in unison with the will of the supreme intelligence, and our actions harmonize with his laws, a happiness is enjoyed, which must be possessed in order to be understood. As God in his providence has united punishment with sin even in the present state, so there is also a present reward connected with obedience. This reward is not always visible; for it not unfrequently happens that the most holy and obedient of the servants of God, to human view, are the most afflicted. Poverty and disease may be the companions of a Job, of whom the highest character is recorded, “that he was perfect and upright, and one that feared God, and eschewed evil.” But amidst all these sufferings, there may be Job’s supports and consolations which were evinced by his cheerful resignation, and his devout submission. Enoch was a man eminently devoted to the service of God; it was his supreme delight to obtain his approbation, and to promote his glory; and he ranked amongst the happiest of his species; for to confer on him a signal reward for signal piety, he was exempted from the common debt of nature, and was translated to heaven that he should not see death: and even before his translation, he had this testimony, that he pleased God. A felicity unknown to the wicked, singular in its nature, and extensive in its degree, must have been the companion of so remarkable 384 MORAL GOVERNMENT OF GOD. THE PLEASURES OF A LIFE OF RELIGION. a consciousness. | Holiness and happiness are but cause and effect. _ The present pleasures of a life of religion more than compensate for all the sufferings to which it may expose its possessor, and infinitely exceed all the felicities of mere corporeal gratification. Is there any thing in sensual pleasures that can be compared with communion with God? the enjoyment of the divine favour? a consciousness of pardoned sin? an hum- ble confidence of an interest in the divine favour, or a lively hope of a glorious hereafter? These enjoyments are not peculiar to any particular age or condition in life, or to health or sickness; or to any state of progress in the career of mental culti- vation. No: they are the attendants of those whose hearts are right with God, and whose principles are developed in a strict regard to his law. True religion is associated with pleasures and advantages even in the present life, which nothing else can yield. Riches, fame, or intellectual supe- riority may indeed afford to their possessor a satis- faction correspondent with their own individual nature ; but this is a satisfaction at once low and transient: but the religion of Jesus, while it main- tains all the dignity and grandeur of its divine founder, affords joys which are unspeakable, and hopes full of immortality. ‘“ It has the promise of the life which now is.” “ His ways are ways of pleasantness, and all his paths are peace.”. An MORAL GOVERNMENT OF GOD. 385 FUTURE REWARDS, experimental acquaintance with its doctrines, and a practical regard to its sacred laws, cannot but form a character of real dignity, produce that peace and harmony in the powers and passions of the soul, and yield those consolations, which constitute true happiness. Afflictions, and disappointments, and temptations, will befall the best of men; and the last enemy will take down the earthly house of their tabernacles; but religion, while it supports by its promises, and guides by its counsels, sooths by its operations, and cheers by its smiles. Yet it is in a future state of being where the rewards of obedience are to be principally enjoyed. When I speak of the rewards of obedience, I would not be understood to mean, that human obedience in the present, merits any rewards in a future state. Divine revelation declares salvation to be all of grace, or the free and undeserved favour of God bestowed on mankind, by virtue of the Redeemer’s mediation alone. ‘ There is salvation in none other.” Yet the Scriptures represent it as a reward, because it is to be obtained by the use of the instituted means, and it is promised to all who repent, and believe the gospel. | The nature of future blessedness is often the theme of inspiration. While the fact of future ‘life and immortality is stated with unequivocal certainty, their excellency is unveiled with the cloudless per- spicuity of meridian day, and brought within the sphere of the most limited comprehension ;—or at . uC 386 MORAL GOVERNMENT OF GOD. ——————eeeeeoeeee ee e————————————eeEeESSs—_—.