ONE OF THE JUDGES OF THE COURT OF KING'S BENCH, THIS WORK IS INSCRIBED, AS A SMALL MEMORIAL OF ANCIENT FRIENDSHIP. ( vii ) PREFACE. THE reign of George III. may in some important re- spects be justly regarded as the Augustan age of modern history. The greatest statesmen, the most consummate captains, the most finished orators, the first historians, all flourished during this period. For excellence in these departments it was unsurpassed in former times, nor had it even any rivals, if we except the warriors of Louis XIV.'s day, one or two states- men, and Bolingbroke and Massillon as orators. But its glories were not confined to those great departments of human genius. Though it could show no poet like Dante, Milton, Tasso, or Dryden ; no dramatist like Shakspeare or Corneille ; no philosopher to equal Bacon, Newton, or Locke, — it nevertheless in some branches, and these not the least important of natural science, very far surpassed the achievements of former days, while of political science, the most important of all, it first laid the foundations, and then reared the superstructure. The science of chemistry almost entirely, of political economy entirely, were the growth viii PREFACE. of this remarkable era ; while even in the pure mathe- matics a progress was made which almost changed its aspect since the days of Leibnitz and Newton. The names of Black, Watt, Cavendish, Priestley, Lavoisier, Davy, may justly be placed far above the Boyles, the Stahls, the Hales, the Hookes of former times ; while Euler, Clairault, Lagrange, La Place, must be ranked as analysts close after Newton himself, and above Des- cartes, Leibnitz, or the Bernouillis ; and in economical science, Hume, Smith, and Quesnai really had no pa- rallel, hardly any forerunner. It would also be vain to deny great poetical and dramatic genius to Goldsmith, Voltaire, Alfieri, Monti, and the German school, how inferior soever to the older masters of song. But, above all, it must not be forgotten, that in our times the mighty revolution which has been effected in public affairs, and has placed the rights of the people throughout the civilized world upon a new and a firm foundation, was brought about, immediately in- deed by the efforts of statesmen, but prepared, and remotely caused, by the labours of philosophers and men of letters. The diffusion of knowledge among the community at large is the work of our own age, and it has made all the conquests of science both in recent and in older times of incalculably greater value, of in- comparably higher importance to the interests of man- kind, than they were while scientific study was con- fined within the narrow circles of the wealthy and the learned. PREFACE. ix Having, therefore, on retiring from office, more time left for literary pursuits than professional and judicial duties had before allowed me, I was not minded to waste, indolent and inactive, or enslaved by lower occupations, that excellent leisure : — " Non fuit consi- lium socordia atque desidia bonum otium conterere; neque vero agrum colendo, aut venando, servilibus offi- ciis intentum, setatem agere. Statutum res gestas po- puli nostri carptim, ut queeque memoria digna videban- tur, perscribere ; eo magis quod mihi a spe, metu, par- tibus reipublicse, animus liber erat."* For I conceived that as portrait-painting is true historical painting in one sense, so the lives of eminent men, freely written, are truly the history of their times ; and that no more authentic account of any age, its transactions, the springs which impelled men's conduct, and the merits which different actors in its scenes possessed, can be obtained than by studying the biography of the per- sonages who mainly guided affairs, and examining their characters, which by their influence they im- pressed upon the times they flourished in. Such a work had moreover this advantage, that beside pre- serving the memory of past events, and the likeness of men who had passed from the stage, it afforded fre- quent opportunities of inculcating the sound principles of an enlightened and virtuous policy, of illustrating their tendency to promote human happiness, of exhi- * Sail., Cat., cap. iv. x PREFACE. biting their power to raise the genuine glory as well of individuals as of nations. Though I could entertain no douht that this plan was expedient, no one could more doubt than I did the capacity brought to its execution, or feel more dis- trustful of the pen held by a hand which had so long been lifted up only in the contentions of the Senate and the Forum. My only confidence was in the spirit of fairness and of truth with which I entered on the performance of the task ; and I now acknowledge with respectful gratitude the favour which the work has hitherto, so far above its deserts, experienced from the public, both at home, in spite of party opposition, and abroad, where no such unworthy influence could have place. It is fit that I also express my equal satisfac- tion at the testimony which has been borne to its strict impartiality by those whose opinions, and the opinions of whose political associates, differed the most widely from my own. That in composing the work I never made any sacrifice of those principles which have ever guided my public conduct, is certain ; that I never concealed them in the course of the book is equally true ; nay, this has been made a charge against it, as if I was at liberty to write the history of my own times, nay, of transactions in many of which I had borne a forward part, and not show what my own sentiments had been on those very affairs. But if my opinions were not sacrificed to the fear that I might offend the living by speaking plainly of the PREFACE. xi dead, so neither were truth and justice ever sacrificed to those opinions. The Statesmen of George the Third's age having thus formed the subject of the volumes already pub-* lished, I now offer to the attention of the reader a more full and elaborate view of the Learned Men who flourished in the same period. In my opinion, these, the great teachers of the age, covered it with still greater glory than it drew from the Statesmen and the Warriors who ruled its affairs. It was neces- sary to enter much more into detail here than in the former branch of this work, because a mere general description of scientific or of literary merit is of ex- ceedingly little value, conveying no distinct or precise idea of the subject sought to be explained. It ap- peared the more necessary to discuss these matters minutely, because upon some of them much prejudice prevailed, and no attempt had hitherto been made to examine them completely, or even impartially. Of this a remarkable example is afforded by the want of any thing that deserves the name of a Life of Voltaire, and by the great prejudices, both favour- able and unfavourable to him, which, among differ- ent classes, exist on the subject. But it must also be observed that Dr. Black's discoveries have been far from attaining the reputation which they so well de- serve as the foundation of modern chemistry ; and justice to this illustrious philosopher required that the consequences arising from his modesty and his great xiv PREFACE. powers so infinitely below theirs, he may hope to have obtained some little success, and done some small service to the good cause, he can only ascribe this fortune to the intrinsic merits of that cause which he has ever supported.* He ventures thus to hope that no one will suspect him of being the less a friend to religion, merely because he has not permitted his sincere belief to make him blind regarding the literary merit of men whose opinions are opposed to his own. His censures of all indecorous, all unfair, all ribald or declamatory attacks, however set off by wit or graced by eloquence, he has never, on any occasion, been slow to pronounce.

VOLTAIRE. THIS name is so intimately connected in the minds of all men with infidelity, in the minds of most men with irreligion, and, in the minds of all who are not well- informed, with these qualities alone, that whoever undertakes to write his life and examine his claims to the vast reputation which all the hostile feelings excited by him against himself have never been able to destroy, or even materially to impair, has to labour under a great load of prejudice, and can hardly expect, by any detail of particulars, to obtain for his subject even common justice at the hands of the general reader. It becomes, therefore, necessary, in the outset, to remove a good deal of misunderstanding which, from the popular abuse of language, creates great con- fusion, in considering the history and weighing the merits of this extraordinary person. The mention of Voltaire at once presents to every one the idea, not so much of a philosopher whose early inquiries have led him to doubt upon the foundations of religion, or even to disbelieve its truths, as of a bitter enemy to all belief in the evidence of things B 2 VOLTAIRE. unseen — an enemy whose assaults were directed by malignant passions, aided by unscrupulous contrivances, and, above all, pressed by the unlawful weapon of ridicule, not the fair armoury of argument ; in a word, he is regarded as a scoffer, not a reasoner. Akin to this is the other charge which makes us shudder by the imputation of blasphemy. Now, upon this manner of viewing Voltaire some things are to be explained, and some to be recalled, that they may be borne in mind during the discussion of his character. Let us begin with the last charge, because, until it is removed, no attention is likely to be gained by any- thing that can be urged in defence or in extenuation. It is evident that, strictly speaking, blasphemy can only be committed by a person who believes in the existence and in the attributes of the Deity whom he impugns, either by ridicule or by reasoning. An atheist is wholly incapable of the crime. When he heaps epithets of abuse on the Creator, or turns His attributes into ridicule^ he is assailing or scoffing at an empty name — at a being whom he believes to have no existence. In like manner if a deist, one who dis- believes in our Saviour being either the Son of God or sent by God as his prophet upon earth, shall argue against his miracles, or ridicule his mission or his person, he commits no blasphemy; for he firmly believes that Christ was a man like himself, and that he derived no authority from the Deity. Both the atheist and the deist are free from all guilt of blas- phemy, that is, of all guilt towards the Deity or towards Christ. It is wholly another question whether or not they are guilty towards men. They VOLTAIRE. 3 plainly are so if they use topics calculated to wound the feelings of their neighbour who believes what they disbelieve ; because religion, unlike other subjects of controversy, is one that mixes itself with the strongest feelings of the heart, and these must not be rudely outraged ; because no man can be so perfectly certain that he is himself right and others are wrong, as to justify him in thus making their opinions the subject of insolent laughter or scurrilous abuse ; because it is our duty, even when fully convinced that we are dealing with error, and with dangerous error, to adopt such a course as will rather conciliate those we would gain over to the truth than make them shut their eyes to it by revolting their strongest feelings. Hence all law-givers have regarded such scoffing and insolent attacks on the religion professed by the great majority of their subjects as an offence justly punishable ; although it may fairly be doubted whether the inter- position of the law has ever had a tendency to protect religious belief itself, and may even be suspected of having favoured the designs of those who impugn it, both by the reaction which such proceedings always occasion, and by the more cautious and successful methods of attack to which they usually drive the oppo- nents of the national faith. But the offence, whether punished by the laws or not, is very incorrectly, though very generally, termed blasphemy, which is the offence of scoffing at the Deity, and assumes that the scoffer believes in him. Now it is barely possible that this offence may be committed ; but it is the act of a mad rather than a bad man. If, indeed, any one really believing pretends to unbelief in order to B2 4 VOLTAIRE. indulge in scoffing, no language is too strong to express the reprobation he deserves, if he be in his senses ; for he adds falsehood to a crime so horrible as almost to pass the bounds of belief — the frightful act of wilfully rebelling against the Almighty Creator of heaven and earth. — This is the first and worst form of the offence. Secondly : The like guilt will, to a certain extent, be incurred by him who vents his ribaldry, upon the mere ground of his scepticism. On such a subject doubting is not enough. Unless there is an entire conviction in the mind that the popular belief is utterly groundless in the one case (that of attacking the Deity) that there is a God, in the other (attacking1 Christianity) that there is a foundation for revelation, the guilt of blasphemy is incurred. He must be con- vinced, not merely doubt, or see reason for doubting ; because no one has a right to speculate and take the chances of being innocent ; guiltless if his doubts are well founded, guilty if they are not. The virtuous course here is the safe one. This is the moral of the fable in which the hermit answers the question of the rake, " Where are you, father, if there be not another world ?" with the other question, " And you, my son, if there be?'* We need not go so far as some have done, who on this ground contend that it is safer always to believe than to doubt, because belief must ever, to be of any value, depend on conviction. But we may assuredly hold that the better conduct is that which abstains from attack and offence where the reasons hang in suspense — abstains because of the great guilt incurred if the doubts should prove groundless. It is a third and lesser degree of this offence if a VOLTAIRE. 5 person carelessly gives way to a prevailing unbelief, and does not apply his faculties to the inquiry with that sober attention, that conscientious diligence, which its immense importance demands of all rational creatures. No man is accountable for the opinion he may form, the conclusion at which he may arrive, provided that he has taken due pains to inform his mind and fix his judgment. But for the conduct of his understanding he certainly is responsible. He does more than err if he negligently proceeds in the inquiry; he does more than err if he allows any motive to sway his mind save the constant and single desire of finding the truth ; he does more than err if he suffers the least influence of temper or of weak feeling to warp his judgment ; he does more than err if he listens rather to ridicule than reason, unless it be that ridicule which springs from the contemplation of gross and manifest absurdity, and which is in truth argument and not ribaldry. Now by these plain rules we must try Voltaire ; and it is impossible to deny that he possessed such sufficient information, and applied his mind with such sufficient anxiety to the discovery of truth, as gave him a right to say that he had formed his opinions, how erroneous soever they might be, after inquiring, and not lightly. The story which is related of the Master in the Jesuits' Seminary of Louis le Grand, where he was educated, having foretold that he would be the Corypheus of deists, if true, only proves that he had very early begun to think for himself; and whoever doubted the real presence, or questioned the power of absolution, was at once set down for an infidel ip 6 VOLTAIRE. those countries and in those times. It would be the fate of any young scholar in the Roman colleges at this day, especially were he to maintain his doubts with a show of cleverness ; and were he to mingle the least wit with his argument, he would straight- way be charged with blasphemy. But it must be added that an impression unfavourable to the truths of religion, and its uses, was made upon Voltaire's mind by the sight of its abuses, and by a consideration of the manifest errors inculcated in the Romish system. It is not enough to bring him within the blame above stated under the third head, that he was prejudiced in conduct- ing his inquiries, if that prejudice proceeded from the errors of others which he had unjustly been summoned to believe. He is not to be blamed for having begun to doubt of the truths of Christianity in consequence of his attention having originally been directed to the foundations of the system by a view of the falsehoods which had been built upon those truths. Even if the bigotry of priests, the persecutions of sovereigns, the absurdities of a false faith, the grovelling superstitions of its votaries, their sufferings, bodily as well as mental, under false guides and sordid pastors, roused his indignation and his pity, and these alternating emotions first excited the spirit of inquiry, afterwards too much guided its course, we are not on that account to con- demn him as severely as we should one who, from some personal spleen or individual interest, had suffered his judgment to be warped, and thus, as it were, lashed himself into disbelief of a system alto- gether pure, administered by a simple, a disinterested, a venerable hierarchy. VOLTAIKE. 7 Let us for a moment, independent of what may be termed the political view of the question — independent of all that regards the priesthood — consider the posi- tion of a person endowed with strong natural faculties, and not under the absolute dominion of his spiritual guides, nor prevented by their authority from exercising his reason ; but, on the contrary, living at a moment when a spirit of free inquiry was beginning generally to prevail. He is told that the mystery of transubstan- tiation must be believed by him as a fact; he is told that there has been transmitted through a succession of ages from the apostles one of the Divine attributes, the power of pardoning sin, arid that the laying a priest's hands on a layman gives him this miraculous power, to be exercised by him how guilty soever may be his own life, how absolutely null his own belief in the Divine being — nay, that this power has come through certain persons notorious atheists themselves, and whose lives were more scandalously profligate than anything that a modest tongue can describe. Presented to a vigorous mind, and not enforced by an authority which suffers no reasoning, or if enforced yet vainly so enforced, these dogmas and these claims became the subject of discussion, and were rejected almost as soon as they were understood. .But in company with them were found many other doctrines and pretensions of a very different complexion, yet all of them were pro- nounced to have the same Divine original ; and no greater sanctity, no higher authority, no deeper vene- ration was claimed for them than for the real presence of the Creator at the summons of the priest, or the 8 VOLTAIRE. participation of that priest in the attributes of the God- head. Let us be just towards the youth who was placed in these circumstances, and let us not condemn him for hastily rejecting the wheat with the chaff, before we endeavour to place ourselves in the same situation, asking what effect would be produced on our minds by severe denunciations against us should we doubt the priest's power, or refuse an explicit assent to his dogmas, which our reason, nay our senses rejected, while he refused all access to the inspired volumes which contained, or were said to contain, their only warrant. Rejecting the false doctrines, the chances are many that our faith would be shaken in the true. How many Protestants were made in the sixteenth century by the sale of indulgences ! But how many unbelievers in Christianity have been made in all ages of the Church by the grosser errors of Rome, the exorbitant usurpations of her bishops, and the preposterous claims of her clergy ! It is also to be observed that Voltaire was, through his whole life, a sincere believer in the existence and attributes of the Deity. He was a firm and decided, and an openly declared unbeliever in Christianity, but he was, without any hesitation or any intermission, a theist. Then in examining, the justice of the charge of blasphemy it is to be borne in mind that not one irreverent expression is to be found in all his number- less writings towards the Deity in whom he believed. He has more ably than most writers stated and illus- trated the arguments in favour of that belief. He has consecrated some of his noblest poetry to celebrate the VOLTAIRE. 9 powers of the Godhead.* Whatever exceptionto this assertion may seem to be found in those writings will, on consideration, prove to be only apparent. It will be found that he is speaking only of the Deity as represented in systems of religion which he dis- believed \ consequently he is there ridiculing only the idols, the work of men's hands, and the objects of superstitious worsftip, not the great Being in whom he believed and whom he adored. Even his ' Candide,' one of his greatest, perhaps his most perfect work, is only intended to expose the extravagance of the optimist doctrine ; and however we may lament its tone in some sort, it is certainly not chargeable with ridiculing any- thing which a philosophic theist must necessarily believe. But no one can exempt Voltaire from blame for the manner in which he attacked religious opinions, and outraged the feelings of believers. There he is without defence. Had all men been prepared to make the step * His dramatic compositions abound in such religious sentiments, clothed in the noblest language of poetical abstraction ; but his celebrated verses, said to have been written extempore in a com- pany that were admiring the firmament one summer's evening, may be placed by the side of the finest compositions in that kind — " Tous ces vastes pays d'azur et de lumiere, Tires du sein du vide, formes sans matiere, Guides sans compas, tournans sans pivot, N'ont a peine coute la depense d'un mot." When I once cited these to my illustrious friend Monti, who never would allow any poetical merit to the French, he objected to the last phrase, which he called the pivot, as low and prosaic, and as affording a proof of his constant position that the French have no poetical language. 10 VOLTAIRE. which he had himself taken, the wound would have been inconsiderable. But he must have written with the absolute certainty that their religious belief would long survive his assaults, and that consequently, to the vast majority of readers, tbey could only give pain. Indeed he must, in the moments of calm reflection, have been aware that reasoning, and not ridicule, is the proper remedy for religious error, and that no one can heartily embrace the infidel side of the great question merely because he has been made to join in a laugh at the expense of absurdities mixed up with the doctrines of believers ; nay, even if he has been drawn into a laugh at the expense of some portion of those doctrines themselves It is no vindication for Voltaire against this heavy charge, but it may afford some palliation of his offence, if we reflect on the very great difference between the ecclesiastical regimen under which he lived, and that with which we are acquainted in our Protestant community. Let no man severely condemn the untiring zeal of Voltaire, and the various forms of attack which he employed without measure, against the religious institutions of his country, who is not prepared to say that he could have kept entire possession of his own temper, and never cast an eye of suspicion upon the substance of a religion thus abused, nor ever have employed against its perversions the weapons of declamation and of mockery ; had he lived under the system which regarded Alexander Borgia as one of its spiritual guides, which bred up and maintained in all the riot of criminal excess an aristocracy having for one branch of its resources the spoils of the altar, which practised persecution as a favourite means of conviction, VOLTAIRE. 11 and cast into the flames a lad of eighteen, charged with laughing as its priests passed by. Such dreadful abuses were present to Voltaire's mind when he attacked the Romish superstitions, and exposed the profligacy, as well as the intolerance, of clerical usurpation. He unhappily suffered them to poison his mind upon the whole of that religion of which these were the abuse ; and, when his zeal waxed hot against the whole system, it blinded him to the unfairness of the weapons with which he attacked both its evidences and its teachers. The doctrine upon toleration, upon prosecutions for infidelity, even for blasphemy, which I have now ven- tured to propound,. is supported by the very highest authority among persons of the most acknowledged piety, and of the warmest zeal for the interests of re- ligion. It was the constant maxim of my revered friend, Mr. Wilberforce, that no man should be prosecuted for his attacks upon religion. He gave this opinion in Parliament ; and he was wont to say, that the ground of it was his belief in the truths of religion. "If religion be, as I believe it, true, it has nothing to fear from any such assaults. It may be injured by the secular arm interfering." Just so the well-known Duke of Queensberry, when conversing upon the writings of Paine, and other assailants of the consti- tution, made answer to a sycophant, who said of those attacks, "And so false too," — " No," said his Grace, "not at all : they are true, and that is their danger, and the reason I desire to see them put down by the law ; were they false, I should not mind them at all." In the like spirit we have the unsuspected testimony of men like Dr. Lardner and Bishop Jeremy Taylor, 12 VOLTAIRE. Christians whose piety and virtue, and whose orthodoxy, are beyond all suspicion : — "The proper punishment," says Lardner, "of a low, mean, indecent, scurrilous way of writing, seems to be neglect, contempt, scorn, and final indignation" (Letter to the Bishop of Chester on the Prosecution of Woohton, 1729). — "Blasphemy" (says Taylor) " is in aliena republica, a matter of another world. You may as well cure the colic by brushing a man's clothes, or fill a man's belly with a syllogism, as prosecute for blasphemy. Some men have believed it the more as being provoked into a confidence and vexed into a resolution. Force in matters of opinion can do no good, but is very apt to do hurt ; for no man can change his opinion when he will. But if a man cannot change his opinion when he list, nor ever does heartily or resolutely but when he cannot do other- wise, then to use force may make him a hypocrite, but never to be a right believer ; and so, instead of erecting a trophy to God and true religion, we build a monument for the devil" (Liberty of Prophesying, s. xiii. 19.) — Bishop Warburton says plainly, "he should have been ashamed of even projecting to write in defence of Moses had he not thought that all infidels had equal liberty to attack him." (Dedication to the Divine Legation.) These things being premised, we may now proceed with more ease and less interruption from controversial topics, to examine the extraordinary history of this eminent person. He was the son of the Sieur Arouet, a person of respectable family, filling the place of treasurer in the Chamber of Accounts, an exchequer office of con- VOLTAIRE. 13 siderable emolument. His mother was of a noble family, that of d'Aumart. A small estate possessed by the father was called Voltaire ; and the custom in those days being for the younger children of wealthy commoners to take the name of their estate, leaving the family name to the eldest, Francois Marie, as the younger of two sons^ took the name of Voltaire, which on his brother's death many years after he did not change. He was born the 20th of February, 1 694 ; and being so feeble that his life was not expected, he was baptised immediately, the christening being deferred till the 22d of November following. This has given rise to doubts at which of the two periods his birth took place. It has frequently been remarked as a singular circumstance, that two eminent authors who have lived to extreme old age, Fontenelle and Voltaire, were both thus unlikely at their birth to live at all, both being born almost in a dying condition ; yet not only did they enjoy unusually long life, but they retained their great faculties entire to the last, although the one died in his eighty-fifth year, and the other lived to within a few weeks of a hundred. When only twelve years of age, he distinguished himself by the excellence of some begging verses to the Dauphin from an invalid who had served under the prince, and who applied for this help to the Master of the College of Louis le Grand, where Vol- taire then was. The master being busy, handed him over to his promising scholar, as being quite able to do what was desired. The lines are very good, and the idea sufficiently happy. The old soldier is made to say that the different heathen gods having given 14 VOLTAIRE. Monseigneur various gilts at his birth, a more benefi- cent Deity had provided the petitioner's Christmas- box by bestowing on their favourite the boon of ge- nerosity. It is known that this incident procured for him the favour of the famous Ninon de 1'Enclos, then in her ninetieth year, and to whom he was presented by his godfather, the Abbe de Chateauneuf. She died soon after, and left him a legacy of 2,000 francs, to buy books with.* When his father found that he was introduced by the Abbe into this and other fashion- able society, and that he was cultivating his taste for poetry, he became alarmed for his success in life, having destined him for the profession of the law. He placed him, therefore, in a school of jurisprudence, intending to purchase for him a President's place, ac- cording to the practice of the French bar in those days. Voltaire, however, had already begun to taste the sweets * He has, in a letter which remains (Melanges Lit., ii. 294), recorded many particulars of her extraordinary life and great qualities. Her portrait by St. Evremond is well known ; it is happily drawn : — " L'indulgente et sage Nature A forme 1'ame de Ninon De la volupte d'Epicure, Et de la vertu de Caton." In consequence of a quarrel between two of her lovers there was a proposition of sending her to a convent of " Filles repenties :" she said that would not suit her, as she was " ni fille, ni repentie" The provident parents in good society used to place their sons under her patronage to form them for polite company. Of one Renaud, a coxcomb whom she was said to have formed, she observed, " Qu'elle faisait comme Dieu, qui s'e*tait repenti d'avoir fait Thornine." When her old and intimate friend, Madame de Maintenon, be- came devote, and offered to provide handsomely for her would she but follow her example, her answer was, " Je n'ai nul besoin ni de fortune, ni de masque." VOLTAIRE. 15 of* classical study, and he had lived in a society fre- quented by the Abbe his godfather, who appears to have been a person of loose morals and of sceptical opinions. The extreme bigotry which Madame de Maintenon had introduced into the Court of Versailles when the declining faculties and health of Louis XIV. had rendered him the victim of superstitious terrors, and, through these, the tool of priestly intole- rance, gave rise to a reaction in the gay circles of Paris ; and in resisting the inroads of that gloom by which the asceticism of the ancient mistress had signa- lised her late repentance, the Contis, the Chaulieus, the Sullys, the La Feres, carried their opposition further than they perhaps at first intended, or even afterwards were aware of : they patronised universal discussion, even of the most sacred subjects, and best received opinions, until a fashion of free thinking was set ; and from being at first revolted at the intolerance which destroyed Catinat at Court, notwithstanding his genius and his probity, on account of his supposed infidelity, and ascribed the defeats of Vendome to his occasional absence from mass, without reflecting that Marlborough was a heretic and Eugene a deist ; the frequenters of the most polished society in the world became accustomed to believe more sparingly than Catinat, and see less of the Host than Vendome. It was in this association that Voltaire, then a boy, became inured to the oblivion both of his law books and of his religious principles, when his parent made a last effort to save him, and restore him to the learned profession, and to the bosom of the church, by sending him as page or attache to the French am- 16 VOLTAIRE. bassador at the Hague, a near kinsman ^of the Abbe Chateauneuf. He there fell in love with the daughter of a profligate woman, Madame Dunoyer, who considering the match a bad one, had him sent home by the ambassador, and published his love let- ters, which are admitted to have no merit. His father would only receive him on condition of his consenting to serve in a notary's office. A friend of the family, M. de Caumartin, had compassion on the sufferings which this arrangement occasioned, and obtained per- mission to have him pass some months in his country residence at St. Ange. The Bishop Caumartin, then an elderly man, and who had lived with all the more learned persons of the past age, excited him, by his conversation upon the Sullys and the Henrys, to meditate two of the greatest of his works, his epic poem and his history. The death of Louis, which happened on Voltaire's return to Paris, gave rise to a very indecent expression of public joy, and to many libels upon his memory. One of these being without any foundation ascribed to him, his confinement in the Bastille was the conse- quence. Here, however, his spirit continued unbroken. He sketched the poem of the 'League,' afterwards called the 'Henriade ;' and he corrected a tragedy, ' CEdipe,' which he had written several years before, when only eighteen years old. The imprisonment being in the course of a few weeks found to be entirely illegal and vexatious, the Regent ordered his immediate liberation, with a sum of money by way of compensation. The tragedy was not acted till two years after, in 1718 ; and it is a singular fact, that when, in 1713, it had VOLTAIRE. 1 7 been in its original imperfect state submitted to Dacier, with the pedantry of his nature he strongly recom- mended the introduction of choruses, to be sung after the manner of the Greek tragedy. A letter of his is still extant, giving this sage and practical counsel ; but the Greek critic was not the only pedant. When in 1769, Voltaire had gained the famous cause of Sirven, through the exertions of M. Merville, a leading advocate of Toulouse, he refused all pecuniary remu- neration, but desired as his reward, that his client would now consent to add choruses to the ' GEdipe.' How powerful was the sentiment of ambition in his nature appears not merely from his bold attempt at a tragedy — audaxque juventa — in his eighteenth year, but from his adventurous competition for the prize of poetry proposed by the Academic Franchise a year or two before ; the king having, in the superstition of his declining age, at length resolved to fulfil the promise of his predecessor by decorating the altar of Notre Dame. This formed the subject of the ode, which was rejected in favour of a ridiculous piece by the Abbe Dujarri ; so that it is a singular fact in Voltaire's history that his first published work was a devotional poem. The tragedy of ' GEdipe' was successful ; and Lamotte, then of established reputation, but which with ordi- nary poets is by no means a security against jealousy, had the noble candour to declare that this tragedy gave sure promise of a successor to Corneille and Ra- cine. But the prejudices of the stage forced Voltaire to introduce a love scene against his better judgment, which had decided against the incongruous mixture of c 18 V.OLTAIBE. tenderness with the horrors of the subject. It is cJ related of him, and he has himself countenanced the anecdote, that in the giddiness of youth, and plunged in dissipation, he was insensible to the dangers of failure, and felt so little of the nervous agitation belonging to a dramatic author's first night, as to be seen carrying in mockery the train of the High Priest. Madame la Marechale de Villars, then at the head of Parisian society, asked who that young man was, who appeared as if trying to have the play damned ; and upon being told that it was neither more nor less than the author himself, she was so struck with the originality, that she desired to have him presented to her. Becoming one of her circle, he conceived for her the first and probably the only passion which he ever seriously felt. His love was unsuccessful ; but it interrupted his studies, nor did he ever after allude to it but with a feeling of regret bordering upon remorse. The merits of 'CEdipe' no longer form a debateable question. If the continued representation for forty- five nights had left any doubt upon this subject, the concurrent voices of so many different audiences during the sixty years and upwards that it has kept possession of the stage pronounce a sentence from which there is no appeal.* For an author of any age it is a fine * The judgments pronounced by the audience on a first represent- ation are a very different test, being necessarily much more subject to accident, to caprice, and to party manoevures. The striking example of the ' Britannicus,' nay, even of the ' Phedre' and the ' Athalie ' themselves (these two now admitted on all hands to be Racine's masterpieces), may well guard us against yielding to the VOLTAIRE. 19 performance; for a young man of eighteen or nine- teen, a truly wonderful one ; promising, perhaps, considerably greater dramatic success than even the author of ' Zaire' ever attained. But he unfortunately preferred writing mult a than multum ; and this remark is more peculiarly applicable to his dramatic compo- sitions than to any of his other important efforts. The distinguishing beauty of the ' CEdipe* is its fervid, correct, and powerful declamation ; and though the most magnificent passage be taken from Sophocles, there are numberless others of undoubted originality. Into some of the inconsistencies, and even absurdities, of the Greek plot he has fallen, and the most of whatever is good in that plot certainly is not his own. But no one who has either seen the representation or read the poem, can easily forget the powerful im- pression which its diction leaves on the mind. Some of the passages are marked by their supposed allusion to the priesthood of his own times ; and one especially is generally given as his first declaration of war against the sacred order : — " Nos pretres ne sont point ce qu'un vain peuple pense — Notre credulite fait toute leur science." — (Act iv. sc. 4.) But surely, when we observe that this is only the first expressions of the vox populi. Perhaps even the great union of opinion in France, placing Corneille so far above Racine, is another instance of erroneous judgment produced by accidental circum- stances. Had Racine preceded Corneille, would the decision have been the same ? There may, however, be some ground for giving the same precedence to the latter that we yield to Massillon and Bourdaloue over Bossuet. c 2 20 VOLTAIRE. summing up of an invective satirical, but perfectly just, against the Pagan superstitions which are spe- cified, we may well suppose, that had not his future writings supplied the commentary, no one could have deemed the allusion in these fine lines irreverent to the hierarchy of Rome. Now, it is true, they are sufficiently marked ; and in consequence of that com- mentary they never fail to be applied. I recollect the thunder of applause which they called forth in 1814, when I saw this play during the first restor- ation. The court of Louis XVIII. was supposed to favour the Church in an especial manner, and this pointed the public attention more peculiarly to such allusions. Two other lines were productive of nearly equal applause : — " Tin pr£tre,"quel qu'il soit, quelque Dieu qui 1'inspire, Doit prier pour ses rois, et non pas les maudire." (Act iii. sc. 3.) The reason of this excitement was, that the lines contain a reproof of the High Priest's insolence, and that was sufficient. On another occasion, the same season, I heard much louder applause in that theatre. It was of the lines, " Le premier qui fut roi, fut un soldat heureux : Qui sert bien son pays n'a pas besoin d'a'ieux." The reference was instantly made to Napoleon, and the piece could hardly proceed for the boisterous plaudits. It is certain that the tragedies of Voltaire are the works of an extraordinary genius, and that only a great poet could have produced them ; but it is equally certain that they are deficient for the most VOLTAIRE. 21 part in that which makes the drama powerful over the feelings, — real pathos, real passion, whether of tenderness, of terror, or of horror. The plots of some are admirably contrived ; the diction of all is pure and animated ; in most passages it is pointed, and in many it is striking, grand, impressive ; the cha- racters are frequently well imagined and portrayed, though without sufficient discrimination; and thus often running one into another, from the uniformity of the language, terse, epigrammatic, powerful, which all alike speak. Nor are there wanting situations of great effect, and single passages of thrilling force ; but, after all, the heart is not there ; the deep feeling, which is the parent of all true eloquence as well as all true poetry, didactic and satirical excepted, is rarely perceived ; it is rather rhetoric than eloquence, or, at least, rather eloquence than poetry. It is de- clamation of a high order in rhyme ; no blank verse, indeed, can be borne on the French stage, or even in the French tongue ; it is not fine dramatic composition : the periods roll from the mouth, they do not spring from the breast ; there is more light than heat ; the head rather than the heart is at work. It seems that if there be any exception to this remark, we must look for it in the ' Zaire,' his most perfect piece, although, marvellous to tell, it was written in two and twenty days. In my humble opinion, it is certainly obnoxious to the same general objection, though less than any of his other pieces; yet it is truly a noble performance, and it unites many of the great requisites of dramatic excellence. The plot, which he tells us was the work of a single day, 22 VOLTAIRE. is one of the most admirable ever contrived for the stage, and it is a pure creation of fancy. Nothing can be conceived more full of interest and life and spirit — nothing more striking than the combinations and the positions to which it gives rise, while at the same time it is quite natural, quite easy to conceive, in no particular violating probability. Nor can any- thing be more happy or more judicious than the manner in which we are, at the very first, brought into the middle of the story, and yet soon find it unravelled and presented before our eyes without long and loaded narrative retrospects. Then the characters are truly drawn with a master's hand, and sustained perfectly and throughout both in word and in deed. Orosman, uniting the humanized feelings of an amiable European with the unavoidable remains of the Oriental nature, ambitious, and breathing war, more than becomes our character, yet generous and simple-minded ; to men imperious, but as it were by starts, when the Tartar predominates ; to women deli- cate and tender, as if the Goth or the Celt prevailed in the harem ; unable to eradicate the jealousy of the East, yet, like a European, too proud not to be ashamed of it as a degradation, and thus subduing it in all instances but one, when he is hurried away by the Asiatic temperament and strikes the fatal blow, which cannot lessen our admiration, nor even wholly destroy our esteem. The generous nature of Nour- estan and Lusignan excites our regard, and, perhaps, alone of all the perfect characters in epic or in dramatic poetry, they are no way tiresome or flat. But Zaire herself, unlike other heroines, is, if not the first, at VOLTAIRE. 23 least equal to the first, of the personages in touching the reader and engaging his affections. Nothing can be conceived more tender; and the conflict between her passion for the Sultan and her affection for her family, between her acquired duty to the crescent and her hereditary inclination to the cross, is most beau- tifully managed. Of detailed passages it would be endless to make an enumeration, but some may be shortly marked. Few things in poetry are finer than Lusignan's simple answer to Chatillon, who tells him that he was impotent to save his children : " C. Mon bras charge de fers ne les put pas secourir. L. Helas! et j'etais pere, et je ne pus mourir." Nourestan's indignation, the boiling over of a fana- tical crusader's enthusiasm against his sister for falling in love with an infidel prince (Act iii. sc. 4), is a truly noble piece of declamation. Orosman's proud feeling towards the sex, for the first time following the Asiatic course (Act iii. sc. 7), is not less finely expressed: " Mais il est trop honteux de craindre une maitresse — • Aux moeurs de 1'Occident laissons cette bassesse ! Ce sexe dangereux, qui veut tout asservir, S'il regne dans 1'Europe, ici doit obe'ir." The famous passage " Zaire, vous pleurez ?" which electrified the audience in France, and never fails still to produce this effect, needs not be specified, ex- cept for the purpose of noting, that the exclamation " Zaire, vous m'aimez !" is hardly less touching, or less powerful to paint the Sultan's character. Next to ' Zaire ' the ' Merope ' certainly is Voltaire's finest drama ; and its success at first was even greater than that of ' Zaire.' At one part the audience were so intoxicated with admiration, that they called out for 24 VOLTAIRE. Voltaire, and forced him to show himself — the first time that the honour was ever bestowed, which has now become worthless, because lavished on the author of every successful piece. But the multitude went a step further in his case, and insisted upon the beautiful daughter-in-law of the Marechale de Villars publicly saluting him ; a requisition savouring much more of indecorum than enthusiasm. It is impossible to deny either the great merits of the ' Merope/ or to doubt its marked inferiority to ' Zaire.' The composition, and, in general, the execu- tion, must be confessed to be in the best manner of that eloquence, or rather rhetoric, which I have ventured to describe as the character of Voltaire's tragedies ; but it is not, like ' Zaire,' at least many portions of ' Zaire,' a successful incursion into the adjoining, though far loftier domain of feeling : in a word, the high region of fine verse is here under the author's power ; the higher region of poetry does not submit to his con- trol. The fable is excellently pursued ; while there is little original or very happy in the characters, of which the principal one is so possessed by a feeling of love and anxiety for a son whom she had barely seen, that it is difficult to sympathise with the leading sentiment of the piece. Fine passages no doubt abound, and bursts (mouvemens) of an impressive, and of a sur- prising and even elevating kind, are occasionally intro- duced, though by far the finest is imitated professedly from the ' Merope ' of Maffei — it is when Egisthe men- tions his mother ; and Merope then believing that he had murdered her son, that is himself, exclaims — " Barbare ! il te reste une mere ! Je serois m£re encore sans toi," &c. — (Act iii. sc. 4.) VOLTAIRE. 25 The verses on a military usurper have been already cited. Lines such as the concluding couplet of the second act are not rarely scattered through the piece, and never fail to produce a great effect in the delivery. They have, like the former, been not rarely applied to Napoleon. " Quand on a tout perdu, quand on n'a plus d'espoir, La vie est un opprobre, et la mort un devoir." These, the ' Zaire' and ' Merope,' seem, beyond all com- parison, and without any doubt, to be the finest of Voltaire's dramatic works. His own favourite, how- ever, appears to have been the ' Catiline,' or ' Rome Sauvee.' He dwells with great complacency on its having been more applauded than * Zaire ' on its first representation, and accounts for its not having, like ' Zaire,' kept possession of the stage, by observing that nobody now-a-days conspires, but every one has loved. The superiority of this to its rival, the ' Catiline ' of Crebillon, is also admitted ; nor can we deny it a con- siderable degree of that which constituted Voltaire's dramatic merit, his eloquence far more remarkable than his poetry. It may also be admitted that if this criticism can ever lose its force, it must be in a com- position of which the hero is Cicero; — nor, if the eloquence were of a higher order, — if it were fervid and impassioned, — if it were warm from the heart, and addressed and moved the feelings, — would the de- cision of which the author appears to complain ever have gone forth against it. But the tragedy has, be- side many other faults, that of frigid declamation, in pure diction, often happy, generally pointed, even to epigram, but still cold and artificial. There is also to 26 VOLTAIRE. be remarked in the piece a singular want of judgment. The history of Catiline is not professed to be followed, yet all the departures from it are in diminution of the dramatic interest ; and nothing can be less correct than the assertion which accompanies the confession that the facts of the story are changed — it is not true, or anything like the truth, that the " genius and the character of Cicero, Catiline, Cato, and Csesar, are faithfully painted." Can anything be less excusable, whether we regard dramatic interest or the truth of history, than representing Catiline as uxorious, and all but won over to abandon his enterprise by his wife's remonstrances and tears ? The absurdity of making Csesar put down the conspiracy, and supersede C. Antonius and Petreius in the command at the battle in which Catiline fell, requires no comment. This, and Caesar's rhodomontade before setting out, his embracing Cicero, and vowing that he goes either to die, or to justify the Consul's good opinion of him, and his being overpersuaded by a speech of Cicero, not merely to abandon Catiline but to destroy him, is as utterly unlike that great man's character as anything that can well be imagined. For Cato, it is surely as little in his manner as can be, to tell Cicero that Rome calls him her father and her avenger ; and that Envy at his feet trembles and adores him : " Et TEnvie a tes pieds 1'admire avec terreur." But the grand defect of this piece is the absurd and hopeless attempt of bringing Cicero upon the stage. Brutus and Antony had been successfully so dealt with by Shakspeare ; but they were men of action ; VOLTAIRE. 27 Cicero, a mere orator, never could be endured as the hero of a piece ; eloquence, the triumphs of the tongue, are wholly unfitted to form the subject of a drama. Voltaire has endeavoured to supply the defect by mak- ing Catiline murder not his step-son, which he was supposed to have done, but his father-in-law, a certain Nonnius, which no one ever dreamt of but the poet ; and his wife, in her grief and rage, puts herself to death by stabbing herself on the stage. But if we desire to perceive how great is Voltaire's failure, we must not only consider what he has done to make his drama cold and uninteresting, but what ma- terials he had within his reach, and avoided using. Few narratives present so lively, nay, so dramatic a picture as that of Sallust. The diction is fine ; but had Livy written it, his exquisite and dignified style would have placed the Catiline conspiracy at the head of historical works. The character of Catiline, better given in some parts of Cicero, particularly the Pro Sulla, Pro Coelio, and Pro Mursena ; his dark, designing, and unscrupulous nature ; his utter profli- gacy of life and manners ; his fierce temper ; his un- tameable ambition ; his powers, as well of body as of mind; his invincible courage — all form a personage made for stage effect, and only prevented from pro- ducing it in the highest degree by such preposterous conceits as making him tender-hearted to his wife, a thing to have been carefully avoided by the dra- matist, even if his letter, given by Sallust, shows some care for that very profligate woman and his child. But then what can be finer than the meeting holden in a remote recess of his house, and his address under 28 VOLTAIRE. cloud of night to his associates — to say nothing of the dark suspicion thrown out by the historian, that he made them drink human blood mixed with their wine when he swore them to the enterprise !* But the speech is very fine — bold, abrupt, simple, concise, emi- nently calculated for the occasion : — " Quin igitur, expergiscemini ? En ilia, ilia quam ssepe optastis libertas ! Fortuna omnia victoribus prsemia posuit: res, tempus, pericula, egestas, belli spolia magnifica, magis quam oratio mea vos hortentur. Vel imperatore, vel milite me utimine. Neque animus, neque corpus a vobis aberit." The other speech which he makes on the eve of the fight is also very noble and charac- teristic : — " Quod si virtuti vestree fortuna inviderit, cavete inulte animam amittatis ; neu capti potius sicuti pecoratrucidemini, quam virorum more pugnantes,cruen- tam atque luctuosam victoriam hostibus relinquatis."f With such noble materials, Voltaire makes as poor a speech as it was possible to manufacture — as wordy and unimpressive. He calls his conspirators "an assemblage of the greatest of human kind ;" and that being not enough, they are " conquerors of kings — avengers of their countrymen — his true friends, his equals, his supports." He tells them that " they had subdued Tigranes and Mithridates, and made the Euphrates red with their blood, only to make worth- less senators proud, who, as a recompence, allowed the conspirators to adore their persons at a distance." How much finer is the simple description in Sallust ! — " The Patricians squander away their wealth in * Fuere ea tempestate qui dicerent. — (Cap. xxii.) f Cap. Iviii. VOLTAIRE. 29 building out the sea, and levelling mountains, while we are without the necessaries of life !" But the whole comparison is to the same effect. Then, can anything be finer than the scene in the Senate where Cicero made his first famous speech? First the historian paints Catiline as full of dissimulation, and acting the part of a suppliant, with downcast look and submissive voice, appealing to the senators whe- ther it wras likely a man of his rank and former services should be guilty of the things laid to his charge, while the state was defended by " M. Tullius Cicero, inqui- linus civis urbis Romee " (one living in a hired lodging). Thereupon a loud cry was raised against him, and he was saluted with the name of rebel and parricide. "Turn ille furibundus — ' Quoniam quidem circum- ventus, inquit, ab inimicis, prseceps agor, incendium meum ruina extinguam.' "* Thus the Catiline of Sallust; but he of Voltaire, after saying his part is taken, and calling his followers to come away, departs quietly enough — not the furi- bundus proripuit of Sallust, or even the triumphans gaudio erupit of Tully — but " Vous, senat, incertain, qui venez de m'entendre, Choisissez a loisir le parti qu'il faut prendre." And so it is throughout ; the same contrast between the tame, feeble, vague verses of the modern poet, and * Cap. xxxi. Cicero (pro Mursena, c. xxv.) gives a different account, but less picturesque : " erupit senatu triumphans gaudio ;" and adds, that he had some days before used the famous words in answer to a threat of prosecution from Cato ; but Voltaire was at perfect liberty to choose either version of the fact, and he preferred his own mean and most tame design. 30 VOLTAIRE. the spirited, the picturesque of the ancient historian, really a finer poet than he who would needs drama- tise the story into prose. The battle so exquisitely painted by Sallust could not indeed be rendered on the stage, but something of the noble speech that preceded might have been given. Then how tamely does Csesar, in recounting the fight, render the " Memor generis atque pristinse dignitatis, in confertissirnos hostes incurrit," and the sad and striking scene dis- played after the battle, when " quisque quern pugnando locum ceperat eum amissa anima corpore tegebat;" but Catiline, on the contrary, was found " longe a suis inter hostium cadavera, paululum etiam spirans, fero- ciamque animi quam habuerat vivus in voltu reti- nens."* This is far from the greatest failure of Voltaire, but it is a failure, and a failure by de- parting from the admirable simplicity of the original. " Catiline terrible au milieu du carnage, Entoure d'ennemis immoles a sa rage, Sanglant, couvert de traits, et combattant toujours, Dans nos rangs eclaires a termine ses jours. Sur des morts entasses I'effroi de Rome expire : Romain, je le condamne ; et soldat, je 1'admire." It may here be observed that the admirable trait of each soldier falling where he fought, but the terrible chief far apart from all his men, because in advance of them all, being first left out, the extraordinary effect of paululum etiam spirans where he had fallen, and the ferociam animi voltu retinens, are equally abandoned. * One never can read this great masterpiece of narrative without recollecting Quinctilian's phrase, " Salustii immortalem velocitatem." VOLTAIRE. 31 One is really tempted to question (as some have ques- tioned) Voltaire's thorough acquaintance with the force of the Latin tongue. Assuredly he very differently judges the eloquence of Massillon, in a language of which, like him, he was so accomplished a master. It would be unjust to close the ' Rome Sauvee' with- out awarding just praise to many of its detached parts, and especially of the lines, worthy of Cicero himself, which he is made to pronounce — " Remains, j'aime la gloire, et ne veux point m'en taire ! Des travaux des humains, c'est le digne salaire : Senat ! en vous servant, il la faut acheter ; Qui n'ose la vouloir, n'ose la meriter !" All accounts agree that when Voltaire, at the first representation of the piece in a private theatre, acted this part, his enthusiastic delivery of these words con- veying a sentiment so intimately mixed with his whole soul produced such an effect that the audience could hardly tell if it was the poet or the great orator they heard. The conspiracy of Catiline has afforded not only to Crebillon but to our Ben Jonson the subject of a tragedy. He copies, by translating, Sallust and Cicero ; but he does not preserve the fire of the one, or the picturesque effect of the other. The speech to the conspirators is but poorly rendered. Thus the Quin expergiscemini ? by being made an exhortation instead of a reproach, sinks into " Wake, wake, brave friends, And meet the liberty you oft have wished for." How much finer the literal version, " Why wake ye 32 VOLTAIRE. not ? See ! see ! that liberty you so often have wished for." Nothing can be more poor than the version in blank verse of the first Catilinarian, unless perhaps it be Catiline's exclamation on rushing forth from the Senate — " I will not burn without my funeral pile : It shall be in the common fire rather than mine own, For fall I will with all, ere fall alone." Nor is the speech before the battle better rendered ; thus — " And if our destiny envy our virtue The honour of the day, yet let us vow To sell ourselves at such a price as may Undo the world to buy us, and make Fate, While she tempts ours, fear her own estate." A piece of rant and fustian which the poet probably thought Sallust had not the genius to think of. The description of Catiline's body after the battle is not perhaps quite so bad, nor the idea lent to the historian so feeble — " Yet did his look retain Some of its fierceness, and his hands still moved, As if he laboured yet to grasp the state With these rebellious parts." Altogether the piece is incomparably inferior to Voltaire's in every part on which a comparison can be made. In learning, it is true, the Frenchman is far surpassed, who might have written his ' Catiline ' without ever having read a line either of the orator or of the historian ; but the Englishman's far greater failure is not excused by his attempt being the more learned. VOLTAIRE. 33 Of the inferior dramas, ' Alzire ' and ' Mahomet ' or ' Le Fanatisme ' are certainly the best ; but they are far from being equal to the ' Zaire ' and ' Merope,' though far superior to the ' Catiline.' The object of both is to present fanaticism in its most dangerous shape — in the union which it not unfrequently forms with great and even with good qualities. This object is well attained, and there is also a mixture of softness in the characters of Alzire and Palmire which forms a pleas- ing relief to the harsher features of Mahomet, Gusman, and Zamore. Both tragedies contain fine passages of declamation ; and the picture of the revolting and hateful character of the Spaniards (in the New World, at least) — that execrable and yet despicable mixture of cruelty and fanaticism, fraud and avarice — with which ' Alzire ' opens, is not surpassed in moral descriptive poetry. * Alzire ' was perfectly successful from the first ; but the favour which it then enjoyed has worn out. ' Mahomet ' was at first only performed at Lile, and during its first representation the news of Frede- rick's victory at Molwitz having been received by Vol- taire, he interrupted the performance to make it known, saying to those around him, " You'll see, that piece of Molwitz will make mine pass." At Paris it was for- bidden by the timidity of Cardinal Fleury, alarmed by some passages. Voltaire presented it to the Pope Benedict XIV. (Lambertini), accompanying it with two very indifferent Latin verses as an inscription for his Holiness's portrait. He received an answer full of kindness and liberality from that eminent priest, who also mentioned that an ignorant Frenchman had objected to the quantity of Hie in the Latin lines, D 34 VOLTAIRE. and that he had put him down with two lines of Virgil, showing it to be either long or short, though he had not read Virgil for fifty years. Voltaire replied that a third verse should have been given, and inscribed on the Pope's picture by all his subjects — " Hie vir, hie est tibi quern promitti saepius audis ;" adding very inaccurately, if not ignorantly, that the word is both long and short in this line, whereas it is only long by position. The late Lord Grantley told me that when he was a young man fresh from Eton, he passed a few days at Ferney, and found Voltaire much puzzled to restore, consistently with the metre, a Latin couplet which a stranger had made upon him, of which a word or two had been displaced. The Etonian pleased him exceed- ingly by at once performing the easy operation — " Ecce domus qualem Augusti non protulit setas Hie sunt Maecenas, Virgiliusque simul." The author of ' Catiline ' had confounded himself by beginning with domus. It must be added, however, that he wrote an excellent motto for a dissertation upon heat, which he preferred in the competition for an academy prize — " Ignis ubique lafcet, naturam amplectitur omnem Cuncta parit, renovat, dividit, unit, alit." Crebillon, then director of the Parisian stage, was far less tolerant towards the f Mahomet ' than the Roman pontiff had been, and prohibited the repre- sentation of the play for ten years, when D'Alembert (in 1751), named by D'Argenson to examine it, VOLTAIRE. 35 reported in its favour with a courage wholly to be expected from him. The success of the piece was great, but, like ' Alzire,' it has not retained its place on the stage. Many of his other pieces were damned from the first. This was the fate of 'Artemire,' the second which he produced ; but he changed it in some particu- lars, and it had a great success under the name of ' Mari- amne,' as indeed ( Zaire' itself had been the substitute for ' Eryphyle,' which failed. 'Adelaide,' in like manner, failed, and c Gaston de Foix,' its substitute, had some success. The failure was owing to a jest passed on one of the passages much admired by critics. When Vendome exclaims, " Es tu content, Couci ?" a wag in the pit cried — u Couci-couci," the French for so-so, or indifferent. A similar practical joke had for a while en- dangered the performance of ' Mariamne' — some one, on the Queen drinking, cried out " La Heine boit" The panegyrists of Voltaire dwell on these and similar anecdotes, to account for the loss of many of his pieces, but no play of real merit was ever thus destroyed. Many, also, praise the construction of some of them, and dwell especially upon the excellence of the plots. But the theatrical hell is paved with good designs ill executed, as well as the other. As for the comedies of Voltaire, they are wholly to be rejected : the utmost praise to which they can aspire is as pieces de societe. They were indeed very little played at any time, except in private parties. The best is the ' Ecossaise,' which never was played at all. It is a bitter satire on Freron, under the name of Frelon (hornet), a profligate, mercenary, libeller, D 2 36 VOLTAIRE. who, like some of his vile tribe in our own day, earned a miserable subsistence by selling the venom of his pen to the cowardly malice of some, and his forbearance to the less malignant but as despicable timidity of others. The ' Enfant Prodigue' had considerable success, being played, it is said, nearly thirty times ; but it was never known to be Voltaire's till he claimed it some years after. It is his most elaborate attempt in comedy, being a piece in five acts. Its verse, in five feet (or ten syllables), was an innovation, and apparently was not relished. Thus, if the distance were less which separates Vol- taire's tragedies from the rude and awful grandeur of the ( Cid,' and the exquisite pathos and perfect harmony of the ' Phedre' and ' Athalie,' he would still be, on the comparison, left far behind Corneille, whose ' Menteur,' and Racine, whose * Plaideurs,' continue to keep their place in the line with the comedies of Moliere him- self, though the former is partially imitated from the Spanish, and the latter from the Attic stage.* The 'GEdipe,' which was first performed in 1718, was followed in 1722 and 1724 by the ' Artemire' and ' Ma- riamne,' of which mention has been made, and the poem of the ' Ligue ' was finished and published in the latter year, and afterwards given under the name of the ' Henri- ade.' To this work may be applied the same observation which the dramatic poetry of the author gives rise to, —it is beautifully written — it abounds in fine descrip- tion, in brilliant passages of a noble diction, in senti- * The * Wasps' of Aristophanes, a satire on the Athenian special jurymen. VOLTAIRE. 37 ments admirable for their truth, their liberality, their humanity, — its tendency is to make fanaticism hateful, oppression despicable, injustice unbearable ; but it is the grand work of a philosopher and a rhetorician, more than the inspiration of a poet. No one ever ventured upon a comparison of this epic with the ' Iliad ' or the ' Odyssey ;' the '^Eneid' has been reckoned to present more facilities of approach, but at how great a distance does it leave the ( Henriade ! ' Even Lucan, if less tender, is far more majestic ; Tasso has, in every one essential quality, immeasurably surpassed Vol- taire ; with Milton he will not bear to be named, far less compared ; and Dante, little epic as he is, has more touches of the poetic fire, more inimitable pic- tures drawn with a single stroke, more appeals to our feelings of horror, wonder, and even pity, in a single canto, than can be found in the whole ten of the ' Hen- riade.' There abounds in the poem fine writing, smooth versification, noble ideas, admirable sentiments — but poetry is wanting. The objection made by all, or nearly all critics, that the plot is so clumsily framed as to make the hero a subordinate person for nearly the first half, and to place over his head as his sovereign and master one of the most despicable and even disgusting voluptuaries that ever reigned in mo- dern times, is perhaps not altogether well grounded, though it has some foundation. Although the first in rank, Valois (Henry III.) is a cipher, while his successor is the person actively employed in the conduct of affairs ; and were the last a sort of mayor of the palace, the objection would lose its whole force : but Valois is not at all a roi faineant; we are called 38 VOLTAIRE. upon to recognise his existence and his acts ; we are even required to feel for him when he falls by the hands of an assassin ; to accomplish his destruction the spirits Discord and Fanaticism are evoked from hell ; the form of Guise, whom Valois had murdered, is assumed, and the King expires uttering a speech calculated to excite great interest in his fate. This, however, must be reckoned as the least of the objections to which the poem is exposed ; nor is the want of scenes surrounded with peril to try the hero's courage, nor even the feeble and unskilful manner in which the great event of the piece, Henry's conversion to obtain the crown, the most fatal defect. The piece is without dramatic interest ; the characters are not sustained in action, still less in speech — indeed there is hardly any speaking in the poem. It is truly singu- lar to find a writer, whose forte as a poet lay in dramatic composition, almost entirely abandon his stronghold when he comes to compose his epic. The action proceeds, but it proceeds by way of narrative. The characters are unfolded, but it is by the descrip- tions of the author, not by their own words. Indeed there are very few characters brought forward, and scarcely any but the hero himself bear their parts in the action. Want of fine metaphors, and penury of figurative expression, have been always imputed to it ; and though there is no lack of similes, these are not very happy. But the cardinal defect is that the author appears perpetually before us ; it is a history rather than a poem — a history in numerous verse, and beautifully composed, but not more dramatic, and certainly less beautifully composed, than many passages of Livy, and VOLTAIRE. 39 some of Sallust. The objection made to the intro- duction of philosophy, as having no warrant from the ancients, is hypercritical, beside being incorrect ; Vir- gil's cosmogony in the sixth ^Eneid afforded a prece- dent, if, in a modern poem, any were wanting. The same answer may be given to the cavil against his giving characters of persons introduced. Even Virgil has a few touches of this kind, and Lucan largely uses his moral pencil. But however admirable these passages of the ' Henriade,' and how easily soever we may be disposed to admit them as legitimate, they are exceptionable, as the only means on which the poet relies for bodying forth his conceptions. Again and again the remark occurs ; we take the whole of the portraits and of the action from the artist, and not from the actors. If the failures are signal in great passages, such as called for the full exertion of the poet's power — for example, the St. Bartholomew, and the famine ; the death of Coligny in the former being altogether tame, with the exception of the lines which represent him as a king adored by his people, while his assassins, awe-struck by his presence, kneel before him ;* the latter being described by words conveying general ideas of suffering or of disgust, not by things ; and the pic- ture of the infernal Catherine de' Medicis receiving Coligny's head,f — if the failure be still more signal in * " Et de ces assassins ce grand homme entoure', Semblant un roi puissant par ses peuple adore." — (ii. 219.) •f " Medicis le regut avec indifference, Sans paraitre jouir du fruit de sa vengeance, Sans 40 VOLTAIRE. the denouement, Henry's conversion operated by an address of St. Louis to the Almighty, in which, for- getting Massillon's celebrated exordium to Louis XIV.'s funeral sermon, the Saint is actually made to call the hero "Le Grand Henri? — nay, if the details of that conversion are so described as to make it almost appear that Voltaire is laughing in his sleeve,* we must allow the very great beauty of other passages. The description of the Temple of Love, with which the ninth canto opens, is rich and splendid ; the pic- ture of St. Louis descending to stay the conqueror's hand in the sixth ; the characters drawn so finely and forcibly in the seventh, especially those of Richelieu and Mazarin; the more concise traits by which he paints Guise in the third — " Connaissant ses perils, et ne redoutant rien, Heureux guerrier, grand prince, et mauvais citoyen ;" and Morney in the sixth — " II marche en philosophe, ou 1'honneur le conduit, Condamne les combats, plaint son maitre, et le suit ;" — these are all of the very highest excellence in their kind, though that kind is not epic, hardly poetical. So are such passages of profound sense as the strains of the immortal choir in the seventh canto, — strains " which each star repeated in its course," — Sans remords, sans plaisir, maitresse de ses sens, Et comme accoutumee a de pareil encens." — (ii. 242.) * See particularly x. 480, et seq. — This passage contains the line on transubstantiation which Marmontel admires so much as to pro- nounce that curse of Fenelon against those who are not moved by VOLTAIRE. 41 " A ta faible raison garde-toi de te rendre, Dieu t'a fait pour 1'aimer, et non pour le comprendre ; Invisible a tes yeux, qu'il regne dans ton coeur, II confonde 1'injustice, il pardonne a 1'erreur ; Mais il punit aussi toute erreur volontaire, Mortel ouvre les yeux quand son soleil t'eclaire !" But the finest of all these extraordinary passages are such as in the same Canto, by far the finest of the poem, paint not merely by abstract ideas and by verbose descriptions, but by strokes of genuine poetry, the fiend of Envy : — " La git la sombre Envie, a Frail timide et louche, Versant sur des lauriers les poisons de sa bouche ; Le jour blesse ses yeux, dans 1'ombre etincelans, Triste amante des morts, elle hait les vivans." " Pale Envy see, with faltering step advance, With look suspicious, indirect, askance, With eyes that quiver and abhor the light, But flash with fire and sparkle in the night : She pours her venom o'er each laureled head, Hates all that live, sad lover of the dead." Of Pride :— " Aupres d'elle est 1'Orgueil, qui se plait et s'admire." Of Weakness : — " La Faiblesse au teint pale, aux regards abattus : Tyran qui cede au crime et de*truit les vertus." " Weakness, with paly hue and downcast eyes, Under whose iron rule vice thrives and virtue dies." the famous couplet in the first Eclogue, " Fortunate senex," &c., " Malheur a qui n'est pas emu en le lisant." I fear many a reader lies under this anathema. The verse is — " Et lui decouvre un Dieu dans un pain qui n'est plus." " And in a loaf that is no more reveals a God." 42 VOLTAIRE. Of Ambition : — " Sanglante, inquiete, egaree, De trones, de tombeaux, d'esclaves entouree." " Restless, bloodstain'd, all perils wildly braves, Stalks among thrones, and sepulchres, and slaves." Of Hypocrisy : — "La tendre Hypocrisie aux yeux pleins de douceur : Le ciel est dans ses yeux, 1'enfer est dans son cceur." " The tender creature's eyes with sweetness swell : Heaven 's in those eyes, and in her heart is hell." Nor is the song of these furies, on seeing Henry approach their impious troop, without the highest merit : — " Quel mortel, disent-ils, par ce juste conduite, Vient nous persecuter dans 1'eternelle nuit ?" These are passages of true poetry ; they even approach the seventh Canto to the sixth book of the ' ^Eneid/ It may be questioned if the ideas of making Envy " triste amante des morts" — Feebleness "tyran qui cede aux crimes et detruit les vertus" — and Hypocrisy " tendre," are equalled by any of Virgil's moral pictures. Certainly to all in the eleventh book of the ' Odyssey ' it is beyond doubt immeasurably superior, as indeed is the sixth ^Eneid. Nor can we hesitate to affirm that, had the rest of the e Henriade' been composed in the same poetic spirit, we should not have been suffered with impunity to consider it an elegant history. In the year 1730 Voltaire wrote part of another poern, which he finished at intervals during the seven or eight years following — his too famous mock-heroic, the * Pucelle d'Orleans.' It is painful and humiliating to human genius to confess, what yet is without any VOLTAIRE. 43 doubt true, that this is, of all his poetical works, the most perfect, showing most wit, most spirit, most of the resources of a great poet, though of course the nature of the subject forbids all attempts at either the pathetic or the sublime ; but in brilliant imagery— in picturesque description — in point and epigram — in boundless fertility of fancy — in variety of striking and vigorous satire — all clothed in verse as natural as Swift's, and far more varied as well as harmonious — no prejudice, however naturally raised by the moral faults of the work, can prevent us from regarding it as the great masterpiece of his poetical genius. Here of course the panegyric must close, and it must give way to indignation at such a perversion of such divine talents. The indecency, often amounting to absolute obscenity, which pervades nearly the whole compo- sition, cannot be excused on the plea that it is only a witty licentiousness, instead of one which excites the passions ; still less can it be palliated by citing bad pre- cedents, least of all by referring to such writers as Ariosto, who more rarely violates the laws of decorum ;* * In some of the author's correspondence he is fond of referring to indelicate passages of other writers in his justification ; nay, even to the plain language used in some parts of the Old Testament. This flimsy reason is at once put to flight by Sir Joshua Reynolds's illustra- tion of the nakedness of the Indian and the prostitute. But it is worth while to observe how carefully the first and greatest of poets avoids all cause of blame in the passages where he is brought towards the verge of indecency. The Song of the Bard, in the 8th Odyssey, where Vulcan's discovery of Mars and Venus is related, is the most remarkable of these ; and the jocose talk of Apollo and Mars on the subject savours somewhat of ribaldry. But see the short and simple expressions used, and mark that nothing is liquorishly dwelt on : — *£lg TO. Trpwra yuiyrjffav f.v 'H^aioroio fiopoiffir. — (viii. 269.) And— 44 VOLTAIRE. whereas Voltaire is ready to commit this offence at every moment, and seems ever to take the view of each sub- ject that most easily lends itself to licentious allusions. But this is not all. The ' Pucelle' is one continued sneer at all that men do hold, and all that they ought to hold, sacred, from the highest to the least important subjects, in a moral view — from the greatest to the most indifferent, even in a critical view. Religion and its ministers and its professors — virtue, especially the virtues of a prudential cast — the feelings of humanity — the sense of beauty — the rules of poetical compo- sition — the very walks of literature in which Voltaire had most striven to excel — are all made the constant subjects of sneering contempt, or of ribald laughter ; sometimes by wit, sometimes by humour, not rarely by the broad grins of mere gross buffoonery. It is a sad thing to reflect that the three masterpieces of three such men as Voltaire, Rousseau, Byron, should all be the most immoral of their compositions. It seems as if their prurient nature had been affected by a bad but criminal excitement to make them exceed themselves. — Assuredly if such was not Voltaire's case, he well merits the blame ; for he scrupled not to read his ' Pucelle' to his niece, then a young woman.* And— Avrop £ywv evdoipi irapa xpvffirl Aippodiny. — (viii. 342.)

