Bolton 1912 PEEFACE On becoming a frequent visitor at the meetings of learned Societies, I was astonished to find that the written records of their deeds were few and far between, and that, with the exception of Weld's " History of the Eoyal Society," but little connected narrative had been produced on a subject of great and increasing interest. Facts of inestimable value lay scattered through endless volumes of *' Trans- actions" and *' Proceedings," but these treasures were not arranged in a form accessible to the general reader. According to my lights I have striven, in unambitious fashion, to supply this gap in the literature of science, and in the little book now offered to the public have attempted to describe in a compact form the rise, progress, and present condition of those great Scientific Institutions of which London — and for that matter England — is justly proud. VI PREFACE. Both in the collection and arrangement of material for these papers — which originally appeared in the columns of Iron — I have received ready and valuable aid from the officers of various institutions, and I take this opportunity of tendering my hearty thanks to Pro- fessor Huxley, to Major Donnelly, to Mr. W. Spottis- woode, and to Mr. Henry Cole; to Mr. H. T. Wood and Mr. Davenport, of the Society of Ai'ts ; to Mr. Walter White, of the Eoyal Society ; to Mr. Whittall, of the Statistical Society ; to Mr. Latimer Clark and Mr. G. E. Preece, of the Society of Telegraph Engineers; to Mr. Trenham Peeks, of the Eoyal School of Mines ; to Mr. Norris, of the Birkbeck Institute ; to Mr. H. W. Bates, of the Eoyal Geographical Society ; to Mr. Forrest, of the Institution of Civil Engineers; and especially to Colonel Charles Manby, to whose frequent counsel and friendly supervision I am deeply indebted. It only remains for me to add that, however much the array of facts in this little volume is due to the courtesy of scientific friends, the only person respon- sible for the opinions advanced is The Author.

The Royal Geographical Society 300 SCIENTIFIC LONDON. I. THE EOYAL SOCIETY. To England belongs the honour of being the first country after Italy to establish a society for the in- vestigation and advancement of physical science. The Koyal Society, the most ancient and illustrious of existing scientific bodies, was founded in 1660. The troubles of the great Kebellion were healed — at least for a time — by the restoration of the Stuarts, and the minds of men, relieved for a while from political anxiety, turned with ardour towards the study of science. " The period had arrived when that experi- mental philosophy to which Bacon had held the torch, and which had already made considerable progress, especially in Italy, was finally established on the ruins of arbitrary figments and partial inductions." B 2 SCIENTIFIC LONDON. By degrees was formed a group of pliilosophers who began to knock at the door of truth, ''at that door which Newton was destined to force open." These were the founders of the Eoyal Society. The road had been admirably prepared by Bacon, and the disciples of the great master of inductive philosophy were not slow in carrying out the plan of a learned society as sketched in the " New Atlantis." Among these were Eobert Boyle, Lord Brouncker, Dr. Wallis, Elias Ashmole — who has given his name to a museum at Oxford — the celebrated Oldenburg, and last, but not least, that Christopher Wren who was destined to replace the old Gothic Cathedral of St. Paul's, which, at the period referred to, was the central spot of busy London, by the present noble structure. As early as 1645, and amid all the turmoil of civil war, a few choice siDirits had been in the habit of assembling for the purpose of discoursing on experimental philosophy, sometimes at Dr. God- dard's lodgings in "Wood Street, and occasionally at the Bull's Head Tavern in Cheapside, where the sacred fire was fanned by the intercourse of kmdred spirits, but owing probably to the unsettled condition of public affairs, nothing was done in the way of organizing a learned body. It chanced, however, that on the 28th November, 1660, several of those who had been in the habit of THE KOYAL SOCIETY. 3 meeting from time to time were assembled at Gresham College, to hear a lecture on astronomy, by Christo- pher Wren, who at that time was one of the resident professors at the old Gresham mansion in Bishops- gate. After the lecture a list of names was drawn up, and the number of members fixed at fifty-five. On the 6th March, 1661, the Society proceeded to the election of a president. The choice of the members fell upon Sir Eobert Moray, who, according to Burnet, was the life and soul of the institution. Sir Eobert being a member of the Privy Council, and in great favour with Charles II., was charged by the king, who, if he never said a foolish thing, certainly did a wise one on this occasion, to assure the growing Society of the royal sympathy and protection. A little more than a year after its foundation the Society was formed into a corporation by • royal charter. It was soon found necessary to amend this document, and a second charter was obtained from the king, and sealed on the 22nd of April, 1663. A third charter, con- ceding to the Eoyal Society Chelsea College, and some additional privileges, was granted in 1669, but the charter of 1663 is still the fundamental law of the Society. This document declares the king him- self to be the founder and patron of the Society, which consists of a president, a council of twenty, and an unlimited number of Fellows. Lord Brouncker was 4 SCIENTIFIC LONDON. the first president, William Ball the treasurer, John Wilkins and Henry Oldenburg the two secretaries, Sir Eobert Moray and the celebrated Boyle members of the council. Lord Brouncker was at this time Chancellor to the Queen, and had already made himself a name by his mathematical studies. Two remarkable discoveries were made by him. He was the first to introduce continued fractions, and to give a series for the quad- rature of a portion of the equilateral hyperbola. The first meeting of the Council after the conces- sion of the new charter took place on the 13th May, 1663, the Society then consisting of 115 members. By the following November the number had increased to 130, of whom eighteen were noblemen, twenty-two baronets and knights, forty-seven esquires, thirty-two doctors, two bachelors of theology, two masters of arts, and eight were foreigners. In August, 1663, King Charles II. presented the Eoyal Society with the mace at present in their possession. This mace — which is made of silver, richly gilt, and w^eighs 190 oz. avoirdupois — fills an important office in the Society. No meeting can be legally held without it, and the same practice respect- ing it prevails in the Eoyal Society as in Parliament. In the House of Commons, when the Speaker is in the chair and the mace on the table, any member THE ROYAL SOCIETY. 5 may rise to address the House. When the Speaker leaves the chair the mace is taken off the table, and when it is carried out of the building the assembly is no longer a House. Great interest attaches to the mace of the Eoyal Society from its having long been supposed to be the identical "bauble" removed by the command of Ohver Cromwell. This, however, has been shown by Mr. Weld to be an erroneous belief. The royal mace used during the reign of Charles I. was broken up with the rest of the crown jewels, and an entirely new mace was made for the Commonwealth. This was ornamented with flowers instead of the cross and ball at the top, with the arms of England and Ireland instead of those of the late king. The mace, still in the possession of the Eoyal Society, is a truly royal one, consisting of a stem handsomely chased with a running pattern of the thistle, terminated at the upper end by an m^n-shaped head surmounted by a crown, ball, and cross. On the head are embossed figures of a rose, harp, thistle, and fleur-de-lys, on each side of which are the letters C. E. The year 1664 was marked by great acti^dty in the Eoyal Society. Eight committees were formed for prosecuting researches in different directions. In the month of June Sir John Cutler founded a chair of Mechanics, and, with the consent of the Eoj^al Society, 6 SCIENTIFIC LONDON. lie assigned to the celebrated Hooke a ]3ension of fifty pounds a year, leaving to the Society the care of fixing the number of lectures and their subject. Hooke was also made curator, with a salary of thirty pounds, and apartments were assigned him in Gresham College, where the Society continued to hold its meetings. On the 6th March, 1665, appeared the first number of '' Philosophical Transactions." This rej)ort was published by Oldenburg, and submitted to the Council of the Society. During this year the plague proved a serious interruption to the weekly meetings of the Society, and actually compelled Oldenburg to get the seventh and eighth numbers of the '* Transactions" printed at Oxford, on account of the impossibility of finding printers in London. Meetings were held at uncertain intervals until February, 1666. On the 21st of this month the Society met again at Gresham College, under the presidency of Lord Brouncker, and a noteworthy event took place. It was decided that a gift of one hundred pounds made to the Society by Mr. Colwall, should be employed in purchasing a collection of rarities found by Mr. Hubbard. This collection was the nucleus of a museum, which became in time the richest in London. Many presents came to Oldenburg from abroad, the correspondence of this active member having assumed immense proportions. Among the THE ROYAL SOCIETY. 7 curious objects in this collection was ''the skin of a Moor, tanned, with the beard and hair white ; " but more worthy of observation was "a clock whose move- ments are derived from the vicinity of a loadstone," and so adjusted as to " discover the distance of countries at sea by the longitudes." This clock and Hooke's magnetic watch were apparently the pearls of the collection, and the direct ancestors of the electrical clock of the present day. The great fire of London produced a temporary migration of the Eoyal Society. It is true that they were not actually burnt out of Gresham College, but that building was seized upon as a temporary Ex- change, and the philosophers, elbowed out of the City, found hospitable welcome at Arundel House. Henry Howard, afterwards Duke of Norfolk, not content with putting his house at the disposition of the Society, presented them with a magnificent library, the germ of which was formed by Matthias Corvinus, King of Hungary. In 1667, at Arundel House, was performed the remarkable experiment of transfusing the blood of a sheep into the veins of a man, the subject of the operation being a poor devil of a student named Arthur Coga, who for the consideration of one guinea of the lawful money of the realm consented to lose eight ounces of his own blood and receive into his 8 SCIENTIFIC LONDON. veins fourteen ounces of slieep's blood. Pepys saw this Coga at a tavern, and describes him " as a Httle frantic, a poor debauched man." The experiment, if in corpore vili, was attended with no evil consequences to the patient, which is more than could be said for the Continental experiments made about the same time, which caused the death of sundry persons, and brought the transfusion of blood into complete dis- credit. The mechanical science of the Society found ample recognition at Court, Catharine of Braganza requesting this learned body to produce for her use a thermometer, which was duly made by Hooke. The year 1671 was marked by the rise of the greatest luminary of the Eo^^al Society. A young candidate was proposed for the honour of fellowship, one Isaac Newton, professor of mathematics at the University of Cambridge. Newton had already made his mark, having invented the reflecting telescope. The actual instrument constructed by his own hands is now in the possession of the Eoyal Society, and is justly esteemed one of its most precious relics. Newton was elected on the 11th of January, 1672, and on the 8th of February communicated to the Society his researches into the nature of light. The publication of these inquiries in the "Transactions" aroused a storm of opposition. Hooke in England, and Huyghens abroad, attacked THE KOYAL SOCIETY. 9 not only his conclusions, but the accuracy of the experiments on which they were based. Although much harassed by the controversy, Newton replied within a few months in a manner which firmly estab- lished his general doctrines. Among the secretaries of this period figures the name of John Evelyn, and among the foreign corres- pondents the celebrated Leuwenhoeck, in whose hands the microscope finally became a useful scientific instrument. Leuwenhoeck not only transmitted his valuable observations to the Eoyal Society, but bequeathed to that body twenty-six microscopes, the glasses of which he had polished himself. Great names now appear on the roll. Flamsteed, a Fellow of the Society, was appointed astronomical observer at Greenwich. Two years later Edmund Halley was also elected a Fellow on his return from St. Helena, where he had been observing the stars of the Southern hemisphere. In 1684 Dr. Denis Papin — the inventor of the famous Digester — was named curator, on condition of making an experiment at every general meeting of the Society ; and the year is also remarkable as that in which Samuel Pepys was elected president. Of no " considerable " family, being actually the son of a tailor, this remarkable man and delightful gossip was educated at St. Paul's School, and at Trinity College, Cambridge, where he 10 SCIENTIFIC LONDON. left no particular mark. In 1655, when only twenty- three years of age, he married a girl of fifteen, to whose family connections he possibly owed part of his advancement. Twenty-nine years later he took his seat as president of the Eoyal Society. No date is more justly celebrated in the annals of this august Society than that of the 28th of April, 1686. At the ordinary meeting held on that day, Dr. Vincent presented the manuscript of the first book of the immortal work of Newton, " Philosophise Naturalis Principia Mathematica." The Society wished to print, at its own expense, the work which was dedicated to it, but the finances of the institution had been so terribly depleted by the pubhcation of Willoughby's " Be Historia Piscium," that even the salaries of the regular officers were in arrear. Members did not pay their subscriptions, and some of them, like Newton, were specially exempted from pay- ment of the yearly fifty-two shillings, on account of the inadequacy of their means. Finally, Halley took the risk of publishing the " Principia " on his own shoulders, a deed sufficient to immortalize him had he done nothing fm^ther for the advancement of science. When it is remembered that the volume contained sixty-four sheets, and above a hundred diagrams cut in wood, it is wonderful that Halley should have performed the laborious task of editing it in about six THE EOYAL SOCIETY. 11 months. Halley's troubles were added to very consider- ably by the reluctance of Newton to publish the third book of the ^^Principia" — ''De Systemate Mundi." Hooke, perhaps the greatest mechanical genius of his own or any other age, felt himself outraged by Newton having omitted in his preface all mention of him. Halley writes to Newton in May, 1686, that " Mr, Hooke has some pretensions upon the invention of the rule of decrease of gravity being reciprocally as the squares of the distances from the centre. He says you had the notion from him, though he owns the demonstration of the curves generated thereby to be wholly your own. How much of this is so you know best, as likewise what you have to do in this matter." In reply to this Newton declared his inten- tion to suppress the third book altogether, and said, " Philosophy is such an impertinently litigious lady that a man had as good be engaged in lawsuits as have to do with her. I found it so formerly, and now I am no sooner come near her again than she gives me warning." Halley's invincible arguments and entreaties fortunately prevailed on Newton not to suppress the third book. The entire work was written by Newton in about a year and a half, and was, as we have seen, hurried through the press by the indefatigable Halley. It is depressing to find that the circulation of the first 12 SCIENTIFIC LONDON. edition was undoubtedly small, inasmuch as in 1692, when the reputation of the "Principia" was established, Huyghens, who was anxious for a second edition, was of opinion that two hundred copies would suffice. The volume contains the dedication to the Eoyal Society, a brief preface, verses by Halley in honour of Newton, definitions, axioms, a short book on unre- sisted motion, a second on resisted motion, and a third on the system of the universe. " Halley's verses," says Mr. Weld in his ''History of the Eoyal Society," " were somewhat altered by Bentley in the second edition, but the original readings were very nearly restored in the third." The publication of the " Principia" was licensed by the Eoyal Society on the 30th June, 1686, and the imprimatur signed by the ubiquitous Samuel Pepys, is dated on the fifth of the following month. The manuscript of the immortal " Principia," entirely written by Newton's own hand, is in admirable preservation, and is justly considered the greatest treasure in the possession of the Eoyal Society. In the years 1687-88-89, numerous important inventions were presented to the Society by Hooke, Halley, and Papin — Hooke especially pursuing his astronomical investigations with a huge telescope mounted at Gresham College. On the 14th June, 1699, was exhibited to the Society THE ROYAL SOCIETY. 13 a model of Savery's condensing steam-engine. In the minutes it is recorded that " Mr. Savery entertained the Society with showing his engine to raise water by the force of fire. He was thanked for showing the experiment, which succeeded according to expectation, and was approved of." Savery presented the Society with a drawing of his engine, still preserved among the Society's collection of prints and drawings, and entitled, " An Engine for Eaising Water by Fire," by Thomas Savery. Doubtless Savery had a predecessor in the history of steam, but it will be remembered that although the Marquis of Worcester invented the steam-engine " to drive up water by fire," seen by Cosmo de Medici, Grand Duke of Tuscany, in opera- tion at Yauxliall in 1656, we are indebted to Savery for the introduction of a vacuum which enabled his engine to perform double the work of that invented by the Marquis of Worcester. On the 11th February, 1708, Newton then being President of the Eoyal Society, a proposition was submitted " concerning a new-invented boat to be rowed with oars moved by heat." At the two ensuing meetings the matter w^as again brought forward, accompanied by letters of recommendation from Leibnitz. Papin says that, inasmuch as "it is certain that it is a thing of great consequence to be able to apply the force of fire for to save the labour of men," 14 SCIENTIFIC LONDON. and 4hat "the Parliament of England granted some years ago a patent to Esquire Savery for an engine he had invented for that purpose, and his Highness Charles, Landgrave of Hesse, hath also caused several costly experiments for the same design," he therefore offers with all dutiful respect " to make here an engine after the manner that has been i^ractised at Cassell, and to fit it so that it may be applied for the moving of ships." Dr. Papin wished much to make " the said Cassellian engine at his own cost," but was unable to furnish the necessary funds. The Eoyal Society was unfortunately in a similar position. Papin clearly saw that ships might be propelled by paddles moved by steam. In a paper published as early as 1690 in the " Acta Eruditorum," he says, " Without doubt oars fixed to an axis could be made most conveniently to revolve by om- tubes. It would only be necessary to furnish the piston-rod with teeth, which might act on a toothed wheel properly fitted to it, and which, being fixed on the axis to which the oars were attached, would communicate a rotary motion to it." Despite the squabbles between Newton and Flam- steed, the Eoyal Society waxed mighty under the pre- sidency of the author of the " Principia." On the death of Sir Godfrey Copley, in 1709, the interest of one hundred pounds became vested in the Society. THE EOYAL SOCIETY. 15 For awhile this sum was given to the curator to pay the expenses of experiments, but was finally em^Dloyed in striking a gold medal of the value of five pounds, to be given to the author of the best experiment made during the year. This medal is the greatest honour at the disposal of the Eoyal Society. It has been given for a century and a quarter to the authors of the most brilliant discoveries made in England and on the continent of Europe. The first Copley medal was awarded to Stephen Gray — a name almost for- gotten until Dr. Eichardson, only the other day, vindi- cated the claim of the first Copley medallist to the title of father of electrical science. Among the medallists are found the names of Benjamin Franklin, James Bradley, John Dollond, and John Smeaton, of Cavendish, Priestley, Maskelyne, Hutton, Hunter, Rumford, Volta, Attwood, Astley Cooper, Wollaston, Da^'y, Brodie, Brande, Brewster, Buckland, Arago, Faraday and Leibig, Herschel and Leverrier. Towards the middle of the last century the Eoyal Society took an active part in promoting the change of style effected in England on the 2nd of September, 1752. A few years later active measm^es were taken for observing the transit of Venus, which, according to the prediction of Halley, was to occur in 1761. The importance of this event in determining the exact distance of the sun from the earth induced the 16 SCIENTIFIC LONDON. treasury to give ^91600 for the expedition to St. Helena conducted by Nevil Maskelyne, but bad weather interfered with the success of the observation. This loss, however, was recovered eight years later, when Messrs. Green and Banks (afterwards Sir Joseph) sailed for Tahiti with Captain Cook in the Endeavour, and obtained their observations on a cloudless day. The year 1784 was marked by a grand discovery — that of the composition of water, attributed by some to Cavendish and by others to Watt. Doctors dis- agree severely on this vexed question. It will suffice to remark that Arago, Dumas, and Berzelius favour the claims of Watt, while Whewell, Peacock, and Brown rule for Cavendish. The early part of the present century was marked in the Eoyal Society by the advent of Sir Humphrey Davy. In 1806 he read his celebrated paper " On some Chemical Agencies." " This," says Whewell, *' was a great event, perhaps the greatest event of the epoch." Although the war between England and France was at its height, Davy's work was crowned by the Institute of France, and the author was presented with a prize of three thousand francs. Davy now devoted his attention to the illumination of mines, and discovered the safety lamp, the originality of which was, as appears to have been the case with almost every scientific invention, contested at the time. THE ROYAL SOCIETY. 17 Nevertheless, the honours of discovery were awarded to Davy by a committee of the Eoyal Society, and the colHery proprietors presented him with a service of plate valued at £2500. In addition to this solid reward all the honours of the Eoyal Society were showered upon the illustrious chemist. He received the Copley medal, the Eumford medal, delivered the Baker Lecture several times, and in 1820 took his seat as president in the chair whilom occupied by Wren, Newton, Sloane, and Banks. - From its founda- tion to the present time the Eoyal Society has thus numbered many illustrious names among its presi- dents, from Lord Brouncker to Dr. Hooker, and during the two centuries of its existence has occupied various dwellings — Gresham College, then Arundel House, then Gresham College again, then a house in Crane Court, then Somerset House, and lastly, after many migrations, has found a home at Burlington House, the handsome building extending from Burlington Gardens to Piccadilly. The Society receives house room, but nothing beyond that, from the Government of the country, being now, as always, an entirely self- supporting institution. It is true that a thousand pounds a year are voted for the encouragement of original research ; but the Eoyal Society only advise the Ministry of the day as to the manner in which this sum should be employed. A Special Committee 18 SCIENTIFIC LONDON. of the Society is appointed to recommend the method of distributing this fund, but no portion of it finds its way into the coffers of the Society. Eooms are also provided in the wings of Burlington House for the Society of Antiquaries, the Linnasan Society, the Geological Society, the Eoyal Astro- nomical Society, and the Chemical Society. The Koyal Society has on the first floor a handsome suite of reception-rooms — available for the annual soirees of the president — and a library affording space for 35,000 volumes. On the ground floor is a hall, an ante-room, and the room in which the Society holds its meetings. These take place once in every week from the third Thursday in November to the third Thursday in June. A record of these meetings is preserved in the octavo " Proceedings," and the best papers are printed in the quarto "Transactions." These last have been regularly printed since their institution in 1665, the series now extending to 160 volumes. The Society has at its disposal four medals by which to mark its appreciation of scientific investiga- tions and remarkable discoveries. The first award of the Copley medal was made in 1731, and of the Kumford medal in 1800, to the founder himself, Benjamin Count Eumford, for his various discoveries in respect of light and heat. In the year 1825 THE ROYAL SOCIETY. 19 George IV. communicated through Sir Kobert Peel his intention "to found two gold medals of the value of fifty guineas each, to be awarded as honorary- premiums under the direction of the President and Council of the Koyal Society, in such manner as shall by the excitement of competition among men of science seem best calculated to promote the objects for which the Eoyal Society was instituted." The two first medals were awarded in 1826 to John Dalton and James Ivory. William IV. and her present Majesty have continued the gift of these Eoyal medals, and they are therefore annually awarded. The total number of Fellows, including foreign members (limited to fifty), is now 571. Besides the mace already mentioned, and the reflecting telescope made by Newton, the Society's treasures include the sun-dial cut by the great philosopher, when a boy, in the wall of his father's house, and a large collection of the portraits of Presidents, distinguished Fellows, and other great luminaries of science, painted by Van Somer, Sir Peter Lely, Sir Godfrey Kneller, Sir Joshua Keynolds, Sir Thomas Lawrence, and other great artists. These pictm-es are dispersed throughout the rooms occupied by the Society. On the first floor one of the most remarkable portraits is that of Copernicus, who, after travelling over Europe, studying astronomy at 20 SCIENTIFIC LONDON. Bologna, and filling tlie Chair of Mathematics at Eome, settled down in his quiet canonry at Frauen- burg, and at length embodied the result of his labours in the celebrated treatise, ''De Orbium Coelestium Eevolutionibus," to the publication of which he only consented a short time before his death — having probably a keen presentiment that the Copernican system would cost him his canonry, if not his life. The clean-shaven, priestly face is certainly a remark- able one, with the long upper lip and portentously long, sharp chin, so often found in men of genius. Near him hangs George Buchanan, a bald and grizzly- bearded Scot, looking mighty solemn at the neigh- bourhood of that bright black-haired Frenchman, Descartes. Not far from these worthies may be seen the portrait of Flamsteed — the first Koyal ''Astro- nomical Observator," to whom mankind is indebted for that enormous mass of astronomical observations which furnished the first trustworthy account of the fixed stars. The harsh, rugged features of Galileo next arrest attention, and after contemplating his worn face the eye rests complacently on the picture of Dr. Bradley, whilom Astronomer Eoyal, and the very heau ideal of a prosperous Churchman. Enthroned in an attitude of tremendous dignity, Edmund Halley looms on the wall — a don every inch of him, but an industrious secretary withal, and the composer of no THE ROYAL SOCIETY. 21 less than eighty-one papers, published in " Philo- sophical Transactions," on subjects connected with 023tics, mechanics, mathematics, astronomy, mag- netism, the law of mortality, &c. The great Hobbes looks every inch a Puritan, albeit his works enjoyed in his own day a very similar reputation to those of Strauss in our own time. John Locke, his great successor, appears in an admirable picture by Kneller, and John Evelyn looks sadly forth from Kerseboom's canvas. The effect of gazing upon this galaxy of worthies is an inexpressible feeling of smallness in the gazer, who is glad to change the scene and descend to the ante-room, where he is restored to a more comfortable frame of mind by the contem- plation of the gracious features of his Majesty King Charles II., the amiable, if erring, monarch, who apologized to his courtiers for being such an "uncon- scionable time in dying." The portrait by Lely depicts the jovial monarch in anything but evil case. The large eyes and drooping eyelashes give a thought- ful look to a face which, were it not for the bright scarlet over-full underlip, might well be taken for that of a philosopher. In one feature — the long nose — the kingly countenance is quite in keeping with the scientific visages ranged around — a preponderance of nose being remarkably characteristic of great thinkers — Newton, Locke, Boyle, and many others being 22 SCIENTIFIC LONDON. gifted with an enormous quantity of that useful organ. So well was the necessity for an important nose recognized by Tycho Brahe, that that great astronomer, having had the misfortune to lose a portion of his in a duel, supplied the loss by an artificial nose made of gold, so well-formed and coloured as to be hardly distinguishable, it is said, from the natural feature. In his portrait, however, the nose of Tycho Brahe looks odd enough, and gives a singular expression to a countenance finished off by a pointed beard, and adorned with a pair of portentous moustaches. Near the portrait of the Eoyal founder hang the pictures of the late Duke of Sussex and of Earl Eosse, the builder of the famous telescope. On entering the large room, the well-known features of Newton are discovered in the central place of honour, over the chair occupied by the president. On the right of Newton is the sad, weary-looking countenance of Eobert Boyle, and the handsome features of that genial-looking cavalier. Lord Brounc- ker. Farther on is descried the dark bourgeois face of our old friend Samuel Pepys, — almost smothered in a tremendous full-bottomed wig, — near whom looms large the Johnsonian figure of Sir Joseph Banks, adorned with the star and riband of the Bath. Here is Sir Christopher "Wren, also much bewigged, turning his back on St. Paul's, and there, in all the glory of tights THE ROYAL SOCIETY. 