—————— NATURE OF THE HEAVENLY STATE, least, enough of them, to eclipse every rival claim, and to justify the greatest worldly sacrifices which may be required in order to make them our own. Heaven is the immediate residence of God. There are fountains of living waters, and oceans of joy. There is the beatific vision, clear and eternal as the father of lights, with whom is no variableness nor the shadow of a change. ‘There the redeemed “ shall come to Mount Zion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, to the general assembly and church of the first-born which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, and to Jesus the Mediator of the new covenant.” Sin and suffering will be for ever excluded ; a perfection of nature and a completion of bliss shall be enjoyed by all its glorified inhabitants; and they shall walk the golden streets with crowns of glory, and palms in their hands. A perfection of happiness shall be connécted with a sinless condition, with an eternity of joy, and with immortality of being. The inspired writers employ the grandest meta- phors and the most simple representations in order at the same time to instruct the understanding, and to fill the mind with the noblest conceptions of the heavenly state. They describe it as our “ Father's house”—a “‘ rest which remains for the people of God”—“ the marriage supper of the Lamb,” and as a place where there is “no night.” How simple MORAL GOVERNMENT OF GOD. 387 THE HEAVENLY STATE. and easy of comprehension! Again, they describe it as “‘a far more exceeding and eternal weight of glory”—as ‘“‘ that which eye hath not seen, nor ear heard, nor hath entered into the heart of man to conceive’—“‘ an inheritance incorruptible, undefiled, and which fadeth not away’—a “ throne”—a “ king- dom.” How vast, and how far beyond the grasp of the most vigorous imagination ! The employments of the heavenly state are all suited to the powers and dispositions of glorified spirits, and cannot fail to yield an increasing happiness equal to their augmenting capacities. The redeemed are described as having ‘ golden harps in their hands,” and as “ singing the new song of Moses and the Lamb ;” as “ falling down and worshipping him that sits upon the throne;” as “ ascribing to him might and dominion and glory for ever.” The mysteries of redemption, the works of nature, and the operations of Providence, will afford them ever- lasting employment and delight; and though they will throw all their vast energies with unceasing ardour into these researches, no sameness will ever cloy, no exertion will ever fatigue. The divine efful- gence will beam upon their astonished sight for ever ; and every divine perfection will appear with increasing lustre every instant of the eternity of the bliss; yet the creature will never be overpowered, nor complain of being satiated. This is heaven: yet heaven is infinitely more than this. . | cca 388 MORAL GOVERNMENT OF GOD. THESE SANCTIONS THE EEST POSSIBLE. Could the moral governor of the world have connected with his laws, sanctions more solemn? motives more powerful? If the punishments which he has connected with sin, fail to deter from the commission of it—if the rewards which he has pro- mised to obedience, do not allure to holiness in principle and practice—I am at a loss to conceive of any that could. With such motives before us, sin must appear madness, and holiness a reason- able service. The more we scrutinize that system of moral government under which man is placed, the more of the wisdom of its arrangements must be apparent. The sovereign maintains all the dignity of his throne, while he legislates for man; his laws are not the imperious dictates of a capricious tyrant, but the wise counsels of an infinitely intelligent monarch, as replete with goodness as they are vast in dignity. While he consults the imbecility of his subjects, he adapts his laws to their capacities, and controls moral agents by ,moral considerations. Thus he accomplishes the purposes of his heart, without violating tne principles of free agency. Two reflections shall close this part oft our subject. First : How great is the guilt of those who forfeit the rewards promised, and expose themselves to the punishments denounced by the moral government of God, by a disregard to its laws! These laws are ——-r MORAL GOVERNMENT OF GOD, 389 REFLECTIONS, a plain, and are promulgated. without any ambiguity arising from the use of a technical and abstruse phra- seology ; man is endowed by his Creator with capa- cities to comprehend them. And though we observe in different human beings an astonishing variety of intellect, rising from unit to an indefinite height on the scale of moral calculation, yet every accountable being has a capacity equal to a comprehension of the law by which he is to be judged; “The way- faring man, though fool, shall not err therein.”— The motives to obedience arising, on the one hand, from the punishment threatened, and on the other from the reward promised, are so great and so pow- erful, that no man can plead the want of argument sufficient to induce him to desist from transgression, and obey the precept.—Besides, however injurious the fall of man may have been to that faculty of his mind which we call conscience, yet its serious dictates are generally in unison with the essential principles of right, and those laws and institutions which originate in the sovereign will of the supreme governor ; such, for instance, as the sabbath and public worship. The guilt of those especially, to whom God has published his moral code, is aggravated by every imaginable consideration. And being entirely volun- tary in disobedience, none can charge God with an act of injustice when after death he withholds the reward, and inflicts the punishment. A disregard of laws founded in reason, in equity, and in benevolence, supported by sanctions which relate to both the 390 MORAL GOVERNMENT OF GOD. REFLECTIONS. present