REGIUS PROFESSOR OF PHYSIC IN THE UNIVERSITY OF CAMBRIDGE FELLOW OF GONVILLE AND CAIUS COLLEGE, HON. FELLOW ROYAL COLLEGE OF PHYSICIANS OF IRELAND !LonlJ0n MACMILLAN AND CO., Limited NEW YORK ; THE MACMILLAN COMPANY 1904 'T All rights resej ved PKEFACE In the course of the year I peruse sixty or seventy theses for the degree of M.B. and about twenty- five for the degree of M.D. The matter of these theses is good, it is often excellent ; in composition a few are good, but the greater number are written badly, some very ill indeed. The prevailing defect of their composition is not mere inelegance ; were it so, it were unworthy of educated men : it is such as to obscure, to perplex, and even to hide or to travesty the sense itself. Thus, for the judge who would be just, many of the theses are very hard reading ; and, meritorious as in substance they may be, are, as they stand, unfit for the printer. The use of thesis -writing is to train the mind, or to prove that the mind has been trained ; the former purpose is, I trust, promoted, the evidences of the latter are scanty and occasional. Thus, when the Act is kept, we are often forced, against our desire, to dwell on faults of form to some exclusion of the argument. It seemed to me, therefore, that if. vi SCIENTIFIC PAPERS by a collection of the commoner errors and defects, once for all I were deceived in my hope of bringing about some reformation of the essays, I might at any rate so economise my censures of the manner as to devote myself in future to the matter only. I fondly supposed that these criticisms of form might be put together for the press, as an open letter, in a few afternoons : I was sadly deceived. The task proved to be far heavier than I had anticipated. Moreover, for the humble duty I set before myself I had made no special preparation; I had read no grammars, nor the handbooks of literary artists. The treatise of Mr. Miles on Essay-writing appeared "before my manuscript was finished, but by a mischance his volume — though kindly dedicated to me — had failed to reach me. Mr. Cornford's book appeared after my little work was done. Yet I am glad I did not see these books, or others of the kind, lest at the begin- ning I might have been tempted by such bright examples far out of my narrower way. The books of Mr. Miles and of Mr. Cornford are systematic and constructive, they survey the field and the methods of authorship ; my hints, if, as I trust, they have some organic unity, are but comments on the more frequent or the more eminent defects of scientific essays, and are as unsystematic and occasional as the defects themselves. I have ob- served no scheme or proportions in my parts but PREFACE vii those of the faults and errors after which they are designed. With the stuff of which theses are to he made I have not concerned myself; for scientific papers the kind of subject and the stuff are preordained. If, as Mr. Cornford tells us, teachers and examiners of the day are demanding essays not, as ours are, on the rough and homely materials of common work, but on the sublimer qualities of life, on Eloquence, Enthusiasm, Courtesy, Thoroughness, Patriotism, Drama, Travel, Education, Sympathy, Wit and Humour, Eminence of Great Men, All is Vanity, and the like — themes I have gleaned from his book, if these issues of rich fancy and ripened experi- ence are required of schoolboys and undergraduates, it is well that they have Mr. Miles and Mr. Corn- ford to teach them the cunning of it all, and to " open yet another career for dulness." One day in my remote past I was set to create such an essay on my slate while my governess went out to tea : Death was the subject she thought appropriate for my handling. After much gasping in the vacuity of my mind, in which was neither straw nor clay, I became so fatigued as to be beset by the hand- some word " erroneous " which that morning I had admired in the mouth of one of my elders. Surely this word made itself inevitable ; and on her return my governess perused this brief but I venture to think not unsuccessful little essay : " Death is an viii SCIENTIFIC PAPEES erroneous circumstance.'' I publish it now for the first time, as both for form and substance Mr. Cornford's disciples may find it a useful pattern in the art of " painting shadows in imaginary lines." In obedience to a general desire I have divested these critical notes of the peculiarly medical features which they had at first; while preserving their immediate purpose, I have exchanged many of my medical instances for others of a pleasanter kind ; nevertheless this tract is intended chiefly for my own students, and is chiefly concerned therefore not with letters as a whole but with so much of the form and correctness of scientific papers as my experience tells me is perverted or neglected by their authors. My quotations are given for the most part without acknowledgment ; for obvious reasons. CONTENTS CHAPTEE I PAGE Inteoductoky .... ... 1 Fashion of academic essays, 1. Their purpose, 2.