23 and Hessians, the figure of Dr. WoUaston, rendered famous by his researches into electricity and galvan- ism, and rich by his discovery of the method of making platinum malleable. A sense of awe again creeps over the visitor as he contemplates the massive heads which have contributed so much to the well- being of mankind. It will be seen that a visit to the halls of the Eoyal Society is not an expedition to be undertaken lightly, or in an irreverent spirit. He who seeks to be admitted to the sacred penetralia, where science sits enthroned among her chosen votaries, feels very much as he did on his first visit to the House of Lords, an institution which has much in common with the Eoyal Society. The would-be visitor must first look up a friendly F.E.S., who, if the applicant be deemed worthy, will introduce him either personally or bj' letter to the acting secretary, Mr. White, who will enter his name on the book, bracketed with the name of the introducer, and he will now only have to present himself at the fashionable hour of 8.30 to be at once admitted to the Upper House of Science. Having fulfilled these conditions, I presented myself at Burhngton House on one of those foggy evenings for which London is recovering its ancient notoriety. Having deposited my coat and hat with a careful attendant, I found myself in the spacious ante-room. 24 SCIENTIFIC LONDON. gazing on the dark features of his Majesty King Charles II., who, albeit of an over gay and festive turn of mind, had probably acquired a certain dilettante taste for science from his dashing relative, that ring- leted Prince of Bohemia, who — equal to either fortune — led a charge of cavalry in the field, or conducted a scientific experiment in the quiet recesses of his laboratory with equal success. This same " Kupert's drop," the scientific toy destined to immortalize its inventor, affords grave matter for reflection to those endowed with a philosophic temperament. The heroes of Long Marston Moor and Naseby, dashing Cavaliers and sturdy Eoundheads, have long since rendered back to earth the strength which they drew from her mighty bosom. As the world whirls on their names will wax dim enough in the page of history, but '' Eupert of the Ehine " has written his name in indelible characters on the records of scientific discovery. The members are now dropping in one by one, and are chatting pleasantly in groups, or examining speci- mens and photographs of curious organisms brought by a distinguished Fellow, who is the happy possessor of a sun-picture of the gigantic octopus recently washed ashore at Newfoundland. Thoughtful-looking, grey-haired men are the majority of the F.E.S., but active withal, and evidently men to whom hard work THE ROYAL SOCIETY. 25 and constant study have become necessary stimulants. For the nonce they put on a hoUday ah% as if bent on enjoying a little bit of scientific dissipation, and resolved to make a scientific night of it. But the clock points to half-past eight, the hom^ at which proceedings commence, and punctually to the moment the audience settle down here and there, while the president proceeds to take the chair. On a dais placed immediately beneath the portrait of Newton, at the upper end of the room, sits the president, enthroned in a massive chau*, evidently made " on the lines " of Sir Joseph Banks, and affording ample room for Dr. Hooker, whose spare figure and study-worn face are surmounted by a pair of those bushy eyebrows which so frequently add force and character to the features of those deeply learned in the law and those other sciences to which Mr. Ayrton recently declined to concede any priority over jurisprudence. Before the president lies the mace, without which no regular meeting can be held. On his right sits Professor Stokes, Lucasian Professor of Mathematics, the senior secretary, and on his left sits, or rather recUnes in his armchaii', one who has done much to gild the pill of science and make it acceptable to the many — Professor Huxley. A short paper is read in the absence of the contributor by the junior secretary, and duly committed to the archives 26 SCIENTIFIC LONDON. of the Society, after which ceremony the meaning of some compHcated clockwork on the table is made manifest. The inventor of the instrument — Professor Eoscoe — steps up to the table at the invitation of the president, and explains the machine in question, a clever contrivance for measuring automatically the strength of the actinic rays of the sun, by means of a roll of sensitive papers, successive portions of which are unwound, exposed to the light for a certain time, and reeled off, thus preserving a record of the inten- sity of the chemical rays during various periods, of the day. At the conclusion of the exposition, the president invites discussion, and the Fellows, nothing loth, attack the subject vigorously. The reader of the paper having replied to the objections brought forward, is formally thanked by the Society, and his invention duly recorded in the archives. Another paper is read on Explosive Compounds, the con- ductivity of concussion by rough and polished tubes, and more especially on the extraordinary power of water in transmitting the shock of an explosion to an immense distance. This subject provokes a lengthened and lively discussion, at the conclusion of which the meeting comes to an end ; the chairman rises, the mace is removed, and the learned Fellows abandon themselves to tea and scientific gossip. ( 27 ) 11. THE KOYAL INSTITUTION. That stronghold of fashionable science, the Eoyal Institution in Albemarle Street, covers a site of great historical interest. In 1665, when the space now occupied by Arlington Street was taken up by the gardens of Goring House, three stately villas were in course of erection on the opposite or north side of Piccadilly. Between Burlington House on the east — built originally by the Sir John Denham who poisoned his beautiful wife — and Berkeley House on the west, the entire space was occupied by the stately mansion built by Lord Chancellor Clarendon. Pepys, of course, went to see it while building, and has a prime bit of scandal: ''the common people have already called it Dunkirk House, from their opinion of his having a good bribe for the selling of that town." John Evelyn — a partial critic, inasmuch as he had had a hand in its internal adornment as well as in laying out the 28 SCIENTIFIC LONDON. gardens — declared that he had *' never seen a nobler pile " than that occupied by Lord Clarendon until his flight after he had been deprived of the great seal. It was a short-lived palace. The Chancellor dying in exile, the Earl, his successor, sold ''that which cost ^50,000 building to the young Duke of Albemarle for ^25,000, and ultimately this stately pal^e," says Evelyn, was ''decreed to ruin, to support the pro- digious waste the Duke of Albemarle had made of his estate since the old man died." He sold it to the highest bidder, and it fell to "certain rich bankers and mechanics, who gave for it and the ground about it ^£35,000 ; they design a new town, as it were, and a most magnificent piazza. 'Tis said they have already materials towards it, with what they sold of the house, alone more worth than what they paid for it. See the vicissitude of earthly things ! I was astonished at the demolition, nor less at the little army of labourers and artificers levelling the ground and con- triving great buildings, at an expense of £200,000 if they perfect their design." Bond Street, Dover Street, and Albemarle Street were the result of the venture of the "bankers and mechanics," who were shrewd enough to descry, more than two hundred years ago, that cities follow the sun and march westward. Commencing with the nineteenth centuiy, the Eoyal Institution can claim for itself many of the THE ROYAL INSTITUTION. 29 most remarkable discoveries which have distinguished an era of unrivalled activity. It owes its origin partly to Sir Joseph Banks, but in a far greater degree to a more remarkable man. Benjamin Thompson, afterwards Count Eumford, was a lineal descendant of one James Thompson, who figured at Charlestown in Winthrop's company in 1630. Born in his grand- father's farmhouse, he enjoyed the advantage of a good grammar-school education, and then advanced in the world by the steps familiar to this day in America, but almost unknown in Europe. He was apprenticed to an importer of British goods, was allowed to make small ventures on his own account, fancied that he had invented perpetual motion, took a great interest in questions relating to light, heat, and the wind, lost his place, and blew himself up with fireworks before the age of sixteen. At seventeen he was a dry-goods clerk in Boston, studied French during his evenings, and got himself an electrical machine with money earned by cutting and carting firewood. He then boarded for some eighteen months with a Dr. John Hay, and picked up a little anatomy, chemistry, surgery, and physic, and in 1771 went to Cambridge, Massachusetts, to attend Winthroj)'s lectm-es on Experimental Philosophy. He then, after the manner of his country, ''taught school" at Wil- mington ; and afterwards became master of a school 30 SCIENTIFIC LONDON. at a place originally called Kumford, but afterwards re-cliristened Concord, when the disputes as to the State to which it belonged were finally settled, and it was ceded to New Hampshire for good and all. Shortly before attaining the age of twenty, Thomp- son, a fine, handsome young man, married — or, to use his own expression — ''was married by" Mrs. Eolfe, a wealthy widow of Concord. There was now no more occasion to " teach school," and Thompson hoped for leisure to pursue science vigorously; but the American Eevolution breaking out, he speedily found his way to England, in 1778 was elected a Fellow of the Eoyal Society, and two years later became an Under Secretary of State, and Colonel of the King's American Dragoons. At the conclusion of the war he was knighted by George the Third, and, having met the Elector of Bavaria at Strasbourg, passed a considerable time in Munich, busying him- self in improving the breed of cattle and in building workhouses, and it was in order to find the most economical method of lighting the workhouse in Munich that he initiated the series of experiments afterwards embodied in a paper on "The Eelative Intensities of the Light emitted by Luminous Bodies," read before the Eoyal Society. Honours now fell thicldy upon the successful American. In 1785 he was elected member of the THE EOYAL INSTITUTION. 31 Bavarian Academy of Sciences, and in the two succeeding years was made a member of the Berlin Academy of Sciences and received the order of St. Stanislaus. Finally, Sir Benjamin Thompson became Lieutenant-General of the Bavarian Armies, received the order of the White Eagle, and was made a Count of the Holy Eoman Empire. After the death of his wife he travelled for sixteen months in Italy, and during his stay at Verona rebuilt the kitchens of the two great hospitals — La Pieta and La Misericordia. Seven-eighths of the firewood were saved, and his success in this enterprise appears to have greatly encouraged Count Kumford to pursue his investigations into the proper management of fuel. A curious essay written by him about this time contains the mixed philanthropic and philosophic germ of the Eoyal Institution. This is a " proposal for forming in London, by private subscription, an establishment for feeding the poor and giving them useful employ- ment, and also for furnishing food at a cheap rate to others who may stand in need of such assistance, con- nected with an institution for introducing and bringing forward into general use new inventions and improve- ments, particularly such as relate to the management of heat and 'the saving of fuel, and to various other mechanical contrivances by which domestic comfort and economy may be promoted." This was followed 32 SCIENTIFIC LONDON. by other essays on '' Food and Feeding the Poor," on '^ Eumford Soup and Soup Kitchens," and on "Chimney Fireplaces." The Eumford medal was now presented to the Eoyal Society " for discoveries tending to improve the theories of fire, of heat, of light, and of colours, and to new inventions and con- trivances by which the generation and preservation and management of heat and of light may be pre- served." The endowment of the medal consisted of dBlOOO stock, and was, I may add, presented on the first award, in 1802, to its founder. Meanwhile Eumford went to Ireland and fitted up laundries and model kitchens, cottage fireplaces, and model lime- kilns ; served in Bavaria, preserving by his firmness and skill the neutrality of that country ; and finally determined to return to America, but was deterred from carrying out this project by his anxiety to launch the Eoyal Institution. In the mind of Eumford the dominant idea was originally that of bettering the condition and increasing the comforts of the poor. A society was formed for this purpose, and out of it sprang, from a proposal of Count Eumford, a scheme for forming a new "Establishment in London for Diffusing the Knowledge of Useful Mechanical Im- provements." The two great objects of the institution were declared to be the diffusion of the knowledge aforesaid, and the teaching of the application of THE ROYAL INSTITUTION. 33 scientific discoveries to the improvement of arts and manufactures in this country. To fulfil the first object were to be exhibited full-sized working models of fire- places, kitchens, stoves, grates, boilers, coppers, &c., and smaller models of houses, bridges, spinning-wheels, and of all " such other machinery and useful instru- ments as the managers of the institution shall deem worthy of the public notice." In order to carry into effect the second object of this institution — namely, '^ teaching the application of science to the useful purposes of life" — a lecture-room was to be fitted up " for philosophical lectures and experiments, and a complete laboratory and philo- sophical apparatus, with the necessary instruments, will be provided for making chemical and other philoso]3hical experiments." On the 7th March, 1779, a meeting was held at the house of Sir Joseph Banks, at which the list of original fifty-four proprietors and subscribers of fifty guineas was read. In addition to the names of Eumford and Banks are found on this list those of Angerstein, Joseph Grote, the Duke of Devonshire, Earl Spencer, Earl Holland, Lord Palmerston, the Earl of Winchelsea, and William Wilberforce. By the end of June, 1801, the Eoyal Institution had received upwards of twenty thousand pounds in subscriptions. The site of four houses had been purchased in Albemarle Street, professors of 84 SCIENTIFIC LONDON. chemistry, physics, and mechanics had been engaged, daily lectures were delivered, a spacious chemical laboratory had been erected, workshops for making models had been built, and skilled workmen engaged for making apparatus and models of various kinds. Early in this year Count Eumford wrote to his daughter that the Eoyal Institution was " not only the fashion but the rage," and mentions incidentally that *' we have found a nice, able man for this place as lecturer — Humphry Davy." This " nice, able man " was the eminent philosopher destined to explode a great part of Eumford's scheme, his models, his fire- places, his kitchens, his experimental cooking, and his experimental dinners. In 1802 Count Eumford forsook England for Bavaria — as it turned out, for ever — and, like many other benefactors of his species, was considered a good riddance. So far as can be ascertained, the American-Bavarian Count was offen- sively dictatorial in his manner, and exasperated those whom he did not succeed in crushing. Having shaken off Dr. Garnett, the first professor of chemistry at the Eoyal Institution, he engaged Davy as an assistant lecturer in chemistry, director of the labora- tory, and assistant editor of the journals of the Institution. The future president of the Eoyal Society was granted a room in the house, coals, candles, and a salary of 100 guineas per annum. THE EOYAL INSTITUTION. 35 The first interview of Davy with Count Eumford was not very agreeable to the young chemist, then in his twenty-third year. The intensely juvenile air of the candidate, his almost provincial manners,' and a slight Cornwall accent, sufficed to reduce the glacial Count to a lower temperature than usual. With con- siderable difficulty Davy obtained permission to give a few lectures on the properties of gases. This, however, was sufficient. At the first lecture the variety and ingenious combination of his ideas, and the fire, vivacity, clearness, and novelty with which they were expounded, enchanted the few who came to listen to the young lecturer, in whom they found united the power of poetry, oratory, and philosophy. The second lecture was crowded, and his course was obliged to be removed to the large amphitheatre, whither his fervid genius, and in some degree his youth and good looks, drew immense audiences. The ladies were charmed by the handsome young lecturer, and never tired of praising the beauty of his eyes, which they declared were " made for something besides poring over crucibles." Before coming to the Eoyal Institution, Davy had already attained a certain celebrity by discovering the anaesthetic properties of nitrous oxide, and the period of his professorship was signalized by many brilhant discoveries. Named titular professor of chemistry 36 SCIENTIFIC LONDON. in 1802, lie only resigned the chair in 1813. He delivered his last lecture on the 9th April, 1812, the day after he was knighted by the Prince Eegent, and the day before his marriage with Mrs. Apreece, a wedding which put him in possession of a large fortune. The splendour shed upon the Eoyal Institution by the new professor of chemistry prevented the exhibition of any regret at the entire alteration of the original plan of the establishment. The Institution was no longer a popular school of technical science, but became almost the exclusive property of the higher classes. Ladies of the highest rank, and young noblemen, assiduously followed the lectures of Davy, while his researches in the laboratory produced the most solid results. It was there that he discovered the laws of electro-chemical decomposition, and succeeded in decomposing fixed alkalis — that he established the true nature of chlorine and the philosophy of flame. The electric battery with which the separation of potassium and sodium was operated is still preserved in the Eoyal Institution along with other apparatus used by Davy. The delight of the investigator, on seeing the globules of the new metal start through the crust of potash and catch fire on contact with the air, was intense. '' He could not contain his joy, and danced round the room in an ecstatic transport ; it was only after a while that he recovered sufficient THE ROYAL INSTITUTION. 37 calmness to continue the experiment." An immense electric battery was now constructed, and this heavy artillery directed against resisting earths. The result of experiment was to add four new metals to the list — barium, strontium, calcium, and magnesium. On resigning the chair of chemistry, Davy declared that he only renounced teaching in order to devote himself to original investigation, but after this date his life was only marked by one great discovery — that of the safety-lamp which bears his name. In the year marked by the rising of that brilliant star. Sir Humphry Davy, the directors of the Eoyal Institution made another great success by appointing to the chair of natural philosophy a man of tran- scendant genius, the celebrated Dr. Young. He was one of the few infant prodigies who have made a mark in after-life. At two years of age he could read. At four he could recite by heart numerous English and Latin poems, of which last, by the way, he did not then understand a word ; but by the age of four- teen he had learned — besides Greek and Latin — French, Italian, Hebrew, Persian, and Arabic. His passion for learning was immense, and his talent for overcoming difficulties astounding. On reaching man's estate he was an accomplished linguist, a brilliant mathematician, a botanist, a skilful musician, a neat turner, and a daring circus rider. This uni- 38 SCIENTIFIC LONDON. versal genius did not remain long at the Eoyal Insti- tution, but yet had time to deliver a notable course of lectures on Natural Philosophy before his retire- ment, when his place was occupied by Dalton. The famous author of the Atomic Theory was surprised, like other people, at the youthful appearance of Davy, and writes, characteristically enough: — " He is a very agreeable and very intelligent young man, and we have extremely interesting conversations of an even- ing ; his principal defect — as a philosopher — is that he does not smoke." Although in the foremost rank of scientific men, Dalton was far from achieving great success as a lecturer, being almost utterly devoid of the fluency and power of illustration possessed in such a remarkable degree by Davy and Faraday. A most amusing ac- count was given by Babbage of the incidents attending the presentation of Dalton at Court. Firstly, he was a Quaker, and would not wear the sword, which is an indispensable appendage of ordinary Court dress. Secondly, the robe of a Doctor of Civil Law was known to be objectionable on account of its colour — scarlet — one forbidden to Quakers. Luckily, it was recollected that Dalton was afflicted with the peculiar colour-blindness which bears his name, and that, as the cherries and the leaves of a cherry-tree were to him of the same colour, the scarlet gown would THE ROYAL INSTITUTION. 39 present to liim no extraordinary appearance. So perfect, indeed, was the colour-blindness, that this most modest and simple of men, whose only pleasures were a pipe and a game of bowls, after having received the doctor's gown at Oxford, actually wore it for several days in happy unconsciousness of the effect he produced in the streets. The inventor of the calculating machine, having offered to present his Quaker friend, was evidently in a state of fussy excitement about the result of the experiment. Poor Dalton was compelled to rehearse thoroughly the ceremony of presentation by the inexorable calculator, who — having found the chances in favour of a faux- pas to preponderate — was in a dreadful " taking " on the eventful day. The calculator was completely wrong. The King addressed a few remarks to Dalton, who replied in fitting terms, and the tribulation of Babbage was over. While the claims of science were amply supplied by the genius of Dalton, Young, and Davy, literature and moral philosophy were entrusted to no ordinary hands. During the years 1804-5-6, the town-talk of London was divided between Young Eoscius, the youthful tragedian, and the lectures on moral philo- sophy delivered by the Kev. Sydney Smith, who, forty years after, said, *' I did not know a word about moral philosophy, but wanted two himdred pounds 40 SCIENTIFIC LONDON. to furnish my house. My success was prodigious." The "loudest wit I e'er was deafened with" probably exaggerated his ignorance of his subject, as he had passed five years at Edinburgh, and had opportunities of hearing Dugald Stuart and Thomas Bromi ; but in any case the lectures were a certain success in the hands of the eloquent preacher, who, if himself knowing little about moral philosophy, addressed an audience which knew nothing at all. Of very different calibre were the lectures on poetry delivered by Cole- ridge. It will be recollected that it was in these famous discourses that the author of " Christabel " promulgated those views which have since spread far and wide, and will probably hold their ground when the ephemeral opponents of Shakspeare, and worshippers of a second-rate poet like Schiller, have for long ages been consigned to oblivion. On the retirement of Davy, in 1813, William Thomas Brand, a distinguished chemist and Copley medallist, was nominated to the chair, which he so admirably filled for forty years. Meanwhile, a young man whose achievements were destined to invest the Eoyal Insti- tution with peculiar glory had, in a manner of speak- ing, received the mantle of Davy. Michael Faraday was born at Newington Butts, of poor parents. His father was a farrier, of whom — to the great sorrow of Professor Tyndall — his son could never call to mind a THE KOYAL INSTITUTION. 41 single trait of intelligence. The boy was apprenticed to a bookbinder, but in his leisure moments leamt " a little chemistry and other parts of philosophy." He had so far advanced as to construct for himself an electrical machine, when his master happened to show this specimen of ingenuity to one of his clients, Mr. Dance, who obtained permission for the apprentice bookbinder to be present at the four last lectures of Davy. The youth listened attentively, and made such notes that he was enabled to write a report of the lectm^es, which he sent to Davy, with a modest request that he might be employed in the laboratory of the Institution. Davy was struck by the clearness and exactitude of the young bookbinder, and gave him, at the commencement of 1813, the post of laboratory assistant. Towards the end of the year he accom- panied Davy abroad, as his assistant and secretary. Eeturning to London in 1815, he recommenced his duties in the laboratory of the Institution, was appointed Director of the Laboratory in 1825, and two years later became one of the regular professors of the Institution, where his scientific researches, like those of Davy, were made at the cost of the Society alone, without any assistance on the part of the State. The creed of this great philosopher, who had the glory of holding aloft among the nations the scientific 42 SCIENTIFIC LONDON. name of England for a period of forty years, is thus clearly and briefly expressed : — " I have long held an opinion, almost amountmg to conviction, in common, I believe, with many other lovers of natural know- ledge, that the various forms under which the forces of matter are made manifest have one common origin — in other words, are so directly related and mutually dependent, that they are convertible, as it were, into one another, and possess equivalents of power in their action." This is what Professor Tyndall, in his eloge of '* Faraday as a Discoverer," proclaims as the jewel contained in the famous paper " On the Magnetization of Light, and the Illumination of the Lines of Mag- netic Force." The same eloquent expositor does ample justice to the prophetic element in Faraday's intellect : — *' Faraday was more than a philosopher, and often wrought by an inspiration to be understood by sympathy alone. The prophetic element in his character occasionally coloured, and even injured (?) the utterance of the man of science ; but, subtracting that element — though you might have conferred on him intellectual symmetry — you would have destroyed his motive force." Among the many achievements of Faraday are the demonstration of the condensibility of many gases and his investigations into the reciprocal relations of heat, Hght, magnetism, and electricity. Not the least THE ROYAL INSTITUTION. 43 noble quality of this remarkable man was his marked preference of a purely scientific career over the acquirement of wealth. With the reputation acquired by the year 1832, he might have made several thousands a year by ordinary professional work, but considering all the time not actually devoted to experiment or to demonstration as a sacrifice of original investigation, Faraday lived and died poor in the world's goods. At the present day the Eoyal Institution maintains its renown — thanks to Professor Tyndall, who, by his work on "Heat Considered as a Mode of Motion," has proved himself no unworthy successor of Davy and Faraday. The late President, Sir Henry Holland, clarum et venerahile nomen, was, on his decease, replaced by the Duke of Northumberland, whose keen interest in scientific inquiry is well known. The im- portant office of Treasurer and Honorary Secretary — on which to a great extent the success of the Institution depends — is now ably filled by Mr. W. Spottiswoode. The Eoyal Institution, in addition to the attractions of its lectures, possesses a model-room, a newspaper- room, a reading-room, and a library of 36,000 volumes, presided over by Mr. Benjamin Vincent. As might be expected in a highly-fashionable insti- tution, membership is not acquired at a cheap rate, but candidates who are proposed by four members are 44 SCIENTIFIC LONDON. immediately admitted to the privileges of the Institu- tion, and pay on election ten guineas (five guineas as an admission fee and five guineas as the first annual payment). This payment secures admission to all lectures delivered in the Institution, to the libraries, and to the weekly evening meetings, with certain other privileges — such as the right of admitting two friends to the Friday evening meetings — a privilege often abused on occasions when a lion of unusual magnitude is about to roar. An inferior kind of member is the annual subscriber, who enjoys most of the privileges above named, with the exception of admission to the weekly meetings, from which sublime gatherings he is excluded. Other persons are suffered to subscribe to the afternoon lectures at the very moderate price of two guineas for all courses of lectures from Christmas to Midsummer, but are not allowed to show themselves elsewhere than in the lecture theatre, and never there on a Friday night. This weekly meeting is a wonderful combination of science and society, of physics and fashion, albeit once in a while a printer or photogra^iher manages to obtain permission to dilate on the excellence of his wares, and to thus advertise himself. Nevertheless, in spite of an occasional drawback of this kind, the Friday evening lectures are of sufficiently high class to please aU but a purely scientific audience. It is THE BOYAL INSTITUTION. 45 clear that to gratify the members — who are, after all, mere flesh and blood, and not philosophical abstrac- tions — concessions to pojDular taste and feeling must occasionally be made. Thus, while all may equally enjoy a lecture on the Acoustic Transparency and Opacity of the Atmosphere — a subject which, in its practical relation to fog- signals, is full of general interest — those of a higher and drier turn of mind experience ineffable delight when Professor Sylvester holds forth on the conversion of circular into parallel motion ; while the noble army of simple lion-hunters rush not only to hear, but to see. Sir Samuel Baker. On this particular night I find all the approaches to Albemarle Street blocked by carriages, and on making my way into the Eoyal Institution find the theatre fully occupied at a quarter-past eight o'clock, or three quarters of an hour before the time of the lecture. With the exception of a few seats reserved for the two boards of Managers and Visitors, the hall is crowded to the ceiling, every avenue being already jammed with a dense mass of people, among whom gay opera cloaks and Angot caps largely predominate over black coats and snowy shirt-fronts. A few young men are visible, but after standing about for a while and finding it impossible to approach their far friend, these youths vanish through the crowded doorway and are seen no more, thus leaving the 46 SCIENTIFIC LONDON. entire field clear to the British matron, who prevails to-night to an extent that would have struck terror into the soul of poor Nathaniel Hawthorne. There is no inconsiderable amount of crowding and pushing in this elegant throng, and I am forcibly reminded of the saying of a certain philosopher — who has seen men and cities, and the customs of them — that '' a well-dressed crowd is a rude crowd." So thoroughly and completely packed is every bench, step, and doorway, that it occurs to me as a piece of singular luck that no formidable philosophic apparatus is necessary for a dissertation on the Slave Trade of the White Nile, as the space often occupied by Professor TyndalFs tubs is packed full of chairs, to the great relief of a number of ladies. Sir Samuel Baker delivers his views on the Slave Trade to an evidently sympathetic audience, easily put into good humour by being told that England was the first na;tion to set the world the noble example of liberating her slaves — a statement, by the way, not precisely accurate, inasmuch as in 1780 was passed an Act for the gradual extinction of slavery in Pennsylvania, an example followed four years later by the States of New Jersey and Connecticut, and in 1793 the French abolished slavery in Hayti, forty years before its abolition in our West Indian Colonies. No doubt to those who had never heard much about slavery the THE ROYAL INSTITUTION. 