GREATLY distinguished as the people of Great Britain had ever been for their achievements in all the other walks of literature and science, it is certain that there never had appeared among them any historian of emi- nence before the middle of the eighteenth century. The country of Bacon, of Newton, of Locke, of Napier — the country of Milton, of Shakspeare, and Buchanan — of Dryden, Swift, Bolingbroke — had as yet nothing more to produce as the rival of ancient historical fame than the crude and partial annals of Buchanan, great only as a poet, and the far more classical and less prejudiced political Memoirs rather than ' History ' of Clarendon. While Italy had her Davila and Guicciardini, and France her Thuanus (Du Thou), this island was nearly unknown for any native annals, and a Frenchman (Rapin de Thoyras) had provided the only ' History of England ' which any one could find readable, nor in reading that could he affect to find pleasure. It was reserved for two natives of Scotland to remove such an unhappy peculiarity, and to place our fame in this important walk of literature upon a level with our eminence in all its other depart- ments. Mr. Hume first entered the field ; and though his is by no means the work on which the historical o 2 196 HUME. merit of the country mainly rests (for he had neither the impartiality nor the patience of the historical office), yet he is decidedly to be praised as having been the first to enter the field with the talents of a fine writer, and the habits of a philosophic inquirer. David Hume was born at Edinburgh, in April, 1711. He was the younger son of Mr. Hume of Ninewells, in the county of Berwick, and related to Earl Hume's, or Home's, family ; his mother was the daughter of Sir David Falconer, Lord President, arid niece of Lord Halkerston, one of the Judges, of the Court of Session. His father dying soon after his birth, his guardians intended him for the bar ; but he tells us that while " he was supposed to be poring over Voet and Vin- ning, he was secretly devouring the pages of Cicero and Virgil." He neglected Greek in his early years, and had to make up for this deficiency, with some labour, in after life. The fortune of his father, to which his eldest bro- ther Joseph succeeded, was inconsiderable ; and his own portion being necessarily very small, it was deemed expe- dient, as he refused to be a lawyer, that he should exert himself in some other way to provide for his support. He was therefore sent to a mercantile house at Bristol, in 1734 ; but he found the drudgery of this employ- ment intolerable, and he retired to Rheims, in the north of France, determined, while he prosecuted his favourite studies, to supply, by rigorous economy and a life of abstinence, the want of fortune. From Rheims he removed to La Fleche, in Anjou, and there wrote his 'Treatise on Human Nature/ It was pub- lished in 1737, and fell, as he says, still-born from the HUME. 197 press. He afterwards distributed it into separate ' Essays/ which, with additions, he published in 1742, and it had more success. After his first publication he retired to his bro- ther's house, and lived so happily there among his books that he afterwards says, in a letter to Dr. Robert- son, that he should never have left it, had not his brother's marriage made a change in the family. Although he appears to have felt much more and much earlier than Robertson the love of literary fame, his first work having been published when he was only 26, while the ' History of Scotland ' only appeared in the author's 38th year, yet manifestly the same love of literary pursuits for their own sake, the desire of knowledge, the indulgence of a speculative turn, and meditating on the events of past times and on the sys- tems of former inquirers, appears to have been the mainspring of both their movements ; and Hume was happy in being allowed to gratify these strong pro- pensities of his nature. The last Marquess of Annandale was a person of weak intellect. Though neither insane nor idiotic, he required the company of a friend, as his imbecility ex- cluded him from society, and he was not ill enough to require the care of a keeper. Mr. Hume, in 1745, ac- cepted this situation, as a large salary was very natu- rally given to induce him. But after a year's resi- dence, finding, as we see from the late publication of some querulous letters very little like his ordinary cor- respondence, that he could no longer submit to such a life, he left this occupation, and was fortunate enough to receive an invitation immediately after of a very different 198 HUME. kind. It was to attend, as private secretary, General St. Clair (uncle of Lord Loughborough, and great- uncle of the late Lord Rosslyn), whose family has always been honourably distinguished by their love of literary society. The General was appointed to com- mand an expedition, at first destined for the conquest of Canada, but afterwards very unwisely, and with no result any more than any rational design, diverted to the folly of making an incursion on the coast of France. The following year, 1747, he accompanied the General on his embassy to the courts of Vienna and Turin. This mission was of a military nature, and the philosopher tells us that he was not only Secretary, but Aide-de-camp, with two military men — Captain, afterwards General, Grant, and Sir Henry Erskine, afterwards a General officer also, and who mar- ried the Ambassador's sister. These two years, 1746 and 1747, formed the only interruption ever given to his studies ; but they appear to have satisfied him in one important particular ; for, "not only," he says, " I passed this period of time agreeably and in good com- pany, but my appointments with frugality had made me reach a fortune which I called independent, though most of my friends were incited to smile when I said so ; in short, I was now master of near a thousand pounds." While he was at Turin, his ' Inquiry concerning the Human Understanding' was published in London. It was the ' Treatise on Human Nature' presented in a new form, and was not much more successful than its pre- decessor ; but he nevertheless began to perceive symp- toms of his books coming into notice ; " for," says he, HUME. 199 " I found, by Dr. Wai-burton's railing, that they are beginning to be esteemed in good company." Return- ing to Scotland, he again resided with his brother, and wrote his ' Political Discourses/ which were published in 1752, and immediately excited much attention. " The work was/' he says, " well received both at home and abroad." But he published, the same year, the ' Inquiry concerning the Principles of Morals/ which " came/' he says, " unnoticed and unob- served into the world ;" though he adds, that " in his own opinion it is incomparably the best of all his writings, historical, philosophical, or literary." It is plain, then, that neither in their original forms of trea- tises, forms three times varied, nor when broken down into separate essays, did his metaphysical and theo- logical speculations succeed so far as even to obtain any attention. This is the more surprising, that beside the great ingenuity and novelty of some theories which they contain, they are tinged through- out with an excessive scepticism upon all subjects of a religious nature, and upon some with an openly pro- fessed unbelief, which might have been expected to ex- cite indignation, and so rescue the writings from neglect. The ' Essays, Moral and Metaphysical/ are the form in which we now read these speculations, and a life of Hume which should not speak of their merits would be imperfect, as they certainly have long obtained the full share of celebrity which was at first denied them. To refuse these well-known Essays the praise of great subtilty, much clever argument, some successful sarcasm, and very considerable originality, is impos- 200 HUME. sible ; but a love of singularity, an aversion to agree with other men, and particularly with the bulk of the people, prevails very manifestly throughout the work ; and we may recollect that it is the author's earliest pro- duction, the 'Treatise on Human Nature/ which formed the basis of the whole, having been written before his six and twentieth year, at an age when the distinc- tion of differing with the world, the boldness of attacking opinions held sacred by mankind at large, is apt to have most charms for vain and ambitious minds. Accordingly, he finds all wrong in the opinions which men generally entertained, whether upon mo- ral, metaphysical, or theological subjects, and he pushes his theories to an extreme point in almost every instance. Thus, that we only know the con- nexion between events by their succession one to ano- ther in point of time, and that what we term causa- tion, the relation of cause and effect, is really only the constant precedence of one event, act, or thing to another, is now admitted by all reasoners; and we owe to Mr. Hume the discovery, it may be well called, of this important truth. But he will not stop here : he must deny that there can be such a thing as one act, or effect, or event causing another : he must hold that there can be no such thing as causation, no such thing as power ; he must discard from our belief those ideas which all men in all ages have held so distinctly, and so universally, as to have given them names, specific appellations, in all languages. He denies all connexion, all influence, all power, and holds it impossible that any such things should be — that any rational meaning should belong to such words. HUME. 201 — In like manner, every one is ready to admit the solidity of the distinction which he takes between the impressions of memory and those of imagination. But this won't satisfy him ; he will have all belief to con- sist merely in this difference, and that we only believe or disbelieve any thing or any event according as our minds have a more or less vivid idea of it from memory, or from sensation, than from imagination. — In like manner, while no objection could be taken to his holding that a miracle is, prima facie, to be regarded incredible, because it is much more likely, and much more according to the laws of nature, that human tes- timony should deceive us, even that men's senses should delude them, than that those laws should be sud- denly and violently suspended, yet he will not be satisfied unless we go a great step farther, and admit not merely the improbability but the impossibility of miracles, as if the weight of testimony never could be so accumulated as to make it more unlikely, more a miracle, that it should be false, than that the alleged deviation from the laws of nature should have taken place.* Indeed, had he lived to see the late discoveries in Fossil Ostelogy, he would have been placed in a complete dilemma ; for these plainly show, that at one remote period in the history of the globe there was such an in- terposition of creative power as could alone form man and other animals not previously existing ; and thus he must either have distrusted the evidence of thousands * In the first part of the ' Essay ' this qualification is introduced, but the second part roundly asserts the absolute impossibility, on the ground of the laws of nature being broken. 202 HUME. now alive, and even of his own senses, the phenomenon being visible daily, or he must have admitted the miracle of creation ; that is, the interposition of a being powerful to suspend the existing order of things, and make a new one. It is by no means correct to affirm, as some do, and Mr. Hume himself among the number, that his writ- ings are only sceptical. Many of them amount merely to doubts ; but some, under the mask of doubts, are essentially dogmatical. Indeed, some of his specula- tions are upon subjects which cannot be treated scepti- cally ; for the question in these cases being whether we have evidence or not of the position, whoever maintains the negative denies the position. Thus, to take the most important example of all, the argument upon Providence and a Future State is of this very character. The question, and none other equal in im- portance can exercise the human faculties, is, whether we have or not, by the light of nature, sufficient evi- dence to make us believe in a Deity and the Soul's Immortality. His argument is, not that there is any doubt on the subject, but that we have no such evi- dence; consequently his position must be that there is no ground for believing in a God or a Future State. It is easy to say Mr. Hume was not an atheist ; and that neither he nor any man can in one sense of the word be an atheist is certain. If by denying a God we mean believing that his non-existence is proved, there neither is nor can be an atheist, because there cannot possibly be conceived any demonstration of that nega- tive proposition. To prove that a man asserted to be in existence, exists not, we must either show that he once existed, and has ceased to exist, or that he never HUME. 203 existed, but more certainly the former than the latter, because the former alone can be considered to leave the proposition quite certain. Now, clearly this kind of proof is inconceivable as to a Deity ; consequently no man in this sense can be an atheist, if his under- standing be sound. But we really mean by atheist as contradistinguished from sceptic, one who holds that there exists no evidence of a Deity, as contradistin- guished from him who only entertains doubts on the subject — doubts whether there be evidence or no. Mr. Hume's argument, if solid, shows that there is no evidence, and not that there are doubts : consequently the inference from his argument is, not that we have reason for doubting whether or not there is proof, but that we have no proof, and, therefore, if consistent with ourselves, admitting his argument, we must not believe; that is, we must disbelieve. In the ordinary sense of the word, and as far as it is possible for the thing to exist, this is atheism, not scepticism. On miracles, no one has ever contended that the author's doctrine amounted only to scepticism. He does not doubt at all — he denies, and not only denies negatively that any miracle was ever proved by evidence, but affirms positively that none ever can be so proved. His whole argument goes to this ; and between the impossibility of a miracle ever having been performed, and the total want of evidence of a Deity by the light of nature, we are left not to doubt, but to deny both providence and a future state. The one argument shows supernatural evidence to be impossible ; it shuts out light from above : the other shows natural evidence to be non- existent; it shuts out light from the world around 204 HUME. us. The two together amount to plain and practical atheism, as far as such a belief is compatible with sanity of mind. Of the * Political Discourses* it would be difficult to speak in terms of too great commendation. They combine almost every excellence which can belong to such a performance. The reasoning is clear, and unin- cumbered with more words or more illustrations than are necessary for bringing out the doctrine. The learning is extensive, accurate, and profound, not only as to systems of philosophy, but as to history, whether modern or ancient. The subjects are most happily chosen ; the language is elegant, precise, and vigo- rous ; and so admirably are the topics selected, that there is as little of dryness in these fine essays as if the subject were not scientific ; and we rise from their perusal scarce able to believe that it is a work of phi- losophy we have been reading, having all the while thought it a book of curiosity and entertainment. The great merit, however, of these discourses, is their originality, and the new system of politics and politi- cal economy which they unfold. Mr. Hume is, beyond all doubt, the author of the modern doctrines which now rule the world of science, which are to a great extent the guide of practical statesmen, and are only prevented from being applied in their fullest extent to the affairs of nations, by the clashing interests and the ignorant prejudices of certain powerful classes ; for no one deserving the name of legislator pretends to doubt the soundness of the theory, although many hold that the errors of our predecessors require a slow recourse to right principle in conducting the practical business of HUME. 205 the world. The peculiar felicity of the author in distri- buting his doctrines as the subjects of separate essays, whereby he avoided the repulsive forms of a treatise, and yet moulding these separate treatises into one body and one harmonious system, cannot be too much admired. We read them as different and as short works on various subjects ; but we perceive at each step that we are guided by the same genius, — that one spirit of inquiry pervades the whole — one view of human society and of national interests is taken throughout — one sagacious unfolder of truth, one accurate and bold discoverer of popular error, is at work in each discourse ; and it is certain that Dr. Smith's celebrated work, with all its great merits, is less of a regular system than the detached essays of Mr. Hume. The originality of the latter's opinions is wholly undeniable : they were published full fourteen years before the ' Wealth of Nations.' As for his 'Inquiry concerning the Principles of Morals,' of which he had himself formed so high an estimate, this is indeed a very excellent work, and ap- pears well to deserve the opinion pronounced upon it by the author, although his 'Political Discourses* may be superior in the originality and importance of their views. But the composition of the ' Inquiry ' is more careful and better elaborated than that of his other philosophical writings, at the same time that it loses none of the ease or grace by which his man- ner is always so remarkably distinguished. There is in this treatise a copiousness and felicity of illus- tration rarely anywhere else to be found ; and it is full of learned allusions and references, showing 206 HUME. the various and extensive reading in which he had indulged. Nor is it the least remarkable fea- ture of the work, that though preferred by him before all the other productions of his genius, it contains nothing at all even bordering upon scep- tical opinions. On the contrary, he reprobates the selfish system of morals, and is a strenuous advocate of that which recognises the benevolent feelings, and traces human conduct to a desire of enjoying their gratification. Of utility he largely states the importance, but rather as one leading motive than as the sole source of either our actions or our judgments upon them ; and assuredly both in this and the other branches of the argument a wider departure from the commonly received standard of morals may be seen in the philo- sophy of Paley than in that of the ' Inquiry/ In the same year that he published the c Poli- tical Essays,' 1752, he was appointed their libra- rian by the Faculty of Advocates. He obtained this place after a very severe contest, in which the ut- most force of the party opposed to his known opinions was brought to bear in favour of his antagonist. The emoluments of the office were not above fifty pounds a-year ; but the violence of the parties was propor- tioned to their zeal for and against the principles of the candidates ; and I find in his unpublished letters curious indications of his anxiety for success, and of his delight at the victory which he gained, chiefly, he says, through the assistance of the younger members of the Scottish bar and of the ladies of Edinburgh. " There is nothing," he says, in a letter to his intimate friend Dr. Clephane, then a physician in London, " since the HUME. 207 rebellion (1745), that ever so much drew the attention of this town, except Provost Stuart's trial ; and there is scarce a man whose friendship or acquaintance I could desire, who has not given me undoubted proofs of his concern and regard." His adversary was Mr. Kenneth Mackenzie, professor of civil law in the University of Edinburgh.* Although the salary of the office which he thus ob- tained was inconsiderable, the situation for a literary man was very desirable. He thus had constant and easy access to an excellent library. This induced him to undertake a work which he thought much wanted, a classical history of England ; but he was afraid of at- tempting it on so extensive a scale as to begin at the earliest period, and continue it for seventeen cen- turies ; and he therefore confined himself at first to the Stuarts, commencing with the accession of James I., and closing with the expulsion of his grandson James II., at the revolution of 1688. This work made two volumes, of which one was published in 1754, and another in 1756. He entertained a sanguine expecta- tion that his first volume, containing the reigns of James I. and Charles I., would have met with a favour- able reception ; and we find the grounds of his con- fidence stated in one of his letters to Dr. Clephane. His election was in February, 1752, and in the follow- ing January he must have made great progress ; for he thus describes his having already consulted his friends * It is singular that a contest and a victory which once so much occupied him, and which he regarded as the battle and the triumph of his free opinions over bigotry, is not even glanced at in his ' Life* of himself. 208 HUME. upon his performance : — " As there is no happiness," he says, " without occupation, I have begun a work which will employ me several years, and which yields me much satisfaction. Tis a history of Britain, from the union of the crowns to the present time. I have already printed the reign of King James. My friends flatter me (by this I mean that they do not flatter me) that I have succeeded. You know that there is no path of honour on the English Parnassus more vacant than that of history. Style, judgment, impartiality, ease, every thing is wanting to our historians ; and even Rapin, during his latter period, is ex- tremely deficient. I make my work very concise, after the manner of the ancients. It divides into three very moderate volumes — one to end with the death of Charles I., the second at the Revolution, the third at the Accession, 1714; for I dare come no nearer the present times. The work will neither please the Duke of Bedford nor James Frazer, but I hope it will please you and posterity." — " I was, I own," he says in his account of his life, " sanguine in my expectations of the success of this work. I thought I was the only historian that had at once neglected present power, interest, and authority, and the cry of popular prejudices ; and as the subject was suited to my capacity, I expected proportionate success." But whatever might be the want of such a work, and how much soever he relied on his superior qualifi- cations for the task, he was doomed to a bitter dis- appointment. " I was assaulted," says he, " by one cry of reproach, disapprobation, and even detestation. English, Scotch, and Irish, Whig and Tory, church- HUME. 209 man and sectary, freethinker and religionist, patriot and courtier, united against the man who had pre- sumed to shed a generous tear for the fate of Charles I. and the Earl of Strafford." But the singularity of the case, and the great mortification of the author, was this : that with all the universal clamour, all the storm did not save him from neglect ; it subsided as quickly as it had been raised, and the ' History' sunk into oblivion. In a year's time, only five and forty copies were sold, at least in London ; and although he tells us in another letter, that " at Edinburgh no book was ever more bought, or furnished more subject of conversation," yet in London it was other- wise. The author's discouragement was great; he was disgusted with belonging to a country so subject to the tyranny of faction and the clamours of the mob, while it boasted so constantly, and blustered so loud- ly, about its liberties: he even entertained serious thoughts of leaving it for ever, changing his name, and passing the rest of his days in some French pro- vincial town, far from those braggarts and intolerant brawlers. Nor does he appear to have been deterred from this project, excepting by the obstacles to its execution which the war, breaking out immediately after, interposed. The only encouragement which he received under his disappointment was from the two Primates, Herring and Stone, who approved of the book, and sent him messages, bidding him not to be cast down by the temporary failure. During the interval between the first and second volume appeared his 'Natural History of Religion,' which so far attracted notice, that Bishop Hurd wrote 210 HUME. an answer to it ; and about as elegantly feeble as might be expected from that moderate prelate, unless that some part of it came from the more haughty and vigorous pen of his patron Warburton, and redeemed the tract from the imputation of candour, toleration, and temper. The second volume of the ' Stuarts ' " hap- pened to give less offence to the Whigs than the first," he says, " and being therefore somewhat better received, helped to buoy up its unfortunate brother." Three years after he published the ' House of Tudor,' which con- taining his account of ecclesiastical matters in Eliza- beth's reign, and of Queen Mary's conduct, revived the clamour raised against the first volume, and, like that, was soon neglected and forgotten. In 1761 he finished the work by publishing the two volumes con- taining the earlier history : " they had," he says, " tole- rable, and but tolerable, success." It is, however, also stated by him, as an indication of growing popularity, that all the clamour and all the neglect did not prevent the booksellers from giving him more money when they purchased the copyrights than had ever before been paid in England ; so that, with his sober habits and moderate desires, he was become not only inde- pendent, but opulent. It is to be observed that, for his ' History of Scotland,' Dr. Robertson had only received 600/., the publishers having cleared 600Q/. For ' Charles V.' he received 3,600/., and for ' America* 2,400Z. (being in the same proportion), while, no doubt, 50,000/. at the least must have been realised by those works. In considering the merits of the c History of Eng- land/ we must first of all observe upon the great HUME. 211 difference which appears between the pains bestowed upon this celebrated work and those which the rival historian was wont to bestow upon his writings. Dr. Robertson's ' Scotland/ consisting of about a volume and a half (for the rest of the second volume is com- posed of original documents printed as an appendix), occupied his almost undivided attention for above six years.* Hume's first volume could not have been the work of above a year or fifteen months ; for it was begun when he went to the Advocates' Library early in 1752, and it was published in 1754. The second volume succeeded in 1756, but he had written half of it when the first was published ; and in 1755 there appeared also his ' Natural History of Religion.' Con- sequently we are positively certain that he wrote more of his 'History' in less than two years than Dr. Robertson wrote of his in above six ; and that his whole ' History of the Stuarts ' could not have taken above three years to prepare and to write. It is impossible to doubt that this mode of writing history must leave no room for a full investigation of facts and weighing of authorities. He had no right to number "care" among the items of superiority to his predecessors, upon which he had plumed himself in his letter to Dr. Clephane. The transactions of James's time com- prised perhaps the most important period of our constitutional history, because the struggle between * Though by his letter to Lord Hailes he seems only to have begun it in 1742, yet I have heard his eldest sister often say that he had a whole room full of books to read or consult for some time before at Gladsmuir, where she lived with him. p2 212 HUME. the Crown and the Commons then began, and occu- pied the greater part of his reign. It was impossible to examine the period too closely, or in too minute detail. The struggle continued in Charles's time, and ended in the quarrel between the King and the people, in the usurpations of the Parliament, and in the over- throw of the Monarchy. The Commonwealth then followed, and the Cromwell usurpation. Now there is hardly one passage in all this history, from 1600 to 1650, which is not the subject of vehement controversy among parties of conflicting principles, and among inquiring men of various opinions ; yet all this was examined by Mr. Hume in less than two years, and his history of it was actually composed, as well as his materials collected and his authorities investigated and compared and weighed, within that short period of time. No one can be surprised if, in so short a time allotted to the whole work, far more attention was given to the composition of the narrative than to the preparation of the materials. It was altogether im- possible that, in so short a period, the duty of the historian should be diligently performed. The execution of the work answers to the mode of its performance. But if the ' History ' be not diligently prepared, is it faithfully written? There are numberless proofs of the contrary ; but we have the most express evidence in the author's own statement to prove this position. The temper in which his work was written upon all the constantly recurring points in contest between the two opposing parties may be judged of with accuracy, and towards himself with perfect justice, by the avowal which he makes respecting the alterations introduced HUME. 213 after the first publication. " Though I had been taught," he says> " that the Whig party were in pos- session of bestowing all places, both in the State and in literature, I was so little inclined to yield to their senseless clamour, that in above a hundred alterations, which further study, reading, or reflection, engaged me to make in the reigns of the two first Stuarts, I have made all of them invariably to the Tory side." We have here indeed a double confession. To the first volume is confined the reign of the first two Stuarts, and to that consequently is this remarkable admission limited. Now, if that volume had been written with any " care," could subsequent reading and reflection have suggested above a hundred alterations, all admitted to be material, by the statement that they affected the complexion of the political opinions conveyed in those passages ? But again, if the author's mind was in a state of impartiality when he thus finally com- posed his book, how could it happen that every one of his corrections should be on one side, and not a single correction on the other, unless he had written the work originally with a strong bias towards the Whig side, instead of which his bias is, on all hands, allowed to have been strongly the other way ? The ' History of the Tudors' has the same cardinal imperfection of carelessness and haste, but in a lesser degree, because he had fewer controverted points to con- sider, and a smaller mass of authorities to examine. He had also less temptation to give his narrative and reflec- tions a bias from the leaning of his opinions, because, excepting the questions relating to Mary Queen of Scots, there are few passages from Henry VII. to 214 HUME. Elizabeth subject to much controversy between the Whig and the Tory parties. The earlier period before the Conquest, and from the Conquest to Richard III., is wholly free from questions of this description ; but also it must be observed that the historian's diligence did not increase as he approached the termination of his labours ; the Anglo-Saxon history is in every respect the most meagre and superficial part of the whole work. We shall afterwards see how his friends explained this inferiority (Life of Robertson). The bias of Mr. Hume's mind, from which his chief partialities proceed, was the prejudice which he had conceived against Whig, and generally against popular, principles. This arose, in great part, from his con- tempt of vulgar errors, and his distrust of the more numerous and ignorant classes of the community, whom those errors chiefly may be supposed to affect. His acquaintance with antiquity, too, had not tended to lessen his belief of the giddiness and violence of mul- titudes when they interfere directly in the conduct of affairs. To these considerations must certainly be added the connexion between the Whig party in the State and the fanatical party in the Church. The Roundheads were religious bigots in his eyes, and were, in fact, deeply tinged with superstition ; and they were the original of the Whigs both in England and in Scotland. The Cavaliers held cheap all such ob- servances, regarding religious enthusiasm with mingled dislike and derision ; and from them came the Tories in both parts of the island. Nor was the connexion merely genealogical or historical. As late as the times of Addison and Bolingbroke, we find the friends HUME. 215 of the Hanoverian succession distinguished by their respect for religion, and the Jacobites chiefly giving in to the fashionable deism, or the latitudinarian princi- ples, of Catholic countries in modern times. A contempt of popular rights, a leaning towards power, a proneness to find all institutions already established worthy of support, a suspicion of all mea- sures tending towards change, is thus to be seen pre- vailing through Mr. Hume's reflections, and influencing both his faith in historical evidence and his manner of conducting the narration of facts. A bias of the like kind is plainly perceptible in his remarks and in his recital, wherever the Church, the sects are concerned, and generally wherever religion forms the subject of either. Independent of the testimony which he has un- wittingly borne against himself, in respect of his Tory partialities, the proofs of his perverting facts, especially in the last two volumes of his work, have been multiplied by the industry of succeeding historians, till the discre- dit of the book, as a history, has become no longer a matter of any doubt. It is of no avail that he himself and his admirers cite the disrepute and even odium into which his account of the Stuarts fell with the Jacobites, as much as with the Whigs, from its first appearance. That party's unreasonable demands upon our faith would be satisfied with nothing short of absolutely acquitting all the Stuarts of all guilt and of all indiscretion ; and they probably felt more disappointed, because they were certainly more injured, by the admissions of one mani- festly ranged on their side, when he was compelled to stop short of their pure and perfect creed. Afterwards the Tudor history completed their discontent ; but it 216 HUME. affords no proof whatever of his impartiality. He had, of course, far too much sense and too penetrating a saga- city to doubt the guilt of Queen Mary during the Scot- tish portion of her life, admitted as the greater part of the charges against her were, by her own conduct in the open profligacy of her connexion with her husband's murderer ; and the prejudice which this unavoidable conviction raised in his mind, extended itself to the more doubtful question of her accession to Babing- ton's conspiracy, a question which he appears to have examined with much less patience of research, though it belonged to his own subject, than he had applied to the Scottish transactions of the queen, which, in their detail at least, had far less connexion with his work. If patient investigation of the subject be a merit — and next to fidelity it is the chief merit of history — Mr. Hume's work is here most defective. The time taken to compose it sufficiently proves this, as has already been shown ; but there is continual proof that he took what he found set down in former works without weighing the relative value of conflicting au- thorities, and generally resorted to the most acces- sible sources of information. There have been in- stances without number adduced of his inaccuracy in citing even the authorities to which he confined his researches. Nor can we acquit him on another charge not rarely brought against him, and partaking of the two former — neglect or carelessness about the truth, and infidelity in relating it. He loved effect in his narrative, and studied it. Unmindful of the ancient critic's golden HUME. 217 rule, " Historia tanto robustior quanto verier,"* he oc- casionally adorned and enlivened his page by excursions into the field, to the historian forbidden, of fancy; and either perverted or forgot the facts of the true story. Sometimes he overlooked inconsistencies in matters within his own knowledge, as when he made Charles I. be disturbed in his sleep by the erection of the scaffolding for his execution, when he is proved to have known that Charles suffered by cold in the walk across the park from St. James's, where he really slept. J" As for his picturesque description of sudden deaths and female miscarriages being occasioned by the execution, and of equally violent effects produced by the Restora- tion, these appear to be mere fancy pieces, no authority whatever being cited to support them. If from the cardinal virtues of fidelity, research, and accuracy, we turn to the great but secondary accom- plishments of the historian, we can scarcely find ex- pressions too strong to delineate the merit of Mr. Hume. His style is altogether to be admired. It is not surpassed by Livy himself. There is no pedantry or affectation, nothing forced or far-fetched. It flows smoothly and rapidly, according to the maxim of the critic, " Currere debet et ferri." J It seems to have the " lactea ubertas "§ of Livy, with the " immortalis velocitas "|| of Sallust. Nothing can be more narra- * Quinct. ii. 4, 2. •\ His marks are upon Lord Herbert's narrative in the Advocates* Library at Edinburgh ; but he prefers citing Walker's l History of the Independents,' which contains the false statement, although the very next page mentions his coming from St. James's. t Quinct. ix. 4, 18. § Ib. x. 1, 32. || Ib. x. 1, 102. 218 HUME. tive ; the story is unbroken, it is clear, all its parts dis- tinct, and all succeeding in natural order ; nor is any reflection omitted where it should occur, or introduced where it would encumber or interrupt. In both his narrative and his descriptions there is nothing petty, or detailed more than is fit or needful ; there is nothing of what painters call spotty — all is breadth and bold relief. His persons are finely grouped, and his subjects boldly massed. His story is no more like a chronicle, or his views like a catalogue of particulars, than a fine picture is like a map of the country or a copy of the subject. His language is more beautiful and powerful than cor- rect. He has no little tendency to Gallicisms. He has many very inaccurate, some ungrammatical phrases. In this respect he is far behind Robertson. The general effect, however, of his diction is unequalled. He cannot be said to write idiomatic English, being indeed a foreigner in that sense ; but his language is often, nay, generally, racy, and he avails himself of the expressions, both the terms and the phrases, which he finds in older writers, transferring them to his own page. In this he enjoys a great advantage over Robertson, who, resorting necessarily to Latin, or to foreign or pro- vincial authors, could not manage such transfers, and was obliged to make all undergo the digestive and assimilating process, converting the whole into his own beautiful, correct, and uniform style. Another reach of art Hume has attained, and better than any writer in our language : he has given either a new sense to expressions, or revived an old, so as never to offend us by the neology of the one process or by the archaism of the other. With this style, sustained by his pro- HUME. 219 found philosophy, there can be nothing more beau- tiful than some of his descriptions of personal charac- ter, or of public feeling, or of manners, or of individual suffering ; and, like all great masters of composition, he produces his effect suddenly, and, as it were, with a single blow. Who that has read can ever forget his account, fanciful though it be, of the effects produced on the people by Charles's death and his son's return? Or his picture of the French Ambassador at his first audi- ence of Elizabeth, after the massacre of St. Bartho- lomew, proceeding " through the palace, — silence, as in the dead of night, reigning through all the chambers, and sorrow sitting on every face — the courtiers and ladies clad in deep mourning, ranged on each side, and allowing him to pass without affording him one salute or favourable look :" Or Cromwell's state of mind when " society terrified him, surrounded by numerous, unknown, implacable enemies ; solitude astonished him by withdrawing the protection neces- sary for his security :"f Or the groups of great men who subverted the monarchy, when " was celebrated the sagacity of Pym, more fitted for use than orna- ment ; matured, not chilled by age " — when " was displayed the mighty ambition of Hampden, taught disguise, not moderation, from former constraint ; sus- tained by courage, conducted by prudence, embellished by modesty" — when "were known the dark, ardent, and dangerous character of St. John, the impetuous spirit of Hollis, violent, open, and entire in his enmities * Chap. xl. t ChaP- lxii- 220 HUME. and in his friendships ; the enthusiastic genius of young Vane, extravagant in the ends which he proposed, sagacious and profound in the means which he em- ployed, incited by the appearances of religion, negli- gent of the duties of morality."* These are the strokes of a master's pencil, and beauties such as these would make this the first of histories, if the grace of form could atone for the defect of substance ; if the trans- gressions against fidelity and the want of diligence could be covered over by the magical power of diction. The sagacious reflections and spirit of profound phi- losophy must not be passed over ; they are another praise of this work. These rarely fail the author, whether in judging of the connexion and the influence of events ; or in estimating the value of conflicting accounts, where he will give himself the trouble of comparison ; or in noting the errors and the merits of the policy pursued by statesmen. It is to be observed, however, that as in treating of ecclesiastical affairs he generally suffers his peculiar religious opinions to be superseded by the received principles of those rulers whose conduct he describes, and of their subjects ; so does he not often obtrude his sound and enlightened views of public policy, especially of economical science, upon his reader, rather conforming himself to the vulgar errors on the subject, as when he speaks of the balance being for or against a commercial state. Perhaps, too, in ranking Galileo above Bacon he made the same kind of sacri- fice, though certainly his disrespectful remarks on Shakspeare run counter to the critical faith commonly * Chap. lix. HUME. 221 received in England ; and the contempt with which he treats the political writings of Locke and Sidney in his concluding chapter is a sacrifice of his own taste as well as of his reader's feelings to the prejudices of his party. It must be added — because great mistakes have been committed in this matter — that though the whole work was written in too short a time to give an opportunity for investigating the subject, yet the com- position was exceedingly careful, and anything rather than hasty. He is represented as having written with such ease that he hardly ever corrected. Even Mr. Stewart has fallen into the error ;* and Mr. Gibbon commends as a thing admitted the "careless, inimi- table beauties " of Hume's style. It was exactly the reverse, of which evidence remains admitting of no doubt and no appeal. The manuscript of his reign before that of Henry VI., written after the c History of the Stuarts and the Tudors,' is still extant, and bears marks of composition anxiously laboured, words being written and scored out, and even several times changed, until he could find the expression to his mind. The manuscript of his ' Dialogues ' also remains, and is written in the same manner. Nay, his very letters appear by this test to have been the result of care and labour. The rnaxim of Quinctilian — " Quseramus op- timum, nee protinus offerentibus gaudeamus" — seems always to have been his rule as to words ; and his own testimony to the same effect is to be found in a letter which I have obtained. f Certainly it would have been well if he had not adopted the opposite principle as to * Life of A. Smith. f See Appendix. 222 HUME. facts and authorities. It is remarkable, however, that he hesitated much as to the subject he should choose for his historical labours, and more strange still that he should have balanced between England and the Church. From this he was dissuaded chiefly by the strong recommendations of Adam Smith and Sir Gilbert Elliott. I have this fact upon the authority of Dr. Robertson, who, in relating it to the late Lord Meadowbank, added, "It would, at any rate, have suited me had he adhered to the plan he himself pro- posed, as the ' History of England ' would have thus been left open, which fell in with an early plan of my own." After the publication of his ' History' was closed in 1761, being now fifty years old, and possessed of an ample competency, Mr. Hume resolved, he tells us, " never more to set his foot out of his native country, enjoying the satisfaction of never having asked a favour, or made advances to any great man's acquaint- ance/' In less than two years, however, a great man's repeated solicitation to him changed his plan of life ; and he accompanied Lord Hertford, the British Ambassador, to Paris, with the immediate prospect of being appointed Secretary of Embassy. This was realized ; and in 1765, when the Ambas- sador went to Ireland as Lord Lieutenant, the phi- losopher was for part of the year charge d'affaires. His station, his agreeable manners, but above all his philosophical, including his irreligious, fame, were well suited to make a deep impression upon the society of the Paris circles. He was as popular among the wits, the philosophers, the coteries, and the women, HUME. 223 .as Franklin was at a later period, when his name was given to articles of fashionable attire. One of his let- ters gives an amusing account of the Dauphin, after- wards Louis XVI., then a child, having paid him court at his presentation, by speaking familiarly of his works, and of his younger brother, afterwards Louis XVIIL, having followed in the same complimentary strain. The charms, however, of such society as Paris then presented, the elegance of the manners, the easy good humour of the inhabitants, the freedom from all coarse dissipation, and, above all, from fac- tious brawls, naturally made a pleasing contrast with that which he had left behind him at home. There certainly was nothing in this country more alien to his nature, and less suited to his taste, than our poli- tical violence ; and the intolerance of our religious feelings, as well as the rudeness of our manners, he had some right to complain of, when a man like Dr. Johnson could be found to roar out " No, Sir !" in his presence, on being asked by a common friend to let him present the Historian to the Moralist. Upon a subsequent occasion the same intolerant believer be- haved with personal insolence and vulgar rudeness to Dr. Smith,* as good a Christian as himself, and a man of purer moral life, merely because he had, while afflicted with Mr. Hume's recent death, vented his grief in a touching panegyric upon his undoubtedly profound wisdom, and his virtue free from all re- * Mr. Smith came to a company, of which Professor Millar, the relater of the fact, was one, and seemed to be much disturbed. It turned out that Dr. Johnson had just said to him, before another company, with great rudeness, " You lie.'1 221 HUME. proach. This model of bigotry and rudeness had, notwithstanding, met at dinner, with perfect satisfac- tion, and conversed for hours, with Wilkes, whose life was as abandoned as his faith was scanty, who had been convicted of blasphemy and obscenity in a court of justice, and who held in bitter scorn every one of the sturdy moralist's religious and political principles. But Wilkes was English, Hume Scotch. From the country of the Johnsons, the latter deemed that he had made a happy escape, when he found himself among the gay, the polite, the tolerant French ; and he remained there happy, and respected, and beloved, till 1766, when he was diverted from his project of settling in Paris for the rest of his life, by being appointed Under-Secretary of State in General Con- way's ministry, who was Lord Hertford's brother. He held that office for about two years, and in 1769 returned to Edinburgh with an income of a thousand a-year, the produce of his own honest industry, " healthy," as he says, " but somewhat stricken in years, with the prospect before him of long enjoying his ease, and of seeing his reputation increase/' During the first few months of his residence at Paris he was not Private Secretary, as he tells one of his correspondents whom he chides for making that mistake, as will be seen in the Appendix ; and he adds that he performed all the duties of the Secretary of Embassy, Sir Charles Bunbury, who was the brother- in-law of Lord Holland and the Duke of Richmond, and who, being thus protected, did nothing beyond receiving the salary. Lord Hertford, however, ex- erted his influence to obtain Mr. Hume's appoint- HUME. 225 ment in the room of Sir Charles ; and Marshal Con way being Secretary for Foreign Affairs, he prevailed over Sir Charles's family interest. Mr. Hume was appointed 2d July, 1765 ; and, on Lord Hertford's immediately after being removed to Ireland as Lord-Lieutenant, he became Charge d'Affaires until the Duke of Richmond's arrival as Ambassador in the month of October. By Lord Aberdeen's kindness I have been allowed to examine the correspondence of the Embassy with Mar- shal Conway during these four months ; and it is highly creditable to the philosopher's business-like talents, and his capacity for affairs. The negotiations of which he had the sole conduct related to the impor- tant and interesting discussions of Canada ; matters arising out of the cession by the Peace of Paris ; and to the demolition of the works at Dunkirk, also stipulated by that treaty. His dispatches, some of them of great length, most of them in his own hand, are clearly and ably written. The course which he describes himself as pursuing with the very slippery and evasive minis- ters against whom he had to contend, particularly the Due de Praslin, appears to have been marked by firm- ness and temper, as well as by quickness and sagacity. His memorials, of which two or three are given, show a perfect familiarity with diplomatic modes and habits, and they are both well written and ably reasoned. His information must have been correct ; for he obtained a knowledge of the secret proceedings of the Assembly of Clergy, which, though convoked for the purpose of obtaining the usual don gratuit, chose to enter upon the discussion of all the clerical griev- ances, while they kept their deliberations carefully Q 226 HUME. secret, and were opposed by the Parliament of Paris as soon as their proceedings became known. Mr. Hume obtained a very early though somewhat exaggerated account of these things through two of the foreign ambassadors ; and when he communicated it to the Bishop of Senlis, he was treated with contempt, as if nothing could be so wild, and as if some enemy of the Church had invented the fable to discredit her. Mar- shal Con way appears by his dispatches (which are also excellent) to have rested his hopes of these differ- ences passing off on the prevailing irreligious spirit in France, where " the Dauphin alone," he says, " has any care for such matters ; and he has of late taken a mili- tary turn." In a short time the whole ferment was allayed by the prudent and able conduct of Brienne, Archbishop of Toulouse ; the don gratuit was voted ; and the Assembly was prorogued to the following May. Mr. Hume praises Brienne very highly on this, as indeed he did on all occasions. In John Home's Journal of his excursion with the historian to Bath, in his last illness (1776), we find the same opinion expressed ; Hume considering him as the only man in France fit to be minister, and relating several instances of his great ability.1* It was the same prelate, thus highly commended, who proved so insufficient to meet the tempest of the Revolution, when, twelve years later, he was placed in the situation for which the partiality of the historian had early predicted his exclusive fit- ness. -\ * Mackenzie's Life of John Home, p. 170. •f One writer has taken upon him to decide against Mr. Hume's HUME. 227 While Mr. Hume lived in Paris, he was applied to by some friends of Rousseau, who had become tired of his fantastic plans of solitude in Switzerland, and who was doubtful of his reception in French society, as others naturally were of his power to demean himself so as to make himself bearable in it ; and intending shortly to remove from France, and settle in England, he ex- pressed his readiness to take charge of the "interest- ing solitary," as he was called, whose writings he ad- mired in common with the rest of the world. He wrote to Rousseau, and offered to take him over to England ; the offer was immediately accepted, with the warmest expressions of gratitude. He came to Paris, on a permission of the Government to pass through France, notwithstanding the decree of arrest still in force against him. On his arrival, in December, 1765, he chose to parade himself daily in the neighbourhood of his hotel, in his ridiculous Armenian dress. The insolence of this proceeding in a person only by sufferance at large, made the police intimate that he must leave the coun- try ; and he accompanied Mr. Hume to London, at the beginning of January. He does not deny that he was talents for public business, certainly in perfect ignorance of the sub- ject. After saying that it would be superfluous to inquire in what manner he executed the duties of his office as Under Secretary, he adds, ll Certain it is that the state papers of those times evince no extraordinary marks of splendid abilities " (Ritchie's Life of Hume, p. 281) ; as if the Under Secretary of State had any con- nexion with these papers — or as if this writer had carefully exa- mined them, when he had just said the inquiry would be super- fluous ! But he who so discharged the similar — nay, the same duties of Ambassador, must have acted with equal ability as Foreign Under Secretary. Q2 228 HUME. treated with the utmost kindness, and that every thing was done which friendship could devise to render his stay in London and its neighbourhood agreeable. Mr. Hume then, finding that he was resolved to live at a distance from society, and had intended going into Wales, introduced him to Mr. Davenport,* who kindly offered him the use of his house at Wootton, in Derbyshire. The silly, misplaced pride of the poor man would not suffer him to accept this without pay- ing an equivalent ; and he was allowed to sit at an almost nominal rent of thirty pounds. He went to Wootton about the 20th of March, 1766. His letters to Mr. Hume, of the 22nd and 29th, are full of gratitude and affection, though he had seen three weeks before the supposed letter of Frederick II. ; for he speaks of it to his friend De Peyron, llth March; and he says, that on asking Hume if it was Horace Walpole's, "he neither said yes nor no," a silence afterwards made one of his charges against Hume. On the 5th of April he writes to Madame de Bouffiers, still full of gratitude to Mr. Hume, who, he says, had obtained for him the comfort and pleasure of his retreat in Derbyshire. Two days after, 7th April, he writes to a friend not named, and sends a contradiction of Frederick's letter to a newspaper : Rousseau's letter speaks of secret enemies, under the " mask of perfidious friendship, seeking to dishonour him ;" and on the 9th he writes his ac- cusation of Mr. Hume to Madame de Boufflers, so that it is clear he had all at once, between the 5th and 7th, * Grandfather of Lady Williams, wife of Mr. Justice Williams. HUME. 229 by exciting his warm and feverish imagination, sud- denly broke with his benefactor and " dear patron," as he before called him. His proofs of the conspiracy, and of Mr. Hume's secret enmity, are truly the workings of a sick brain, and sick with vanity ; as appears, among other symptoms, from his declaring how happy it made him to observe the popularity Hume had gained at Paris by his kindness to Rousseau ; and as also ap- pears, by his roundly asserting that his own popu- larity and following in England was extraordinary, until this plot was concocted to decry him. The let- ter is at the bottom of it all.* He at once pronounced that he knew it from its style to be D'Alembert's, and was enraged when told that it was certainly written by Horace Walpole — " as if," said he, " it were pos- sible I could mistake D'Alembert's style, and imagine an Englishman's French to be his." Then D'Alem- bert was a friend of Hume's ; and though D'Alembert had no more to do with the joke than Rousseau him- self, this was made the foundation of a quarrel ; for not only was D'Alembert Hume's friend, but a M. Tronchin was Hume's landlord, whose father had slandered Rousseau at Geneva ; and others of his ene- mies, real or supposed, turned out to be Hume's friends also. This was, he gravely asserts, a clear case of conspiracy made out against Hume, who must have in- veigled him over to England in order to ruin his repu- tation. One of the overt acts of this plot was the obtaining, through General Conway, a pension for him who was starving, of a hundred a-year. But it is to * See these letters in CEuv., vol. vii., p. 138, 139, 148 et seq. 230 HUME. be remarked, that the only part of the whole statement which he at once willingly disbelieved, although it was the only part that had a real foundation, was Hume's helping him to the pension. Therefore, having in the heroics of his first indignation thrown it up, he at once offered afterwards to take it back, and complained of the whole arrears not having been paid. Mr. Hume hearing that this frantic creature was writing constantly to Paris complaints of being de- ceived and persecuted by him, wrote to desire he would specify his grounds ; and then came a letter, full of the most ridiculous charges, ascribing to Mr. Hume's most indifferent acts, even to his looks, the most black de- signs; a letter plainly proving that the writer was deranged in one region of his mind, and that vanity was, if not the main cause of his malady, certainly the pivot on which it turned. No one can read that let- ter without a feeling of indignation ; for it shows throughout quite reason enough to make its writer answerable for his pure selfishness and his unbearable suspicions. It is a source, too, of irritation to the reader, that of the many persons whom he called in as arbi- trators, by sending them copies of his favourite pro- duction, not any one appears to have had the manly firmness, the true and rational friendship for Rousseau himself, of at once plainly declaring, what all of them must needs have felt when they read it, that the whole was a fiction of the man's own brain. Lord Marischal seems, indeed, to have perceived that any communication with such a creature was unsafe; and he let him know that henceforth they must no longer correspond. But for this notice, he no doubt HUME. 231 would have been the plotter of the next conspiracy ; for Rousseau had for some years desired to consider him as a father, and always addressed him, a steady old soldier and political intriguer, wholly void of any sentiment beyond those of heat and cold, hunger and thirst, by that endearing and ridiculous title. It is known that Rousseau, a year or two after his return to France, admitted that the foggy climate of England had produced in him a mental affection, and that he had been to blame in his quarrel with Hume ;* but he never had the common fairness and gratitude to address this confession to his benefactor, or to any of those whose ears he had sought to poison with his malignant slanders. Contrary to his invariable practice, when attacked for his writings, Mr. Hume very unadvisedly gave himself the trouble, and underwent the anxiety, of writing an answer to this silly and malignant indi- vidual. He published a short but detailed statement of all that had passed between them, This step he took contrary to the earnest advice of Adam Smith, whose letter remains, strongly dissuading him from taking any notice of Rousseau's slanders. He ap- pears to have been overpowered by D'Alembert and D'Holbach, who, living in the gossip and slander- loving credulity of Paris society, were afraid lest Rous- seau's constant letter -writing might produce an effect * See Bernardin de St. Pierre's statement of his conversation (L'Arcadie, Preambule), or Appendix aux Confessions, CEuv., vol.i., p. 642. The passage is given in the Life of Rousseau, which imme- diately precedes the present piece. 232 HUME. unfavourable to their friend. Certain it is, that Hume's publication, wholly superfluous to all men of ordinary sense and common candour, was insufficient to convince such ill-natured and silly people as the Deffands and their flatterers, who were anxious to have a pretext for levelling their malice at the Eng- lishman and the philosopher; and though despising Rousseau from the bottom of their hearts, were willing enough to make his fancied grievances a cloak for their attacks upon Mr. Hume. It seems plain that his own subsequent reflection upon the matter brought him over to Mr. Smith's opinion : for in the sketch which he has left of his own life, he makes not the least allusion to his quarrel with Rousseau, although, in his pam- phlet, he says that it gave him more trouble and annoy- ance than any thing that had ever happened to him. Mr. Hume returned to Edinburgh in 1766, but early next year he was appointed Under-Secretary of State under Marshal Conway, and held that office above a year. In 1769, some time after he resigned it, he returned to Edinburgh, and took a house in the only part of the new town then built, St. An- drew's Square. With the exception of a journey to Harrowgate for his health, and another to Bath the year he died, he lived in his native country during the remainder of his life, enjoying the constant society of his old friends ; and himself the delight of their circles by his abundant spirits, his never-failing good- humour, and even temper, and the kindness as well as the uprightness of his character. In the spring of 1775, he tells us, he was seized with a disease in his bowels. " At first," he says, " it gave me no HUME. 233 alarm, but has since, as I apprehend it, become mor- tal and incurable. I now," adds the philosopher, reckon on a speedy dissolution. I have suffered very little pain from my disorder, and what is more strange, have, notwithstanding the great decline of my person, never suffered a moment's abatement of my spirits ; insomuch that, were I to name the period of my life which I should most choose to pass over again, I might be tempted to point to this latter period. I possess the same ardour as ever in study, and the same gaiety in company, I consider, besides, that a man of sixty-five, by dying, cuts off only a few years of infirmities ; and though I see many symptoms of my literary reputation breaking out at last with additional lustre, I could have but few years to enjoy it. It is difficult to be more detached from life than I am at present." While he continued to decline by a gradual ex- haustion, he continued to see his friends about him as usual, and his gaiety was never clouded by the pros- pect before him now drawing to a close. A few weeks before his death, when there were dining with him two or three of his intimate companions, one of them, Dr. Smith, happening to complain of the world as spiteful and ill-natured, "No, no," said Mr. Hume, " here am I, who have written on all sorts of subjects calculated to excite hostility, moral, political, and religious, and yet I have no enemies ; except, indeed, all the Whigs, all the Tories, and all the Christians.'