IX CHAPTEE I INTRODUCTORY It is in no desire to curtail my conversation with candidates for degrees in Medicine that I publish a few notes or hints on the composition of scientific papers. The larger conditions of method and material cannot be reduced to notes ; they will always be with us for counsel and inquiry : but there are many conditions in the economy of argument, in the handling of common knowledge and ideas, in the use of authority, in the forms and aids of expression, which must be observed in all exercises of the kind. My present purpose is to instruct the candidate on minor points, that he may be spared the smaller corrections which occupy some of the time and pains which are better spent upon the weightier contents of theses submitted for the Acts for M.B. and M.D. degrees, and of other academic essays. It is one of the duties of a University to give instruction, and much of its instruction may be tested by suitably devised exercises, even by some kinds of examination ; but it is our higher B 2 SCIENTIFIC PAPEES chap. function to teach our students to think, and of this accomplishment the thesis or essay is the chief evidence. Thus it is that the Faculty of Medicine in Cambridge regards the theses as necessary parts of the exercises for degrees ; their use being two- fold : to train the mind, and to show how far it has been trained. The theses for M.B. are on the whole remarkably good ; some of them indeed reveal no inconsiderable power of thought and research : if at this stage, however, we are content with a fair measure of industry and intelligence, from the candidate for M.D. or D.Sc, for a Fellow- ship or Studentship, for one of the larger University prizes, or for the graduation of an 'Advanced Student,' more is expected ; from such a candidate we expect some maturity of thought, some wealth of personal experience, something of the art of putting his thoughts ; and indeed some originality. He must have made the subject his own ; his treatment of it must bear the characters of personal observation and reflexion which raise an essay above the level of ordinary compilation, and the powers of handling ideas and principles which distinguish, or should distinguish, University train- ing as contrasted with technical instruction. "A man," says Sir Thomas Browne, " should be some- thing that all men are not, and individual in some- what beside his proper name." If in such essays we find the cardinal qualities, we are lenient in respect of some slovenliness of arrangement, or some inaccuracy of language, unbecoming as such faults may be. I INTEODUCTOEY 3 That we do not always succeed in teaching the student to think is but too evident in his bewilderment when he has to find a subject for an essay. Now, it is true that the proper choice of, a subject is a difficult matter, one in which few candidates can be independent of the assistance of their elders ; yet too often the student is bewil- dered, not in his choice of one among the infinite number of subjects calling for inquiry, but in his contentment with current formulas, in his lack of perception of the immaturity of our science, the hoUowness of much of our knowledge, and the solidity of much of our ignorance. Students who have attended my lectures may remember that I try not only to teach them what we know, but also to realise how little this is : in every direction we seem to travel but a very short way before we are brought to a stop ; our eyes are opened to see that our path is beset with doubts, and that even our best-made knowledge comes but too soon to an end. In every chapter arises problem after problem to beckon us on to farther investigation ; yet this way and that we are so baffled by darkness and ignorance that to choose one of these problems for attack, one which is likely to repay his labour, is often beyond the scope of a junior candi- date, of a candidate for the degree of M.B. for example ; and it is not easy for me to help him, as I may help a candidate for M.D, The subject for M.B. and like junior exercises must be comparatively simple, the materials easily accessible, and the research straightforward. In 4 SCIENTIFIC PAPEES chap. my own department, therefore, I usually advise the M.B. candidate to consult a member of the staff of his hospital, who will help him to some inquiry for which, in the current clinical or patho- logical work of the school, material happens to be at hand. I have gratefully to acknowledge the advice and guidance afforded to Cambridge students, in the preparation of their theses, by members of the staffs of large hospitals and laboratories elsewhere. For M.B. I accept subjects from any department of Medicine, including surgery and obstetrics ; for M.D. topics definitely surgical, being proper rather for the M.C., are avoided. In the course of the last few months of his work for the final examinations, the M.B. candidate will do well to ponder over two or three subjects ; so that, the examination over, he may obtain ap- proval of that one which seems most convenient, and set to work upon it without delay ; thus in a few weeks his thesis may be completed. Some candidates get the subject approved and the work well forward before the final examination ; so that by a successful candidate the Act may be kept forthwith. If the thesis be not ready, the degree of B.C., which is a ' double qualification,' can be taken, and registered ; and the M.B. postponed till the Act can be kept. For advanced students, such as the candidate for M.D., the undertaking is not so simple ; such persons must enter upon a larger research, and one less dependent upon ordinary advantages : indeed, if out of residence, the candidate may have to I INTEODUCTOEY 5 make his opportunities. Scientific