47 remarks on its cruelty and injustice were interesting enough, but I, infelix, have had my ears too often pierced by shrill American voices, raised to shrieking pitch on this subject, during " the late trouble." Sir Samuel Baker is an excellent advocate for a new crusade against slavery, and produces ample evidence as to the atmosphere of general rascality evolved by slave-holding and slave-dealing, but his arguments, though true enough, are not very new. The lectm^er, however, possesses the excellent gift of carrying his audience along with him, and sends them home happy in the conviction that they have assisted at an anti- slavery demonstration. The claims of science are amply vindicated on the following Friday by Dr. Wright, an experimentalist of known boldness, who delivers a discourse on the *' Chemical Changes Accompanying the Smelting of Iron in the Blast-Furnace." Dr. Wright has enjoyed the advantage of pursuing his investigations in concert with Mr. Lowthian Bell, a gentleman well known by his inquiries into the chemistry of the blast-furnace, as well as by his office as President of the Iron and Steel Institute, and his gigantic enterprises in the production of iron and chemicals. Although of little interest to the general public, this lecture commands a good attendance of experts, who follow Dr. Wright very attentively through his exposition, and endure, 48 SCIENTIFIC LONDON. without a murmur, an atmosphere heavily charged with noxious gases. I have already observed that, in addition to the Friday evening meetings, where lions of the first magnitude roar by turns, several courses of afternoon lectures, in which actual teaching is combined with attractive experiments, are given during the session. These lectm^ers and their subjects attract audiences of varying strength. Looking in, one afternoon, to hear a lecture on Palaeontology by Professor Duncan, I find the theatre but thinly attended, in spite of the interesting character of the lecture and its eloquent treatment by the expositor. This apathy may perhaps be explained by the difficulty of inspiring ordinary human beings with a taste for science, pure and simple ; as I well recollect that when — at the dawn of the Darwinian system — palseontological lectures were unavoidably associated with the controversy initiated by that philosopher, every lecture directly or indirectly bearing on the theory of Development commanded a numerous and fashionable audience. Attentive listeners sought, in the discourses of Pro- fessor Owen, for facts and deductions more or less damaging to the , bold theory advanced in the now famous " Origin of Species by Natural Selection." But the uproar occasioned by the " Essays and Eeviews," and Mr. Frederic Harrison's review of the THE ROYAL INSTITUTION. 49 reviewers in the '' Westminster," has nearly subsided, and the polemical element has faded out of geological discussion. Denuded of its controversial spice, palaeon- tology no longer possesses its whilom attractiveness, and the audience of to-day is apparently composed of those who care for the subject for its own sake alone. Professor Duncan is discoursing on that friend of my youth, the ichthyosaurus, and in a few neat and graphic sentences describes the manners, customs, and peculiar structure of the great fish-lizard, with whale -like body, crocodile head, and monstrous saucer-eyes. The plesiosaur with the outline described by the late Professor Buckland as that of a *' turtle with a serpent pulled through it " next engages atten- tion, and is described very graphically as a *' long- shore-man" of the diluvial period, a prowler on the edges of the great deep, and a snapper-up of uncon- sidered trifles. Plesiosaurus disposed of, the inevitable pterodactyle turns up, the flying lizard of predatory habits, the possible progenitor of birds, and the certain original of the heraldic dragon and griffin. The shape of the head and the gradual adoption by this gruesome creature of a breast-bone give still more coherence to the theory that pterodactyle is a lizard which is rapidly making up his mind to become a bird. These particulars, and a dissertation on coral islands, make up the body of an interesting lecture, which fails, E 50 SCIENTIFIC LONDON. however, to warm the audience into enthusiasm. Perhaps people don't care for coral islands, or may- hap, to parody a line of Mr. Bret Harte — '' the ptero- dactyWs played out." On another raw afternoon, about three p.m., I betake myself to Albemarle Street, and become the s]3ectator of a widely different scene. The theatre is akeady full of eager visitors and thirsters after science, when elucidated by those brilliant experiments which excite the admiration and envy of Professor Tyndall's imitators — I had almost written rivals, forgetting that in this country, and in his own particular line of physical demonstration. Dr. John Tyndall, F.R.S., philosopher and cragsman, has no rival. At a three o'clock lecture many ladies are, of course, present, in all the variety of gorgeous array at present in fashion, for however severe may be the mental attributes of these fair students of physical science, no sternness is ever visible in their outward appearance. Pending the arrival of the professor of natural philosophy, these young ladies are chatting pleasantly among themselves. Are they talking science, I wonder, or discussing the merits of the Leonardo da Vinci hat, or the grace and style communicated by the Nor- wegian waistbelt, with all sorts of turnip watches and other quaint odds and ends dangling from it ? Do they know much about liquids and gases, or have THE ROYAL INSTITUTION. 51 they come to learn ? Verily, I know not. The well- known lecture table is covered with apparatus, and a huge bath tub occupies a considerable space. Mr. Cottrell, the laboratory assistant, is very busy, till, punctual to the stroke of three, a tall slender man, of undeniably Scottish aspect, steps to his place behind the lecture table, and a murmur of applause proclaims the satisfaction of the audience at the arrival of the successor of Faraday. The lecture, interesting in itself, is rendered doubly so by numerous and beautiful experiments, which succeed with infallible certainty. Perhaps the listeners to Professor Tyndall are accus- tomed to see his experiments '^ come off" in this way, but the traveller in search of science often sees experi- ments — chemical, physical, and others — break down with provoking perversity. No approach to anything like failure occurs to-day, and the aj^plause is great on the light- carrying power of water being demonstrated by an experiment of singular beauty. The prescribed hour ap23ears unnaturally short when the clock strikes, the lecture is closed by a short sentence, and, amid a mighty rustling of silks, the audience i^repares to depart. For a few minutes a talkative crowd blocks up the wide staircase and hall, and a sort of scramble takes place for the carriages of which Albemarle Street is full. Fashion takes its departure, and, having laid in science enough to last for a week, leaves the pro- 52 SCIENTIFIC LONDON. fessor to enjoy himself in liis admirably- appointed laboratory. As I wend my way homewards I reflect on the large amomit of good solid work that has been done in the laboratories of the Eoyal Institution during the last seventy years, and on the effect produced by the dis- semination of scientific knowledge among the upper classes. As a firm believer in the doctrine that all revolutions in taste must take their incejption above and gradually percolate through the several strata of society, I keenly sympathize with the efforts of the Eoyal Institution towards inoculating the grand monde with a love for scientific investigation. Following the example of the sun — which first illumines the moun- tain tops, and later in the day penetrates into the deeper valleys — knowledge, striking first on the upper social regions, gradually descends, until all sorts and conditions of men are irradiated by its peaceful light. ( 53 ) III. THE SOCIETY OF AETS. Like its younger sister in Albemarle Street, the Society of Arts is a notable instance of that drifting faculty which exercises so great an influence on all human institutions. Launched with widely-differing objects on the stream of events, these societies have in a certain measure displaced each other. The Eoyal Institution, now devoted to literature, and in a greater degree to pure science, was originally founded to promote those objects which have been fostered by the elder society, which, drifting away from Akt in its highest sense, has taken in hand industrial art, and applied science. One single comparison will demon- strate my meaning. In the beginning of the century — under the auspices of Count Kumford — the Koyal Institution undertook to improve the dwellings of the working classes, to warm and ventilate workhouses, hospitals, and cottages, and to exhibit and patronize 54 SCIENTIFIC LONDON. improvements in the economical consumption of fuel and the teaching of culinary science. In the present year the Society of Arts, founded originally to encourage young artists, has offered premiums for the best kinds of culinary and domestic warming apparatus, and has directly fostered attempts to instruct the people of England in the best methods of preparing food. The Society of Arts has now existed for a hundred and twenty years, and owes its foundation to Mr. William Shipley, a landscape painter, who, from a " well- grounded persuasion of the extensive utility of the art of drawing to this nation, erected the Academy in the Strand, opposite to Exeter Change." By the efforts of this gentleman a meeting was held in 1754 at Kawthmell's coffee-house, to consider the propriety of establishing a Society for the Encouragement of Arts, Manufactures, and Commerce. It was resolved to bestow premiums on a certain number of boys and girls, and an advertisement was issued accordingly. The industrial element, however, was not lost sight of, as while a number of drawing prizes were advertised, premiums were offered for the discovery of cobalt in England, the growth of madder, and the manufacture of buff leather. The primary object was the encouragement of art, but the view taken of the " polite arts " was a sufficiently THE SOCIETY OF ARTS. 55 wide one, inasmuch as the premiums offered under this head were ultimately grouped under 196 classes. Many prizes were awarded for drawing, and among the recipients was Bichard Cosway, who afterwards became a Eoyal Academician, and a portrait painter of repute. It was soon found necessary to confine the objects of study to certain models, and as no public museum or National Gallery then existed, individual collections, such as that formed by the Duke of Eich- mond, were selected for study. On the consolidation of the Society the artists of London applied for permission to hold an exhibition in the Society's rooms. This permission was granted, and exhibitions continued to be held for several years. This annual inspection of the works of rival artists, who formed themselves into separate bodies, excited emulation, directed public attention towards their works, and ultimately secured for them the royal patronage and protection. These first exhibitions of pictures by native artists in the rooms of the Society . of Arts may, therefore, be regarded as the origin of that exhibition of the Eoyal Academy which now forms one of the great events of the London season. While the encouragement of art — pure and simple — thus formed the main object of the Society, investi- gation was directed towards many practical subjects related to the central idea. Endeavours were made 56 SCIENTIFIC LONDON. to improve the materials employed by artists, and much attention was devoted to the various engraving processes as they gradually came into vogue. Wood engraving, aquatint, and mezzotint, were the subject of anxious care, as were improvements in pigments, oils, and varnishes. Bronze casting and chasing, iron castings, and artistic metal work, were also encouraged, and at a later date, when Alois Senefelder, an actor of Munich, discovered lithography, the new art was first intro- duced to this country under the auspices of the Society of Arts. Steel engraving was also first taken seriously in hand by Mr. Charles Warren, chairman of the Fine Arts Committee, who, at the suggestion of Mr. Gill, chairman of the Mechanics Committee, adopted a new method of treating steel plates. Previously to this, many attempts had been made to engrave on steel. Albert Diirer is said to have etched on steel, and there are four plates etched by this artist, impressions of which exist in the British Museum, and which in all books of art are recorded as having been executed on steel. In the attempts to revive this art, pieces of saw-blades were selected as the most promising material, but these efforts were attended with very little success. A Mr. Eaimbach then endeavoured to engrave on blocks of steel, but without achieving any material advance. Mr. Gill now drew the attention THE SOCIETY OF AETS. 57 of Mr. Warren to the method employed at Birming- ham in the manufacture of ornamental snuffers and other articles of cast steel. The process employed at Birmingham was *' to subject the steel, after having been rolled into sheets, to the process of decarboniza- tion, by means of which it is converted to a very pure soft iron, being then made into the required instru- ment or other article. The ornamental work is engraved or impressed on the soft metallic surface, which, by cementation with proper materials, is again converted suj)erficially into steel. Mr. Warren modified this process, and obtained thin plates of steel capable of being acted upon by acids and cut with the graver, without destroying the cutting edge of the tool — as was the case with the saw-blades. The resulting plate yielded a greatly increased number of impressions." When brought to perfec- tion, steel plates were found equal to the production of ten or twelve times the number of impressions yielded by copper plates. Capital was invested in the production of works of a high class, with the effect of spreading far and wide through the country myriads of prints calculated to elevate and improve the taste of the people. This process of conversion and recon- version of steel was soon afterwards applied by Perkins to the production of steel rollers. These were first softened and then pressed into the engraved surface of 58 SCIENTIFIC LONDON. a hardened steel block, and having acquired a design in relief were themselves hardened in their turn, and by being applied to softened steel plates produced almost indefinite multiplication of the original en- graved plate. For commercial purposes this inven- tion proved of immense value in the production of bank notes, receipts, and postage stamps. To ignore the exertions of the Society of Arts in the direction of agriculture, and especially arboriculture, would be to omit an important page in its history. The introduction of new varieties of grasses and roots was sedulously encouraged, while drill ploughs, the drainage of land, root slicers, chaff cutters, scarifiers, reaping machines, threshing machines, and means of harvesting hay and corn in wet seasons, were all subjects of premiums. Big things and little things came in for their share of attention. In the early days of the Society sheep were marked with tar, to the great loss of wool-growers. The Society sought strenuously to modify and improve the mode of marking sheep, and meanwhile instituted a crusade against that bold invader, the Norway rat, who had recently overrun the country. The preservation of timber was an object of earnest solicitude. In this age, when coal has effectually displaced wood as a heat producer, and iron has been successfully applied to the construction of houses and THE SOCIETY OF ARTS. 59 ships, it is difficult to realize the anxiety of our fore- fathers at seeing whole forests destroyed for smelting purposes. For a long time past the work of destruction had been going on, when the Society of Arts stepped in to advocate the planting of trees on a large scale. The production of oak was a special object of the Society's attention, the planting of acorns was carried on to a very large extent, and gold medals for raising that description of timber were awarded to many noblemen and gentlemen, among whom were the Earl of Wilton, the Marquis of Tichfield, Mr. Morse, Mr. Curwen, and others. The cultivation of the ash — for which the Bishop of Llandaff received a gold medal — of the Scotch fir and larch, and of fruit trees generally, received active encouragement. Under the auspices of the Society millions of trees were planted, to the enrichment and adornment of many previously barren slopes. It is worthy of remark that to a neglect of these precautions is assigned an actual change of the climatic conditions of parts of Italy, and that the reduction of the Arno to an insignificant stream is ascribed to the reckless denudation of the mountains among which that historic river takes its rise. Travellers in Switzerland also have not failed to observe in the side valleys many relics of ancient mines, deserted, at last, because all the wood within carrying distance had been recklessly destroyed 60 SCIENTIFIC LONDON. without any attempt being made to replace it by planting. Considerable effort was devoted to encouraging the introduction and culture of spices into the British possessions. The cinnamon tree was introduced into Jamaica ; the nutmeg plant into St. Vincent ; the clove tree into Trinidad; the mango and the bread- fruit tree were also planted in the West Indies. Attention was also directed towards such imports as were capable of discovery, manufacture, and culture at home. Cobalt was discovered in Cornwall ; buff leather and its manufacture improved ; copper and brass vessels were tinned ; and hemp, flax, and madder were cultivated for the use of our manufacturers. " Saw- mills were built ; our fish supply improved ; and the curing of fish encouraged. Upon the fish trade alone the Society expended many thousands of pounds, and succeeded in establishing a regular supply to the London markets." During the greater part of its career the Society thus addressed itself to the task of fostering the useful arts. One condition, however, was, in the early days of the Society, rigidly insisted upon. The inventor who sought to obtain recognition of his discovery was obliged to forego the idea of patenting his work. What was given to the world by the assistance of the Society THE SOCIETY OF ARTS. 61 of Arts, was to be given freely and openly for the benefit of all. Although this principle would find many and eloquent advocates at the present day, a period intervened during which it was found necessary to make concessions to patentees. The introduction of steam as a motive power led to a sudden and immense development of mechanical ingenuity, and swelled the prospective reward of a successful inventor to such large proportions that it was no longer probable that men would work for honour and glory alone. Eventually patentees were permitted to read papers before the Society of Arts, which, dmdng the greater part of a century, continued to take an active interest in advancing the interests of science, and in affording aid and countenance to the other societies of less catholic tendencies, which sprang rapidly into existence. As has been already pointed out, the Koyal Academy in its youth owed much to the Society of Arts ; and it is worthy of note that, not only was the first exliibition of the works of rival artists held in the Society's rooms, but the first collection of photographs exhibited there in 1853. The Society still maintains a liberal tone, and is generous enough to grant the use of its handsome room to many societies for the purpose of holding their various meetings. If the Society in the Adelphi merit a place of honour as a promoter of other societies, still more does it 62 SCIENTIFIC LONDON. demand notice as the mother of exhibitions. Its exhibitional maternity was shown in this wise. In the year 1841 the Society of Arts, like many other originally active bodies, had shown signs of falling into decrepitude. For many of the purposes for which it was originally established its office had been filled by other institutions, which, being less expansive in their views, appeared likely to act towards the mother society like young ducks hatched by a barn-door hen, and take to the stream of the future without consult- ing the feelings of their foster-parent. The Society was obviously falling into the sere and yellow leaf, and it was clear that something had to be done to rejuvenate it. A committee was appointed to revise the working of the Society, and that body recommended that a Council to manage the affairs of the Society should be instituted. The committee in its report also gave expression to the conviction " that the Society cannot continue to exist on the plan of j)ro- ceeding which is at present pursued," and that "the object of the Society is the promotion of the useful arts rather than the personal gratification of the members." It was further recommended that six commitees should be established, of five members each, and many other valuable pieces of advice were tendered, but nothing came of all this for the time being. At length, however, measures were taken for THE SOCIETY OF ARTS. 63 obtaining a Eoyal Charter of Incorporation, finally granted in 1847, and in the mean time it was proposed that an Exhibition of English Industry, analogous to those held abroad, should be instituted. The first action taken in this direction was an offer of special prizes for articles of manufacture, and a special fund was obtained for this purpose by private subscription. It was deemed necessary to stimulate the makers of English pottery to efforts towards an artistic com- bination of form and colour. A committee of artists was appointed to adjudge the prize for a tea-service, and this was awarded to a set designed by " Felix Summerly," and manufactured by Messrs. Minton. The identity of '* Felix Summerly" was then disclosed, and the Society's silver medal was presented to Mr. Henry Cole (who has since received the Companion- ship of the Bath), on the 12th of June, 1846. From this date a notable change came over the constitution of the Society. Yearly exhibitions were held. It is true that these were of a sectional character, and only proposed to illustrate certain branches of English industry; but it is not the less true that they were the immediate precursors of the Great Exhibition of 1851. Prizes for modern industrial art were offered, and were eagerly competed for. Manufactures and artistic productions were got together at great ex- penditm-e of cash and industry, with the effect of 64 SCIENTIFIC LONDON. rapidly increasing the number of members. In 1847, the members of the Society numbered scarce five hundred ; but within three years these numbers had tripled. But, in 1849, there were " croakers " in the camp. Not a few of the ruling spirits were inclined to '' look back from the plough." As an instance of this may be quoted a recommendation of the Finance Committee of 1849, that " the exhibitions be discontinued," and another, passed in December of the same year, that "it is expedient to reconsider the policy of an Art Manufacture Exhibition in the year 1850." But the advanced spirits of the Society were not to be baulked. Against the council of the ancients a formidable opposition was organized. Mr. Cole resigned his seat on the Council, and, biding his time till the general meeting, effected a noteworthy cou]^ d'etat. On election day the reactionary party were ousted by an immense majority, and an entirely new Council elected. The Exhibition of Ancient and Mediaeval Art was duly held, and resulted in a splendid success, and a complete revolution of the financial condition of the association. In 1850 the debts of the Society amounted to ^2402, an amount that was reduced in 1851 to 5S1696, since when the Society has become not only solvent, but possessed of a large accumulation of capital, which — in the opinion of many of the members, now amounting to over 3000 — THE SOCIETY OF AKTS. 65 it is somewhat chary in dispensing. This great storm, which completely altered the condition of the Society of Arts, and culminated in the Great Exhibition of 1851, can thus be distinctly traced to Mr. Felix Summerly's ^' tea-cup." The merit of initiating the idea of an International Exhibition has been often warmly contested, but there is no longer any doubt that the original proposition was made to the Committee of the Society of Arts in 1844, by Sir William Eothergill Cooke. There is no question that the idea of this gentleman was clearly that of an International Exhibition, at that time declined by the Committee of the Society of Arts, but at a later period adopted by that body with the sanction and co-operation of the late Prince Consort. In the month of June, 1849, the secretary, Mr. J. Scott Eussell, stated at the annual meeting, in the presence of the late Prince Consort, that, owing to the yearly increasing success of the Society's Exhibition, the Council had no doubt of their being able to carry out the plan originally proposed for holding a great national exhibition of the products of British industry in 1851. This statement led to frequent communica- tions between His Eoyal Highness the president, and various members, with the ultimate result of expand- ing the plan to international dimensions. The Prince Consort, as president of the Society, brought the DO SCIENTIFIC LONDON. scheme officially under the notice of the Government ; but in the mean while the Society of Arts was not idle, and had already entered into a contract for building a convenient edifice, when a royal commission was issued. Mr. Scott Eussell and Mr.— now Sir — Stafford Northcote were appointed secretaries. An executive committee was formed, consisting of "Henry Cole, Charles Wentworth Dilke the younger, George Drew, Francis Fuller, and Eobert Stephenson, with Matthew Digby Wyatt as secretary." Meanwhile the Society of Arts had organized the financial arrange- ments necessary for carrying out the scheme, but the immediate connection of the Society with the Exhibi- tion now came to an end ; the child had outgrown its nurse, and required nothing short of a royal commis- sion to manage it. How well the Exhibition of 1851 was managed, and how after the final adjustment of accounts a surplus of ^186,438 18s. 6tZ. remained in hand, are now matters of history, as well as the expenditure of that sum as part of the money devoted to the purchase and development of the Gore House estate. Since the launching of the Great Exhibition, the Society of Arts has done much good work in promoting industrial art and encouraging inventive genius. It is true that much of its work has been taken out of its hands by the societies and museums to which it has THE SOCIETY OF ARTS. 67 given rise. Among these is the PhotograjDhic Society, whose inception was due to the exhibition organized by Dr. Diamond. The South Kensington Museum itself may be fairly regarded as an offshoot of the Mediaeval Exhibition, while the Government Department of Science and Art is dii'ectly descended from the parent body. But the mission of the Society is not to repose on its laurels. It comes to the fore with a formidable list of premiums, at the head of which is a series of gold medals and prizes of ^50 for improved cooking and warming apparatus; ^6500 are devoted to this purpose, and have been placed at the disposal of the Society by a single member. A large number of prizes in money, and many gold and silver medals, are also offered to inventors. Much interest is excited at the present moment concerning the award of the Albert Gold Medal, a prize established in memory of the late Prince Consort, to reward " distinguished merit in promoting arts, manufactm-es, or commerce." This medal was first presented in 1864 to Sir Eowland Hill, K.C.B., in 1865 to the late Emperor of the French, and in 1866 to Faraday. Since then, this distinguish- ing mark of the Society's appreciation has been con- ferred on Wheatstone, Whitworth, Liebig, Henry Cole, Henry Bessemer, and has this year been awarded by the council to Dr. C. W. Siemens, " for his researches in connection with the laws of heat, and the practical 68 SCIENTIFIC LONDON. applications of them to furnaces used in the arts ; and for his improvements in the manufacture of iron ; and generally for the services rendered by him in connection with economization of fuel in its various applications to manufactures and the arts." For some years the Society's examinations, con- ducted through local institutions about the country, have assisted the spread of general education, and now that this work is being more completely executed by the University local examinations, the Society has set on foot a scheme of technological examinations, which it is hoped may bear good fruit. The members of the Society are supplied with ample entertainment by the ordinary meetings, the lectm^es endowed by Dr. Cantor, and the meetings of the African, Indian, and chemical sections. For the very moderate sum of two guineas per annum they are allowed to attend meetings, to introduce two visitors, and moreover to receive a copy of the weekly journal published by the Society. Prior to 1852, no Journal of the Society of Arts existed, the Society being content with a somewhat meagre volume of Transactions. With the new era of prosperity the Journal was hap- pily inaugurated, and now supplies members of the Society with a complete record of the weekly proceed- ings, together with such admixture of general scientific or technical matter as may be deemed necessary by THE SOCIETY OF ARTS. 69 the editor, Mr. H. T. Wood. With the growth of the Society its organ has, of course, increased in import- ance, and during the last year or two, especially, has been considerably improved. Not the least valuable part of the Journal is the preservation of the discus- sions which generally ensue on the reading of a paper, and occasionally exceed in importance the paper itself. In the course of my travels I have had many opportunities of enjoying the discussions at John Street, Adelphi. Just before entering the spacious and handsome " great room," adorned by Barry's well-kno^Ti pictures, I find a notice that any gentle- man wishing to take part in the discussion should make his name known to the secretary, Mr. P. Le Neve Foster. This notice has always appeared to me as a sort of '' fiery cross," or summons to immediate action, calling upon me then and there to "pull my- self together," collect my scattered wits, and hold myself in readiness to jump up at the right moment and contradict everybody. As a rule, I succeed in crushing this feeling, and follow my general plan of retiring into myself, and waiting until called for ; but there are moments when my amazement at finding that I understand the subject overcomes my natural timidity, and I say, " Ha ! ha ! " among the captains. Inasmuch as the ordinary meetings are understood 70 SCIENTIFIC LONDON. to be held for the exjDress ]3iirpose of ventilating new ideas or pet crotchets, it is only natural to suppose that the fun of these meetings exists in the discussion. To those of an unregenerate nature there is always something objectionable in being talked to, or talked at, without a chance of reply. There is no man whom I love and revere more than my friend the Eev. Mr. Chasuble. He is a good classic and a good fellow, generous and hearty, a good logician, and a worthy gentleman, whom I love everywhere but in the pulpit, where he has it all his own way. I admire Professor Stillmore immensely, and love to hear him discourse excellent science, except on those occasions when he appears behind the lecture-table as another and very inferior being to the real Stillmore, whom I delight to cultivate. Holding these heathenish views, and loving not to sit at the feet of any Gamaliel whatsoever, I enjoy myself hugely at the Society of Arts. I know that, so soon as the lecture is announced, somebody will make up his mind to come down and contradict all the statements advanced. No sooner does the victim appear at the reading-desk than I glance round the room, and often succeed in detecting those who come to argue — if not *' to scoff." These critics know all about the subject, whether it be Frozen Beef or a Channel Tunnel. They become feverish if the reader of the paper be slow or at all inarticulate, and they THE SOCIETY OF AETS. 71 look keenly at his diagrams, meaning to make short work of those productions in due season. For his allotted space the reader is suffered to proceed without let or hindrance ; but no sooner has he made an end of his reading, than well-informed gentlemen — who have either been listening attentively or, as is more probable, been thinking over what they should say when he had done — spring up and proceed to demolish him bit by bit. After a while, a reaction sets in, the friends of the lecturer support him more or less warmly — generally less — and the battle becomes general all along the line. The hero of the evening has the right of reply, so that the much-valued privi- lege of the last word rests with him. Under these regulations, there is often much healthy talk, and occasionally some good "tossing and goring" — a quotation which reminds me that its author was one of the early debaters of the Adelphi, and that a " subject relating to mechanics " was once descanted upon at the Society of Arts and Manufactures, with a "propriety, perspicuity, and energy which excited general admiration," by no less a personage than Dr. Samuel Johnson. 