* When his strength gradually failed, he was un- able to remain so long as before in the company of his friends. By degrees he became confined to his 234 HUME. room the greater part of the day, and at last alto- gether. But his intellect and his calmness continued to the last. A letter to Madame de Bouftlers remains, written only five days before his death, and occasioned by the decease of the Prince de Conti, her great friend. " I am," he says, " certainly within a few weeks, and perhaps a few days, of my own death ; yet I cannot help being struck with the Prince's, as a great loss in every particular/' — "I see death," he adds, "approach- ing gradually, without anxiety or regret. I salute you with great affection and regard, for the last time." This was written on the 20th of August ; on the 25th he was no more. On that day he gently expired, with- out a struggle, in the sixty-fifth year of his age. He was buried in the cemetery on the Calton Hill, where a conspicuous monument is erected to his memory. He had shown a feverish anxiety for the publication of one work, his ' Dialogues on Natural Religion ;' and he left this with his other manuscripts to Dr. Smith ; but giving positive injunctions to publish this work, and allowing no discretion whatever upon the subject. Nay, he left a legacy of two hundred pounds, to be paid on the publication, though all the other legacies were made payable at the first term after his death : that is, Whitsuntide or Martinmas, according to the prevailing habit of the Scotch in their money arrangements. Smith refused to publish them ; and there exists a curious correspondence between him and Mr. Hume of Ninewells, the philosopher's brother, on the subject. Smith, about the same time, stopped a publication of all the ' Essays,' which included one on the * Immortality of the Soul,' and another, both be- HUME. 235 lieved to be spurious. The ' Dialogues' were so con- stantly corrected in his own hand, that they appear as if wholly re-written : a specimen of this is given in the Appendix. His nephew, afterwards Mr. Baron Hume, published them in 1779. Having spoken of his writings at large, it remains to add that, though respecting these men may form various opinions, and especially respecting his philosophical works, of his character as a man there never was, nor could there be, but one. His great capacity all admit ; his genius for metaphysical inquiries, those who most differ with him, even those who most lament the use to which he directed it, confess to have been of the highest order — at once bold, penetrating, original. His talents for political speculation were of as brilliant a description, and were so admirably and so usefully applied, that his works are as yet unrivalled in that most important department of practical science ; and he may justly be deemed the father of the liberal, enlightened, and rational system of national polity which has the general approval of statesmen, and would be everywhere adopted but for conflicting interests, and popular ignorance. But universal as is the assent to these positions, the judgment is no less unanimous which must be pro- nounced upon his character as a member of society, unless we reject all the testimony of all his contem- poraries, supported as it is by the tone and spirit of all his correspondence which has come down to us. He was a man of perfectly honest and single heart, of the kindest nature, of unequalled good-humour in the intercourse of society, carrying the same placid 236 HUME. disposition into those controversies which are most apt to ruffle or to sour the temper ; and even under disappointments which would have embittered the existence of most men, and disheartened almost all, neither losing his general good will towards others, nor suffering himself to be cast down. The party violence and delusions to which the failure of his ' History' was in part owing, he often has exposed, but certainly in no other terms than he would have used had his work succeeded : for he employed the same language in writing the portion first published at a time when he made sure of its success ; and he never afterwards troubled himself with doing more than uttering a good-humoured exclamation, or, per- haps, passing a joke at the expense of those who make themselves the tools of others by being the slaves to their own factious prejudices or propensities. But the re- ception of the < History' was not his only disappoint- ment, though it was the most severe. It would not be easy to find any instance of conduct more truly worthy of a philosopher than his bearing up against the repeated failures of the works he most esteemed, and the mortifying neglect which at first all his writings ex- perienced, with but one exception. He looked steadily forward, with a confidence truly surprising and amply justified by the event, to the time when, probably after his course was run, his fame would shine out with surpassing lustre. Even in his latter hours, when he had, in some measure, seen the failure of the injustice under which he originally suffered, he retained a confident belief that his renown had not yet nearly reached its highest pitch ; and that most admirable HUME. 237 • passage above cited from his 'Life,' written a few weeks before his death, makes a touching reference to the prospects which then cheered him, but which he knew were never, while he lived, to be realized. They were the only prospects, unhappily for him, which shed light around his dying couch ; yet such was the truly admirable temper of his mind, that no believer could possess his spirit in more tranquil peace, in con- templation of the end which he saw fast approaching, nor meet his last hour with more cheerful resignation. It is to be observed that the charges made against Mr. Hume for his sceptical writings, and for the irre- ligious doctrines which he published to the world, are in almost every respect ill-founded. He never had re- course to ribaldry, hardly ever invoked the aid even of wit to his argument. He had well examined the subject of his inquiries. He had, with some bias in favour of the singularity or the originality of the conclusions to which they led, been conducted thither by reasoning, and firmly believed all he wrote. It may be a question, whether his duty required him to make public the re- sults of his speculations, when these tended to unsettle established faith, and might destroy one system of belief without putting another in its place. Yet if we suppose him to have been sincerely convinced that men were living in error and in darkness, it is not very easy to deny even the duty of endeavouring to enlighten them, and to reclaim. But it is impossible to doubt that, with his opinions, even if justified in suppressing them, he never would have stood excused had he done anything to countenance and uphold what he firmly believed to be errors on the most important of all questions. Nor is 238 HUME. it less manifest that lie was justified in giving his own opinions to the world on those questions if he chose, provided he handled them with decorum, and with the respect due from all good citizens to the religious opi- nions of the State. There are but one or two passages in them all, chiefly in the ' Essay on Miracles,' which do not preserve the most unbroken gravity, and all the seriousness befitting the subject. In his familiar correspondence he was a little less precise, though even here he was very far from resem- bling the Voltaire school. In his conversation he seldom alluded to the subject, but occasionally his opinions were perceivable. Thus, when one of the University, the late Mr. John Bruce, professor of logic, asked him to revise the syllabus of his lectures, he went over the proof-sheets with him ; and on coming to the section entitled ' Proofs of the Exist- ence of the Deity/ Mr. Hume said, " Right ; very well." But the next section was entitled ' Proof of the Unity of the Deity/ and then he cried out, " Stop, John, stop : who told you whether there were ane or mair?" The same professor met him one day on the staircase of the College Library, where the in- scription " Christo et Musis has cedes sacrarunt ewes Edinenses" drew from the unbeliever an irreverent observation on the junction which the piety rather than the classical purity of the good town had made between the worship of the heathen and our own. That his conversation, however, was habitually free from all irreverent allusion, there can be no more complete proof than his uninterrupted intimacy with a man who never would have tolerated the least devia- HUME. 239 tion from perfect decorum in that particular, Dr. Ro- bertson. The reflection which naturally arises from their friendship is, first, that so venerable an authority has pronounced in favour of his friend's conduct ; that he never deemed his writings an offence against even the ecclesiastical laws of his country, much less against good morals ; that he regarded those speculations which he the least approved and the most lamented, as justi- fied by their author's honest sincerity of purpose ; and that he considered the conduct of his argument as liable to no reprobation even from himself, a sincere believer, a pious Christian, a leading Presbyter of a Church whose discipline is peculiarly strict, a man above almost all other men regardful of decorum in his own demeanour, professional and private. It is another reflection, suggested by the same fact, that such bigots as Dr. Johnson are exposed to our reprobation, almost to our contempt, for being unable to bear the presence of a man with whom Robertson deigned, and even loved, to associate. Assuredly the English lay- man had not a more pious disposition than the Scottish divine ; the historian of the Reformation had rendered as valuable service to the cause of religion as the essay- ist. The man who had passed his nights with Savage in the haunts of dissipation, and whom a dinner could tempt to sit for hours by Wilkes, might well submit to the society of a man through his whole life as pure in morals, as blameless in conduct, as those others were profligate, and abandoned. But Robertson's faith was founded on reason and inquiry, not built upon the blind devotion to established usages ; and his piety, while charity tempered it, was warmed at the genial 240 HUME. fire of a learned and inquiring philosophy, and pro- ceeded from his reason, not, like the dogmatical zeal of Johnson, inspired by fierce passions, matured by hypo- chondriacal temperament, stimulated by nervous fears. The one could give a reason for the faith that was in him — the other believed upon trust ; the one believed because he could argue — the other because he was afraid ; the one grounded his religion upon his learn- ing— the other upon his wishes and his temper. The intolerant layman seemed to betray in his demeanour his soreness, in his horror of discussion a lurking sus- picion that all was not sound in the groundwork of his system. The tolerant and philosophic divine showed a manly confidence in the solidity of the altar at which he ministered. While Johnson was enraged at the foundations of his ill-understood, unexamined belief being scrutinized for fear they should be shaken, Robert- son, who well comprehended on what his faith rested, defied the utmost inquiry and most active efforts of his adversaries, well assured that out of the conflict, how- ever fiercely sustained, the system to which he was at- tached, because he understood it, must come with new claims to universal acceptation. ( 241 ) APPENDIX. I HAVE been favoured with some unpublished letters of Mr. Hume by the kindness of my learned kinsman Lord Meadow- bank and other friends. By the following part of a letter to Dr. Clephane, we may perceive that he had once, at least, gone out of his line, and attempted something purely fanciful, apparently in verse. From the sample of his imaginative writing in the Essays, the e Epicurean' especially, little room is left for lament- ing that he did not further pursue this deviation from his ap- pointed walk. The letter is dated 18th February, 1751. His low estimate of Shakspeare breaks out in this letter ; but he became convinced in the sequel, that his kinsman's tragedy, 'Douglas,' to which he alludes, deserved the success which he justly predicts ; for we find him afterwards, to the same friend, giving his opinion, after reading the tragedy, and he terms it " a singular as well as fine performance, steering clear of the spirit of the English theatre, not devoid of Attic and French elegance." He seems to have formed a very low estimate of the English genius in those days ; for, speaking of Lord Ly ttelton's ' Henry III.,' which he hears is to be in three quarto volumes, he exclaims, " O magnum, horribile, et sacrum libellum ! — the last epithet probably applicable to it in more senses than one" — and adds, " however, it cannot well fail to be readable, which is a great deal for an English book now-a-days." "Ninewells, near Berwick, 18th February, 1751. ..." But since I am in the humour of displaying my wit, I must tell you that lately, at our idle hours, I wrote a sheet called the c Bellman's Petition,' wherein (if I be not partial, 242 HUME. which I certainly am) there was great pleasantry and satire. The printers in Edinburgh refused to print it (a good sign, you'll say, of my prudence and discretion). Mr. Mure, the member, has a copy of it : ask it of him if you meet with him, or bid the Colonel, who sees him every day in the house, ask it; and, if you like it, read it to the General, and then return it. I will not boast, for I have no manner of vanity. But when I think of the present dulness of London, I cannot forbear exclaiming, ( Rome n'est pas dans Rome : c'est par- tout oil je suis.' " A namesake of mine has wrote a tragedy, which he ex- pects to come on this winter. I have not seen it, but some people commend it much. It is very likely to meet with success, and not to deserve it ; for the author tells me he is a great admirer of Shakspeare, and never read Racine. (t If you answer this any time within the twelvemonth, it is sufficient ; and I promise not to answer your next at less than six months' interval. And so, as the Germans say, ' Je me recomante a fos craces.' " Yours, " DAVID HUME." The following, to the same correspondent, gives an account of his establishment after his election as librarian : — " Edinburgh, 5th February, 1752. " I must now set you an example and speak of myself; by this I mean that you are to speak to me of yourself. I shall exult and triumph to you a little that I have now at last, being turned of forty, to my honour,, to that of learning, and to that of the present age, arrived at the dignity of being a householder. About seven months ago I got a house of my own, and com- pleted a regular family, consisting of a head, viz. myself, and two inferior members, a maid and a cat. My sister has since joined me, and keeps me company. With frugality I can reach, I find, cleanliness, warmth, light, plenty, and content- ment. What would you have more ? Independence ? I have it in a supreme degree. Honour ? That is not altogether wanting. Grace ? That will come in time. A wife ? That HUME. 243 is none of the indispensable requisites of life. Books? That is one of them, and I have more than I can use. In short, I cannot find any blessing of consequence that I am not pos- sessed of in a greater or less degree ; and without any great effort of philosophy, I may be easy and satisfied. "As there is no happiness without occupation, I have begun a work which will employ me several years, and which yields me much satisfaction." The following is his letter introducing the future Chancellor, then a young man of twenty, going for the first time to London, which he visited before he was admitted an advocate in Scotland : — " DEAR DOCTOR, " Edinburgh, 6th March, 1753. (t This is delivered to you by my friend Mr. Wedder- burn, who makes a jaunt to London, partly with a view to study, partly to entertainment. I thought I could not do him a better office, nor more suitable to both these purposes, than to recommend him to the friendship and acquaintance of a man of learning and conversation. He is young ; * Mais dans les ames bien nees La vertu n'attend point le nombre des annees.' " It will be a great obligation both to him and me if you give him encouragement to see you frequently ; and after that, I doubt not but you will think that you owe me an obligation, ' Ha in giovanile corpo senile senno.' But I will say no more of him, lest my letter fall into the same fault which may be remarked in his behaviour and his conduct in life — the only fault which has been remarked in them — that of promising so much that it will be difficult for him to support it. You will allow that he must have been guilty of some error of this kind when I tell you, that the man with whose friendship and company I have thought myself very much favoured, and whom I recommend to you as a friend and a companion, is just twenty. et I am, dear Doctor, " Your affectionate friend and servant, " Dr. Clephane." " DAVID HUME. R 2 244 HUME. There is a long letter to Dr. Clephane anxiously desiring his opinion upon the true causes of his l History ' having so entirely failed, and indicating his own notion that this was owing to his freedom in treating religious and ecclesiastical subjects, but expressing his surprise that such a tone should not rather have recommended his book to the favour of one class and the hostility of another, than have made it sink into oblivion and neglect. In a letter to Colonel Edmonstone he treats the same disappointment in a more jocose manner, indicating what he conceives to be the taste of the public, and their fondness for worthless writings. " Edinburgh, 25th September, 1757. " I am engaged in writing a new volume of history from the beginning of Henry VII. till the accession of James I. It will probably be published in the winter after next. I believe I shall write no more history, but proceed directly to attack the Lord's Prayer, and the Ten Commandments, and the Single Catechism, and to recommend suicide and adultery, and persist until it shall please the Lord to take me to himself. " Yours ever, "D. H." To ANDREW MILLAR, the Bookseller. " 12th April, 1755. " The second volume of my ' History' I can easily find a way of conveying to you, when finished, and corrected, and fairly copied. Perhaps I may be in London myself about that time. I have always said to all my acquaintance, that if the first volume bore a little of a Tory aspect, the second would probably be as grateful to the opposite party. The two first princes of the House of Stuart were certainly more excusable than the two second. The constitution was in their time very ambiguous and undetermined, and their parliaments were in many respects refractory and obdurate. But Charles the Second knew that he had succeeded to a very limited monarchy. His Long Parliament was indulgent to him, and even consisted almost entirely of Royalists, yet he could not be quiet nor contented with a legal authority. I need not HUME. 245 mention the oppressions in Scotland, nor the absurd conduct of King James the Second: these are obvious and glaring points. Upon the whole, I wish the two volumes had been published together ; neither one party nor the other would in that case have had the least pretext for reproaching me with partiality. ' ' I shall give no further umbrage to the godly ; though I am far from thinking that my liberties on that head have been the real cause of checking the sale of the first volume : they might afford a pretence for decrying it to those -who were resolved, on other accounts, to lay hold of pretexts. " Pray tell Dr. Birch, if you have occasion to see him, that his story of the warrant for Lord Loudon's execution, though at first I thought it highly improbable, appears to me at present a great deal more likely. I find the same story in Scotstarvel's ' Staggering State,' which was published here a few months ago. The same story, coming from different channels, with- out any dependence on each other, bears a strong air of pro- bability. I have spoke to Duke Hamilton, who says I shall be very welcome to peruse all his papers. I shall take the first opportunity of going to the bottom of that affair ; and if I find any confirmation of the suspicion, will be sure to inform Dr. Birch. I own it is the strongest instance of any which history affords of King Charles's arbitrary principles. " I have made a trial of * Plutarch,' and find that I take pleasure in it, but cannot yet form so just a notion of the time and pains which it will require, as to tell you what sum of money I would think an equivalent. But I shall be sure to inform you as soon as I come to a resolution. The notes requisite will not be numerous, nor so many as in the former edition. I think so bulky a book ought to be swelled as little as possible, and nothing added but what is absolutely requi- site. The little trial I have made convinces me that the undertaking will require time. My manner of composing is slow, and I have great difficulty to satisfy myself." The conclusion of this letter is extremely interesting, as proving the truth of the assertion in the ' Life' respect- 246 HUME. ing his careful and deliberate manner of composing. This Appendix gives further proofs from the MS. of his Works. To ANDREW MILLAR. " Edinburgh, 22nd September, 1756. <( Mr. Strachan in a few days will have finished the printing this volume ; and I hope you will find leisure before the hurry of winter to peruse it, and to write me your remarks on it. I fancy you will publish about the middle of November. I must desire you to take the trouble of distributing a few copies to my friends in London, and of sending me a few copies here ; the whole will be fifteen copies. " Notwithstanding Mr. Mallet's impertinence in not answering my letter (for it deserves no better a name),, if you can engage him, from yourself, to mark, on the perusal, such slips of lan- guage as he thinks I have fallen into in this volume, it will be a great obligation to me : I mean that I shall lie under an obligation to you ; for I would not willingly owe any to him. " I am, dear Sir, te Your most humble Servant, " DAVID HUME." To ANDREW MILLAR. « DEAR SIR, 1758 or 1759. " I am very glad that Mr. Robertson is .entering on terms with you. It was, indeed, my advice to him, when he set out for London, that he should think of no other body ; and I ventured to assure him that he would find your way of dealing frank, and open, and generous. He read me part of his ' History ;' and I had an opportunity of reading another part of it in manuscript about a twelvemonth ago. Upon the whole, my expectations, both from what I saw, and from my knowledge of the author, are very much raised, and I consider it as a work of uncommon merit. I know that he has em- ployed himself with great diligence and care in collecting the facts. His style is lively and entertaining, and he judges with temper and candour. He is a man generally known and esteemed in this country ; and we look upon him very HUME. 247 deservedly as inferior to nobody in capacity and learning. Hamilton and Balfour have offered him a very unusual price, — no less than five hundred pounds for an edition of two thou- sand ; but I own that I should be better pleased to see him in your hands. I only inform you of the fact, that you may see .how high the general expectations are of Mr. Robertson's performance. It will have a quick sale in this country, from the character of the author ; and in England, from the merit of the work, as soon as it is known. " Some part of the subject is common with mine ; but as his work is a History of Scotland, mine of England, we do not interfere ; and it will rather be an amusement to the reader to compare our method of treating the same subject. I give you thanks, however, for your attention in asking my opinion." It is not without some reluctance that I add the following letter, because it is likely to give an unfavourable and also an unfair impression of the writer's principles. But let it be re- membered that he sincerely believed in the unhappy dogmas of infidelity, and consequently held the whole subject of reli- gious opinions cheap. To have done so in public would have been exceedingly blameable ; in private, it seemed to his mind a necessary consequence of his indifference or contempt, that he should fall into the lax morality of the ancients on this point, and give an exoterical conformity to what he eso- terically disbelieved. In my very clear opinion this course is wholly repugnant to sound morals ; and is to be reprobated, whether in the excess to which Mr. Hume carried it, or in the lesser degree to which such reasoners as Dr. Paley have adopted it. The suppression of such a letter would have ap- peared inconsistent with the plan of writing Mr. Hume's life" historically, and not merely composing a panegyric upon him. To COLONEL EDMONSTONE. " DEAR EDMONSTONE, Not dated, but supposed, 1764. " I was just projecting to write a long letter to you, and another to Mr. V., when your last obliging epistle came to 248 HUME. hand. I immediately put pen to paper to assure you that the report is entirely groundless, and that I have not lost, nor ever could have lost, a shilling by Fairholm's bankruptcy. Poor John Adams is very deeply engaged with him ; but I had a letter last post from Dr. Blair which informs me that he will yet be able to save fifteen or sixteen thousand pounds. I am glad to give you also this piece of intelligence. " What — do you know that Lord Bute is again all-powerful? — or rather that he was always so, but is now acknowledged for such by all the world ? Let this be a new motive for Mr. V. to adhere to the ecclesiastical profession, in which he may have so good a patron, for civil employments for men of letters can scarcely be found. All is occupied by men of business, or by Parliamentary interest. It is putting too great a respect on the vulgar, and on their superstitions, to pique oneself on sincerity with regard to them. Did ever one make it a point of honour to speak truth to children or madmen ? If the thing were worthy being treated gravely, I should tell him that the Pythian oracle, with the approbation of Xenophon, advised every one to worship the Gods vo/txo; 9roXews-. I wish it were still in my power to be a hypocrite in this parti- cular. The common duties of society usually require it; and the ecclesiastical profession only adds a little more to an innocent dissimulation, or rather simulation, without which it is impossible to pass through the world. Am I a liar because I order my servant to say I am not at home when I do not desire to see company ? " How could you imagine that I was under- secretary to Lord Hertford, or that I would ever be prevailed on to accept such a character ? I am not secretary at all, but do the busi- ness of secretary to the embassy without any character. Bun- ^>ury has the commission and appointment — a young man of three or four and twenty, somewhat vain and ignorant, whom Lord Hertford refused to accept of, as thinking he would be of no use to him. The King gave me a pension of 200/. a-year for life to engage me to attend his Lordship. My Lord is very impatient to have me secretary to the embassy, and writes very earnest letters to that purpose to the ministers — and among the rest to Lord Bute. He engaged me somewhat HUME. 249 against my will to write also to such of my friends as had credit with that favourite, Oswald, Elliot, Sir Harry Erskine, and John Hume of Douglas. The King has promised that my Lord Hertford shall soon be satisfied in this particular ; and yet I know not how, I suspect that some obstacle will yet in- terpose, though nothing can be more scandalous than for a man to enjoy the revenue of an office which is exercised by another.

The appointments of this office are above 1000Z. a- year, and the expense attending it nothing ; and it leads to all the great employments.

" I am, dear Edmonstone, " Yours sincerely, " DAVID HUME." The following fac-simile extracts from the MS. of the ' His- tory' prove two things : — First, that Hume carefully composed and diligently corrected his composition; but secondly, that the finer passages having more occupied his attention, he had, before committing them to paper, more attentively elaborated and more nearly finished them. The characters of Alfred and of Edward III. are of this description, so is the earlier part of the magnificent description of the E-omish Interdict's operation. The MS. of the ' Dialogues ' affords an example of his repeated correction in his more ordinary passages. In the second edition of his works he again and again corrected ; and even his familiar letters appear to have been laboured with similar care : — merit in private " The personal bo" character of this Prince, both personal life, & public A may with advantage be set in opposition to that whioh that of any Monarch or citizen, which the Annals 250 HUME. of any age or any Nation, can present to us.

It is necessary to correct a very gross misstatement into which some idle or ill-intentioned person has betrayed an in- genious and learned critic respecting the papers of Mr. Hume still remaining and in Edinburgh. " Those who have exa- mined the Hume papers, which we know only from report, speak highly of their interest, but add that they furnish pain- ful disclosures concerning the opinions then prevailing among the clergy of the northern metropolis ; distinguished ministers of the Gospel encouraging the scoffs of their familiar friend, the author of the ' Essay on Miracles/ and echoing the blas- phemies of their associate the author of the * Essay on Sui- cide.' " These Edinburgh clergymen are then called " be- HUME. 255 trayers of their Lord," and much more is added of a like kind.* Now this heavy charge against some of the most pious and most virtuous men who ever adorned any church, Dr. Robert- son, Dr. Blair, Dr. Jardine, Dr. Drysdale, and others, seemed eminently unlikely to be well founded. I have caused minute search to be made ; and on fully examining all that collection, the result is to give the most unqualified and peremptory contradiction to this scandalous report. It is in- conceivable how such a rumour should have arisen in any quarter. A severe, and we may well be permitted to add, a singularly absurd observation of Archbishop Magee is cited in the same criticism. f His Grace describes Hume's heterodox writings as 1 ' standing memorials of a heart as wicked and a head as weak as ever pretended to the character of philosopher and moralist." Now I have no right to complain of the Most Reverend Prelate for forming so low an estimate of Mr. Hume's under- standing, and entertaining so bad an opinion of his heart ; an estimate and an opinion not confined by his Grace to one class of his writings, though undeserved by any. Yet it does appear somewhat strange that merely because one of the most able men that ever lived, and one of the most virtuous, unhappily entertained religious opinions very different from those of the Archbishop, therefore he must be proclaimed both a dunce and a knave. It may also be permitted us to wish that the disciples of the religion in which " the greatest of these things is charity," and in which erring mortals are forbidden " to judge lest they be judged," should emulate the candour and the charity of unbelievers ; for assuredly if Mr. Hume had lived to read the Archbishop's work on the 'Atonement/ though he might not have been converted by it, he would freely have confessed the great talents and the unspotted virtue of its author. * Quarterly Review, vol. Ixxiii. p. 556. f ^*> (256) ROBERTSON. JOINED in friendship and in fame with the great man whose life and writings we have been contem- plating, and, equally with him, founder of the repu- tation of our country for excellence in historical com- position, was William Robertson, also a native of Scotland. His father, a learned, pious, and eloquent divine, was settled for several years as minister of the Scotch church in London Wall, but had returned to Scotland before his marriage with Miss Pitcairn of Dreghorn, in the county of Edinburgh, and was settled at Borthwick, in the same county, at the time of the historian's birth, on the 19th of September, 1721. I have been curious to ascertain the kind of genius which distinguished his father beside his talent for drawing, of which I possess a specimen showing some skill,* and by the kindness of a kinsman I have had the great * It is a miniature in Indian ink of James, Earl of Seafield, one of the forfeited Lords, to whom he was believed to be distantly re- lated. A tradition prevailed in the family that they descended from John Knox. The historian professed himself quite unac- quainted with the reasons of this rumour which connected him with " the rustic Apostle," whose character and conduct he has described most faithfully and strikingly. ROBERTSON. 257 satisfaction of receiving a copy of the only sermon which he ever published, as well as of two or three hymns, translations, and paraphrases from the Hebrew of the Old Testament. The sermon is able, judicious, cor- rectly composed, both for accuracy of diction and se- verity of taste, and contains passages of great beauty and effect. It resembles what in England would be called an Ordination Sermon or Charge, being delivered at the opening of the Metropolitan Synod in May, 1737, and is a full description of the duties of ministers, the title of it being that " they should please God rather than men." The poetry is elegant and classical. Both productions plainly show that good taste, as well as strong but sober reason, came to the great historian by descent as well as by study. But that his father held opinions more strict on some subjects than the relaxed rigour of the Presbyterian rule prescribed half a century later, may be seen from his requiring his son's promise never to enter a play-house. This was stated by him in reference to his father, when debating the question of John Home's having written the play of ' Douglas/ It is needless to add that, however much he differed with his father on this subject, he strictly adhered through life to the promise thus given, insomuch that when Garrick and Henderson at dif- ferent times visited him, they entertained and interested him by exhibiting to him in private specimens of the art in which both so eminently excelled. The tra- ditional character of the venerable person whom I have mentioned, in his family, was anything rather than sour or stern, how severe and unbending soever may have been his moral feelings. For the sweetness s 258 ROBERTSON. of his placid temper, and the cheerfulness of his kindly disposition, I have heard him spoken of in terms of the warmest enthusiasm by such of his children as were old enough at the time of his decease to recollect him distinctly. The idea of again meeting him in another state was ever present to my grandmother's mind, (who was his eldest daughter,) and especially when stricken with any illness. It was with her a common source of argument for a future state, as proved by the light of nature, and in her pious mind a confirmation of the truth of Christianity, that, believ- ing in the Divine goodness, she could not conceive the extinction of so much angelical purity as adorned her parent, and so fine an understanding as he pos- sessed. Their mother was a woman of great ability and force of character ; but like many of that cast, women especially, she was more stern, and even severe, than amiable ; and this contrast, unfavourable to the one, redounded to the augmented love of the other. It cannot be doubted that the son's character derived a strong tincture from both parents, but that while he was mild and gentle in his temper, and of an engaging demeanour, his firmness and decision, nay, his inclina- tion towards the Stoical system of morals, and even to a certain degree of Stoical feeling too, was derived from his mother. The death of these two excellent persons was singu- larly melancholy, and served to impress on the minds of their family a mournful recollection of their virtues. Mr. Robertson had been removed to the Old Grey Friars Church of Edinburgh in 1733 ; and ten years after- wards, both he and his wife, seized with putrid fever, ROBERTSON. 259 died within a few days of one another, leaving eight children, six daughters and two sons, of whom Wil- liam was the elder. He had been educated first at the school of Dalkeith, under a very able teacher of the name of Leslie, a gentleman at that time of the great- est eminence in his profession. On his father's removal to Edinburgh, he was taken thither and placed at the University, though only twelve years old. His dili- gence in study was unremitting, and he pursued his education at the different classes for eight years with indefatigable zeal. He had laid down for himself a strict plan of reading ; and of the notes which he took there remain a number of books, beginning when he was only fourteen, all bearing the sentence as a motto which so characterised his love of learning, indi- cating that he delighted in it abstractedly, and for its own sake, without regarding the uses to which it might be turned — " Vita sine litteris mors." I give this gloss upon the motto or text advisedly. His whole life was spent in study. I well remember his constant habit of quitting the drawing-room both after dinner and again after tea, and remaining shut up in his library. The period of time when I saw this was after the ' History of America' had been published, and before Major Ren- nell's map and memoir appeared, which he tells us first suggested the ' Disquisition on Ancient India/ Consequently, for above ten years he was in the course of constant study, engaged in extending his inform- ation, examining and revolving the facts of history, contemplating ethical and theological truths, amus- ing his fancy with the strains of Greek and Roman poetry, or warming it at the fire of ancient eloquence 260 ROBERTSON. so congenial to his mind, at once argumentative and rhetorical ; and all this study produced not one written line, though thus unremittingly carried on. The same may be said of the ten years he passed in constant study from 1743, the beginning of his residence in a small parish, of very little clerical duty, to 1752, when we know from his letter to Lord Hailes he began his first work. But, indeed, the composition of his three great works, spread over a period of nearly thirty years, clearly evinces that during this long time his studies must have been much more subservient to his own grati- fication than to the preparation of his writings, which never could have required one half that number of years for their completion. Translations from the classics, and especially from the Greek, of which he was a perfect master, formed a considerable part of his labour. He considered this exercise as well calculated to give an accurate know- ledge of our own language, by obliging us to weigh the shades of difference between words or phrases, and to find the expression, whether by the selection of the terms or the turning of the idiom, which is required for a given meaning ; whereas, when composing origi- nally, the idea may be varied in order to suit the dic- tion which most easily presents itself, of which the influence produced manifestly by rhymes, in moulding the sense as well as suggesting it, affords a striking and familiar example.* His translationshowever, were not wholly confined to their purpose of teaching composi- * I may mention that both he and his son, the Judge, prescribed this exercise to me, and, among others, made me translate all the 4 History ' of Floras. ROBERTSON. 261 tion ; he appears to have at the same time indus- triously completed the work of rendering some ancient treatises, which peculiarly interested him. He had even prepared for the press a translation of Antoninus's ' Me- ditations/* having thus early felt a strong leaning towards the Stoical philosophy. The appearance of a very poor translation at Glasgow prevented the execu- tion of this design, but the work remains : I have it now in my possession, and shall give one or two pas- sages in the Appendix. In elocution he acquired faci- lity and correctness by attending a society which met weekly to debate literary and philosophical questions. This society gave rise many years later to another, which was frequented by the men who in after life proved the most distinguished of their countrymen : Hume, Smith (neither of whom ever took part in de- bate), Wedderburn (afterwards Chancellor), Fergu- son, Home (Lord Kames), were of the number. But his thirst of knowledge was not confined to these its more easy and more inviting walks. He had deeply studied some branches of the severer sciences. It is not, therefore, without good cause that he speaks of mathematical subjects (in his preface to the work on India) as having been embraced in his course of study, though not having been carried so far as a discussion of the Brahminical astronomy might require. In 1741, according to the constitution of the Scotch Church, he was licensed by the Presbytery of Edin- burgh to preach ; orders being only conferred upon a * Marc. Aurel. : 1W EIQ iavrov. 262 ROBERTSON. presentation to a living or Kirk. Two years after, he was appointed minister of Gladsmuir, a country parish in East Lothian ; and this event happened fortunately on the eve of the irreparable loss sustained by the family in the death of both their parents, which left his brother and his sisters wholly without provision. He immediately took the care of them upon himself, and would form no connexion in marriage until he had seen O them placed in situations of independence. He thus remained single for eight years, during which his eldest and favourite sister superintended his family. In her sound judgment he always placed the greatest con- fidence ; for he knew that to great beauty she added a calm and a firm temper, inherited from their mother, but with greater sweetness of disposition. An instance of her fortitude and presence of mind was sometimes mentioned by him, though never alluded to by herself, that a swarm of bees having settled on her head and shoulders while sitting in the garden, she remained motionless until they took wing, thus saving her life, which was in imminent jeopardy. She was married in 1750, and the year after he married his cousin, Miss Nesbit. While at Gladsmuir, where he remained fifteen years, his life was passed in constant study, and in the duties of his sacred profession. He rose very early, and devoted the whole morning to his books. Later in the day he had ample time for visiting the sick and the poor generally ; and he gave great attention to the important duty of examining and catechising the young people under his care. But nothing can be more absurd than the statement in some of the lives which ROBERTSON. 263 have been published, as if his whole time after break- fast was devoted to these duties. It would have been utterly impossible to find subjects for his visits in that small country parish, not containing two hundred families. It is remarkable that, with all the love of study which formed so striking a feature of his character, nay, with the contemplative disposition which his thirst of knowledge for its own sake plainly indicates, he should have joined an extraordinary fitness for the less speculative pursuits of active life, and a manifest willingness to bear a part in them. The rebellion of 1745 afforded an occasion on which he conceived that the dangers surrounding civil and religious liberty called for the exertions of all good citizens in its defence. On the news of the rebels marching towards Edinburgh he quitted his parsonage (manse) and joined the volunteers of the capital. How far they marched is not known ; but that they must have proceeded towards the Highlands, and for some time remained under arms, is certain from this, that he always men- tioned the effect of the first coal fire on his head after he had been for some time accustomed to burn peat only. When Edinburgh was surrendered he joined a small body of persons from the city, who offered their services at Haddington to the Commander-in-Chief. Soon after his marriage he was returned as a member to the General Assembly, and again his capacity and his inclination for active life , appeared. He devoted himself assiduously to the business of that body ; and, having a very strong and clear opinion in favour of lay patronage, the great question which divided the Church 264 ROBERTSON. of Scotland in that day, as, in truth, it again does in our own, he assumed the lead of its advocates. At first they formed a small minority of the Assembly ; but, by degrees, reason enforced by eloquence had its course, and he gained ultimately a complete victory over his adversaries. The persecution of John Home, by the fanatical party, for writing the moral and innocent and even pious tragedy of ' Douglas/ gave another occasion to show Dr. Robertson's liberal and rational sentiments. Such of the clergy as had attended the theatre to witness the representation were involved in the same bigoted outcry. Home himself bent to the storm, and resigned his living ; Robertson's judicious but spirited defence saved the rest from more than a rebuke to some, and a few weeks' suspension to others. He man- fully explained why he had never attended himself, say- ing, that it was only owing to the promise already men- ' tioned ; but he avowed that he saw no harm in the at- tendance of his brethren whom no such promise bound. He was now looked up to as the acknowledged leader of the moderate party ; and, as they soon after became the ruling body in the Church, he must be considered as the leading minister of that venerable body during all the time he continued in the Assembly. Of the lustre with which his talents now shone forth all men are agreed in giving the same account. I have frequently conversed with those who could well re- member his conduct as a great party chief, and their uniform observation was upon the manifest capacity which he displayed for affairs. " That he was not in his right place when only a clerical leader or a literary ROBERTSON. 265 man, but was plainly designed by nature, as well as formed by study, for a great practical statesman and orator," is the remark which seems to have struck all who observed his course. His eloquence was bold and masculine ; his diction, which flowed with perfect ease, resembled that of his writings, but of course became suited to the exigencies of extemporaneous speech. He had the happy faculty of conveying an argument in a statement, and would more than half answer his adversary by describing his propositions and his reason- ings. He showed the greatest presence of mind in debate ; and, as nothing could ruffle the calmness of his temper, it was quite impossible to find him getting into a difficulty, or to take him at a disadvantage. He knew precisely the proper time of coming forward to debate, and the time when, repairing other men's errors, supplying their deficiencies, and repelling the adverse assaults, he could make sure of most advantageously influencing the result of the conflict, to which he ever steadily looked, and not to display. If his habitual command of temper averted anger and made him loved, his undeviating dignity both of demeanour and of con- duct secured him respect. The purity of his blameless life, and the rigid decorum of his manners, made all personal attacks upon him hopeless ; and, in the management of party concerns, he was so far above any thing like manoeuvre or stratagem, that he achieved the triumph so rare, and for a party chief so hard to win, of making his influence seem always to rest on reason and principle, and his success in carrying his measures to arise from their wisdom, and not from his own power. They relate one instance of his being thrown some- 266 ROBERTSON. what off his guard, and showing a feeling of great displeasure, if not of anger, in a severe remark upon a young member. But the provocation was wholly out of the ordinary course of things, and it might well have excused, nay, called for, a much more unsparing visitation than his remark, which really poured oil into the wound it made. Mr. Cullen, afterwards Lord Cullen, was celebrated for his unrivalled talent of mimicry, and Dr. Robertson, who was one of his favourite subjects, had left the Assembly to dine, meaning to return. As the aisle of the old church, consecrated to the Assembly meetings, was at that late hour extremely dark, the artist took his opportunity of rising in the Principal's place and delivering a short speech in his character, an evolution which he accom- plished without detection. The true chief returned soon after ; and, at the proper time for his interposition, rose to address the house. The venerable Assembly was convulsed with laughter, for he seemed to be repeating what he had said before, so happy had the imitation been. He was astonished and vexed when some one explained the mystery — opened as it were the dark passage where Mr. Cullen had been acting. He said he saw how it was, and hoped that a gentleman who could well speak in his own person would at length begin to act the character which properly belonged to him.* That great additional weight accrued to him as ruler * A somewhat similar scene occurred in the House of Commons on the publication of Mr. Tickell's celebrated jeu d'esprit, ' Anti- cipation/ It only appeared on the morning of the day when the session opened, and some of the speakers who had not read it verified it, to the no small amusement of those who had. BOBEETSON. 267 of the Church, from the lustre of his literary fame, cannot be doubted ; and that the circumstance of his connexion with the University always securing him a seat in the Assembly, while others went out in rotation, tended greatly to consolidate his influence, is equally clear. But these accidents, as they are with respect to the General Assembly, would have availed him little, had not his intrinsic qualities as a great practical statesman secured his power. He may be said to have directed the ecclesiastical affairs of Scotland for more than a quarter of a century with unexampled success, and without any compromise of his own opinions, or modification of his views of church policy ; and he quitted the scene of his brilliant career while in the full vigour of his faculties, and the untarnished lustre of his fame. At the latter end of George II/s reign, that Prince, or his advisers, deemed it expedient to make a proposal, having for its object the elevation of this eminent person to a high rank in the English Church. The particulars are not known ; but Mr. Stewart, who probably had some intimation of them, says that the offer was met with " a rejection, in terms which effectually prevented a repetition of the attempt." Probably he considered it as, in substance, an insult to his character for sincerity as well as independence ; for though no man was less tainted by narrow-minded bigotry, and none probably could regard less than he did the differences, rather political than religious, which separate the two churches as matters of con- science, he yet had declared his aversion to Episcopacy on grounds not to be shaken, at any rate not to be shaken by a proposal accompanied with temporal 268 ROBERTSON. advantage, and lie would have deemed his entertaining it for an instant a corrupt sacrifice of his principles to the gratification of his ambition. While the conflict was raging in the Church Courts on Patronage, he had given to theworld his first pub- lished works — his historical articles contributed to a periodical work established by Smith, Wedderburn (afterwards Chancellor), Jardine, Blair, Russell, and others, under the name, since become more famous, of the Edinburgh Review, and a sermon preached before the Society for promoting Christian Knowledge, in January 1755. The Review contained many able and learned papers, and reached a second number, when its con- ductors were obliged to give it up, in consequence of the fanatical outcry raised against a most justly severe criticism upon a wretched production of theolo- gical bigotry and intolerance which had just disgraced the extreme party in the Church.* The subject of the sermon is one peculiarly suited to his habits of inquiry — the situation of the world at the time of our Saviour's appearance as connected with the success of his mission. The merits of this piece, as a sermon, are very great ; and it is admirable, as an historical composition, in that department which Voltaire first extended to all the records of past times. It was * This criticism was from the elegant pen of Dr. Jardine, one of the most pious ministers of the Church, and a very intimate friend of the Principal. The papers of the latter appear to have been chiefly written on subjects which he had occasion to consider as incidental to his historical researches, and he does not seem to have put forth his strength in their composition. They are slight as compared with Adam Smith's review of Johnson's Dictionary, and his excellent letter to the editors on the General State of Literature, recommending an en- largement of their plan, which was confined to Scottish publications. ROBERTSON. 269 written and published before the appearance of the 1 Essai sur les Moeurs ;' though, as has been already said,* detached portions of that work had appeared in a Paris periodical work. As a preacher he was most successful. His lan- guage, of course, was pure, his composition graceful, his reasoning cogent, his manner impressive. He spoke according to the custom of the Scottish Church, hav- ing only notes to assist his memory. His notions of usefulness, and his wish to avoid the fanaticism of the High Church party (what with us would be called the Low Church, or Evangelical), led him generally to prefer moral to theological or Gospel subjects. Yet he mingled also three themes essential to the duties of a Christian pastor. He loved to dwell on the goodness of the Deity, as shown forth not only in the monu- ments of creation, but the work of love in the redemp- tion of mankind. He delighted to expatiate on the fate of man in a future state of being, and to contrast the darkness of the views which the wisest of the heathen had, with the perfect light of the new dispensation. He oftentimes would expound the Scriptures, taking, as is the usage of the Kirk, a portion of some chapter for the subject of what is called lecture as contradis- tinguished from sermon ; and in these discourses, the richness of his learning, the remarkable clearness of his explanation, the felicity of his illustration, shone forth, as well as the cogency and elegance of his practical application to our duties in life, the end and aim of all his teaching. I have heard him repeatedly, occupying as he did from 1759 to his death the pulpit of the Old * Life of Voltaire. 270 ROBERTSON. Grey Friars, where his father had been minister before him. But one sermon, though I was very young at the time, I never can forget. The occasion was the celeb ra- tion (5th November, 1T88) of the centenary of the Revo- lution, and his sister, considering that to have heard such a man discourse on such a subject was a thing to be remembered by any one through life ever after, took me to hear him. It was of singular and striking inte- rest, for the extreme earnestness, the youthful fervour with which it was delivered. But it was in some pas- sages upon a revolution which he expected and saw approaching, if not begun, as well as upon the one which was long past, and almost faded from the memory in the more absorbing interest of present affairs, I well remember his referring to the events now going on on the Continent, as the forerunners of far greater ones which he saw casting their shadows before. He certainly had no apprehensions of mischief, but he was full of hope for the future, and his exult- ation was boundless in contemplating the deliverance of " so many millions of so great a nation from the fetters of arbitrary government." His sister and I often afterwards reflected on this extraordinary dis- course with wonder, and I feel almost certain of some such expressions as these having been used, and of his foretelling that our neighbours would one day have to celebrate such an event as had now called us together. We dined with him the same day on leaving the church, for it was the afternoon service that he had performed. His eldest son, afterwards Lord Robert- son, was of the company ; and when the Principal expressed his satisfaction at having had his presence at church (a thing by no means of weekly occurrence), ROBERTSON. 271 the answer was, " Aye, sir, if you'll always give us such, sermons, you may make it worth our while." " Ah," answered he, "you would like it, as the boys say," referring to a vulgar school taunt. I have again and again asked my learned kinsman to show me the ser- mon, which he admitted he possessed among his father's papers, fairly written out. His answer was that he wished to avoid giving it publicity, because, in the violence of the times, the author of it would be set down for a Jacobin, how innocent soever he was at the day of its being preached. Those times have hap- pily long since passed away. I cannot believe that any one has ventured to destroy this remarkable produc- tion, though hitherto it has not been found.* — I return to the course of his life. From 1752 to 1758 he had been diligently occu- pied with the ' History of Scotland ;' in 1759 it ap- peared. The success of this admirable work was as immediate and as universal as it was deserved. The whole edition, though of two quarto volumes, was ex- hausted in less than a month. There was but one voice in every part of the country, and among all ranks and descriptions of men, both upon its pure and beautiful composition, its interesting narrative, and its anxious and conscientious accuracy. A murmur was heard from the Jacobite party, who in Scotland * My kinsman, executor of Lord Robertson, has at length, after many a fruitless search, succeeded in finding the sermon, and it now lies before me, written in his own hand. I can see the places where he added remarks made on the inspiration of the moment, particularly the one above cited, of which I am the more certain from the subsequent conversations of his sister, who heard it with me. 272 ROBERTSON. were more wild and romantic, and more unreasoning, than in the southern parts of the island. Not satis- fied with the far less harsh view of Mary's conduct which he had taken compared with Hume's, partial as Hume was to the Stuarts, it was the fashion of this little set of enthusiasts to say that he had " cut her with a razor dipped in oil." It was no little conces- sion to have acquitted her of all part in Babington's conspiracy, to have left her share in Darnley's murder hanging in doubt, to have pronounced a decisive judg- ment against Elizabeth, for her whole conduct both towards the Scots and their Queen. These silly per- sons would not be appeased unless, in the face of all her own conduct and her own words, she was ac- quitted of the outrage on common decency of wed- ding her husband's murderer, and screening his accom- plices from punishment. But the clamour, though it produced a book or two in support of this most des- perate cause, spread very little even in Scotland ; and the national vanity was inexpressibly gratified by this great triumph in the most important and most popu- lar of all the walks of polite learning. The delight of his friends was of course still more lively. Aware of his merits, as they always had been, and somewhat impatient of the length of time which he had suffered his known capacity to remain barren, now that they saw the abundant fruits crowning his works, they exulted as if they gathered in the rich harvest in common, and confessed that the postponement had not stunted the growth, but, like a fallow, made it more plenteous and more rich. Ill truth, the discipline of so many years' study to which he had subjected him- self, the long delay which he had interposed, though ROBERTSON. 273 all the while thoroughly versed in all the arts of com- position, had the salutary effect of making his first work as mature as his latest production. This is per- haps a singular instance of one who had from his early youth been studying diction, who had been constantly writing, and had for long years been almost as expert as he ever became, withholding himself from employing the faculty which he had acquired, except to render himself still more dexterous in its use, and continuing four and twenty years ere he appeared before the world, nay, eighteen years before he even began to write the work which should lay the foundation of his fame. He was eight and thirty when he published it. But then it is another singularity as great, that considerable doubt remains if any of his subsequent works surpassed this first pro- duction. Among his exulting friends, David Hume deserve to be singled out for the heartiness of his disinterested joy. Far from not bearing a brother near the throne, he entirely rejoiced in his rival's success, and even in the uniting of all testimonies to his merits, so strongly contrasted with the universal clamour for some years raised against his own 'History/ and the niggard praise which, even after five years, that work received. Among other kind acts, he encouraged some literary men at Paris to translate the new l His- tory ;' and he thus jocosely touches upon the loss of his undivided superiority as an historian : " I warn you, however, this is the last time I shall ever speak the least good of it. A plague take you ! Here I sat T 274 ROBERTSON. near the historical summit of Parnassus, immediately under Dr. Smollett,* and you have the impudence to squeeze yourself past me, and place yourself directly un- der his feet! Do you imagine that this can be agree- able to me ? and must not I be guilty of great simpli- city to contribute by my endeavours to your thrusting me out of my place both at Paris and in London ? But I give you warning that you will find the matter somewhat difficult, at least in the former city. A friend of mine who is there, writes home to his father the strangest accounts of that kind, which my modesty will not allow me to repeat, but which it allowed me very deliciously to swallow." Just before the ' History ' was published, the author visited London for the first time ; and his merit hav- ing been made known to some persons of eminence and of good taste, who had been allowed to peruse por- tions, at least, of the proof sheets, his reception was of a distinguished kind. I have now before me some letters of his to his bosom friend, and steady coadjutor in ecclesiastical politics, Dr. Jardine, and it is pleasing to mark the natural expression of his satisfaction with his visit. The first letter which I shall give begins with a good deal of narrative upon the success of John Home's c Agis/ At that time the violence and folly of the fanatical party made the subject of this elegant and amiable writer's dramas doubly interesting to his friends. The tragedy, so successful at first, chiefly be- * He of course had the lowest opinion of this writer's parts as an historian. ROBERTSON. 275 cause of its predecessor, ' Douglas,'* having succeeded through merit, and partly because of high patronage, is a very middling performance, and, like all Mr. Home's plays, except ' Douglas,' has long since sunk into deserved oblivion. Dr. Robertson's amiable zeal for his friend, and his exultation at the success of his piece, is very striking in this letter. " MY DEAR SlB, " Thursday, March 16th. " When I wrote you the history of ' Agis,' I certainly foresaw some of the purposes for which it would serve, and that you would naturally employ it for an use of mortification to the wicked, as well as of comfort to the pious. I could not, however, have any presage either of the absurdity of the players, or of the malice and credulity of Home's enemies, which rendered my account doubly seasonable. I now put it in your power to mortify them with still fuller accounts of the triumphs of ' Agis.' Never were there more crowded houses than during the whole run of the play. The Prince of Wales was present no less than three different nights, one of which a benefit night. Such honourable distinction was never formerly bestowed upon any new piece. The snarlers and small critics are somewhat enraged at this, and every one against Lord Bute ; though I can assure you, the frequency of the Prince's attendance was his own proper motion, and pro- ceeded from his admiration of ' Agis.' But what is still more honourable for Home, since the ninth night, ' Agis' has been acted twice, and both times the house was more crowded (if possible), and the applause louder than ever. There has ap- * * Douglas' was the second in date of composition, though the first performed. Garrick had rejected it peremptorily; and it was brought out with great success at Edinburgh. Garrick had also rejected all Home's other pieces ; until Lord Bute and other persons of distinction patronised the poet, when the manager, following his ignoble nature, suddenly became the zealous and forward patron of all he wrote, and joined those noble supporters in fencing the very poor tragedy of < Agis' on the public. T 2 '276 ROBERTSON, peared a critic on 'Agis,' one Henerden. I am persuaded Home has hired him, and given him a crown to write such execrable stuff. Every body laughs at it ; and, in the wicked language of this town, it is called a d d tame piece of non- sense. Wedderburn makes all the progress we could wish : even the door-keeper of the House of Peers tells me that ' he is a d d clever fellow, and speaks devilish good English.' This very morning he was retained in a Plantation cause before the Privy Council, which is a thing altogether extra- ordinary for so young a man. You cannot imagine what odd fellows his rivals are, and how far and how fast he is likely to go. " I can't say so much about my own progress. I unluckily have but one copy of my ' History/ otherwise I might advance with more rapidity. I have been with Horace Walpole, a son of Sir Robert's, a very clever man, and of great leading among the literary people of fashion. We had much conversation about Mary. He is one of the greatest critics I ever met with, as to the facts in the period. Our notions jumped perfectly. Part of my papers are in his hands ; the Duke of Argyle has another ; Scott, who was preceptor to the Prince of Wales, a third ; and Lord Royston a fourth. I have got from this last a vast collection of original papers ; many of them are curious. I am advised by several people to transcribe as many as will swell the book to a guinea price. The taste of this town is such, that such an addition will be esteemed very meritorious ; and though it cost me little but having an amanuensis, it will add to the price in proportion to the increase of bulk. You see I begin to learn the craft of authorship. I have hitherto industriously avoided meeting with booksellers, but shall soon begin my operations with them. I have had a great offer from Hamilton and Balfour, which you'll probably have heard of. I can scarcely believe that even the effrontery of W r's roguery could have seriously set his face to such a scheme as that you mention. I scarce think it necessary, upon such a surmise, to write to Lord Milton ; but I shall drop a line to Mrs. Wedderburn or Miss Hepburn, in order to prevent any such foolish measure being heard with patience. I have not yet seen either Dr. Chandler or the Lions. All the ROBERTSON. 277 other scenes you recommend to me I have seen. I have heard the Bishops of Salisbury and Oxford. There was some elegance, a spice of drollery, and not a little buffoonery in the sermon of the latter ; and his audience admired and laughed, and were edified. Blair is but a ninny of an orator ; he makes his hearers serious, and sets them a- crying; but here they go to heaven, laughing as they go. You cannot imagine what strange characters I have met with, which I cannot now take off. I am a sort of domestic with Dr. Campbell, the best of all the authors I have seen.* I am often with Tucker of Bristol. I dined and drank claret with Douglas, the murderer of Bower." — " There were nine other persons in company (at another dinner), all of them retainers to the author or bookseller ; and I will draw you such a picture of that night, that you shall say the seeing of it alone was worth my coming to London. I wrote Bruce a long letter about news some days ago : you would probably meet with him and hear its contents. The Hanoverians are still making progress, as you will read more at large in the ' Chronicle/ The only thing which engrosses the talk of politicians is the flight of Bonneville. He was the officer who dissuaded the landing at Rochefort, and who, before the court-martial, gave evidence directly opposite to Clerk's. He went over to Holland ; was seen often at d'Affry's, the French Ambassador's : he told him, ' Sir, I do possess some merit; I saved one town to France, and three generals to England.' His evidence acquitted Mordant, &c. From Holland he went over to France. You may believe Pitf and Colonel Clerk, &c., enjoy this adventure, which is indeed a remarkable one. Last day I was in the House of Commons, of which I am made free by "- Unfortunately the MS. breaks off just as he was about to describe the debate. * The able author of the fine historical pieces in the edition 1740 of Harris's * Voyages.' Dr. R. always used to mention his Presbyterian horror of the " profane expletives " which he found formed a part of all English colloquial discourse in those days. t Sic. 278 ROBERTSON. The following letter gives a further account of the historian's progress in preparing for the publica- tion of his work. It is written to the same friend, Dr. Jardine : — « MY DEAR JOHN, " London, 20th April, 1759. i( I write this in the British Coffee-House,* in the middle of a company playing at cards and drinking claret. After this preamble, you are not to expect either a very long or a very distinct epistle. As to your letter, I postponed writing an answer to it, in expectation of hearing some account of the transactions of the Haddington Presbytery ; but as that has not come to hand, I must proceed to write without it. I am as much interested as you can possibly be in preventing the intended elevation of Turnstill to the Moderator's chair. But how could it possibly enter into the head of such a politician as you are, and one who has seen London too, that there was any method of engaging our laymen here to take part in a ques- tion about which they (laymen) are totally indifferent ? At the same time, I am earnest in giving opposition, and I think it may be made with great probability of success ; but I should be apt to imagine that neither Dick nor Hamilton are the proper candidates. You know neither of them stand well with Lord Milton ; j and if either you or I should give our interest or solicit for them, you know what a handle might be made of it. If Morrison, or some such grave, inoffensive, ecclesiastical personage could be set up, I join you with all my vigour. You must make the choice as well as you can. Why may you not stand yourself ? At any rate, fix upon some feasible man. Write a few letters, and endeavour to raise the jealousy of the brethren against a perpetual moderator, and I don't doubt of our defeating the Doctor. If we can dis- comfit him by our own strength, this will render him incon- siderable : all other methods of doing so would be ineffectual. * Much frequented then, as it still is, by Scotchmen. The gentle- woman who at that time kept it was sister to Bishop Douglas, and a person of excellent manners and abilities. | Then a kind of minister for Scotland, being Lord Bute's uncle. ROBERTSON. 279 " I have now brought my offers to a conclusion with An- drew Millar. After viewing the town, and considering the irresistible power of a combination of booksellers, I have agreed to sell him the property for £600. This, you see, is the sum I originally fixed upon as the full price of my work, and is more than was ever given for any book except David Hume's. You cannot imagine how much it has astonished all the London authors, nor how much Andrew Millar was astonished at the encomiums of my book which he got from people of rank. I have got some of the best puffers of England on my side. Mr. Doddington, Horace Walpole, Lady Hervey, and the Speaker are my sworn friends ; and you will wonder, even in this great place, how I have got Mary Queen of Scots to be a subject of conversation. Every body here approves of the bargain I have made with Millar, and I am fully satisfied of the prudence of my own conduct ; but of this I shall have full leisure to talk with you soon. The exploits which Carlyle and I have performed among the Dis- senters are beyond belief. Poor Dr. Chandler is humbled to the dust, and he feels it as much as other quack doctors feel their mortification. This day I signed my contract with Andrew Millar, and am, according to your advice, to be a Doctor of Divinity within six months, so that I shall take place immediately after Dr. Blair, as he taketh place immedi- ately after Dr. Turnstill. What great things have I to say of Mr. Pit,* who yesterday brought all the Tories to approve of continental measures as the only thing for the good of old England ! Yesterday I dined with Mr. Garrick, in spite of John Hyndmanf and the Presbytery of Dalkeith. To- morrow I go to Portsmouth, to wait on Admiral Hawke and see the E-oyal George. How much have I to tell you ! I ever am yours, « WM. E." The rank of the ' History of Scotland ' stands very high indeed among the most eminent of historical compositions. The philosophical spirit which per- * Sic. | A leader among the fanatical party in the Kirk. 280 ROBEKTSON. vades it, the enlarged views of polity in which it abounds, the sober and rational, but bold speculations with which it is variegated, and the constant references to authorities which accompany it, place it above the works of antiquity, deficient in all these particulars, altogether wanting in some of them. The skilful and striking delineations of individual character which are mingled with the narrative, but never overlaying it, and the reference to the histories of other countries which is introduced wherever it became necessary or in- structive, forms another high merit of the work. But it is as a history, and a history of Scotland, that its execution must mainly be regarded, and in this it is truly a great performance. It is difficult to admire sufficiently the graphic power which the historian displays in bringing before us the rude and stormy period he has chosen to describe — the strange mixture of simple barbaric manners in some classes with arti- ficial refinement in others — of poverty in the country with splendour at court, and among the chiefs — of great crimes with striking virtues — the morality of unprincipled and ferocious men with the vehement religious opinions of fanatics — the spectacle of a nation hardly half-civilized, barely emerging from a rude state, conducted by rulers, and disputed by factious leaders, with all the refinements and corruption of statesmen bred in the Italian courts. In the great staple of all historical excellence, the narrative, it has certainly never been surpassed. There is nothing obscure or vague, nothing affected or epigrammatic, nor is any sacrifice made of the sense to the phrase ; the diction is simple and pure, and soberly, if at all, adorned ; but ROBERTSON. 