methods — bio- logical, chemical, or physical — are becoming longer and stricter ; and, unless other occupation can be set aside, a year's work may scarcely suffice for the completion of a thesis. Hence it is of greater importance that the advanced student should be careful to select a fruitful subject, and to pursue it from the first on a right method. On these larger undertakings the advice of the Eegius Professor and of teachers of special subjects in the University and other schools is more available. For a candidate for M.D. who has entered into general practice, and who may have given such hostages to fortune that he must devote the best of his time to earning an income, the preparation of a thesis is not impossible ; but it is difficult. Half-hours he would willingly give to rest must be devoted to work ; methods of research, readUy undertaken in a laboratory or clinical school, are now a heavy tax upon his ingenuity and his purse ; processes which need continuous attention can hardly be carried forward; libraries may be far away, and apparatus costly or out of reach. Yet, in spite of such hardships, every now and then a candidate for M.D. emerges from general practice with a thesis which is but the more excellent for the self-denial and the high purpose which inspired it. Of late years, however, I have reminded graduates who intend to enter general practice, and yet would merit the M.D. degree, to proceed to these exercises as soon as the M.B. is attained — during, we may suppose, the tenure of some hospital 6 SCIENTIFIC PAPEKS chap. or laboratory appointment. We are willing to read theses and, in case of acceptance, to take the Act for M.D. at any date after M.B- ; though of course the degree cannot be conferred till the due period is fulfilled. If, however, after his M.B. degree the candidate must enter upon general practice without delay, and yet would aim at the M.D., I advise him to make some notes, however brief, of every case, however trivial ; to supply himself with some instruments of precision, according to his tastes and aptitudes ; and for a few years to content himself with gathering clinical and other material, and keep- ing up his reading : thus in time a subject may shape itself in his mind. I heard it said lately of a very able physician in country practice that for thirty years he had scarcely ever failed to obtain a necropsy in his fatal cases. It is sad to think that the wisdom of an observer, so earnest as he must have been, should have died with him ; what a thesis he might have written ! Twice or thrice we have received from physicians in country places a nosological survey of a certain district ; the nature and incidence of disease being compared with the local peculiarities and variations of climate, soil, social habits, and the like. Prom the time of White of Selborne it has been the good custom of naturalists and antiquaries thus to examine the features and relics of particular places ; by com- bining the records of many such observers we might in time put together a medical survey of the kingdom. Title of a thesis. — From the title sent up for approval I am often able to form some notion of I INTEODUCTOEY 7 the composition which will follow. A concise and pointed title preludes similar virtues in the essay ; a weak or diffuse title, on the other hand, fore- shadows a loose and vague argument. Or a title may be concise enough, yet not to the point; e.g. a candidate may suggest to me 'Three Cases of Pernicious Anaemia.' This title suggests no more than a report of the notes of the three cases ; whereas the writer is probably aware that a mere collection of cases in any number, without com- parison and argument, is unacceptable. Many titles, again, which give the indications of the argument well enough, are designed to comprehend too much, more than is necessary to denote the subject; or are too heavily loaded with technical terms. First impressions are strong impressions ; a title ought therefore to be well studied, and to give, so far as its limits permit, a precise indication of what is to come. After the title the writer may contemplate some definitions : but he will do well, especially in biology, to distinguish between technical, verbal, or historical definitions and attempts to define natural kinds. Even in astronomy to define a constellation would be no easy business ; and, as the departments of science become more and more complex, definition is recognised as a scholastical task which makes for sterility. Classes we must create artificially, for the convenience of thinking ; and of such classes we must give short descriptions : but we shall beware of taking short descriptions for definitions. On precision of thinking I cannot say too much, but to pack samples of thought in hard shells is to bury 8 SCIENTIFIC PAPEES chap. thought alive. We must beware of taking pro- visional for radical distinctions. Form. — The subject chosen, facts must be collected, inferences formulated, and the whole presented with due proportion in its several parts, and in language as nervous and lucid as the author can command. But, as strength and general dexterity do not suffice to make a cricketer, so knowledge and mental power do not suffice to make a writer. No one feels vexed that he cannot dance, paint, or ride to hounds without practice ; jet men are apt to murmur that it is but the