But, by a furious act of violence, he was condemned to die. He asked only a few days to complete some experiments which were going on during his imprisonment. The scoffing answer of this merciless tribunal was, that the Republic had no need of philosophers; and on the day after this sentence, the 8th of May 1794, he was hurried to the guillotine with no less than one hundred and twenty-three other victims, who all died within a few hours.
On this melancholy and desperate atrocity of republicanism, Lord Brougham makes the following remark, which, though natural in the lips of any human being, has double force as coming from one who has seen the operation of the revolutionary spirit on so large a scale, and during so extended a portion of his public career.
"The lustre," he observes, "which the labours of Lavoisier had shed over the scientific renown of France, the valuable services which he had rendered her in so many important departments of her affairs, the virtues which adorned his character and made his philosophy beloved as well as revered, were all destined to meet the reward with which the tyranny of _vulgar faction_ is sure to recompense the good and the wise, as often as the _base unlettered multitude_ are permitted to bear sway, and to place in the seat of dominion their idols, who _dupe_ to _betray_, and finally punish them."
Lord Brougham justly reprobates the suspicious silence of the celebrated Carnot on this occasion, and the still more scandalous apathy of Fourcroix, who had been the pupil and panegyrist of the great chemist during many years. He acquits him of the deadly imputation, that he had even been instrumental in sending his master to the guillotine. But he praises, in contradistinction, M. Hallé, who had the honest courage to proclaim Lavoisier's public services before the dreadful tribunal, while he consigns the pupil to perpetual scorn. He was murdered in his fifty-first year.
Lord Brougham's French predilections do credit to his sense of cosmopolitism; but he appears to us somewhat more disposed to conciliate the jealousy of his very irritable French _confrères_, than to deal rigorous justice. No man deserves the reputation of science but a discoverer. To know all that has been hitherto known on a subject, deserves the character of diligence; to promote the progress of a science by largeness of expenditure, or steadiness of exertion, deserves the praise of liberality and labour; but the man who adds to the science by original invention, who enlarges its boundaries, and detects new principles, is the man alone to whom the name of genius can be applied. Lavoisier was, unquestionably, an important minister of science; he possessed singular assiduity, unwearied zeal, and remarkable sagacity. What these could do, he did; what knowledge could accomplish, he performed; but the inventors were of another country, and of a higher order, and he must be content with the honours due to imitation. Yet he had considerable happiness in the difficult art of communicating his knowledge. His _Treatise on Chemistry_, though now superseded by subsequent arrangements, is singularly clear; and no great teacher of chemistry has hitherto given the world a more striking example of exactness in detail, and clearness in conception.