72 SCIENTIFIC LONDON. IV. THE INSTITUTION OF CIVIL ENGINEEES. Whatever diverse opinions may be held as to the stationary or progressive nature of the moral sciences, and although art may be said to have actually retro- graded since the age of Pericles, no doubt can exist as to the enormous advance in wealth and comfort made by the civilized world during this present century — emphatically the century of the straight line. It is probable that an ancient Athenian gentleman was at least as weU instructed in metaphysical science as a modern graduate of Oxford or Edinburgh, Heidelberg or Halle. So far as keen artistic sense and purity of taste are concerned, the Greek — with eye educated by the constant contemplation of forms of perfect beauty — with ear attuned to the sounding march of Homer's hexameters, and with mind accustomed to dwell on the stern grandeur of ^schylus, the polished lines of Sophocles, and the more sympathetic verse of Euri- THE INSTITUTION OF CIVIL ENGINEERS. 73 pides — possessed an unquestionable advantage over the modern scholar, whose attentive i^erusal of novels and newspapers is hardly calculated to improve his oratory. If, however, it may be conceded that no advance has been made — nay, more, that actual retrogression has taken place — during the last 2500 years in the study of words and their uses, and in the production of beautiful forms, it must, on the other hand, be admitted that the modern Englishman pos- sesses a knowledge of things and wields a power over the forces of nature undreamt of by the poets, philo- sophers, and grammarians who discoursed sweetly in the garden, or thundered out sonorous periods in the Agora. Most worthy of note is the marvellously short space of time in which the great modern development of human power has taken place. Albeit a hardy plant, science has grown with almost incon- ceivable rapidity. In some five or six thousand years man had only improved the canoe and the coracle into a gaUey and a sailing ship, and had shown even less inventive genius in the methods of terrestrial locomotion — indeed, so far as roads were concerned, England was worse off 200 years ago than during the period of the Eoman occupation. Something had been done in widening the minds of men by making them better acquainted with the globe that they inhabited. Vasco de Gama and Columbus had 74 SCIENTIFIC LONDON. unlocked the treasures of the Eastern and Western World ; the mariners' compass had come into general use ; Copernicus, Tycho Brahe, and Galileo had made short work of traditional cosmogonies, and those potent civilizers, the printing-press and gunpowder, had been invented. But the material condition of mankind had as yet received no immediate benefit from these discoveries. The wealth of Mexico and Peru, far from enriching Spain, had diverted from the parent country the energy of her bravest sons, and the loss of the Low Countries had inflicted on the State a loss from which she has never since recovered. France was occupied in the pursuit of glory; Holland, rich and prosperous beyond all European nations, was harassed with the task of Joshua — in staying the sun of Louis Quatorze ; while England had as yet given but small promise of the industrial pre-eminence she was destined ultimately to assume. Nevertheless indications were not wanting in our little island of a strong desire for material progess, due, according to some authorities, to the great awakening of the human mind during the period of the Eenaissance, and according to others to the inductive system of philo- sophy propoimded by Bacon. Be this as it may, an inquiring spirit was abroad, and investigations into the then hidden forces of nature — with the direct intention of pressing them into the service of mankind THE INSTITUTION OF CIVIL ENGINEERS. 75 — occupied the miads of many eminent Englishmen. Bobert Boyle rendered important services to science, and hovered on the brink of other yet more important discoveries. Newton, Flamsteed, and Halley immor- talized themselves by their contributions to astronomy; but most remarkable of all were the sudden strides made in the arts of construction, in which the cele- brated Hooke greatly distinguished himself. Leuwen- hoeck raised the microscope to the dignity of a scientific instrument, under Savery the first crude steam-engine was brought into working order and employed as an ef&cient agent for raising water, and Newton invented the reflecting telescope. So far as the sudden advance in mechanical science which signalized the last century can be assigned to any one IDerson it may be ascribed to this great man, whose " Principia " revealed the method of applying mathe- matical princix^les to the forces of nature. All this admirable seed, destined to bear fruit an hundred and a thousand fold in due season, did not of course produce any immediate amelioration in the condition of the British nation. More than any other nation England might, as late as a hundred and fifty years ago, have been pronounced singularly deficient in public works. While Holland — and for that matter India and China — possessed a vast system of canals, the internal communications of this country were in a 76 SCIENTIFIC LONDON. barbarous condition. Artificial harbours, canals, and machinery there were none, and the public roads across the country were for the most part little better than bridle paths. Over these primitive and deeply- rutted tracks, often impassable in wet weather, the few wheeled carriages in use were dragged, at a fearful expenditure of sinew, time, and temper. A county magnate, on the occasion of one of his rare visits to London, set his affairs in order before start- ing, and packing a lumbering coach with ample pro- vision, trusted to the strength of six or eight powerful Flanders horses to drag him through the tedious miles of mire which separated him from the metropolis, holding himself fortunate indeed if he escaped break- ing down more than half-a-dozen times on the road, and eluded the attentions of professional or amateur highwaymen. So long as the roads remained mere muddy tracks it was found convenient to avoid as much as possible the use of wheeled carriages. The " solitary horseman " and the ''two travellers," beloved of romancists, picked their way among the stones and quagmires which separated one great town from another, and the commerce of the country was mainly carried on by means of pack-horses. Owing to the difficulty and danger of transit, the luxuries of life were exorbitantly dear, and even those necessaries which did not happen to grow in the im- THE INSTITUTION OF CIVIL ENGINEEES. 77 mediate vicinity of the consumer were difficult of attainment. In the total absence of canals, inland navigation was both tedious and uncertain. " The rivers were left," as the Eastern potentate remarked, *' as Allah had made them ; " and therefore this imperfect river navigation could only be undertaken under favourable circumstances, i.e. when the rivers were sufficiently flooded. In a few rare instances temporary flush-weirs were used to pen up the water in shallow places, and in a few others side cuts with the pound lock were introduced, with side weirs con- structed with the double object of allowing the floods to escape and utilizmg the water-power. During the first quarter of the last century New- comen's steam-engine, having been improved by Potter and Beighton so as to become self-acting, was used for pumping water from collieries, but the con- sumption of fuel was so great that its application continued to be very limited. For driving such machinery as existed, and for working the few mills in operation, wind and water were the sole motive powers employed, and with the exception of the silk mills at Derby, introduced by Sir Thomas Lombe from Italy, nothing in the shape of manufacturing machinery was known. Metallurgy was yet in its infancy — charcoal being the chief medium used for reducing iron — sanitary precautions were unknown — 78 SCIENTIFIC LONDON. the magnificent cloaca of Eome having found no mediaeval successors — paving was neglected, and gas as yet undreamt of. A great change was at hand. A revolution in the face of England was about to be wrought by three remarkable men — the fathers of modern scientific engineering. In 1716 James Brindley was born at Chapel-en-le-Frith, in Derbyshire. Eight years later John Smeaton was born at Austhorpe, near Leeds ; and in 1736 James Watt saw the light at Greenock. If strict definition be adhered to, Watt can hardly be classed as a civil engineer, although he proposed a plan for improving the river Clyde, and suggested the idea of the Caledonian Canal, before devoting himself exclusively to the improvement of the steam-engine, and working out those grand discoveries which have immortalized his name. Although born later than Brindley, Smeaton was the first to distinguish himself — a circumstance attri- butable probably to the comparative ease of his circum- stances, and from his having no educational leeway to make up in manhood. Commencing with a fair education, and devoting himself for a short space to the study of the law, Smeaton soon discovered that the bent of his genius was in another direction, and being luckily not thwarted by his parents, applied his vigorous mind to philosophical inquiry. Starting in THE INSTITUTION OF CIVIL ENGINEERS. 79 life as a mathematical instrument maker in 1750, he two years later attracted the notice of the scientific world by his air-pump, and subsequently, by several communications to the Eoyal Society on mechanical subjects, so raised himself in the estimation of that learned body as to obtain their gold medal, and the honour of being elected a Fellow of the Society. The celebrated paper on the natural powers of wind and water to turn mills and other machinery depending on circular motion produced directly and indirectly the most important results. Owners of water-power discovered that their power was increased one-third by the adoption of Smeaton's plan. Subsequent improvements were made on Smeaton's system for windmills, which by Meikle, By water, and Cubitt were brought — as were high-roads and mail coaches — to absolute perfection just as they were about to be thrust from the world by steam. Smeaton next devoted his attention to the laws which govern the formation and the maintenance of harbours, and, after inspecting the great works in operation in Holland, introduced many improvements in the draining of marsh lands. About the middle of the last century a perfect rage sprung up for public works, and, in the conduct of these, Smeaton never once failed. Curiously enough, his first important work is that with which he is most im- 80 SCIENTIFIC LONDON. mediately identified. At the very period — 1755-59 — when he was unknown and untried as a practical engineer, he was selected as the fittest person to he entrusted with the rehuilding of the Eddy stone Light- house, just destroyed by fire. By the design and construction of this celebrated edifice, Smeaton intro- duced a new era in masonry, and achieved one of the greatest triumphs that have ever fallen to the lot of an engineer. While Smeaton was battling with the winds and waves, Brindley was struggling with the difficulties of emerging from an agricultural to a mechanical career. Born of humble — but as the American humourist hath it, " not otherwise dishonest " — parents, Brindley was, almost until manhood, entirely without educa- tion. Drifting afterwards into the millwright's trade, he acquired by his mechanical skill a certain pro- vincial celebrity which, although not very lucrative in itself, yet paved the way to an engagement destined to immortalize Brindley and enrich his patron. An- terior to the career of Brindley, pound locks had been introduced on river navigations, and were also used on the Sankey Canal in 1755. This work was effected by making an almost entirely new channel, and its success gave a remarkable impetus to canal construction. In 1758 Brindley was called upon by the Duke of Bridgewater to advise on his project of THE INSTITUTION OF CIVIL ENGINEERS. 81 a canal from Worsley to Manchester. Without un- necessary pondering or hesitation, Brindley forsook tradition, and, striking into a new path, placed the inland navigation of England far in advance of what had been achieved elsewhere. He constructed — in addition to the Bridgewater Canal, with its many miles of underground commu- nications in the Worsley coal mines, and its famous aqueduct at Barton — the celebrated Grand Trunk navigation, cutting through the mountainous back- bone of England by the Harecastle tunnel. In con- junction with Smeaton and others he estabhshed water communication between the distant and appa- rently naturally divided towns of London, Liverpool, Bristol, and Hull, and justly acquired the title of father of inland navigation. While Brindley and Smeaton were engaged in the construction of great public works, James Watt was giving up the best years of his life to the improve- ment of the steam-engine. Stated briefly, the inven- tions of Watt, which had the effect of bringing the steam-engine into general use, were as follows : the separate condensing vessel, with an air-pump for exhausting the steam cylinder, instead of injecting cold water into it for impelling the piston on New- comen's plan by atmospheric pressure. In conjunc- tion with Boulton, Watt brought these improvements G 82 SCIENTIFIC LONDON. into operation about the year 1773, and produced a greater diminution in the consumption of fuel than Smeaton, who had rendered the system of Newcomen as perfect as it could be made, had already done. The labour of the eight succeeding years resulted in the invention of rotatory motion by the steam-engine, first by the crank, and afterwards by the sun and planet wheel, thus adapting it to the driving of all kinds of machinery. A year later, Watt invented the application of steam with expansion and with double action, alternately above and below the piston, and in 1784 invented the parallel motion, or working gear and valves and the governor. These improve- ments being carried into effect in the engines made by Boulton and Watt in 1784-85 induced their intro- duction to mills, whence they have succeeded in expelling simpler applications of natural forces. Concurrently with the advance made in the con- struction of harbours, lighthouses, canals, drainage works, and the steam-engine, great improvements were effected in the roads of the country. Food for melancholy reflection is supplied by the fact that many of the most important roads in the world have been made for purely military purposes — i.e., to bear soldiers to kill people, not corn to feed them. The ancient Koman roads — admirably constructed as they were — owed their construction to strategic purposes, THE INSTITUTION OF CIVIL ENGINEERS. 83 and the famous road over the Simplon was made with no other object but to facilitate the pouring of a French army into the plains of Lombardy. For like reasons a certain impetus was given to road- making in England by the raids of the two Pre- tenders ; and by the direction of General Wade the first really good roads seen in this island since the decadence of the Komans were formed through the north of England into the Highlands. These works, constructed by military engineers, drew strong atten- tion to the wretched condition of the ordinary roads of the country, which, as has been previously re- marked, were simply worn tracks and nothing more. It is true that public or hackney coaches were estab- lished in London in 1625, but it was not until 1666 that a coach was established which travelled between London and Oxford in two days. Another, called the " Flying Coach," was afterwards started to perform the journey in thirteen successive hours — or at the rate of four miles an hour — but this unprecedented feat could only be accomplished during the summer months. In 1712 London and Edinburgh were con- nected by a service of coaches, but this journey occu- pied thirteen days, exactly the period required by the Great Western to perform her first voyage from Bristol to New York. Improvements in the con- struction of roads and of coaches were gradually 84 SCIENTIFIC LONDON. introduced, and in 1784 passengers and letters were conveyed from London to Edinburgh in three days and nights, an achievement which created the most extraordinary excitement. This period was next reduced to forty-two hours, when the ultimate effect of animal spirit and endurance was reached. The transport of goods was enormously expensive and tedious. It required from two to three days to convey a ton of merchandise from Liverpool to Man- chester, at a cost of forty shillings per ton, a service now performed in two or three hours for as many shillings. In the construction of the improved high-roads which covered this island during the early part of the present century, a prominent part was taken by Thomas Telford, who, in conjunction with William Jessop and John Eennie, composed a trio of emi- nent engineers — the connecting link between the . fathers of the craft and the generation of workers ! who, in our own day, have covered the globe with evidences of their skill. The labours of Jessop — the pupil, and afterwards the assistant, of Smeaton — reflected no discredit on his great teacher. Among the many great undertakings that he conducted to a successful conclusion may be mentioned the im- provements on the rivers Aire, Calder, and Trent, the Grand Junction Canal, the inland navigation of THE INSTITUTION OF CIVIL ENGINEERS. 85 Ireland, the City ship-canal across the Isle of Dogs, and the conversion of that part of the river Avon which flows through the city of Bristol into an im- mense floating dock. Jessop was, moreover, the con- sulting engineer of the West India Dock Company in London, and of the Ellismere Canal Company. He also laid down the Surrey iron rail, or tramway, which, albeit a failure as a speculation, is worthy of note m a sketch of the progress of civil engineering as one of the earliest applications of this mode of conveyance to the purposes of public traffic. John Eennie — whose name looms large in the annals of engineering — enjoyed the advantage of early training under the ingenious Meikle, the in- ventor of the threshing machine, and worked as an occasional student under some of the most celebrated professors of the University of Edinburgh. Com- mencing business as a millwright, in his native county of Haddingtonshire, he was soon led to change the scene of his labours in consequence of an introduction to James Watt, who invited him to superintend the erection of the Albion flour-mills, where the perfected machinery of Boulton and Watt was to be put into operation. Quickly acquiring reputation as a superior mechanist, he was appointed about the year 1791 or 1792 to direct the execution of the Lancaster Canal. This and the Crinan Canal, 86 SCIENTIFIC LONDON. which divides the Mull of Cantire from Argyleshire, established his reputation as a civil engineer of the first rank. He was associated with other great works — the completion of the Eau Brink cut, and the new Nene outfall for the drainage of the fens of Norfolk, Lincoln, and Cambridgeshire. He also participated in the construction of three of the large dock estab- lishments in the port of London, the Leith docks, and extensive additions to those of Liverpool and Hull. Still more stupendous operations now engaged his attention. Sheerness Dockyard was raised by him out of a quicksand 25 feet deep and 10 feet under low water. Pembroke was also designed by him, as were the breakwater in Plymouth Sound, the artificial harbours of Kingstown, Howth, Holy- head, and Donaghadee, together with three bridges over the Thames, and others in various parts of the country. Thomas Telford — a Dumfriesshire man — enjoyed none of the advantages possessed by Eennie and Jessop, but advanced to a high position by the sheer force of that pe7fervidum ingenium with which the inhabitants of North Britain are supposed to be endowed. A native of Eskdale, he received the educa- tion commonly given to the peasantry of that country, and having been apprenticed to a stonemason, worked diligently at his trade mitil his twenty-third year. A THE INSTITUTION OF CIVIL ENGINEERS. 87 visit to Eclinburgii revealed to him a wider horizon than that of his native valley. Coming to London, and working for a time as a mason in the quadrangle of Somerset House — then building — he attracted attention by his superior intelligence, and was appointed to superintend the erection of a new official residence in Portsmouth Dockyard, and subsequently undertook the direction of some alterations in Shrews- bury Castle. In 1793 he was nominated acting engineer of the Ellesmere Canal. Albeit every part of England contains some record of Telford, his works were not confined to the United Kingdom ; his skill was employed in the construction of the great ship-canal of Gota, in Sweden, the last connecting link in the navigation from the Baltic Sea to the German Ocean. The Caledonian Canal, originally proposed by Watt, and advised on by Jessop, was executed by Telford. Participating in the construction of many other great works — notably the Gloucester and Berkeley ship-canal — Telford is, perhaps, after all, best known by the gigantic system of roads exe- cuted under his superintendence — the Highland, the Holyhead, and the Glasgow and Carlisle, whereby '* whole regions were brought within the pale of society." Besides the thousands of minor bridges forming part of these works, Telford constructed several bridges over the Severn, the Broomielaw 0« SCIENTIFIC LONDON. bridge over the Clyde, the bridge over the Conway, and, lastly, the famous structure which spanned the Menai Straits. Telford closed a long and glorious career in 1834, and found a fitting tomb in West- minster Abbey, having lived to see the advent of the iron roads that were destined to consign to disuse many of the finest products of his genius. The great development of civil engineering pro- duced by the labours of himself and his contempo- raries induced the illustrious Smeaton, so early as 1771, to found the society since known by his name. At that period the Eoyal Society absorbed nearly all those distinguished by scientific attainments. In the comparative infancy of scientific knowledge this was natural and possible from the very catholicity of that illustrious body, but as the objects of philosophical research multiplied, and the sphere of inquiry widened, many offshoots from the parent stem assumed an independent existence. The Eoyal Astronomical Society was the first of these, and was followed by associations for promoting the study of geology, botany, zoology, geography, and statistics. The Smea- tonian Society of Civil Engineers had existed for nearly fifty years, when it was felt that the growing importance of civil engineering demanded an institu- tion on a larger scale. Thomas Telford (himself a Smeatonian) concurred in this view, and an oppor- THE INSTITUTION OF CIVIL ENGINEERS. 89 tunity was soon found of carrying it into effect; Towards the end of 1817 a few gentlemen, then begin- ning life, resolved to form themselves into a society for promoting a regular intercourse between those engaged in the various branches of civil engineering, and *' thereby mutually benefiting by the interchange of individual observation and experience." The first meeting was held at the King's Head Tavern, in Cheapside, on the 2nd January following, when rules were adopted for the government of the society, which continued to assemble for the next two years, when it was resolved "that a respectful communication be made to Thomas Telford, Esquire, civil engineer, to patronise the institution by taking upon himself the office of President." Telford accepted the chair with- out hesitation, and was formally installed on the 21st March following. Keceiving a new impetus from this important accession of strength, the institution grew rapidly in importance, until on the 3rd of June, 1828, it received a charter of incorporation under the Great Seal by the title of the " Institution of Civil Engineers." During the quarter of a century which elapsed between the formation of the Society and the occupa- tion of the presidential chair by Sir John Eennie in 1846, the ci^dl engineers of the United Kingdom had distinguished themselves not only at home, but in 90 SCIENTIFIC LONDON. every quarter of the globe. Steam had asserted its empire on land and sea. Time and space had been reduced to their lowest terms. Projects for traversing water by boats worked by mechanical means appear to have occupied the attention of philosophers from remote periods — remote, that is, from an engineering point of view. The propulsion of boats by wheels is said to date as far back as the time of the Eomans, and the Chinese are said to possess a boat moved by these means. Spain also puts in a claim on behalf of one Blasco de Garay, reported to have made an experiment in propelling vessels in the presence of the Emperor Charles V., at Barcelona, in 1543. Kevert- ing to more exact history, we find Prince Eupert owning a barge propelled by wheels in 1682, when it was proposed to build tug-boats with wheels, worked by horses, for towing vessels against wind and tide ; but the first idea of applying steam to the propulsion of ships appears to be due to the celebrated Papin, who in 1690 proposed to propel boats by racks and pinions, with pistons working in steam cylinders. This ingenious inventor had thought out this scheme very well, and was only deterred from putting it in practice by want of funds, a disease from which — at the period in question — the Eoyal Society, to whom Papin had applied, suffered severely,. In 1737, Jonathan Hulls published a pamphlet, wherein he THE INSTITUTION OF CIVIL ENGINEERS. 91 gives a plate of a boat with a wheel attached to the stern, chiven by a steam-engine to propel the boat — tugging behind her a vessel of war. He took out a patent for the invention, but experienced so much opposition that he relinquished the project. New- comen's engine was proposed for propelling the wheel ; but the difficulty of producing rotatory motion with that kind of engine explains the abandonment of the design. Nothing more was done until 1765, when Dr. Eobison, of Edinburgh, proposed to James Watt to apply steam for propelling engines on land and sea. Watt, however, considered Newcomen's engine ill- calculated for this purpose, and devoted his entire energies to the perfection of his own form of engine, content to leave its manifold application to time. In 1782 the Marquis de Jouffroi tried a steamboat on the Saone at Lyons, but without success. About the year 1788 Fitch and Eamsay, of America, and Serrati, an Italian, are said to have made some experi- ments, with what success is not known ; and in the same year Miller, of Dalswinton, constructed a double boat, 60 feet long, with two paddle-wheels in the centre, moved by manual labour, and was convinced that Jpower alone was wanting to bring his idea to full fruition. Taylor proposed to employ steam, and applied to Symington, a practical engineer (who had previously proposed some improvements in New- 92 SCIENTIFIC LONDON. comen's engine, with a view to propelling carriages), to supply him with an engine. This experiment was successful, so far as it went, and was followed by others ; but the difficulty of avoiding an infringement of Watt's patent, and the trouble and annoyance occasioned by the opposition of mankind, induced Miller, Taylor, and Symington to abandon their invention and recur to their previous avocations. In 1801 Lord Dundas employed Symington to con- struct a steamboat propelled by an engine on Watt's plan, '* having one cylinder placed horizontally, and the piston, with a stroke of four feet in length, was jointed at the extremity, and attached to a connecting rod, with a crank at one end, turning a paddle-wheel, ]Dlaced in a well-hole at the stern of the vessel, w^hicli has two rudders, one on each side of the cavity in which the paddle-wheel was placed." This vessel was named the Charlotte Dundas, and answered its pur- pose — that of towing vessels on the Forth and Clyde canal — completely, but, as usual, a storm of prejudice had to be encountered. The proprietors of the canal objected to the boat, alleging that the ''wash" occa- sioned by the paddle-wheel would injure the banks of the canal. In the course of the next year the cele- brated Fulton, who had been for some time in England, went to Scotland and visited Symington, who made several trips up and down the canal, and fully ex- THE INSTITUTION OF CIVIL ENGINEERS. 93 plained every part of the boat and apparatus to Ful- ton, who observed that the objection of injuring the banks of small rivers and canals, which might apj)ly to England, would have no force in America, where things were on a larger scale. Having made notes of all particulars, Fulton went to France, built a steam- boat, tried it on the Seine in 1803, and soon after went to America. It is a cmious fact in the history of inventions that both the First Consul of the French Eepublic and the English people, then well acquainted with the use of the steam-engine, should have allowed this important discovery to slip through their fingers. Fulton, however, had no doubt of the importance of the invention, and pm'sued it with a tenacity thoroughly American. In 1805 he applied to Messrs. Boulton and Watt to make a steam-engine, and a^Dplied it to a boat built in America. This was the Clermont ■ — the wheels and machinery were on Symington's plan, propelled by Watt's engine. A speed of five miles an hour was attained ; and from this time Fulton con- tinued to construct larger boats, and applied to Boulton and Watt for more and more powerful engines. These efforts in America excited much attention in this country. In 1812 Henry Bell, of Glasgow, started the Comet to ply for goods and passengers on the Clyde, between Glasgow and Helensburgh. This boat only attained the same speed as the American 94 SCIENTIFIC LONDON. Clermont — five miles an hour. From this date the improvement in the construction of steamboats and marine engines was comparatively rapid. The side- wheel system superseded the stern-wheel and in 1814 Boulton and Watt first applied two engines to a small boat on the Clyde. In 1819-20 four steamers were working between Dover and Calais ; and by 1821 a line of steamboats was running between London and Leith. Meanwhile steam had been introduced into the Eoyal Navy, and Maudslay and Field had applied a valve for improving the expansive action of steam in the cylinder. In 1825 William Jolliffe, in conjunc- tion with Bessell and Hall, established the General Steam Navigation Company, and built two vessels of between five and six hundred tons burthen. These vessels were intended to ply between London and Cadiz and London and St. Petersburg, but the company considered the project of Jolliffe as rash, and restricted their operations to the British Channel and the German Ocean. In the memoir of the late Charles Wye Williams I find that about the year 1819 he — with the intention, originally, of assisting Mr. John Oldham, the engineer of the Bank of Ireland, and subsequently of the Bank of England — turned his attention to steam navigation, chiefly with the object of introducing Mr. Oldham's patent feathering paddles, which, after numerous THE INSTITUTION OF CIVIL ENGINEERS. 