281 it is also striking ; the things described are presented in the clearest light, and with the most vivid, natural, and unambitious colouring, without exaggeration, ap- parently without effort ; like the figures of Raphael, which, for this reason, never captivate us so much on the first view as after we have repeatedly gazed upon them with still increasing wonder. The even flow of the story, the last perfection and the most difficult which the nar- rative art attains, is likewise complete. If not overlaid with ornament, nor disfigured by declamation, nor studded with points and other feats of speech, so neither is it broken by abrupt transitions and unseemly pauses, but holds its clear, simple, majestic course unin- terrupted and untroubled. The story of Livy does not more differ from that of Tacitus in all these essen- tials than the simple but striking narration of the Scotch historian from the tinsel, the epigram, the word-catching of Gibbon. For examples to illustrate the high merits of this narrative, we need not have recourse to a curious selec- tion of remarkable scenes or events, because the texture of the ' History ' in the ordinary portions of its fabric where the mere common annals are related, would be sufficient. There may, however, be no harm in not- ing the singular effect *of the story when Rizzio's murder is related, or Gowrie's conspiracy, or Mary's execution. The artistlike selection of particulars is to be marked in all these cases ; as in the first, Ruthven's figure clad in armour, and ghastly pale from his late illness ; in the second, the trembling of the mysterious armed man with a dagger near him, and a sword in the small study whither the Earl had led the King, 282 ROBERTSON. closing the doors behind them, and up a staircase ; in the third, the Queen's majestic air and noble dress, the pomander chain of her Agnus Dei round her neck, the beads at her girdle, the crucifix of ivory in her hand. By all these skilful selections we are made to see, as it were, the things represented to us, and the pen of the great historian produces the effect of the great artist's pencil, while its pictures are not subject to the destroy- ing influence of time.* There seems considerable reason to lament that an intimate acquaintance with the great scenes and cele- brated characters of history, in all ages, should have made the historian too familiar with the crimes on a great scale of importance, and therefore of wickedness, perpetrated by persons in exalted stations, so that he suppresses in recounting or in citing them the feelings of severe reprobation to which a more pure morality, a more strict justice, would certainly have given vent. It is painful to see him fall into the vulgar and perni- cious delusion which secures for the worst enemies of their species the praise and the increase of worldly greatness. It is equally painful to see the worst crimes, even of a more ordinary description, passed over in silence when they sully the illustrious culprit. J^et us * Hume, as well as Robertson, has given this scene of Mary's death ; the latter with by far greater effect. But it is singular that he should have left out her noble remonstrance with the commis- sioners when refused the assistance of her servants. It has a great effect in Hume. The observations of the latter on the trial are really beneath contempt. The gross errors into which he falls on the principles of evidence seem hardly credible, and arise from his careless habits, and from his undertaking rashly to deal with matters of which he was ignorant. ROBERTSON. 283 only, by way of example, and for explanation, survey the highly-wrought and indeed admirably composed character of Queen Elizabeth. It opens with enrolling Henry V. and Edward III. among " the monarchs who merit the people's gratitude ;" nay, it singles them out from among the list on which William III., Ed- ward I., and Alfred himself stand enrolled, and holds them up as the most gratefully admired of all for the " blessings and splendour of their reigns." Yet the wars of Henry V. are the only, and of Edward III. almost the only deeds by which we can know them ; or if any benefit accrued to our constitution by these princes, it was in consequence of the pecuniary diffi- culties into which those wars plunged them, but plunged their kingdoms too, so that our liberties made some gain from the dreadful expense of blood and of treasure by which those conquerors exhausted their dominions. Then Elizabeth is described as " still adored in England ;" and though her " dissimulation without necessity, and her severity beyond example," are recorded as making her treatment of Mary an exception to the rest of her reign, it is not stated that her whole life was one tissue of the same gross false- hood whenever she deemed it for her interest, or felt it suited her caprices, to practise artifices as pitiful as they were clumsy. But a graver charge than dissimulation and severity as regards her connexion with the history of Mary is entirely suppressed, and yet the foul crime is described in the same work. It is undeniable that Elizabeth did not cause her to be executed until she had repeatedly endeavoured to make Sir Amyas Paulett and Sir Drue Drury, who had the custody of her person, 284 ROBERTSON. take her off by assassination. When those two gallant cavaliers rejected the infamous proposition with indigna- tion and with scorn, she attacked them as " dainty " and " precise fellows/' " men promising much and perform- ing nothing ;" nay, she was with difficulty dissuaded from displacing them, and employing one Wingfield in their stead, " who had both courage and inclination to strike the blow." Then finding she could not commit murder, she signed the warrant for Mary's execution ; and immediately perpetrated a crime only less foul than murder, treacherously denying her handwriting, and destroying by heavy fine and long imprisonment the Secretary of State whom she had herself employed to issue the fatal warrant. History, fertile in its records of royal crimes, offers to our execration few such characters as that of this great, successful, and popular princess. An assassin in her heart, nay, in her councils and her orders ; an oppressor of the most unrelenting cruelty in her whole conduct ; a hypocritical dissembler, to whom falsehood was habitual, honest frankness strange — such is the light in which she ought to be ever held up, as long as humanity and truth shall bear any value in the eyes of men. That she rendered great services to her subjects ; that she possessed extraordinary firm- ness of character as a sovereign, with despicable weak- ness as an individual ; that she governed her dominions with admirable prudence, and guided her course through as great difficulties in the affairs of the state, and still more in those of the church, as beset the path of any who ever ruled — is equally incontrovertible; but there is no such thing as " right of set-off" in the judgments which impartial history has to pronounce — ROBERTSON. 285 no doctrine of compensation in the code of public morals ; and he who undertakes to record the actions of princes, and to paint their characters, is not at liberty to cast a veil over undeniable imperfections, or suffer himself like the giddy vulgar to be so dazzled by vulgar glory that his eyes are blind to crime.* A few months previous to the publication of his ' History,' Dr. Robertson, who had before received the degree of Doctor in Divinity from the University of Edinburgh, removed to that city, being presented to the kirk of the Old Grey Friars. In 1759 he was made one of the chaplains royal, a sinecure in the Scotch Church ; in 1762 he was appointed Principal of the University, and a proposition was now made, pro- ceeding from the King through his favourite minister, Lord Bute, who communicated it to Lord Cathcart, and he to the Principal, that if he would undertake to write the History of England, every source of information which the government could command would be laid open to his researches, and such provision settled upon him as might enable him to bestow his whole attention and time upon this important work without the inter- ruptions occasioned by his professional duties. This plan was so far favourably received that he expressed his willingness now to undertake the subject, as he could * Hume's highly-wrought character of Elizabeth, perhaps the finest of all his historical portraits, is liable to the same grave ob- jection ; somewhat mitigated by the circumstance that he seemed to lend less implicit credence to Davidson's testimony against her than Robertson does. It is remarkable that neither historian has remarked in Mary's vindication the undoubted right she had, without commit- ting an offence against the law or against morals, to join in any mea- sures of hostility against Elizabeth, who held her in an illegal custody. 286 ROBERTSON. not any longer come into conflict with his friend Mr. Hume, whose work would have been all published many years before the new ' History' could appear. His former objection of Mr. Hume's ' History' being then in progress when a similar plan was pressed upon him by the booksellers had thus been removed ; and though he declined on any account to lay down his clerical cha- racter, and withdraw from his station in the church, he had yet no objection, if he could still retain his con- nexion with that venerated establishment, to be relieved from the parochial labours connected with the cure of souls ; and provided Edinburgh should continue to be his place of residence, he purposed passing each year two or three months in London for the benefit of the collections offered to be placed at his service. It is probable that the retirement of Lord Bute from office, which happened soon after, put an end to this import- ant negotiation ; important in a very high degree to the literature, and, indeed, to the constitutional inte- rests of the country. Nothing more seems to have resulted from the correspondence except the reviving in his favour the place of historiographer for Scotland, to which he was appointed in 1764. But who that values the accuracy of historical narration, and sets a right estimate upon the benefits derived to our political system from a thorough investigation of the records and the events of former times, during which our mixed government was slowly formed and gradually matured, can avoid deeply lamenting that the subject of English history had not fallen into the hands of him who was, by a competent judge, though a rival author, justly called " the most diligent and most ROBERTSON. 287 faithful of penmen?" We should then have possessed a work of which the brilliant outside gloss being sus- tained by the intrinsic value of the coin, it would no longer have been necessary for the student to read one narrative for its dramatic effect, while he sought in another the real facts of the story, and to refuse giving the first praise of an historian to the first master of historical composition. Nor would the acquisition of an English history, at once readable and credible, have been purchased by the sacrifice of the other works with which this great writer, after the failure of the treaty, enriched our literature. It was part of the conditions which he imposed that he should first be allowed to finish his ' Charles V. ;' and when we reflect on ten years having elapsed after he finished his 'America,' without resuming his pen, there seems no reason to doubt that he could have written this and the English history also during the pe- riod between 1769, when ' Charles ' was published, and 1789, when he began the ' Disquisition on Ancient India/ The failure of the treaty, therefore, is a matter of unmingled regret ; and is one of the worst of the many mischiefs which we owe to the English plan of conducting government by the conflict of adverse parties, with the consequence inevitably flowing from it, of all the principles, and all the measures, and all the designs of one ministry becoming, as a matter of course, an object of suspicion, and even of dislike, to their successors. It is probable that he did not begin his second work for some little time after the publication of the first ; but from the correspondence just now referred to, we learn that in July, 1762, a third part of it was finished, 288 ROBERTSON. and that he reckoned two years more sufficient for its completion. In this he was deceived, whether it he that he underrated the labour required by the portion of his task still before him, or that he was interrupted in it (as has been supposed) by the fierce dissensions which during that period raged in the Scottish Church, and which must no doubt have occupied some portion of his leisure, though with so severe an economist of his time, and a mind so little liable to be disturbed, there seems little reason to think that these proceedings could seriously distract his attention from his studies for any consi- derable portion of the year. At length the public im- patience was gratified by the appearance of the work in 1769, exactly ten years after his ' Scotland/ Its success was not a matter of doubt, and it fully an- swered the expectations which had naturally been formed. The prevailing opinion places this work at the head of his writings ; and certainly, if the extent and importance of the subject be regarded, and the great value be considered of a clear and distinct narra- tive, embracing the history of Europe during the period when its different states assumed the position with relation to each other in which they now stand, and most of them also adopted the political system which is established for the government of their several affairs, there can be no comparison between this and any other of his works ; to which must doubtless be added, the far greater difficulty of executing so vast a plan, tracing the complicated parts of the great Euro- pean commonwealth in their connexion with each other, and drawing, as Mr. Stewart has happily ex- pressed it, a meridian line through modern history, to ROBERTSON. which all the branches of separate annals may be re- ferred. But though the same felicitous narrative is in this work to be always found, and though the first book contains the most perfect example of general or philosophical history anywhere to be seen, yet I hesi- tate greatly in preferring it as an historical composition to either its predecessor or its immediate successor. There are more remarkable beauties of a purely histo- rical kind in both of these, according to my humble judgment. As a whole, as a history of a country for a given period, I am much disposed to place his * Scot- land' first; while I conceive that the ' America' pre- sents particular passages, feats of narrative excel- lence, unrivalled by anything in either of the other works, perhaps not to be matched, and certainly not exceeded, by any other historical composition of any age. In proof of this last position I will refer to the fasci- nating account of Cortez's arrival at Mexico, and of his subsequent bold and masterly, though most cruel and profligate measures ; to the romantic history of Pedro de la Gasca's quelling by his individual wisdom and firmness the great rebellion of Peru ; but, above all, to the grand event, the most important recorded in the annals of our race, the discovery of the New World by Columbus. The skill with which this last narra- tive is managed, and the conduct of the story, may truly be pronounced matchless. I am now speaking merely of the composition. The dramatic effect of the whole is extraordinary. We are at first interested in Columbus's sagacity, and boldness, and science, by which he was led, through a course of private study u 290 ROBERTSON. and contemplation, to form the adventurous and novel opinion that the East Indies was to be reached by steering a westerly course from Europe across the At- lantic. His difficulties in obtaining the assent of his contemporaries to so strange a doctrine are then de- scribed, and our interest in his theory is increased. But the successive obstacles which he had to encounter in his efforts to obtain the assistance of various sove- reigns, that he might be enabled to test his theory by navigating the unknown and pathless ocean, wind up our anxiety to the highest pitch. We follow him to the Genoese senate, to the court of Portugal, to Eng- land, whither he had dispatched his brother, whose strange adventures among pirates and his utter indi- gence in London so as to make it necessary he should subsist by selling maps till he could scrape together enough to purchase decent clothes wherein he might appear before Henry VIII., form a striking episode in the narrative. Finally, we have his own arrival in Spain, and his constant repulses for twelve long years in all his attempts to make that country the richest and most glorious on the face of the earth. All these wander- ings and disappointments for so vast a portion of this great man's life create a breathless impatience for his success, when our wishes are at length crowned by the warm support of his steady patroness Isabella ; and he finally sets sail on the 3rd of August, 1 492. — Such is the man whose fortunes we are to follow, now far past the middle age, for he was in his fifty-sixth year, of which above twenty had been spent in preparing for his magnificent enterprise ; but full of the vigour of youth, in the height of his powerful faculties, and in- ROBERTSON. 291 spired with the sanguine temper which enables genius to work its wonders. The voyage is related with absolute clearness as re- gards all its nautical details, which are given so as to fix our attention without wearying it, and elucidate the narrative without encumbering it. But in the inci- dents of the passage we take the greatest interest, placed, as we feel ourselves to be, in the position of the navigators, to whom every occurrence was of moment, because everything was of necessity new. Their con- duct and their feelings, however, occupy us still more, for beside our sympathy with them, upon them the fate of the great enterprise depends. But one figure ever stands out from the group ; it is the great Captain who guides the voyage through the unknown ocean, and whom, beside his past history, we all the while feel by anticipation to be piercing through the night of ages to bring into acquaintance with each other the old world and the new. Upon his steady courage, undismayed by the dark uncertainty of all his steps, upon his fortitude which no peril can shake, his temper unruffled by all opposition, upon his copious resources under every difficulty, we dwell with the most profound attention ; sometimes hardly ven- turing to hope for his successful conquest over so many difficulties. The voyage meanwhile proceeds, and the distance from any known portion of the world becomes tremendous, while nothing but sea and air is on all hands to be discerned. At length some slight indications of approach to land begin to be perceived ; but so slight that universal despondency creates a general resistance, breaking out into actual mutiny. u2 292 ROBERTSON. Our anxiety for the result, and our interest in the great admiral, is now wound up to the highest pitch, when he obtains a promise of his crew persevering, " watch- ing with him " yet three days. The indications of land being not far off now become less doubtful ; and from among them are selected the more striking, closing with this picturesque passage : — " The sailors aboard the Nina took up the branch of a tree with red berries, perfectly fresh. The clouds around the setting sun assumed a new appearance ; the air was more mild and warm, and during the night the wind became unequal and variable." When we are thus in painful suspense, comes the crowning victory — at once of the great navi- gator who has happily traced the unknown ocean, and of the great historian who has strictly pursued his path, but so as to give the well-known truth all the interest and all the novelty of a romantic tale now first told. I beg any one who thinks these remarks overrate his merit, to mark the exquisite texture of the following sentences, in which the grand result, the development of the whole, is given ; and to mark the careful simplicity of the diction, the self- concealed art of the master, and his admirable selection of particu- lars, by which we, as it were, descend and perch upon the deck of the great admiral : — " From all these symp- toms Columbus was so confident of being near land, that on the evening of the 1 1th of October, after public prayers for success, he ordered the sails to be furled, and the ships to lie- to, keeping strict watch, lest they should be driven on shore in the night. During this interval of suspense and expectation no man shut his eyes; all kept upon deck, gazing intently towards that ROBERTSON. 293 quarter whence they expected to discern the land which had been so long the object of their wishes." It is a judicious thing, though it seems trivial, that he here breaks off j as it were, and begins a new paragraph ; and mark well its structure : — " About two hours before midnight Columbus, stand- ing on the forecastle, observed a light at a distance, and privately pointed it out to Pedro Guttierez, a page of the queen's wardrobe. Guttierez perceived it, and calling to Salcedo, comptroller of the fleet, all three saw it in motion, as if it were carried from place to place. A little after midnight the joyful sound si Land! Land I was heard from the Pinta, which kept always ahead of the other ships. But having been so often deceived by fallacious appearances, every man now became slow of belief, and waited in all the anguish of uncertainty and impatience for the return of day. As soon as the morning dawned, all doubts and fears were dis- pelled. From every ship an island was seen about two leagues to the north, whose flat and verdant fields, well stored with wood, and watered with many rivulets, *>> presented the aspect of a delightful country. The t crew of the Pinta instantly began the Te Deum, as a hymn of thanksgiving to God, and were joined by those of the other ships, with tears of joy and trans- ports of congratulation. This office of gratitude to Heaven was followed by an act of justice to their com- mander. They threw themselves at the feet of Co- lumbus with feelings of self-condemnation mingled with remorse. They implored him to pardon their ignorance, incredulity, and injustice, which had created him so much unnecessary disquiet, and had so often ob- 294 ROBERTSON. structed the execution of his well-concerted plan ; and passing in the warmth of their admiration from one extreme to another, they now pronounced the man whom they had so lately reviled and threatened, to be a person inspired by Heaven with sagacity and fortitude more than human in order to accomplish a design so far beyond the ideas and conception of all former ages." In like manner is the landing and the meeting with the natives painted rather than described. The impression made, for instance, by the Spaniards on the minds of these simple folk shows that the great writer can place himself in the position of the savage as well as the sage. " The vast machines in which they had traversed the ocean, that seemed to move upon the waters with wings, and uttered a dreadful sound like thunder, accompanied with lightning and smoke, struck them with such terror, that they began to respect their new guests as a superior order of beings, and concluded that they were children of the sun, who had descended to visit the earth." The simple language of these passages, to make but one observation, is remarkable ; and their dignity is with this perfect plainness perfectly sustained. It is always in such language that a master of diction will make his impression ; and the near approach of any catastrophe, whether awful or pathetic, may always be suspected when the language becomes very simple, and the particulars begin to abound. There is but one word above the most homely style of the most ordinary conversation in all that I have cited. The fields are " verdant," not green ; and this word is cor- rectly chosen for the rhythm, which would not allow ROBERTSON. 295 a monosyllable. Possibly " descend " was unnecessary ; " come down " would have been sufficiently sustained. The technical words "lie-to "and "ahead" were in like manner necessary, because there is ridicule attached to speaking of a ship " stopping," or one being before another, as on the road ; besides that these phrases have been imported from nautical language, and are now naturalised on shore. The effect which the passage adverted to is calcu- lated to produce on readers of understanding and of feeling was once remarkably seen by me, when I made my illustrious and venerated friend Lord Wellesley attend to it. He told me next day that he had never been so much moved by any modern writing ; that he had shed tears while he read it, and that it had broken his rest at night. If the word dramatic has been applied to this nar- rative, it has been advisedly chosen ; because no one can doubt that, with the most scrupulous regard to the truth, and even to the minute accuracy of history, this composition has all the beauties of a striking poem. To judge of its merits in this respect, I will not compare or rather contrast it with the Histories of Oviedo, or Herrera, or Ferdinand Columbus, or even with the far better composition of Dr. Campbell, or whoever wrote the history of the discovery in Harris's ' Bibli- otheca Itinerantium,'* nor yet with the ambitious but * This work, in two folio volumes, contains some admirable his- torical pieces. Burke's 'European Settlements' is very much taken from it. I refer to the edition of 1740, by Dr. Campbell, whose acquaintance Dr. Robertson appears by his ' Letters ' above cited to have had great pleasure in making when he visited London. 296 ROBERTSON. worse written narrative of Mr. Washington Irvine, in his 'Life and Voyages of Columbus;'* but I will refer to a poetical work written purely for effect, and * It is no part of my intention to underrate the merits of this very popular author ; but I speak of the manner in which he has treated the subject ; and coming after so great a master, it was not judicious in him to try aftereffect, instead of studying the chaste simplicity of his pre- decessor. These are a few of his expressions : — The ships " were ploughing the waves ;" Columbus was " wrapped in the shades of night ;" he " maintained an intense watch ;" he " ranged his eye along the dusky horizon ;" he beheld " suddenly a glimmering light." Ro- bertson had never thought of saying " suddenly," as knowing that light must of necessity be sudden. Then the light has " passing gleams ;" his feelings " must have been tumultuous and intense," con- trary to the fact, and to the character of the man ; " the great mystery of the ocean was revealed ;" " what a bewildering crowd of conjectures thronged on his mind !" All this speculation of the writer to insure the effect, Dr. Robertson rejects as fatal to effect, and gives only what actually happened. Finally, he was possibly to find " the morning dawn upon spicy groves, and glittering fanes, and gilded cities." Surely no one can hesitate which of the two pictures to prefer. If the one is not absolutely tawdry, the other is assuredly more chaste. To compare the two pieces of workmanship is a good lesson, and may tend to cure a vitiated taste (Book iii. chap. 3). To take only one in- stance : — " About two hours before midnight, Columbus, standing on the forecastle, observed a light at a distance, and presently pointed it out to Pedro," &c. Thus Robertson. Irvine says, " Wrapped from observation in the shades of night, he maintained an intense and unremitting watch, ranging his eye along the dusky horizon. Suddenly, about ten o'clock, he thought he beheld a light glimmer- ing at a distance." Can any one doubt which of the two passages is the most striking — the chaste and severe, or the ornamented and gaudy and meretricious? The account of Robertson makes the ships lie-to all night. Irvine either makes them lie-to, and after- wards go on sailing rapidly, or the lying-to was the night before, and they sailed quicker the nearer they came to land, and in the dusk. The one makes them only see the shore after dawn ; the other makes them see it two leagues off, in a dark night, at two in the morning, within the tropics. ROBERTSON. 297 of which the author was at full liberty to indulge his fancy in selecting, or indeed in imagining the facts and the scenes he represented. That author, too, is a poet of no mean fame, the late Mr. Southey, who has sung the discovery of America by Madoc ; and his verse is much less fine, and as a poem, than the history which I have been asking the reader to contemplate. The poet leaves out all the most picturesque matters, the truly poetical matters ; and instead of them all, after a mutiny he raises a storm, which so cripples the ships that the seamen cannot sail back if they would. All he says of the discovery is, that the commander watched upon deck till dawn, and then saw the distant land arise like a grey cloud from the ocean. He also makes the sea shallow, though at such distance as that the land looks like a cloud. It really should seem as if he had refrained from looking at Robertson's ' History ' because he was to write a poem on the sub- ject, as he tells us he did from reading Voltaire's poem before, and, indeed, also after he wrote ' Joan of Arc.' There is one reflection which arises very naturally on examining the rare excellence of such narratives as that of Pedro de la Gasca and Columbus's voyage. The subject of the latter is altogether free from warlike interest ; of the former, nearly so ; and of neither scene is the effect at all heightened by the vices or the ex- cesses of the actors. Then who can find any more interesting narrative of events where great crimes are the subject, and who can doubt that the same pen which could so admirably paint the scenes, peaceful and guiltless, which compose the subject of such historical pictures, could in like manner have lent an interest 298 ROBERTSON. to others of a like kind, without exalting, at the expense of public virtue, the merits of wicked men? But if it be said that the quieting a great republic, or dis- covering a new hemisphere, are acts of such interest as lend themselves to the historian's pen, and are easily made to rivet our attention, surely the same pen which described them can represent even the wars that deso- late the earth, and the crimes that disgrace humanity, in such colours as shall at once make us see the things per- petrated, and yet lament the wretchedness of the events, and execrate the cruelties or scorn the perfidies of the criminals, instead of making us, with a preposterous joy and a guilty admiration, exult in the occurrence of the one, and revere the memory of the other. Refer- ence has been made already to the Plantagenet Prince and the Tudor Princess, so much the theme of admir- ation with historians for great capacity, crowned with dazzling success. But why could not the diction of Hume and of Robertson have been employed for the far more worthy purpose of causing men to despise the intrigues and execrate the wars of such rulers ? The same events had then studded their page, the same picturesque details given it striking effect, the same graphic colours added life to it, and yet the right feelings of the reader would have been exerted and cherished ; nor would the historians have made them- selves accomplices with the vulgar in the criminal award of applause and of fame, by which the wicked actions of past times are rewarded, and the repeti- tion of the same offences encouraged. Historians, too, are capricious and uncertain in their panegyrics. Some princes of undoubted genius, of great ROBERTSON. 299 courage, of singular skill in conquest and in government, nay, even who have rendered services to mankind, not- withstanding their vices, are set apart to be loaded with obloquy — quite just in their instance, but incon- sistent enough with the suppression of all reprobation in other cases of less atrocity, indeed, yet of deep shades of guilt. The Borgia family are proverbial for profligacy and cruelty ; yet both father and son showed talents of the highest order, to which the latter added great bravery, while the family were generous protect- ors of learning, especially of the study of jurisprudence, and do not seem to have misgoverned the people of their states more than others of the same age and coun- try, their violence being exhausted on foreign princes and on their own feudal barons.* Of them, however, all anecdotes without evidence are believed. So the least credible stories of our Richard III. are easily received without proof, and he is universally regarded as a monster living in the habitual commission of murder ; yet his capacity and his courage were universally ad- mitted to be of the very highest order, and his reign conferred great advantages on the jurisprudence of England, while the nobles only, and not the com- munity at large, suffered from his tyranny. Is it not somewhat inconsistent in the same historians who are so hostile to these great bad men that they can discover no merit in them, to be so dazzled by the battles of the Plantagenets and the policy of the Tudors that they can discover no blame in the sanguinary ambition of * Livy's character of Hannibal has been, and not unjustly, likened by Hume to Guicciardini's account of Alexander VI. 300 ROBERTSON. the one and the tyranny and perfidy of the other ? Henry VIII., indeed, by his cruelty to his wives, has been deprived of much palliation which otherwise his abilities and his accomplishments would have obtained for his despotic life, his numerous judicial murders actually perpetrated, as well as his plot for an ordinary assassination, that of Cardinal Beaton, only prevented by his own decease. But his daughter, who was as tyrannical to the full, and only restrained by the reli- gious difficulties of her position, who was a model of falsehood in all its more hateful and despicable forms, who had all the guilt of murder on her head, and was only saved from its actual perpetration by hav- ing a Paulett for her agent, whom she would fain have suborned to commit it, instead of a Tyrrel, is loaded with the praise due to the most pure and vir- tuous of sovereigns, because she had talents and firm- ness and ruled successfully in difficult times. It is not, however, merely by abstaining from indiscriminate praise, or. by dwelling with dispro- portioned earnestness upon the great qualities, and passing lightly over the bad ones, of eminent men, and thus leaving a false general impression of their conduct, that historians err, and pervert the opinions and feelings of mankind. Even if they were to give a careful estimate of each character, and pronounce just judgment upon the whole, they would still leave by far the most important part of their duty unperformed, unless they also framed their narrative so as to excite our interest in the worthy of past times ; to make us dwell with delight on the scenes of human improve- ment ; to lessen the pleasure too naturally felt in con- ROBERTSON. 301 templating successful courage or skill, whensoever these are directed towards the injury of mankind ; to call forth our scorn of perfidious actions, however successful ; our detestation of cruel and bloodthirsty propensities, however powerful the talents by which their indul- gence was secured. Instead of holding up to our admiration the " pride, pomp, and circumstance of glorious war," it is the historian's duty to make us regard with unceasing delight the ease, worth, and happiness of blessed peace ; he must remember that " Peace hath her victories, No less renown'd than War :"* and to celebrate these triumphs, the progress of science and of art, the extension and security of freedom, the improvement of national institutions, the diffusion of general prosperity — exhausting on such pure and wholesome themes all the resources of his philo- sophy, all the graces of his style, giving honour to whom honour is due, withholding all incentives to misplaced interest and vicious admiration, and not merely by general remarks on men and on events, but by the manner of describing the one and recording the other, causing us to entertain the proper sentiments, whether of respect or of interest, or of aversion or of indifference, for the various subjects of the narration. It is not to be denied, that history written in this spirit must differ materially from any of which we have as yet the experience : it is only to be lamented that those great masters, whose writings we have been contemplating, did not consecrate their mighty talents * Milton. 302 ROBERTSON. to so good a work. To the historians of all ages joining with the vulgar, and, indeed, writing as if they belonged themselves either to the class of am- bitious warriors and intriguing statesmen, or to the herd of ordinary men whom successful crimes de- frauded at once of their rights and their praises, may be ascribed by far the greater part of the en- couragement held out to profligate conduct in those who have the destinies of nations in their hands. At all events, this is certain : if they could not eradicate the natural propensity in the human mind towards these errors when unrefined, they might have en- lightened it, and have gradually diffused a sounder and better feeling. So deeply have I always felt the duty of attempting some such reformation in the historical character and practice, that I had begun to undertake the reigns of Henry V., of Elizabeth, and of Alfred, upon these great principles. A deep sense of the inadequate powers which I brought to this hard task, would probably have so far grown upon me as its execution advanced, that I should have abandoned it to abler hands ; but professional, and afterwards judicial, duties put an end to the attempt before it had made any considerable progress. Nevertheless, I found no small reason to be satisfied of success being attainable, when I came narrowly to examine the interesting facts connected with national improvement and vir- tuous conduct ; and I am sure, that whoever may repeat the attempt will gather encouragement from the proof, which I have drawn from the master-piece we have been contemplating, that the events and ROBERTSON. 303 characters of past times lend themselves to an affecting narrative, conducted on right principles. The last work of Dr. Robertson, and which he published little more than two years before his death, was his ' Disquisition concerning India/ It is an able and most learned inquiry, critical and historical, into the knowledge of India possessed by the ancient nations who dwelt on the Mediterranean Sea. No- thing can be more unjust than the notion that this work is so incorrect, or grounded on information so imperfect, as to have been superseded by more full and accurate books since published. There is no doubt that the account of the native customs and manners given in the Appendix has been rendered less useful by the more copious details since obtained, and that some dispute has been made of the views which the author occasionally takes in that Appendix ; but the Disquisition itself remains perfectly untouched by any controversy ; and so far is it from having been super- seded, that no other work has ever been since given to the world on the same subject. It is, from its accuracy, its knowledge of the ancient writings, its judicious reasoning and remarks, as well as its admi- rable composition, quite worthy of a place by the author's former and more celebrated writings ; and it proves his great faculties to have continued in their entire vigour to the latest period of his life. It remains to speak of Robertson's style. No one ever doubted of its great excellence, but it has some- times been objected to as less idiomatic and more laboured than is consistent with the perfection of com- position. The want of purely idiomatic expressions 304 ROBERTSON. is the almost unavoidable consequence of provincial education and habits. Many forms of speech which are English, are almost entirely unknown in the remote parts of the kingdom ; many which are per- fectly pure and classical, a person living in Scotland would fear to use as doubting their correctness. That Robertson, however, had carefully studied the best writers, with a view to acquire genuine Anglicism, cannot be doubted. He was intimately acquainted with Swift's writings ; indeed, he regarded him as eminently skilled in the narrative art. He had the same familiarity with Defoe, and had formed the same high estimate of his historical powers. I know, that when a Professor in another University consulted him on the best discipline for acquiring a good narrative style, previous to drawing up John Bell of Antermony 's 'Travels across Russia to Tartary and the Chinese Wall,' the remarkable advice he gave him was to read f Robinson Crusoe' carefully ; and when the Professor was astonished, and supposed it was a jest, the his- torian said he was quite serious : but if ' Robinson Crusoe' would not help him, or he was above studying Defoe, then he recommended ' Gulliver's Travels.' The works of Dr. Robertson involved him, as was to be expected, in some controversy of considerable violence ; but as all men have done ample justice to his diligence in consulting his authorities, and as all candid men have testified to his strict impartiality, the attacks which were made upon him, and to which he never would offer any answer, proceeded from two unworthy sources — the bitter zeal of party, and the still more bitter enmity of personal spleen. The Jacobites have ROBERTSON. 305 ever regarded Queen Mary's honour as an integral part of their political faith ; and they could not forgive any one who, with whatever leaning towards a prin- cess the victim of such cruel treatment, and the sufferer under misfortunes so long and so heavy, and with whatever disposition to free her from any charges unsupported by evidence, had yet performed faithfully his duty as an historian and as a moralist, of condemn- ing profligate conduct, and exposing gross imprudence amounting to absolute infatuation even if guilt be denied. Nothing could have satisfied the blind zeal of this faction, neither respectable from number, nor distinguished for ability, but acquitting Mary of every charge that she did not herself confess, and then approving of her marriage with the murderer of her husband within three months of his assassination. By far the ablest of the writings which the contro- versy produced, was the f Inquiry' of Mr. Tytler, a lawyer by profession, a man of strong prejudices, but equally strong understanding, and a very diligent and accurate investigator of particular facts. The most learned, but the most repulsive from its dogmatism and its overbearing tone, was the 'Vindication' of Mr. Whittaker, a clergyman of the Church of Eng- land, settled in Cornwall, and remarkable for his industrious study of ancient British antiquities. With Mr. Hume Dr. Robertson likewise differed, but it was in an opposite direction : he could not yield to that able writer's arguments in proof of Mary's having been accessary to the Babington conspiracy ; and though he minutely considered both the new x 306 ROBERTSON. evidence supposed to be printed in Murdin's ' State Papers' since the ( History of Scotland' was composed, and also carefully examined again all his authorities on the points on which he had been assailed by the Jacobite forces, yet, with the exception of a few unim- portant errors or oversights, which he corrected, he adhered to his original statements, well weighed and maturely framed as they had, in all instances, been. The personal resentment of an able but unprincipled man was the cause of the most unworthy and un- measured attacks, both on his ' Scottish History' and on his subsequent publications. Gilbert Stuart was a person of undoubted parts, but of idle and dissipated habits. An able and learned work which he had published at a very early age, on the t History of the British Constitution,' made the University of Edin- burgh give him the degree of Doctor of Laws, when little more than one and twenty ; and he soon after published his ' View of Society in Europe/ being an historical inquiry concerning laws, manners, and go- vernment. Immediately after this he was a candidate for the Professorship of Public Law, in the University, and he fancied that he owed his rejection to the in- fluence of the Principal. Nothing could be more fitting than that such should be the case; for the life of Stuart was known to be that of habitual dissipation, in the intervals only of which he had paroxysms of study. To exclude such a person from the professor's chair would have been a duty incumbent upon the head of any university in Christendom, whatever, in other respects, might be his merits ; but no admission ROBERTSON. 307 was ever made by the Principal's friends that he had interfered, or indeed that the opinions and inclinations of the magistrates, who are the patrons, rendered any such interference necessary. But the disappointed candidate had no doubt upon the subject, and he set no bounds to his thirst of revenge. He repaired to Lon- don, where he became a writer in reviews, and made all the literary men of Edinburgh the subjects of his envious and malignant attacks, from 1768 to 1773 ; the editors of these journals, as is usual with persons in their really responsible situation, but who think they can throw the responsibility upon their unknown contributors, never inquiring whether the criticisms which they published proceeded from the honest judg- ment or the personal spite of the writers. He returned to Edinburgh, and set up a magazine and review, of which the scurrility, dictated by private resentments, was so unremitting that it brought the work to a close in less than three years, when he returned to London, and recommenced his anonymous vituperation of Scot- tish authors through the periodical press. He also published in 1779, 1780, and 1782, three works : one on the * Constitutional History of Scotland/ being an attack on Dr. Robertson's first book ; another on the ' History of the Reformation in Scotland ;' and the third on the 'History of Queen Mary,' being also an elaborate attack upon the Principal. The ability and the learning of these works, and their lively and even engaging style, has not saved them from the oblivion to which they were justly consigned by the manifest indications prevailing throughout them all, of splenetic temper, of personal violence, and of a constant disturb- x2 308 ROBERTSON. ance of the judgment by these vile, unworthy passions.* The same hostility towards the person of the Princi- pal even involved this reckless man in a quarrel with his eldest son ; it led to a duel, in which neither party was hurt. An accommodation having taken place on the field, I have heard Stuart's second say that he was obliged, knowing his friend's intemperate habits, to oppose the proposal which he made with his usual want of conduct, and indeed of right feeling, that all the parties should dine together on quitting the field. That second, an able and an honourable man, always admitted Stuart's unjustifiable conduct towards the historian, one of whose nieces he (the second) after- wards married. Stuart's dissipation continued un- broken, excepting by his occasional literary work, and he died of a dropsy, in 1786, at the early age of forty. • Others, far more deserving of attention, have raised an objection to the * History of America,' from which it is difficult to defend it. There is induced by the narrative, in the mind of the reader, far too great sympathy with the conquerors of the New World. * Next to the Principal no one was more bitterly assailed than my late venerated friend and master, Dr. Adam, rector of the High School. His admirable ' Grammar' was received universally by the literary and didactic world (by the scholar as well as the teacher) with the approbation which it so well deserved. But it had one fault — it was on a subject on which Stuart's cousin, Ruddirnan, had published a book. This was enough to enlist Stuart's ferocity against both the work and the writer. He published anonymous reviews without end, and he also published, under the name of Busby, a bitter attack upon the personal peculiarities of Dr. Adam. Every one felt unmingled disgust at such base and unprincipled proceed- ings, and the Rector, like the Principal, gave the unworthy author the mortification of leaving his assaults unanswered. ROBERTSON. 309 This may in part be palliated by the feeling so diffi- cult for any historian to avoid, and which leads him to paint in interesting, if not in attractive colours, the deeds and the heroes of his story. But the atro- cious crimes of those Spanish invaders, who, with a combination of fanatical violence and sordid avarice, subjugated or extirpated unoffending millions because of their pagan ignorance and their precious mines, — those bigoted furies who poured out the blood of men like water, in order to establish the Gospel of peace and good will towards man,— those monsters of cruelty, who, after wearying themselves with massacre, racked their invention for tortures, which might either glut their savage propensities or slake their execrable thirst of gold, — all ought to have called for reprobation, far more severe than any which the historian of their guilt has denounced against them. This is a great stain upon the work, and it can only be palliated by the excuse already offered, — an excuse by which the stain never can be wiped out. After the Principal's publication of ' Charles V.,' and while he was writing the 'America,' no event of im- portance occurred in his life, which was tranquil and dignified, occupied only with his duties as head of the University, where the habitual deference of his col- leagues rendered the administration of its concerns easy and prosperous, diversified also with his conduct of the Scottish church, now under his guidance, un- opposed by any rival. He occasionally visited London, where he was received by all the more distinguished 310 ROBERTSON. characters, whether statesmen or men of letters, with the highest distinction ; and the charms of his con- versation, at once easy, lively, good-humoured, and yet perfectly dignified as became his sacred profession and his elevated position, added greatly to the interest that naturally arose from his literary renown. In 1778, the concessions to the English and Irish Roman Catholics, by repealing the most oppressive parts of the penal laws, suggested to those of Scotland the obtaining a similar boon, or rather a similar act of jus- tice. The Principal approved and supported their claims. An alarm was excited, and the Puritanical party in the General Assembly urged the adoption of a remon- strance against the proposed measure, but the Princi- pal's salutary interference occasioned its rejection. The alarm was, however, stimulated by all the means to which the unscrupulous fury of religious faction has recourse ; and so great a dread of violence was excited, that the Catholics at once abandoned their attempt. Their concessions, however, came too late to allay the popular ferment which the Puritans had raised ; and a fanatical mob attacking the Protestant chapels at Edinburgh, burnt one and pulled down another, then, proceeding to the college, were about to assail the Principal's house, which they beleaguered, with the most savage imprecations against him, but having had notice of their approach he had withdrawn his family, and a body of soldiers stationed there saved the build- ing and the rest of the university. At the next Assembly in 1780 he made a speech of singular elo- quence, declaring his unaltered opinion on the justice of the measure, but adding that before the riots he ROBERTSON. 311 had been disposed to recommend a postponement of it until time should be given to enlighten the public mind, and free it from the gross delusions under which it had been brought through the acts of unprincipled men. This speech is given with tolerable fulness in the Scotch Magazine for that year, and it fully justifies the exalted opinion traditionally entertained of the Principal's oratory. He declared on this memorable occasion his intention to withdraw from public life, and stated that his friends well knew this resolution had been taken some time before the late controversy. Nothing memorable occurred to this eminent and virtuous person after the period to which reference has now been made. A matrimonial alliance between his eldest daughter and Mr. Brydone, the celebrated traveller, a gentleman, too, known for his scientific pursuits, as well as distinguished for his amiable manners and kindness of disposition, had contributed materially to her father's happiness ; and he liked to pass a few weeks in the summer or autumn at the de- lightful residence of Lennel on the southern border, where that excellent person lived, and where as late as 1814 he ended his days. In the autumn of 1791 the Principal's health first began to fail; and a jaundice, proceeding from an affection of the liver, brought him early in 1793 to a state of weakness which left no hope of his recovery. He bore his infirmity with entire patience, and beheld the prospect of death, which was for many months before him, with unshaken fortitude. A month or two previous to his decease, he was removed to Grange House, in the neighbourhood of Edinburgh. Profes- 312 ROBERTSON. sor Stewart there saw him more than once ; and far from avoiding the subject, he said it would be satisfac- tory to him that his friend should write the account of his life — it being, according to the usage of the Royal Society (of Edinburgh), customary to give in their ' Transactions' the lives of deceased members who have attained distinction by their works. On another occa- sion an observation was made on the fruit-trees then in blossom ; and he alluded, with cheerful composure, to the event which must happen before they came to their maturity, and prevent him who now looked upon the flower from seeing the fruit. His strength of body gradually declining, though his mind remained quite entire, he died on the llth June, 1793, in the 72nd year of his age. His funeral in the Grey Friars church-yard was attended by the professors, the magis- trates of the city, the heads of the law, and many of the other respectable inhabitants of Edinburgh. It was, as I can testify, a scene peculiarly impressive to all who witnessed it, from the sterling virtue as well as the great celebrity and intrinsic merits of the illustrious deceased. The history of the author is the history of the indi- vidual, excepting as regards his private life and his personal habits : these were in the most perfect de- gree dignified and pure. Without anything of harshness or fanaticism, he was rationally pious and blamelessly moral. His conduct, both as a Christian minister, as a member of society, as a relation, and as a friend, was wholly without a stain. His affections were warm, they were ever under control, and therefore equal and steady. His feelings might pass for being less strong ROBERTSON.' 313 and lively than they were, partly because he had an insuperable aversion to extremes in all things, partly because, for fear of any semblance of pretension, to which he was yet more averse, he preferred appearing less moved than he really was, in order to avoid the possibility of feeling less than he externally showed. But he was of opinions respecting conduct which led to keeping the feelings under curb, and never giving way to them ; he leant in this towards the philosophy and discipline of the Stoics ; and he also held, which was apt to beget the same mistake as to the warmth of his heart, that exhibitions of sorrow, any more than of boisterous mirth, were unfit to be made ; that such emotions should as far as possible be reduced to mode- ration, even in private ; but that in society they were altogether misplaced and mistimed. He considered, and rightly considered, that if a person labouring under any afflictive feelings be well enough at ease to go into company, he gives a sort of pledge that he is so far recovered of his wound, or at least can so far con- ceal his pains, as to behave like the rest of the circle. He held, and rightly held, that men frequent society, not to pour forth their sorrows, or indulge their un- wieldy joys, but to instruct, or improve, or amuse each other, by rational and cheerful conversation. For himself, when he left his study, leaving behind him, with the dust of his books, the anxious look, the wrinkled brow, the disturbed or absent thoughts, he also expected others to greet his arrival with the like freedom from cares of all sorts, and especially he dis- liked to have his hours of relaxation saddened with tales of misery, interesting to no one, unless, which is 314 ROBERTSON. never the object of such narratives, there be a purpose of obtaining relief. His conversation was cheerful, and it was varied. Vast information, copious anecdote, perfect appositeness of illustration, — narration or description wholly free from pedantry or stiffness, but as felicitous and as striking as might be expected from such a master — great liveli- ness, and often wit and often humour, with a full dis- position to enjoy the merriment of the hour, but the most scrupulous absence of everything like coarseness of any description — these formed the staples of his talk. One thing he never tolerated any more than he did the least breach of decorum ; it was among the few matters which seemed to try his temper — he could not bear evil speaking, or want of charity. No one was likely ever to wrangle with another before him ; but he always put down at once any attempt to assail the ab- sent. His own nature was singularly charitable and kindly ; he always viewed the conduct of others in the least unfavourable light ; and when he heard any ob- jections urged, he would suggest something that at least left the blame mitigated when it could not be warded off or made doubtful. Of course, this remark applies to cases where the matter was ambiguous, and the general character and conduct were good. No man ever expressed a greater abhorrence of anything plainly bad, or a nobler scorn of anything mean ; and his sen- tence went forth in such cases with an awful and an overpowering force. His very decided opinions on all subjects of public interest, civil and religious, never interrupted his friendly and familiar intercourse with those who held ROBERTSON. 315 different principles. With his colleague, Dr. Erskine, leader of his antagonists in the Church, he lived upon terms of uninterrupted friendship, as that «great pres- byter feelingly testified on preaching his funeral sermon. With Mr. Hume his intimacy is well known. His political principles were those of a mo- derate Whig, a Whig of 1688, as he used to express it ; but no man held in greater contempt the petty manoeuvres of party. Horace Walpole has thought lit to record a dialogue as having passed between them, in which he makes the Principal say, " You must know, sir, that I am a moderate Whig;" and himself answer, " Yes, Doctor, a very moderate Whig, I'll engage for it" — a sneer not likely to have been risked by such an amateur with such an artist. What the great historian intended by using the word " moderate'* plainly was to guard himself against being supposed to enter into the squabbles of faction, and partake of its blind fury in a degree unsuited to his station. On religious matters he ever expressed himself with solemnity and warmth. While he was wishing well to liberty in France, before the excesses that profaned its name, and indeed before the revolution broke out, he was deploring the irreligious tone of French litera- ture : " Really," said he, " one would think we were living under a new dispensation." Of American independence he was the warm friend ; but Washing- ton's character was far more to his mind than Franklin's, of whose violence and contempt of revealed religion he had formed a very unfavourable opinion. His manner was not graceful in little matters, though his demeanour was dignified on the whole. In public 316 ROBERTSON. it was unimpassioned till some great burst came from him ; then it partook of the fire of the moment, and soon relapsed into dignified composure. In private it had some little awkwardnesses, not very perceptible except to a near and minute observer. His language was correct and purely English, avoiding both learned words and foreign phraseology and Scottish expres- sions, but his speech was strongly tinged with the Scottish accent. His voice I well remember, nor was it easy to forget it ; nothing could be more pleasing. It was full and it was calm, but it had a tone of heartiness and sincerity which I hardly ever knew in any other. He was in person above the middle size — his features were strongly marked — his forehead was high and open — the expression of his mouth was that of repose, of meditation, and of sweetness at the same time. The portrait, by Sir Joshua Reynolds, is a strik- ing likeness, and it is the one which is engraved. I never knew an instance, I should say, of so strong a resemblance as that which his eldest daughter, Mrs. Brydone, bore him. In her latter years, too, the sound of her voice was nearly his own. The only particulars of his manners and person which I recollect are his cocked hat, which he always wore, even in the country ; his stately gait, particularly in a walk which he loved to frequent in the woods at Brougham, where I at- tended him once while he visited there, and in which he slowly recited sometimes Latin verses, sometimes Greek ; a very slight guttural accent in his speech, which gave it a peculiar fulness ; and his retaining some old-fashioned modes of address, as using the word " madam" at full length ; and, when he drank wine ROBERTSON. 317 with any woman, adding, " My humble service to you." When in the country he liked to be left entirely to himself in the morning, either to read or to walk or to drive about ; and he said that one of his great enjoy- ments at Lennel was Mr. Brydone and himself doing precisely each as he chose, and being each as if the other were not in the same house. To give any notion of the anecdotes, simple, racy, unpretending, which he would introduce when per- fectly apposite to the subject matter, would not be easy. Good nature and good humour prevailed through his conversation, in which there was nothing ambitious or forced, or any thing to show a desire of display. It always seemed as if he merely wished to enjoy him- self, and contribute his share to the enjoyment of others. The late Lord Meadowbank, a kinsman of his, and indeed his ward, when preparing his Lectures on General History, of which he was Professor, asked him if he had ever remarked how very superficial Mr. Hume's Anglo-Saxon period is, more so than the other parts, though the last written, of his 'History?' " Why, yes, I have," said the Principal ; " but the truth is, David (so he always called him) had the most unfortunate thing happen to him that can 'befall an author — he was paid for it before he wrote it." ( 318 ) APPENDIX. ADDRESS OF PRINCIPAL ROBERTSON ON LAYING THE FOUNDA. TION STONE OF THE EDINBURGH COLLEGE, 1791. — (LORD NAPIER WAS THE GRAND MASTER OF THE MASONS.) " MY LORD, "From very humble beginnings the University of Edinburgh has attained to such eminence as entitles it to be ranked among the most celebrated seminaries of learning. Indebted to the bounty of several of our sovereigns ; distin- guished, particularly, by the gracious prince now seated on the British throne, whom, with gratitude, we reckon amongst the most munificent of our royal benefactors ; and cherished by the continued attention and good offices of our honourable patrons,* this University can now boast of the number and variety of its institutions for the instruction of youth in all the branches of literature and science. " With what integrity and discernment persons have been chosen to preside in each of these departments, the character of my learned colleagues affords the most satisfying evidence. From confidence in their abilities and assiduity in discharg- ing the duties of their respective offices, the University of Edinburgh has not only become a seat of education to youth in every part of the British dominions, but, to the honour of our country, students have been attracted to it from almost every nation in Europe, and every state in America. " One thing still was wanting. The apartments appropriated for the accommodation of professors and students were so ex- tremely unsuitable to the flourishing state of the University, that it had long been the general wish to have buildings more decent and convenient erected. What your Lordship has now done gives a near prospect of having this wish accom- * The magistrates of the city. KOBERTSON. 319 plished ; and we consider it as a most auspicious circumstance that the foundation stone of this new mansion of science is laid by your Lordship, who, among your ancestors, reckon a man whose original and inventive genius places him high among the illustrious persons who have contributed most eminently to enlarge the boundaries of human knowledge. "Permit me to add what I regard as my own peculiar feli- city, that, by having remained in my present station much longer than any of my predecessors, I have lived to witness an event so beneficial to this University, the prosperity of which is near to my heart, and has ever been the object of my warmest wishes. " May the Almighty God, without the invocation of whom no action of importance should be begun, bless this undertak- ing, and enable us to carry it on with success : may He con- tinue to protect our University, the object of whose insti- tutions is to instil into the minds of youth principles of sound knowledge, to inspire them with the love of religion and virtue, and to prepare them for filling the various stations in society with honour to themselves, and with benefit to their country. All this we ask in the name of Christ ; and unto the Father, the Son, and the Holy Spirit, we ascribe the kingdom, power, and glory. — Amen." LETTER OF THE LATE PROFESSOR FERGUSON, THEN IN HIS NINETY- SECOND YEAR, TO THE LATE LORD ROBERTSON, ON THE SUBJECT OF HIS FATHER'S EPITAPH. " MY DEAR LORD, " St. Andrew's, Nov. 24th, 1814. " I have received your letter, enclosing the two copies of the inscription on your father's monument, one for Mr. Dempster, which I have delivered, and know his sense of your kind remembrance, as well as my own of the honour you have done me. In these acknowledgments I am afraid you will think me all too slow ; but this is now the mode of my existence, and ill qualified to change it. 320 ROBERTSON. " It has enabled me to communicate with some of the learned here, who join me in applauding the elegance and the appro- priate terms of that composition. " The authority of Dr. Gregory has no need of such sup- ports ; but I am fond to mention it. " I thought your father's birth and mine had been more nearly dated ; but I see that his preceded mine by two whole years, although I have survived so long to become my own monument — perishing you will say, but only more so, or less permanent, than some other grave-stones. I remember to have seen in Italy miles and leagues of ancient highways, strewed on right and left with continual vestiges of monu- ments, now destroyed or in ruins, with scarce a name to mark for whom they were intended ; but your father's memory is independent of any such materials. More fortunate than Tacitus or Livy, his works entire remain for ages indefinite, to show that in his time the British style in able hands was fit to emulate or cope with theirs. It were too much vanity for me to think the opportunity will then exist of giving judg- ment how little I had profited by the example which he set me, of literary talents and intellectual eminence. My way is now directed to the trackless grave, and there my course should terminate, but for the happy thought that there is somewhat after death to which this nursery and school of human life is no more than a preparation or a prelude. Meantime, however, I remain, with just esteem and gratitude for kind attentions, " Your most obliged and most humble servant, "ADAM FERGUSON. " The Right Honourable Lord Robertson, Edinburgh." The translation, of which the following forms the first two pages of the Principal's MS., was made, as appears by the date January 21, 1742, when he was about twenty — he hav- ing been born 19th September, 1721. The whole is carefully and admirably executed, combining clearness with elegance. ROBERTSON. 321 The other translations which I have seen of the ( Meditations/ will bear no comparison with this ; Gataker's ( 1 692) in Latin seems the best, but it is not good. To give an example, take the first paragraph : TO xaXoyjOss- is rendered by the translation of 1 692 " to be gentle and meek ;" by Mr. Graves's, of 1 792, " vir- tuous disposition of mind." aopyojrov, by the former " to refrain from all anger and passion ;" by the latter ' ' habitual command of my temper." Robertson gives both together clearly and elegantly, " to be of a complaisant and dispassionate temper of mind." xaXo-yjQs* is a word only found in Antoninus. Ste- phanus renders it " qui pulcra indole — probus — honestus ;" the late editors of Passow, in their excellent work (Messrs. Liddell and Scott), have rendered it " well disposed :" Gataker (1692), lf moris candidi." Robertson's version seems prefer- able, though not widely different. In the second paragraph we have ai$w/j.w rendered, unhappily enough, by the edi- tion of 1692, " shamefacedness," as a^tpevtxov is " manly be- haviour ;" while Graves gives both prolixly " modesty and manly firmness on all occasions." In paragraph 16 we find Ttyxepov xat ^evsrixov oKjaXsvrajf, the first word of which the edition of 1692 gives as " meekness ;" the edition of 1792, " mild condescension," which is a fanciful version ; the Ox- ford Greek-Latin edition of 1704, (t mansuetudinem ;" and Robertson, " mild disposition."