mere knack of writing, a knack with which, according to them and to Dogberry, some fellows are endowed by nature, which is wanting to make their learning and talents conspicuous. To those who have taken lifelong thought how to write, who have striven painfully with the craft of this supreme art, the view of it as a happy gift seems a flippancy. In critical jargon, indeed, the happiest word or phrase is called ' inevitable,' but it becomes inevitable when we have seen it ; till then it is but too evitable. Let the candidate be assured that an easy and interesting style, like easy cricket, implies hard practice ; the prose which in Swift, in Newman, in Proude, in Thackeray, runs so transparently that, to him whose eye is not set for it, the medium is unseen, comes of patience as enduring and training as exquisite as the more effulgent phrase of Sir Thomas Browne, Professor Euskin, or De Quincey. No pieces are more ' spontaneous ' than the Fables of La Fontaine, but the labour of correction and I INTEODUCTOEY 9 revision which he gave to them seems to us almost incredible. Butfon, we are told, rewrote his prose twelve or fourteen times, and then would have it read aloud to him, that he might note where the reader hesitated. Gautier wrote at terrific speed, and, it is said, never revised. What is the consequence? Time has found out that his brilliant fantastic work has no solidity : that it is flamboyant, loaded, disorderly; and will not endure. To me, the most of whose work is done away from the desk, composition is painful; to few men busy in affairs can it be otherwise than painful : yet the man of science ought best to know that style and matter can no more be dissociated than skin and bone ; that if we write clumsily, loosely, or disjointedly our thoughts are accord- ingly. In scientific prose words should be used as carefully as symbols in mathematics ; there are few true synonyms in literature, none perhaps : words have not only their stem meanings, but carry upon them also many changes and tinctures of past uses which blend inevitably in our sentences. The word ' apostate,' for example, means far more than an absentee or a dissenter, and a muscle more than a little mouse ; monks rarely live alone ; your anecdote is anything but clandestine ; rivals con- tend for other than water rights, and hypocrites are no longer confined to the theatre (p. 85). Yet no accomplished writer forgets the traditions of words, nor the incidental connotations thus clinging to them ; nor that it is due to these evanescent features that, large as the common elements of two 10 SCIENTIFIC PAPERS chap. words may be, no two are strictly synonymous. "When to this we add the "genius of a whole language," we shall comprehend that even if trans- lation of a work from one tongue into another may issue in a finer work of art, the pieces can never be even approximately identical. To trans- late prjropeia, ineptus, humanitas, or Dichtung, is indeed impossible ; and to translate citUi into city is an illustrative blunder. We have, then, to choose our words not only as we should choose mathematical symbols, or the parts of a diagram, but also as we should lay in tints for a picture, or mix quarries for a painted window. We shall be ashamed of the beggarly vocabularies {vide p. 89) which seem to satisfy most essayists ; and not occupying our- selves with the flimsy and slatternly wares of the railway bookstalls but with the masters of prose, of our own time and of all time, we shall furnish j our memories with a richer store of words and thoughts, and, by weighing and comparing them, educate our sense of their relative values. In sketching the plan of a work, be it small or great, one of the first questions to put to our- selves is — For what readers is my treatise, paper, or pamphlet intended ? This question we often fail to keep vividly before ourselves : we are apt to forget whom we are addressing; whether simple readers, learned readers, advanced students, a section of the public, or the general public. When full of his subject, an author may soar away from the apt and the convenient, and write so at large that the essay comes home to no one : for some it is I INTEODUCTOEY 11 too much, for others too little, for others useless or alien. Every writer has his own method of com- posing ; I will describe that which I have found to answer well enough. Por each subject on which T may have to write, I set apart a labelled drawer, or a large quarto envelope, and into it I throw the proper cuttings, slips, and references to books or papers. It is better to copy extracts at the time of discovery than, when at work, to have to fetch them, it may be from a distant library. Extracts and summaries in Year-books, and the like, must be accepted with caution ; often they pervert the meaning, or are false to the context of the original essay. My slips are of the size of cheques, that is about eight inches by three ; two inches of one end are left blank. I never make two entries on one slip, nor write on both sides of any. When I begin to write, these slips may have accumulated for years, and the first work is to parcel the subject into its several chapters, and to write the titles and numbers of these on similar slips of stouter paper. Next, having fixed a ' bulldog clip ' upon each of these capital slips, I distribute under them the minor slips proper to each. The blank ends of the slips pass under the clip, so that no writing is concealed ; and thus secured the slips are as easily fumbled as the leaves of a cheque-book. During this part of the work changes in the chapters, or in the number or order of them, often suggest them- selves ; some need division, some are merged in others. 