95 modifications, became known as " Morgan's wheel." Mr. Williams consulted with the late Mr. A. Manby, of the Horseley Ironworks, and thence was produced a small steam-engine with two oscillating cylinders, the first of its kind and the precursor of all those which have since been so extensively used on rivers and at sea, by John Penn and other engineers. These engines, with a pair of Oldham's feathering paddles, were adapted to a whale-boat, at the Eing's End Foundry, Dublin, by Mr. Charles Manby (Hon. Sec. Inst. C.E.), and the success was so great as to lead to the formation of a steam company for the conveyance of passengers and goods between Liverpool and Dublin ; and the company built, in 1823, the steamers City of Dublin and Town of Liverpool, each of 300 tons burthen. Mr. Williams was denounced as a bold and rash man to commence such a speculation with two ships. However, as it turned out, there was a call for more capital and ships, and four additional steamers were laid down, viz. the Hibernia, Britannia, Manchester, and Leeds. This growth of steam property caused the firm of Williams and Co. to merge into the firm of the " City of Dublin Steam Packet Company." At a later date Mr. Williams, in conjunction with Mr. Caiieton, launched the famous Peninsular and Oriental Steam Navigation Company. Eapid progress was now made in the construction 96 SCIENTIFIC LONDON. of marine engines. To obviate the inconvenience of the incrustation of boilers by the deposit of salt, Hall, of Dartford, introduced the system of surface conden- sation, while Maudslay and Field, in 1825, invented and patented their brine pumps, and Thomas Howard, of Eotherhithe, invented a refrigerator for pursuing the old system of condensation by jet. The next great event in the history of steam navigation was the crossing of the Atlantic by the Great Western, in 1838. This enterprise was due to the spirit of a Bristol company, with Brunei as their consulting engineer. Considerable difficulty was experienced in inducing engineers to attempt the construction of marine engines of sufficient power to drive a ship of 1240 tons burthen. Messrs. Maudslay and Field, however, undertook the work, and constructed a pair of engines on the side-lever principle, each of 210 horse-power, with cylinders 73 inches in diameter, and 7 feet stroke, making 15 strokes per minute. At her first trial on the Thames, the vessel went twelve miles per hour, and on the 8th April, 1838, started on her first voyage from Bristol, under the command of Captain Hosken, with seven passengers, 50 tons of goods, and 500 tons of coals, and reached New York on Monday, the 23rd April, thus accomplishing a distance of 3000 miles in thirteen days and ten hours. The success of this experiment, which surpassed the most sanguine THE INSTITUTION OF CIVIL ENGINEERS. 97 expectations of its promoters, opened the eyes of the world to the possible extension of ocean steam navi- gation. The famous Cunard line from Liverpool to Boston was designed for carrying the mails, and started with four fast vessels of about 1000 tons and 450 horse-power each. This was followed by the Eoyal Mail Company, for carrying the mails between England and the West Indies, starting with twelve vessels of somewhat similar dimensions. The radical defect of these early steamships was the enormous weight of the engines, and the great space requu-ed by them, which rendered it difficult for them to carry any great amount of cargo beyond the passengers. This serious inconvenience led to the devotion of much ingenuity to the improvement of marine engines. Messrs. Seawards were the first to introduce engines wherein side levers were dispensed with, and the power applied directly from the piston to turn the paddle-wheel shaft. This system was modified by Miller, who was very successful in obtaining high rates of speed, and the long-standing objection of extra friction was got rid of by adopting the vibrating cylinders described in Trevithick and Vivian's patent in 1802, patented by Witty in 1813, and by Manby in 1821, by whom the first engines of this kind were con- structed. Other improvements were adopted, and again improved upon by Maudslay and Field, Spiller, 98 SCIENTIFIC LONDON. Penn and Barnes, Miller, Seaward, Napier, Manbj, Fairbairn, Hall, Eennie, and many other able men who turned their attention to the extension and improvement of steam navigation. Just as the paddle-wheel was about to demonstrate its power to contend with the Atlantic waves, a rival propeller — destined ultimately to supersede it for ocean-going ships — sprang into existence. It was said by the late Sir John Eennie that " the first idea of stern-propelling was very probably suggested by the movement of fishes, whose chief propelling power exists in the tail, as also from the common and ancient practice of sculling a boat from the stern." Be this as it may, rude notions of a screw propeller had long floated in ingenious minds. Shorter, Napier, Tredgold, and Brown tried and described the action of propellers of various shapes applied to different parts of a vessel. Cameron, Woodcroft, Lowe, Ericson, and others, patented screw-propellers ; but nothing of positive value was effected until the year 1836, when the late Sir Francis Pettit Smith — since affectionately known as " Screw " Smith — obtained a patent for the appKcation of a screw to propel vessels by placing it in that part of the stern of the vessel called the "dead wood." He accordingly built a small vessel thirty- four feet long, and made experiments with her on the Thames. With this little boat he achieved a speed THE INSTITUTION OF CIVIL ENGINEERS. 99 of seven or eight miles an hour, and then tried her in a seaway. The Ship PropelHng Company was now formed, and, under the direction of Smith, the Archimedes was designed by Pascoe, built at London by Whimshurst, and fitted with engines and machinery by Kennie. At first the propeller consisted of a single-threaded screw; but this not answering very well, another screw was soon adopted with two threads opj)Osite to each other. The Archimedes was a success. She obtained a great velocity through the water, and proved herself an admirable sea-boat. The success of the screw propeller was now de- monstrated, and although vessels constructed on this system failed for awhile to accomplish the speed attained by those driven by the paddle-wheel, their superior power in a rough sea — since demonstrated beyond all possible question — induced the construction of the Rattler. Subsequently to this the Fairy, a Eoyal yacht, displayed the power of the screw in producing speed — this little boat of 260 tons burthen achieving 15| miles per hour through the water. Coincident with these improvements in the machinery of navigation, a new material was intro- duced for the construction of vessels. Hitherto birch bark, bull-hide, and wood had been the chief materials employed in making ships, but in 1820-21 Aaron Manby constructed, at Horseley, near Bu-mingham, 100 SCIENTIFIC LONDON. a wrought-iron boat of 120 feet length and 18 feet beam. This vessel, propelled by Oldham's feathering paddle-wheels, was built for the pm^pose of plying on the river Seine, and was navigated across the Channel by the late Sir Charles Napier. This boat continued to ply between Paris and Havre for many years, and although for a while superseded by other and more powerful boats, survived to wear out her engines, and, being fitted with new ones, held her own on the Seine for a long period. Notwithstanding the success of the Aaron Manhy, the art of iron shipbuilding developed slowly, and it was not until the fifth decade of the present century that ironships came into general use, since when it has been decided to build steamships of no other material. "While these great demands were being made upon the iron industry of the country, an important modifi- cation was introduced into the method of smelting iron. The low furnaces of the Middle Ages had long since been superseded by the blast-furnace, and coke had supplemented charcoal in the important work of reducing iron ore. Powerful blowing engines had been used, but hitherto they had been employed simply in forcing through the tuyeres atmospheric air at its ordinary temperature. In the first volume of the " Transactions of the Institution of Civil Engineers " is a noteworthy paper communicated by THE INSTITUTION OF CIVIL ENGINEERS. 101 J. B. Neilson on the hot-air blast. In 1836 this gentleman writes to the president — "About seven years ago an ironworker, well known in this neigh- bourhood, asked me if I thought it possible to purify the air blown into blast-furnaces, in a manner similar to that in which carbureted hydrogen gas is purified; and from this gentleman's conversation I perceived that he imagined the presence of sulphur in the air to be the cause of blast-furnaces working irregularly, and making bad iron in the summer months. Subse- quently to this conversation, which had in some measure directed my thoughts to the subject of blast- furnaces, I received information that one of the Muirkirk iron furnaces, situated at a considerable distance from the engine, did not work so well as the others ; which led me to conjecture that the friction of the air, in passing along the pipe, prevented an equal volume of the air getting to the distant furnace as to the one which is situated close by the engine. I at once came to the conclusion that by heating the air at the distant furnace I should increase its volume in the ratio of the known law, that air and gases expand as 448 + temperature. In prosecuting the experiment which this idea suggested, circumstances, however, became apparent to me which induced the belief on my part that heating the air introduced for supporting combustion into air-furnaces materially increased its 102 SCIENTIFIC LONDON. efficiency in this respect." The hot-blast came immediately into operation, and Mr. Neilson supple- mented his paper by some remarks which now read curiously enough. "Were the hot-blast generally adopted, the saving to the country in the article of coal would be immense. In Britain about 700,000 tons of iron are made annually, of which 50,000 tons only are produced in Scotland ; on these 50,000 tons my invention would save in the process of manufacture 200,000 tons of coal annually. In England the saving would be in proportion to the strength and quality of the coal, and cannot be computed at less than 1,520,000 tons annually, and taking the price of coals at the low rate of four shill'mgs per ton a yearly saving of a9296,000 sterling would be effected." It was indeed high time that a saving in the pro- duction of iron was effected, for a revolution was at hand, destined to transfer the carrying trade of the country from Brindley's canals and the magnificent highways designed by Telford to the iron roads now accepted as the ordinary means of transit. The history of great discoveries reveals two salient peculiarities. First is the cmious fact that at certain epochs the world becomes, as it were, ripe for the reception of great truths. From its four corners civilization addresses itself to the task of supplying THE INSTITUTION OF CIVIL ENGINEERS. 103 the recently discovered want. Inventors of various nationalities advance by different roads and distinct means towards the great object in view. Investigators working in entire independence of each other arrive almost simultaneously at the same conclusion. It would seem as if the human mind underwent periodical upheavings, and that outcrops of the same stratum of thought occurred in different localities. Instances without number may be cited — among others, those of Hooke and Newton, touching the law of the inverse square, of Watt, Cavendish, and La- voisier, on the composition of air and water, and of Adams and Leverrier in the discovery of the planet Neptune. It is by no means clear who invented gun- powder, and the merit of first printing by movable types is hotly disputed. The history of chemistr}^ abounds with illustrations of the law of simultaneous discovery. Without citing well-worn cases, I may quote a triple one. About twelve years ago the isomerism among the alcohols was simultaneously discovered in three separate countries by three inde- pendent sets of investigators in quest of entirely distinct objects : in Germany by Kolbe, in England by Wankljm and Erlenmeyer, and in Paris by Wurtz and Friedel. The second peculiarity is that no sooner is one class of mechanism brought to perfection than it is super- 104 SCIENTIFIC LONDON. seded by a fresh application of forces. Wind and water mills were no sooner perfected and fitted with the admirable mechanism invented by Smeaton, Ark- wright, and Hargreaves, than Watt introduced steam as the great motive power. Archery had just attained its most perfect development when gunpowder was discovered. The arts of attack and defence of fortified places have seen many mutations. Fortresses hitherto deemed impregnable were reduced by line and rule on the method of trenches introduced by the Turks and improved by Vauban, and a siege was deemed a mere matter of time when the experience of Silistria, Kars, and Sevastopol proved that plain earthworks could hold their own when revetements of solid masonry must infallibly have given way. The art of building and manoeuvring sailing ships had been reduced to a science, in the case of the famous yacht America, just as steam was superseding sailing ships altogether. Postal service had achieved perfection when the elec- tric telegraph was invented, and roads and coaches had been brought to the highest pitch of efficiency at the very moment when railways were to revolutionize the face of the world. But however the merit of England in great inventions may be shared by other countries, this latter is unquestionably and indispu- tably her own. About the commencement of the present century a THE INSTITUTION OF CIVIL ENGINEERS. 105 wild, eccentric man, named Trevithick — who had acquired some celebrity in the West of England as a mining engineer — succeeded in producing locomotive engines. In conjunction with Vivian and Blenkinsop he proposed ribbed wheels, with nails or bosses for the purpose of enabling the engine to ascend steep inclines. Previously to this date, rails or tramways had been made at various collieries throughout the kingdom, and flanges had come into almost common use. Dr. Eobison, James Watt, his assistant Mur- doch, and other inventors had calculated the pos- sibilities of introducing locomotives on common roads, but the high-pressure engine was by the best authorities considered unsafe. Undeterred by these considerations, Trevithick and Vivian constructed a locomotive engine for the Merthyr Tydvil Eailway. Working by adhesion alone, this engine, which " con- sisted of one high-pressure cylinder, with a fly-wheel and four bearing wheels — two of which were turned by the action of the piston — produced a velocity of five miles per hour dragging a load of fifteen tons." Unluckily for Trevithick, one of his engines exploded, and an accident which would have been deemed a mere trifle at the present day, and the costs whereof would have been calmly carried to the profit and loss account, sufficed — at the barbarous period referred to — to arrest the career of inventive genius for a time ; 106 SCIENTIFIC LONDON. but in 1811 Blenkinsop took out a patent " for using rails having teeth like a rack in them, into which wheels having corresponding teeth were worked by the engine, thus securing the engine against slipping." This departure from the principle of adhesion was ignored by Blackett, who in 1813 resumed Trevithick's original plan, and " constructed an engine which worked by adhesion alone upon the rails at the Wylam Colliery at Newcastle." At this hour a man was prepared to crystallize by the power of his genins these crude efforts into a practical shape. A keen, honest Northumbrian — the worthy father of a more worthy son — had advanced by this date to the position of engine-wright to Killingworth Colliery. Engaged during his leisure hours in superintending the education of his son, and in helping him to make a sun-dial by the aid of Ferguson's " Astronomy," George Stephenson bent his main energies towards the construction of a locomotive. This extraordinary man, who reached the age of eighteen without being able to read or write, had, in the following fourteen years, not only contrived to pull together a fair ''scratch education," but had so greatly distinguished himself by his successful treatment of an obstinate Newcomen pumping-engine as to have acquired the sobriquet of the " engine doctor." Continually making improvements in locomotives, Stephenson took out THE INSTITUTION OF CIVIL ENGINEERS. 107 patents, in conjunction with Dodd in 1815, and with Losh in 1816, and their productions were found equal, in 1820, to drawing coal trains at the rate of seven or eight miles per hour over the cast-iron edge rails recently introduced and patented by Birkenshaw. The Hetton and the Stockton and Darlington Rail- ways made by Stephenson were opened about 1825, and contained all the recent improvements in flanged wheels and wrought-iron rails. The first locomotive which ran on the Stockton and Darlington Eailway is, I believe, still preserved as a valuable relic, and regarded with much veneration by the natives of Darlington. James had already foreseen the develop- ment of the locomotive, and in 1815 published a letter, proposing railways as a regular mode of communica- tion ; but it was not till the Liverpool and Manchester Eailway Company obtained their first Act in 1826 — leaving the tractive power to be employed an open question — that the locomotive excited general public attention. The company employed Messrs. "Walker and Eastrick to report on the northern railways, and these gentlemen favom-ed the employment of stationary engines, while Stephenson and Eennie strongly advo- cated the introduction of the locomotive. Under these circumstances, the company offered a reward of five hundred guineas for the best locomotive engine. The result of the trial of the competing engines in 1829 108 SCIENTIFIC LONDON. electrified the world. The " Kocket," made by the Stephensons, attained the undreamt-of speed of twenty-five miles an hour, and decided the tractive question at once ; and the Liverpool and Manchester was opened in 1830, Mr. Huskisson proving the first victim to the iron-horse. Interesting in itself, and deeply valuable for the lessons conveyed by it, is the record of the fanatical opposition brought to bear against the new system. That powerful and gloomy giant known as Vested Interest arose in his might, and contested the ground inch by inch. Landowners rose in arms against Stephenson and his works, and professional engineers denounced him as a quack, and his scheme as the most absurd '' that ever entered into the head of man to conceive." Innumerable objections, practical and sentimental, were advanced. The railways would cut up the country, deform the face of Nature, burn up the crops, and throw entire districts out of cultivation. Cattle would be frightened to death, pheasants smoked out, the noble and im- portant pursuit of fox-hunting interfered with, and the country generally would, to use the time-honoured sentence, "go to the devil." How far these profound vaticinations have been realized, the present state of England and English industry can testify. Conscious of the disadvantage of a defective educa- tion, George Stephenson determined that his successor THE INSTITUTION OF CmL ENGINEERS. 109 should suffer from no such drawback, and made the training of his son the object of his earnest solicitude. No narrative can be more touching than that of the studious evenings passed by father and son together after the labours of the day. A severe course of study prepared the young man to render his father most valuable assistance not only in the great railway con- troversy, but in the actual construction of the famous locomotive which established their reputation. Taking with his father a prominent part in the construction of the English railway system, Eobert Stephenson did not confine himself entirely to the ordinary work of a railway engineer. As a builder of stupendous bridges on a new and original plan, he acquired a high rank. The tubular bridge across the St. Lawrence at Montreal, and the Britannia Bridge, across the Menai Straits, remain as enduring monu- ments to his splendid genius. In 1855 he was elected president of the Institution of Civil Engineers, a post which he filled with such ability as to reflect honour both upon himself and the distinguished body over which he presided. A most endearing trait in his character was his loving admiration for his great parent. In the course of his presidential address he said : '' It is my great pride to remember that what- ever may have been done, and however extensive may have been my own connection with railway develop- 110 SCIENTIFIC LONDON. ment, all I know, and all I have done, are primarily due to the parent whose memory I cherish and revere." Another remarkable instance of the hereditary transmission of engineering genius occurred in the case of the Brunels. Sir Mark Isambard Brunei made his mark in several branches of engineering science, notably in the invention of the celebrated block machinery, and in the general introduction of bands of thin hoop-iron between courses of brickwork — an important improvement which has been extensively used ever since — but his name is more particularly identified with the Thames Tunnel — a stupendous work previously proposed and commenced by Tre- vithick, but subsequently abandoned. The difficulties encountered in the construction of this tunnel were of a nature to test to the utmost the perseverance and ingenuity of the constructor. By the invention of the famous shield, Brunei exhibited his fertility of resource, and by the completion of a work, then unique in its character, placed his name for ever on the roll of illustrious engineers. During this great development of engineering genius the Institution of Civil Engineers had waxed mighty in the land. The institution was uniformly fortunate in the choice of its officials, but in the early days of its existence, under the presidency of Telford THE INSTITUTION OF CIVIL ENGINEEKS. Ill and the secretaryship of James Jones — to whom much of the credit of organizing the society is due — the finances failed to exhibit a prosperous aspect. The usual struggle for existence occurred. Many secre- taries were appointed, among whom is found the name of Captain (afterwards Colonel) Stoddart — one of the Central Asian pioneers, who at Bokhara suffered the fate often imposed upon travellers by barbarous nations. The name of Arthur Aikin — one of the founders of the Geological Society, the originator of the idea of the Zoological Gardens, the first president of the Chemical Society, and the famous secretary of the Society of Arts — also figures as honorary secretary to the Institution of Civil Engineers. After the death of Telford — who was interred in "Westminster Abbey — James Walker was called to the presidential chair in 1835, and it was under the presidency of this cele- brated engineer that the constitution of the society underwent a revolution, brought about mainly by the exertions of Mr. Charles (now Colonel) Manby. Mr. Thomas Webster (now Q.C.) held the appointment of secretary from 1836 to 1839, but on being nominated assistant to Judge Maule he asked his friend Mr. Manby to undertake his secretarial duties for a time. In 1839 Mr. Manby was appointed to the position, and at once put his shoulder to the wheel. In secur- 112 SCIENTIFIC LONDON. ing the services of this gentleman as secretary, the Institution was singularly fortunate, inasmuch as he not only possessed the true organizing faculty neces- sary to restore to the Institution its lost vitality, but was so happily situated as to be enabled to give a large portion of time to his labour of love. Under his care the society speedily gained strength, and has since asserted its existence with undiminished vigour. Fourteen years ago. Colonel Manby, whose exertions in the formation of an Engineer and Eailway Volunteer Staff Corps have recently been gracefully acknowledged by the Indian Government, and whose works — many of which were undertaken in conjunction with the lamented John Kobinson M^Clean — have met with ample recognition by foreign Governments, relin- quished the post of acting secretary for the honorary dignity, since which date the duties of secretaryship have been admirably fulfilled by Mr. James Forrest, to whose courtesy I am indebted for much of the material of this sketch. One of the principal changes brought about by Colonel Manby was the alteration of the term of presidentship. Feeling that the occupation of the chair for a long term of years by one individual, however distinguished, was prejudicial to the true interests of the society, he succeeded in inducing Mr. James Walker to resign the presidency in 1845, THE INSTITUTION OF CIVIL ENGINEEES. 113 since which date the presidents have been elected annually, although it is a custom of the Institution to confer on its chief officer the honour of one re-election. Since this important alteration in the constitution of the Society, only one president — Sir John Eennie — who sat from 1845 to 1848, has occupied the chair for more than two years. Without any design to expand the present sketch beyond its proper limits, I find it difficult to pass over without special notice the names of the distinguished men who have filled the presidential chair of the Institution of Civil Engineers. In 1846 Sir John Rennie, on his elevation to the dignity of president, delivered that remarkable address to which I, in common with all subsequent writers on engineering, am largely indebted for many important and interest- ing particulars. In the course of this admirable specimen of comprehensive arrangement and lacid exposition, the president alluded to the railway work already done, and ^' the mania for new lines, which has exceeded all former precedent. 1901 miles have been already executed on the narrow gauge, 2^4 on the broad gauge ; 614 miles are in progress of con- struction, and projects for 20,687 miles were actually introduced into Parliament last session, representing a capital of £350,000,000. Of these projects Acts of Parliament have been passed for 3573 miles, requiring I 114 SCIENTIFIC LONDON. a capital of £129,229,767." Only twenty-eight years have passed since these words were spoken, and the United Kingdom now hoasts over 15,000 miles of rail- way, representing a capital of £600,000,000 sterling. Sir John Kennie was succeeded by a man whose innate genius for mechanics had been developed by a course of severe training, and brought into prominence by a fortunate incident of which he took full advan- tage. After working under Sir Samuel Bentham at Portsmouth, young Joshua Field was brought up to the Admiralty at Whitehall to assist in the drawing department. At this period Mr. (afterwards Sir Isambard) Brunei was engaged on the famous block machinery then in process of construction by Maudslay . The latter gentleman requiring some assistance in drawing, applied to Sir Samuel Bentham to recommend him a competent draughtsman, when Sir Samuel and Mr. Goodrich strongly recommended young Field, who acquitted himself so well as to induce a permanent connection with Mr. Maudslay, whose partner he subsequently became. The famous house of Maudslay and Field has left its mark on the history of mechanical engineering. Besides occupying the first rank in the construction of marine engines, the house distinguished itself by its saw machinery, corn-mills, and mint machinery, and more especially by the construction of the first shield used in making the THE INSTITUTION OF CIVIL ENGINEERS. 115 Thames Tunnel. To Mr. Field, in conjunction with Mr. Henry Eobinson Palmer, Mr. William Nicholson Maudslay, Mr. James Jones, Mr. Charles Collinge, and Mr. James Ashwell, belongs the honour of found- ing the Institution of Civil Engineers. During the presidentships of Eennie and Field raged the ''battle of the gauges." On either side of this great question were ranged the engineering giants of the day. The broad gauge — already adopted on the Great Western Kailway — was w^armly advocated by the younger Brunei, an engineer of brilliant and daring genius, who, albeit his conceptions rarely produced pecuniary success, yet acquired well-merited renown by the grandeur of his inspirations, and left behind him the reputation of one whose splendid failures were perhaps more instructive, and possibly more valuable, to mankind than the positive achieve- ments of successful mediocrity. In the forefront of the opposing battalion stood the younger Stephenson, whose well-balanced intellect discerned at once the importance of carr^dng out great undertakings at a cost which should not entail ruin upon shareholders in order to enhance the reputation of the engineer. The result of this great conflict is now a matter of history, and the inclination now shown — wherever fresh ground is opened — to reduce the gauge to far narrower limits than 4 feet 8^ inches, demonstrates 116 SCIENTIFIC LONDON. the solidity of judgment displayed by the great North- umbrian. In 1850 Sir William Cubitt became president of the Institution. The career of this great engineer is one among many instances of gradual development. A miller's son with a taste for construction commenced by repairing the machinery of the mill, was subse- quently apprenticed to a joiner, and tried to make a machine for splitting hides. This, although a failure, showed so much ingenuity, that the young man was taken into partnership by an agricultural machine maker. After inventing the self-regulating windmill sails, Cubitt commenced the construction of machines for draining marshes, and ultimately achieved extra- ordinary success in drainage works, canal making, and the construction of docks at Cardiff and Middles- borough. Turning his attention to railways, he — as engineer-in-chief — constructed the South-E astern Eailway, " where he adopted the bold scheme of employing a monster charge of 18,000 lb. of gun- powder for blowing down the face of the Bound Down Cliff, between Folkestone and Dover, and then con- structing the line of railway along the beach, with a tunnel beneath the Shakespeare Cliff." To the ear of the malefactor the name of Cubitt had an awful sound, as that of the inventor of the treadmill. The chair was now successively filled by two THE INSTITUTION OF CIVIL ENGINEERS. 