"VI. By Diognetus I was taught not to amuse myself with empty, trifling studies, not to give credit to the marvellous stories related of wizards, enchanters, and the exorcising of daemons ; not to spend my time in the breeding of quails and such like trifles ; to endure it patiently when men speak freely of me, and to apply myself wholly to the study of philo- sophy. By his advice I heard Bacchius, Tyndarides, and Marcianus, and, when very young, employed myself in com- posing dialogues ; used a mean bed, covered only with a skin ; and in every other thing emulated the manners of the Grecian philosophers. " VII. To Rupheus I am indebted for my resolution of re- forming and watching over my own morals, and that I did not fall into an imitation of the pride of the Sophists ; that I did not write upon merely speculative points, or compose quaint and finical exhortations to virtue ; that my exercises were not calculated to strike the fancy, and to carry with them an air of importance and austerity; that I applied my- self neither to rhetoric nor poetry, nor studied any affected elegance in my expressions ; that I did not wear the stola while within doors, and shunned all extravagant pride in my dress. By him I was taught to write my letters in a sim- ple style, after the model of those he sent from Sinuessa ; to show myself of a placable disposition towards those who have injured and offended me, and ready to be reconciled to them whenever they desire to return to my favour ; to read with accuracy, not to be content with a superficial consideration of things, and not rashly to give ear to great talkers. To him, likewise, I owe my acquaintance with the Commentaries of Epictetus, which he furnished me with. ROBERTSON. 323 " VIII. From Apollonius I learned to be at the same time free, and yet without any fluctuating uncertainty in my reso- lutions ; to have a regard to nothing beside reason, even in things of the smallest moment ; to preserve an equal mind under the most acute pain, upon the death of a child, and during the most lingering diseases ; and by a living example in himself, he showed me that it was possible for the same person to be upon occasion rigid or humane ; that we should instruct others with mildness and gentleness, and look upon our erudition and dexterity in delivering speculative truths as among the meanest of qualifications. By him also I was taught in what manner to receive presents from my friends, so as neither to appear too highly indebted to their favour, nor yet to dismiss them with cold indifference." Y 2 ( 324 ) B L A C 1C, THE physical sciences have few more illustrious names to boast than that of Joseph Black. With all the habits and the disciplined faculties of a true philoso- pher, with the temper as well as the capacity of a sage, he possessed that happy union of strong but disciplined imagination, powers of close undivided attention, and ample resources of reasoning, which forms original genius in scientific pursuits ; arid, as all these qualities may be combined in an individual without his happening to signalise his investigations of nature by any discovery, we must add that his life was crowned with the good fortune of opening to mankind new paths in which both himself and his followers successfully trod, enlarging to an incalculable extent the bounds of human knowledge. The modesty of his nature making him averse to publish his specu- lations, and the genuine devotion to the investigation of truth, for its own sake, rendering him most open in his communications with all who were engaged in the same pursuits, his incontestable claim to be regarded as the founder of modern chemistry has been oftentimes overlooked ; and, while some have endeavoured more or less obscurely to mingle themselves with his dis- coveries, others have thought it becoming to post-date BJLACSL /,•, BLACK. 325 the new system, that it might seem the produce of a somewhat later age. The interests of truth and justice therefore require that we should minutely examine the facts of the case ; and, happily, the evidence is so clear that it only requires an attentive consideration to remove all doubt from the subject. I feel it a duty imperatively cast upon me to undertake a task from which, did I not regard it as less difficult than sacred, I might shrink. But I had the great happiness of being taught by himself, having attended one of the last courses of lectures which he delivered ; and the knowledge thus gained cannot be turned to a better use than in recording the glory and in vindicating the fame of my illustrious master. The story of a philosopher's life is soon told. Black was born, in 1721, at Bordeaux, where his father, a native of Belfast, was settled as a merchant : he was, however, a Scotchman, and his wife too was of a Scot- tish family, that of Gordon of Hillhead, in Aberdeen- shire, settled like Mr. Black at Bordeaux. The latter was a person of extraordinary virtues, and a most amiable disposition. The celebrated Montesquieu honoured him with his especial regard ; and his son preserved, as titles of honour in his family, the many letters of the President to his parent. In one of them he laments the intended removal of the Black family as a thing he could not reconcile himself to, for his greatest plea- sure was seeing them often, and living himself in their society. Though Mr. Black sent his son, at the age of twelve, for some years to a school in Ireland, he was removed to the College of Glasgow in the year 1746, and ever after lived in that which was, properly 326 BLACK. speaking, his native country. At that college he studied under the celebrated Cullen, then Professor of Anatomy and Lecturer on Chemistry ; and, having removed in 1750 to Edinburgh for the benefit of that famous medical school, he took his degree there in 1754. In 1756 he was appointed to succeed Dr. Cullen in the chair of anatomy and chemistry at Glas- gow, and he continued to teach there for ten years, when he was appointed to the chemistry professorship at Edinburgh. He then lectured for thirty years to numerous classes, and retiring in 1796 lived till 1799, and died on the 26th of November in that year. His health never was robust ; it was indeed precarious at all times from a weakness in the bronchia and chest, but he prolonged life by a system of the strictest absti- nence, frequently subsisting for days together on water gruel and diluted milk. He never was married ; but he cherished with unvarying affection his near relatives, who well deserved his care. His favourite niece, Miss Burnet, a person of great sense and amiable temper, was married to his friend and second cousin, Professor Ferguson, the historian and moral philosopher. Dr. Black lived in a select circle of friends, the most illus- trious men of the times in science and in letters, Watt, Hutton, Hume, Robertson, Smith, and after- wards with the succeeding generation of Scottish worthies, Robison, Playfair, Stewart. Delighting to commune, to speculate, and to investigate with them, he was careless of the fame which however he could not but be sensible his labours must achieve. He was extremely averse to publication, contemning the im- patience with which so many men of science hurry BLACK. 327 to the press, often while their speculations are crude, and their inquiries not finished. Nor could the reason often urged in defence of this find much favour with one who seemed never to regard the being anticipated by his fellow-labourers as any very serious evil, so the progress of science was secured. Except two papers, one in the 'London Philosophical Transactions' for 1775 on the freezing of boiled water ; the other, in the second volume of the ( Edinburgh Transactions,' on the Iceland hot springs ; he never published any work after that of which we are now to speak, in 1755, and which, but for the accidental occasion that gave rise to it, would possibly, like his other original speculations, never have been given by himself to the press. Upon taking his degree at Edinburgh College he wrote and published a Latin Thesis, after the manner of that as well as the foreign universities. The subject was 'Magnesia, and the Acid produced by Food in the Stomach' (De Acido e Cibis orto ; et de Magnesia), and it contained the outline of his discoveries already made. Having sent some copies of this Thesis to his father at Bordeaux, one was given to Montesquieu, who at once saw the vast importance of the truths which it unfolded. He called a few days after and said to Mr. Black, " I rejoice with you, my very good friend : your son will be the honour of your name and of your family." But though the discoveries were sketched distinctly enough in this writing, they were only given at large the following year in his celebrated work, 'Experiments on Magnesia, Quicklime, and other Alkaline Substances,' incontestably the most 328 BLACK. beautiful example of strict inductive investigation since the ' Optics' of Sir Isaac Newton. His fervent ad- miration of that masterly work was indicated by his giving it to Professor Robison, then a student, and desiring him to " make it the model of all his studies," recommending him at the same time a careful study of the mathematics. It appears that this important inquiry concerning the alkaline earths, the results of which were destined to change the face of chemical science, was suggested by the attempts then making to find a solvent for the stone. I distinctly recollect Dr. Black, in his lectures, prefacing the admirable and most interesting account which he gave of his dis- coveries, with the statement that the hopes of finding a solvent which should not, like the caustic alkalies, destroy the substance of the bladder in melting the stone, first led him to this investigation. Professor Robison has given a note from his memorandum-book indicating that he had at first fallen into the notion of alkalies, when treated with quicklime, deriving from it their caustic quality; the common belief (which gave rise to the term caustic) being that lime obtained from the fire the quality of growing extremely hot, even to ignition when united with water. But expe- riment soon corrected this idea ; for, having exposed the caustic or quicklime to the air till it became mild, he says, " Nothing escapes (meaning no fire or heat) ; the cup rises considerably by absorbing air." Another observation on the comparative loss of weight sustained by chalk when calcined (in the fire), and when dis- solved in an acid, is followed by the account of a medical case, which the Professor knew to have BLACK. 329 occurred in 1752. A third note follows, and proves him to have now become possessed of the true theory of causticity, namely, the expulsion of air, and of mildness, namely, its absorption. The discovery was therefore made as early as 1752 — it was published generally in 1754 — it was given in its fullest details in 1755. At this time M. Lavoisier was a boy at school — nine years old when the discovery was made — eleven when it was published — twelve when it was as fully given to the world as its author ever delivered it. No pos- sibility therefore existed of that great man finding out when he composed his great work that it was a discovery of his own, as he did not scruple to describe oxygen, though Dr. Priestley had first communicated it to him in the year 1774 ; or that Black and he dis- covered it about the same time, as he was in the habit of stating with respect to other gases, with a con- venient degree of ambiguity just sufficient for self- defence, should he be charged with unfair appropriation. Who that reflects on the noble part which this great philosopher acted, both in his life and in his death, can avoid lamenting that he did not rest satisfied with the fame really his due, of applying the discoveries of others, in which he had no kind of share, to the investigation of scientific truths, as entirely the result of his extraordinary faculty of generalization, and genius for philosophical research, as those discoveries, the mate- rials of his induction, were the undivided property of others ! The capital discovery of Black, thus early made, and to any share in which no one has ever pretended, was that the causticity, as it was formerly termed upon a 330 BLACK. false theory, of the alkalis and alkaline earths, was owing to the loss of a substance with which they had been combined, and that their reunion with this sub- stance again rendered them mild. But the nature of this substance was likewise ascertained by him, and its detection forms by far the most important part of the discovery, for it laid the foundation of chemical science. He found that it was a permanently elastic fluid, like air in some of its mechanical qualities, those of being transparent or invisible, and incondensable, but differ- ing entirely from the air of our atmosphere in its chemical properties. It was separated from alkaline substances by heat, and by the application of acids, which, having a stronger elective affinity for them, caused it to be precipitated, or to escape in the aeriform state ; it was heavier than common air, and it gave a slight acidulous flavour to water on being absorbed by it; hence the inference that it was an acid itself. A short time afterwards (in 1757) he discovered that this peculiar air is the same with that produced by the fermentation of vegetable substances. This he ascertained by the simple experiment of partially emptying in a brewer's vat, where the fermenting process was going on, the contents of a phial filled with lime-water. On shaking the liquid that remained with the air that had entered, he found it become turbid, from the lime having entered into union with the air, and become chalk. The same day he discovered by an experiment, equally simple and equally decisive, that the air which comes from burning charcoal is of the same kind. He fixed a piece of charcoal in the broad end of a bellows nozzle, unscrewed ; and putting that in the fire, he inserted BLACK. 331 the other end in a vessel filled with lime-water. The air that was driven through the liquid again pre- cipitated the lime in the form of chalk. Finally, he ascertained by breathing through a syphon filled with lime-water, and finding the lime again precipitated, that animals, by breathing, evolve air of this description. The great step was now made, therefore, that the air of the atmosphere is not the only permanently elastic body, but that others exist, having perfectly different qualities from the atmospheric air, and capa- ble of losing their elasticity by entering into chemi- cal union with solid or with liquid substances, from which being afterwards separated, they regain the elastic or aeriform state. He gave to this body the name of fixed air, to denote only that it was found fixed in bodies, as well as elastic and separate. He used the term " air" only to denote its mechanical re- semblance to the atmospheric air, and not at all to imply that it was of the same nature. No one ever could confound the two substances together ; and ac- cordingly M. Morveau, in explaining some years after- wards the reluctance of chemists to adopt the new theory of causticity, gives as their excuse, that although this doctrine " admirably tallies with all the pheno- mena, yet it ascribes to fixed air properties which really make it a new body or existence" (" forment reellement un nouvel etre").* In order to estimate the importance of this dis- covery, and at the same time to show how entirely it * Supplement to the * Encyclopedic,' vol. ii. p. 274, published in 1777. 332 BLACK. altered the whole face of chemical science, and how completely the doctrine was original, we must now examine the state of knowledge which philosophers had previously attained upon the subject. It has often been remarked that no great discovery was ever made at once, except perhaps that of logarithms ; all have been preceded by steps which conducted the dis- coverer's predecessors nearly, though not quite, to the same point. Some may possibly think that Black's dis- covery of fixed air affords no second exception to this rule ; for it is said that Van Helmont, who flourished at the end of the sixteenth and beginning of the seven- teenth century, had observed its evolution during fer- mentation, and given it the name of gas silvestre, spirit from wood, remarking that it caused the phenomena of the Grotto del Cane, near Naples. But though he as well as others had observed an aeriform substance to be evolved in fermentation and in effervescence, there is no reason for affirming that they considered it as differing from atmospheric air, except by having absorbed, or become mixed with, certain impurities. Accordingly, a century later than Van Helmont, Hales, who made more experiments on air than any other of the old chemists, adopts the commonly received opinion that all elastic fluids were only different combinations of the atmospheric air with various exhalations or impurities ;* and this was the universal belief upon the subject, both of philosophers and of the vulgar. * It may safely be affirmed that Van Helmont's observation, which lay for a century and a half barren, threw no light of any value upon the subject. No one questions Newton's title to the discovery of the different refrangibility of light, and the true theory BLACK. 333 It is now fit that we see in what manner the subject was treated by scientific men at the period immediately preceding Black's discoveries. The article ' Air' in the French 'Encyclopedic' was published in 1751, and written by D'Alembert himself. It is, as might be expected, able, clear, elaborate. He assumes the sub- stance of the atmosphere to be alone entitled to the name of air, and to be the foundation of all other per- manently elastic bodies : " L/air elementaire, ou 1'air proprement dit," he says. He describes it as " homo- gene/' and terms it "1'ingredient fondamental de tout 1'air de 1'atmosphere, et qui lui donne son nom." Other substances or exhalations mix with it, he says, but these he terms " passageres," passing vapours, and not permanent : the air alone (that is, the atmo- spheric air) he calls " permanent," or permanently elastic (vol. i. p. 225). So little attention had the ob- servation of Van Helmont respecting the Grotto del of the rainbow; yet at the beginning of the 17th century, Antonio de Dominis, Archbishop of Spalatro, had really made an ingenious and well-grounded experiment on the similarity of the rainbow colours with those formed by the sun's rays refracted twice and reflected once in a globe filled with water. The doctrine of universal gravitation was known to both Kepler and Galileo ; arid Boulland (Astronomia Philolaica, lib. i., 1645) distinctly stated his belief or conjecture that it acted inversely as the squares of the distances. The famous proposition of equal areas in equal times was known to Kepler. The nearest approach to the Fluxional Calculus had been made by Harriott and Roberval and Fermat ; and to take but one other ex- ample, the electrical explosion of the Leyden jar, discovered in 1747, obtained the name of the coup-foudroyant, and was by Abbe Nollet conjectured to be identical with lightning, Franklin's celebrated experiment being only made in 1752. 334 BLACK. Cane excited, that we find a conjecture hazarded in the article ' Grotte' (vol. vii. p. 968), which appeared in 1756, — "peut-etre respirent ils (les chiens), ail lieu d'air, des vapeurs minerales ;" but this was some time after Black's discovery had taught us to distinguish such permanently elastic vapours from atmospheric air. In the article ' Fermentation' (vol. vi. p. 523) we find Van Helmont's doctrines of the connexion between fermentation and digestion treated with ridicule, and those who adopted them jocularly called the " fermen- tateurs." A few years later, however, the face of things changed. In the ' Supplement,' published in 1776, we find an article on ' Fixed Air/ and a reference to Dr. Black's discovery ; but nothing can be more indistinct than the author, M. Morveau's, ideas respecting it; for he leaves us in doubt whether it be the atmospheric air or a separate substance, and yet he states that the phenomena of fermentation and putrefaction are ex- plained by the evolution or absorption of this air, and that mineral waters derive from its presence their fla- vour. An abstract of M. Venel's book had in 1765, under the head of ' Mineral Waters,' given this explana- tion ; but instead of representing the air combined with the water as a different substance, he calls it " veritable air et meme tres pure." We have, however, seen that, in the following year (1777), M. Morveau's ideas were perfectly distinct on the subject ; for he treats it as a new substance, wholly different from atmospheric air. The slowness with which Black's doctrine made its way in France may be presumed from Morveau's re- mark on causticity, already cited, and also from this, BLACK. 335 that the article on 'Magnesia,' published in 1765, dog- matically asserts Black to be in error when he de- scribes Epsom salts as yielding that earth, " because," says the author, " those salts are purely Seidlitian," "entierement Seidlitiens" (vol. x. p. 858). In fact, Ep- som salts, magnesia, limestone, and sea-water are the great sources from which all magnesia is obtained. The first of these substances is in truth only a com- bination of magnesia with sulphuric acid. The other discoveries to which Black's led were as slowly disseminated as his own. Oxygen gas had been discovered, in August, 1774, by Priestley, and soon after by Scheele without any knowledge of Priestley's previous discovery ; yet in 1777 Morveau, who wrote the chemical articles in the ' Supplement,' never mentions that discovery, nor the almost equally important dis- covery of Scheele, chlorine, made in 1774, nor that of azote, discovered .by Rutherford in 1772, nor hydro- gen gas, the properties of which had been fully inves- tigated by Cavendish as early as 1766. Lavoisier's important doctrine, well entitled to be called a dis- covery, of the true nature of combustion, had likewise been published in 1774 in his ' Opuscules,' yet Mor- veau doggedly adheres to his own absurd theory of the air only being necessary to maintain those oscilla- tions in which he holds combustion to consist ; and finding that the increase of weight is always the result of calcination as well as combustion, he satisfies him- self with making a gratuitous addition to the hypo- thesis of phlogiston, and supposes that this imaginary substance is endowed with positive levity ; nor does he allude to the experiments of Lavoisier on gases, on 336 BLACK. combustion, and on oxidation, further than to say that he had for a considerable time been engaged in these inquiries. It was not indeed till 1 787 that he became a convert to the sound and rational doctrine, and abandoned the fanciful hypothesis, simple and inge- nious though it be, of Stahl. Berthollet, the earliest convert, had come over to the truth two years be- fore. Thus, discoveries had been made which laid the foundation of a new science, and on which the atten- tion of all philosophers was bent ; yet the greatest scientific work of the age made no more mention of them than if Black, Cavendish, Priestley, and Scheele had not been. The conjecture may be allowed to us, that if any of these great things had been done in France, M. Morveau would not have been suffered to preserve the same unbroken silence respecting them, even if his invincible prejudices in favour of the doc- trine of phlogiston had disposed him to a course so unworthy of a philosopher. The detail into which I have entered, sufficiently proves that the discovery of fixed air laid at once the foundation of the great events in the chemical world to which reference has just been made, because the step was of incalculable importance by which we are led to the fact that atmospheric air is only one of a class of permanently elastic fluids. When D'Alem- bert wrote the article ' Air,' in 1751, he gave the doc- trine then universally received, that all the other kinds of air were only impure atmospheric air, and that this fluid alone was permanently elastic, all other vapours being only, like steam, temporarily aeriform. Once the truth was made known that there are other gases BLACK. 337 in nature, only careful observation was required to find them out. Inflammable air was the next which became the subject of examination, because, though it had long been known, before Black's discovery it had been supposed only to be common air mixed with unc- tuous particles. His discovery at once showed that it was, like fixed air, a separate aeriform fluid, wholly distinct from the air of the atmosphere. The other gases were discovered somewhat later. But it is a very great mistake to suppose that none of these were known to Black, or that he supposed fixed air to be the only gas different from the atmospheric. The nature of hydrogen gas was perfectly known to him, and both its qualities of being inflammable and of being so much lighter than atmospheric air; for as early as 1766 he invented the air balloon, showing a party of his friends the ascent of a bladder filled with inflammable air. Mr. Cavendish only more precisely ascertained its specific gravity, and showed what Black could not have been ignorant of, that it is the same, from what- ever substance it is obtained. But great as was the discovery of fixed air, and important as were its consequences, the world was indebted to its illustrious author for another scarcely less remarkable, both from being so unexpected, and from producing such lasting effects upon physical science. About the year 1763 he meditated closely upon the fact, that on the melting of ice more heat seems to disappear than the thermometer indicates, and also that on the condensation of steam an unexpected pro- portion of heat becomes perceptible. An observation of Fahrenheit, on the cooling of water below the tern- 338 BLACK. perature of ice until it is disturbed, when it gives out heat and freezes at once, appears also to have attracted his careful consideration. He contrived a set of simple but decisive experiments to investigate the cause of these appearances, and was led to the discovery of latent heat, or the absorption of heat upon bodies passing from the solid to the fluid state, and from the fluid to the aeriform, the heat having no effect on surrounding bodies, and being therefore insensible to the hand or to the thermometer, and only by its absorption maintaining the body in the state which it has assumed, and which it retains until, the absorbed heat being given out, and becoming again sensible, the state of the body is changed back again from fluid to solid, from aeriform to fluid. He never published any account of this discovery, but he explained it fully in his Lectures, both at Glasgow and Edinburgh, and he referred to it in the paper already mentioned, which was printed in the < Philosophical Transactions * for 1775. Well, then, may we marvel that no mention whatever of latent heat is made in the celebrated * Ency- clopedic,' which owed its chemical contributions to no less a writer and experimentalist than Morveau. The doctrine of latent heat, however, was immediately applied by all philosophers to the production of the different airs which were successively discovered. They were found to owe their permanently elastic state to the heat absorbed in their production from solid or fluid substances, and to regain their fluid or solid state by combining either together or with those sub- stances, and in the act of union giving out in a sensible form the heat which, while absorbed and BLACK. 339 latent, had kept them in the state of elastic and in- visible fluids.* The third great discovery of Black was that which has since been called the doctrine of specific heat, but which he called the capacity of bodies for heat. Dif- ferent bodies contain different quantities of heat in the same bulk or weight ; and different quantities of heat are required to raise different bodies to the same sen- sible temperature. Thus, by Black's experiment, it was found that a pound of gold being heated to 150°, and added to a pound of water at 50°, the temperature of both became not 100°, the mean between the two, but 55°, the gold losing 95°, and the water gaining 5°, because the capacity of water for heat is nineteen times that of gold. So twice as much heat is required to raise water to any given point of sensible heat as to raise mercury, the volumes of the two fluids compared being equal. The true doctrine of combustion, calcination of metals, and respiration of animals, which Lavoisier deduced from the experiments of Priestley and Scheele upon oxygen gas, and of Cavendish on hydrogen gas, and which has changed the whole aspect of chemical science, was founded mainly upon the doctrines of latent and specific heat. It was thus the singular felicity of Black to have furnished both the pillars upon which modern chemistry reposes, and to have * It is by no means impossible that one day we may be able to reduce the phenomenon of light within the theory of latent heat. It may be that this body when absorbed, that is, fixed in substances, gives out heat ; as, while passing through diaphanous substances and remaining unfixed, its heat is not sensible. z 2 340 BLACK. furnished them so long before any one attempted to erect the superstructure, that no doubt could by any possibility arise respecting the source of our increased knowledge, the quarter to which our gratitude should be directed. Fixed air was discovered in 1752, and fully explained to the world in 1754 and 1755. Latent heat was yearly, from 1763, explained to nu- merous classes of students, before whom the experi- ments that prove it were performed by the author's own hands. Cavendish made his experiments on in- flammable air in 1766 ; Priestley began his in 1768, first publishing in 1 772 ; and he discovered oxygen in 1774, in which year the nature of combustion was first explained by Lavoisier, a boy at school when fixed air was discovered, and having made no experiments nor written any one line upon chemical subjects for seven years after latent heat was discovered. But we shall form a more striking idea to ourselves of the revolution which Black thus effected in che- mistry, if we attend a little to the state of that science in general before he began his labours, We have already seen the low condition of the knowledge then possessed respecting aeriform fluids ; the general con- dition of the science was in the same proportion humble. The celebrated ' Preliminary Discourse' to the ' En- cyclopedic' makes hardly any mention of chemistry among the sciences; and in the ' Arbre Encyclopedique,' on which the authors (D'Alembert and Diderot) plume themselves much, we find it not very distinctly repre- sented, or in very good company. It is termed the science of interior and occult qualities of bodies, its BLACK. 341 objects being to imitate and rival nature, by decom- posing, reviving, and transferring substances. It is represented as holding among the sciences the place which poetry occupies among other branches of litera- ture. Its fruits are said to be alchemy, metallurgy, natural magic, and chemistry properly so called, which is stated to consist of pyrotechny and dyeing. Strange to tell, pharmacy is not given as one of its fruits, being referred wholly to the branch of medical science. But the state of chemistry is better understood by the article itself in the ' Encyclopedic/ the elaborate work of M. Venel of Montpelier, well known for his researches concerning mineral springs, and author of most of the chemical articles in the original work, as M. Morveau was of those in the ' Supplement/ and whose mistakes on the subject of magnesia, aris- ing from prejudice, have already been mentioned. This article begins with lamenting the lo\v condition of his favourite science : " Elle est peu cultivee parmi nous. Cette science n'est que tres mediocrement repandue, meme parmi les savans, malgre la pretention a 1'uni- versalite des connaissances qui font aujourd'hui le gout dominant. Les chimistes forment un peuple distinct, tres-peu nombreux, ayant sa langue, ses mysteres, ses loix, et vivent presque isoles au milieu d'un grand peuple peu curieux de sa connaissance, n'entendant presque rien de son industrie." He then goes on to show that this " incuriosite, soit reelle, soit simulee," is yet extremely unphilosophical, inasmuch as it leads to a rash condemnation ; and that those who know any subject superficially may possibly be deceived in their 342 BLACK. own judgment upon it, " the consequence of which has been," he adds, "that owing to the prejudices enter- tained against the nature and reach of the science, it becomes a matter of no small difficulty or slight con- troversy to say clearly and precisely what chemistry is. Some make no distinction between the chemist and the quack who seeks after the philosopher's stone (souffleur) ; others think any one a chemist who has a still for preparing perfumes or colours. Many con- sider the compounding of drugs as containing the whole of the art. Even men of science know scarcely any thing about the chemists." — " What natural phi- losopher," he asks, " so much as ever names Becker or Stahl? Whereas those who, having other scientific illustrations, as John Bernouilli and Boerhaave, have written chemical works, or rather works on chemical subjects, are very differently thought of; so that the for- mer's work on ' Fermentation,' and the latter's on 'Fire,' are known, cited, and praised, while the far greater views of Stahl on the same subjects only exist for a few chemists." He then goes on to cite other proofs of the low estimate formed of the science, and even the pre- vailing impression of chemists being mere workmen ; and concludes, that " the revolution which should raise chemistry to the rank it merits, and place it on a level with natural philosophy, can only be accomplished by a great, an enthusiastic, and a bold genius." While waiting for the advent of this new Paracelsus, he says, it must be his task to present chemistry in a light which may show it worthy the notice of philosophers, and capable of becoming something in their hands. If we go back to an earlier period, we shall find BLACK. 343 that Lord Bacon, although he quite clearly perceived that chemistry might one day be advanced to the rank of a science (De Dig. et Aug. iii.), yet always treats the chemistry of his day as merely empirical (Nov. Org. s. Ixiv. Ixxiii.*). But I have preferred taking the account of chemical science from the ' Encyclopedic/ first, because it gives, if not the opinion or the testi- mony of the learned body at large who prepared that work, yet certainly an opinion and a testimony which had the sanction of its more eminent members ; and, secondly, because its date is at the eve of the great revolution in natural science of which we are speaking. * " Itaque talis philosophia (in paucorum experimentorum ar- gutiis et obscuritate fundata) illis qui in hujusmodi experimentis quotidie versantur atque ex ipsis phantasmatis contaminarunt, pro- babilis videtur, et quasi certa ; caeteris incredibilis et vana, cujus exemplar notabile est in chemicis eorumque dogmatibus." It must be added that beside the injustice here done to Van Hel- mont, he goes on to rank Gilbert in the same empirical class, as he elsewhere does — a most incorrect view of Gilbert's induction, the most perfect by far of any before Lord Bacon's age, and, though mixed with some hypothetical reasoning, hardly in strictness ex- celled by any philosopher of after times. I cannot come so near the remarkable sixty-fifth section of the c Novum Organum' without digressing so far from my subject as to cite the prophetic warning given to some zealots without knowledge of our own times against the " apotheosis errorum," the " pestis intellectus, si vanis accedat veneratio." " Huic autem vanitati (adds the pious and truly Chris- tian sage) nonnulli ex modernis summa levitate ita indulserunt ut in primo capitulo Geneseos et in libro Job et aliis scriptures locis phi- losophiam naturalem fundari conati sunt ; inter mortua quserentes viva ;" a folly the more to be deprecated, he says, because " ex divinarum et humanarum malesana admistione non solum educitur philosophia phantastica, sed etiam religio haeretica." His practical conclusion, therefore, is to render unto faith the things alone which are faith's : " Admodum salutare, si mente sobria, fidei tantum dentur quse fidei sunt." 344 BLACK. The last passage which has been cited from that worK strikingly illustrates the low ebb at which chemical science then was. — It is certain that after the discoveries of Black had opened vast and new views of nature, both as regards the operations of heat, the most powerful and universal of all agents, and as regards the constitution of elastic fluids, the most unknown of the four elements, no natural philo- sopher would have had the hardihood to doubt if che- mistry was an important branch of his science, and no chemist would have performed the superfluous task of vindicating its claim to the title. We have now gone through the whole of this in- teresting subject, rather occupied in contemplating the foundations of a new science than in tracing the exten- sion of the boundaries which confine an old one. The universal operation of heat, and the agency which it exerts by its absorption and its evolution on the struc- ture of all bodies, renders the discovery of its nature and action in these respects, next to that of gravitation, the most important step which has been made in the progress of physical science. The new field opened to philosophical inquiry by the discovery of the gaseous bodies is only second to the former step in the import- ance of its consequences. It is as objects of pure science, the mere contemplation of scientific truth, that we have been considering these great discoveries ; yet they have amply contributed also to the advance- ment of the arts. The illustrious improver of the steam engine was too young to have joined in the experiments on fixed air ; but in the course of those by which latent heat was discovered, he had a constant and confidential BLACK. 345 intercourse with Black, one of his earliest patrons ; and although it is as certain that he did not owe to that philosopher's suggestions any of the steps by which his inventions were compassed, as it is that he had him- self no share in Black's great discovery, it cannot be doubted that the knowledge thus acquired of the true nature of heat, of steam, of evaporation, and of con- densation, contributed most essentially to his mighty improvements. As for the gases, it would be difficult to name the branch of art which has not in some manner and to some extent gained by their discovery. So that the great man whose history we are contem- plating, had the satisfaction of seeing the triumphs of his youth bear fruit in every direction, exalting the power and increasing the comforts of mankind as well as extending the bounds of their knowledge and enlarg- ing the range of their industry. He was but twenty- four years old when he made his first discovery, and thirty-four when his second was added. He lived to nearly fourscore. It remains to consider him as a teacher ; and cer- tainly nothing could be more admirable than the manner in which for forty years he performed this use- ful and dignified office. His style of lecturing was as nearly perfect as can well be conceived ; for it had all the simplicity which is so entirely suited to scientific discourse, while it partook largely of the elegance which characterized all he said or did. The publica- tion of his lectures has conveyed an accurate idea of the purely analytical order in which he deemed it best to handle the subject with a view to instruction, consider- ing this as most likely to draw and to fix the learner's 346 BLACK. attention, to impress his memory, and to show him both the connexion of the theory with the facts, and the steps by which the principles were originally ascer- tained. The scheme of the lectures may thence be ap- prehended— the execution imperfectly ; for the diction was evidently, in many instances, extemporaneous, the notes before the teacher furnishing him with little more than the substance, especially of those portions which were connected with experiments. But still less can the reader rise from the perusal to any con- ception of the manner. Nothing could be more suited to the occasion ; it was perfect philosophical calmness ; there was no effort ; it was an easy and a graceful conversation. The voice was low, but per- fectly distinct and audible through the whole of a large hall crowded in every part with mutely attentive lis- teners ; it was never forced at all any more than were the motions of the hands, but it was anything rather than monotonous. Perfect elegance as well as repose was the phrase by which every hearer and spectator naturally,, and as if by common consent, described the whole de- livery. The accidental circumstance of the great teacher's aspect, I hope I may be pardoned for stopping to note, while endeavouring to convey the idea of a phi- losophic discoverer. His features were singularly grace- ful, full of intelligence, but calm as suited his manner and his speech. His high forehead and sharp temples were slightly covered, when I knew him, with hair of a snow-white hue, and his mouth gave a kindly as well as most intelligent expression to his whole features. In one department of his lecture he exceeded any I have ever known, the neatness and unvarying success with BLACK. 347 which all the manipulations of his experiments were performed. His correct eye and steady hand contri- buted to the one ; his admirable precautions, foreseeing and providing for every emergency, secured the other. I have seen him pour boiling water or boiling acid from a vessel that had no spout into a tube, holding it at such a distance as made the stream's diameter small, and so vertical that not a drop was spilt. While he poured he would mention this adaptation of the height to the diameter as a necessary condition of success. I have seen him mix two substances in a receiver into which a gas, as chlorine, had been introduced, the effect of the combustion being perhaps to produce a com- pound inflammable in its nascent state, and the mixture being effected by drawing some string or wire working through the receiver's sides in an air-tight socket. The long table on which the different processes had been carried on was as clean at the end of the lecture as it had been before the apparatus was planted upon it. Not a drop of liquid, not a grain of dust remained. The reader who has known the pleasures of science will forgive me if at the distance of half a century I love to linger over these recollections, and to dwell on the delight which I well remember thrilled me as we heard this illustrious sage detail, after the manner I have feebly attempted to pourtfay, the steps by which he made his discoveries, illustrating them with anecdotes sometimes recalled to his mind by the passages of the moment, and giving their de- monstration by performing before us the many expe- riments which had revealed to him first the most important secrets of nature. Next to the delight of 348 BLACK. having actually stood by him when his victory was gained, we found the exquisite gratification of hear- ing him simply, most gracefully, in the most calm spirit of philosophy, with the most perfect modesty, recount his difficulties, and how they were overcome ; open to us the steps by which he had successfully ad- vanced from one part to another of his brilliant course ; go over the same ground, as it were, in our presence which he had for the first time trod so many long years before ; hold up perhaps the very instruments he had then used, and act over again the same part before our eyes which had laid the deep and broad foundations of his imperishable renown. Not a little of this extreme interest certainly belonged to the accident that he had so long survived the period of his success — that we knew there sat in our presence the man now in his old age reposing under the laurels won in his early youth. But take it altogether, the effect was such as cannot well be conceived. I have heard the greatest under- standings of the age giving forth their efforts in its most eloquent tongues — have heard the commanding periods of Pitt's majestic oratory — the vehemence of Fox's burning declamation — have followed the close- compacted chain of Grant's pure reasoning — been carried away by the mingled fancy, epigram, and argumentation of Plunket; but I should without hesitation prefer, for mere intellectual gratification (though aware how much of it is derived from asso- ciation), to be once more allowed the privilege which I in those days enjoyed of being present while the first philosopher of his age was the historian of his own discoveries, and be an eye-witness of those experiments BLACK. 349 by which he had formerly made them, once more per- formed with his own hands. The qualities which distinguished him as an inquirer and as a teacher followed him into all the ordinary affairs of life. He was a person whose opinions on every subject were marked by calmness and sagacity, wholly free from both passion and prejudice, while affectation was only known to him from the comedies he might have read. His temper in all the circumstances of life was unruffled. This was perceived in his lectures when he had occasion to mention any narrow prejudice or any unworthy proceeding of other philosophers. One ex- ception there certainly was, possibly the only one in his life ; he seemed to have felt hurt at the objections urged by a German chemist called Meyer to his doctrine of causticity, which that person explained by supposing an acid, called by him acidum pingue, to be the cause of alkaline mildness. The unsparing severity of the lecture in which Black exposed the ig- norance and dogmatism of this foolish reasoner cannot well be forgotten by his hearers, who both wondered that so ill-matched an antagonist should have succeeded where so many crosses had failed in discomposing the sage, and observed how well fitted he was, should occasion be offered, for a kind of exertion exceedingly different from all the efforts that at other times he was wont to make. The soundness of his judgment on all matters, whether of literature or of a more ordinary description, was described by Adam Smith, who said, he "had less nonsense in his head than any man living/* The elegance of his taste, which has been observed upon as 350 BLACK. shown in his lectures, was also seen in the efforts of his pencil, which Professor Robison compares to that of Woollett. The neatness of his manipulations was not confined to his experiments when investigating or when lecturing. I have heard one who happened to see him at his toilette describe the operations as per- formed with exquisite neatness by a number of contrivances happily adapted to the saving of trouble and avoiding uneasiness. His perfect equanimity has been adverted to, and it did not proceed from coldness of disposition, for he was affectionately attached to his friends. Having no family of his own, he may be said to have fallen into those precise and regular habits which sometimes raise, in happier individuals a smile, I stop not to inquire whether of envy or contempt, for the single state. It was sometimes said, too, that his habits were penurious. That the expenses of one who had no love of pleasure and no fancy for ostentation to gratify, must have been moderate, is certain ; but he lived in the style and manner suited t© one possessing an ample income. The ground of the charge was, I believe, that he was said to have a scale by him when he received the fees of his students. I can answer for the truth of this statement, for I well remember the small brass instrument ; but I also recollect that he said it became necessary from the quantity of light gold which he used at first to receive unsuspected from one class, particularly, of his pupils. There was certainly no reason why he should pay a sum of forty or fifty pounds yearly out of his income on this account. Both Professor Ferguson and Professor Robison have positively denied the charge of avarice, and have given BLACK. 351 ample testimony even to his generous nature. While he lived at Glasgow he lost three-fourths of his fortune by the failure of a house in which it was invested ; and though he had foreseen the catastrophe for two years, he neither attempted to withdraw his funds, nor altered in any respect his kind demeanour towards the head of the firm, whom he knew. At Edinburgh he more than once incurred great risks to help friends in business. The gradual decay of his strength brought about the extinction of life without pain and without any discom- posure. Professor Robison told me that he was sure nothing could be more agreeable to his illustrious friend's wishes than this end, as nothing was more likely to vex and annoy him than the unavoidable ac- companiments of a protracted illness and a sick-bed. He often indeed expressed a wish that he might be spared this suffering, and that wish was fully gratified. It seemed, said the Professor, as if he waited calmly until the last stroke of his pulse should be given. It is cer- tain that he passed from this life so quietly as not to spill a cup of milk and water (a customary dinner with him) which he at the moment was holding in his hand, and which rested on his knee. His attendants saw him in this posture, and left the room supposing him still alive. On returning soon after they saw him exactly sitting as before, and found that he had expired. ( 352 ) WATT. THE intimacy of Mr. Watt with Dr. Black from his earliest years has been already mentioned. When the latter was a Professor at the University of Glasgow, Watt, then a young man, was employed as mathe- matical instrument maker to the Natural Philosophy class, and was in daily communication with the Pro- fessor while his experiments on heat, evaporation, and condensation were carried on. I well remember him afterwards, in his lectures at Edinburgh, mentioning that his young coadjutor employed himself at the same time in researches upon the nature of steam ; and it is certain that his subsequent inventions were greatly aided by the discoveries of Black respecting heat. To the inquiries out of which these inventions arose, he appears to have been led by the accident of having a model of an engine to repair for the Professor of Natural Philosophy. But, before examining the foundations upon which his great and well-earned fame rests, it is fit that we should first consider the state in which he found the engine, which he almost created anew. This is following the same course which has been pursued with respect to the discoveries of Dr. Black.

The ancients accordingly were so far acquainted with it as to have constructed an instrument, the seolipile, composed of a metallic ball, which, having some water in its bottom, was placed in the fire, and the steam, issuing through a small orifice or tube with great force, could, they con- ceived, blow a fire or even turn the vanes of a mill. No use, however, seems ever to have been made of this philo- sophical toy ; nor does any attention appear to have been paid to steam, as an agent, until 1615, when Salomon de Caus, a French engineer, published a work on ' Moving Forces/ in which he describes a method of raising water by partially heating it, that is, converting a portion of it into steam, and, by its expansive force, driving the rest of the fluid through the tube connected with the reser- voir or chamber.* In 1663 the Marquis of Worcester (known in our political history as Earl of Glamorgan, and as having been employed by Charles I. in 1646 to negotiate with the Irish Catholics) published his ' Century of the Names and Scantlings of Inventions/ of which Mr. Hume, in his ' History' (vol. vii., note o), has been pleased to say that it is "a ridiculous com- pound of lies, chimeras, and impossibilities, showing what might be expected from such a man/' The better * M. Arago is not entitled to complain of English writers for having " aimed at expunging every French name from this important chapter in the history of science." He says they at once gave up Lord Worcester's claims on discovering that Salomon de Caus had preceded him. Now both Mr. Farey and Mr. Stuart have done ample justice to Caus in their works on the steam engine. As for Lord Worcester, Mr. Stuart (whose history is far from accurate on this point) has both attacked and defended his claims in his several works. 2 A 354 WATT. opinion seems to be, that the historian had never read the book he thus describes ; but being anxious to relieve Charles I. from the blame of his Ambassador's negotiation, which proved the source of much outcry against the King, he states the low opinion which the latter entertained of Worcester's judgment as a proof that he never would authorise him to act in so delicate a matter as religious concessions without the privity of the Lord- Lieutenant, and he is very ready to strengthen this view by showing that the opinion was well founded. Be this, however, as it may, the ignorance and error is all on Hume's side, for the work is highly creditable to its author's learning and ingenuity, and it un- doubtedly contains a proof that he had made one step in advance of Caus towards the use of steam-power. His Sixty-eighth Invention is entitled " an admirable and most forcible way to drive up water by fire." He describes his having made a " constant fountain stream of water, raised in the proportion of forty times the quantity of that which he converted into steam ;" and he states that the height to which he raised it was forty feet, clearly showing that it was not on the principle of the sucking-pump, which can only raise water thirty-three feet. He expressly says that, while the atmospheric pressure by which the sucking-pump acts is limited in its operation, the force of steam which he employed " hath no other boundary than the strength of the vessel which contains it." Finally, he seems to have used a cannon as his boiler, which indicates his having tried the experiment on a large scale. The great doubt expressed by M. Arago whether or not Lord Worcester ever executed the design more or less WATT. 355 clearly described in his book appears to me to have no foundation. The inference arising from the descrip- tion seems to remove that doubt ; but we have external evidence more precise and satisfactory still.* The travels in England of the Grand Duke of Tuscany, Cosmo de' Medicis, were written by his Secretary, Magalotti, a man of some scientific eminence ; and a translation into English was published in 1821. The visit to London took place in the year 1 669 ; and it appears that the Grand Duke " went to see, at Vaux- hall, an engine or hydraulic machine invented by the Marquis of Worcester," and the account which he gives of it tallies with Lord Worcester's description of his " stupendous water-commanding engine." The account of Lord Worcester is far from being clear and distinct, and nothing appears to have resulted from his suggestions. In 1690, Papin, an eminent and able French engineer, settled in London, and author of the digester which goes under his name, pub- lished a work in which he showed that he had made two most important steps in the use of steam. Caus and Worcester had applied the force directly to the body which it was intended to move ; and it was evident that, while that was a condition of its use, very limited bounds must confine the operation. But Papin, observing the use of the piston in a com- mon sucking-pump, applied this to the steam machine, making it work in the cylinder, and be the medium of * See also the Marchioness of Worcester's correspondence with her Confessor, communicated by the Beaufort family to Mr. Par- tington for his edition of the < Century/ 2 A 2 356 WATT. communicating motion to other apparatus. Next, he applied steam directly as the agent, to raise the piston ; and making a vacuum by the condensation of the steam, he thus caused the atmosphere to press down the piston. Guericke, the inventor of the air-pump, had half a century earlier used the vacuum, made by his machine in the same manner, as a mechanical power, by the help of a piston and rod ;* and he invented the valve, without which the vacuum could not be produced. The application of the same principle and of the same contrivance to steam was Papin's ; and its importance, and his merit, are not diminished by considering the source from which he borrowed it.f Indeed the action of the air in the sucking-pump is another form of the same experiment. It must be added that to Papin also we owe the im- portant invention of the safety-valve, although he did not apply it to the steam engine. He introduced it as a part of his digester, but suggesting that it was appli- cable to the steam engine. It is, however, certain that the most rude and cum- brous part of the former invention was continued by Papin. The fire was applied to the water, and when it had filled the cylinder with steam, the condensation was only effected by withdrawing or extinguishing the fire. Savery about the year 1 698 made considerable * See the distinct figure in his plate xiv., p. 109, of l Experi- menta nova Magdeburgica de Vacuo Spatio.' Amstelodami, 1672. | Acta Eruditorum, 1688. The paper has an excellent and clear figure. Nothing can be more groundless than Mr. Stuart's statement that Baptista Porta had anticipated Papin in this impor- tant step. The passage refers only to the rise of water in a vacuum. See * I tre Libri dei Spiritali,' 1606. WATT. 357 improvements on the apparatus ; and though he did not use the vacuum as Papin had done, but only as it is used in the sucking-pump, he yet produced it by apply- ing cold water to the outside of the cylinder. The machines made by him were so manageable that they were brought into use for raising water in many country houses. D'Alesme exhibited a machine before 1705 (as appears by the ' Histoire de 1' Academic des Sciences' for that year, p. 1 37), in which water was made to spout to a great height by the force of steam alone. It is extremely doubtful if Papin ever erected any steam engine, either upon his own or upon any other principle. It is certain that he did not adhere to the two great propositions which he had brought forward, the operating by a piston, and the operating by the pressure of the atmosphere ; he recurred to the old plan of making the steam act directly upon the weight to be raised. In 1711 Newcomen, an iron-master of Dartmouth, and Galley, or Cawley, a glazier of the same town, constructed an engine upon Papin's principle of a piston and a condensing process, using, however, Savery's mode of creating a vacuum by cold affusion, for which they were led by an accident to substitute the method of throwing a jet or stream of cold water into the cylinder. This important improvement saved, in a considerable degree, the waste of heat occasioned by Savery's method of condensing. Their engine could be applied with advantage to raise water from mines, which Savery's was wholly incapable of effect- ing, its power being limited to that of the sucking- pump. Newcomen's engine, as it is generally called, made no use at all of the direct force of steam ; it 358 WAIT. worked entirely by means of the vacuum ; and hence it is sometimes and justly termed the atmospheric engine, as its moving force is the pressure of the atmosphere. Desaguliers, who has given the best description of Newcomen and Cawley's engine, about the year 1717 or 1718 made several of those engines, in which he executed Papin's suggestion of using the safety- valve. In the same year Beighton perfected the me- chanism whereby the engine itself shut and opened the valves, by which the supply of steam to the cylinder and of water to the boiler is regulated ; and Smeaton subsequently made some other mechanical improve- ments. With these exceptions the steam engine con- tinued exactly in the same state from the time of New- comen to that of Watt, above half a century later. We have thus seen how very slowly this great invention was brought to the state in which Mr. Watt found it, and how considerable a number of persons con- tributed each a small share to its progress. Let us enu- merate these steps : they are at least six in number. S. de Caus made steam act to raise water ; Worcester per- formed this operation in a more regular and mechanical manner ; Papin used the condensation of steam, and through that the atmospheric pressure, as well as the direct expansive force, and he worked the engine by a piston ; Savery condensed by refrigeration instead of the mere absence of fire, but did not use the atmosphere ; Newcomen used the jet for condensing and the atmo- sphere for pressure, but did not use the direct force of steam ; Desaguliers introduced the safety-valve ; Beigh- ton and Smeaton improved the mechanism ; D'Alesme needs not be mentioned, as we are not informed what WATT. 359 plan he executed, but he certainly made no step himself. If the direct force of steam, as well as atmospheric pressure, had been both employed, with the jet of cold water, the safety-valve, and the contrivance for regu- lating the supply-valves, a far better engine than any ever known before the time of Watt would have been produced, and yet nothing whatever would have been added to the former inventions ; they would only have been combined together. The result of the whole is, that one of the greatest theoretical steps was made by Papin, who was, during a long period, little commemo- rated; and that Savery and Newcomen, who have been by many called the inventors, were the first of all the inge- nious and useful persons whose successive improvements we have now recorded, to apply the steam-engine to practical purposes. France has thus produced the man who, next to Watt, must be regarded as the author of the steam-engine : of all Watt's predecessors, Papin stands incontestably at the head ; but it is almost cer- tain that he never actually constructed an engine. Though the engine of Savery was of considerable use in pumping to a small height, and indeed has not entirely gone out of use even in our own times, and though Newcomen's was still more extensively useful from being applicable to mines, not only had no means ever been found of using the steam power for any other purpose than drawing up water, but even in that operation it was exceedingly imperfect and very expensive, insomuch that a water power was often preferred to it, and even a horse power in many cases afforded equal advantages. The great consumption of fuel which it required was its cardinal defect; the 360 WATT. other imperfection was its loss of all direct benefit from the expansive force of the steam itself. That element was only used in creating a vacuum, and an air-pump might have done as much had it been worked by water or by horses. It was, in the strictest sense of the word, an air and not a steam engine. When Mr. Watt was directed to repair the working model for the Professor at Glasgow, he of course exa- mined it attentively. He was at that time, 1763, in his twenty-eighth year, having been born in 1736 at Greenock, where his father was a magistrate, and had learnt the business of a mathematical instrument maker. He had been prevented by delicate health from benefiting much by school instruction ; but he had by himself studied both geometry and mechanics, hav- ing from his childhood shown a marked taste for those pursuits, in which his grandfather and uncle, teachers of the mathematics, had been engaged. It is related of him that a friend of his father's one day found the child stretched on the floor drawing with chalk nume- rous lines that intersected each other. He advised the sending the young idler, as he supposed him, to school, but the father said, " Perhaps you are mistaken ; exa- mine first what he is about." They found he was try- ing, at six years old, to solve a problem in geometry. So his natural turn for mechanics was not long in showing itself; and his father indulging it by putting tools in his hands, he soon constructed a small elec- trical machine, beside making many childish toys. He occasionally visited his mother's relations at Glasgow, but never attended any lectures there, or elsewhere. The ardour of his active mind was su- WATT. 361 perior to all the restraints which the weakness of his bodily frame could impose. He devoured every kind of learning. Not content with chemistry and natural philosophy, he studied anatomy, and was one day found carrying home for dissection the head of a child that had died of some hidden dis- order. His conversation, too, was so rich, so animated, that we find, from the relation of Mrs. Campbell, a female cousin of his, the complaints made by a lady with whom he resided. She spoke of the sleepless nights which he made her pass by engaging her in some discus- sion or some detail of facts, or some description of phe- nomena, till the night was far advanced towards morn- ing, and she found it impossible to tear herself away from his talk, or to sleep after he had thus excited her. In 1755 he placed himself with Mr. Morgan, mathematical and nautical instrument maker, of Cornhill, and resided with him somewhat less than a year, during which he was chiefly employed in the preparation and adjustment of sextants, compasses, and other nautical instruments. But the same fee- ble health which had interrupted his studies at Glasgow again oppressed him ; he was obliged to leave London, and return to Glasgow. On his arrival there he had the intention of setting up as an instrument maker, but the Glasgow Body of Arts and Trades, one of the sub- corporations in the muni- cipal corporation of that city, opposed him as not free of their craft or guild, and therefore not entitled to exercise his calling within the limits of the charter. Attempts were made to obtain their leave for a very small workshop, on the humblest scale, but this was 362 WAIT. peremptorily refused. The University therefore came to his assistance, granted him a room in their own building, and gave him the appointment of their mathematical instrument maker. There remain small instruments then made by him in this workshop, and executed entirely with his own hands ; they are of exquisite workmanship. The earliest of his steam- engine drawings are likewise preserved, and those competent judges who have examined them, particularly M. Arago, describe them as " truly remarkable for the neatness, the strength, and the accuracy of their outline." His manual dexterity and skill, therefore, is clear, and he had good cause to plume himself as he always did upon it, estimating the same quality in others at its just value. In the course of a very few years, beside renewing his intimacy with Mr. Robison, afterwards Professor there and at Edinburgh, he became intimately acquainted with the most eminent of the Glasgow Professors, Adam Smith, Robert Simson, Robert Dick, and above all, Dr. Black. Of these all but Mr. Dick have left the deep im- press of their great names upon the scientific history of their age ; and he was always described by both Mr. Watt and Professor Robison as a person of most admira- ble capacity and great attainments, treating natural philosophy, too, with singular ability and success, nor prevented from acquiring a more extensive and lasting reputation by anything save his premature death. While thus occupied and thus befriended by men of great names, his own reputation increased daily as a successful cultivator of natural science. His work- WATT. 363 shop became the resort of all zealous students and enlightened inquirers into physical science, and was particularly resorted to by the pupils of the University. Professor Robison tells us that though regarding himself as a proficient in the mixed mathematics and in experimental philosophy, he was somewhat mortified at finding Watt so greatly his superior in the same favourite departments of study. In truth, it was the ordinary practice to consult him as the oracle upon any difficulty coming in the way of either students or in- quirers. His fixed resolution to be deterred by no difficulties was constantly apparent, and one example is given by the Professor. The solution of a problem which occupied Watt and his friends, seemed to require the perusal of Leupold's Theatre of Machines, and as it was written in German, he at once learnt that language in order to consult the book. Another instance of his indomitable perseverance against great difficulties apparently irremovable, though not insuper- able, may be added. He had no ear at all for music : not only was he through life wholly insensible to its charms, but he could never distinguish one note from another; yet he undertook the construction of an organ ; and the instrument which he made not only had every mechanical merit from the most ingenious contrivances for conducting and regulating the blasts and the move- ments of the machine, but produced the most admirable harmonic results, so as to delight the best performers. He overcame the difficulties which lay in his way, partly by the phenomenon of the beats of imperfect consonances, a theory then little understood, and only contained in a work at once very profound and very 364 WAIT. obscure, Smith's ' Harmonics.' This treatise, of which only the first and less perfect edition was then pub- lished, must have been read and understood by the young engineer. While employed by Dr. Roebuck at his W6rks, he made a guitar for his daughter, after- wards Mrs. Stuart, which she still possesses, and relates the sum given for it to have been five guineas. It only remains to add that all the reading and all the speculations of Watt were strictly confined to hours which did not interfere with his profession or his trade of an instrument maker. The whole of the day was devoted to his business, only subject to the interruption of the discussions raised by those who frequented his workshop in search of assistance and information. It was late in the evening, or rather in the night, that he prose- cuted with zeal and close attention his philosophical studies ; for his principle through life was steadily kept in view, and uniformly acted on, never to let anything whatever interfere with business, the transaction of which he regarded as a primary duty to be performed, and entitled, as such, to take precedence of all other pursuits. There chanced to be among the apparatus of the Natural Philosophy class a model of Newcomen's steam-engine, which, from some defect in the construc- tion, never could be got to work well ; and Mr. Watt was desired to examine and report to the Professor, Mr. Anderson, successor of Dr. Dick, and better known afterwards as having founded by his will the class in which Dr. Birkbeck taught the working men, and thus gave rise to Mechanics' Institutes. The construc- tion of this working model was found to be exceedingly WAIT. 365 imperfect, but Mr. Watt soon remedied all its defects. As far as the kind of engine could answer its purpose, the apparatus was found to perform its functions satis- factorily, being annually exhibited to the class with great success. He had, however, been taught by his examination of the model what were the defects of the machine itself, and which no care in repairing or ad- justing that model could remove. He found first of all that the boiler was much too small in proportion to the column of water which the steam had to raise, and yet it was larger than the boiler used in practice. The cylinder was on the scale of two inches diameter, the height being half a foot. The vacuum being imper- fect from the size of the boiler, he diminished the length of the piston rod. He found that the brass of which the cylinder was made carried off a great deal of heat, and that too large a surface was exposed to the steam. These observations set him upon making a variety of experiments upon steam, and upon the mode of applying it both directly and to produce a vacuum. He had, in the year 1759, while a fellow-student with Mr. Robison, received from that gentleman a sugges- tion of the application of steam to wheel-carriages, as he tells us in 1803, long before steam travelling was dreamt of.* They had together made experiments on Papin's digester, in order to ascertain the expansive force of steam ; but these speculations had for several years * Mr. Murdock, in 1784, made a working model of a steam- carriage, which moved about the room. It was constructed upon the principle set forth in Mr. Watt's specification of 1769, Art. iv., and this is the very method used at the present day. 366 WAIT. been given up. In 1760 and the two following years Watt had been in familiar intercourse with Professor Black, had witnessed his experiments on heat, and had learnt from him the true cause of evaporation and condensation. When, therefore, he began to experi- ment upon the mechanical application of steam, its expansion, and its condensation, he enjoyed that ines- timable advantage of thoroughly knowing the princi- ples on which its changes and its action depended. His own experiments now put him in possession of the causes which determine the rapidity of evaporation, the proportion which it bears to the surface exposed to the fire, the effects of pressure upon the boiling-point, and the quantity of fuel required to convert a given quantity of water into steam — circumstances which had hitherto been only vaguely and generally examined, but which he now reduced to mathematical precision. The first discovery which he made upon the atmo- spheric engine and its waste of fuel, was that the in- jection of cold water which condenses the steam also cools the cylinder to a degree which requires a great expenditure of fuel again to give it the necessary heat for keeping the steam expanded to fill it. He found that three-fourths of the fuel employed were thus con- sumed ; in other words, that if the cylinder could be kept at the temperature which it has before the jet is thrown in, one-fourth of the fuel would suffice for the operation. The next defect of the process was scarcely less im- portant. The water injected, coming in contact with the steam, was itself heated ; the evolution of the latent heat, which Black's discovery showed Watt WATT. 367 necessarily took place on its condensation, had the effect, together with the absorption of the steam's sensible heat, of converting a portion of the injected water itself into steam. Hence the vacuum was very far from perfect ; and the resistance which the piston thus met with in its descent was found to be equal to one-fourth part of the atmospheric pressure, that is to say, the working power of the machine was diminished one-fourth. From the distinct view thus obtained of the evil arose the suggestion of the remedy. The whole mis- chief proceeded from the condensation being performed in the cylinder, where the steam was thrown and the piston worked. It occurred to Watt, that if the con- densation could be performed in a separate vessel, com- municating with the cylinder, the latter could be kept hot while the former was cooled, and the vapour aris- ing from the injected water could also be prevented from impairing the vacuum. The communication could easily be effected by a tube, and the water could be pumped out. This is thejirst and the grand inven- tion by which he at once saved three-fourths of the fuel, and increased the power one-fourth, thus making every pound of coal consumed produce five times the force formerly obtained from it. But this was not all. He found it expedient to remove the air from the upper part of the cylinder, as it tended to diminish the heat. In effecting this he was, secondly, led to open a com- munication with the boiler, and introduce steam above the piston while it descended, thus making the upper chamber of the cylinder air-tight. The steam thus acted in aiding the descent of the piston, instead 368 WATT. of that descent being accomplished merely by the atmospheric pressure. Thirdly — the counterpoise at the pump-rod was done away, as a mere loss of power, and the piston was now forced up- wards by the steam entering to fill the cylinder. These two great additional improvements only required a communication to be opened by tubes with the con- denser as well as the boiler, and they gave to the machinery its right to be called a steam-engine ; for it now worked more by steam than by air. The upper chamber was kept air-tight by making the piston-rod work in a socket of tow saturated with grease, called the stuffing-box, which also diminished greatly the friction of the rod. If Mr. Watt's invention had gone no further than this, we may perceive that it not only increased the power of the fuel fivefold directly, but obtained from the steam as much additional force as could be derived, the limit being only the strength of the materials, within which limit the safety-valve of Papin always enabled the engineer to keep his power. But the three particulars which have been described were not the whole of this great engineer's improvements upon the mechanism of his predecessors. The smooth working of the engine, especially if it be applied to other and finer operations than those of the miner, depends essentially on the accurate position of the piston rod, with whatever velocity moving, and against whatever weight contending. Its motion must be steadily maintained in the same vertical straight line, or in the same horizontal line, or in the same straight line whatever be its direction, without WATT. 369 shaking or inclining so as to press at all against the sides of the cylinder — any such lateral pressure occa- sioning a loss of time, a jolting motion, a general de- rangement of the machinery. The motion of the rod and the piston must be perfectly equable, continuous, and smooth : it must work, as the engineers sometimes say, sweetly, at every instant, in order that the engine may well perform its functions. The contrivance for producing this motion of the rod so that it shall be always in one line, parallel to some supposed line whether vertical, as in a mine, or horizontal, or in any other direction, is thence called the " Parallel Motion" and it is one of Mr. Watt's most exquisite discoveries, and one to which scientific principle has the most con- duced. If a circle or other curve has its curvature gra- dually changed, until from being concave to its axis it becomes convex, it will pass through every possible position or variation (whence the great refinement upon fluxions, the calculus of variations, probably derived its name, if not its origin), and at one point it will be a straight line, or will coincide with a straight line. So if a curve have two branches, one concave to the axis, the other convex, as a cubic para- bola for example, the point at which its concavity ends and its convexity begins, is called for that reason a point of contrary flexure. The contrivance of the parallel motion consists in making the contrary circu- lar motions of arms which bear on the rod always keep to the point of contrary flexure and thus give a recti- linear motion to the rod, the tendencies to disturb it correcting each other. It was long ago shown by Sir Isaac Newton, in the ' Principia,' that if a circle moves 2 B 370 WATT. upon another of twice its diameter, each point describes a straight line. This is precisely the principle of the parallel motion. Three beams are made to revolve round different centres, two of these being moveable in the arm of the engine, and one fixed without it. These three are connected together and with the piston-rods of the cylinder and the pumps, which their revolu- tions cause to describe accurately straight lines. A fifth invention is the Float, which, placed on the surface of the water in the boiler, descends until the water is so low as to require a supply ; it then opens a valve which lets in the quantity wanted ; for, as soon as it rises to a certain height, the valve is shut by the float. The most refined contrivance of the whole may now be mentioned, in the sixth and last place, the adaptation of the Governor, previously used in wind and water mills. It is evident that the velocity of the working may be increased beyond what is required or con- venient without the safety-valve giving any indi- cation of the excess, and also that the warning given by this valve does little more than point out the risk without providing the remedy or preventive. The governor is a far more subtle invention. Two balls are fixed to the end of arms which are connected with the engine by a moveable socket ; this can play up and down a vertical rod revolving by a band on the axis or spindle of the fly-wheel, and it revolves, there- fore, with the velocity of that spindle. The arms are perfectly moveable on their centres, which are fixed in the socket and on opposite sides of it. Their centrifu- gal force, therefore, makes them diverge, more or less, in proportion as the rotatory motion of the spindle and WATT. 371 consequently the velocity of the engine increases ; their divergence pushes the collar up the spindle, its axis, and as it rises, it closes, by means of cranks, a valve called the " throttle-valve," in the pipe which conveys the steam from the boiler to the cylinder, and this lessens the supply of steam : the motion of the engine is thus reduced, the centrifugal force is abated, the balls approach the spindle again, the collar de- scends, the throttle- valve is gradually opened, and the supply of steam again slowly increased, but never be- yond the quantity required, because as soon as that is exceeded, the increase of centrifugal force causes the balls to diverge, the collars to rise, and the valve to close. Thus the engine itself provides for its con- tinuing in the state of perfect adjustment required. As long as its motion continues uniform, the balls revolve at the mean distance from their axis without either receding or approaching, and the supply of steam con- tinues the same. As soon as the motion becomes ex- cessive, they diverge, and the supply of steam is dimi- nished ; as soon as the motion becomes defective, they converge, and the supply of steam is increased. But further, the balls themselves, by their increased motion, absorb part of the force, independent of their action on the throttle-valve, and so contribute to the adjustment. The sagacious inventor soon satisfied himself that he had almost created a new engine of incalculable power, universal application, and inestimable value. But he had not the funds either to try his invention upon an adequate scale so as to bring it into use, or to secure his property in it by obtaining a patent. After some repulses, he happily met with Dr. Roebuck, a 2B 2 372 WAIT. man of profound scientific knowledge, and of daring spirit as a speculator. He had just founded the Carron Iron Works, not far from Glasgow, and was lessee, under the Hamilton family, of the Kinneil Coal Works. He was the grandfather of the present Member for Bath, who, descended from him on the one side, and from the Tickells* on the other, may be said to unite in himself rare claims to hereditary dis- tinction ; but who is probably destined to exalt the name of his family still higher by his own virtues. Dr. Roebuck, like too many ingenious men, founded these Carron and Kinneil Works for the benefit of others; and though he agreed to Mr. Watt's terms of receiving two thirds of the profit, he was obliged by pecuniary embarrassments to retire from the partner- ship after a patent had been obtained in 1769, and an engine of an eighteen-inch cylinder had been erected at Kinneil. The success of this amply proved the solidity of the invention, but the inventor was obliged, for some years, to abandon the pursuit, and to labour in his profession of what is now termed a civil engineer ; but the extensive operations of which Scotland soon became the scene, gave a much more ample scope to his talents. He was actively engaged in the surveys, and afterwards in the works, for connecting by a canal the Monkland coal-mines with Glasgow. He was afterwards employed in preparing the canal since completed by Mr. Rennie, across the Isthmus of * His maternal grandfather was the author of ' Anticipation/ and grandson of Addison's friend, the poet. WATT. 373 Crinan ; in the difficult and laborious investigations for the improvement of the harbours of Ayr, Greenock, and Glasgow ; in improving the navigation of the Forth and the Clyde ; in the Campbelton Canal, and in the surveys and plans preliminary to the Grand Caledonian Canal; beside several bridges of great importance, as those of Hamilton and Rutherglen. At Dr. Roebuck's Mr. Watt had early received much kindness, and many valuable lessons in chemical science. He was here, too, introduced to Dr. Black. The various works which have been mentioned occu- pied his whole time from the disappointment experienced in 1769 respecting the steam engine, of which during that long interval he never despaired, to the year 1774, when he acceded to the proposal of Mr. Boulton, of Soho, near Birmingham, that he shoul be taken in Dr. Roebuck's place as partner in the patent, and in 1775 he settled there in this new business. An extension of the patent for twenty-five years from this time was obtained from Parliament, in consequence of the national importance which all men saw belonged to the invention ; and the partners constructed many engines upon the terms of receiving one third of the fuel saved by the improvements. It is a convenient mode of illustrating the effect of the invention in saving fuel, to observe what were the gains of the partners under this stipulation. On one mine, that of Chase water, in Cornwall, the proprietors com- pounded for 2400/. a year, instead of paying the third of the fuel saved. That saving then must very con- siderably have exceeded 72001. a year. But there seemed some difficulty in carrying bargains of this kind 374 WATT. into effect ; and the genius of Watt, fertile in resources, immediately invented a small clock, called the counter, to be moved by the engine, and which accurately re- corded every stroke it made. Payment being in propor- tion to the number of strokes, the clock was enclosed in a box under a double lock, and thus the working eould be easily and securely ascertained.* The first consequence of this grand invention, and the great saving of fuel it occasioned, was the renewed working of mines which had become unprofitable under the old plan. The next was the opening mines which Newcomen's engine could not drain at all. The steam-power, too, was no longer confined to draining mines. Various contrivances, for which Watt took out no less than four patents between 1781 and 1785, enabled him to communicate a rota- tory motion from the piston, so that the engine could now work any machinery whatever ; could spin cotton, cut 4ron and brass, stamp cloth, grind corn, print books, coin money, in short, could perform on any scale any kind of work in which human labour was either inefficient or expensive ; and while it was seen in one place pouring out rivers from the bowels of the earth with the arms of a giant, or cleaving rocks of granite formation, or clipping huge bars of stubborn iron into ribands, it was elsewhere to be found * Such an engine could not be made and used secretly, and thus piracy was prevented. It is far otherwise with small pieces of mechanism, and still more difficult would be the protection of patent rights in mere methods, though to these the protection of the law should be extended. WATT. 375 weaving or spinning like a quiet and industrious fe- male, or turning a small lathe, or forming the fine wheels of a watch, or drawing out a thread too fine for sight ; when the machine, instead of sawing the air aloft, and making the ground tremble around it, was placed quietly on a table like a candlestick or an inkstand. The latest use of the power, and the most important, is steam travelling by land and water. Watt himself early perceived this application of his engine ; and in 1785 he took out a patent for moving carriages by steam, but he does not appear to have practically used his method. The attempts had been numerous, and from very early times, to propel vessels by steam. There seems reason to think that the paddle-wheel, the only addition to the steam-engine required for navigation, was known in ancient Egypt : it certainly was known to the Romans. In the middle of the sixteenth century a Spanish engineer exhibited a steam-vessel to Charles V. The Marquis of Wor- cester appears to have turned his attention to the subject from some parts of the work already cited, and so superciliously condemned by Hume ; and Jonathan Hulls, in 1736, took out a patent for a kind of steam- tug. Various similar attempts were afterwards made, but with no success, and it was not until the steam- engine had been improved and had become generally used for all other purposes that it was applied to those of locomotion. It is truly painful to reflect, that among the rewards which this great public benefactor was destined to reap for his invaluable services, was the lot of having to pass many years of his life in the unenviable situa- 376 WATT. tion of a party to suits at law and in equity, so numerous as might well have worn out the patience of any one but him, whose unwearied perseverance had already toiled successfully against unnumbered difficulties of another kind. Such was, at that time, the patent law of this country ; such, in some degree, it still is, though much improved. Inventive genius is placed between two dangers, and it can hardly escape the one without falling into the other. — If the invention is such that it requires some new demand to be created, or some novel taste to be introduced, before it can be much used, the period of the monopoly expires before any gain can be reaped. This is the more likely to happen if it comes in competition with things already made, and of which, at some expense, a considerable stock has been prepared, because a formidable interest is combined against the use of that new method which must displace the old, and render valueless this col- lected stock. I remember sitting on the trial of a patent for a new and admirable pianoforte ; the only witness to its excellence being a sculptor of distinction who had once made such instruments, but had no longer any interest in crying down the invention : none of the trade could be trusted to give their opinion upon oath ; all were, of course, in a combination against that improvement, which, if adopted, would render unsaleable their pianofortes already made, — If, on the other hand, the superiority of the invention is quite manifest, if the demand for it already exists, if no combination can prevent its coming into general use — for example, the making a new instrument for perform- ing a known and necessary operation, or a new substance WATT, 377 for supplying a general want already existing — then the inventor has to prepare himself for encountering piracy in all its forms; capitalists, who would be ashamed to violate the law in their own persons, en- couraging men of no substance to infringe the patent, and omitting to pay the patentee's costs when these tools are defeated. My learned and ingenious kins- man, Dr. Forsyth, the inventor of the percussion lock, passed the fourteen years of his patent right in courts of justice, and in every instance prevailed ; but he found the pirates pennyless, the costs were to be paid, and he never gained one shilling by an invention which is, I believe, more universally used all over Europe than any other, except, perhaps, Argand's lamp. That invention was defeated in court, in con- sequence of the imperfect state of the law in those days, and of the absurd leaning of the Judges against all patentees ; their Lordships displaying the utmost ingenuity in discovering flaws, and calling into action all the resources of legal astuteness in grinding, as they went on, new law for the defeat of the inventor. Of this, one instance only needs be given. If a speci- fication contained ten good matters or processes, and by oversight one was either not original, or did not answer the description given in any other respect,* the courts held the patent wholly void, and not merely void for the erroneously described part, upon the subtle and senseless ground that the Crown had been deceived in the grant. * Turner v. Winter, 6 T. R. ; Rex v. Fuller, 3 B. and A. My Acts of 1835 and 1840 have in great part remedied these sad defects in the law ; others still remain. 