and the future life, is an aggravation of human guilt, which exceeds the powers of descrip- tion. Secondly : How valuable are the Sacred Scriptures to mankind! If man jis responsible for his actions to his supreme Governor, it is of infinite importance to him that he should be acquainted with the laws which prescribe his duties, and which prohibit crimes. These laws were originally made known to man, and written upon his heart. But when he apostatised, if this law were not entirely obliterated from his mind, and every dictate of right and wrong destroyed, yet it is evident that it was so much so, as to render it necessary that a fresh moral code should be granted ‘to our fallen world,—which was done by a compas- sionate God on Mount Sinai, written by his own finger on the two tables, and afterwards copied by Moses, and transmitted to posterity for its benefit as long as the world should remain. When the Redeemer came and established a new dispensation of divine worship, he admitted all this sacred code, gave it the most ample exposition, and shewed at once his approbation ‘and ‘his delight in it, by fulfilling most perfectly all its precepts ;—“ and he left us an ex- ample that we should follow his steps.” In the spirit and obedience of the incarnate Saviour, the whole law of God was embodied. In his assumption of our nature the law itself became incarnate, and was unfolded in living characters.—How invaluable the book which contains a legible transcript of the will MORAL GOVERNMENT OF GOD. 391 REFLECTIONS, of God, recommended by an example so illustrious! —And who, that is conscious of his responsibility at the bar of the Judge of quick and dead, but must be anxiously desirous of knowing the contents of such a volume !— With the means of knowledge in his hands, who can imagine that his ignorance will excuse his guilt, or plead for the remission of his offences ?- Who in this country is acquitted from a crime which has been proved against him, because he sets up the plea of ignorance of the statutes which have been enacted ? In civil affairs, ignorance is no excuse. And why should we suppose that a government which is perfect, will dispense with a principle that is considered to be indispensable by governments which are imperfect ? To imagine that God is merciful, and that he will therefore pardon, will avail nothing; because it may be maintained on the other hand that he is just, and therefore will punish. Rather let all seek to possess so interesting a volume; and possessing it, diligently study its contents, and abound in every good word and work. This volume is the great luminary of the moral word; and criminal indeed is that man’s conduct, and just his condemnation, who closes his eyes against the light, either by denying its authority, or by neglecting its sacred contents. oe Me o* part Shiro.

No truth is more generally admitted by all who acknowledge the being of a God, than that he foresaw from eternity whatever takes place within the vast range of his universe; and that this prescience extended not to the more prominent events only, but to the most minute also,—and for the same reason—because his understanding is infinite. The vast design must therefore have been laid and fixed; all the details and subordinate parts must have been arranged down to circumstances the most trivial, even to the “ num- bering of our hairs,” and “ the falling of a sparrow.” And let it not be imagined that an arrangement so complete and universal was either unnecessary, or unworthy of God ; for they are events of a subordinate order which generally originate those that are of the greatest importance, and fill the world with asto- nishment. | I am aware that while my principle is generally granted, my inference from it will be disputed. All 396 GOVERNMENT OF EVENTS. _ALL EVENTS CERTAIN. who will admit that a Being of Infinite Intelligence must necessarily foresee every future occurrence, how- ever remote the period at which it may happen, will not allow that the plan was laid, and the event made certain. But, does not a foreknowledge of events necessarily infer their certainty? If they were not certain, but depended on fortuitous circumstances, or chance, how could they have been foreseen? If chance be admitted, then the result is uncertain ; it may issue in this, or it may terminate in that; and which of the two, cannot be known ’till the result determine. Neither is it enough to say that God made this arrangement so far as leading occurrences are concerned, but that those of an inferior order were not taken into the fixed plan. For who shall draw the line of distinction between important and unimportant events? or where is that line to be drawn? Besides, to deny the universality of the arrangement, not only contradicts the principle which I have said is generally admitted, but by a pretence of delicacy to the’ Deity in not troubling him with such little things, they, in fact, cast a reproach upon his perfections. Can it be any more difficult to an Infinite Being to arrange a million events than two? Cannot he with the same facility control the affairs of a world, and those of a family? and those of a uni- verse, as those of a world? In reasoning on such topics, men betray the most melancholy ignorance and folly; and show. that, with all the high sounding compliments which they offer to the Author of their Eee oe - ee ee a GOVERNMENT OF EVENTS. 