12 SCIENTIFIC PAPEES chap. The next task is to arrange the slips within each clip in logical order, when many obsolete notes are destroyed, others are blended and rewritten. From the slips thus arranged I write a hasty iirst draft of the article. I do not destroy each slip as it is used, but I draw a line across it and store it, lest it be wanted again. Eound three sides of the manuscript a wide margin is left. The work may now be regarded as half done ; I usually make four drafts at least before the manuscript is ready for the printer. For the second draft I delete redundant words, phrases, sentences, and paragraphs; by doing this rigorously, and pulling the rest together, from one-sixth to one-fifth of this manuscript, or even more of it, disappears. Many sentences are but repetitions ; others are got rid of by the insertion elsewhere of a minor claiise, or of an adjective ; thus : — Other factors, such as rickets or tuberculosis, must be taken into account, as any one of these will have an adverse influence on the case. Here ' adverse ' should be inserted before ' factors,' and the sentence ended at ' account.' Eemeniber the defence of a prolix report :^—" I hadn't time to make it shorter." Transfers also are made now ; sentences and paragraphs which would stand better elsewhere are translated. Again, excogitate matter and argument as we may before beginning to write, yet, as we write, thought develops, and may de- velop considerably ; so the later part of the first draft proceeds on larger lines, and is fuller in 1 INTEODUCTOEY 13 thought than the earlier part. In the second draft, therefore, the writer has to consider the earlier part iu the light of the later, and has to remodel the narrower conception of this part on the hroader con- ception proper to the whole. This is the toughest of the tasks of revision, for it may be necessary to break up and reconstruct the piece. As this first reading proceeds an index is easily jotted down ; if the work needs no index the list is nevertheless very convenient in making later insertions and corrections, and in detection of repetitions. On the third draft the composition is submitted to a still closer revision ; but the main work of this stage is to recast paragraphs and sentences till they run logically, and bear but one meaning, and this inevitably: perverse constructions and equivocal or defective words give way to their betters. Ornamental and figurative passages also undergo purgation : in scientific papers purgation should generally go to expurgation; yet our writing should be lively as well as true, and some happy allusions, if distilled to their essence, may be carried in upon an adjective, or upon a noun coloured by an apt association. An author should form the habit of setting down no word, not even the definite article, without weighing, less and less consciously as his habit grows, its primary meaning, its derivative meanings, and its colour in the particular context. From instant to instant he will turn each word over as shrewdly as a thrush turns a pebble. An intelligent friend of mine once exclaimed, " You don't mean to say one has to think on every word before one puts it 14 SCIENTIFIC PAPEES chap. down ? " Certainly ; but by habit these apprecia- tions become automatic, as swift judgment iu a game or the mazy dance of a lacemaker's bobbins becomes automatic. When a distinguished physi- cian proclaimed to us the other day without quali- fication that " The number of the infectious diseases is by no means complete," he had not formed this habit ; for we may hope that he meant no more than our discrimination of such as we have. If the writer has endeavoured to enrich his vocabulary, he will find that by the wider choice of words he will gain in truth as well as in liveli- ness ; his expressions will become more and more apt ; he will know, for instance, when to say ' begin,' when to say ' commence ' ; when to say ' theory,' when to say ' opinion,' ' notion,' ' conjecture,' or ' guess.' Or a sentence may be stuffed, like a bag, with valuable matter ; yet unless the clauses run in the order of the thought, and by still subtler arrangement emphasise its main points and posi- tions, the reader's attention will flag. Not only the clauses, then, but the words also must be placed exactly (p. 79) ; for emphasis, like a ' call ' at whist, may be given by slight transpositions, even of single words (p. 127). It is deplorable that most writers, by ignoring the order of words and clauses, obfus- cate their own meanings, blunt our insight into thought, and make for listlessness both in author and reader. Before the final revision let some considerable time intervene — ^ say a week or two at least ; in order that meanwhile the mind may meditate I INTEODUCTOEY 15 subconsciously on the subject, and that the final reading be done' with refreshed attention ; it is surprising with what new critical and constructive interest one conies again to a subject and to a manuscript which for a while have been laid aside. Moreover, before undertaking