378 WAIT. Mr. Watt had to struggle against this state of the law as well as against the shameless frauds, the conspiracies of dishonest, unprincipled men. During seven years and upwards he was condemned to lead the life of litigation ; during seven years his genius was withdrawn from his own pursuits to become what he, no doubt, had, unfortunately for society, full time to make himself, an accomplished and learned lawyer; and it was not till five and thirty years after his invention had been made, that he was finally freed by a decision of the Court of King's Bench, in 1799, from a durance which lasted all the term of his patent, after all interest in the subject had expired by efflux of time. It was proved before a committee of the House of Commons in 1834, that had his statutory term in the patent only been secured to him, he would have been a great loser by the in- vention; and that for some years after the Act of Parliament had extended the time, he still was out of pocket : consequently it follows, that had he never taken a patent at all, but trusted entirely to the pre- ference which his being the inventor would have given him in the market, as a maker of steam-ap- paratus, that is, had he taken only this indirect benefit instead of the direct gains of the monopoly, he would have been better off in a pecuniary point of view than he was by means of the grant of the patent and its Parliamentary extension. The Act which I introduced in 1835, grounded mainly upon that evidence, has removed some of the greatest defects in the law ; and it has enabled, when coupled with the subsequent Act of last Session, an inventor to obtain, WATT. 379 at a very inconsiderable cost, an extension for any additional period, not exceeding the duration of the original patent.* The expenses of obtaining patents, and especially the grievous burden of having to take out one for each of the three kingdoms, are the principal parts of the grievance which remain to be redressed. Notwithstanding the serious drawbacks upon his gains which Watt thus experienced, he was, on the whole, successful in respect of profit, realizing an ample fortune, but which all men wished had been greater, and which, under a more just law, would have been thrice as great. We have been contemplating the great achievement of Watt, but it would be a mistake to suppose that the steam-engine is the only monument of his scientific genius or his inventive skill. He was the author of the machine in general use for copying letters ; of the method extensively used for heating buildings and hot-houses by steam ; and of an ingenious mechanism for multiplying copies of busts and other sculptures ; but he was also, without any doubt, the person who first discovered the composition of water. At this * The course which a patentee ought to pursue if there be no opposition to his claim of extension, is to employ no solicitor and no counsel, but to appear in person before the Judicial Com- mittee, as my gallant and truly ingenious friend Lord Dundonald (better known as Lord Cochrane) lately did. Their Lordships will always favour such a course, the rather as they thus obtain the advantage of hearing the explanations required from the person best able to give them. In opposed cases professional aid is requisite. 380 WATT. most important truth he arrived by a profound ex- amination of all the experiments which had been made by Warltire, by Macquer, and especially by Priest- ley, upon the combustion of hydrogen and oxygen gases, then called inflammable, and vital or dephlo- gisticated airs. No former reasoner had come even near the true theory of the phenomena observed in those experiments. All had assumed that water was a simple or elementary body ; that it was contained in the airs burnt together, and was precipitated by their explosion. He, on the contrary, showed that it was formed by the union of the two gases, and their parting with the latent heat which had held them in the elastic or gaseous state, but which being with- drawn by their union, left them in a state of liquid or aqueous fluidity. As early as 1782, his attention had been closely directed to the experiments in which air is produced from water, and especially to those upon the com- bustion of inflammable air. In December of that year he had matured his theory, for we find him then an- nouncing to De Luc his discovery, that " one element must be dismissed from the list ;" water being, ac- cording to his doctrine (stated more explicitly to Dr. Black, April 1783r) " composed of dephlogisticated and inflammable airs deprived of a portion of their latent heat." To his whole correspondence with that great philosopher, with Smeaton, with Priestley, De Luc, and others, I have had access, and no trace is to be found in it that either he or they had even entertained the least suspicion of the same thing having before occurred WATT. to any one else.* It is to be noted, too, that in 1 784 Mr. Cavendish, after his celebrated experiment, had not attained by any means so clear a notion of the true doctrine as Mr. Watt explains in those previous letters, f I examined minutely the whole of this subject eight years ago, at the request of my dis- tinguished colleague M. Arago, then engaged in preparing his * Eloge' of Mr. Watt, who had also been our fellow-member of the Institute. The reader will find my statement of the evidence annexed to this account. But I cannot easily suppose that M. Arago ever intended, and I know that I never myself intended, to insinuate in the slightest degree a suspicion of Mr. Cavendish's having borrowed from Mr. Watt. He had, in all probability, been led to the same conclusion by his own researches, ignorant of Mr. Watt's speculations, a little earlier in point of time, just as Priestley when claiming, and justly claiming, the important discovery of oxygen (called by him, in accordance with the doctrine of Stahl, " dephlogisticated air"), never denied that Scheele also made the same discovery, calling it " empyreal air," without being aware of another having preceded him. Priestley, of course, treated the dis- creditable proceedings of Lavoisier in respect to this gas very differently, and so must all impartial men. It must on no account be supposed that Watt cannot be considered as having discovered the composition of water, merely because he made no new experiments of particular moment, like Cavendish, to ascertain that * Letters to Gilbert Hamilton of Glasgow, Fry of Bristol, Smeaton, De Luc— all dated March and April, 1783. •f See Life of Cavendish for further particulars and explanations. 382 WATT. capital point. No one refuses to Newton the discovery of gravitation as the controlling and directing power of the solar system ; and yet he made not one of those observations upon which his theory rests ; nay, he threw it aside for sixteen years when the erroneous notion of a degree being only sixty miles appeared by its consequences to disprove his proposition, and instead of making any further experiments himself, waited until Picard's more accurate measurement became known to him accidentally in 1682, and enabled him to demonstrate his doctrine. In like manner, Lavoi- sier, who discovered no gas, and made no original experiments of the least value in pneumatic chemistry, is universally admitted to have discovered the true theory of combustion and calcination, by reasoning on the facts which others had ascertained. Watt's happy inference from the facts discovered by Warltire and Priestley was just as much entitled, and for the same reasons, to be regarded as the discovery of the composition of water. The latter years of Mr. Watt's useful and honour- able life were passed in the bosom of his family and the society of his friends, although he ever gave the due attention to the extensive concerns of the house in which he was the principal partner. He had been married as early as 1764 to Miss Miller, his cousin, and had by her a daughter who predeceased him, leaving children, and a son, James, who still survives, inherit- ing the scientific tastes, the extensive knowledge, the masculine understanding, and the scrupulous integrity of his father. With the late Mr. Robinson Boulton and Mr. Gregory Watt, he was admitted into the part- WATT. nership, the concerns of which he extended, and, for the last quarter of a century, almost exclusively conducted. By his second wife, Miss Macgregor, whom he married in 1776, he had one son, Gregory, who unfortunately died in October, 1804, at the age of twenty- seven, after giving an earnest of brilliant ta- lents and accomplishments. This loss was, no doubt, a severe blow to his family, and the father shared fully in their sorrow. But he bore it like a man : and I feel great satisfaction in correcting an error into which my illustrious friend and colleague M. Arago has fallen through misinformation, when he represents Mr. Watt's spirit as so entirely broken by the misfortune that he " preserved an almost total silence during the latter years of his life." The fact is, that he survived his son's death between fourteen and fifteen years, and never was more cheerful or enjoyed the pleasures of society more heartily than during this period. I can speak on the point with absolute certainty, for my own acquaintance with him commenced after my friend Gregory's decease. A few months after that event, he calmly and with his wonted acuteness discussed with me the composition of an epitaph to be inscribed on his son's tomb. That autumn and winter he was a constant attendant at our Friday club, and in all our private circles, and was the life of them all. He has, moreover, left under his hand an account of the effect which the recent loss had produced upon his spirits, and a flat contradiction to the notion that it had de- pressed them. " I perhaps," he observes, "have said too much to you and Mr. Campbell on the state of my mind : I therefore think it necessary to say that I am 384 WATT, not low-spirited, and were you here you would find me as cheerful in the company of my friends as usual ; my feelings for the loss of poor Gregory are not passion, but a deep regret that such was his and my lot." He then expresses his pious resignation to the will of " the Disposer of events." It is true, he adds that he had lost one stimulus to exertion, and with it his relish for his usual avocations, but he looks to time for a remedy, and adds, " meanwhile, I do not neglect the means of amusement which are within my power." This letter was written in January 1805, only a few weeks after the loss of his son. In another letter written in April to the same gentleman, his cousin, Mr. Muirhead, great uncle of the able and learned translator of M. Arago's ( Eloge,' after expressing his confident hopes that Gregory had changed this mortal state for a far happier existence, he says, as if anxious to avoid all suspicion of his giving way to excessive sorrow, " You are not to conceive that we give way to grief : on the contrary, you will find us as cheerful as we ought to be, and as much disposed to enjoy the friends we have left as ever. But we should approach to brutes if we had no regrets." In this letter he quotes the beautiful lines of Catullus, " Nunc it per iter tenebricosum," &c. To this evidence at the period of his son's death let me add the testimony of Lord Jeffrey, who knew him well, and who brings down the account to the latest years of his life. " His health, which was deli- cate from his youth upwards, seemed to become firmer as he advanced in years ; and he possessed, up almost to the last moments of his existence, not only the full command of his extraordinary intellect, but all the WATT. 385 alacrity of spirit arid the social gaiety which had illu- mined his happiest days. His friends in this part of the country (Edinburgh) never saw him more full of intellectual vigour and colloquial animation, never more delightful or more instructive, than in his last visit in autumn 1817." It was after this period that he invented the machine for copying sculpture. He distributed among his friends some specimens of its performances, jocularly calling them " the productions of a young artist just entering into his eighty-third year." In the summer of the following year, 1819, 1 saw him for the last time, and did not observe any change in his conversation or in his manner ; but I understand that he suffered some inconvenience through the summer ; though, until a few weeks before his death, he was not seriously indisposed. He soon became aware of the event which was approaching, and he seemed only anxious to impress upon his sorrowing family the circumstances cal- culated to minister consolation under the change which must soon take place. He expressed his sincere gratitude to Divine Providence for the blessings which he had been permitted to enjoy, for his length of days, his exemption from the infirmities of age, the calm and cheerful evening of his life passed after the useful labours of its day had closed. He died on the 25th of August, 1819, in his eighty-fourth year. His remains lie buried in Handsworth church, near his residence of Heath field, and a statue, the work of Chan trey, is there erected to his memory by his son ; and the same filial piety has presented a statue to the College of Glas- gow, in grateful recollection of early patronage. But a truly noble monument is raised to him in West- 2 c 386 WATT. minster Abbey, by the genius of Chantrey, at the expense of the Sovereign and of many Peers and distinguished Commoners, who held a meeting in honour of this illustrious man and great public bene- factor. The Ministers of the Crown, and the chiefs of the opposition in either House of Parliament, the most eminent men of science, the most distinguished cultivators of the arts, assembled with this view, and the account of their proceedings was made public in an authentic form. The Prime Minister, Lord Liver- pool, presided ; and it was none of the least remarkable passages of that day, that his successor, the present Premier, was anxious to declare the obligation under which he lay to the genius of him they were comme- morating, the fortunes of his family being reared by manufacturing industry, founded upon the happy inventions of Arkwright and Watt. It has ever been reckoned by me one of the chief honours of my life, that I was called upon to pen the inscription upon the noble monument thus nobly reared. The chisel of Chantrey, whose greatest work this certainly is, has admirably presented the features of the countenance at once deeply meditative and calmly placid, but betokening power rather than delicacy and refinement. The civilized world is filled with im- perishable records of his genius, and the grateful recollection of the whole species embalms his memory. But for this, the author of the epitaph might well feel how inadequately his feeble pen had performed its office in attempting to pourtray such excellence : how much more inadequately when its lines are traced in most disadvantageous contrast with the signal success of the sculptor ! He who has ever made the attempt to write WATT. 387 with a chisel in our language, little lapidary as it cer- tainly is, will comprehend the extraordinary difficulties of the task, and will show mercy to the failure : — NOT TO PERPETUATE A NAME WHICH MUST ENDURE WHILE THE PEACEFUL ARTS FLOURISH BUT TO SHEW THAT MANKIND HAVE LEARNED TO HONOUR THOSE WHO BEST DESERVE THEIR GRATITUDE THE KING HIS MINISTERS AND MANY OF THE NOBLES AND COMMONERS OF THE REALM RAISED THIS MONUMENT TO JAMES WATT WHO DIRECTING THE FORCE OF AN ORIGINAL GENIUS EARLY EXERCISED IN PHILOSOPHIC RESEARCH TO THE IMPROVEMENT OF THE STEAM ENGINE ENLARGED THE RESOURCES OF HIS COUNTRY INCREASED THE POWER OF MAN AND ROSE TO AN EMINENT PLACE AMONG THE MOST ILLUSTRIOUS FOLLOWERS OF SCIENCE AND THE REAL BENEFACTORS OF THE WORLD BORN AT GREENOCK MDCCXXXVI DIED AT HEATHFIELD IN STAFFORDSHIRE MDCCCXIX. We have been considering this eminent person as yet only in his public capacity, as a benefactor of mankind by his fertile genius and indomitable perse- verance ; and the best portraiture of his intellectual character was to be found in the description of his attainments. It is, however, proper to survey him also in private life. He was unexceptionable in all its relations ; and as his activity was unmeasured, and his taste anything rather than fastidious, he both was master of every variety of knowledge, and was tolerant of discussion on subjects of very subordinate importance compared with those on which he most excelled. Not 2c2 388 WATT. only all the sciences from the mathematics and astro- nomy, down to botany, received his diligent attention, but he was tolerably read in the lighter kinds of literature, delighting in poetry and other works of fiction, full of the stores of ancient literature, and readily giving himself up to the critical disquisitions of commentators, and to discussions on the fancies of etymology. His manners were most attractive from their perfect nature and simplicity. His conversation was rich in the measure which such stores and such easy taste might lead us to expect, and it astonished all listeners with its admirable precision, with the extra- ordinary memory it displayed, with the distinctness it seemed to have, as if his mind had separate niches for keeping each particular, and with its complete rejection of all worthless and superfluous matter, as if the same mind had some fine machine for acting like a fan, casting off the chaff and the husk. But it had besides a peculiar charm from the pleasure he took in convey- ing information where he was peculiarly able to give it, and in joining with entire candour whatever discussion happened to arise. Even upon matters on which he was entitled to pronounce with absolute authority, he never laid down the law, but spoke like any other partaker of the conversation. You might ob- serve him, however, with his pencil in his hand, ready to prove what might require explanation, and he was an adventurous disputant who would not rather see his in- tellect play in illustrations than descend with demon- strative force. He was ever in pursuit of truth or the gratification of a rational curiosity, and this attempered as well as guided his talk. If he seemed occasionally to be moved beyond the interest thus excited, it was when WATT. 389 lie perceived any thing uncandid or unfair, or, above all, indirect and dishonest. The attempts of one man to appropriate another's inventive merit were the things that most roused his indignation ; for, regarding dis- covery and invention as the most precious of all property, he could not bear the sight of its violation, and would stop minutely and curiously to ascertain the relative shares of different individuals, when any doubt was raised upon the distribution. His conversation was withal spirited and lively — it was easy and concise, and without the least of a lecturing formality. His voice was deep and low, and if somewhat monotonous, it yet seemed in harmony with the weight and the beauty of his discourse, through which however there also ran a current of a lighter kind ; for he was mirth- ful, temperately jocular, nor could anything to more advantage set off the living anecdotes of men and things, with which the graver texture of his talk was interwoven, than his sly and quiet humour, both of mind and of look, in recounting them. No one who had the happiness of knowing him, no member, more especially, of the club in Edinburgh which he frequented as often as he visited that capital, can ever forget the zest which his society derived from the mixture of such various matters as those to which I have referred ; and one of its most distinguished founders * has justly * Lord Jeffrey. The club was called from the day, Friday, on which it met at supper, after the business of the week was over, and the half-holiday of Saturday only lightly hanging over the heads of the lawyers, who chiefly composed it.

Drummond, and several who still survive and fill exalted places in the State. 390 WAIT. said, that in no other person was there ever observed so " fine an expression of reposing strength and unin- terrupted self-possession as marked his whole manner." APPENDIX. HISTORICAL NOTE ON THE DISCOVERY OF THE THEORY OF THE COMPOSITION OF WATER. THERE can be no doubt whatever, that the experiment of Mr. Warltire, related in Dr. Priestley's fifth volume,* gave rise to this inquiry, at least in England ; Mr. Cavendish expressly * Mr. Warltire's letter is dated Birmingham, 18th April, 1781, and was published by Dr. Priestley in the Appendix to the seventh volume of his ' Experiments and Observations relating to various branches of Natural Philosophy ; with a continuation of the Ob- servations on Air,' — forming, in fact, the fifth volume of his ' Ex- periments and Observations on different kinds of Air ;' printed at Birmingham in 1781. Mr. Warltire's first experiments were made in a copper ball or flask, which held three wine pints, the weight 14 ounces ; and his ob- ject was to determine " whether heat is heavy or not." After stating his mode of mixing the airs, and of adjusting the balance, he says, he " always accurately balanced the flask of common air, then found the difference of weight after the inflammable air was introduced, that he might be certain he had confined the proper proportion of each. The electric spark having passed through them, the flask became hot, and was cooled by exposing it to the common air of the room : it was then hung up again to the balance, and a loss of weight was always found, but not constantly the same ; upon an average it was two grains." He goes on to say, u I have fired air in glass vessels since I saw you (Dr. Priestley) venture to do it, and I have observed, as you did, that, though the glass was clean and dry before, yet, after firing the air, it became dewy, and was lined with a sooty substance." It WAIT. 391 refers to it, as having set him upon making his experiments. — (Phil. Trans. 1784, p. 126.) The experiment of Mr. Warltire consisted in firing, by electricity, a mixture of inflammable and common air in a close vessel, and two things were said to be observed : first, a sensible loss of weight ; second, a dewy deposit on the sides of the vessel. Mr. Watt, in a note to p. 332 of his paper, Phil. Trans. 1784, inadvertently states, that the dewy deposit was first observed by Mr. Cavendish; but Mr. Cavendish himself, p. 127, expressly states Mr. Warltire to have observed it, and cites Dr. Priestley's fifth volume. Mr. Cavendish himself could find no loss of weight, and he says that Dr. Priestley had also tried the experiment, and found none.* But Mr. Cavendish found there was always a dewy deposit, without any sooty matter. The result of many trials was, that common air and inflammable air being burnt together, in the proportion of 1000 measures of the former to 423 of the latter, " about one-fifth of the common air, and nearly all the inflammable air, lose their elasticity, and are condensed into the dew which lines the glass." He examined the dew, and found it to be pure water. He therefore concludes, that " almost all the inflammable air, and about one-sixth of the common air, are turned into pure water." Mr. Cavendish then burned, in the same way, dephlogisti- cated and inflammable airs (oxygen and hydrogen gases), and the deposit was always more or less acidulous, accord- ingly as the air burnt with the inflammable air was more or less phlogisticated. The acid was found to be nitrous. Mr. Cavendish states, that " almost the whole of the inflammable and dephlogisticated air is converted into pure water ;" and, again, that " if these airs could be obtained perfectly pure, the It seems evident that neither Mr. Warltire nor Dr. Priestley attributed the dew to anything else than a mechanical deposit of the moisture suspended in common air. — [NOTE BY MR. JAMES WATT.] * Mr. Cavendish's note, p. 127, would seem to imply this; but I have not found in any of Dr. Priestley's papers that he has said so. —[NOTE BY MR. JAMES WATT.] 392 WATT. whole would be condensed." And he accounts for common air and inflammable air, when burnt together, not producing acid, by supposing that the heat produced is not sufficient. He then says that these experiments, with the exception of what relates to the acid, were made in the summer of 1781, and mentioned to Dr. Priestley ; and adds, that " a friend of his (Mr. Cavendish's), last summer (that is, 1783), gave some account of them to M. Lavoisier, as well as of the conclu- sion drawn from them, that dephlogisticated air is only water deprived of its phlogiston ; but, at that time, so far was M. Lavoisier from thinking any such opinion warranted, that till he was prevailed upon to repeat the experiment himself, he found some difficulty in believing that nearly the whole of the two airs could be converted into water." The friend is known to have been Dr., afterwards Sir Charles Blagden; and it is a remarkable circumstance, that this passage of Mr. Cavendish's paper appears not to have been in it when ori- ginally presented to the Royal Society ; for the paper is appa- rently in Mr. Cavendish's hand, and the paragraph, p. 134, 135, is not found in it, but is added to it, and directed to be inserted in that place. It is, moreover, not in Mr. Cavendish's hand, but in Sir Charles Blagden's ; and, indeed, the latter must have given him the information as to M. Lavoisier, with whom it is not said that Mr. Cavendish had any corre- spondence. The paper itself was read 15th January, 1784. The volume was published about six months afterwards. M. Lavoisier's memoir (in the Mem. de I'Academie dcs Sciences for 1781) had been read partly in November and December 1783, and additions were afterwards made to it. It was published in 1784. It contained M. Lavoisier's account of his experiments in June 1783, at which, he says, Sir Charles Blagden was present ; and it states that he told M. Lavoisier of Mr. Cavendish having " already burnt inflamma- ble air in close vessels, and obtained a very sensible quantity of water." But he, M, Lavoisier, says nothing of Sir Charles Blagden having also mentioned Mr. Cavendish's conclusion from the experiment. He expressly states, that the weight of the water was equal to that of the two airs burnt, unless the heat and light which escape are ponderable, w hich he hold WATT. 393 them not to be. His account, therefore, is not reconcilable with Sir Charles Blagden's, and the latter was most probably written as a contradiction of it, after Mr. Cavendish's paper had been read, and when the Memoires of the Academic were received in this country. These Memoires were published in 1784, and could not, certainly, have arrived when Mr. Cavendish's paper was written, nor when it was read to the Royal Society. But it is farther to be remarked, that this passage of Mr. Cavendish's paper in Sir Charles Blagden's handwriting, only mentions the experiments having been communicated to Dr. Priestley; they were made, says the passage, in 1781, and communicated to Dr. Priestley ; it is not said when, nor is it said that " the conclusions drawn from them," and which Sir Charles Blagden says he communicated to M. Lavoisier in summer 1783, were ever communicated to Dr. Priestley; and Dr. Priestley, in his paper (referred to in Mr. Cavendish's), which was read June 1783, and written before April of that year, says nothing of Mr. Cavendish's theory, though he mentions his experiment. Several propositions then are proved by this statement. first. That Mr. Cavendish, in his paper, read 1 5th January, 1784, relates te capital experiment of burning oxygen and hydrogen gases in a close vessel, and finding pure water to be the produce of the combustion. Secondly, That, in the same paper, he drew from this expe- riment the conclusion that the two gases were converted or turned into water. Thirdly, That Sir Charles Blagden inserted in the same paper, with Mr. Cavendish's consent, a statement that the experiment had first been made by Mr. Cavendish in summer 1781, and mentioned to Dr. Priestley, though it is not said when, nor is it said that any conclusion was mentioned to Dr. Priestley, nor is it said at what time Mr. Cavendish first drew that conclusion. A most material omission. Fourthly, That in that addition made to the paper by Sir Charles Blagden, he conclusion of Mr. Cavendish is stated to be, that oxygen gas is water deprived of phlogiston; this addition having been made after M. Lavoisier's memoir arrived in England. 394 WAIT. It may further be "observed, that in another addition to the paper, which is also in Sir C. Blagden's handwriting, and which was certainly made after M. Lavoisier's memoir had arrived, Mr. Cavendish for the first time distinctly states, as upon M. Lavoisier's hypothesis, that water consisted of hydrogen united to oxygen gas. There is no substantial difference, perhaps, between this and the conclusion stated to have been drawn by Mr. Cavendish himself, that oxygen gas is water deprived of phlogiston, supposing phlogiston to be synonymous with hy- drogen ; but the former proposition is certainly the more dis- tinct and unequivocal of the two : and it is to be observed that Mr. Cavendish, in the original part of the paper, i. e. the part read January 1784, before the arrival of Lavoisier's, considers it more just to hold inflammable air to be phlogisticated Avater than pure phlogiston (p. 140). We are now to see what Mr. Watt did ; and the dates here become very material. It appears that he wrote a letter to Dr. Priestley on 26th April, 1783, in which he reasons on the experiment of burning the two gases in a close vessel, and draws the conclusion, " that water is composed of dephlogisti- cated air and phlogiston, deprived of part of their latent heat."* The letter was received by Dr. Priestley and de- livered to Sir Joseph Banks, with a request that it might be read to the Royal Society ; but Mr. Watt afterwards desired this to be delayed, in order that he might examine some new- experiments of Dr. Priestley, so that it was not read until the 22d April, 1784. In the interval between the delivery of * It may with certainty be concluded from Mr. Watt's private and unpublished letters, of which the copies taken by his copying- machine, then recently invented, are preserved, that his theory of the composition of water was already formed in December 1782, and probably much earlier. Dr. Priestley, in his paper of 21st April, 1783, p. 416, states, that Mr. Watt, prior to his (the Doctor's) ex- periments, had entertained the idea of the possibility of the conver- sion of water or steam into permanent air. And Mr. Watt himself, in his paper, Phil. Trans., p. 335, asserts, that for many years he had entertained the opinion that air was a modification of water, and he enters at some length into the facts and reasoning upon which that deduction was founded.— ["NOTE BY MR. JAJYJES WATT.] WATT. this letter to Dr. Priestley, and the reading of it, Mr. Watt had addressed another letter to M. de Luc, dated 26th No- vember, 1783,* with many further observations and reasonings, but almost the whole of the original letter is preserved in this, and is distinguished by inverted commas. One of the passages thus marked is that which has the important conclusion above mentioned ; and that letter is stated, in the subsequent one, to have been communicated to several members of the Royal Society at the time of its reaching Dr. Priestley, viz. April, 1783. In Mr. Cavendish's paper as at first read, no allusion is to be found to Mr. Watt's theory ; but in an addition made in Sir C. Blagden's own hand, after Mr. Watt's paper had been * The letter was addressed to M. J. A. de Luc, the well-known Genevese philosopher, then a Fellow of the Royal Society, and Reader to Queen Charlotte. He was the friend of Mr. Watt, who did not then belong to the Society. M. de Luc, following the motions of the Court, was not always in London, and seldom at- tended the meetings of the Royal Society. He was not present when Mr. Cavendish's paper of 15th January, 1784, was read ; but, hearing of it from Dr. Blagden, he obtained a loan of it from Mr. Cavendish, and writes to Mr. Watt on the 1st March following, to apprise him of it, adding that he has perused it, and promising an analysis. In the postscript he states, " In short, they expound and prove your system, word for word, and say nothing of you." The promised analysis is given in another letter of the 4th of the same month. Mr. Watt replies on the 6th, with all the feelings which a conviction he had been ill-treated was calculated to inspire, and makes use of those vivid expressions which M. Arago has quoted ; he states his intention of being in London in the ensuing week, and his opinion, that the reading of his letter to the Royal Society will be the proper step to be taken. He accordingly went there, waited upon the President of the Royal Society, Sir Joseph Banks, was re- ceived with all the courtesy and just feeling which distinguished that most honourable man ; and, it was settled that both the letter to Dr. Priestley of 26th April, 1783, and that to M. de Luc of 26th November, 1783, should be successively read. The farmer was done on the 22d, and the latter on the 29th April, 178,4.— [NOTE BY MB. JAMES WATT.] 396 WATT. read, there is a reference to that theory (Phil. Trans. 1784, p. 140), and Mr. Cavendish's reasons are given for not en- cumbering his theory with that part of Mr. Watt's which regards the evolution of latent heat. It is thus left somewhat doubtful, whether Mr. Cavendish had ever seen the letter of April 1783, or whether he had seen only the paper (of 26th November, 1783) of which that letter formed a part, and which was read 29th April, 1784. That the first letter was for some time (two months, as appears from the papers of Mr. Watt) in the hands of Sir Joseph Banks and other members of the Society, during the preceding spring, is certain, from the statements in the note to p. 330 ; and that Sir Charles Blagden, the Secretary, should not have seen it, seems impossible ; for Sir Joseph Banks must have delivered it to him at the time when it was intended to be read at one of the Society's meetings (Phil. Trans., p. 330, Note), and, as the letter itself remains among the Society's Records, in the same volume with the paper into which the greater part of it was introduced, it must have been in the custody of Sir C. Blagden. It is equally difficult to suppose, that the person who wrote the remarkable passage already referred to, re- specting Mr. Cavendish's conclusions having been communi- cated to M. Lavoisier in the summer of 1783 (that is, in June), should not have mentioned to Mr. Cavendish that Mr. Watt had drawn the same conclusion in the spring of 1783 (that is, in April at the latest). For the conclusions are identical, with the single difference, that Mr. Cavendish calls dephlogisticated air, water deprived of its phlogiston, and Mr. Watt says that water is composed of dephlogisticated air and phlogiston. We may remark, there is the same uncertainty or vague- ness introduced into Mr. Watt's theory, which we before ob- served in Mr. Cavendish's, by the use of the term Phlogiston, without exactly defining it. Mr. Cavendish leaves it uncer- tain, whether or not he meant by phlogiston simply inflamma- ble air, and he inclines rather to call inflammable air, water united to phlogiston. Mr. Watt says expressly, even in his later paper (of November 1783), and in a passage not to be found in the letter of April 1783, that he thinks that inflam- WATT. 397 mable air contains a small quantity of water, and much elementary heat. It must be admitted that such expressions as these on the part of both of those great men, betoken a certain hesitation respecting the theory of the composition of water. If they had ever formed to themselves the idea, that water is a compound of the two gases deprived of their latent heat, — that is, of the two gases, — with the same distinctive- ness which marks M. Lavoisier's statement of the theory, such obscurity and uncertainty would have been avoided. Several further propositions may now be stated, as the re- sult of the facts regarding Mr. Watt. First, That there is no evidence of any person having re- duced the theory of composition to writing, in a shape which now remains, so early as Mr. Watt. Secondly, That he states the theory, both in April and No- vember 1783, in language somewhat more distinctly referring to composition than Mr. Cavendish does in 1784, and that his reference to the evolution of latent heat renders it more dis- tinct than Mr. Cavendish's. Thirdly, That there is no proof, nor even any assertion, of Mr. Cavendish's theory (what Sir C. Blagden calls his con- clusion) having been communicated to Dr. Priestley before Mr. Watt stated his theory in 1783, still less of Mr. Watt having heard of it, while his whole letter shows that he never had been aware of it, either from Dr. Priestley, or from any other quarter. Fourthly, That Mr. Watt's theory was well known among the members of the Society, some months before Mr. Caven- dish's statement appears to have been reduced into writing, and eight months before it was presented to the Society. We may, indeed, go further, and affirm, as another deduction from the facts and dates, that as far as the evidence goes, there is proof of Mr. Watt having first drawn the conclusion, at least that no proof exists of any one having drawn it so early as he is proved to have done. Lastly, That a reluctance to give up the doctrine of phlo- giston, a kind of timidity on the score of that long-established and deeply rooted opinion, prevented both Mr. Watt and Mr. Cavendish from doing full justice to their own theory ; while 398 WATT. M. Lavoisier, who had entirely shaken off these trammels, first presented the new doctrine in its entire perfection and consistency. All three may have made the important step nearly at the same time, and unknown to each other ; the step, namely, of concluding from the experiment, that the two gases entered into combination, and that water was the result ; for this, with more or less of distinctness, is the inference which all three drew. But there is the statement of Sir Charles Blagden, to show that M. Lavoisier had heard of Mr. Cavendish's drawing this inference before his (M. Lavoisier's) capital experiment was made ; and it appears that M. Lavoisier, after Sir C. Blagden's statement had been embodied in Mr. Cavendish's paper and made public, never gave any contradiction to it in any of his subsequent memoirs which are to be found in the Me- moires de 1' Academic, though his own account of that ex- periment, and of what then passed, is inconsistent with Sir Charles Blagden's statement. But there is not any assertion at all, even from Sir C. Blag- den, zealous for Mr. Cavendish's priority as he was, that Mr. Watt had ever heard of Mr. Cavendish's theory before he formed his own. Whether or not Mr. Cavendish had heard of Mr. Watt's theory previous to drawing his conclusions, appears more doubtful. The supposition that he had so heard, rests on the improbability of his (Sir Charles Blagden's) and many others knowing what Mr. Watt had done, and not communicat- ing it to Mr. Cavendish, and on the omission of any assertion in Mr. Cavendish's paper, even in the part written by Sir C. Blagden with the view of claiming priority as against M. Lavoisier, that Mr. Cavendish had drawn his conclusion before April 1783, although in one of the additions to that paper reference is made to Mr. Watt's theory. As great obscurity hangs over the material question at what time Mr. Cavendish first drew the conclusion from his experi- ment, it may be as well to examine what that great man's habit was in communicating his discoveries to the Koyal Society. WATT. 399 A Committee of the Royal Society, with. Mr. Gilpin the clerk, made a series of experiments on the formation of nitrous acid, under Mr. Cavendish's direction, and to satisfy those who had doubted his theory of its composition, first given accidentally in the paper of January 1784, and afterwards more fully in another paper, June 1785. Those experiments occupied from the 6th December, 1787, to 19th March, 1788, and Mr. Cavendish's paper upon them was read 17th April, 1788. It was, therefore, written and printed within a month of the experiments being concluded. Mr. Kirwan answered Mr. Cavendish's paper (of 15th January, 1784) on water, in one which was read 5th February, 1784, and Mr. Cavendish replied in a paper read 4th March, 1784. Mr. Cavendish's experiments on the density of the earth were made from the 5th August, 1797, to the 27th May, 1798. The paper upon that subject was read 27th June, 1798. The account of the eudiometer was communicated at apparently a greater interval ; at least the only time men- tioned in the account of the experiments is the latter half of 1781, and the paper was read January 1783. It is, however, probable, from the nature of the subject, that he made further trials during the year 1782. That Mr. Watt formed his theory during the few months or weeks immediately preceding April 1783, seems probable.* It is certain that he considered the theory as his own, and makes no reference to any previous communication from any one upon the subject, nor of having ever heard of Mr. Cavendish drawing the same conclusion. The improbability must also be admitted to be extreme, of Sir Charles Blagden ever having heard of Mr. Cavendish's theory prior to the date of Mr. Watt's letter, and not mention- ing that circumstance in the insertion which he made in Mr. Cavendish's paper. * That the idea existed in his mind previously, is proved by his declarations to Dr. Priestley, cited by the latter ; by his own asser- tions, p. 335 of his paper ; and by the existing copies of his letters in December 1782.-— [NOTE BY MB. JAMES WATT.] 400 WATT. It deserves to be farther mentioned, that Mr. "Watt left the correction of the press, and every thing relating to the publishing of his paper, to Sir Charles Blagden. A letter remains from him to that effect, written to Sir Charles Blag- den, and Mr. Watt never saw the paper until it was printed. Since M.

Arago, for he has kindly spared me ; and while I ex- press my obligations for this courtesy of my reverend, learned, and valued friend, I must express my unqualified admiration of his boldness in singling out for his antagonist my illustrious colleague, rather than the far weaker combatant against whom he might so much more safely have done battle. Whatever might have been his fate had he taken the more prudent course, I must fairly say (even without waiting until my fellow champion seal our adversary's doom), that I have seldom seen any two parties more unequally matched, or any disputation in which the victory was so complete. The attack on M. Arago might have passed well enough at a popular meeting at Bir- mingham, before which it was spoken; but as a scientific inquirer, it would be a flattery running the risk of seeming ironical to weigh the reverend author against the most eminent philo- sopher of the day, although upon a question of evidence (which this really is, as well as a scientific discussion) I might be content to succumb before him. As a strange notion, how- ever, seems to pervade this paper, that everything depends on the character of Mr. Cavendish, it may be as well to repeat the disclaimer already very distinctly made of all intention to cast the slightest doubt upon that great man's perfect good faith in the whole affair ; I never having supposed that he borrowed from Mr. Watt, though M. Arago, Professor Robison,* and Sir H. Davy, as well as myself, have always * Encyc. Brit., vol. xviii., p. 808.

It is also said by Mr. Harcourt that the late Dr. Henry having examined Mr. Watt's manu- scripts decided against his priority. I have Dr. H.'s letter before me of June, 1820, stating most clearly, most fully, and most directly, the reverse, and deciding in Mr. Watt's favour. I must add, having read the full publication with fac-similes, Mr. Harcourt has now clearly proved one thing, and it is really of some importance. He has made it appear that in all Mr. Cavendish's diaries and notes of his experiments, not an intimation occurs of the composition of water having been in- ferred by him from those experiments earlier than Mr. Watt's paper of spring, 1783. 2 D ( 402 ) PRIESTLEY. MENTION has already been more than once made of Dr. Priestley ; and certainly history would imperfectly perform its office of recording the progress of natural knowledge should it pass over his important discoveries without the large share of attention and of praise which they are well entitled to claim. In turning, however, to recount the events of his life, we make a somewhat painful transition from contemplating in its perfection the philosophic character, to follow the course of one who united in his own person the part of the experi- mental inquirer after physical truth with that of the angry polemic and the fiery politician, leading some- times the life of a sage, though never perhaps free from rooted and perverted prejudice — sometimes that of a zealot against received creeds and established in- stitutions, and in consequence of his intemperance, alternately the exciter and the victim of persecution. Nevertheless, the services which he rendered in the former and better capacity, ought to be held in grate- ful remembrance by the cultivators of physical science. Nor are we to suppose that even in his polemical ca- pacity he was not in pursuit of truth. He may have had a tendency to oppose established opinions ; a disposition which led him, as he says himself, at the by W. Soil. efo Q^?;/5^^/G>^;;^^^^^^^^^// f '^•w/sSr. PRIESTLEY. 403 age of twenty "to embrace what is generally called the heterodox side of every question,"* just as he had a disposition pertinaciously to keep by the received and erroneous chemical theory ; but if he thought for him- self, and followed the bent of his convictions, we have no right to doubt his conscientious motives, the more especially as his heterodox dogmas, always manfully avowed, never brought him anything but vexation and positive injury in his temporal concerns. The perti- nacity with which he defended to the end of his days the chemical doctrine of Phlogiston, and the equal zeal with which he attacked the theological tenets of original sin and the atonement, alike proceeded from sincere conviction, and no one has a right to blame him for either of these opinions, even if it be quite clear that he was wrong in both. Joseph Priestley was the son of a cloth- dresser at Birstal-Fieldhead, near Leeds, and was born there loth of March (old style), 1733. His family appear to have been in humble circumstances ; and he was taken off their hands after the death of his mother by his paternal aunt, with whom he went to live when nine years old, ai)d who sent him to a free school at Batley, in the neighbourhood. There he learnt something of Greek and J^atin, and a dissenting minister taught him a little Hebrew in the vacation of the grammar- school. To this he adcled some knowledge of other East- ern languages connected with Biblical literature ; he made a considerable progress in Syriac and Chaldean, and began to learn Arabic ; he also had a little instruc- tion in the mathematics from a teacher who had been * Works.— Memoirs, vol. i. part i. p. 25. 2D 2 404 PRIESTLEY. educated under Maclaurin, at Edinburgh. But in this science he made very little proficiency.* Indeed his whole education was exceedingly imperfect, and excepting in Hebrew and in Greek he never afterwards improved it by any systematic course of study ; but in both these languages he became well versed, and especially used always to read the Scriptures in the original tongues. Even in chemistry, which of the sciences he best knew and in which he made so important a figure, he was only half taught ; and he himself acknowledged, after having failed to obtain a chemical lectureship, that he " never could have acquitted himself properly in it, never having given much attention to the common routine of the science, and knowing but little of the common processes." — ' ' When I began my experiments," he says, " I knew very little of chemistry, and had in a manner no idea of the subject before I attended a course of lectures at an academy where I taught." So that he was not well-informed, and had never studied either the theoretical or the practical parts of it, but just got possession of such portions of the subject as occasionally came within the scope of the experiments he was making, and the doctrines he was discussing at the time. His whole writings, which are numberless, and without method, or system, or closeness, or indeed clearness, bear ample testimony to what we might ex- pect would be the result of so very imperfect a found - * This is manifest from several parts of his writings, although he in one passage of his correspondence speaks of having once been very fond of the study ; for in th.e same paper he speaks of Baron Maseres' work (' Scriptores Logarithm] ci') as if he had been the author, instead of the collector. — Mem. i. part ii. p. 490. PRIESTLEY. 405 ation as his scanty and rambling education had laid. That education, however, far from redounding to his discredit, very greatly enhances the merit of the man. He presents one of the memorable examples of know- ledge pursued, science cultivated, and even its bounds extended, by those whose circumstances made their ex- ertions a continued struggle against difficulties which only virtue and genius like theirs could have overcome. He went to study for some years at the dissenting academy founded by Mr. Coward, at Daventry, and since transferred to London, where it is in a kind of union, mutually beneficial, with the University Col- lege. Mr. Ash worth had succeeded the learned and pious Dr. Doddridge as its principal teacher, and under him Priestley remained till 1755. During the three years that he studied here, he and his intimate friends used to make a point of reading, daily, ten pages of Greek, and every week one Greek play, a practice which they continued after they left the school, corre- sponding with each other on the subject of their studies. On quitting Daventry, having taken orders, he was appointed minister of a congregation at Needham Mar- ket, in Suffolk. He had been brought up by his father and aunt in the strictest Calvinistic principles, most of which he very soon from conviction abandoned ; and so early did his spirit of free inquiry show itself, that having before he left his aunt's house desired to be admitted as a communicant at the chapel which she attended, he was rejected by the minister on his prepa- ratory examination, in consequence of doubts expressed respecting original sin, and eternal damnation as its punishment. He describes the deep distress into which 406 PRIESTLEY. he was thrown by feeling that he was unable to ex- perience due contrition and repentance for Adam's fault ; and the rigid divine who tested the state of his mind on this point, withheld the sacred ordinances in consequence. At Needham his salary did not exceed thirty pounds, indeed it seldom amounted to so much, and he could only subsist by the aid which certain dis- senting charities afforded to augment this poor stipend. His predecessor, Dr. Doddridge, had never received above thirty-five pounds a-year, and his board then (1723) only cost him ten pounds. Priestley's opinions proved distasteful to the congregation, who probably regarded the eternity of hell-torments as a peculiar pri- vilege rudely invaded by him ; and he removed in 1758 to Nantwich, in Cheshire, where he obtained some thirty pupils, beside a few young ladies and a private tutorship in an attorney's family. This increased his income, and enabled him, by means of the strictest frugality, to purchase a scanty apparatus ; for he had now added a little natural philosophy to his favourite theological studies, the fruit of which had been already two works, one of them against the atonement. I say a little natural philosophy ; for he confesses that when nine years later he began to write his ' History of Electricity,' he was but imperfectly acquainted with the subject. It is a careless and superficial work, hastily written, as is his ' History of Vision ;' and the original experiments afforded no new information of any value. In 1761 he removed to Warrington Academy, in which he succeeded Dr. Aikin as tutor in the belles lettres. On settling at Warrington he married the daughter of Mr. Wilkinson, a respectable iron master in Wales. PRIESTLEY. 407 She was an amiable woman, and endowed with great strength of mind, which was destined afterwards to be severely tried. By her he had several children, one of whom survived them both. He appears to have chiefly devoted himself to theo- logical studies, and hence the great disproportion which his Hebrew and Greek learning bears to his other ac- quirements. Metaphysical speculations, next to these, engaged his attention ; and the influence produced in his mind, and even his conduct, by Dr. Hartley's cele- brated work ('Observations on Man'), has been re- corded by himself. " I hardly know," he says, " whether it more enlightens the understanding or improves the heart." He says he also had studied com- position, and mainly by the help of writing poetry, of no merit, but according to him the best means of learning to write good prose. That his taste, however, was some- what deficient in this respect we may fairly affirm, when we find him pronouncing, many years after, a decided opinion that Belsham's ' History' is written in a better style than Robertson's or Hume's.* The universality of his attempts may be judged from his delivering at Warrington a course of lectures on ana- tomy. He sought relaxation from music, and learnt to play on the flute. He strongly recommends this to students, especially, he says with some naivete, such as have no fine ear, " for they will be the less annoyed by bad music." As early as during his education at Daventry he had written a work which, however, was not published till twenty years later ; it was the ' Institutes of * Mem. and Cor. 1796, vol. i. part ii. p. 358. 408 PRIESTLEY. Natural and Revealed Religion/ But having once begun to publish in 1761, his appeals to the press were incessant, and on almost every subject. A ' Theory of Language,' books on ' Oratory and Criticism/ on ' History and General Policy/ on the ' Constitution and Laws of England,' on ' Education,' a ' Chart of Bio- graphy,' a ' Chart of History ;' these and others were all written while he resided at Warrington, from 1761 to 1769. How well he was qualified to write on oratory and on English law, we may easily conjecture, from the circumstance that he could never have heard any speaking save in the pulpits of meeting-houses, and in all probability had never seen a cause tried ; but even if he had been present at debates and trials, it is difficult to imagine anything more adventurous than the tutor of an academy, afflicted with an incurable stutter, and who devoted his time to teaching and to theology, pro- mulgating rules of eloquence and of jurisprudence to the senators and lawyers of his country. That we may come without interruption to his really useful studies, it may be well here to take notice of his other contro- versial writings. In consequence of a disagreement with the Warrington trustees in 1767 he removed to Leeds, where he became minister of the Mill-Hill chapel, and wrote many controversial books and pamphlets In after times he wrote 'Letters to a Philosophical Institution;' ' An Answer to Gibbon;' 'Disquisitions on Matter and Spirit ;' ' Corruptions of Christianity ;' ' Early Opinions on Christ ;' ' Familiar Letters to the Inhabitants of Birmingham ;' ' Two Different Histo- ries of the Christian Church ;' ' On Education ;' ' Com- parison of Heathen and Christian Philosophy ;' ' Doc- PRIESTLEY. 409 trine of Necessity ;' * On the Roman Catholic Claims ;' * On the French Revolution ;' ' On the American War ;' beside twenty volumes of tracts in favour of the Dissenters and their rights. His general works fill twenty-five volumes,* of which only five or six are on scientific subjects : his publications being in all one hundred and forty-one (in one year ten), of which only seventeen are on scientific matters. He is one of the most voluminous writers of any age or country, and probably he is of all voluminous writers the one who has the fewest readers. This arises from the circum- stance that, though his political opinions are shared by many, the bulk of his works are theological and metaphysical, but especially theological ; and his re- ligious opinions were confined to an extremely small class of persons. Indeed it may be questioned if he was not in several respects the only person who held his peculiar faith upon all points. It happened, fortunately, that when he went to reside at Leeds in care of the Mill-Hill Chapel, his house immediately adjoined a common brewery, and this led him to make experiments upon the fixed air copiously produced during the process of ferment- ation. It must be observed, that long before this time the great step had been made by Black, of ascertaining that there are other permanently elastic fluids than our atmosphere, and which have properties wholly different from it. Cavendish, too, had very recently subjected both fixed and inflammable airs (carbonic acid and * Edited by the affectionate care of an able and worthy man, Mr. Towell Rutt. 410 PllIESTLEY. hydrogen gases) to accurate experiments, showing their relative specific gravities, and proving that they were of the same nature from what bodies soever they were obtained. The probability was, that other gaseous fluids existed in nature as well as those two and common air. The experimenter had, therefore, thenceforth, his attention directed to meeting with these: and an examination of all the products of mixture and of heat, by precipitation or evaporation, was now the natural course of experimental inquiry. At first, Priestley only tried in what way fixed air could be most easily combined with water ; he pub- lished in 1772 a pamphlet upon the means of effecting this union, and the condensing process which he employed is used to this day. He soon after gave to the Royal Society his observations on different kinds of air, which ascertained the important fact, that at- mospheric air, after having been corrupted by the re- spiration of animals or by the burning of inflammable bodies, is restored to salubrity by the vegetation of plants ; and that if the air is exposed to a mixture of sulphur and iron filings, as in one of Hales's experi- ments, its bulk is diminished between a fourth and u fifth, and the residue is both lighter than common air and unfit to support life. This residue he called 1 Phlogistic air ;' afterwards it was called ' Azotic ' or ' Nitrogen gas ;' and Dr. Rutherford, of Edinburgh, as well as Priestley, though unknown to each other, discovered it about the same time. For these experi- ments the Copley Medal was, in 1773, justly awarded to him by the Royal Society. The following year was destined to be the period PRIESTLEY. 411 of a discovery most important for science, and truly glorious for its author. Having exposed red-lead, or minium, in a close vessel to the sun's rays concentrated by a burning-glass, he found that an aeriform body, permanently elastic, was evolved, and that this air had the peculiar property of increasing exceedingly the intensity of flame. This gas he called ' dephlogisticated air/ upon the principle that the matter of heat and light, the phlogiston of Stahl, being abstracted from it by the return of the calx to its metallic state, which phlogiston was supposed by that theory to effect, the air had great avidity for phlogiston, and seized it from the inflammable bodies it came in contact with. This most important discovery, which he thus con- nected with an erroneous theory, was made on the 1st of August, 1774. He afterwards discovered that its absorption by the lungs in the process of respiration gives its red colour to arterial blood, as it was proved to act through the substance of thin bladder ; and he found that when plants grow in close vessels, and restore the purity of the air in which a candle has burnt or an animal breathed, they do so by evolving this pure air. The new nomenclature gave it the name of c oxygen gas/ from the belief then generally entertained that it was the acidifying principle. Later experiments have proved that there is at least one great exception to this in chlorine, formerly called 'oxy- genated muriatic acid ;' but now found to be wholly without oxygen, and yet to have all the properties of an acid. But, indeed, water itself, and the atmo- spheric air, having neither of them the nature of acids, are both contrary to the theory ; and the fixed alkalis 412 PRIESTLEY. are found to owe their alkaline state and lose their metallic, like other oxides, by uniting with oxygen. Priestley is the undoubted discoverer of oxygen. He was the first who communicated a knowledge of it to Lavoisier, at Paris, soon after he had made the dis- covery ; nor can anything be more disingenuous than that celebrated person's afterwards affirming that he, Priestley, and Scheele, had all discovered it " about the same time." He never discovered it until Priestley discovered it to him. Bergmann's suppressing in his book all knowledge of the experiments of Black and Cavendish, the former published twenty and the latter eight years before, was bad enough, but not equal to Lavoisier's positive assertion contrary to what must have been his positive knowledge. This great discovery was far from being the last of its justly celebrated author. He discovered the gases of muriatic, of sulphuric, and of fluoric acids, ammonial gas, and nitrous oxide gas. He also dis- covered the combination which nitrous gas forms suddenly with oxygen; diminishing the volume of both in proportion to that combination ; and he thus invented the method of eudiometry, or the ascertain- ment of the relative purity of different kinds of atmo- spheric air. It must not be forgotten, in considering the great merits of Priestley as an experimentalist, that he had almost to create the apparatus by which his processes were to be performed. He, for the most part, had to construct his instruments with his own hands, or if he employed others, he had to make unskilful work- men form them under his own immediate direction. PRIESTLEY. 413 His apparatus, however, and his contrivances for col- lecting, keeping, transferring gaseous bodies, and for exposing substances to their action, were simple and effectual, and they continue to be still used by chemical philosophers without any material improvement. It was fortunate in this respect that he began his pneu- matic inquiries with seeking for the means of im- pregnating water with carbonic acid ; this inquiry naturally turned his attention to the contrivance of apparatus and generally of manipulations, serviceable in the examination of bodies whose invisible form and elastic state renders inapplicable to them the machi- nery of the old laboratory, calculated only for solids and liquids. The pertinacity with which Priestley clung to the phlogistic theory is marvellous. It might have been expected, that the fact of a combustion leaving the residue, whether of two gases, or of a gas and an in- flammable body, exactly equal in weight to the sum of the weights of the bodies burnt and which had disap- peared in the process, would have been accepted as a proof that these two bodies had entered into an union, giving out the latent heat which had previously held the gaseous body or bodies in a state of aeriform fluidity. It might, in like manner, have been ex- pected, that when a metal, by absorbing oxygen gas, becomes calcined, and gains in weight precisely the weight of the gas which has disappeared, the calcination should be ascribed to the gas, and that the reproduction of the gas by heat, or by its abstraction by electric affinity for some other body, should be allowed to restore the metallic state by simply severing that 414 PRIESTLEY. union of the gas and the metal which had changed it. But nothing could overcome Priestley's repugnance to give up phlogiston : he adhered to it while he lived ; he never would believe that water was formed of the two gaseous bodies whose combustion and disappear- ance leaves a weight of liquid equal to their joint weights ; he always imagined that water was held in suspense by these gases and precipitated on their disappearing. He never would believe that metals owe their malleability and lustre to any cause other than phlogiston, or lose their properties except by combining with oxygen, which takes the phlogiston from them. He never would believe that combustion is anything but the phlogiston leaving the inflammable body and joining the oxygen ; or that when an acid is formed by the burning, that acid contains the oxygen and the combustible base. That his obstinate unbelief was perfectly disinterested no one can doubt. The discoverer of oxygen, and of the true cause of re- spiration, had, of all men, the strongest interest in assenting to a theory which was wholly founded upon his own discovery, and which made him the imme- diate, as Black was the more remote, author of modern chemical science — made him the philosopher who had raised the superstructure upon the foundation which his predecessor had laid. The merit of Dr. Priestley, as a cultivator of science, was the activity with which he made experiments — the watchful attention with which he observed every phenomenon, following the minutest circumstances of each process — the versatility with which he prosecuted each new idea that arose from his trials — his diligence PRIESTLEY. 415 in recording all the particulars, as if well aware how much depends in every branch of inductive philosophy upon allowing no fact to escape, when we are con- fessedly in search of light, and can never tell how any given fact may bear on the unknown conclusion to which our analytical process is leading us. As a reasoner his powers were far less considerable. He possessed not the sound judgment, the large circum- spection, which enables men to weigh the relative value of either reasons or facts. He was cautious enough and drew little from his imagination in feigning hypotheses, if it be not the reasons which he invented from time to time for the purpose of sustaining the desperate fortunes of the phlogistic theory, and making the facts bend to it as they successively arose with a force capable of shivering it in pieces. But he was also deficient in the happy sagacity which pierces through apparent dissimilarity, and ranges things apparently unlike under the same class — he had not that chas- tened imagination which can see beyond the fact present to the senses — in a word, he was much greater as a collector of new facts than a reasoner upon them — and his inductive capacity was inferior to his power of ex* perimenting and of contriving the means of observation. Perhaps his want of general scientific acquirements, and his confined knowledge of chemistry, itself contri- buted to the activity and the boldness with which he performed novel experiments, while the same defect impaired his capacity as an inductive philosopher. It is extremely probable that the strict attention to prin- ciple, the methodical systematic spirit which prevailed over the inquiries of Black and of Cavendish — the 416 PRIESTLEY. scientific views which directed the contrivance of all their processes, never leading them to make any trial without some definite object in view., prevented them from performing many experiments, — from stooping, as it were, to try things which Priestley did not disdain to try from his more empirical turn of mind — what Mr. Watt, in a letter, calls "his random haphazarding." In 1779, when Captain Cook was preparing to sail upon his second voyage, Mr. Banks, who took a great interest in it from having been engaged in the first, invited Dr. Priestley to accompany the Captain as as- tronomer to the expedition. Advantageous terms were proposed, including a provision for his family. He entertained the proposal, and then agreed to it ; but objections were taken by the clerical members of the Board of Longitude, not to his ignorance of astronomy and of natural history, but to his Socinian principles in religion, which one might have supposed could exer- cise but a limited influence upon his observations of the stars and of plants. I know not if the same scientific authorities objected, on like grounds, in the council of the Royal Society, to receiving papers upon his chemical discoveries. It is certain that a like in- fluence prevented Professor Playfair from afterwards proceeding to India, where he had designed to prosecute his inquiries into the science of the Hindoos. Such passages stamp the history of a great nation with indelible infamy in the eyes of the whole world. In 1773, when his fame had been established by his first discoveries, and the Royal Society had crowned his paper with their medal, Priestley accepted an invita- tion from Lord Shelburne, afterwards first Marquis of PRIESTLEY. 417 Lansdowne, to fill the place of librarian and philoso- phic companion, with a salary of 250/., reducible to 150/. for life should he quit the employment. An additional allowance of 40 /. a-year was given by this truly munificent patron for the expense of apparatus and experiments ; homes were provided for his family in the neighbourhood both of Lord Shelburne's town and country residence ; nor can anything be easily conceired more truly gratifying to a man of right feelings, and of a noble ambition, than the reflection must have been, that the discovery of oxygen was made under his roof, and with the funds which his disin- terested liberality had provided for his philosophic guest. With whatever difference of sentiments states- men may at any time view Lansdowne House, the lovers of science to the latest ages will gaze with veneration on that magnificent pile, careless of its architectural beauties, but grateful for the light which its illustrious founder caused to beam from thence over the whole range of natural knowledge ; and after the structure shall have yielded to the fate of all human works, the ground on which it once stood, consecrated to far other recollections than those of conquest or of power, will be visited by the pilgrim of philosophy with a deeper fervour than any that fills the bosom near the forum or the capitol of ancient Rome. In 1780 Priestley settled at Birmingham, where he was chosen minister of the principal Dissenting con- gregation. He had left Lansdowne House without any difference to interrupt the friendship of its inmates ; and some years afterwards an offer to return, made on the death of Lord Lansdowne's friends, Dunning and 2 E 418 PRIESTLEY. Lee, was declined.* A subscription among his friends furnished the means of prosecuting his experimental researches ; and he declined an offer to obtain for him a pension from the Government. A shade is cast upon this passage of his history by the circumstance of the pecuniary aid which he thus received being only in a small part rendered necessary for his experimental pur- suits. Mr. Parker, the eminent optician, furnished him for nothing all the instruments made by him, as did Mr. Wedgwood all his earthenware utensils. Yet we find in his correspondence a painful thankfulness expressed, in any thing rather than the language of a philosopher, to Mrs. Rayner and Mr. Lee, for " seasonable benefactions." The "apology" which he evidently feels required for this kind of dependence is not at all confined to the " ex- pense of his philosophical and theological studies ;" he refers also to the education of his children, and to the expenses of housekeeping occasioned by his reputation. f It is not invidious to observe that, be a man's celebrity ever so great, he is not bound to incur any expenses in keeping hospitality, if these, " exceeding twice his own income" (and that, with the pension of Lord Lans- downe, not an inconsiderable one), can only be met by the large " benefactions" of his friends. He names fifteen who gave him by subscription a yearly allow- ance, all the while he chose to decline an offer made to * This offer, and Lord Lansdowne's frank declaration that he never had any fault to find with his guest, entitles us to state that no quarrel, nor anything like it, had occurred. Nevertheless Priest- ley's offer to visit his Lordship when he occasionally came to London was politely declined. Political reasons apparently caused this refusal. f Memoirs, vol. L, part i., page 217. PRIESTLEY. 419 procure a pension from the Government, " wishing to preserve himself independent of every thing connected with the Court." We must on this be content to remark, that different men entertain different notions of independence. Settled at Birmingham, he continued, however, his controversial writings, and engaged eagerly in conflict with Gibbon upon his celebrated chapters respecting the Early History of Christianity, and with Bishop Horsley upon the Socinian doctrines. In the latter controversy the Episcopal and the Sectarian tempe- rature, both high, were not very unequal ; but in the former the minister of the Gospel had all the heat to himself — at least in the layman it was latent, if it existed at all. He was desirous of drawing his adversary into a controversy, and, failing in this, lost his temper, and had the vulgar recourse to calling names and imputing motives. Mr. Gibbon may have shown some superciliousness in his treatment of this angry polemic ; but he certainly had a good right to marvel at the intolerance of one whose heterodoxy was so universal as to "condemn by circumscribing the inspiration of the Evangelists, and to condemn the reli- gion of every Christian nation as a fable less innocent, not less absurd, than Mahomet's journey to the third heaven." How fortunate it was that Priestley lived in an age when the use of actual fire is withheld from theological disputants, as a mode of argumentation, must appear from the wonder he expresses at David Hume's monument having been so long suffered to offend the pious eyes of the Edinburgh people — an ex- pression which might seem to convey a hint that he 2 E 2 420 PRIESTLEY. would have taken care to avoid, after lie had himself felt the weight of the popular hand when called in to settle theological disputes. Having taken, as was his wont, an active but not a very temperate part in the controversy to which the French Revolution gave rise, and having published a ' Reply' to Mr. Burke' s famous pamphlet, he was early in 1791 made a citizen of the French Republic. An ironical and somewhat bitter pamphlet against the high church party still further excited the feelings of the people against him ; and a dinner being given on the 14th of July to celebrate the anniversary of the attack upon the Bastille, the mob attacked the tavern where the party were assembled, Dr . Priestley was not present, but his chapel and house were immediately after assailed. His library, manuscripts, and apparatus were destroyed ; his person and his family escaped. The compensation which he ob- tained, by an action against the hundred, fell short, according to his own account, by 2000/. of his loss. As, however, an ample subscription was made for him, and as his brother-in-law generously gave him 10,000/., with an annuity of 200/. for life, he could not be other than a large gainer by the execrable violence of which he had been the victim ; and as he never allowed any of his writings to remain unpublished for even the shortest time after they were finished, it is not likely that any loss of an irreparable kind was incurred by the burning of his papers. He found, however, that he could no longer reside with comfort in the scene of such outrageous proceedings, and among a community which had so shamefully countenanced PRIESTLEY. 421 them. He removed to London, and succeeded his friend, Dr. Price, as Principal of the Hackney Academy. Late in the month of September, 1792, he was elected by the department of the Orne a member of the National Convention, about to assemble after the subversion of the French monarchy. This singular honour bestowed on him, as well for his philosophical fame as for his political services and the persecutions to which they had exposed him, he re- spectfully declined, giving as his reason that he was not familiar with the French language, and had not devoted his time sufficiently to legislative duties. But this moderation disarmed not his enemies — he was pur- sued by the intolerant spirit of the times. He found himself shunned by his former associates in science. Even the Royal Society did not afford an exception to this persecuting loyalty, or a shelter from its effects ; and in the spring of 1794 he withdrew to America. Here he again suffered considerable disappointment. His religion was too much for those who had ceased to care for sacred things, and far too scanty for those who still were Christians, while his republican opinions were exceedingly distasteful because they were tinged with a decided admiration of France. He continued, however, to inhabit the country, and to prosecute his studies, chiefly theological. He received contributions regularly from his benefactors in England, Mrs. Rayner and the Duke of Grafton ; but these, though acknow- ledged by him in the same unpleasant style as eleemo- synary (" very acceptable benevolences"), were for the most part on a different footing from the English 422 PRIESTLEY. charities ; they appear generally to have been required for the propagation of their Unitarian opinions, to which the parties were all so zealously attached. He settled at Northumberland, in an uncleared dis- trict, where he purchased three hundred acres of land ; and his youngest son, Henry, then a very fine young man of eighteen, devoted himself to the clearing and culti- vating this woodland spot, working with his labourers and sharing their toils. The father himself partook of this labour for two or three hours daily. On Sun- days he frequently preached, and when he visited Philadelphia he always did so. He devoted the rest of his time to his works, particularly his ' Church History ;' and he wrote answers to Paine and Volney. He was much obstructed in his philosophical pursuits by the want of proper accommodation for his apparatus, and he only wrote three tracts on chemical subjects during the ten years of his residence in America ; two of which were merely arguments on phlogiston, and the third alone had any experiments, written eight years before his death. At the end of 1795 he suffered a heavy affliction in the death of his son Henry, after a few days' illness ; and in ten months more he also lost his wife. These blows, though he felt their weight, did not at all crush him ; his resignation was exemplary ; and his steady, enthusiastic faith in Revelation gave him a cer- tain hope of meeting before many years should elapse with those whom he had lost. Indeed, his letters clearly show that he regarded the sundering of these ties far less attentively than their restoration. A few PEIESTLEY. 423 days after his son's death he writes to his most inti- mate friend and constant correspondent, Theophilus Lindsay, recounting the particulars of his loss, and he adds that he is composing three discourses on Revela- tion against modern unbelievers. The letter next year announcing his wife's death, begins with saying to the same friend how much he stands in need of his sym- pathy, and goes on to add, " This day I bury my wife ; she died on Saturday after an illness of a fortnight." He adds some remarks on his literary occupations, and concludes with mentioning a plan he has of travelling to distract his mind.* No one who reads his letters and memoirs by himself can doubt that this stoical firmness is not the result of a callous disposition, but the signal triumph of a heartfelt belief in the promises of Religion over the weakness of our nature. It is, indeed, quite manifest that Religion was as much an active principle in him as in any one who ever lived. Not only is it always uppermost in his thoughts, but he even regards temporal concerns of a public nature always in connexion with the Divine superintendence, and even with the prophecies of Scripture. His letters are full of references to those prophecies as bearing on passing events, and he plainly says that since his removal to America he should care little for European events but for their connexion with the Old Testament. He also looked for an actual and material second coming of Christ upon earth. It is not true to affirm that he was little of a poli- ., vol. i. part ii. p. 328, 354. 424 PRIESTLEY. tician, though in declining the seat in the National Convention he says* his studies had been little directed towards legislation compared with theology and philo- sophy; and denies in a letter to William Smith that he ever taught or even mentioned politics to his pupils, as he had been charged with doing, among the innu- merable falsehoods of which he was the subject. Nor is the circumstance of his not attending political meet- ings at all decisive of his being little of a political agi- tator, because his incurable stutter prevented him from taking a part in such proceedings. But he wrote in 1774, at Franklin's request, an address to the people on the American disputes, previous to the general election. He answered Mr. Burke's * Reflections on the French Revolution.' He mixed in the question of the Catholic claims ; and he published in all no less than eleven political works, almost every one upon the topics of the day. It is equally true, however, that theological controversy occupied him far more con- stantly and engaged his mind far more deeply than political matters ; that he was regularly a theologian and incidentally a partisan. The cast of his political opinions was originally little more tending to democracy than those of Whigs usually are who have read and discussed more than they have reflected and seen. He used, indeed, to say that in politics he was a Trinitarian, though a Unitarian in religion. It must, however, be confessed that he went very much further in the same direction after the French Revolution had set fire to the four * Mem., vol. i. part ii. p. 190—198. PRIESTLEY. 425 quarters of the political world, and his admiration of republican principles might be measured by his zeal for the innovators of France, with the success of whose arms he deemed the safety of freedom to be bound up- When we read his answer to the offer of a seat in 1792, and reflect that it was penned about three weeks after the horrible massacres of September, the worst of the atrocities which disfigured the Revolution, it moves our wonder to find a Christian minister accompanying his acknowledgment of the honour proposed, that of being enrolled among the authors of the tragedy so recently enacted, with no protest against the bloody course then pursuing, no exception to the unquali- fied admiration expressed of the youthful republic. In America we find his leanings are all against the Federal party, and his censures of the great Chief of the Union little concealed. He felt for the demo- cratic party, the French alliance, the enemies of Eng- lish partialities, and he regarded Washington as un- grateful because he would not, from a recollection of the services of France twenty years before to American independence, consent to make America dependent upon France. The indifferent reception which he met with in society was probably owing to this party vio- lence full as much as to the dislike of his Unitarian opinions. But it must be added, that his temper was so mild, and his manners so gentle, as to disarm his most prejudiced adversaries whensoever they came into his society. Many instances of this are given in his correspondence, of which one may be cited. Pie hap- pened to visit a friend whose wife received him in her husband's absence, but feared to name him before a Cal- 426 PRIESTLEY. vinistic divine present. By accident his name was men- tioned, and the lady then introduced him. But he of the Genevan school drew back, saying, " Dr. Joseph Priestley ?" and then added in the American tongue, *' I cannot be cordial." Whereupon the Doctor, with his usual placid demeanour, said that he and the lady might be allowed to converse until their host should return. By degrees the conversation became general ; the repudiator was won over by curiosity first, then by gratification; he remained till a late hour hanging upon Priestley's lips ; he took his departure at length, and told the host as he quitted the house, that never had he passed so delightful an evening, though he ad- mitted that he had begun it " by behaving like a fool and a brute." One such anecdote (and there are many current) is of more force to describe its subject than a hundred laboured panegyrics. After the loss of his wife and his younger and favourite son, he continued with unabated zeal to pursue his theological studies, and published several works, both controversial and historical, beside leaving some which have been given to the world since his decease. He endeavoured, too, as far as he could, to propagate the tenets of Unitarianism, and to collect and extend a congregation at Philadelphia attached to that doctrine. At one time, in the sum- mer of 1797, entertaining hopes of peace in Europe, he had resolved to visit France, where he might communicate personally with his English friends ; and he even thought of making a purchase in that country on which he might reside during a part of each year. So nearly did he contemplate this removal, that we PRIESTLEY. 427 find him desiring the answers to letters he was writing might be sent to the care of Messrs. Perregaux at Paris. The revolution of Fructidor, however (4th September, 1797), put an end to all prospects of peace, and the war soon raged in every quarter with re- doubled fury. He seems now to have derived his chief comfort from tracing the fancied resemblance between the events passing before him and the prophecies in Scripture ; though occasionally he felt much puzzled, and the book of Daniel, especially, appears to have given him trouble and perplexity. When the peace came at last, his health was too much broken to permit any plans to be executed such as he had four years before contemplated. In 1802 he became a confirmed invalid, suffer- ing from internal, and apparently organic, derange- ment. His illness was long and lingering, and he suffered great pain with perfect patience for two years. The prospect of death which he had before him did not relax his application to literary labour, his faculties remaining entire to the last. Neither did that awful certainty, ever present to his mind, affect him with sorrow or dismay. The same unshaken belief in a future state, the same confident hope of immortal life which had supported him under his affliction for the death of others, cheered him while contemplating the approach of his own. In this happy frame of mind he gently expired on the 6th of February, 1804, in the seventy-second year of his age. His character is a matter of no doubt, and it is of a high order. That he was a most able, most indus- trious, most successful student of nature, is clear ; and 428 PRIESTLEY. that his name will for ever be held in grateful remem- brance by all who cultivate physical science, and placed among its most eminent masters, is unques- tionable. That he was a perfectly conscientious man in all the opinions which he embraced, and sincere in all he published respecting other subjects, appears equally beyond dispute. He was, also, upright and honourable in all his dealings, and justly beloved by his family and friends as a man spotless in all the relations of life. That he was governed in his public conduct by a temper too hot and irritable to be con- sistent either with his own dignity, or with an amiable deportment, may be freely admitted ; and his want of self-command, and want of judgment in the practical affairs of life, was manifest above all in his controversial history ; for he can be charged with no want of pru- dence in the management of his private concerns. His violence and irritability, too, seems equally to have been confined to his public life, for in private all have allowed him the praise of a mild and attractive demeanour; and we have just seen its great power in disarming the prejudices of his adversaries. ( 429 ) CAVENDISH. A GREATER contrast between two men of science, both eminent benefactors to the same branch of know- ledge, can hardly be imagined than Cavendish offers to Priestley. He was thoroughly educated in all branches of the Mathematics and Natural Philosophy ; he studied each systematically ; he lived retired from the world among his books and his instruments, never meddling with the affairs of active life ; he passed his whole time in storing his mind with the knowledge im- parted by former inquirers and in extending its bounds. Cultivating science for its own sake, he was slow to appear before the world as an author ; had reached the middle age of life before he gave any work to the press ; and though he reached the term of four- score, never published a hundred pages. His methods of investigation were nearly as opposite as this diversity might lead us to expect ; and in all the accidental circumstances of rank and wealth the same contrast is to be remarked. He was a duke's grandson ; he possessed a princely fortune ; his whole expenditure was on philosophical pursuits ; his whole existence was in his laboratory or his library. If such a life presents little variety and few incidents to the vulgar observer, it is a matter of most interesting con- templation to all who set its just value upon the cultivation of science, who reckon its successful pur- 430 CAVENDISH. suit as the greatest privilege, the brightest glory of our nature. Henry Cavendish was born at Nice, whither his mother's health had carried her, the 10th of October, 1731. He was the son of Lord Charles Cavendish, the last Duke of Devonshire's great uncle, by the daughter of Henry Grey, Duke of Kent. His family, aware of the talents which he early showed, were anxious that he should take the part in public life which men of his rank are wont to do, and were much displeased with his steady refusal to quit the studies which he loved. An uncle, disapproving of the course pursued towards him, made him his heir ; and so ample a fortune came into his possession that he left at his death a million and a quarter of money.* The Mathematics, and the various branches of Natural Philosophy, were the chief subjects of his study, and of all these sciences he was a consummate master. The discoveries of Black on carbonic acid and latent heat, appear to have drawn his attention to the cultivation of pneumatic chemistry ; and in 1766 he communicated to the Royal Society his experiments for ascertaining the properties of carbonic acid and hydrogen gas.f He carried his mathematical habits into the laboratory ; and not satisfied with showing the other qualities which make it clear that these two * M. Biot's article in the Biog.