397 ALL EVENTS UNDER GOD. being, “‘ they think him altogether such an one as themselves.” God, having laid the plan of all his future pro- cedure, superintends its accomplishment. This is Providence. And as the laying of the plan ensures its development in a regular succession of events, so will this development of events at once coincide with the plan, and unfold it to the intellectual universe. How animating to him whose mind is imbued with real piety, to see God every where, and to recognise his superintending hand as well in the events of his own history, as in the rise and fall of kingdoms and empires. This renders the soul tranquil and peaceful amidst the storms, and thunders, and tempests, of the natural and moral world; and enables us to calculate on a benevolent and wise result, under a co-operation of circumstances the most disastrous, and, to human calculations, the most perplexing. In contemplating the events which are. passing before our eyes, or which history presents to our minds, there is a surprising diversity ; but this di- versity is reducible to two orders ; some are MORALLY EVIL; they cannot be the effect of a divine agency, yet they are PERMITTED: others are’ MORALLY Goop; they are worthy of a divine interference: hence we ASCRIBE THEM IMMEDIATELY TO Gop. My object is now to ascertain that Divine Wisdom which is apparent as well in what God permits to transpire, as in what he actually accomplishes, ~ 398 GOVERNMENT OF EVENTS. eee MORAL EVIL NOT TO BE ACCOUNTED FOR, —————eeeeeeeeeEeeeeeEeE—E—E—E—EoE—E—E—E—Eeeeeeeee THE PERMISSION OF EVENTS, SIIP LOL There are many events that take place, which are obviously EvIL when viewed with reference to the criterion of moral excellence; and we cannot connect them with the agency of the Deity without dis- honouring his perfections, and charging him with folly. If God cannot. be the author of them, how shall we account for their existence?, There is a principle of moral evil in the world; that principle is operative ; it exerts a controlling influence over mind; mind exerts an agency productive of events; these events partake of the evil cause by which they were pro- duced : they might be prevented did a superintending Providence choose to interpose a preventing agency. Yet, events morally evil are permiTTED. Were I asked why the Deity allows such events,—events so evil in themselves, and so. obviously contrary to his holy nature and government? reasoning from the fact only, I should reply, I can give no satisfactory answer. But were the inquiry proposed, has he in any way taken an opportunity of making the existence of moral. evil in this world subservient to his own glory? I should not feel it difficult to return some answer which, to myself at least, is satisfactory. Infinite Wisdom has discovered methods by which to glorify the divine perfections from the fact of the existence of sin in the world to such an extent, as GOVERNMENT OF EVENTS. 399 MORAL EVIL OVERRULED TO THE GLORIFYING OF GOD. Sarre ee ee a ee eee aetna eee ea taasnopn ee een could not have been done had sin been prevented ; yet sin remains in all its malignity, and its existence not in any way chargeable upon the Deity. I shall attempt to explain this subject by illustrating a few short propositions. F'irst.—Moral evil has appeared in our world ; but Divine Wisdom is manifest in glorifying those attributes of God, which could never have been dis- played in the world, but for the permission of it. How the pure minds of angelic and human beings, which were created spotless and perfectly innocent, became at first guilty and depraved, is a question at once in- explicable, and irrelevant to my present subject : I have to do with the fact, and not with the origination of the fact. By what mean angels fell, we are not informed ; but divine revelation resolves the existence of sin among the human race into the agency of one of these evil spirits on the minds of the first parents of the human race. They were created in the image of God, which consists in righteousness and true holiness, with strength to stand, but free to fall. As they were placed in a probationary state in Paradise, furnished both with a law of moral obedience, and having sufficient motives of rewards and punishments presented to induce them to maintain their integrity, it was essentially necessary that they should be free agents, and that their free agency should be left to its own operations. Had their Creator exerted any force, excepting to preserve to them the full power of their natural faculties, their free agency would 460 GOVERNMENT OF EVENTS. eee eee SSS ae oem" THE PLAN OF REDEMPTION REVEALED. have been destroyed, and they could no longer have been rewardable for their integrity, or punishable for their disobedience. But how did they act under these circumstances? They voluntarily listened to the voice of the Tempter, transgressed the law of God by eating the forbidden fruit, forfeited their bliss both in possession