117 hydraulic engineers of the highest rank. James Meadows Eendel, after acquiring considerable reputa- tion by his success in bridge building, devoted his attention more particularly to the construction of harbours and docks. Among his achievements may be enumerated the Birkenhead Docks, the new docks at Grimsby, and the Great Western Docks at Plymouth. Here he first introduced the method of construction since employed with so much success at the great harbours of Holyhead and Portland. In each of these great works many natural obstacles were overcome. At Grimsby the works were projected far out upon the mud-banks of the river Humber, entirely beyond low- water mark, and great difficulty was experienced in laying the foundations, owing to the treacherous nature of the substratum. Born in the same year — 1799 — as Mr. Eendel, and succeeding him as president in 1854, James Simpson had previously turned his energies to the construction of waterworks, and designed and executed in 1828 at the Chelsea Waterworks his first filter bed, which had an area of about one acre, and proved so completely successful that no material alteration has been made in the system of filtration since that time. During the course of a long and prosperous career, Mr. Simp- son constructed the works at Seething Wells and designed the extensive works for bringing to Bristol the 118 SCIENTIFIC LONDON. springs and streams of the Menclip Hills. He also designed and executed the works for supplying Aber- deen with water taken from the river Dee, about twenty miles above the city, and, indeed, may be said to have made this department of engineering science peculiarly his own. From 1856, when Eobert Stephenson became presi- dent, down to the present day, the chair has been chiefly occupied by railway engineers. Stephenson was suc- ceeded by Joseph Locke, who has been styled the third great leader of the engineering world,the two first places being conceded to Stephenson and Brunei. Singularly enough, these three great engineers were born within two years of each other, and within a similar space quitted the scene of their labours. One of the most salient characteristics of Mr. Locke w^as his keen ap- preciation of economy ; he may indeed be said to have made his reputation by constructing the Warrington and Birmingham — then designated the Grand Junction Eailway — within the estimate, at a cost of between ^14,000 and £15,000 per mile. The commercial world was attracted by this valuable result, and Joseph Locke's reputation as an economical engineer assured him the direction of many great undertakings. He achieved much good work by discouraging the intro- duction of engines of various forms and by various makers on the same line, and by insisting on a THE INSTITUTION OF CIVIL ENGINEERS. 119 system of uniformity in order to insure economy and promptitude in repairs. Mr. Locke left no monu- mental works behind him, but he has left a monu- mentum cere perennius in the hearts of grateful share- holders who have drawn dividends from his lines, while the ambitious labours of his rivals reduced them to the verge of impecuniosity. Only last year the engineering world deplored the loss of John Eobinson M^'Clean, who became president in 1864. This gentleman, who was a son of the late Francis M^ Clean, of Belfast, was born in that city in 181B, and was educated at the Koyal Academical Institution. At the age of twenty-one he went to Glasgow, where his career was exceedingly brilliant. Studying for two sessions under Professors Thomson, Meikleham, and Sir W. Jackson Hooker, Mr. M^ Clean obtained high honours in the classes of mathematics and natural philosophy, and at the same time pursued practical studies in mining engineering and survey- ing. On the completion of his university career, he entered the of&ce of Messrs. Walker and Burges, civil engineers, 23, Great George Street, Westminster, and remained with them until 1844. During his stay with these gentlemen, Mr. M^ Clean assisted in preparing the surveys and contract drawings of the improve- ments in Belfast Harbour, and other important public works undertaken by Mr. Walker ; but in 1844 the 120 SCIENTIFIC LONDON. rising young engineer determined to assume the inde- pendent exercise of the profession in which he after- wards took an active and distinguished part. In the very inception of his independent career he became the engineer-in-chief of the Furness Eailways, and from that time forward v^as intimately associated with the great pubhc works of that remarkable district, including the Barrow Harbour, Barrow Docks (which rival the famous docks at Birkenhead), graving-docks, railways, and other works. The modern history of Barrow-in-Furness is a record of rapid development unparalleled in the annals of industry. Haematite ore had long been known to exist in large quantities in this remote corner of Lancashire, but the develop- ment of the iron mines of Furness dates from the introduction of the railway system. The growth of Mr. M^ Clean's fortunes more than kept pace with the sudden extension of railways. Born at the very nick of time, he found himself in the possession of his full powers at the moment when the railway system — like a young giant — stretched forth its iron arms towards every point of the compass. Never was opportunity more readily seized. Pursuing his advantage with unfailing energy and untiring industry, Mr. M^ Clean soon found him- self in the foremost rank of his profession. He did not confine himself to the construction of rail- THE INSTITUTION OF CIVIL ENGINEEES. 121 ways, for when an agitation was commenced about the polluted state of the Thames, which, in 1849, was becoming full of sewage, and engineers were invited by the Metropolitan Commissioners of Sewers to send in plans for the drainage of London, the rising man failed not to contribute his scheme, and had the satis- faction of finding it most favourably viewed by the Commissioners, who considered it "the best conceived and most practicable scheme submitted to them." In 1849 Mr. M*^ Clean received into partnership Mr. F. C. Stillman, and the new firm at once engaged in the construction of the South Staffordshire Eailway and branches, the Birmingham, "Wolverhampton, and Dudley Eailway, the Staffordshire and Worcestershire Canal Eeservoirs, and the South Staffordshire Water- works, supplying water to a population of nearly half a million. In the year of the first Great International Exhibi- tion, Mr. Maclean carried out extensive works in Paris, and, on the death of Mr. Walker, was appointed Government engineer to the harbours of Dover, Alderney, and St. Catherine's, the Plymouth Break- water, and the Shovel Eock Fort at Plymouth. During the next fifteen years the successful engineer enjoyed the full tide of popularity. He was at once consulting engineer to the Birmingham Canal Navigation and the Bute Docks at Cardiff, and engineer to the Surrey 122 SCIENTIFIC LONDON. Commercial Docks, the Tottenham and Hampstead Junction Kailway, the Bristol and Portishead Pier and Kailway, the Cannock Chase and Wolverhampton Kail- way, the Furness and Midland Eailway, the Eyde Pier Company, and numerous other public works in Great Britain. He also held the post of consulting engineer to the Lemberg-Czernowitz Austrian Eailway and the South-E astern of Portugal Eailway, and was, moreover, a fellow of several scientific societies. Mr. Mc Clean was preceded in the chair by Mr. George Parker Bidder — the bosom friend of Eobert Stephenson — and by Sir John Hawkshaw. The career of George Bidder affords a peculiar instance of the triumph of method. The famous " calculating boy " has invariably disclaimed the possession of any extra- ordinary amount of memory, and has openly stated that a certain degree of jproficiency in the art of mental calculation is within the reach of almost every one. In a remarkable paper on mental calculation, read by Mr. Bidder before the Institution of Civil Engineers in the year 1856, he explained with singular lucidity and happiness of illustration the operations performed by his mind while at work upon figures, and insisted very strongly on his favourite doctrine — that mental arithmetic can be taught like anything else. The whole course of his argument is against the necessity for original genius, and in favour of the THE INSTITUTION OF CIVIL ENGINEERS. 123 theory that the slow and gradual acquirement and the orderly arrangement of facts are the principal qualities demanded of the mental calculator. He proceeds thus : — *' I do not, however, mean to say that it ought to be taught, or that it is desirable to attempt to teach it, to the extent to which I have been enabled to carry it. I have sacrificed years of labour, I have striven with much perseverance, to obtain and to retain a power or mastery over numbers which will probably, at all times, be as rare as is its utility in the ordinary affairs of life. Far be it from me, however, to say that it has been of little use to me. Undoubtedly the acquirement has attracted towards me a degree of notice, which has ended in raising me from the position of a common labourer, in which I was born, to that of being able to address you as one of the vice-presidents of this distinguished Society. But, as I have already said, I am not about to lay before you any abbreviated process of calculation ; there are no " royal roads" to mental arithmetic. Whoever wishes to achieve proficiency in that, as in any other branch of science, will only succeed by years of labour and of patient application. In short, in the solution of any arithmetical question, however simple or complicated, every mental process must be analogous to that which is indicated in working out algebraical formulae. No 124 SCIENTIFIC LONDON. one step can be omitted ; but all and every one must be taken up one after another, in such consecutive order, that if reduced to paper the process might appear prolix, comjDlicated, and inexpeditious, although it is actually arranged with a view of affording relief to the memory. And here let me say, that the exercise of the memory is the only real strain on the mind, and which limits the extent to which mental calculation may be carried. It may be imagined that this is some- what inconsistent with my previous observation that I possess no extraordinary power of memory. But it must be borne in mind that my memory is the limit by which my mental powers are restricted ; and that the processes I pursue are all adopted, simply with a view of relieving the registering powers of the mind, i.e. the memory. ■ " I can perhaps convey to you no stronger view of this subject than by mentioning, that, were my powers of registration at all equal to the powers of reasoning or execution, I should have no difficulty, in an in- conceivably short space of time, in composing a voluminous table of logarithms ; but the power of registration limits the power of calculation, and, as I said before, it is only with great labour and stress of mind that mental calculation can be carried on beyond a certain extent. Now, for instance, suppose that I had to multiply 89 by 73, I should say instantly 6497 ; THE INSTITUTION OF CIVIL ENGINEERS. 125 if I read the figures written out before me I could not express a result more correctly, or more rapidly ; this facility has, however, tended to deceive me, for I fancied that I possessed a multiplication table up to 100 times 100, and, when in full practice, even beyond that ; but I was in error ; the fact is that I go through the entire operation of the computation in that short interval of time which it takes me to announce the result to you. I multiply 80 by 70, 80 by 3 ; 9 by 70, and 9 by 3 ; which will be the whole of the process as expressed algebraically, and then I add them up in what appears to be merely an instant of time. This is done without labour to the mind ; and I can do any quantity of the same sort of calculation without any labour, and can continue it for a long period; but when the number of figures increases, the strain on the mind is augmented in a very rapid ratio. As compared with the operation on paper in multiplying three figures by three figures, you have three lines of four figures each, or twelve figures in the j)rocess to be added up ; in multiplying six figures into six figures you have six lines of seven figures, or forty-two figures to be added up. The time, therefore, in registration on paper will be as 12 to 42. But the pro- cess in the mind is different. Not only have I that additional number of facts to create, but they must be imprinted on the mind. The impressions to be made 126 SCIENTIFIC LONDON. are more in number, they are also more varied, and the impression required is so much deeper, that instead of being hke 3 or 4 to 1, it is something Hke 16 to 1. Instead of increasing by the square, I beheve it in- creases by the fourth power. I do not pretend to say that it can be expressed mathematically, but the ratio increases so rapidly that it soon limits the useful effect of mental calculation. As a great effort, I have multiplied twelve places of figures by twelve places of figures ; but that has required much time, and was a great strain upon the mind. Therefore, in stating my conviction that mental arithmetic could be taught, I would desire it to be understood, that the limits within which it may be usefully and properly applied should be restricted to multiplying three figures by three figures. Up to that extent, I believe it may be taught with considerable facility, and will be received by young minds, so disposed, quite as easily as the ordinary rules of arithmetic." In 1862 Sir John Hawkshaw became president. During a highly successful career this gentleman has been engaged on many works of the first magnitude, among which may be cited the Lancashire and York- shire Eailway, the Charing Cross Eailway, and Lon- donderry Bridge. Sir John Hawkshaw also acquired great reputation by the resource displayed by him on the failure of the Middle Level sluice at St. Ger- THE INSTITUTION OF CIVIL ENGINEERS. 127 mans, near Lynn, where, instead of constructing a new sluice, he invented and erected syphons for the drainage of the district. Sir John Hawkshaw is an engineer of advanced ideas, and is a warm advocate of the Anglo-French tunnel under the Channel. In 1866 Mr. M^ Clean was succeeded by Mr. John Fowler, an engineer of the first rank, who has con- structed lines in nearly every part of England, the Great Northern and Western systems in Ireland, the Metropolitan Eailway, and numerous other railways in and around London. Between 1868 and the date of writing, the chair has been occupied by four engineers of the highest distinction. Charles Hutton Gregory — a son of Dr. Gregory, the distinguished Professor of Mathematics at the Eoyal Academy, Woolwich — was brought up in the works of Messrs. Bramah and Co., and was early in life appointed the resident engineer of the Croydon Eailway. He subsequently became connected with the Bristol and Exeter, and all the lines of railway within that district, and has latterly been generally consulted by the Crown Agents for the Colonies. Mr. Charles Blacker Vignoles holds one of the oldest commissions now extant in the British army. He was on active service in Spain, and distinguished himself in a " forlorn hope," whence he was lucky enough to escape with a whole skin. On the advent of 128 SCIENTIFIC LONDON. "piping times of peace," he turned his mathematical knowledge to good account, and, as became the grand- son of old Dr. Hutton, he embraced the career of a civil engineer. Mr. Yignoles constructed many notable works in England, and also took his share in the parliamentary fights of the last generation. He then turned his attention to Eussia, where he made several lines of railway, and the famous Kieff suspen- sion bridge. Mr. Vignoles has also had a large share in constructing the railway system of South America. Mr. Thomas Hawksley — who succeeded Mr. Vignoles as President of the Institution of Civil Engineers — commenced life as a surveyor, but speedily attained celebrity as a surveyor for water and gas, and has designed and constructed many important works at Nottingham, Liverpool, and other places. In the present year Mr. Hawksley gave place to Mr. Thomas Elliot Harrison. This gentleman was brought up in the office of Eobert Stephenson, in whose estimation he stood very high on account of his clearness of judgment and fertility of resource. Mr. Harrison has acquired deserved celebrity by the construction of the High-Level bridge at Newcastle, and of the docks and other great works connected with the North -Eastern Eailway. The illustrious roll of presidents, and the record of their achievements, form after all but a small part of THE INSTITUTION OF CIVIL ENGINEEBS. 129 the history of the Institution of Civil Engineers. Among the members are Sir William Armstrong, who achieved celebrity by the invention of the hydraulic crane and the gun which is called after him ; his great rival in the manufacture of ordnance, Sir Joseph Whitworth, the founder of the famous Whitworth scholarships; Dr. C. W. Siemens, whose researches in metallurgy have acquired for him a world-wide reputation ; James Abernethy, James Brunlees, J. F. Bateman, Joseph Bazalgette, Sir William Fairbairn, Isaac Lowthian Bell, Sir George Elliot, William Menelaus, and many more able engineers and in- ventors, to mention all of whom would be a lengthy task. Suffice it to say that during the last half-century the genius of English engineers has displayed its power in every region of either hemisphere. While the vast peninsula of Hindostan was being knit to- gether by iron bonds, an enterprising band of English engineers laid the foundation of the railway system of South America. The success of the Maua Eailway — designed and constructed by Edward Brainerd Webb — opened the eyes of the Brazilians to the value of railway communication in a country of such " magni- ficent distances" that railroads are the only possible roads. From Brazil the desire for railways spread to the Eiver Plate, where many important railways have 130 SCIENTIFIC LONDON. been made, and others are still in course of construc- tion by Mr. Webb and other eminent engineers. On the transandine side of the continent much has also been done in facilitating means of communi- cation and opening up to commerce the immense resources of South America. The Peruvian Govern- ment is constructing, under the advice of Mr. Edward Woods, about 500 miles of railway, and the Chilian Government about 300 miles. Eailways have also been introduced into Japan; but the offer of a railway to the Emperor of China has not yet met with a cordial acceptance. Nearer home many great works have been undertaken, among which may be cited the Amsterdam Ship Canal — now being executed under the direction of Sir John Hawk- shaw and Mr. Dirks — and large additions to the dock accommodations of Liverpool. To these last it was originally proposed to add several of Mr. Edwin Clark's hydraulic docks; but the invention of the pneumatic floating dock by Messrs. Latimer Clark and Standsfield has led to the adoption of the newer and far more economical substitute. It is gratifying to find that, in the great race of life, English engineers still hold their own, but it is also worthy of remark that the professors of an important and exclusively modern department of engineering have not hitherto been deemed worthy of the highest THE INSTITUTION OF CIVIL ENGINEERS. 131 honours conferred by the Institution of Civil Engineers. Perhaps the existence of a " Society of Telegraphic Engineers " explains the seeming oversight ; for, although no member of the army of electricians has 5^et occupied the post of President of the Institution of Civil Engineers, the society in Great George Street has shown no reluctance in taking to her bosom these professors of a new science. In fact the Institution is sufficiently catholic in its views, and opens its doors to no less than four classes of persons. Honorary members are '' distinguished persons " not engaged in the practice of the profession. Among the fifteen honorary members are the Emperor of Brazil, the Prince of Wales, the Duke of Connaught, and General Todleben. The members number 793, and have already been — so far as space will permit — individually referred to. In addition to the actual members, 1295 associates are enrolled. These gentlemen are not necessarily civil engineers by profession, but must be qualified to concur with civil engineers in the advance- ment of professional knowledge, and moreover must, like the actual members, have attained the age of twenty-five years — a highly salutary regulation. Ex- press provision is made for the admission of students, who must be between eighteen and twenty-six years of age, and must be or have been pupils of members or Associates of the Institution. At the present moment 132 SCIENTIFIC LONDON. 289 students are admitted to many of the most im- portant privileges of membership on paying a sub- scription of <£2 2s. per annum. A few years since the Council of the Institution made an inquiry into the present system of educating engineers both at home and abroad, and elicited much valuable information ; but in consequence of a feeling among the members that it was better to let things alone, nothing was done. Experts on the Continent, as well as in England, expressed grave doubts con- cerning the advantage of a severe training in the sciences bearing upon the profession before engaging in its actual practice. In true English style, the systems adopted in France and Germany were decried as producing a race of great schoolboys, who knew nothing " practical," were childishly ignorant of mechanical engineering, and displayed at critical moments an utter absence of that fertility of resource which is one of the characteristics of the English engineer. This is all excellently well, but at the same time those Englishmen who have been contaminated by foreign influences may be excused if they decline to consider theoretical knowledge a positive drawback in the engineering or any other profession. Continued insistence on the virtues of the "practical man" is apt to render one weary of that overpraised individual. It is easy to admire his joluck, his resource, bis handi- THE INSTITUTION OF CIVIL ENGINEERS. 133 ness in overcoming difficulties, but it is now and then impossible to resist the conclusion that, if the prac- tical man had possessed a little more scientific know- ledge, he would have found fewer difficulties to over- come. The whole question appears to be mainly one of time. At first sight, it is of course dreadful to think of arriving at manhood without having acquired anything but theory ; but, on the other hand, it is questionable whether the time invested in scientific study is not rapidly recouped when the young theorist is set to practical work. On the one hand is the fault into which the universities of Oxford and Cambridge have fallen, viz. that of keeping men at school till they are twenty-three years old, an age at which a man ought not only to have left school, but have acquired at least the power of doing work in some walk of life ; while on the other is the obvious disadvantage of bringing up a race of half-educated youths, whose only chance of getting on in life is to blunder on from failure to failure, until success is achieved more by force of character than by constructive skill. Possibly the true technical education — like many other things — has yet to be discovered. Members, associates, and students of the Insti- tution are alike stimulated to exertion by many premiums and medals, for which ample funds have been provided by the Telford, Miller, and Howard 134 SCIENTIFIC LONDON. bequests, and the Manby donation. Interesting pro- ceedings take place at the ordinary meetings of the Society, which are often protracted over several sittings. The papers read are considered the property of the Institution, and for this or some other inexplic- able reason, the press are severely enjoined not to publish any record of the proceedings beyond the official precis of the original paper presented to them by the Society. In many cases of great public interest this policy of restriction is severely felt. The griev- ance is not so much that only a precis of the original paper may be reported, but that the discussion is entirely reserved for the Transactions of the Society. A notable instance of the inconvenience occasioned by this rule occurred last year. A great debate was expected on a subject of the highest importance — no less than the break of gauge in India. I found the great room of the Institution crowded with eager debaters and anxious listeners. Mr. Thornton's able paper provoked a discussion which will long remain in my memory as one of the most remarkable for interest and vivacity that I have been privileged to witness. For months the public remained in a benighted state on the Indian railway question, simply because the publication of the discussion on the most interesting question before the engineering world was impossible, except through the ordinary official medium. I THE INSTITUTION OF CIVIL ENGINEERS. 135 As for myself, I enjoyed the proceedings immensely, simply because I was not allowed to write about them, and my appreciation of the argumentative power and the opposite theories of the great engineers who entered the arena was not dimmed by the knowledge that- work was then and there by me to be performed ; but on leaving Great George Street, after each brilliant meeting, I could not help regretting that before the record of the discussions could reach the public eye the heat of battle would have passed away, and the Indian railway question — undergoing the fate of other questions — have crystallized into a lifeless thing of the past. 136 SCIENTIFIC LONDON. V. THE CHEMICAL SOCIETY. One of the first to recognize the truth that science has in modern times acquired a range not to be comprised by any one institution, the Society of Arts has ever been ready to assist the formation of any association having a special object, and has recently established special sections of its own, such as the Indian and the Chemical Section. Specialty is, indeed, one of the salient features of the nineteenth century. Special knowledge and special power are everywhere in demand. In law, in the arts, and more especially in science, the specialist is looked upon with a peculiarly favourable eye. Mankind gratefully acknowledges its obHgations to the man who devotes his life to the attainment of perfect knowledge within a certain narrow sphere. Never was the " Jack of all trades and master of none" doctrine more implicitly received than at the present moment ; and never was the THE CHEMICAL SOCIETY. 137 " life-view " (as he calls it) of my friend Professor Engestrom so generally accepted. The professor — who is constantly insisting that the aim and object of life cannot be too early decided upon and too rigorously adhered to — is fond of citing the instance of the famous grammarian who devoted his life to the dative case. Doubtless this scheme of life, leaving the world's work to be done by infinite division of labour, does not meet with much sympathy from old-fashioned people, who incline to the idea that more perfect manhood is achieved by a general student than by a narrow specialist. These well- meaning people urge that in olden times men were more many-sided than they now are, and that one individual might be a good soldier, sailor, lawyer, and politician, and therefore enjoy a fuller life than his descendant of to-day ; but it behoves us to recollect that it was not difficult to know all that was to be learned four hundred years ago. The recorded wisdom of the western world might have easily been contained in a hundred tomes, and, with the exception of mathe- matics, science in its exact sense was unknown. Astronomy, struggling in the trammels of traditional cosmogonies, was largely mingled with astrology. Botany was confined to the enumeration of the pro- perties of simples plucked under certain lunar in- fluences. Chemistry was in the alchemical stage, 138 SCIENTIFIC LONDON. busying itself with the elixir vitse ; and the metallurgy of the period consisted of researches into the ima- ginary transmutation of metals and the vain pursuit of the philosopher's stone. During the last two centuries more advance in scientific knowledge has been made than during all the thousands of previous years, but it is during the present age that facilities of communicating thought and its results have led to the splitting up of the sciences into minute divisions and subdivisions. As lawyers have divided law until the pursuit of each narrow branch has become a distinct profession ; as doctors have dissected the human body and divided it among them, one taking the eye, and another the ear, the brain, the heart, the lungs, the throat, or the stomach as his peculiar domain of research ; so has the mantle of Friar Bacon or of Schwartz — fit repre- sentatives of the ancient alchemist or astrologer — been cut up into many fragments, and distributed among astronomers, naturalists, physiologists, botan- ists, geologists, physicists, metallurgists, palaeontolo- gists, and chemists. The immense development of chemical research in this country by Davy, Dalton, and their contempo- raries very naturally suggested the formation of a society having for its object the advancement of chemical science. It is true that the Eoyal Society THE CHEMICAL SOCIETY. 139 was always ready to welcome the accomplished chemist, and it would argue slight knowledge of the history of chemistry to overlook the brilliant dis- coveries made in the laboratory of the Eoyal Institu- tion, but it was, nevertheless, felt that a special society was needed for the encouragement of chemistry as distinguished from physics and other cognate sciences. It was thought that chemistry had at length grown big enough to have — like the ancestral O'Donoghue — a ^'boat of its own," and the important bearing of the newly-developed science upon the industry of the country was urged as a powerful and tempting argument in favour of stimulating chemical investigation. The honour of the initiative is due to Mr. Eobert Warington, who convened a meeting for the purpose of taking into consideration the formation of a Chemical Society. The meeting was held in the well-known rooms of the Society of Arts on February 23rd, 1841. Among those present were the excellent and ubiquitous Mr. Arthur Aikin, W. E. Grove, Lyon Playfair, and Professor Graham, who occupied the chair. The formation of a Chemical Society having been resolved, the objects of the Society were declared to be the promotion of chemistry, and of those branches of science immediately connected with it, by the reading, discussion, and subsequent publication of original communications, and the formation of a 140 SCIENTIFIC LONDON. cliemical library and museum. The annual subscrip- tion of members resident within twenty miles of London was fixed at two pounds, and of those residing beyond that distance at one pound. Thomas Graham was elected the first president ; J. T. Cooper, W. T. Brande, J. F. Daniell, and K. Phillips, vice-presidents. Arthur Aikin — still full of energy — was appointed treasurer ; and Eobert Warington and E. F. Tesche- macher, secretaries. A council was appointed, the names of seventy-seven gentlemen who had become members were then read, and the Society adjourned until Tuesday, the 13th April. The Society now continued to meet regularly from time to time, and between 1841 and 1847 pub- lished three volumes of Memoirs and Eeports of Proceedings. At the latter date the members numbered between two and three hundred, and it was therefore considered desirable that steps should be taken for obtaining a Eoyal Charter of Incorporation, which was granted in the following year. In accord- ance with this document, the Chemical Society consists of Fellows, honorary and foreign Members, and Associates. The Fellows elect out of their own body a governing council consisting of a president, four or more vice-presidents, a treasurer, two secretaries, a foreign secretary, and twelve other Fellows. At the present moment the presidential chair is filled by Dr. THE CHEMICAL SOCIETY. 