Such errors seem incredible. f Three papers containing experiments on factitious air. Phil. Trans., 1766, p. 141. CAVENDISH. 431 aeriform substances are each sui generis, and the same from whatever substances, by whatever pro- cesses, they are obtained ; nor satisfied with the mere fact that one of them is heavier, and the other much lighter, than atmospheric air, — he inquired into the precise numerical relation of their specific gravities with one another and with common air, and first showed an example of weighing permanently elastic fluids : unless, indeed, Torricelli may be said before him to have shown the relative weight of a column of air and a column of mercury : or the common pump to have long ago compared in this respect air with water. It is, however, sufficiently clear, that neither of these experiments gave the relative measure of one air with another : nor, indeed, could they be said to compare common air with either mercury or water, although they certainly showed the relative specific gravities of the two bodies, taking air for the middle term or common measure of their weights. The common accounts in chemical and in biogra- phical works are materially incorrect respecting the manner in which Mr. Cavendish was led to make his great experiment upon the composition of water in 1781 and the following years. It is said, that while making his experiments on air in 1765 and 1766, he had observed for the first time, that moisture is pro- duced by the combustion of inflammable air, and that this led him, sixteen or seventeen years later, " to com- plete the synthetical formula of water, and to find that the moisture that he had before observed was simple water."* Nothing can be more erroneous than * Penny Cyclopaedia, vol. vi. p. 392. This and other similar 432 CAVENDISH. this whole statement. In Mr. Cavendish's paper, of 1766, upon fixed and inflammable airs, there is not one word said of the moisture formed by the com- bustion ; and respecting inflammable air, the experi- ments are confined entirely to its burning or exploding, to its specific gravity, and to its production. The paper of 1784 is, in fact, entitled ' Experiments upon Air,' and it commences with stating, not that those experiments were undertaken with any view to the water formed by burning inflammable air, but that they were made " with a view to find out the cause of the diminution which common air is well known to suffer by all the various ways in which it is phlogisticated, and to discover what becomes of the air thus lost or con- sumed ;" and the author adds, that besides " determining this fact, they also threw light on the constitution and means of production of dephlogisticated air." In- stead of referring to any former observation of his own either in 1766, or subsequently, on the moisture left by burning inflammable air, he expressly refers to Mr. Warltire's observation of this moisture, as related by Dr. Priestley : and both Mr. Warltire's observation and Dr. Priestley's publication were made in 1781. Upon this observation Mr. Cavendish proceeded to further experiments, with the view of ascertaining " what becomes of the air lost by phlogistication." accounts are plainly given by some persons who never read Mr. Cavendish's writings. But a still greater error occurs in them : they represent him as having first shown that fixed and inflammable airs are separate bodies from common air ; whereas Dr. Black, in his Lectures from 1755 downwards, showed this distinctly by his experi- ments, proving clearly that these gases have nothing in common with the atmospheric air (vol. ii., p. 87, 88). CAVENDISH. 433 For this purpose, he introduced a portion of hydrogen gas into a globe or balloon of glass, sufficiently strong to resist the expansive force of the combustion which had often been observed in mines, and also in experi- ments upon a smaller scale, to produce an explosion. He adapted to the globe two wires of metal, fixing them in air-tight sockets, and bringing their points within a short distance of each other in the inside of the globe ; so that, by an electrical machine, he could send the spark or the shock from the one point to the other, through the gases mixed together in the globe. He found that the whole of the hydrogen gas disappeared by the combustion thus occasioned, and a considerable portion also of the common air. Water was, as usual, found in small quantity, and an acid was also formed. He then weighed accurately the air of both kinds which he exposed to the stream of elec- tricity, and he afterwards weighed the liquid formed by the combustion ; he found that the two weights cor- responded with great accuracy. It was difficult to resist the inference that the union of the two airs had taken place ; and it might further have been inferred that the latent heat which held them in an elastic state had been given out, forming the flame which was produced ; and that water was formed by the union of the two airs, having, of course, less latent heat than was required to keep them in a gaseous state ; but Mr. Cavendish did not approve of this manner of stating the conclusion which Mr. Watt had adopted, because of doubts which he had respect- ing the nature of heat.* The residue of the com- * Page 140. 2 F 434 CAVENDISH. bustion, however, was two-fold: there was an aeriform body left in the glass vessel, as well as liquid in the bottom. This was much smaller in volume than the air which had filled the globe before the combustion, because the hydrogen gas and part of the common air had disappeared. This aeriform residue was also of a different nature from common air ; it was found to be the phlogistic air of Priestley ; the azotic air of Rutherford : and the air consumed in burning the hydrogen gas must, therefore, be the vital air or oxygen gas of the atmosphere. By another ex- periment he more fully ascertained this : for, burning oxygen gas with hydrogen gas, nearly the whole aeriform contents of the globe disappeared, and water, equal in weight to the two gases taken together, remained as the produce of the combustion ; but still an acid was formed, unless in some cases, when very pure oxygen gas was used. Thus was effected the important discovery of the com- position of water, which Watt had inferred some time before from a careful examination of the similar facts collected by former experimentalists ; one of whom, Warltire, had even burned the gases in a close vessel, and by means of electricity. The conclusion arrived at by Mr. Cavendish from his capital experiment was, in his own words, that " dephlogisticated air is in reality nothing but dephlogisticated water, or water deprived of its phlogiston, or in other words, that water consists of dephlogisticated air united to phlogiston, and that inflammable air is either pure phlogiston, or else water united to phlogiston ;" and he then gives his reasons in favour of the second inference, namely, that inflammable air is water united to phlogiston ; but he repeatedly CAVENDISH. 435 dwells on the preference due to this inference over the conclusion that inflammable air is pure phlogiston.* This statement of the theory is somewhat less distinct than Mr. Watt's, who considered water to be dephlo- gisticated air united to inflammable air or pure phlo- giston, and both deprived of their latent heat. But he, as well as Mr. Cavendish, expresses himself with some hesitation, and even, like him, in some passages enter- tains the idea of water as united in a small proportion with inflammable air. The theory, though nearly completed by those great chemists, was perhaps first stated with perfect certainty and distinctness by La- voisier, f In the combustion of hydrogen gas with common air, and even with impure oxygen gas, Cavendish had observed that the water was slightly tinged with acid, though not always when pure oxygen gas was used for the operation. He therefore devised an experiment which should ascertain the nature of this acid, and in what manner it was formed. He passed the electric spark through common air with- out any hydrogen gas being present ; the air was in a receiver over mercury, and the operation was of long continuance, on account of the slowness with which the combination is formed of th^ two gases whereof the atmosphere is composed. He had not supposed that the hydrogen had any share m forming the acid : his theory being that water, and not acid, is the produce of that gas's combustion. He naturally * Philosophical Transactions, 1784, p. 137, 140. t See Appendix to the Life of Watt. 2 F 2 436 CAVENDISH. suspected the acid to be the produce of some union between the azote and the oxygen of the atmosphere, He left the process in the hands of a committee of his scientific friends, fellow-members of the Royal Society ; and after some weeks of constantly passing the electric fluid through a limited portion of air, a small quan- tity of liquid was formed, which readily combined with a solution of potash in water sent up through the mercury. This union was found to be common nitre, having all the qualities of that well-known sub- stance. It detonated with charcoal ; it sparkled when paper impregnated with it was burnt; it gave out nitrous fumes when sulphuric acid was poured on it. There could, therefore, no doubt whatever now exist that nitrous acid is composed of the two airs deprived of latent heat, which form our atmosphere; that it is a true oxide of azote. The undivided merit of this important discovery has never been denied to Mr. Cavendish. Even Lavoisier could not intrude ; but his avidity to claim a share in all discoveries had been exerted respecting the composi- tion of water, which he asserts in his ' Elements of Chemistry' to have been discovered by himself and Mr. Cavendish about the same time. I have shown clearly in the Appendix to the Life of Mr. Watt, that the dis- covery had been previously communicated to the French philosopher ; but it is worth while to consider the ex- periment upon which he grounded his claim ; and that experiment, when examined, is found wholly insufficient to prove the position, even if it had been contrived and performed before the communication of Watt's and Cavendish's discovery. Of that discovery CAVENDISH. 437 it was plainly a corollary — by that discovery it was manifestly suggested. The former experiments, both those of Cavendish and those on which Watt reasoned, were all syn- thetical and decisive — that of Lavoisier was analytical and radically defective. It proved nothing conclusively : it was well enough after the experimentum crucls had demonstrated the proposition ; to that proposition it was a corollary — it was nothing like a critical experiment. He placed water in a retort exposed to heat ; the vapour of the retort, when the water boiled,, was passed through a tube (a gun barrel with the breech-pin knocked out was generally used) ; the tube, if made of earthenware, had iron filings placed in its course ; it was placed in a fire ; its further extremity was connected with a receiver, in which cold water or mercury rose to fill it entirely. As the water slowly boiled there came through the tube, and into the glass receiver, a current of gas, which, upon examination, was found ta be hy- drogen gas, while the iron filings were converted into calx or oxide. The weight of the gas produced, added to the weight acquired by the gun barrel or by the filings during the process, was found to be nearly equal to the weight lost by the water in the retort. Hence the inference was, that the lost portion of water had been decomposed into its two elements, the oxygen gas forming the calx of the iron and the hydrogen gas being received in the glass vessel. But the adversaries of the new doctrine had an answer to this inference far more formidable than any that they could urge against the conclusion drawn from the synthetical experiment. The analytical experiment was liable to all the uncertainty 438 CAVENDISH. of the process called the destructive distillation. The substances found might have been the product, and not merely the educt of the process. It is known that if coal or oleaginous bodies be distilled in close vessels there are obtained gases and water and acids which never existed in the matters subjected to the action of the fire. The component parts of these matters enter into new com- binations with one another under the action of heat, just as a tallow candle or an oil lamp gives lamp-black and water in burning, though no water, but only hydrogen, nor of course any lamp-black, exists in the tallow and the oil. So, in Lavoisier's experiment, the water might contain only oxygen and hydrogen, and the action of the hot iron might have separated them from each other, But it was also quite possible that the iron gave out hydrogen, and that the hot water was partly kept in solution by this gas, partly combined with the iron, for on that supposition the combined weight of the calcined iron and the hydrogen gas would be exactly equal to the united weight of the water evaporated, and of the iron before calcination. The previous discovery of Watt and Cavendish is liable to no such ambiguity ; and it has the merit of also removing all ambiguity from the experiment of Lavoisier, which it manifestly suggested. These great discoveries placed Cavendish in the highest rank of philosophers. No one doubted of nitrous acid ; that he was the undisputed discoverer of the composition of water, before Mr. Watt's claim, is .equally certain ; nor, even now, is it necessary for the defenders of Watt's priority to deny that Cavendish made the great step without any previous knowledge CAVENDISH, 439 of Watt's reasoning, while all admit that his expe-> rimentum crucis was of the greatest value in com- pleting the foundation on which Watt's happy infer- ence had been built. Lavoisier's attempt to intrude himself was wholly unsuccessful ; it had no effect whatever except to tarnish his reputation, already injured sufficiently by his similar attempt to share in the discovery of oxygen. All men held Cavendish's name as enrolled among the greatest discoverers of any age, and only lamented that he did not pursue his brilliant career with more activity, so as to augment still farther the debt of gratitude under which he had laid the scientific world. The reader, especially the French reader, must not suppose that any prejudice respecting Lavoisier has dictated the remarks occasionally made in the course of this work upon his pretensions as a discoverer. It is scarcely possible to estimate too highly the services which he rendered to chemical science by his labours. The truly philosophic spirit which guided his researches had not been found to prevail much before his time in the speculations of chemists. He had a most happy facility in reducing the knowledge of scattered and isolated facts to a system. His talent for generalization has not often been surpassed ; and it led him, together with his admirable freedom from preconceived preju- dice, and his resolute boldness of investigation in unfrequented paths, to make some of the most felicitous inductions, well deserving the title of discoveries, that have ever been made, although the materials of his , inferences were obtained from the experiments and' observations of his predecessors, and his own experi- 440 CAVENDISH. ments, except on the nature of the diamond, led to no material extension of our chemical knowledge. Stript of the plumes in which he sought to array himself, re- pulsed from the avenues by which he would fain have intruded himself among those whose experiments led at once to great discoveries, he is now, on all hands, allowed to have never made us acquainted with a single new gas, or a new substance of any kind, or, except as to carbon, with a single new combination of the old. He did not, like Black, discover carbonic acid or latent heat — he did not, like Priestley, discover oxygen — he did not, like Scheele, discover chlorine — he did not, like Davy, discover the alkaline metals — or like Cavendish, by direct experiment, show how water and nitrous acid are constituted — or, like Ber- thollet, explain of what ammonia consists. But it is equally confessed that, by sound and happy reasoning on the experiments of others, he showed how the process of combustion and of calcination takes place, and to him and his individual researches we owe the important discovery that fixed air, however generated, whether by respiration or by combustion or by fermen- tation (its three great sources, as proved by Black), is the combination of oxygen and carbon. Nor is it any deroga- tion from his claims to the title of a discoverer of physical truths that his generalization pushed too far made him regard oxygen as necessary to all combustion and all acidification, whereas it has been found that heat and light are abundantly evolved both by the combustion of metals and sulphur in close vessels — by the combustion of hydrogen and azotic gas — and by the combination of metals with chlorine ; and also that chlorine, an acid CAVENDISH. 441 of the strongest kind, contains no oxygen at all, while the alkalis themselves are oxides. The doctrine of latent heat was happily applied by him to the union of gases with bodies, and if he had only followed that doctrine more closely he would have avoided the error into which he fell, and perceived that other gases as well as oxygen may support flame, and that all, on becoming liquid or solid, must part with heat. Against his error respecting the constitution of acids may justly be set the great merit of his conjecture, that the fixed alkalis are oxides of metals ; for this has been since proved, and the conjecture is a sufficient evidence that he did not doggedly adhere to his theory of the acidi- fying principle. It does not appear that Mr. Cavendish ever after 1785, when he discovered the nature of nitrous acid, prosecuted his chemical inquiries so as to make new discoveries ; but beside making numberless use- ful chemical experiments, about ten years later he engaged in some important experiments upon the force of attraction. It occurred to him that he could measure that force, and thereby ascertain the density of the earth by accurately observing the action of bodies suddenly exhibited in the neighbourhood of a horizontal lever nicely balanced, loaded with equal leaden balls of a small size at its two ends, and pro- tected from all aerial currents by being inclosed in a box. In that box a telescope and lamp were placed, that the motions of the lever might be carefully ob- served. On approaching the external leaden balls made use of, whose diameter was eight inches, to the small ones inclosed, and near the lever, it was found that a 442 CAVENDISH. horizontal oscillation took place. This was measured ; and the oscillation caused by the earth on a pendulum being known, as well as the relative specific gravities of lead and water, it was found, upon the medium of his observations, that the earth's density is to that of water as eleven to two, or five-and-a-half times greater. Dr. Hutton, who repeated his calculations, made the result five three-tenths, or as fifty-three to ten. Maske- lyne's experiments at Schehallion made the proportion as five to one. Zach's experiment on a smaller hill near Marseilles did not give a result materially different. A paper on the civil year of the Hindus, connected, like Newton's chronological works, with astronomical researches, an account of a new eudiometer, and some papers on electricity, form the rest of this great philo- sopher's works ; and altogether they shrink into a very inconsiderable bulk compared with the voluminous works of inferior men. In this, as in other respects, we trace his resemblance to Black. Indeed the admi- rable contrivance of their experiments — their circum- spect preparation of the ground by previous discussion of principles — the cautious following of facts, and yet the resolute adoption of legitimate consequences in their generalizations — the elegance of their processes, and the conciseness of their descriptions and remarks, with an unsparing rejection of every thing superfluous — >formsthe characteristic of both those illustrious students of nature. While, as regards Cavendish's writings, it has been, and as regards Black's it might have been, justly said by one that every sentence will bear the microscope ; another writer, the most eminentof his successors, has, with equal truth, described his processes as of so finished a nature, CAVENDISH, 443 so perfected by the hand of a master, as to require no correction ; and, though contrived in the infancy of the science, yet to remain unsurpassed, perhaps unequalled, for accuracy and beauty at the present day. The world, even the scientific world, dazzled by the brilliancy of those discoveries which we have described, is wont to regard Cavendish as a chemist merely. But it was not only in chemical science and in a few depart- ments of natural philosophy that this great man had thoroughly exercised himself ; he was profoundly versed in every branch of physics, and was a most complete and accomplished mathematician. I have had access to the manuscripts which he left behind him ; and it would be difficult to name any subject which had not engaged his close attention : all had been made the subject not only of his study, but of his original investigations. The two papers on Electricity which he published in the ' Philosophical Transactions ' contain, the one of 1776, the first distinct statement of the difference be- tween animal and common electricity ; the other, in 1771, twenty-seven propositions upon the action of the electric fluid, treated mathematically. They are grounded upon the general hypothesis that the par- ticles of the fluid repel one another, and attract those of other matter with a force inversely as some lesser power than the cube of the distance ; and with this theory the experiments which he examines are found to tally perfectly. But his voluminous unpublished papers show how constantly his life was devoted to experimental inquiries, and analytical or geometrical investigations. Beside ranging over the whole of che- mical science, they relate to various branches of optics, 444 CAVENDISH. of physical and of practical astronomy — of the theory of mathematical and astronomical instruments — of me- chanical and dynamical sciences, both theoretical and practical — of pure mathematics in all its branches, geo- metry, the integral and differential calculus, the doctrine of chances and annuities. He seems in his application of mathematics to physics to have disregarded elegance, and even simplicity, and to have chosen always the shortest and most certain path to his object. Accordingly this somewhat surprises the mathematical reader ; as when we find him using ^7 (or rather ~r> for he always employs the Newtonian notation) for the sub- normal, having taken x for some other quantity than the abscissa, and using three letters, as a, 2, and a% to denote segments of the same line, when perhaps a is the whole line, and a — x is equal to z. But that he had the most familiar and masterly knowledge of the calculus is plain throughout all his investigations, as it is that his trust in its powers induced him to throw himself willingly and habitually upon them. In this respect he stands not only at the head of chemical philosophers, but alone among them, with perhaps one or two exceptions in the French school. In giving the history of his labours, and the cha- racter of his intellectual capacity, we have written the life of Cavendish. His personal history cannot be expected to have any striking interest ; yet they who have been dwelling on his scientific eminence will not be displeased to know somewhat of his ordinary life. He was of a most reserved disposition, and peculiarly shy habits. This led to some singularity of manner, CAVENDISH. 445 which was further increased by a hesitation or difficulty of speech, and a thin shrill voice. He entered diffi- dently into any conversation, and seemed to dislike being spoken to. He would often leave the place where he was addressed, and leave it abruptly, with a kind of cry or ejaculation, as if scared and disturbed. He lived in a house on Clapham Common, and his library, vast in extent, was at another place, because he made it accessible to all, and did not wish to be trou- bled by those who resorted to it. He allowed friends to take books from it, and he himself never took one without giving a receipt for it. On the death of his librarian he began the practice of himself attending one day in the week to give out and take in books. His large income was allowed to accumulate ; and when his bank- ers, after finding that a very considerable balance was always left in their hands, mentioned the circumstance, suggesting that it might be invested to some profit, he answered with much simplicity, that if the balance was an inconvenience to them he could go to another banker. Himself a man of no expense, his habits never varied, nor did his style of living at all suffer a change on suc- ceeding to his uncle's large fortune. His purse was ever accessible to the claims of charity, as well as to pro- posals for the promotion of scientific pursuits. Having formed a high opinion of Dr. (afterwards Sir Charles) Blagden's capacity for science, he settled a consider- able annuity on him, upon condition that he should give up his profession and devote himself to philosophy ; with the former portion of which condition the Doctor complied, devoting himself to the hopeless pursuit of a larger income in the person of Lavoisier's widow, who 446 CAVENDISH. preferred marrying Count Rumford.* Mr. Cavendish received no one at his residence ; he ordered his dinner daily by a note which he left at a certain hour on the hall table, where the housekeeper was to take it, for he held no communication with his female domestics, from his morbid shyness. It followed, as a matter of course, that his servants thought him strange, and his neigh- bours deemed him out of his mind. He hardly ever went into society. The only exceptions I am aware of are an occasional christening at Devonshire or Burling- ton House, the meetings of the Royal Society, and Sir Joseph Banks' weekly conversaziones. At both the latter places I have met him, and recollect the shrill cry he uttered as he shuffled quickly from room to room, seeming to be annoyed if looked at, but sometimes approaching to hear what was passing among others. His face was intelligent and mild, though, from the nervous irritation which he seemed to feel, the expres- sion could hardly be called calm. It is not likely that he ever should have been induced to sit for his picture ; the result therefore of any such experiment is want- ing. His dress was of the oldest fashion, a greyish green coat and waistcoat, with flaps, a small cocked hat, and his hair dressed like a wig (which possibly it was) with a thick clubbed tail. His walk was quick and uneasy ; of course he never appeared in London unless lying back in the corner of his carriage. He probably uttered fewer words in the course of his life than any man who ever lived to fourscore years, not at all excepting the monks of La Trappe. * He left Sir Charles a legacy of 15,000/. ; which was generally understood to have fallen much short of his ample expectations. CAVENDISH. 447 Mr. Cavendish died on the 10th of March, 1810, after a short illness, probably the first as well as the last under which he ever suffered. His habit of curious observation continued to the end. He was desirous of marking the progress of disease, and the gradual ex- tinction of the vital powers. With this view, that he might not be disturbed he desired to be left alone. His servant returning sooner than he had wished was ordered again to leave the chamber of death, and when he came back a second time he found his master had expired. ( 448 DAVY. SIR HUMPHRY DAVY being now removed beyond the reach of such feelings, as he ought always to have been above their influence, that may be said without offence of which he so disliked the mention : he had the honour of raising himself to the highest place among the chemical philosophers of the age ; emerging by his merit alone from an obscure condition. His father was a carver in wood at Penzance, in Corn- wall ; a man of some ingenuity in his craft. He pos- sessed a small landed property in the village of Varfell, near Penzance, and Davy was born there in 1778. He received the rudiments of his education at a school in Truro, but was very early apprenticed to an apo- thecary at Penzance, where, disliking the profession to which he had been destined, he occupied himself with chemical experiments, ingeniously contriving to make the utensils of the shop and the kitchen serve for ap- paratus ; and it is remembered of him that he fre- quently alarmed the household by his explosions. The result of his dislike to the shop was a disagree- ment with his master, and he went to another in the same place ; but here he continued in the same course. Pursuing a plan of study which he had laid down for JEitararai •// //* TIAVT. nied ty Voita, the a«thor of the pik, and indeed of the science which, like the continent of America, has borne of a liqmoi copahk of decomposing one or other of the both supposed to be equally necessary to the of the electric stream. which were numerous and admirably devised laboriously conducted, now showed that the of two metals was not required to pr the electricity. One metal,, and one other substance •paiated firom M^ with a fluid acting upon either the metal or the substance; or a metal separating two fluids, 1 C7 oar of which acts upon k ; nay, one metal exposed to the sMne ftud, but acted upon differently on its diffe- ioot sides or Jiifatm by the fluid's strength differing on the diflmnt sides ; or one and the same metal in difi»g»t pieces plunged into the same fluid, at an interval of time — were all found to be combina- tion which gave the galvanic (or voltaic) shock, the •one in kind, though varying in _ih. In all these cases, and m every production of electricity W the roltaic process, the chemical action of a fluid oonco- Durin«: tike fiwe following years Davy continued his i; and in the autumn of 1806 he coinniu- to the Boyal Society his discovery of the con- ends of the electric circle VY. and the different component parts of bodies submitted to the action of the fluid. Nothing could be more singular and unexpected than the laws which he now found to regulate this operation, nor anything which promised more clearly a rich harvest of new discoveries The effect of the current, whether of common or gal- vanic electricity, in decomposing substances through which it passed, had been before known. Thus water had been resolved into its two elements by the passing of the fluid through wires whose points were opposite to each other at a small distance. Nicholson had first made this happy application of the voltaic pile; but he and others had been much disturbed by finding other substances produced as well as oxygen and hy- drogen gases. This perplexing circumstance was care- fully investigated by Davy ; and he showed by a mas- terly course of experiments, that these substances owed their origin entirely to impurities in the water. When it was quite pure, they wholly disappeared. But he now proceeded farther, and found that when the electric current is thus passed, there is always a separation operated differently at the negative and at the positive part of the current. The oxygen of the water, for example, was accumulated round the positive wire ; its hydrogen round the negative. So when a neutral salt was subjected to the process, its acid was evolved round the positive ; its alkaline base round the negative wire. The same thing happened when a me- tallic oxide was operated upon ; its oxygen went to the positive, its metallic base to the negative side. The oxygen, or the acid with the oxygen, went to the for- mer ; the particles of the base were transferred to the 456 DAVY. latter, along with the hydrogen of the water in which the solution was made. But a still more extraordinary phenomenon was observed. If there was a liquid in- terposed between the two poles and the body to be de- composed, the acid, or the oxygen, was found to pass through that interposed liquid to the positive pole, the hydrogen and the matter of the base to the negative pole, and without acting upon the substance of the in- terposed liquid. Thus suppose a vegetable colour tinging the water in an intermediate cup, acid will pass through it without reddening it, and alkali with- out making it green. Nay, an acid will pass through an alkaline solution, or an alkali through an acid, without uniting in either case to form a neutral salt, unless the neutral compound is insoluble, for in that case it falls to the bottom. But muriatic acid will pass through a solution of potash, having been carried over from a solution of common sea salt by the electrical current, or soda will pass through muriatic acid in the same circumstances, without forming in the former case nitrate of potash, or in the latter nitrate of soda. It was also found that the exception in the case of in- soluble compounds arises from the mechanical effect of their insolubility, their falling to the bottom ; for if supported, as it were, on threads of any convenient substance passing through the intermediate liquid in the line of the electric current, the acid or alkali will pass through that liquid. Thus films of asbestos conduct- ing the electric stream, enabled magnesia or lime to pass ; and so were the particles of metal carried over when separated by the operation from nitrate of silver. DAVY. 457 It thus appeared certain that an indissoluble con- nexion exists between chemical and electric action, if indeed it was not even proved that chemical affinity and electricity are identical. The science of Electro- chemistry, at all events, now arose out of Davy's dis- coveries, and he is entitled to be regarded as its founder. It may easily be conceived that these important truths excited generally the anxious attention of philo- sophers. The French National Institute, greatly to their honour, though the war between the two coun- tries never raged more fiercely than now, and France never reached a higher pitch of military glory, crowned Davy with the first honour founded by Napoleon for scientific desert. But it was even more honourable to the philosopher, that great as his discoveries had been, expectation was high of the still more important results which must soon come from the discovery of so new a law of electrical and chemical action. I can well re- member that we used in discussing the subject to look forward with perfect confidence to the analysis of the bodies which had hitherto proved the most stubborn, and expected soon to find the fixed alkalis, and even the alkaline earths, shown to be oxides, as by some very imperfect experiments they had at one time been supposed to be proved, when it was ascertained that the metallic buttons found at the bottom of the crucible in which their reduction had been attempted by carbon- aceous or phosphoric re-agents, had come from the black lead in the pot. Nor must we omit to mention the truly candid and magnanimous proceeding of Davy, so worthy of a philosopher, in making public, with the fullest details, his proceedings, by which it was mani- 458 DAVY. fest he intended still to persevere till he should make other discoveries. Any one possessed of a strong bat- tery, deeply reflecting on the paper of autumn 1806, and perceiving that the positive wire had such a strong attraction for oxygen as to take it from metallic oxides, reducing them to their reguline state, might well have bethought him of subjecting the alkalis to his machine ; and he would then have had the fame, though, in truth, Davy would have had the merit, of the grand discovery. That discovery was not long delayed. About a year after the former, that is in October 1807, after in vain endeavouring to decompose the alkalis when mixed with water, for he then only could decompose that fluid, he exposed them in the dry state ; that is, made liquid by fusion, without any other substance but heat to dissolve them — and, to his great delight, he found, as he had a right to expect, that the process of deoxi- dation proceeded by the positive wire attracting the oxygen, while globules of a metallic substance were found at the negative wire. The great attraction of this metal for oxygen made it impossible to keep it either in the air or in water. It burnt spontaneously in the air and became alkali — it decomposed water in like manner, and formed an alkaline solution. The two fixed alkalis both yielded in this process metallic bases ; but that of potash had alone the quality of combustion at the temperature of 150°, and it was, though a metal, lighter than water in the proportion of 97 to 100. When thrown into water in the air, it detonates and burns with violence, forming a solution of potash. The metal from soda is still lighter, being to water as 86 to 100 ; but it does not so easily unite with oxygen, DAVY. 459 though it decomposes water with a hissing noise, and makes with it a solution of soda. To these metals the discoverer gave the name of potassium and sodium. The glory of having now made the greatest discovery of the age was plainly Davy's ; and it was not the result of happy accident, but of laborious investigation, conducted with a skill and a patience equally admirable, and according to the strict rules of the soundest philo- sophy. He had indeed begun by discovering the laws of electrical action, and had thus formed the means of his new discovery, which was the fruit of the science he had founded, as Newton's theory of dynamics and of astronomy was the fruit of the calculus which he had so marvellously discovered when hardly arrived at man's estate. The wonder excited by the strange bodies with which philosophers were thus brought acquainted, was of course in part owing to their novel and singular properties, which formed no part of the discoverer's merits, yet might be reckoned as the perquisites of his genius. His praise would have been the same if in- stead of at once discovering the alkalis to be oxides, and the metal forming the base to be one lighter than water, or bees'-wax or box-wood, and the other to burn unheated in the open air, he had only shown those salts to be oxides of well-known metals. Yet, as his investigation had been crowned with the discovery of strange substances, metallic, and yet like no other metals, we justly admire the more, and the more thank him for his double service rendered to science. The long labour thus ending in so mighty a result, and the excitement naturally enough produced in an irritable habit, threw him into an illness of a most 460 DAVY. serious complexion. For many days he lay between life and death in a low nervous fever, and it was not till the following March that he could resume his inquiries into the composition of the alkaline earths: It is to the credit of chemists that no one deemed himself at liberty to interfere with him, as any one might now by only following his footsteps have done, and thus analysed these earthy bodies. He himself, early in the summer following his illness, had reduced lime, magnesia, strontites, and barytes. In these experiments he was greatly assisted by the ingenious contrivances which Gay-Lussac and Thenard had recently used for the reduction of the alkaline oxides. The metals thus discovered were not any wise light or fusible like potassium and sodium ; but they burnt with a bright light on being exposed to considerable degrees of heat, and they decomposed water ; and either by their com- bustion, or their exhibition to water, they reproduced the alkaline earths. A number of other experimental researches led Davy to new and curious observations on the constitu- tion and habits of different substances. But we need only mention the most important of these, for it was a discovery very unexpected both by himself and the chemical world at large. The acid hitherto called oxy- genated muriatic, or oxymuriatic, on account of its powerful acid qualities, had been always from thence supposed to contain an excess of oxygen, believed to be the acidifying principle. At last Gay-Lussac and Thenard, in 1809, concluded from some experimental researches, or rather they suspected, that it might be a simple and elementary substance ; but they on the whole still inclined to think it contained oxygen according to DAVY. 461 the old and received opinion. Davy now found, by a course of satisfactory experiments which have fixed the opinions of all philosophers on the subject, that the suspicion of those eminent men was well founded ; that the oxymuriatic acid is a simple substance, containing no oxygen ; that it unites with oxygen to form an acid, which forms with alkalis the detonating salts hitherto called oxymuriates, as being supposed to contain oxymuriatic acid combined with alkaline bases ; and finally, that with hydrogen it forms the acid long and well known as the muriatic or marine. To the oxymuriatic acid he gave the name of chlorine from its green colour, and to common muriatic acid that of hydrochlorine. The union of chlorine and oxygen he calls chlorine acid, and its compounds, of course, chlorates. This is justly reckoned one of the most im- portant of Davy's many brilliant discoveries. It remains to make mention of the valuable present which this great philosopher offered to humanity — his safety-lamp. The dreadful ravages made on human life by the fire-damp explosions — that is, the burning of hydrogen gas in mines — had often attracted the notice of both the mine-owner and the philanthropist. Various inventions had been fallen upon to give light in those recesses of the earth with so low a degree of heat as should be insufficient to explode the gas. One of them was a series of flints playing by machinery against each other so as to give a dim light ; but this had very little success ; it was clumsy, and it was not ef- fectual so as to cause its use by miners. The ventilation of the galleries by furnaces and even by air-pumps was chiefly relied on as a preventive ; but gas would collect 462 DAVY. in spite of all preventives, and the destruction of a hundred or more lives was not an unusual calamity. Davy about the year 1815 turned his attention to the subject, and after fully ascertaining that carburetted hydrogen is the cause of the fire-damp, and finding in what proportions it must be mixed with air in order to explode (between six and fourteen times its bulk), he was surprised to observe, in the course of his experi- ments made for the purpose of ascertaining how the inflammation takes place, that the flames will not pass through tubes of a certain length or smallness of bore. He then found that if the length be diminished, and the bore also reduced, the flames will not pass ; and he fur- ther found that by multiplying the number of the tubes, their length may safely be diminished to hardly any- thing, provided their bore be proportionally lessened. Hence it appeared that gauze of wire, whose meshes were only one twenty-second of an inch diameter, stopped the flame, and prevented the explosion. The candle or lamp being wrapt in such gauze, and all access to the external air prevented except through the meshes, it is found that the lamp may be safely introduced into a gallery filled with fire-damp ; a feeble blue flame will take place inside the gauze, but no explosion, even if the wire be heated nearly red. The theory is, but it seems very questionable, that the conducting power of the wire carrying off the heat pre- vents a sufficient quantity reaching the explosive com- pound. Subsequent inquiries seem to prove that although in a still atmosphere of explosive gas the lamp is a perfect protection, yet it does not prevent a cur- rent of gas from penetrating to the flame and exploding. DAVY. 463 It is attempted to guard against this by interposing a tin shield or screen ; but a current very often in mining operations arises before any notice can be given. Had Davy's life and health been prolonged, he might have further improved his invention so as to meet this ob- jection. He certainly never was fully convinced of its force, as I know from having discussed the subject with him ; and no doubt the testimony of so great an engineer as the late Mr. Buddie, given before a Par- liamentary Committee to whom the examination of this important subject was referred, deserves great attention. He positively affirmed that " having seen 1000, and sometimes 1500 safety-lamps in daily use, and in all possible varieties of explosive mixtures, he had never known one solitary instance of an explosion." As for the lamentable accidents which continue to happen, we can scarcely doubt that they originate in the dreadful carelessness of their own and of other men's lives, which seems to be engendered in those who are habitually exposed to great danger. That they themselves are the first to suffer for it, can only suppress the outward expression of the feelings which recklessness like this is fitted to produce. It redounds to the credit of the north country mine- owners that in 1817 they invited the inventor of the Lamp to a public entertainment, and presented him with a service of plate of two thousand pounds value. It must be remembered that he had generously given to the public the whole benefit of his invention, and thus sacrificed the ample profit which a patent must have enabled him to acquire for himself. Davy had as early as 1806 been chosen a foreign associate of the French Institute. In 1812 he received 464 DAVY. from the Regent the honour of knighthood. About the same time he married Mrs. Apreece, a lady whose ample fortune was by far the least valuable part of her accomplishments — a person of great virtue, admirable talents, and extensive information. Of this marriage there has been no issue. In October, 1813, he published his ' Elements of Chemical Philosophy,' — a hasty and even somewhat crude work, but abounding, as what- ever he wrote was sure to abound, in important and ingenious observations. The following year appeared his 'Elements of Agricultural Chemistry,' of which the same general character may be given. In 1816 he was created a baronet. Napoleon had, during the war, given him permis- sion to visit the extinguished volcanoes in Dauvergne, and to pass through France towards Naples, Vesuvius being then in a state of eruption. His reception at Paris was very warm, hut unfortunately he failed to retain the affection of his colleagues in the Institute. Their complaint against him for having interfered, as they termed it, with their recent discovery of iodine, on which, having obtained a specimen, he chose, naturally enough, to make experiments, appears incom- parably absurd. He had never complained of their in- terference, during his illness in 1807, with the process of deoxygenation by means of galvanic action ; on the contrary, he had availed himself thankfully of the lights shed by their ingenuity on his process, and had immediately after made new discoveries, at which they had failed to arrive. It may be more true that his manners were unpleasing ; and, as ever happens when a great man is also a shy one, he was charged with being supercilious and cold. They who knew him DAVY. 465 will at once acquit him of any such charge ; but he was painfully timid by nature when mixing with so- ciety ; and hence the mistake of our neighbours, who, though great critics in manner, are far from being infallible, and are exceedingly susceptible — fully as sus- ceptible as he was shy. Possibly they looked down upon him in consequence of a peculiarity which he no doubt had. He was fond of poetry, and an ardent ad- mirer of beauty in natural scenery. But of beauty in the arts he was nearly insensible. They used to say in Paris that on seeing the Louvre, he exclaimed that one of its statues was " a beautiful stalactite ;" and it is possible that this callousness, or this jest, which- ever it might be, excited the scorn or the humour of men not more sincere lovers of sculpture than himself, or more able judges of its merits, but better disposed to conceal their want of taste or want of skill. When Sir Joseph Banks terminated his long and respectable course in 1820, Davy was unanimously chosen to succeed him as President of the Royal So- ciety, and continued to fill that distinguished office un- til, his health having failed, he resigned it in 1827, and was succeeded by his early patron Davies Giddy. To- wards the end of 1825 he had an apoplectic seizure, which, though slight (if any such attack can be so called), left a paralytic weakness behind, and he was ordered to go abroad in search of a milder and dryer climate. He returned home in the following autumn, not very ill, but not much restored in strength, and unable to continue his scientific labours. The work on fly-fishing called ' Salmoriia ' was the amusement of those hours in which, comparatively feeble, his mind 2 H 466 DAVY. yet exerted what energy remained to it, on the favourite pursuit of his leisure. It contains both curious in- formation on natural history, and many passages of lively and even poetical description. The same may be said of many things in his latest work, ' Last Days of a Philosopher,' which he wrote in the year after, when he again went to the continent in search of health. He wintered at Rome, and in May 1829, on his arrival at Geneva, after passing the day in excel- lent spirits, and dining heartily on fish, he had a fatal apoplectic attack in the night, and died early in the next morning, 29th May, without a struggle. There needs no further remark, no general charac- ter, to present a portrait of this eminent individual. Whoever has perused the history of his great exploits in science, with a due knowledge of the subject, has already discerned his place, highest among all the great discoverers of his time. Even he who has little acquaintance with the subjects of his labours may easily perceive how brilliant a reputation he must have en- joyed, and how justly ; while he who can draw no such inference from the facts would fail to obtain any knowledge of Davy's excellence from all the panegyrics with which general description could encircle his name.* * It may not be impertinent to relate here a singular proof of the admiration in which his name was held by his countrymen, and how well it became known even among the common people. Re- tiring home one evening he observed an ordinary man showing the moon and a planet through a telescope placed upon the pavement. He went up and paid his pence for a look. But no such thing would they permit. " That's Sir Humphry," ran among the people ; and the exhibitor, returning his money, said, with an important air which exceedingly delighted him, that he could not think of taking any- thing from a brother philosopher. (467) S I M S 0 N. THE wonderful progress that has been made in the pure mathematics since the application of algebra to geometry, begun by Vieta in the sixteenth, completed by Des Cartes in the seventeenth century, and espe- cially the still more marvellous extension of analytical science by Newton and his followers, since the inven- tion of the Calculus, has, for the last hundred years and more, cast into the shade the methods of investiga- tion which preceded those now in such general use, and so well adapted to afford facilities unknown while mathematicians only possessed a less perfect instrument of investigation. It is nevertheless to be observed that the older method possessed qualities of extra- ordinary value. It enabled us to investigate some kinds of propositions to which algebraic reasoning is little applicable ; it always had an elegance peculiarly its own ; it exhibited at each step the course which the reasoning followed, instead of concealing that course till the result came out ; it exercised the facul- ties more severely, because it was less mechanical than the operations of the analyst. That it afforded evi- dence of a higher character, more rigorous in its na- ture than that on which algebraic reasoning rests, •2 H2 468 SIMSON. cannot with any correctness be affirmed ; both are equally strict ; indeed if each be mathematical in its nature, and consist of a series of identical propositions arising one out of another, neither can be less perfect than the other, for of certainty there can be no de- grees. Nevertheless it must be a matter of regret— and here the great master and author of modern mathe- matics has joined in expressing it — that so much less attention is now paid to the Ancient Geometry than its beauty and clearness deserve ; and if he could justly make this complaint a century and a half ago, when the old method had but recently, and only in part, fallen into neglect and disuse, how much more are such regrets natural in our day, when the very name of the Ancient Analysis has almost ceased to be known, and the beauties of the Greek Geometry are entirely veiled from the mathematician's eyes ! It be- comes, for this reason, necessary that the life of Sim- son, the great restorer of that geometry, should be prefaced by some remarks upon the nature of the sci- ence, in order that, in giving an account of his works, we may say his discoveries, it may not appear that we are recording the services of a great man to some sci- ence different from the mathematical. The analysis of the Greek geometers was a method of investigation of peculiar elegance, and of no incon- siderable power. It consisted in supposing the thing as already done, the problem solved, or the truth of the theorem established ; and from thence it reasoned until something was found, some point reached, by pursuing steps each one of which led to the next, and by only assuming things which were already known S1MSON. 469 being ascertained by former discoveries. The thing thus found, the point reached, was the discovery of something which could by known methods be per- formed, or of something which, if not self-evident, was already by former discovery proved to be true ; and in the one case a construction was thus found by which the problem was solved, in the other a proof was ob- tained that the theorem was true, because in both cases the ultimate point had been reached by strictly legiti- mate reasoning, from the assumption that the problem had been solved, or the assumption that the theorem was true. Thus, if it were required from a given point in a straight line given by position, to draw a straight line which should be cut by a given circle in segments, whose rectangle was equal to that of the segments of the diameter perpendicular to the given line — the thing is supposed to be done ; and the equality of the rect- angles gives a proportion between the segments of the two lines, such that, joining the point supposed to be found, but not found, with the extremity of the dia- meter, the angle of that line with the line sought but not found, is shown by similar triangles to be a right angle, i. e., the angle in a semicircle. Therefore the point through which the line must be drawn is the point at which the perpendicular cuts the given circle. Then, suppose the point given through which the line is to be drawn, if we find that the curve in which the other points are situate is a circle, we have a local theorem, affirming that, if lines be drawn through any point to a line perpendicular to the diameter, the rect- angle made by the segments of all the lines cutting the perpendicular is constant ; and this theorem would be 470 SIMSON. demonstrated by supposing the thing true, and thus reasoning till we find that the angle in a semicircle is a right angle, a known truth. Lastly, suppose we change the hypothesis, and leave out the position of the point as given, and inquire after the point in the given straight line from which a line being drawn through a point to be found in the circle, the seg- ments will contain a rectangle equal to the rect- angle under the perpendicular segments — we find that one point answers this condition, but also that the problem becomes indeterminate ; for every line drawn through that point to every point in the given straight line has segments, whose rectangle is equal to that under the segments of the perpendicular. The enun- ciation of this truth, of this possibility of finding such a point in the circle, is a Porism. The Greek geo- meters of the more modern school, or lower age, defined a Porism to be a proposition differing from a local theorem by a defect or defalcation in the hypothesis ; and accordingly we find that this porism is derived from the local theorem formerly given, by leaving out part of the hypothesis. But we shall afterwards have occa- sion to observe that this is an illogical and imperfect definition, not coextensive with the thing defined ; the above proposition, however, answers every definition of a Porism. The demonstration of the theorem or of the construc- tion obtained by investigation in this manner of pro- ceeding, is called synthesis, or composition, in opposi- tion to the analysis, or the process of investigation ; and it is frequently said that Plato imported the whole system in the visits which he made, like Thales of Miletus and Pythagoras, to study under the Egyptian SIMSON. 471 geometers, and afterwards to converse with Theodoras at Gyrene, and the Pythagorean School in Italy. But it can hardly be supposed that all the preceding geo- meters had worked their problems and theorems at random ; that Thales and Pythagoras with their dis- ciples, a century and a half before Plato, and Hip- pocrates, half a century before his time, had no knowledge of the analytical method, and pursued no systematic plan in their researches, devoted as their age was to geometrical studies. Plato may have im- proved and further systematized the method, as he was no doubt deeply impressed with the paramount im- portance of geometry, and even inscribed upon the gates of the Lyceum a prohibition against any one entering who was ignorant of it. The same spirit of exaggera- tion which ascribes to him the analytical method, has also given rise to the notion that he was the discoverer of the Conic Sections ; a notion- which is without any truth and without the least probability. Of the works written by the Greek geometers some have come down to us ; some of the most valuable, as the ' Elements' and ' Data' of Euclid, and the ' Conies' of Apollonius. Others are lost ; but, happily, Pappus, a mathematician of some merit, who flourished in the Alexandrian school about the end of the fourth cen- tury, has left a valuable account of the geometrical writings of the elder Greeks. His work is of a mis- cellaneous nature, as its name, 'Mathematical Col- lections,' implies ; and excepting a few passages, it has never been published in the original Greek. Com- mandini, of Urbino, made a translation of the whole six books then discovered; the first has never been 472 SIMSON. found, but half the second being in the Savilian library at Oxford, was translated by Wallis a century later. Commandini's translation, with his learned commen- tary, was not printed before his death, but the Duke of Urbino (Francesco Maria) caused it to be published in 1588, at Pisa, and a second edition was published at Venice the next year : a fact most honourable to that learned and accomplished age, when we recollect how many years Newton's immortal work was pub- lished before it reached a second edition, and that in the seventeenth and eighteenth centuries; The two first books of Pappus appear to have been purely arithmetical, so that their loss is little to be lamented. The eighth is on mechanics, and the other five are geometrical. The most interesting portion is the seventh ; the introduction of which, addressed to his son as a guide of his geometrical studies, contains a full enumeration of the works written by the Greek geometers, and an account of the particular subjects which each treated, in some instances giving a summary of the propositions themselves with more or less ob- scurity, but always with great brevity. Among them was a work which excited great interest, and for a long time baffled the conjectures of mathematicians, Euclid's three books of ' Porisms :' of these we shall afterwards have occasion to speak more fully. His 'Loci ad Superficiem,' apparently treating of curves of double curvature, is another, the loss of which was greatly lamented, the more because Pappus has given no account of its contents. This he had done in the case of the ' Loci Plani' of Apollonius. Euclid's four books on conic sections are also lost: but of Apol- SIMSON. 473 lonius's eight books on the same subject, the most important of the whole series, the ' Elements' excepted, four were preserved, and three more were discovered in the seventeenth century. His Inclinations, his Tactions or Tangencies, his sections of Space and of Ratio, and his Determinate section, however curious, are of less importance ; all of them are lost. For many years Commandini's publication of the * Collections' and his commentary did not lead to any attempt at restoring the lost works from the general account given by Pappus. Albert Girard, in 1634, informs us in a note to an edition of Stevinus, that he had restored Euclid's * Porisms/ a thing eminently unlikely, as he never published any part of his resto- ration, and it was not found after his decease. In 1637, Fermat restored the ' Loci Plani' of Apollonius, but in a manner so little according to the ancient analysis, that we cannot be said to approach by means of his labours the lost book on this subject. In 1615, De la Hire, a lover and a successful cultivator of the ancient method, published his Conic Sections, but synthetically treated ; he added afterwards other works on epicycloids and conchoids, treated on the analytical plan. L'Hopital, at the end of the seventeenth century, published an excellent treatise on Conies, but purely algebraical. At the beginning of the eighteenth cen- tury, Viviani and Grandi applied themselves to the ancient geometry ; and the former gave a conjectural restoration (Divinatio) of Aristseus's * Loci Solidi,' the curves of the second or Conic order. But all these attempts were exceedingly unsuccessful, and the world was left in the dark, for the most part, on the 474 SIMSON. highly interesting subject of the Greek geometry. We shall presently see that both Fermat and Halley, its most successful students, had made but an incon- siderable progress in the most difficult branches. How entirely the academicians of France were either careless of those matters, or ignorant, or both, appears by the ' Encyclopedic ; ' the mathematical department of which was under no less a geometrician than d'Alembert. The definition there given of ana- lysis makes it synonymous with algebra : and yet mention is made of the ancient writers on analysis, and of the introduction to the seventh book of Pappus, with only this remark, that those authors differ much from the modern analysts. But the article ' Arithmetic' (vol. i., p. 677) demonstrates this ignorance completely ; and that Pappus's celebrated introduction had been referred to by one who never read it. We there find it said, that Plato is sup- posed to have invented the ancient analysis ; that Euclid, Apollonius, and others, including Pappus himself, studied it, but that we are quite ignorant of what it was : only that it is by some conceived to have resembled our algebra, as else Archimedes could never have made his great geometrical discoveries. It is, certainly, quite incredible that such a name as d'Alembert's should be found affixed to this statement, which the mere reading of any one page of Pappus's books must have shown to be wholly erroneous ; and our wonder is the greater, inasmuch as Simson's ad- mirable restoration of Apollonius's ' Loci Plani' had been published five years before the * Encyclopedic ' appeared. SIMSON. 475 Again, in the ' Encyclopedic,' the word Analysis, as meaning the Greek method, and not algebra, is not even to be found. Nor do the words synthesis, or composition, inclinations, tactions or tangencies occur at all ; and though Porisms are mentioned, it is only to show the same ignorance of the subject : for that word is said to be synonymous with ' lemma/ because it is sometimes used by Pappus in the sense of subsidiary proposition. When Clairault wrote his inestimable work on curves of double curvature, he made no reference whatever to Euclid's ' Loci ad Superficiem,' much less did he handle the subject after the same manner ; he deals, indeed, with matters beyond the reach of the Greek geometry. Such was the state of this science when Robert Simson first applied to it his genius, equally vigorous and undaunted, with the taste which he had early imbibed for the beauty, the simplicity, and the close- ness of the ancient analysis. ROBERT SIMSON was born on the 14th October (O.S.), 1687, at Kirton Hill, in the parish of Wester Kilbride, in Ayrshire. His father, John Simson, was a mer- chant in Glasgow : his grandfather, Patrick, was mini- ster of Renfrew, and Dean of the Faculties in the Uni- versity of Glasgow. Having been deprived at the Re- storation, on being reinstated at the Revolution, he accompanied Principal Carstairs and a deputation as one of the Commissioners from the Kirk of Scotland to ad- dress the Sovereigns. Being a man of fine presence, it is related that the Queen and her maids of honour mistook him for the Principal, till the King set them 476 SIMSON. right by presenting Carstairs to them. The grandson, Robert, is said to have been the eldest of seventeen children; and the estate of Kirton Hill, which had been in the family for several generations, being incon- siderable, it was necessary for him, as well as his brothers, to be placed in some profession. The asser- tion is made in one account, written by a son of Professor Millar, and is likely to be correct, that he was intended for the medical profession, and being sent to Leyden studied under Boerhaave. He appears to have been at first intended for the Church, and to have changed his plan. Dr. Traill, however, says, that he was always intended for the Church, and that when the University of St. Andrew's in 1746 wished to confer on him a degree, they made him a Doctor of Medicine, because he had studied botany in his youth. Nothing can be more improbable than this story ; for to give him a degree they had only to make him Doctor of Laws, instead of taking a step which for ever threw discredit upon their medical honours. Mr. Millar must have heard the truth from his father and the other professors, who had the honour of knowing Dr. Simson personally, and never could have imagined or invented the circumstance of his studying under Boerhaave.* Of his early years we know little ; but that he was always extremely fond of reading is certain ; and he * The account which I have seen was in the late Earl of Buchan's possession, and was extended by matters collected when he himself studied at Glasgow. It seems by the mathematical appearance of it to have come from James Millar, himself one of the Professors. SIMSON. 