and in contemplation, became liable to the punishment threatened, and, by their inexcusable and most aggravated crime, incurred the wrath of God, and entailed their guilt and its attendant miseries upon all future generations. Thus at once was his noblest of works marred, and this fair creation filled with confusion and death. Satan, aided by the first of the human race, established an empire opposed to the holy government of God, which should enslave all their descendants. But shall the chief enemy of God triumph over the best of beings, and succeed in his infernal designs, and reign for ever over aruined world? No. An expedient shall be found; a plan shall be unfolded which shall convert this most melancholy of all events into a blessing. ‘The wisdom of God discovers a remedy. A plan, already matured in the counsels of Eternity, under the foreknowledge of the fall of man was ready to be revealed, which should at the same time confound the projects of devils, and restore rebel man from all the evils of the fall to the enjoyment of a bliss infinitely beyond that of an earthly Paradise. This is the plan of Re- demption. | % GOVERNMENT OF EVENTS. | 401 a nT ERE TT eee ek oe eee ee ert REDEMPTION DISPLAYS JUSTICE, MERCY, WISDOM. $$ When man transgressed, sustrice descended to vindicate the honours of the broken law; but mercy accompanied at his right hand: myriads of angelic beings followed in their train. All the powers of darkness stood at a distance to witness the result of so awful a process; in their looks a glimmering of hope sometimes was seen; but the most agonizing fear and dismay prevailed. Justice and mercy hastened to Paradise. At length the criminals appeared at the august tribunal; guilt, shame, remorse, horror, and despair, clothed those features, recently so lovely. To ascertain the fact of their guilt, but one witness was necessary to be called ;—it was conscience. But the criminals were allowed ta plead in mitigation of punishment. Adam said, “ The woman whom thou gavest unto me, she gave me, and I did eat.” The woman said, ‘“ The serpent beguiled me, and I did eat.” But the plea which they set up increased their danger by aggravating their offence. Justice drew his sword to satisfy the law by inflicting the threatened punishment, but mercy arrested the falling blow, and pleaded an opportunity of asserting her claims as well as justice. She pleaded an equal glory, and an equal right to manifest her beneficence in a fallen world. Their claims were opposite. Justice re- quired punishment as that which alone could satisfy the law, and the honours of God’s moral government ; mercy demanded an opportunity of pardoning the offence. How shall their opposite claims be recon- eiled? Divine Wispom arrived, and proclaimed, DD 402 GOVERNMENT OF EVENTS. WISDOM FINDS MEANS FOR MAN’S RECOVERY. ‘ Deliver the criminals from going down into the pit : I have found a ransom.’ The Son of God, “ in the ullness of time, will assume the nature in which the crime has been committed; on his sinless body he. will bear their iniquity, and give mercy an opportunity of pardoning, by offering to justice a satisfaction of obedience and of suffering fully equal to the utmost of his demands.”—The criminals heard it; and hope banished despair from their hearts and their looks, while the pleasures of pardon and _ reconciliation thrilled and vibrated through every vein: devils heard it; and fled like a flash of lightning through the horrid gloom which surrounded them, and with dreadful precipitance hastened back to their infernal abode, loaded with chains of everlasting darkness: angels heard it; and tuned their golden harps, and sang with melody as they never sang before—‘ Glory to God in the highest, peace on earth, and good-will to men.” “ Salvation to our God which sitteth upon the throne, and to the Lamb for ever:” the vast expanse of Heaven heard it; ‘and re-echoed the reviving tidings from pole to pole, and from the river to the ends of the earth—‘ Glory to God in the highest, and good- will to men.” In the plan of salvation by the incarnate Son of God, “ mercy and truth meet together, righteousness and peace embrace each other;” and God appears in the character of ‘‘a just God and a Saviour.” But could justice, mercy, and love have appeared under such illustrious displays in our world, if sin GOVERNMENT OF EVENTS. 403 —aSSeeee———e——eeee————e—e—ee—eeee——qaD—>E>[[[[?[=[Se CALAMITIES MADE BLESSINGS. had not been permitted? Yet this fact does by no means justify the transgression, nor lessen the evil of crime: it only affords an astonishing manifestation of Divine Wisdom in making the worst of all evils, the most tremendous of all events, the means of promoting the glory of God. Srconpiy.—lIndividuals of the bike race are groaning under the effects of moral evil :—divine Wisdom is apparent in rendering them subservient to the good of those who are exercised by them. I shall first consider this subject as illustrated by the facts of the histories of wicked men.