a critical re-perusal, provide for some leisure, so as to read not by bits, but over a good stretch of the manuscript at once, and to attain a large survey of its scope and bear- ings. Never compose when tired, nor in the false confidence of tea and late hours. At this hour the composition seems to be beautiful and spontaneous ; but it is fairy gold, in the colder light of the morning it turns to ashes. The logic of an essay. — Speaking generally, it is better to compose a scientific essay, and to construct its limbs, not on the inductive plan on which the research was pursued, but deductively. In investigation we step first upon the bottom facts ; then we make short inferences, and test them by more facts ; these inferences widen and widen, and in their turns are tested, and so on ; such is the course of research : but as demonstration the system is not telling; the student is held too long in suspense (vide p. 59). This sentence I borrow from another use, as it may serve briefly to illustrate this advice : — The Presbyterians threw their freedom down without casting one glance on the past at the feet of the most heart- less tyrant. This is the order in which the thought may well 16 SCIENTIFIC PAPEES chap. have arisen in the excogitation. But we shall see how much better it is to alter the order of ex- cogitation, and by a new synthesis to carry back ' without casting one glance at the past ' to the beginning. It is better to begin, then, by setting forth certain more general views; and from these to proceed to closer and closer quarters with the particulars on which our position is to be estab- lished. Logic does not make matter, it arranges matter already gathered. I sometimes waste time in the futile wish that Epicurus' word ' Canonic ' had superseded ' Logic ' ; for, clear our minds as we may. Logos does no doubt suggest the essence of things ; but ' Canonic ' suggests no more than rules of thought. Logic has always sought to " go into the merits " wherein it has no business to meddle. Logic is not all, nor nearly all. La logique mkie aux ahimes. Language, like good manners, owes not its charm only but also its force and pene- tration to incalculable, imponderable elements. The line of the dryest argument overflows logic in all directions, reason turns and doubles on itself; were it possible to photograph it in a flash, its course would appear not as a straight line, but as one of curves and zigzags ; thus as it goes it falls under changing lights, and intimate metaphors creep in even unbidden. Moreover, an author cannot but be aware of his audience; he receives its influence into his fancy, and betrays his wariness by glances and stage asides. In the following sentence, plain as it is, we may note prospects opened and passed in flashes, quick doubles, and glints striking hither I INTEODUCTOEY 17 and thither. Note the telling aside to the reader in the one ironical word ' usurping ' : — A lay-papist will first consider his abbey-lands ; . . . if zeal get the better of the law ... his new humble con- fessor may be raised to a bishoprick, and from thence look down superciliously upon his patron, or which is worse, run to take possession for God Almighty of his abbey, in such manner as the usurping landlord shall hardly be admitted to be so much as a tenant to his own lands. Again, in its tones and rhythms language plays upon us as the instrument of a musician (p. 137); heyond its melodies and its scores, it is attuned to us in an infinite sphere of ' wireless ' vibrations, born partly of its own fibre, partly of the fibre of the master; these harmonies obey no formal call, and defy all reckonings. Whether, then, we decide to arrange our matter inductively or deductively, the place of logic, or ' canonic,' is to see that the order and development of thought are followed precisely from step to step. As human minds are substantially alike, if the writer observes the best order of his own thought, the reader will take his line quickly and, for assent or dissent, perceive his drift. Summaries. — On the completion of a long thesis, or important scientific essay, it is well to draw up a syllabus of the argument and to place it at the beginning ; in any case let the conclusions be resumed succinctly at the end : it is not for the author to compel the reader to peruse his essay. For students whose essays approach the field of letters an interesting discourse might be written c 18 SCIENTIFIC PAPEES chap. on the beginnings and ends of hooks and essays. Of ends authors of theses, and others, seem to be too careless ; yet how telling a place is the end of a paper for a weighty reflexion, or summary view of the field. All writers, however, even the least skilful, are, in the degree of their skill, at some care how to begin. An unpractised writer, for sheer helplessness at the outset, may never begin ; he may abandon his work in despair. A witty beginning is something of a liberty ; for an emphatic beginning the reader is not yet attuned ; nor is he attuned to a ponderous introduction. To begin naturally and interestingly is no mean art. I was ever of opinion that the honest man who married and brought up a large family did more service than he who continued single and only talked of population. Thus begins the Vicar of Wakefield, and what could be happier ? The opening sentence touches the heart of the story ; it