477 must have had a considerable turn for mechanical pur- suits if the tradition in the neighbourhood of Kirton Hill be well founded, which ascribes to him the mak- ing, or at least designing and placing a dial of a curious form (which I have seen) on a neatly ornamented pe- destal in the garden of his father's house. At the usual early age of matriculation in Scotland, he was sent to the University of Glasgow, and he had there made con- siderable progress in his studies before the love of mathe- matical pursuits appeared to possess him. His atten- tion was directed to theology, to logic, to Oriental learning ; and in the latter he had made such progress, that a relation who taught the class having fallen ill, Sim son easily supplied his place for part of a session, the Scottish academical year. It was while engaged in theological studies that the mathematics first seized hold of his mind. He used in after life to relate how, wearied with the controversies to which his clerical studies led him, he would refresh himself with philo- sophical reading ; and not seldom finding himself there also tossed about by conflicting dogmas, he retired for peace and shelter to the certain science of necessary truth ; " and then," said he, " I always found myself refreshed with rest." It happened that no lecture or teaching of any kind was given by the professor who filled the mathematical chair, receiving its emoluments, and neglecting its duties, when Simson went to the University. But curiosity, a propensity ever strong in his nature through his whole life, made him wish to see what the science was, and he borrowed from a friend a copy of Euclid, the work which he was destined afterwards to give 478 SIMSON. forth in a perfection that has made all other editions of that great classic be forgotten. Over the elements of the science he pored assiduously and alone, with only the aid of suggestions occasionally given by a student some years older than himself; and the study falling in with his genius and his taste, he soon made himself master of the first six books, comprising plain geometry, and the eleventh and twelfth, treating of solids, those at least which are bounded by planes or by circular arches. But he did not neglect the other branches of science taught at the College ; and he also gave his attention to the literary parts of educa- tion, so well mastering the Latin and Greek languages as to become a learned and accurate scholar. It was in the mathematics, however, that he chiefly excelled ; and his accomplishments in that science becoming known to the professorial body (the Senatus Academi- cus), in whom is vested the patronage of the mathe- matical chair, and an early vacancy being foreseen, they offered him the succession in that event. Being then in his twenty-second year, he modestly declined to undertake so important a charge, but requested a year's delay, during which he might repair to London, and become more familiar with the science and its cul- tivators. We may hence perceive that there could then have been no one at all versed in the mathematics at Glasgow ; and the allowing so important a branch of science to remain for so many years untaught because the teacher who received the ample emoluments of the chair either could not or would not perform its duties, affords a sufficient commentary upon the great abuse likely to flow from vesting the patronage of a profes- SIMSON. 479 sorship in the colleagues of the teacher. I have known a professor's son appointed to the same chair, with few or no mathematical acquirements, because his father was much and justly respected among the mem- bers of the academical body. The same thing could not happen in Edinburgh, where the Crown or the magistrates have the patronage of all the professorships excepting one, and that is in the representative of the founder.* Simson repaired accordingly to London, where he be- came intimately acquainted, among others, with Jones the optician, with Henry Ditton of Christ's Hospital, under whose tuition he placed himself, with Carswell, above all, with Edmund Halley, then a captain in the Navy, afterwards so celebrated as Dr. Halley ; of whom he used to assert that " he had never known any other man of so acute and penetrating an under- standing, and of so pure a taste." From him he re- ceived much personal kindness, and what he had reason to value still more, the advice to prosecute his study of the Ancient Geometry, and attempt restoring its lost books. Halley made him a present of his copy of Pappus, with notes in his own hand. But though these accidental circumstances tended to direct his attention towards the scrupulous rigour as well as surpassing elegance of the Greek methods, it is a great mistake to suppose that he objected to the strictness of the modern analysis as inadequate. That he deemed its beauty inferior, and that he was right in so deem- ing, is certain ; but that he questioned the solidity of * Agriculture, in the Pulteney Family. 480 SIMSON. its foundations is wholly untrue. Not only did he always explain its principles to his pupils, though in a manner peculiar to himself, but he has left behind him a trea- tise demonstrating the fundamental laws of the cal- culus, and we now possess it in a printed form. Equally groundless is the notion that he questioned the sound- ness of the Newtonian Philosophy. He was not ena- bled to make Sir Isaac's acquaintance during his resi- dence in London ; but among those he lived with he constantly had seen him viewed with a peculiar ob- servance, and Halley in particular regarded him as hardly human, and his attainments in science as exalt- ing our species, while they ennobled himself, its rarest individual. Simson's copy of the ' Principia ' is fully noted in the margin with illustrations, showing that he entirely assented to the results of the investigations in the several propositions, and only wished to substi- tute certain steps in the demonstrations. Professor Robison has also related (Art. Simson, Encyc. Brit. xvii. 505) his constant remark, that the celebrated proposition in the ' Principia ' on inverse centripetal forces " was the most important ever delivered to man- kind in the mixed mathematics." While he remained in London the expected vacancy occurred in the chair at Glasgow, and he returned thither. The professors appear to have thought it right that their former neglect of duty should be com- pensated by a very superfluous show of more than need- ful attention to it on this occasion ; for they required Mr. Simson to give proof of his fitness to succeed the sinecure incumbent, by solving a geometrical problem, of which it is all but absolutely certain that they could SIMSON. 481 have no knowledge, unless the question was so simple as to afford no test of the candidate's capacity. He pro- duced, however, what they might better understand, testimonials from known mathematicians in London, a farther proof of there being no cultivators of the science then resident in the metropolis of Scottish manufactures. He was thus appointed professor in 1711, and im- mediately began the regular course of instruction, which he continued for half a century. He taught two classes five days a week for seven months every year. Though geometry was his own favourite study, he was a thorough algebraist also, and so well versed in mathematical science at large, that he gave lectures on its general history. With astronomy, and the other branches of the mixed mathematics, he was no less conversant ; and in various departments of physics he had made great progress. In botany he was parti- cularly expert; it formed his chosen amusement dur- ing the walks in which he relaxed from his severer studies. His curiosity led him into other paths of science. To logic, that of the schools, he had given so much attention, that of a tract, composed by him upon its principles, some portion remains among his papers ; it is said to possess great merit ; and doubtless this study was congenial to the one which he mainly pursued, nor could it fail to aid his strict and luminous method of both defining, demonstrating, and explain- ing the truths of geometry. Among his colleagues, after he had been professor a few years, were some of the most eminent men of that, or indeed of any age. Moore, professor of Greek, and author of the admirable and elegant 'Grammar;' 482 SIMSON. Hutcheson, and Adam Smith, successively teachers of moral philosophy ; Cullen, the celebrated physician ; Black, the great founder of modern chemistry — all taught while Simson flourished ; Millar only became professor of law at the close of the brilliant period now referred to, and Robison succeeded Black in 1761, soon after Simson's resignation. But a teacher's influence is nothing in surrounding himself with illustrious colleagues: of great pupils he may more easily obtain a following. Of these, Dr. Simson had some whose names are still honoured among mathematicians. Williamson, afterwards his assistant in the class, a man of great promise, whose early death at the Factory of Lisbon, to which he was chaplain, alone prevented him from following with distinction his master's footsteps ; Scott, preceptor to George III. when Prince of Wales, afterwards a Com- missioner of Excise in London, perhaps the most accomplished of all amateur mathematicians who never gave their works to the world ; Traill, author of the excellent elementary treatise of algebra, of a very learned and exceedingly ill-written, indeed, hardly readable, life of his friend and teacher, but a man of great capacity for science, entirely extinguished, to- gether with his taste for its pursuits (as Professor Playfair used to lament), by the sinecure emoluments of the Irish Church ; but above all, Matthew Stewart, Simson's favourite pupil, and whose suggestions, and indeed contributions, he records in his works with appropriate eulogy, as he does on one occasion an in- genious theorem of Traill — these were among his scholars, and were, with Robison, the most dis- tinguished of their number. His method of lecturing SIMSON. 483 is, by both of the pupils who have written his history, Professor Robison and Dr. Traill, described as singu- larly attractive. His explanations were perfectly clear, and were delivered with great spirit, as well as with the pure taste which presided over all his mathe- matical processes. His elocution was distinct and natural, his whole manner at once easy and impres- sive. He did not confine his tuition to the chair, but encouraged his pupils to propound their difficulties in private, and was always accessible to their demands of assistance and advice. Hence the affectionate zeal with which they followed his teaching and ever cherished his memory. Successful, however, as he proved in the chair, his genius was bent to the diligent investigation of truth in the science of which he was so great a master. The ancient geometry, that of the Greeks of which I have spoken, early fixed his attention and occupied his mind by its extraordinary elegance, by the lucid clear- ness with which its investigations are conducted, by the exercise which it affords to the reasoning faculties, and above all, by the absolute rigour of its demon- strations. He never undervalued modern analysis ; it is a great mistake to represent him as either disliking its process, or insensible to its vast importance for the solution of questions which the Greek analysis is wholly incapable of reaching. But he considered it as only to be used in its proper sphere: and that sphere he held to exclude whatever of geometrical investigation can be, with convenience and elegance, carried on by purely geometrical methods. The appli- cation of algebra to geometry, it would be ridiculous 2 i 2 484 SIMSOX. to suppose that either he or his celebrated pupil Stewart disliked or undervalued. That application forms the most valuable service which modern analysis has rendered to science. But they did object, and most reasonably and consistently, to the introduction of algebraic reasoning wherever the investigation could, though less easily, yet far more satisfactorily, be performed geometrically. They saw, too, that in many instances the algebraic solution leads to con- structions of the most complex, clumsy, unmanage- able kind, and therefore must be, in all these instances, reckoned more difficult, and even more prolix than the geometrical, from the former being confined to the expression of all the relations of space and position, by magnitudes, by quantity and number, (even after the arithmetic of sines had been introduced,) while the latter could avail itself of circles and angles directly. They would have equally objected to car- rying geometrical reasoning into the fields peculiarly appropriate to modern analysis ; and if one of them, Stewart, did endeavour to investigate by the ancient geometry physical problems supposed to be placed beyond its reach — as the sun's distance, in which he failed, and Kepler's problem, in which he marvel- lously succeeded, that of dividing the elliptical area in a given ratio by a straight line drawn from one focus — this is to be taken only as an homage to the undervalued potency of the Greek analysis, or at most, as a feat of geometrical force, and by no means as an indication of any wish to substitute so imperfect, however beautiful, an instrument, for the more powerful, though more ordinary one of the calculus which " alone can work SIMSON. 485 great marvels." At the same time, and with all the necessary confession of the merits of the modern method, it is certain that those geometricians would have regarded the course taken hy some of its votaries in more recent times as exceptionable, whether with a view to clearness or to good taste : a course to the full as objectionable as would be the banishing of alge- braical and substituting of geometrical symbols in the investigations of the higher geometry. La Place's great work, the ' Mecanique Celeste,' and La Grange's ' Meca- nique Analytique,' have treated of the whole science of dynamics and of physical astronomy, comprehending all the doctrine of trajectories, dealing with geome- trical ideas throughout, and ideas so purely geometrical that the algebraic symbols, as far as their works are concerned, have no possible meaning apart from lines, angles, surfaces ; and yet in their whole compass they have not one single diagram of any kind. Surely, we may ask if 4-v doc- +dy2 , 7 0 -, / du \ can pos- * dii J dx°d ( -?- \ \d*) sibly bear any other meaning than the tangent and the radius of curvature of a curve line : that is, a straight line touching a curve, and a circle whose curvature is that of another curve where they meet ; any meaning, at least, which can make it material that they should ever be seen on the page of the analyst. These expressions are utterly without sense, except in reference to geometrical con- O 486 SIMSON. siderations ; for although x and y are so general that they express any numbers, any lines, nay, any ideas, any rewards or punishments, any thoughts of the mind, it is manifest that the square of the differential of a thought, or the differential of the differential of a reward or punishment, has no meaning ; and so of every thing else but of the very tangent or osculating circle's radius : consequently the generality of the symbols is wholly useless ; the particular case of two lines being the only thing to which the expressions can possibly be meant to apply. Why, then, all geometrical symbols should be so carefully avoided when we are really treating of geometrical examples and geometrical ideas, and of these alone, seems hard to understand. As the exclusive lovers of modern analysis have frequently and very erroneously suspected the ancients of possessing some such instrument, and concealing the use of it by giving their demonstrations synthe- tically after reaching their conclusions analytically, so some lovers of ancient analysis have supposed that Sir Isaac Newton obtained his solutions by algebraic investigations, and then covered them with a synthetic dress : among others, Dr. Simson leant to this opinion respecting the ' Principia.' He used to say that he knew this from Halley, by whose urgent advice Sir Isaac was induced to adopt the synthetic form of demonstration, after having discovered the truths ana- lytically. Machin is known to have held the same language ; he said that the ' Principia' was algebra in disguise. Assuredly, the probability of this is far greater than that of the ancients having possessed and kept secret the analytical process of modern times. In the preface to his ' Loci Plani,' Dr. Simson fully refutes SIMSON. 487 this notion respecting the ancients : a notion which, among others, no less a writer than Wallis had strongly maintained.* Dr. Simson is by some supposed to have had at one time the intention of discussing at large the proper limits of the ancient and the modern analysis in the investigation of mathematical truths. This no doubt appears to be the meaning of a passage in his preface to the Conic Sections : " In quantum^ autem differat ana- lysis geometrica ab ea quse calculo instituitur algebraico, atque ubl hcec aut ilia sit usurpanda, alias disseren- dum? Professor Robison thought he had seen a por- tion of the work ; but he must have been mistaken ; for in answer to Mr. Scott's letter urging him to pub- lish this, and referring to the preface in the words just cited, he expressly says, that though this passage might well mislead, he never meant, except by " blundering in the expression, anything of the kind, had no paper, and never wrote anything about the matter :" and this was written in 1764, four years before his death, and eleven or twelve years after Professor Robison attended his class. Nothing can be more clear than that between 1764 and his death, in 1768, he never attempted any work of moment ; much more any work such as the one in * Algebra Prsef. " Hanc Graecos olim habuisse non est quod dubitemus ; sed studio celatam, nee temere propalandam. Ejus effectus (utut clam celatae) satis conspicui apud Archimedem, Apollonium, aliosque." It is strange that any one of ordinary reflection should have overlooked the utter impossibility of all the geometricians in ancient times keeping the secret of an art which must, if it existed, have been universally known in the mathematical schools, and at a time when every man of the least learning or even of the most ordinary education was taught geometry. 488 SIMSON. question, which we thus have his own authority for say- ing he never had previously entertained any intention of composing. It is much to be lamented that he never did give such a work to the world. His thoughts had often been very profoundly directed to the subject ; and no one was so well fitted to handle it with the learning and with the judgment wrhich its execution required. That he did not undervalue algebra and the calculus to which it has given rise, appears from many circum- stances— among others, from what has already been stated ; it appears also from this, that in many of his manuscripts there are found algebraical formulas for propositions which he had investigated geometrically. Maclaurin consulted him on the preparation of his admirable work, the ' Fluxions/ and received from him copious suggestions and assistance. Indeed, he adopted from him the celebrated demonstration of the fluxion (or differential) of a rectangle.* But Simson's whole mind, when left to its natural bent, was given to the beauties of the Greek geometry ; and he had not been many months settled in his academical situation when he began to follow the advice which Halley had given him, as both calculated, he said, to promote his own reputation, and to confer a lasting benefit upon the science cultivated by them both with an equal de- votion. It is even certain that the obscure and most difficult subject of Porisms very early occupied his thoughts, and was the field of his researches, though to the end of his life he never had made such progress in * Book i. ch. ii. prop. 3. SIMSON. 489 the investigation as satisfied himself. Before 1715, three years after he began his course of teaching, he was deeply engaged in this inquiry ; but he only re- garded it as one branch of the great and dark subject which Halley had recommended to his care. After he had completely examined, corrected, and published, with most important additions, the Conies of Apollo- nius, which happily remain entire, but which, as we have seen, had been most inelegantly and indeed alge- braically given by De la Hire, L'Hopital, and others, to restore the lost books was his great desire, and formed the grand achievement which he set before his eyes. We have already shown how scanty the light was by which his steps in this path must be guided. The introduction to the seventh book of Pappus contained the whole that had reached our times to let us know the contents of the lost works. Some of the sum- maries which that valuable discourse contains are suffi- ciently explicit, as those of the Loci Plani and the Determinate Section. Accordingly, former geometri- cians had succeeded in restoring the Loci Plani, or those propositions which treat of loci to the circle and rectilinear figures. They had, indeed, proceeded in a very unsatisfactory manner ; Schooten, a Dutch mathematician of great industry and no taste, had given purely algebraic solutions and demonstrations. Fermat, one of the greatest mathematicians of the seventeenth century, had proceeded more according to the geometrical rules of the ancients ; but he had kept to general solutions, and neither he nor Schooten had given the different cases, according as the data in each proposition were varied, so that their works were nearly 490 SIMSON. useless in the solution of problems, the great purpose of Apollonius, as of all the authors of the TOTTO? avaXvojmevov — the thirty-three ancient books. As for the analysis, it was given by neither, unless, indeed, Schooten's algebra is to be so termed : Fermat's de- monstrations were all synthetical. His treatise, though written as early as 1629, was only published among his collected works in 1670. Schooten's was published among his ' Exercitationes Mathematicse' in 1657. Of the field thus left open Dr. Simson took possession, and he most successfully cultivated every corner of it. Nothing is left without the most full discus- sion ; all the cases of each proposition are thoroughly investigated. Many new truths of great importance are added to those which had been unfolded by the Greek philosopher. The whole is given with the per- fect precision and the pure elegance of the ancient analysis ; and the universal assent of the scientific world has even confessed that there is every reason to consider the restored work as greatly superior to the lost original. The history of this excellent treatise shows in a striking manner the cautious and modest nature of its author. He had completed it in 1738 ; but, unsatisfied with it, he kept it by him for eight years. He could not bring himself to think that he had given the "ipsissimse propositiones of Apollonius in the very order and spirit of the original work." He was then persuaded to let the book appear, and it was published in 1746. His former scruples and alarms recurred ; he stopped the publication ; he bought up the copies that had been sold ; he kept them three years longer SIMSON. 491 by him ; and it was only in 1749 that the work really appeared. Thus had a geometrician complied with the rule prescribed by Horace for those whose writings have no standard by which to estimate their merits with exactness. In the meantime he had extended his researches into other parts of the subject. Among the rest he had restored and greatly extended the work on Determi- nate Section, or the various propositions respecting the properties of the squares and rectangles of seg- ments of lines passing through given points. There is no doubt that the prolixity, however elegant, with which the ancients treated this subject, is somewhat out of proportion to its importance ; and as it is pecu- liarly adapted to the algebraical method, presenting, indeed, little difficulty to the analyst, the loss of the Pergsean treatise is the less to be deplored, and its re- storation was the less to be desired. Apollonius had even thought it expedient to give a double set of solu- tions ; one by straight lines, the other by semicircles. Dr. Simson's restoration is most full, certainly, and contains many and large additions of his own. It fills above three hundred quarto pages. His predecessors had been Snellius, whose attempt, published in 1608, was universally allowed to be a failure ; and Anderson, a professor of Aberdeen, whose work, in 1612, was much better, but confined to a small part only of the subject. About the time that Dr. Simson finally published the Loci Plani, he began his great labour of giving a correct and full edition of the Elements. The manner in which this has been accomplished by him is well 492 SIMSON. known. The utmost care was bestowed on the revi- sion of the text; no pains were spared in collating editions ; all commentaries were consulted ; and the elegance and perfect method of the original has been so admirably preserved, that no rival has ever yet risen up to dispute with Simson's Euclid the possession of the schools. The time bestowed on this useful work was no less than nine years. It only was published in 1758. To the second edition, in 1762, he added a similarly correct edition of the Data, comprising several very valuable original propositions of his own, of Mr. Stewart, and of Lord Stanhope, together with two excellent problems to illustrate the use of the Data in solutions. We thus find Dr. Simson employed in these various works which he successively gave to the world, elaborated with infinite care, and of which the fame and the use will remain as long as the mathematics are cultivated, some of them delighting students who pursue the science for the mere speculative love of contemplating abstract truths, and the gratification of following the rigorous proofs peculiar to that science ; some for the instruction of men in the elements, which are to form the foundation of their practical applications of geometry. But all the while his mind never could be wholly severed from the speculation which had in his earliest days riveted his attention by its curious and singular nature, and fired his youthful ambition by its difficulty, and vanquished all his predecessors in their efforts to master it. We have seen that as early as 1715 at the latest, probably much earlier, the obscure subject of Porisms had engaged his thoughts ; and soon SIMSOX. 493 after, his mind was so entirely absorbed by it that he could apply to no other investigation. The extreme imperfection of the text of Pappus, the dubious nature of his description, his rejection of the definition which appeared intelligible, his substituting nothing in its place except an account so general that it really con- veyed no precise information, the hiatus in the account he subjoins of Euclid's three books, so that even with the help of the lemmas related to these propositions of the lost work, no clear or steady light could be de- scjied to guide the inquirer — for the first porism of the first book alone remained entire, the general porism being given wholly truncated (mancum et im- perfectum) — all seemed to present obstacles wholly insurmountable, and after various attempts for years he was fain to conclude with Halley that the mystery belonged to the number of those which can never be penetrated. He lost his rest in the anxiety of this inquiry ; sleep forsook his couch ; his appetite was gone ; his health was wholly shaken ; he was com- pelled to give over the pursuit ; he was " obliged," he says, " to resolve steadily that he never more should touch the subject,- and as often as it came upon him he drove it away from his thoughts."* It happened, however, about the month of April, 1722, that while walking on the banks of the Clyde with some friends, he had fallen behind the company ; and musing alone, the rejected topic found access to * " Firmiter animum induxi hsec nunquam in posterum investi- gare. Unde quoties menti occurrebant, f oties eas arcebam." — (Op. Eel. 320. Prsef. ad Porismata.) 494 SIMSON. his thoughts. After some time a sudden light broke in upon him ; it seemed at length as if he could descry something of a path, slippery, tangled, interrupted, but still practicable, and leading at least in the direction towards the object of his research. He eagerly drew a figure on the stump of a neighbouring tree with a piece of chalk ; he felt - assured that he had now the means of solving the great problem ; and although he afterwards tells us that he then had not a sufficiently clear notion of the subject (eo tempore Porismatum naturam non satis compertamhabebam),* yet he accom- plished enough to make him communicate a paper upon the discovery to the Royal Society, the first work he ever published (Phil. Trans, for 1723). He was wont in after life to show the spot on which the tree, long since decayed, had stood. If peradventure it had been preserved, the frequent lover of Greek geometry would have been seen making his pilgrimage to a spot consecrated by such touching recollections. The graphic pen of Montucla, which gave such interest to the story of the first observation of the transit of Venus by Horrox in Lancashire, and to the Torricellian experiment, f is alone wanting to clothe this passage in colours as vivid and as unfading. This great geometrician continued at all the inter- vals of his other labours intently to investigate the subject on which he thus first threw a steady light. His first care upon having made this discovery was to extend the particular propositions until he had obtained Op. Rel. 320. | Hist, de Math. vol. i. SIMSON. 495 the general one. A note among his memoranda ap- pears to have been made, as was his custom, of the date at which he succeeded in any of his investiga- tions.*— " Hodie hsec de porismatis inveni, R. S., 23 April 1722." Another note, 27th April, 1722, shows that he had then obtained the general proposition ; he afterwards communicated this to Maclaurin when he passed through Glasgow on his way to France ; and on his return he communicated to Dr. Simson with- out demonstration a proposition concerning conies derived from it, which led his friend to insert some important investigations in his Conic Sections. In 1723 the publication of his paper took place in the Philosophical Transactions ; it is extremely short, and does not appear to contain all that the author had communicated ; for we find this sentence inserted before the last portion of the paper : — " His adjecit clarissimus professor propositiones duas sequentes libri primi Porismatum Euclidis, a se quoque restitutas." The paper contains the first general proposition and its ten cases, and then the second with its cases. No general description or definition is given of Porisms ; and it is plain that his mind was not then finally made up on this obscure subject, although he had obtained a clear view of it generally. * In one there is this note upon the solution of a problem of tactions, — " Feb. 9, 1734 : — Post horam primam ante meridiem ;" and much later in life we find the same particularity in marking the time of discovery. His birthday was October 14, and having solved a problem on that day, 1764, he says — HOctobr. 1764. Deo Opt. Max. benignissimo Servaton 14 Octobr. 1687. Laus et gloria. 77 (sell AnnojEtatis.) 496 SIMSON. At what time his knowledge of the whole became matured we are not informed ; but we know that his own nature was nice and difficult on the subject of his own works ; that he never was satisfied with what he had accomplished ; and he probably went on making constant additions and improvements to his work. Often urged to publish, he as constantly refused ; in- deed he would say that he had done nothing, or next to nothing, which was in a state to appear before the world ; and moreover, he very early began to appre- hend a decay of his faculties, from observing his recol- lection of recent things to fail, as is very usual with all men ; for as early as 1751, we find him giving this as a reason for declining to undertake a work on Lord Stanhope's recommendation, when he was only in his sixty-fifth year. Thus, though he at first used to say he had nothing ready for publication, he afterwards added, that he was too old to complete his work satis- factorily. In his earlier days he used occasionally to affect a kind of odd mystery on the subject, and when one of his pupils (Dr. Traill) submitted to him some propositions, which he regarded as porisms, Dr. Sim- son would neither admit nor deny that they were such, but said with some pleasantry, " They are propositions." One of them, however, he has given in his work as a porism, and with a complimentary reference to its ingenious and learned author. Thus his life wore away without completing this great work, at least without putting it in such a con- dition as satisfied himself. It was left among his MSS., and by the judicious munificence of a noble geometri- cian, the liberal friend of scientific men, as well as the SIMSON. 497 successful cultivator of science, Earl Stanhope,* it was, after his death, published, with his restoration of Apollonius' treatise De Sectione determinata, a short paper on Logarithms, and another on the Method of Limits geometrically demonstrated, the whole forming a very handsome quarto volume; of which the Porisms occupies nearly one-half, or 277 pages. This work is certainly the master-piece of its distin- guished author. The extreme difficulty of the subject was increased by the corruptions of the text that re- mains in the only passage of the Greek geometers which has reached us, the only few sentences in which any mention whatever is made of porisms. This passage is contained in the preface or introduction to the seventh book of Pappus, which we have already had occasion to cite. But this was by far the least of the difficul- ties which met the inquirer after the hidden treasure, the restorer of lost science, though Albert Girard thought or said, in 1635, that he had restored the Po- risms of Euclid. As we have seen, no trace of his labours is left ; and it seems extremely unlikely that he should have really performed such a feat and given no proofs of it. H alley, the most learned and able of Dr. Simson's predecessors, had tried the subject, and tried it in vain. He thus records his failure : — " Hac- tenus Porismatum descriptio nee mihi mtellecta nee lectori profutura." These are his words, in a preface to a translation which he published of Pappus's seventh book, much superior in execution to that of Commandini. But this eminent geometrician was * Grandfather of the present Earl. 2 K 498 SIMSON. much more honest than some, and much more safe and free from mistake than others who touched upon the subject which occupied all students of the ancient analysis. He was far from pretending, like Girardus, to have discovered that of which all were in quest. But neither did he blunder like Pemberton, whom we find, the very year of Simson's first publication, actually saying in his paper on the Rainbow — "For the greater brevity I shall deliver them (his propositions) in the form of porisms, as, in my opinion, the ancients called all propositions treated by analysis only" (Philo- sophical Transactions, 1723, p. 148) ; and, truth to say, his investigation is not very like ancient analysis either. The notion of D'Alembert, somewhat later, has been alluded to already ; he imagined porisms to be synonymous with lemma, misled by an equivocal use of the word in some passages of ancient authors, if indeed he had ever studied any of the writers on the Greek geometry, which, from what I have stated be- fore, seems exceedingly doubtful. But the most extra- ordinary, and indeed inexcusable ignorance of the sub- ject is to be seen in some who, long after Simson's paper had been published, were still in the dark ; and though that paper did not fully explain the matter, it yet ought to have prevented such errors as these fell into. Thus Castillon, in 1761, showed that he con- ceived porisms to be merely the constructions of Eu- clid's Data. If this were so, there might have been some truth in his boast of having solved all the Porisms of Euclid ; and he might have been able to perform his promise of soon publishing a restoration of those lost books. SIMSON. 499 It is remarkable enough that before Halley's at- tempts and their failure, candidly acknowledged by himself, Fermat had made a far nearer approach to a solution of the difficulty than any other of Simson's predecessors. That great geometrician, after fully admitting the difficulty of the subject, and asserting* that, in modern times, porisms were known hardly even by name, announces somewhat too confidently, if not somewhat vaingloriously, that the light had at length dawned upon him,')' and that he should soon give a full restoration of the whole three lost books of Euclid. Now the light had but broke in by a small chink, as a mere faint glimmering, and this restora- tion was quite impossible, inasmuch as there remained no account of what those books contained, except- ing a very small portion obscurely mentioned in the preface of Pappus, and the lemmas given in the course of the seventh book, and given as subservient to the resolution of porismatic questions. Never- theless Fermat gave a demonstration of five propo- sitions, " in order," he says, " to show what a porism is, and to what purposes it is subservient." These propositions are, indeed, porisms, though their several enumerations are not given in the true porismatic form. Thus, in the most remarkable of them, the fifth, he gives the construction as part of the enuncia- * " Intentata ac velut disperata Porismatum Euclideea doctrina. — Geometric! (sevi recentioris) nee vel de nomine cognovertmt, aut quod esset solummodo sunt suspicati." — (Var. Opera, p. 166.) f " Nobis in tenebris dudum csecutientibus, tandem se (Natura Porismatum) clara ad videndum obtulit, et pura per noctem luce refulsit.'1 — (Epist. ib.) 2K2 500 SIMSON. tion. So far, however, a considerable step was made ; but when he comes to show in what manner he dis- covered the nature of his porisms, and how he defines them, it is plain that he is entirely misled by the erroneous definition justly censured in the passage of Pappus already referred to. He tells us that his pro- positions answer the definition ; he adds that it reveals the whole nature of porisms ; he says that by no other account but the one contained in the definition, could we ever have arrived at a knowledge of the hidden value;* and he shows how, in his fifth proposition, the porism flows from a locus, or rather he confounds porisms with loci, saying porisms generally are loci, and so he treats his own fifth proposition as a locus, and yet the locus to a circle which he states as that from which his proposition flows has no connexion with it, according to Dr. Simson's just remark (' Opera Reliqua,' p. 345). That the definition on which he relies is truly imperfect, appears from this : there could be no algebraical porism, were every porism connected with a local theorem. But an abundant variety of geometrical porisms can be referred to, which have no possible connexion with loci. Thus, it has never been denied that most of the Propositions in the Higher Geometry, which I investigated in 1797, were porisms, yet many of them were wholly unconnected with loci ; as that affirming the possibility of describing an hyper- bola which should cut in a given ratio all the areas of the parabolas lying between given straight lines. f * Var. Op., p. 118. | Phil. Trans., 1798, p. 111. SIMSON. 501 Here the locus has nothing to do with the solution, as if the proposition were a kind of a local theorem : it is only the line dividing the curvilineal areas, and it divides innumerable such areas. Professor Playfair, who had thoroughly investigated the whole subject, never in considering this proposition doubted for a moment its being most strictly a porism. Therefore, although Fermat must be allowed to have made a considerable step, he was unacquainted with the true nature of the porism ; and instead of making good his boast that he could restore the lost books, he never even attempted to restore the investi- gation of the first proposition, the only one that re- mains entire. A better proof can hardly be given of the difficulty of the whole subject.* Indeed it must be confessed that Pappus's account of it, our only source of knowledge, is exceedingly obscure, all but the panegyrics which, in a somewhat tanta- lizing manner, he pronounces upon it. " Collectio," says he, " curiosissima multarum rerum spectantium ad resolutionem difficiliorum et generaliorurn problema- tum" (lib. vii., Proem). His definition already cited is, as he himself admits, very inaccurate ; because the * The respect due to the great name of Fermat, a venerable magistrate and most able geometrician, is not to be questioned. He was, indeed, one of the first mathematicians of the age in which he flourished, along with the Robervals, the Harriots, the Descartes. How near he approached the differential calculus is well known. His correspondence with Roberval, Gassendi, Pascal, and others, occupies ninety folio pages of his posthumous works, and contains many most ingenious, original, and profound observations on va- rious branches of science. 502 SIMSON. connexion with a locus is not necessary to the poris- matic nature, although it will very often exist, inas- much as each point in the curve having the same re- lation to certain lines, its description will, in most cases, furnish the solution of a problem, whence a porism may be deduced. Nor does Pappus, while ad- mitting the inaccuracy of the definition, give us one of his own. Perhaps we may accurately enough define a porism to be the enunciation of the possibility of finding that case in which a determinate problem be- comes indeterminate, and admits of an infinity of solutions, all of which are given by the statement of the case. For it appears essential to the nature of a porism that it should have some connexion with an indetermi- nate problem and its solution. I apprehend that the poristic case is always one in which the data become such that a transition is made from the determinate to the indeterminate, from the problem being capable of one or two solutions, to its being capable of an infinite number. Thus it would be no porism to affirm that an ellipse being given, two lines may be found at right angles to each other, cutting the curve, and being in a proportion to each other which may be found : the two lines are the perpendiculars at the centre, and are of course the two axes of the ellipse ; and though this enunciation is in the outward form of a porism, the proposition is no more a porism than any ordinary pro- blem ; as that a circle being given a point may be found from whence all the lines drawn to the circumference are equal, which is merely the finding of the centre. But suppose there be given the problem to inflect two SIMSON. 503 lines from two given points to the circumference of an ellipse, the sum of which lines shall be equal to a given line, the solution will give four lines, two on each side of the transverse axis. But in one case there will be innumerable lines which answer the conditions, namely, when the two points are in the axis, and so situated that the distance of each of them from the farthest ex- tremity of the axis is equal to the given line, the points being the foci of the ellipse. It is, then, a porism to affirm that an ellipse being given, two points may be found such that if from them be inflected lines to any point whatever of the curve, their sum shall be equal to a straight line which may be found ; and so of the Cassinian curve, in which the rectangle under the in- flected lines is given. In like manner if it be sought in the cubic hyperbola (y x°~=oc — a) to inflect from two given points in a given straight line, two lines to a point in the curve, so that the tangent to that point shall, with the two points and the ordinate, cut the given line in harmonical ratio ; this, which is only capable of one solution in ordinary cases, becomes capable of an infinite number when the two points are in the axis, one of them the curve's apex, and the other at the distance equal to the given line a from the apex ; for in that case every tangent that can be drawn, and every ordinate, cut the given line har- monically with the curve itself and the given point.* This curve has many curious and elegant properties : for ex- ample— All the lines which can be drawn in every direction from any point out of the curve are cut harmonically by the tangent, the ordinate, and the lines joining the two given points. This 504 SIMSON. Dr. Simson's definition is such that it connects itself with an indeterminate case of some problem solved, but it is defective, in appearance rather than in reality, from seeming to confine itself to one class of porisms. This appearance arises from using the word "given" (data or datum) in two different senses, both as describing the hypothesis and as affirming the possibility of finding the construction so as to answer the conditions. This double use of the word, indeed, runs through the book, and though purely classical, is yet very inconvenient ; for it would be much more distinct to make one class of things those which are assuredly data, and the other, things which may be found. Nevertheless, as his definition makes all the innumerable things not given have the same relation to those which are given, this should seem to be a limitation of the definition not necessary to the poristic nature. Pappus's definition, or rather that which he says the ancients gave, and which is not exposed to the objection taken by him to the modern one, is really no definition at all ; it is only that a porism is something between a theorem and a problem, and in which, instead of anything being proposed to be done, or to be proved, something is proposed to be investigated. might be called the Harmonical Curve, did not another of the 12th order rather merit that name, which has its axis divided harmoni- cally by the tangent, the normal, the ordinate, and a given point in the axis. Its differential equation is 2 d y*+d x*=— — - — -' oc which is reducible, and its integral is an equation of the 12th order. There is another Harmonical Curve, also, a transcendental one, in which chords vibrate isochronously. SIMSON. 505 This is erroneous, and contrary to the rules of logic from its generality ; it is, as the lawyers say, void for uncertainty. The modern one objected to by Pappus is not uncertain ; it is quite accurate as far as it goes ; but it is too confined, and errs against the rules of logic by not being coextensive with the thing proposed to be defined. The difficulty of the subject has been sufficiently shown from the extreme conciseness and the many omissions, the almost studied obscurity, of the only account of it which remains, and to this must cer- tainly be added the corruption of the Greek text. The success which attended Dr. Simson's labours in restoring the lost work, as far as that was possible, and, at any rate, in giving a full elucidation of the nature of porisms, now, for the first time, disclosed to mathe- maticians, is, on account of those great difficulties by which his predecessors had been baffled, the more to be admired. But there is one thing yet more justly a matter of wonder, when we contrast his proceedings with theirs. The greater part of his life, a life ex- clusively devoted to mathematical study, had been passed in these researches. He had very early become possessed of the whole mystery, from other eyes so long concealed. He had obtained a number of the most curious solutions of problems connected with porisms, and was constantly adding to his store of porisms and of lemmas subservient to their investi- gation. For many years before his death, his work had attained, certainly the form, if not the size, in which we now possess it. Yet he never could so far satisfy himself with what has abundantly satisfied every one else, as to make it public, and he left it un- 506 SIMSON. published among his papers when he died. Nothing can be more unlike those who freely boasted of having discovered the secret, and promised to restore the whole of Euclid's lost books. It is as certain that the secret was never revealed to them as it is that neither they nor any man could restore the books. But how speedily would the Castillons, the Alberts, even the Fermats, have given their works to the world had they become possessed of such a treasure as Dr. Simson had found ! Yet though ready for the press, and with its preface composed, and its title given in minute particularity, he never could think that he had so far elaborated and finished it as to warrant him in finally resolving on its publication. There needs no panegyric of this most admirable performance. Its great merit is best estimated by the view which has been taken of the extraordinary difficulties overcome by it. The difficulty of some investigations — the singular beauty of the propositions, a beauty peculiar to the porism from the wonderfully general relations which it discloses — the simplicity of the combinations — the perfect elegance of the demon- strations— render this a treatise in which the lovers of geometrical science must ever find the purest delight. Beside the general discussions in the preface, and in a long and valuable scholium after the sixth propo- sition, and an example of algebraical porisms, Dr. Sim- son has given in all ninety-one propositions. Of these four are problems, ten are loci, forty- three are theorems, and the remaining thirty-four are porisms, including four suggested by Matthew Stewart, and the five of Fermat improved and generalized ; there are, besides, four lemmas and one porism suggested SIMSON. 507 by Dr. Traill, when studying under the Professor. There may thus be said to be in all ninety-eight pro- positions. The four lemmas are propositions ancillary to the author's own investigations ; for many of his theorems are the lemmas preserved by Pappus as an- cillary to the porisms of Euclid. In all these investigations the strictness of the Greek geometry is preserved almost to an excess ; and there cannot well be given a more remarkable illus- tration of its extreme rigour than the very outset of this great work presents. The porism is, that a point may be found in any given circle through which all the lines drawn cutting its circumference and meeting a given straight line shall have their segments within and without the circle in the same ratio. This, though a beautiful proposition, is one very easily demonstrated, and is, indeed, a corollary to some of those in the ' Elements/ But Dr. Simson prefixes a lemma : that the line drawn to the right angle of a triangle from the middle point of the hypotenuse, is equal to half that hypotenuse. Now this follows, if the segment containing the right angle be a semi- circle, and it might be thought that this should be assumed only as a manifest corollary from the pro- position, or as the plain converse of the proposition, that the angle in a semicircle is a right angle, but rather as identical with that proposition ; for if we say the semicircle is a right-angled segment, we also say that the right-angled segment is a semicircle. But then it might be supposed that two semicircles could stand on one base : or, which is the same thing, that two perpendiculars could be drawn from one 508 SIMSON. point to the same line ; and as these propositions had not been in the elements, (though the one follows from the definition of the circle, and the other from the theorem that the three angles of a triangle are equal to two right angles,) and as it might be supposed that two or more circles, like two or more ellipses, might be drawn on the same axis, therefore the lem- ma is demonstrated by a construction into which the centre does not enter. Again, in applying this lemma to the porism (the proportion of the segments given by similar triangles), a right angle is drawn at the point of the circumference, to which a line is drawn from the extremity of a perpendicular to the given line ; and this, though it proves that perpendicular to pass through the centre, unless two semicircles could stand on the same diameter, is not held sufficient ; but the analysis is continued by help of the lemma to show that the perpendicular to the given line passes through the centre of the given circle, and that therefore the point is found. It is probable that the author began his work with a simple case and gave it a peculiarly rigorous investigation in order to explain, as he im- mediately after does clearly in the scholium already referred to, the nature of the porism, and to illustrate the erroneous definitions of later times (veoreptKoi) of which Pappus complains as illogical. Of porisms, examples have been now given both in plain geometry, in solid, and in the higher : that is, in their connexion both with straight lines and circles, with conic sections, and with curves of the third and higher orders. Of an algebraical porism it is easy to give examples from problems becoming inde- SIMSON. 509 terminate ; but these propositions may likewise arise from a change in the conditions of determinate pro- blems. Thus, if we seek for a number, such that its multiple by the sum of two quantities shall be equal to its multiple by the difference of these quantities, together with twice its multiple by a third given quantity, we have the equation (« + 6) x=(a — &) x+ 2co? and 2b^=2ca: ; in which it is evident, that if c=bt any number whatever will answer the conditions, and thus we have this porism : Two numbers being given a third may be found, such that the multiple of any number whatever by the sum of the given numbers, shall be equal to its multiple by their differences, together with half its multiple by the num- ber to be found. That number is in the ratio of 4 : 3 to the lesser given number. There are many porisms also in dynamics. One relates to the centre of gravity which is the poris- matic case of a problem. The porism may be thus enunciated ; — Any number of points being given, a point may be found such, that if any straight line whatever be drawn through it, the sum of the per- pendiculars to it from the points on one side will be equal to the sum of the perpendiculars from the points on the other side. That point is consequently the centre of gravity : for the system is in equilibrium by the proposition. Another is famous in the his- tory of the mixed mathematics. Sir Isaac Newton, by a train of most profound and ingenious investi- gation, reduced the problem of finding a comet's place from three observations (a problem of such difficulty, that he says of it, " hocce problema longe difficilimum 510 SIMSON. omnimodo aggressus,"*) to the drawing a straight line through four lines given by position, and which shall be cut by them in three segments having given ratios to each other. Now his solution of this problem, the corollary to the twenty-seventh lemma of the first book, has a porismatic case, that is, a case in which any line that can be drawn through the given lines will be cut by them in the same proportions, like the lines drawn through three harmonicals in the porism already given of the harmonical curve. To this Newton had not adverted, nor to the unfortunate circumstance that the case of comets is actually the case in which the problem thus becomes capable of an infinite number of solutions. The error was only discovered after 1739, when it was found that the comet of that year was thrown on the wrong side of the sun by the Newtonian method. This enormous discrepancy of the theory with observation, led to a full consideration of the subject, and to a discovery of the porismatic case. When the studies of a philosopher, and especially of a mathematician, have been described, his discoveries recorded, and his writings considered, his history has been written. His private life is generally un- varied, filled with speculative inquiry, amused by scien- tific reading, variegated only by philosophic conversa- tion, unless when its repose is broken by controversy, an incident scarcely possible in the story of mathe- maticians. Dr. Simson loved to amuse his leisure hours, and unbend his mind in the relaxation of so- ciety ; and from the simplicity of his manners and the * Principia, lib. iii. prop. xli. SIMSON. 511 kindliness of his disposition, as well as from his very universal information, he was ever a most welcome member of the circles which he frequented. He lived in his college chambers to the last, but received his friends occasionally at a neighbouring tavern, where a room was always kept at his disposal. He attended a club near the college, and in good weather its mem- bers dined every Saturday at Anderston, a suburb of Glasgow. In these meetings his chair was always reserved for him, being left vacant when he happened to be absent. It is also said to have been his habit to sit covered. He was fond of playing for an hour or two in the evening at whist, and of calculating chances, at which he generally failed ; but he was on the whole a good player, though he was not very patient of his partner's blunders, nor always bore a bad hand of such partner with philosophic meekness. He was fond of music, and sometimes would sing a Greek ode to a modern air. Professor Robison says he twice heard him sing in this manner " a Latin hymn to the Divine Geometer," and adds, that the tears stood in his eyes as he gave it with devotional rapture. His voice was fine, says the Professor, and his ear most accurate. That he did not always interrupt his geometrical meditations in the hours of relaxation is very plain, not only from the singular anecdote already related of his discovery of porisms, but from the date of " Ander- ston " attached to some of his solutions, indicating that they had occurred to him while attending the Saturday meetings of the club in that suburb. In all his habits he was punctual and regular, even measuring the exercise which he took by the number of paces he 512 SIMSON. walked. Anecdotes are related of him when inter- rupted by some one on his accustomed walk, and after hearing what was said, continuing at the number he had just before marked, and surprising his acquaint- ance by speaking the next number aloud. He was exceedingly absent ; and the younger part of the uni- versity pupils were wont to play upon this peculiarity. It is related that one of the college porters being dressed up for the purpose, came to ask charity, and in answer to the Professor's questions, gave an account of himself closely resembling his own history. When he found so great a resemblance, adds the story, he cried out, " What's your name ?" and on the answer being given, " Robert Simson," he exclaimed with great animation, " Why, it must be myself!" — when he awoke from his trance. Notwithstanding his absent habits, he was an exceedingly good man of business ; he filled the office of Clerk of the Faculty in the University for thirty years, and managed its financial and other concerns with great regularity and success. Like all minds of a higher order, his not only had no contempt for details, but a love of them; and while clerk he made a transcript with his own hand of the University records, for which he received a vote of thanks from the Senatus Academicus. In 1758, being turned of threescore and ten, he found it necessary to employ an assistant ; when one of his favourite pupils, Dr. Williamson, was appointed his helper and successor. The University passed a resolu- tion stating his merits fully, recording in detail his services to the college and to science at large, and pro- nouncing a warm but just panegyric upon him. He SIMSON. 513 continued for ten years in the pursuit of his favourite studies, and the enjoyment of the same social intercourse as before. His health, which through his long life had been unbroken, remained entire till within a few weeks of its close, and he died on the 1 st of October, 1 768, having almost completed his eighty-first year. He is represented to have been of a calm and pleas- ing presence, of a portly figure, of easy and not un- graceful manners. A portrait of him in the college library remains, and is said to do him justice. His pupil, Dr. Moore, the Greek professor, and author of the cele- brated Grammar, also an excellent mathematician and great admirer of the ancient geometry, wrote the in- scription which appears under it, marking its author's own taste in more ways than one : — " Geometriam sub tyranno barbaro, saeva servitute, diu lan- guentem, vindicavit unus." His character was lofty and pure : nothing could ex- ceed his love of justice, and dislike of anything sordid or low ; nor could he ever bear to hear men reviling one another, and, least of all, speaking evil of the absent or the dead. In this he closely resembled his celebrated pupil Mr. Watt. His religious as well as moral feel- ings were strong, and they were habitual. No one in his presence ever ventured on the least irreverent or inde- corous allusion ; and we find the periods of his geome- trical discoveries mentioned with the date and the place, and generally an addition of " Deo" or " Christo laus," an example of which we have above presented. He never was married. Of his brothers, one, Thomas, was Professor of Medicine at St. Andrew's, and author of an ingenious and original work on the Brain ; his son succeeded him as professor. Another 2 L 514 SIMSON. brother was a dissenting minister at Coventry ; and a third, also settled there, had a son, Robert, first in the army, afterwards in the English Church — -Mr. Pitt, probably from his love of the mathematics, having presented him to a living in the north of Eng- land. He was Dr. Simson's heir-at-law, and to him the estates were left. He sold them in 1789, as well Kirton Hill as Knock Ewart, which had been pur- chased by the Professor's father in 1713. A niece of Dr. Simson was married to Dr. Moore, the well-known novelist, and was mother of the General. That illustrious warrior was therefore great nephew of the mathematician. Mrs. Moore survived to a recent period, and died in extreme old age. He bequeathed his mathematical library and manu- scripts to the University of Glasgow, with special direc- tions touching their disposition, custody, and use. They form, it is believed, the most complete collection of books and papers in that department of science any- where to be seen. The extraordinary genius of Dr. Simson for mathe- matical pursuits has been fully described in recording his achievements in that difficult branch of science. That he greatly furthered the progress of mathematical knowledge by his excellent publications of the ele- mentary works of Euclid and Apollonius cannot be denied ; nor can it be doubted that to him AVC owe a revival of the taste for the ancient analysis, the pure geometry, and the means now afforded of gratifying it. At the same time there is some room for lamenting that his great powers of mind and his patient industry of research were not devoted to the pursuit of more useful objects ; and there is good reason to agree in the SIMSON. 515 opinion expressed by one of his most eminent pupils, Professor Robison, that he might have better suc- ceeded in his favourite object of recovering the purely geometrical methods of investigation, had he relaxed a little more from their rigour in applying them to the present state of science, and shown the ancient analy- tical investigation dismembered of its prolixity, relieved from its extreme scrupulousness, and subservient to the investigations of the problems now become the main sub- jects of mathematical inquiry. This has in a great measure been performed by the most celebrated of his school, Matthew Stewart, who actually has solved Kepler's problem, and treated almost the whole doc- trine of central forces by means of the ancient method.* At the same time we have only to cast our eye upon his diagrams to be convinced that though he has solved the problems and demonstrated the theorems with a most wonderful skill, by means purely geometrical, yet he never could have obtained either the solutions or the demonstrations had not Newton preceded him, " his own analysis carrying the torch before."f The most celebrated proposition in all the ' Principia,' the general solution of the inverse problem of central forces J, (lib. i. prop, xli.) is closely followed by Stewart, and the diagrams are nearly the same. * His paper on the sun's distance, in which he also employs the ancient analysis, has been long since proved erroneous by my friend Mr. Dawson of Sedbergh, who wrote anonymously a demonstration of the error in 1772. •f " Sua mathesi facem praeferente." — H ALLEY. J I am aware of Professor Robison's statement, already cited, of Dr. Simson's opinion that the thirty-ninth proposition is the greatest of all, but I cannot help suspecting the forty-first to be intended. 516 SIMSON. This, however, is not the only ground of regret ; for had it been so, the teacher's defect has been thus supplied by the scholar. But good cause remains to lament that both of those great masters did not abate somewhat of their devotion to the Greek Geometry, and instead of being captivated only with the view of its incomparable beauty, did not help forward by their discoveries those branches of the science which, though they may have far less grace, have yet a far wider range and far greater usefulness. Surely it is deeply to be lamented that such extraordinary powers of original investigation as both these great men possessed should, especially in the case of Stewart, have been wasted upon what Professor Robison's learned wit terms " a super- stitious paleeology," and in the overcoming of difficulties raised by themselves — of reaching the point in view by a devious and hard ascent, when a short and an easy path lay open before them — of doing, and not very well doing, by an imperfect though elegant tool, and with no help from machinery, the same work which might with far better success and greater facility have been performed by the most perfect instrument that ever man invented ; like the laborious, patient, and ignorant Hindu, who with a knife will carve the most beautiful ivory trinket, on which he spends a lifetime that might have been employed in the most important works by the aid of fit implements — nay, who might have turned by a simple lathe myriads of the same kind of toy, THE END.

" A search has Jbeen made in the offices of the Secretaries of State and in the State Paper Office for the correspondence of Mr. David Hume when Under-Secretary of State with Marshal Conway ; but although letters have been found addressed to Mr. Hume in 1767-8, no letter signed by Mr. Hume can be found in any of the entry books of the period during which Mr. Hume was Under- secretary of State ; nor can any such letter be found in the books of the same period in the State Paper Office. " It would appear from the postscript of a letter from Mr. Carroll, dated at Dresden, April 13, 1768, that Mr. Hume's retirement had then been spoken of. " There are some letters in the State Paper Office in Mr. Hume's handwriting while Secretary to the Earl of Hertford, at Paris in 1763 ; and also his own letters when left as Charge d' Affaires in France, from the 28th of July to the 13th of November, 1765.