—It has not unfrequently been observed, that events unspeakably calamitous have befallen the most profligate of sinners, which have been overruled for their ultimate benefit. Manasseh, the son of Hezekiah, is a striking instance. Being raised to the throne when he was but a boy, he had every opportunity of indulging his wicked passions. He soon appeared one of the worst of human beings, indulged in all the excesses of sen- suality ; and devoting himself to idolatrous practices, he worshipped the sun, the moon, and the stars. He delighted in every kind of cruelty, and made Je- rusalem to flow with innocent blood. In the twenty- second year of his reign, the King of Assyria and Babylon invaded his kingdom, routed his troops, and caught him entangled among thorns, and carried him a prisoner to Babylon. How calamitous these events ! But he then cried unto the Lord, who gave him re- pentance, and pardoned him, and remitted the eternal DD2 404 GOVERNMENT OF EVENTS. EVILS OVERRULED FOR GOOD. punishment due to his sins, though his kingdom suf- fered in a temporal respect for the crimes of its king and his subjects. Another instance is the thief who was crucified. with the Redeemer. He had ranked with the vilest of his species, being chargeable with robbery and sedition. At length the secular arm arrested him, and he was condemned by the civil authority to suffer the death of crucifixion. What a melancholy event of his abandoned life was this! But see how divine wisdom overrules it for his immortal and eternal welfare. He was doomed to suffer death with the Lord of life and glory ; and when nailed to the cross, he began to relent, and earnestly supplicated the mercy of a dying Saviour, saying, ‘‘ Lord, remember me when thou comest into thy kingdom ;” and Jesus said unto him, ‘‘ This day thou shalt be with me in Paradise.” | We have also instances of good men, in whose history great moral evil has been overruled for their essential benefit.’ The case of Jacob and his son Joseph is prominent. A singular concatenation of evils pursued Joseph :—the envy and hatred of his bre- thren ; their selling him as a slave to the Midianitish merchants ; their sellng him again in Egypt; the | infamous falsehoods which his mistress devised against him; the consequent anger of his master, who instantly put him into prison; and the ingratitude of Pharaoh’s butler, who promised to interest himself in his deliverance’ from imprisonment, but forgat him. ae ee ee, GOVERNMENT OF EVENTS. » 405 JACOB—JOSEPH-~DANIEL. Yet all these evils, which were permitted of Provi- dence, and designed by those who were agents. in inflicting them, to injure Joseph, were making way for his aggrandizement.. His enemies meant them for evil, but God intended them for good,—even Joseph’s personal exaltation over Egypt. When the famine in Canaan obliged his father Jacob to send his sons into Egypt to buy corn, they came to Joseph. He imme- diately recognized the features of his brethren, though he concealed the fact, and detained his brother Simeon as an hostage, ‘till the rest went for Benjamin. When they came and told the circumstance to Jacob, he was overwhelmed with sorrow, and ina paroxysm of grief exclaimed, ‘‘ Joseph‘ is not, and Simeon is not, and will ye take Benjamin also? All these things are against me!” But the event proved that he was mistaken. An unerring Providence rendered all these afflictive dispensations of incalculable ad- vantage to both these eminent men. The history of Daniel affords similar illustration. This great man was renowned for his piety and wis- dom when he was but a youth. By his interpreting the King of Babylon’s singular dream, he was raised to high dignity in his kingdom. The other officers of the throne, hating his religion, and jealous of his favour with the king, resolved on his destruction. Aware that they could not bring any charge against him, and knowing his inflexible integrity, and his attachment to his God and his religion, they craftily persuaded Darius to enact an unalterable law, that 406 ~ GOVERNMENT OF EVENTS. AFFLICTIONS THE MEANS OF PROSPERITY TO THE CHURCH. whosoever should, for the space of thirty days, ask any favour from either God or man, except of the king alone, should be cast into the den of lions, and be torn asunder. But Daniel was not to be deterred from the worship of his God by these wicked pro- ceedings ; he was therefore more public than ever in the avowal of his religion. His enemies were lying in wait to find an opportunity of criminating him to the king. They succeeded: he was condemned to death ; and was actually thrown into the den of lions. But bis God saved him from injury; the lions were not suffered to hurt him in the least: the king ordered him to be rescued, and his enemies to be thrown in, who were instantly devoured; and Daniel was raised to greater honours than before. “ All things work toge- ther for good to them that love God, to them who are called according to his purpose.” Biography furnishes innumerable instances which show how surprisingly an all-wise Providence has rendered the most awful afflictions subservient to the awakening and conversion of wicked men, and to the spiritual prosperity of the servants of God. How many have been enabled to adopt the language of David, and say, “ It was good for us that we were afflicted ;’—‘‘ before we were afflicted we went astray ; but now have we kept thy word.” TurrpDLty.