is sententious, but its senti- ment is instantly lightened by a ray of humour. Again : As I walked through the wilderness of this world I lighted on a certain place where was a Denn ; and I laid me down in that place to sleep : and as I slept I dreamed a Dream. Here again the heart of the story is touched; and by the wilderness and the dream we are carried at once into the realm of the imagination. The opening chapter of The Antiquary is well known, I trust, to every one. Miss Austen's stories all open well ; e.g. — I INTRODUCTOEY 19 No one who had ever seen Catherine Morland in her infancy would have supposed her born to be an heroine ; and so on. These are indeed romantic instances ; still, if we turn to scientific works, we shall find in the eminent of them the like art of beginning happily. The Essay on Human Understanding com- mences thus : Since it is the understanding that sets man above the rest of sensible beings, and gives him all the advantage and dominion which he has over them, it is certainly a subject, even for its nobleness, worth our labour to inquire into. The Decline and Fall of the Boman Empire com- mences with a short sentence : In the second century of the Christian Aera, the empire of Rome comprehended the fairest part of the earth, and the most civilised portion of mankind. Herschel begins the Preliminary/ Discourse with like propriety, if not with like distinction : The situation of man on the globe he inhabits, and over which he has obtained the control, is in many respects exceedingly remarkable. To turn from books to essays : Macaulay does not begin admirably ; he opens mouth like a watch -dog. Matthew Arnold is happier, as in the well-known opening of his essay on Keats : Poetry, according to Milton's famous saying, should be ' simple, sensuous, impassioned.' No one can question the eminence/ in Keats's poetry of the quality/ of sensuousness. Here, in spite of the three y's, a fitting and lofty 20 SCIENTIFIC PAPEES chap. note is struck at the outset. Or, opening by chance a volume of his Causeries, I may translate the first sentence of Sainte-Beuve's essay on Jouffroy : There is a generation which, born quite at the end of the last century, still in its infancy or immaturity under the Empire, came of age, and put on the robe of manhood in the midst of the storms of 1814 and 1815. A fine opening by contrast to a study of that placid and limpid intelligence. All Bacon's essays open well, some magnificently. But I may not multiply examples ; these will suggest to us how to open a subject aptly, intimately, and also with dignity or vivacity. "We shall not begin with a crude or heavy lump of our matter, yet we shall try to touch the keynote of the subject, and to engage in the argument easily but directly. We have seen that the ' beginnings ' of great writers are direct ; we shall not begin, then, with apologies, with wayward or fanciful approaches, nor with any kind of skirmishing. After these great examples, we shall try to give first some glimpse into the heart of the matter, to put the reader at our point of view, and then to lead him briskly into the subject. Hence the beginning is not to be written until we have so cast our argument that we can perceive the exact place whence the best glimpse of its purport is to be had. We may encourage those essayists who may fall so shy of the beginning as never to enter upon their work at all, by assuring them that it is not necessary to begin their essay till they have ended it. I INTEODUCTOEY 21 Of ends I will only say, " Do not end anyhow " ; let your leave-taking be easy, gracious, and impressive in proportion to the theme ; not ponderous, pompous, epigrammatic, or austere. From a fine writer, one from whose works I might cull many admirable features, I will venture to quote the end of a book : And this age of ours, if, like its predecessors, it can boast of something of which it is proud, would, could it read the future, doubtless find also miich of which it would be ashamed. A true, but rather unkind farewell ! A charming essay by another hand ends with the reflexion that the ' argument in which we have been engaged is not addressed to all men . . .' but, in short, to the initiated reader. This is too fastidious a farewell ; even querulous perhaps. After turning over a few scientific books lying near me in search of happier ends, I translate this from Daremberg's History of the Medical Sciences : That which to-day makes the strength of the medical sciences, which assures their future destiny, is, if we reflect upon tradition and history, that all savants worthy of the name, from one end of the civilised world to the other, put- ting aside the rivalries of system, and shaking the dominion of routine authority whencesoever it may derive, seek each other and meet on the common ground of observation, experiment, and freedom of thought. For literary essayists the end of Mackail's Zatin Literature may serve as an example : In the stately structure of that imperial language they embodied those qualities which make the Roman name most abidingly great — honour, temperate wisdom, humanity, 2'A SCIENTIFIC PAPEES chap. courtesy, magnanimity ; and the civilised world still returns to that fountain-head, and finds a second mother-tongue in the speech of Cicero and Virgil. And, for my own sake, let me add the end of Colet's Accidence, surely one of