141 Odling, and among the vice-presidents who have filled the office of president are found the familiar names of Brodie, Frankland, Hofmann, Lyon Playfair, and Williamson. Mr. W. H. Perkin and Dr. Enssell are the efficient secretaries ; Dr. Hugo Miller fills the post of foreign secretary, and Mr. Abel acts as treasm-er. Other magnates of the chemical world figure in the list of the council, notably Drs. Eoscoe, Maxwell Simpson, Stenhouse, and Armstrong. The post of librarian and editor of the Society's journal — a duty much increased of late by the incorporation of translations of foreign papers — is ably filled by Mr. Henry Watts, whose tremendous " Dictionary " is a lasting witness to the way in which he jierforms his valuable work. Candidates for admission to the Society are proposed on a form of recommendation subscribed by five Fellows of the Society at least, three of whom recommend the neophyte from " per- sonal knowledge," while the remaining two may recommend from *' general knowledge" — whatever that precise form of knowledge may be worth. After being balloted for and duly elected by three -fourths of the voters, the new Fellow pays an admission fee of two pounds and his first year's subscription or life- composition, and is then received into the bosom of the association by the president, who, taking him by the hand, says, '' Mr. , I do, by the authority 142 SCIENTIFIC LONDON. and in the name of the Chemical Society, admit you a Fellow thereof." At the present moment the Fellows number about eight hundred. Of the Associate — a species of *^ free-list subscriber" — only one instance exists. The number of foreign Members is limited to forty, but on this list are found many of the most illus- trious names in the history of chemistry. First on the roll stands Balard, the discoverer of bromine ; and next to him Berthelot, who contributed to chemical science the Syntheses of Formiates, of Alcohol, and of Acetylene. Boussingault, famous by his researches into the Chemistry of Vegetation, follows next, and precedes the illustrious Bunsen, whose name is rendered dear to the scientific world by the invention of the Bunsen burner, by the perfection of gas analysis, and by the discovery of caesium, and rubidium, and the spectrum analysis. Next follows Cahours, whose researches in potato sj)irit, and determination — in conjunction with Hofmann — of the phosphorus bases, are fresh in the memory ; Canizzaro, made famous by the Synthesis of Aromatic Alcohols, and his considera- tions on Atomic Weights from Specific Heat ; and Chevreul, identified with the Chemistry of Fats and the Theory of Colours. The name of Deville recalls aluminium ; and that of Dumas the Theory of Types and Organic Analysis. Many other famous chemists are on this remarkable list — notably THE CHEMICAL SOCIETY. 143 Wohler, of Gottingen, who, so long ago .as 1828, established the Synthesis of Urea, and Wurtz, the discoverer of Glycol and Ethylamine ; Stas, well known by his researches on Atomic Weights ; and Kekule, of Bonn, identified with Atomicity and Thiacetic Acid. Two great names now challenge attention. Kolbe, of Leipzig, celebrated by the Electrolysis of Fatty Acids — by the Synthesis of Formic Acid from nascent Hydrogen and Carbonic Acid — by the Synthesis of Oxalate of Sodium from Carbonic Acid and Sodium, and by the Theory of Isomeric Alcohols. Pasteur has not only written his name in the history of chemistry by his discovery of optical differences in Amylic Alcohol and in Tartaric Acid, but has become famous in physiological contro- versy by his experiments in biogenesis. Conducted in a truly philosophical spirit, these famous experiments form an epoch in the long contest between the advocates and opponents of the theory of spontaneous generation. From its foundation to the present day, the Chemical Society has done much good solid work. Eecorded among its proceedings are many papers which have left their mark on the history of chemistry. From its earliest days the Society has shown a keen appreciation of Teutonic research, and has devoted much time and pains to the translation of papers by eminent German chemists. In 1841 translations were 144 SCIENTIFIC LONDON. read of the papers on " Cacodyl Compounds," con- tributed by Professor Bunsen, then of Marburg. During the next two years Dr. Stenhouse read many papers before the Chemical Society. Aniline now attracted the attention of Muspratt and Hofmann — in whose laboratory Perkin was destined to discover the commercial value of mauve. Hofmann himself com- municated papers on the Metamorphoses of Indigo, and on Styrole. In 1845 Hofmann pursued his researches on aniline, and in 1848, while professor at the Eoyal College of Chemistry, contributed to the Society his researches on the Volatile Bases, including the papers on the " Action of Cyanogen on Aniline, Toluidine, and Cumidine," on the " Action of Iodine on Aniline," and on the " Action of Chloride, Bromide, and Iodide of Cyanogen on Aniline." "While Hofmann was pursuing this line of investigation, Kolbe and Frankland were making researches into the nature of the Organic Eadicals, and Liebig contributed papers from time to time. In 1857 Church and Perkin communicated the results of their study of '' some new colouring matters, Derivatives of Dinitrobenzole, etc.," and Mr. Perkin followed this by a paper on the " Action of Cyanogen on Naphthalamine." At this period Dr. Lyon Play- fair also sent in papers on the '' Nitro-Prussides," and other subjects. THE CHEMICAL SOCIETY. 145 In 1858 Wanklyn communicated a paper on the Synthesis of Propionic Acid, followed at a later date by the Synthesis of Propione, and in 1863, then working in conjunction with Erlenmeyer, produced Hexylic Compounds from Mannite. In the pages of the Journal of the Chemical Society, Kopp has recorded his investigations into the Specific Heat of Solid Bodies, and Kolbe his Synthesis of OxaHc Acids and his Prognosis of New Alcohols and Aldehydes. The late Ernest Chapman read papers on many subjects — in particular on Limited Oxidation. In 1867 a paper describing the Ammonia Process of Water Analysis was communicated by Wanklyn, Chapman, and Smith ; and was followed in the next year by the rival system of Frankland and Armstrong, which brought about a vigorous controversy. Dr. Frankland, working in conjunction with the late Mr. Duppa, also produced some excellent papers on Ethide of Boron and on the Eeduction of Oxalic Ether to Leucic Ether by the action of Zinc-Ethyl. The year 1868 was marked by Dr. Siemens' paper on the Eegenerative Gas Furnace as applied to the manufac- ture of cast steel ; and more recently Isaac Lowthian Bell contributed a valuable paper on the Chemistry of the Blast-furnace. The Chemical Society is one of those highly favoured L 146 SCIENTIFIC LONDON. bodies wliich, like the Eoyal Society and the Geological Society, are permitted to occupy a portion of Burling- ton House. A magnificent suite of rooms is allotted to it. There is a handsome library, admirably appointed, and enriched by a fine collection of chemical works, and regular files of English and foreign scientific periodicals. Adjoining the library is the inevitable tea-room, without which the domain of no scientific society is complete. Beneath these apartments is the great room of the society, fitted uj) with benches in ascending order, like those of an ordinary lecture-room. Behind a long table, more or less encumbered with chemical specimens and apparatus, sit the president and the two secretaries — the two latter gentlemen being charged with the onerous duty of reading papers in the absence of their authors. The presence of a number of ballot-boxes reveals the fact that several gentlemen recommended on the basis of " personal " or " general " knowledge are up for election ; and the reception of many recently-elected Fellows, according to the form pre- scribed, indicates that the Chemical Society is adding largely to its list of members. This is a cheering sign, but my spirits are slightly dashed when I observe the extreme youth of many among the audience. As the names of the visitors — of whom each Fellow may introduce two — are read aloud, I find that their THE CHEMICAL SOCIETY. 147 number does not account for the remarkable pre- ponderance of young gentlemen. On inquiry I find that these must, therefore, be actual Fellows. I naturally experience some little surprise at this dis- covery, as I was once inclined — in the innocence of my heart — to attribute a certain distinction to the mystic letters F.C.S. Now, no human being is more incKned to encourage youth, and more disposed to regret its loss, than myself. It has long been an article of my creed that when a man is able to do good work, he is old enough to be entrusted with it, and I never lose an opportunity of insisting that in life the '' time " is not, as musicians say, "taken quickly enough," but I find it difficult to resist the conviction that many of the juvenile Fellows of the Chemical Society cannot possibly have attained any higher rank than that of students or of assistants to lecturers. I may be mistaken. The young gentlemen referred to may have attained eminence in the chemical world, or the letters F.C.S. may not be intended to convey any grave significance, but I confess that I am puzzled. Elections over, the reading of papers is proceeded with. Many of these are important, and a particularly interesting account of researches in Phenol is read by Dr. Armstrong, the chemical professor of the London Institution. Time passes quickly, and the attention given to the business of the evening is 148 SCIENTIFIC LONDON. perfectly warranted by its engrossing character. Much revolving these things, I at length emerge into Piccadilly admiring the youth of the Fellows of the Chemical Society, and wondering why a powerful body hke this, possessing a fine library, has yet no museum of its own. ( 149 ) VI. THE DEPAETMENT OF SCIENCE AND AET. It would be difficult to find a more curious and in- structive illustration of the growth of English institu- tions than the Science and Art Department of the Committee of Council on Education. In other ignorant countries — such as France, for instance — there is always a Minister of Public Instruction, a sort of chief schoolmaster, who is supposed to look after the education of the million ; but in this country it was long deemed unnecessary to create a minister without any perceptible functions. Five-and-twenty years ago there was little talk about education, and, so far as the many were concerned, there was none. The reports of Government inspectors have clearly demon- strated that the so-called teaching of the National Schools practically amounted to nothing, and could hardly be designated education without provoking a laugh. Since then much has been done in the way 150 SCIENTIFIC LONDON. of educating the loeople, and the Lord President of the Council has been called upon to fulfil in England the duties assigned abroad to the Minister of Public Instruction. This procedure is intensely English. A brand new office, created to supply a fresh and growing want, would hardly have suited the insular genius. We had a Lord President of the Council whose duty apparently was to perform presidential instead of, as was said of the archdeacon, " archi- diaconal" functions. He was paid a good round salary, and should be made to work for it. Hence education is represented in the Upper House by the Lord President, and in the Commons by the Vice- President of the Council, to the great delight of Englishmen, who love to explain to the " intelligent foreigner" that, although they have no special Minister of Instruction, they yet have the thing under another name. The Department of Science and Art was formed out of three more or less elementary bodies — the Depart- ment of Practical Art, the Royal College of Chemistry, and the Eoyal School of Mines, whereof the second has been long since absorbed by the third, which, although now included under the General Department, enjoys a distinct existence, a separate constitution, and a clearly defined income of its own. I would fain have discoursed in separate essays on the rise. THE DEPARTMENT OF SCIENCE AND ART. 151 progress, and ultimate destiny of these several insti- tutions, but this Gordian Imot is all too toughly interlaced to yield to my blunted penknife. So far as my limited powers go I will endeavour to set forth the pecuHar functions of each body, but dissever them I neither must nor may. All are now linked together .under the broad title of the Department of Science and Art. The Department was regularly constituted in 1853 by a Minute of the Treasury, in consequence of the rej)resentations of the Board of Trade (under whose jurisdiction the Department of Practical Art, ^bove alluded to, was at that time included), was j.3laced under the Committee of Council on Educa- tion, and during the first six years of its existence was mainly employed in reorganizing the system of Art Instruction. Without going into the particulars of the purchase of the Gore House Estate — bought partly with the surplus funds left in the hands of the Eoyal Commis- sioners for the Exhibition of 1851 — it may be sufficient to state that the late Prince Consort induced the 'Government of Lord Palmerston to build the well- known "Brompton Boilers," at a cost of a615,000, the Commissioners giving the land, for the purpose — in the first place — of exhibiting the collection of pictures presented to the country by Mr. Sheepshanks on the iexpress condition that the donor should see a building 152 SCIENTIFIC LONDON. erected to receive his gift. Subsequent additions to> the "Boilers" afforded room for the pictures till then exhibited in Marlborough House, to which the old Schools of Design held at Somerset House and else- where were transferred for a while — ultimately to find their home in South Kensington. A Parliamentary grant of ^910,000 was devoted to this latter purpose, and South Kensington became the fulcrum of the Art teaching of the country. Unwilling that the metro- polis should absorb all the advantages of artistic instruction, Mr. Henry Cole, the Secretary of the Department, undertook the onerous task of extending these benefits to the entire country through the in- strumentality of parish and other local schools. The old Schools of Design had been encom-aged after a peculiar fashion. Grants of money were made to certain towns on the condition that they should them- selves furnish an equal sum to that contributed by the State ; for instance, Manchester received ^600 on condition that that city should add an equal sum. This system was exposed to many disadvantages. In the first place, the Government grants were difficult to get. Kidderminster strove in vain for a grant on the ground that the manufacture of carpets required a School of Design, and Stourbridge pleaded her glass manufactures without success, while in those cities where schools actually existed the Government almost THE DEPARTMENT OF SCIENCE AND ART. 153' invariably got the worst of the bargain. Local contri- butions came in slowly. In many cases it was found impossible to keep faith with the Government, and the results were lamentably incommensurate with the outlay of public money. It was at once seen that until a properly organized staff of teachers was formed nothing valid could be done, and energetic measures were taken to supply this need. A body of properly certificated teachers was formed. These instructors received at first a certain salary, coupled with an addi- tional remuneration, according to the results of their teaching, shown by their pupils under examination. Ultimately this plan — which was not without merit of its own— was superseded by the system of " payment for results." For the first six years of its existence, from 1853 to- 1859, the Department found Art easier to manage than Science, and experienced very great difficulty in organizing the scientific branch. Until the year 1859, elementary instruction in science was hardly attain- able by the artisan. It is true that some of the principal mechanics' institutions scattered over the great towns had from time to time ''popular" lectures on scientific subjects, illustrated frequently by experi- ments, diagrams, or specimens, but these lectures rarely extended to systematic courses. In very few institutions were any classes for collective instruction. 154 SCIENTIFIC LONDON. scarcely any had laboratories, and whatever collec- tions of natural objects existed were almost always ill-arranged and incomplete, even for the pm'poses of very limited instruction. A few exceptions to this description existed in Glasgow, Edinbm-gh, Man- chester, Liverpool, and London, but in the smaller towns, and in manufacturing and rural districts, no instruction was to be acquired. Various attempts had been made to remedy this state of things. The creation of a Central Science School in the metro- polis was strongly recommended, but has not been carried out to this day. Meanwhile attempts were made to kindle into life what were called Trade Schools. These proved such a conspicuous failure, that when the late Lord S alisbury became Lord President of the Council, he resolved that he would either abolish the word Science out of the title of the department, or he would cause some science to be given to the country. Accordingly, about the year 1859, certain principles were laid down which enabled the Department to encourage the teaching of certain sciences bearing upon industry. These principles have since been carried much further. Stated briefly and broadly, the system now at w^ork is, that any locality that pleases may establish a Science School or class. It may be held — in the words of Mr. Cole — in a garret, THE DEPARTMENT OF SCIENCE AND ART. 155 or may be held in a cellar, without concerning the Department in any way, unless a grant in aid of building be asked for — when certain conditions are insisted on. The teachers are appointed by the local committees, and must have proved their competency by examination. The local committee simply notifies the Department that it has constituted itself, and may then proceed to teach any one or all of the twenty- three sciences enumerated in the Science Directory, and may request that at a certain period of the year the students be examined. The examination is conducted by papers sent down from the office in London, and on the results the teachers get payments, and the students prizes. Pay- ments are made on behalf of those who are interpreted to belong to the artisan class — clearly defined in the Science Directory — but the prizes are open to all. The theory is that the artisan class pay moderate fees, and the middle classes larger fees. Gratuitous instruction is now abolished, the payment of fees being insisted upon as a qualification for undergoing examination. Teachers are paid by results, that is, 80 much per student of the artisan class that passes examination successfully. The payments are in the following proportions : — ^1 for every second class, in either the elementary or the advanced stage ; ^2 for a first class in either of these stages, or for a second 156 SCIENTIFIC LONDON. class in honours, and £4 for a first class in honours. The object of this system of remuneration is to directly encourage the formation of a class of teachers of elementary science, and to stimulate them to activity by granting payment for "results" alone. The suc- cess of this plan has been rapid. In 1860, 500 persons were under instruction in nine schools; in 1867, 10,230 persons were under instruction in 212 schools ; while in 1870, 34,283 persons were taught in 799 schools. From 1870 to 1872 the rate of increase slackened, as no more than 36,783 persons are re- ported as having been instructed during the latter year. Fourteen of these obtained gold, twenty silver, and thirty-three bronze medals, while 5931 received prizes. Between 1872 and 1873 a tremendous leap was made, the number reported under instruction in May, 1873, being 48,546, to whom sixteen gold, eighteen silver, and thirty-four bronze medals, and 7215 prizes were given. The expenditure of the Science and Art Depart- ment during the financial year 1872-73, exclusive of the vote for the Geological Survey, amounted to ^209,117 2s. 2cZ., and with the addition of ^£21,385 Is. granted for that important object, reached the grand total of ^230,502 3s. 2^. In the succeeding financial year 1873-74, the total expenditure reached £262,503, showing an increase of j£32,000 16s. lOd., and in the THE DEPARTMENT OF SCIENCE AND ART. 157 current year, dating from the 1st April, 1874, to the 31st March, 1875, it is proposed to devote an increase of £15,667 to the Department of Science and Art bringing up the estimates to £278,170. This sum, £278,170, is distributed as follows :— Administration of Science and Art Department £5,422 Schools of Science and Art 120,110 Purchases and Circulation 23,682 South Kensington Museum ... 38,024 Services common to the several divisions ... 28,177 Branch Museum, Bethnal Green ... ... 5,810 School of Mines and Geological Museum ... 8,998 Edinburgh Museum 9,824 Royal Dublin Society 1,823 Botanic Gardens (Dublin) ... 2,148 Leinster Lawn (Dublin) 200 Museum of Natural History ... 1,672 Library (Dublin) 1,677 Royal College of Science (Dublin) 6,883 Royal Hibernian Academy ... 300 Royal Zoological Society of Ireland ... ... 500 Geological Survey of United Kingdom ... 22,920 "Without going into minute details of increase and decrease, it may be said briefly that £168 is saved on the item Administration, £605 on Purchases and Circulation, £372 on the South Kensington Museum, and £445 on the Eoyal Dublin Society. An increase of £877 is devoted to Services Common to both Departments, £240 to Bethnal Green, £592 to the 158 SCIENTIFIC LONDON. Edinburgh Museum, and ^£253 to the Geological Survey. It is, however, gratifying to record that .-£15,550, or nearly the entire net increase, is devoted to the Schools of Science and Art, raising this item from £104,560 in 1873-74 to ^9120,110 in 1874-75. The total increase under this head is put down at d£15,550, but a saving on the School of Naval Archi- tecture (now removed to Greenwich) of ^0310, and a deduction of £50 from scholarships, bring the net amount disposable for other branches up to £15,910, distributed thus : — Schools of Science and Aet.

Digby Wyatt, C. W. Cope, E.A., R. Eedgrave, E.A., F. E. Pickers^ gill, E.A., H. Weekes, E.A., J. C. Horsley, E.A.,. F. Leighton, E.A., and J. Marshall, F.E.S., with assistants. In Science, the examination papers are prepared by Professors Tyndall, Frankland, Huxley, and Percy, with their able staff of assistants. The papers prepared by these high authorities are sent down into the country, and the pupils are examined them in presence of the committee, the teacher being rigorously excluded from the building, and by the result of these papers the pass degrees or honours, gold, silver, and bronze medals and other prizes, are awarded to the pupils, and the capitation fees assigned to the teachers. The sum which has been increased to £40,500 in the present estimates, and is put down as " Science," is entirely devoted to the payment of science teachers "by results." Few will cavil at the gross amount distributed among the science teachers of the country, especially when regard is had to the immense amount of work done for it. Capitation fees for successful pupils 160 SCIENTIFIC LONDON. in the proportion of one, two, and four pounds per head, according to the degrees of efficiency exhibited under examination, may be satisfactory enough as ■*' encouragement " to the teachers, but barely answer io the demand for sufficient remuneration for work ■done. As a stimulant to exertion the premium on results is well enough without doubt, but it holds out a prize not always to the swift, nor even to the strong, but often to the lucky. In writing on scientific subjects it is always w^ell to eliminate the element of ■chance, if possible ; but in the case of popular educa- tion it is not always possible to achieve this feat. Into scientific teaching chance enters largely. To begin with, the teacher may have dreary up-hill work. The district wherein he is called upon to lecture may be swayed by adverse influences. Noble pursuits, such as dog-fighting and nurr-and-spell, may hold out superior attractions to some, while cricket and skittles may deflect other pupils from the science class. Admitting that the absorbing influence of these truly British pastimes may be overcome, and a fair class attendance secured, the ieacher still has to contend with numerous disadvan- tages. His pupils may be below even the average level of stupidity. He may talk and he may experi- ment, but if the material of his class be thoroughly dense his labours may prove vain. Another difficulty THE DEPARTMENT OF SCIENCE AND ABT. 161 arises from those indolent or balf-liearted students who, imagining that they have acquired the smatter- ing they deem necessarj^, shirk the examination, the results of which alone entitle their pastor and master to remuneration. Laziness and a childish fear of breaking down also help to deprive the master of his fair exhibit. Worse than all of these is a selfish indifferentism, which induces pupils to disregard the master's interests altogether so long as their own turn is served. Against all these adverse influences the Science teacher has to contend, and it therefore hardly seems fair to deny him all remuneration except by '^results." As a i3roof of the injustice that frequently occurs, I may cite the case of a Science teacher who took high honours, and who yet by the "result" system only received £7 for a course of sixty experimental lectures in his first year of teaching, since when — during the last four or five years — he has delivered ninety lectures per annum, and has earned from ^12 to ^26 by each com-se. As this is by no means an isolated case, it would appear that the hard and fast Hne of payment "by results alone" may be advantageously departed from by granting teachers a small salary — say of 5OIO or ^12 per annum — as a species of guarantee against actual dead loss of time. The large range of subjects included in the advanced stage of M 162 SCIENTIFIC LONDON. chemistry is also j)ointed out by the teachers as a si3ecial source of hardship. They declare that students are unable, within a reasonable time, to master the numerous obligatory subjects sufficiently well to face the examiner, and that therefore a vast amount of care and painstaking on the part of the master never has a chance of being recomj)ensed either by pence or praise. In order to set forth clearly what is at first sight not very distinct, I may say at once that the items previously enumerated include all that is done for Science by the Department as such, save and except the courses of instruction given for the express benefit of Science teachers. Art is taught directly to pupils at South Kensington, but Science is not — by the Department. There are laboratories at South Kensing- ton where pupils and " Science Teachers in Training" receive instruction, but these are more particularly devoted to the School of Mines. No Science, then, is directly taught by the Department (which only encourages others to teach), exce^^t to the teachers themselves. Lectures are given in summer by the professors of chemistry, physics, and other branches, with the express object of enabling country teachers to obtain a knowledge of the latest discoveries and newest experiments. These lectures were commenced in 1869, were attended with great success, and have since THE DEPARTMENT OF SCIENCE AND AET. 163 l^ecome a regular part of the summer programme of the Department. It has been customary to afford such country teachers as have taught two years con- secutively, and passed not less than thirty students each year, second-class railway fare to London, and £3 towards then* expenses of living while there. For the future this arrangement will probably be modi- fied in order to enable a certain number of teachers to stay long enough in London to undergo a course of instruction in teaching certain special subjects. Should this scheme be carried out, such teachers will receive 305. per week instead of one payment of £S. Science teachers, then, enjoy the privilege of attend- ing these lectm-es on condition that they do their work thoroughly. They are required to make notes, to afterwards write out a complete report of each lecture, and also to take part in practical work. The reports are examined by the professors, and marks are awarded in accordance with the merit displayed. No less important is the practical teaching given in the laboratories, especially when it is recollected that the object of these courses is to enable teachers to give practical instruction in the several sciences. This plan has called into existence a system of tuition in practical science which has already borne good fruit. Students, instead of being confined to mere 164 SCIENTIFIC LONDON. listening to lectures, are now taught to perform, and' to assist in performing, experiments with their own hands. This system has produced a promising crop of students, of whom about forty-five are at present prosecuting their more advanced studies in the labor- atories of the Eoyal School of Mines under the title of Science Teachers in Training. Time and space permit — for the present — the extension of this latter advantage to a limited number only, but it has been suggested that a most desirable improvement would be made by permitting such promising pupils as are in the habit of assisting their teachers in experiments to listen to the lectures at South Kensington. While at work in their own classes the teachers are subject to visits from the Government inspectors, selected for the most part from the officers of the Eoyal Engineers. There can be no doubt as to the conscientiousness with which these gentleman dis- charge their duties, but it is possible that the number of inspectors is not sufficiently large, inasmuch as I am imformed that certain classes — not of the most obscure order — escape inspection for years together. A Science teacher of some experience tells me that for- five years he was never once honoured with a visit of inspection, although his class is held at a well-known spot in the heart of London. Complaints of this kind indicate distinctly enough that the rank and file of THE DEPARTMENT OF SCIENCE AND ART. 165 4^cience teachers do not feel very well satisfied at being placed under the inspection of a body of gentle- men who, although possessed of high scientific attain- ments, have had comparatively slight experience of -actual teaching. Perhaps the teachers think that their future inspectors ought to be drawn from their own body — but this by the way. Pupils are encouraged by the offer of a large number of Exhibitions, Scholarships, Medals, and Prizes. Among these the Eoyal Exhibitions to the School of Mines, the Whitworth Scholarships, the Pioyal Exhibitions to the Eoyal College, Dublin, and the privileges conferred on the gainer of a gold medal at the May Examinsition are the most important, but these are supplemented by many local and conditional prizes and exhibitions, grants for laboratories, etc. The whole system is now in fair working order, and during the last fifteen years has produced results as important as they were unexpected. Having now sketched slightly the past and present of the famous Department of Science and Art, taken in its entirety, I may proceed to advert to those scientific institutions which combined with the Depart- ment of Practical Art to produce the vast network of Art and Science schools with which the country is rapidly becoming covered. It is true that the Eoyal College of Chemistry exists no longer as an actual 166 SCIENTIFIC LONDON. coi'iDoration, but an account of scientific culture in England would, nevertheless, be incomplete without some notice of that institution. Travellers down Oxford Street will observe a build- ing now converted into a general Medical Council House, looking grimly enough at its neighbour, the Eoyal Orthopaedic Hospital. This establishment — albeit financially a failure — has left no slight mark on the history of science. It was once called the Eoyal College of Chemistry, and during its short span of existence saw much notable work ]Derformed within its walls. The college was first established by a public meeting held in St. Martin's