—Many calamitous events have been permitted to befall the church of God; but Divine wisdom is apparent in rendering them the mean of her prosperity. This truth is so evident from Ee a te a GOVERNMENT OF EVENTS. | A407 ee THE CHURCH IN EGYPT. the history of the church, that it is scarcely needful to dwell upon it. However, I shall mention a few instances. The surprising preservation of the church in Egypt, during upwards of four hundred years of hard bondage, and the most cruel treatment, is a standing miracle.—Hence that singular figure of her ‘state and preservation,—‘“‘ a bush on fire, and yet uunconsumed.” However, her state there was some: thing more than that of mere being; it was that of prosperity ; and prosperity that appeared to-grow out of hardships, slavery, cruelty, and oppression ; for it is testified of the people, “ that the more they were afflicted, the more they multiplied and grew.” In the course of that period the family of Jacob, which consisted of ‘“‘ three-score and ten” persons, increased so astonishingly, that when Moses con-— ducted the people through the Red Sea, they were no fewer than ‘ about six hundred thousand on foot that were men, besides children.” After the day of Pentecost, when so astonishing a revival of religion took place, the disciples re- mained at Jerusalem. Soon an alarming persecution commenced concerning Stephen, which issued in the martyrdom of that holy man, and the scattering of the disciples over all the adjacent regions whither they had fled for safety. What an affecting event! But God makes it subservient to the promoting of his cause. For, wherever the disciples went, they ** preached the Lord Jesus, and the hand. of the 408 GOVERNMENT OF EVENTS. PERSECUTIONS IN THE DAYS OF THE APOSTLES. Lord was with them; and great numbers believed and turned to the Lord.” Each disciple became a preacher, and soon ‘all Judea was filled with their doctrine.” The persecutions aad the diversified evils which were permitted to operate against the Redeemer and his apostles and evangelists, and which were in- tended to destroy their cause by extirpating them, were made the means of exciting a more extensive desire to hear the sentiments which they delivered, and to witness the miracles which they performed; and, consequently, of promoting the knowledge of their purity, their fame, and their influence. Nay, the death of the incarnate Son of God,- which, when Satan and his agents had accomplished, they imagined would have put a period to his cause, was only the means of “ destroying the works of the devil,” and of giving full demonstration of the truth of his Messiahship.—This truth has indeed been so often exemplified in the world, as to give origin to the maxim,“ The blood of the martyrs is the seed of the church.”—-Modern instances innumerable might be added to those which relate to the days of the primitive church, to illustrate this topic :— but enlargement is unnecessary. This statement is ‘Substantiated by thousands of facts. ‘‘ Surely the wrath of man shall praise thee: the remainder of wrath shalt thou restrain.” But let not any one suppose that these obser- vations, which are designed to illustrate the wisdom GOVERNMENT OF EVENTS. | 409 en a a MORAL GOOD ASCRIBED TO GOD. of God in rendering the permission of moral evil, and its various effects, subservient to results of immense advantage to the glorifying of his divine perfections, the good of individuals, and the pros- perity and enlargement of the church, tend, directly or indirectly, to lessen the malignity of sin. It - remains always the same. but in proportion to the evil of its nature, its ruimous operations on the moral faculties of man, and its contrariety to the divine government, is that wisdom apparent which so limits and controls its mischievous effects, as to make them the means of good. However, there are othenkinds of events trans- piring in the world, which we may justly designate aS MORALLY GOOD; they are worthy of a divine interference ; and hence we ascribe their existence immediately to God, Let us proceed to investigate that wisdom which is apparent in events of this description. As it requires less contrivance to render that subservient to a beneficial result which is either good or indifferent in itself, a few brief observations will be enough under this branch of our subject. First.—Wisdom and contrivance are apparent in making events which appear to be unimportant in themselves, the means of originating such as are vast and interesting.—Often large bodies turn upon a small pivot. An inconsiderable ‘spring bubbling up from the earth in some obscure forest, soon receives contributary streams, and expands inta ALO GOVERNMENT OF EVENTS.

The steam- engine, the most important mechanical invention of any age, originated in its being observed that the steam of water, boiling in a tea-kettle, occasioned the lifting up of its lid. The falling of an apple from the tree where it grew, suggested to Sir Isaac Newton the doctrine of gravitation, which enabled him to explain the laws under which all the bodies in the universe move, and according to which all planetary motion is conducted.