the most touching farewells in literature : Wherfore I praye you, al lytel babys, al lytel chyldren, lerne gladly. . . . Trustyng of this begynnyng that ye shal procede and growe to parfyt lyterature, and come at the last to be grete clarkes. And lyfte up your lytel whyte handes for me, whiche prayeth for you to God : to whom be all honour and glory. . . . Amen {Lupton's Life, p. 177). These are notable examples ; ordinary papers and short treatises must end in modest proportion to their contents. References. — After the summary of conclusions append a sufficient list of the books and papers consulted during the research : those which the author has personally consulted in the original, howsoever he were directed thither, he may enter as his own references ; when he has not gone himself to the source, he must enter and duly attribute the reference as a quotation. The writer who learns to verify his references will learn also the curious lesson that various readers see various meanings in the same words, or context ; a con- fusion due, in some part no doubt, to ambiguities of expression. Not infrequently in the fourth draft of the essay such rehandling will suggest itself that another and yet another copy has to be made for the printer. Mr. Bryce tells i»s that Green made ten drafts of I INTEODUCTOEY 23 the first chapter of Tlie Making of England; Green who, of full and accurate writers, was one of the swiftest whose methods are known to us. Dictation. — Many authors dictate their matter to a shorthand writer, who makes a fair copy for the author's revision. Personally I find this method very defective ; and I fancy I note in other authors the defects of it. It saves much trouble, there is no doubt; and for temporary purposes, especially for addresses to be spoken, it is convenient. But the language of literature, both in scope and variety, is very different from that of conversation. As I was writing a sentence on a previous page of this essay I lacked a certain word, and the word did not come to me till the afternoon of the following day : what about the typewriter's patience ? We do not always realise how lean and cursory a discourse may appear on the printed page which in conversation or public speech was telling enough. To write prattle, save for some light and ephemeral purpose, is as inept as to talk like a book. If the reader conceives that the felicitous narrative, or gossipy prose of Sterne, Elia, or Thackeray is but written talk, let him read a page or two, close the book, and try to reproduce it. In such prose the impression of unstudied ease is a product of the finest pains, of pains unknown to those who are prepared with the stuff but not with the art of letters {vide p. 63). Anyhow will do ! — ^But the ' practical man ' will say that these are trivial or ingenious in- ventions ; why all this torment of form if in any shape he can shovel the stuff he has to dispose of 24 SCIENTIFIC PAPEES chap. into the reader's head ? Well, in the first place a writer who writes to convince, and not merely to see his name in print, must learn to lay his mind alongside that of the reader. The reader must be carried along in a quick and equable current. It vexes him to have to return upon sentence after sentence in order to revise the author's particular meanings by the general tenor of his argument ; yet in reading current prose this vexation is so continual that we scarcely realise the burden and tax of it. A sentence, as it stands, bears a certain meaning ; the author, however, retorts testily, " Oh, you know I did not mean that " : but he has written it ; and it is not fair for an author to think in the rough, to scribble unchastened whatsoever comes into his head, so that, as Erasmus said, "Apollo only could discern his meaning," and to throw the control and revision upon the vigUance of the reader. For instance : — ' It is our duty not to give hasty judgments till we have all the facts before us ' (and then may we ?). ' He abjured the errors of Protestantism to embrace those of Catholi- cism ' (is this sarcasm or muddle ?). ' This teaching if much longer denied threatens to be attended with disastrous results.' 'He complained of the information which was being kept from him.' ' In- temperance predisposed to, and prohaUy caused this disease.' ' A child who has been in a cretinous condition for years will not improve to such an extent as one who has been detected early ' (as if mere detection would do him good). In few theses, even of plain matter enough, have I not to prop up I INTEODUCTOEY 25 maimed or rickety conceptions, to dissect conven- tional phrases or equivocal words, and to sweep aside page after page of loose vesture which nowhere fits the thought closely, nor moves freely with it. A thinker who has grappled with his thoughts may write a burdened or too obscurely allusive style, especially if his subject matter be complex and recondite ; but never, anything so ungainly as this : Eschatology naturally interests a region essentially con- nected with a theory of the conflict of good and evil powers. In nature there is no great and small; the careful precision, even of a word, often so bites into the matter as to lead the author to revise or enlarge his thought ; slovenly writing is not only for the most part slovenly thinking, but slovenly habits of expression corrode thought in its very substance.