Place, on the 29th July, 1845. Form was given to the new insti- tution by the election of a council and the appoint- ment of certain executive officers. Eooms were next hired in George Street, Hanover Square, as labora- tories, but it was soon found necessary to secure a more convenient and permanent habitation. Ulti- mately premises in Hanover Square, with a frontage to Oxford Street, were secured, and the most eminent architects and chemists were consulted as to the formation of an economical and convenient edifice,, with the most efficient arrangements for the opera- tions of the laboratory. On the 16th of June, 1846,, the first stone of the building was laid by the late Prince Consort, the President of the college, who had THE DEPARTMENT OF SCIENCE AND ART. 167 already conferred immense benefit upon the college by persuading Dr. August Wilhelm Hofmann to preside oyer it. This celebrated chemist had commenced a brilliant career as assistant in the chemical laboratory of the University of Giessen. He subsequently held the appointment of Professor Extraordinary at the University of Bonn, but in 1845 forsook the banks of the Khine for those of the Thames, and became Pro- fessor of the Pioyal College of Chemistry in London. After filling this chair for several years. Dr. Hof- mann — pending whose possible retui-n Dr. Frankland accepted the post of provisional professor — was sum- moned to Germany to preside over the erection of new laboratories at Bonn and at Berlin, and was prevailed upon to remain in the Prussian capital — a resolution which it is dimly rumoured he has since had cause to regret. During his residence in London, Dr. Hofmann added greatly to his scientific reputation by carrying out his classical researches on ammonia — showing the successive replacement of hydrogen by various organic radicals — in the laboratory of the Eoyal College of Chemistry. He also, in conjunction with the eminent French chemist M. Cahours, dis- covered a remarkable series of phosphorus repre- sentatives of the compound ammonias. Meanwhile, a discovery of the utmost industrial importance was made in his laboratory. Perkin, in the course of 168 SCIENTIFIC LONDON. some preliminary investigations into the possibility of producing artificial quinine, discovered the famous Perkin's mauve while oxidizing aniline with chromate of potash. This discovery brought its author into well-merited fame — albeit it was well known at the time — when mauve, if not discovered for the first time as a colour, was at least for the first time made commercially valuable — that the technical knowledge and enterprise of a dyer at the East end of London, who ably seconded the exertions of the chemist, con- tributed largely to the industrial value of these investigations. Fortunately, or unfortunately, it was discovered, or thought, that successful philosophical investigation barely compensated for financial failure, and the Eoyal School of Chemistry became a doomed institu- tion; not destined, however, to absolute extinction, but rather to absorption, as tottering principalities are sucked into the vortex of neighbouring empires. Pure science was in this case destined to cede the place to technical education. Again, under the auspices of the late Prince Consort a new and vigorous organization had sprung into active life, and becoming in its vigorous growth too large for its own habitation, acquired that of the dwindlmg College of Chemistry as a sort of scientific chapel of ease. The council of the college, despairing of sue- THE DEPARTMENT OF SCIENCE AND ART. 169 cess, handed over the building, valued at ^3000, to the Government, on condition of a claim of some ^500 being settled; and thus in 1853 the College of Chemistry became the laboratory of the Eoyal School of Mines, under the condition that it should retain its original designation. The origin of the School of Mines lies deep down in the primary strata of technical education, and was due, in the first place, to the enterprise of the late Sir Henry de la Beche, in undertaking single-handed the Geological Survey of the United Kingdom; and, in the second, to the English habit of adapting existing institutions to immediate wants. As is well known, the survey undertaken at first by Sir Henry de la Beche, at his own cost, underwent a gradual expan- sion, and, as the value of the work became apparent, received more and more support from the State. In 1837 Lord Duncannon, Chief Commissioner of Woods and Forests, allotted apartments in Craig's Court to receive the collection which has since developed into the Museum of Practical Geology in Jermyn Street. In 1851, when the latter building was opened, the sm'vey had assumed imposing proportions. Its work- ing staff contained not only practical geologists and field-surveyors, but a naturalist, a mining surveyor, a mineralogist, a metallurgist, and a chemist. In the same year numerous memorials, praying for 170 SCIENTIFIC LONDON. the establishment of a mming school, were addressed to the Government. It was m-ged that — though the value of the annual mineral produce of this country amounted to £28,000,000, equalling four-ninths of the total amount produced by the whole of Europe, and far exceeding that yielded by any other State — "the miners and metallurgists of the United Kingdom were unable to obtain that instruction in the theory and the practice of their calling, which had long been carefully provided for their foreign comjpetitors in the mining colleges of France, Belgium, Prussia, Saxony, Austria, Spain, and Sweden, and the effect of which in all cases had been a marked increase in the economy, efficiency, and safety of mining operations.'* The voice of the representatives of the mining interest was raised at the right moment. Finding ripe and ready to hand the complete nucleus of a mining school in the officers, laboratories, and collec- tions of the Geological Survey, the Government lent a willing ear to the request of the memorialists. In 1851 the School of Mines was instituted, all its pro- fessors being, with one exception, officers of the Survey and Museum. The existing establishment was further utilized. Students were taught in the theatres and laboratories appertaining to the Museum ; where, surrounded by specimens and models, they possessed every opportunity of profiting by the prescribed course THE DEPARTMENT OF SCIENCE AND ART. 171 of instruction. As has already been stated, the laboratories soon outgrew the resources of Jermyn Street and were transferred, firstly, to the Eoyal College of Chemistry, and, lastly, in 1872, to South Kensington. Certain parts of the work, however, are still done in Jermyn Street. Thus, while Messrs. Frankland, Huxley, Guthrie, and Goodeve — the lecturers on Chemistry, General Natural History, Physics, and Applied Mechanics — have transferred their habitat to South Kensington, Messrs. Wariiigton Smyth, Percy, and Ramsay — the lecturers on Mining and Mineralogy, Metallurgy, and Geology — still pursue their labom-s amid the illustratiye specimens with which the Museum of Practical Geology abounds. The School of Mines is governed b}' a Council of Professors, whose resolutions are carried into effect by the Registrar, Mr. Trenham Eeeks. To the lectm*es given by this institution the public are admitted on payment of three or fom* pounds, according to the length of the course, and are granted certificates of attendance, but students wishing for certificates of proficiency are compelled to pass the examinations. Those, however, who desire an official certificate constituting them Associates of the Eoyal School of Mines are required to follow^ a course of study extending over three years, and to pay a sum of thirty pounds on entrance, or to make two annual 172 SCIENTIFIC LONDON. payments of twenty pounds each, exclusive of labora- tory fees. This plan of instruction, combining systematic courses of lectures, written and oral examinations, practical teaching in the laboratories and drawing office, and also — under certain conditions — field excursions, is of a thoroughly scientific and, wdthal, technical character, and is, perhaps, the best extant English representative of the admirable system of technical education in force in Germany, Switzer- land, and France. For the first two years a general training is insisted upon, but after the second year pupils may attach themselves to any one of the three divisions prescribed, and may take a first-class in only one of these divisions if preferred. This very rsound and practical plan of study commences m the first year with inorganic chemistry, with practice in the laboratory, and mechanical drawing. In the second year pupils are taught physics, with practice in the laboratory, applied mechanics with demonstra- tions, mechanical drawing and mineralogy. Having completed these courses, pupils may in the third year *'go out" in either of the three following divisions : — The Mining Division, comprising mining, assaying, and geology ; the Metallurgical Division, trained to metallurgy in the laboratory ; or the Geological Division, including natural history, with practice in the laboratory, geology, and palgeonto- THE DEPARTMENT OF SCIENCE AND ART. 173^ logical demonstration. Altliougli the course of in- struction is spread over three years, persons may, if possessed of sufficient knowledge or industry, save time by getting through the whole and their examina- tion in a couple of years, while those who have already mastered the subjects set down for the fii'st two years may proceed to the courses of the third year by passing the final class examinations in those subjects. It is hardly necessary to say that those persons who desire the title of Associate are the peculiar pride and care of the Eoyal School of Mines. Among these are the Eoyal Exhibitioners. There are nine Eoyal Exhibitions to the School of Mines, of the value of .^50 each per annum. The holders are entitled ta *'free admission to all the lectm-es and the chemical and metallurgical laboratories " for three years, on condition of compliance with the rules, regular attend- ance, and the passing of the examinations required for the associateship. As a rule, three of these exhibitions become vacant every year, and are open for competition at the May examinations of the Science and Art Department, independently of the other prizes offered by that department. All persons over twenty-one years of age — excepting artisans and such persons as are paid upon under the " Science Directory," that is to say, broadly, persons whose income is under c£200 per annum— are excluded from 174 SCIENTIFIC LONDON. competing for the Eoyal Exhibitions. It is pleasing to record that these exhibitions have produced really ■good fruit. Many young men sprung from the true artisan class have won them well, and worn honour- ably the subsequently acquired title of Associate. Apart from the Eoyal Exhibitioners and persons desiring associateship, many others are offered strong inducements to pursue the course of study prescribed by the institution. Those who have taken either a first or second-class certificate in " the advanced stage in any subject in Science at the exhibition held by the Science and Art Department, and who show that they are bond fide Science teachers, may attend the day lectures gratuitously, provided that they be •examined in at least one subject, paying a fee for each examination of one pound per course." Officers of the Army and Navy, Her Majesty's consular and diplomatic officers, officers of the Crown at home on furlough, and acting mine agents and managers of mines are admitted to the lectures at half-price. Moreover, those who obtain a Queen's Gold Medal at the annual May examination of the Science and Art Department receive the privilege of attending all lectures and examinations free. Students of the Eoyal Schools of Mines compete for two scholarships of thirty pounds each, granted by H.E.H. the Prince tains a classified collection of the minerals once desig- nated non-metalliferous. Chief among these rank the- diamond and the *' black diamond." A superb snuff- box, presented to the late Sir Eoderick Murchison by the Emperor Nicholas of Eussia, and bequeathed by the recipient to the Museum, occupies a place of honour among many other specimens of pure carbon. Less beautiful, but far more important than the diamond, is the great modern motive power — coal. The varieties of coal form a regular series, commencing with hard coal, or anthracite, and passing through the ordinary bituminous coals to the more recently- formed lignite. Here are numerous specimens of true anthracite, of cannel coal, lignite, and jet, of the curious mineral known as Bog-Head cannel, and of Kimmeridge coal and other hydro-carbons, such as asphalt, elaterite, and amber. Considerable space is- devoted to coal and to the method of "winning" it- There are models of the " surface workings of a Newcastle coalpit," of the " Shipley Colliery in Derby- shire," and of the different modes of working and ventilating coal mines. In addition to these are found one of Eidley and Co's coal-cutting machines,, and siDecimens of the tools employed in various mining districts. Immediately above the coal-cutting, machine is an interesting collection of ancient. Saxon THE MUSEUM OF PBACTICAL GEOLOGY. 263 mining axes, richly ornamented. These formed the badges of office among the chief miners, and were only carried on State occasions. It is curious to trace the gradual steps by which a miner's axe became by degrees more highly ornamented and reduced in weight, until at length the ancient axe shrank to the dimensions of a practicable walking stick — a mere wand of office. In case 5, in the model room, is a complete collec- tion of mining lamps, showing the inventions of Davy and Stephenson, and the improvements subsequently made in them, among which is the remarkable magnet-lamp invented to prevent the miner from opening his lamp to light his pipe. In the upper gallery is a fine collection of British fossils, admirably arranged for the use of students; but it is impossible to do more than allude to the numerous objects of interest in the Museum of Practi- cal Geology. Several cases in the haU are filled with polished cubes of British ornamental stones, collected to assist the deliberations of the Building- Stone Com- missioners appointed to select the best possible stone for building the present Houses of Parliament. An immense deal of trouble was taken in testing the physical and chemical properties of the various stones, but the selection arrived at can hardly be designated a success. Another most interesting relic is a portion 264 SCIENTIFIC LONDON. of the boulder-stone used for the sarcophagus of the late Duke of Wellington. A huge boulder had long lain supine in a field in Cornwall, to the despair of the farmer, who on several occasions proposed to blow it up, but was deterred by the menaces of the country folk, who, by addressing him thus — "If thee shoots that, we'll shoot thee," succeeded in preserving the stone to fulfil its great destiny. A series of handsome busts adorns the hall of the Museum. Appropriately carved in stone are the counterfeit presentments of great geologists. An important addition to the busts of Smith, Playfair, De la Beche, Buckland, and Murchison, has recently been presented to the Museum by a generous lady. This is a magnificent marble bust of the late Professor Sedgwick, by Woolner — one of the happiest efforts of that eminent sculptor. Out of the main track of the visitor is a curious and valuable collection, illustrative of the progress of fictile industry in this country and abroad. The ceramic and vitreous series contains specimens of Bovey clay, Poole clay, China stone, and the famous Kaolin, China or Cornish clay, to the introduction of which the beauty of porcelain is mainly to be attributed. Speci- mens of raw material and of various kinds of porce- lain and pottery, in different stages of manufacture, are arranged on the symmetrical plan carried out in every other department; but, albeit proud of their THE MUSEUM OF PRACTICAL GEOLOGY. 265 lianclsome collection of china and glass, tlie courteous officers of the institution confess with sorrow that perhaps their well-meant efforts have contributed to excite the present absurd mania for crockery. The Museum is open gratuitously to the public on Mondays and Saturdays from 10 a.m. to 10 p.m., and on the other days of the week (Friday excepted) during the usual hours. There is one month of vacation, from the 10th August to the 10th September, when the Museum is entirely closed. The edifice contains a library of 15,000 volumes, devoted to the sciences taught in the School of Mines. These are available for the use of students in the School, and also, ui^on special application, stating the object in view, may be consulted by other inquirers. Taken altogether, the institution in Jermyn Street is admirable. As a " show "it is full of interest and entertainment, but considered in its more important aspect as an engine of direct instruction, it not only excites admiration at its perfect arrangement, but wonder that no greater haste is made to follow the excellent example set by the Museum of Practical Geology. 266 SCIENTIFIC LONDON. XII. THE BEITISH ASSOCIATION FOE THE ADVANCEMENT OF SCIENCE. Forasmuch as the British Association is only con- spicuous in London by its absence, and holds its meet- ings everywhere but in the metropolis, it can hardly be included under the title of " Scientific London." Still, when I reflect that much of the work of this important body is done on the banks of the Thames, and that committee meetings take place in Albemarle Street, while the great holiday gatherings are reserved for the provinces, I cannot refrain from mentioning a society of special type, which has exercised enormous influence in disseminating and fostering a natural taste for every branch of science. With the advent of the spirit of scientific investiga- tion arose the idea that while the formation of special societies would assist the development of particular branches of study, some great catholic association THE BRITISH ASSOCIATION. 267 should promote the general advance of science in this, country. For a long while this duty was fulfilled by the Koyal Society. From the collection of detached facts and observations this august body advanced at length to the pursuit of knowledge of all kinds, and accepting communications on every branch of science, . filled the important position of supreme arbiter of the scientific circles of England. But in time the limbs grew too numerous and too ponderous for the parent trunk, and were lopped off one by one. The Society of Antiquaries disposed of one class of communications, and the Linnsean Society, the Geological and Eoyal Astronomical Societies successively reduced the area of the Royal Society's work. Meanwhile scientific knowledge ad- vanced and entirely new sciences sprang into existence. At the commencement of the present century the brilliant discoveries and attractive lectures of Davy had forced from society a species of recognition, while the extraordinary development of the steam-engine, and the increasing trade in dyes and other " chemi- cals," had brought home to the commercial mind the importance of scientific knowledge. It became recog- nized that the very existence of England depends on her being second to no other nation in the prompt application of scientific discoveries and scientific method to the gigantic industries for which this little 268 SCIENTIFIC LONDON. island is celebrated. For a while the antagonistic influence of two widely separated sections of society- was severely felt. On the part of the great Univer- sities a positive dislike was shown to the introduction of science into education. At the University of Oxford, the elegant — but utterly useless — trick of composing Greek and Latin verse was considered of sufficient importance to occuj^y several of the most valuable years of a man's life; while at Cambridge — invested with scientific glory by the immortal Newton — although mathematical science enjoyed a certain prominence, its study was almost exclusively regarded as a mere training of the understanding, a species of mental gymnastics fitted to harden the logical facul- ties as practice in the eight-oar hardens and develops the muscles. As an instrument for the discovery of new truths, mathematics were entirely disregarded, and Cambridge was content to let science be where it was left by the great philosopher who described himself as a child picking up shells by the shore of the ocean of truth. Those impressed with the value of a scientific education, groaned over the Oxford graduate, whose proficiency in the dead languages was compensated by complete ignorance of the elementary principles of a telescope, a barometer, or a steam- engine, and declared that unless scientific study were made compulsory as an integral part of an university THE BRITISH ASSOCIATION. '269 education, neither Oxford nor Cambridge would ever become the scene of scientific investigation. We all now know how science has triumphed over her foes in the Universities, but it is deeply interest- ing to consider how much progress has been retarded on the other hand by the so-called "practical man." Whether a general officer or a blacksmith, the "practical man" sternly opposed any application of theoretical knowledge to his peculiar profession. The natural buU-headedness of Englishmen made the English practical man peculiarly offensive. It was often asked, " Of what use is science ? " and the head of a great military department once declared openly that he "hated scientific officers," while it was but too well known that in his own department more money had been wasted and more lives lost — from sheer ignorance of science — "than any one could think of without shame and sorrow." Another general officer — as if to justify Fielding's remarks on the military cranium — gave it as his opinion that "theoretical knowledge was not necessary in the army. An officer might be a good officer without any education at all."" In the industrial world a like feeling j)revailed. Dr. Lyon Playfair declared that the title of "practical man" was erroneously used by Englishmen to envelop their ignorance, and that reliance on the "practical or common sense of our population is the sunken '270 SCIENTIFIC LONDON. rock directly in the course both of our agriculture and manufactures." Dr. Lyon Playfair continued in the following terms: — "If England keeps pace with other countries as a manufacturing nation, it must be by her sons of industry becoming humble disciples of science. Now that the progress of human events has converted the competition of industry into a competition of intellect, it will no longer do to plume and pride ourselves on our power of mere practical adaptation. It is miserable to see our industrial population glorying in their ignorance of the principles on which their manufactures depend, and vaunting their empiricism, or, as they term it, their practice." The importance of applying the faculties of observa- tion and reasoning to the problems of nature is also proclaimed by Sir John Herschel, who says, "The abstract sciences are the concentration of what has been established as true in the operations of nature — they are so much of certainty acquired in the midst of uncertainty. When sufficiently advanced to be directly applicable to the industrial and other arts they convert the crawl of improvement into a race." Theory may, then, be defined as a species of rule of ■which practice is merely the example; but, for all that, is yet at a discount in this country, where people love to ignore their obligations to such " theorists " as THE BRITISH ASSOCIATION. 271 Newton, Watt, Stephen Gray, and Davy, and to exalt to the skies the ''practical men" who blundered and muddled on for thousands of years without achieving any great improvement, and would probably have gone on stumbling for ever had not the gloomy regions of practice been illumined by the light of theory. The influence of the numerous learned societies in encouraging observation and diffusing a philosophical spirit, the efforts of the Eoyal Society to excite interest in purely scientific subjects, and the excellent work done by the Society of Arts in showing the intimate connection between science and industry, failed to secure national appreciation until steam communica- tion and the rapid transmission of news by degrees made men aware of the enormous losses of life and property annually suffered from sheer want of scientific knowledge. Pending the more general appreciation of the advantages of scientific culture, a discussion arose, between the years 1826 and 1831, on the low state of science and scientific men in England. To Sir David Brewster is undoubtedly due the origin of the British Association, but the original con- ception of a Scientific Parliament is purely German, and was simply imported into this country by the great northern philosopher. In 1822 Dr. Oken, of Munich, originated the idea of an annual congress of scientific men, with the object of bringing them into personal 272 SCIENTIFIC LONDON. contact. The first meeting was held at Leipzig, and was attended by only thirty-two persons, of whom twenty were resident in the city. The meetings, how- ever, rapidly increased in importance. That of 1827, held in Mmiich, was warmly patronised by the King^ of Bavaria, and in the following year the philosophers assembled at Berlin, on which occasion they were warmly welcomed by the King and presided over by the illustrious Von Humboldt. Babbage was the only Englishman present, and communicated an interesting account of the Scientific Congress to the Edinhurgh Journal of Science. Intelligent foreigners had long remarked the slender estimation in which science and its votaries were held in England, and by the efforts of Sir Humphry Davy,. Sir John Herschel, Sir David Brewster, and others, the upper stratum of national feeling was stirred up. It was set forth that foreign scientific institutions were greatly superior to those in existence in England, and the decline of scientific studies among the aristocracy was vigorously pointed out by Davy, who remarked that, *'in looking back to the history of the last five reigns in England, we find Boyles, Cavendishes, and Howards, who rendered their great names more illustrious by their scientific renown, but we may in vain search the aristocracy now for philosophers ; and there are very few persons who pursue science with true dignity ; it THE BRITISH ASSOCIATION. 273 is followed more as connected with objects of profit than those of fame, and there are fifty persons who take out patents for supjDOsed inventions for one who ^ makes a real discovery." In like spirit, Babbage exposed the prevailing ignorance of the more difficult and abstract sciences, and declared that mathematics and, with it, the highest departments of physical science had gradually declined since the days of Newton. These shortcomings were attributed to the abuses then existing in the management of our scientific institutions — the imperfect system of in- struction in public schools and universities — the ignorance of public men — and the culpable indiffer- ence of successive Governments to the intellectual glory of the country. Babbage' s onslaught was supported by Sir David Brewster, who, in the Quarterly Revieir, drew a comparison between the existing state of science at home and abroad, very much to the dis- advantage of England. At the conclusion of this important article, the writer — whose philosophic in- vestigations had extended through every branch of physical science — mentioned the best method for reviving and extending science in the British Islands: — ''An Association of our nobility, clergy, gentry, and philosophers can alone draw the attention of the Sovereign and the nation to this blot upon its fame." In 1831, through the instrumentality of Lord 274 SCIENTIFIC LONDON. Brougliam, the state of science and its followers was brought before Lord Grey's Government, and some important objects relative to the Association suggested by Sir David Brewster were secured. Early in 1831 Sir David Brewster set vigorously to work to establish a British Association of Men of Science, similar to that which had existed for eight years in Germany. The principal objects of the Society were to make the cultivators of science famiHar with each other, to stimulate one another to new exertions, to bring the objects of science before the public eye, and to take measures for advancing its interests and accelerating its progress. York was selected by Sir David Brewster as the locality for the first meeting, on the ground of its being a central town already provided with a Philosophical Society of its own. The local philosophers as well as the mayor and magistrates of York took up the project heartily, and the first meeting was attended by more than three hundred persons, who responded to the invita- tions issued by the Yorkshire Philosophical Society. Prominent among the organizers of the movement were Sir Eoderick Murchison, Professor Phillips, and Eev. W. Vernon Harcourt in London, and Messrs. Eobinson, Johnston, and Forbes in Edinburgh, while the learned and venerable Archbishop of York entered warmly and hospitably into the scheme. Under the THE BRITISH ASSOCIATION. 275 presidency of Lord Milton the inaugural meeting was held at the Museum of the York Philosophical Society, the British Association was duly organized; and so well was the important task of planning and arranging performed that few variations have been made from the original sketch. Thoroughly maintaining the idea of catholicity, the British Association contemplates no interference with the ground occupied by other institutions. Briefly stated its objects are: — To give a stronger impulse and a more systematic direction to scientific inquiry — to promote the intercourse of those who cultivate science in different parts of the British Empire with one another and with foreign philosophers — to obtain a more general attention to the objects of science, and a removal of any disadvantages of a public kind which impede its progess. The Association meets annually for at least one week in some town decided upon two years in advance. During the forty-three years of its existence the members of the Association have indeed seen men and cities. Not only the great commercial centres of the kingdom, but seats of learning and fashionable watering-places have been visited. Thus Oxford, Dublin, Liverpool, York, Cam- bridge, Bath, Glasgow and Cheltenham, Brighton and Bradford, have in turn welcomed the British Associa- tion. On the occasion of these visits ample prepara- 276 SCIENTIFIC LONDON. tions are made by the local authorities, and much hospitality dispensed. At Bradford last year, for instance, the city expended some i£3,000 in receiving and entertaining the philosophers. After the general meeting, at which the president- elect delivers an address, the general committee takes the business of the meeting in hand, while particular departments are discussed in the sections by special committees. The sections into which the business of the British Association is divided are — A. Mathe- matical and Physical Science. B. Chemical Science. C. Geology. D. Biology — subdivided into three depart^ ments — Anatomy and Physiology — Zoology and Botany — Anthroj)ology. E. Geography. F. Economic Science and Statistics. G. Mechanical Science. In these sections the proceedings of the jprevious annual meeting, the recommendations adopted there, and the action since taken upon them, are reviewed.. Suggestions are also made by the members, and definite points of research to which individual or combined exertion may be usefully directed, are care- fully selected after due discussion. Many interesting papers are read, and of these the most interesting are published in extenso in the annual report, while those of less importance receive the slighter honour of an extract. During the annual celebration two evenings are THE BRITISH ASSOCIATION. 277
