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 His _Treatise on Chemistry_, though now superseded by subsequent arrangements, is singularly clear; and no great teacher of chemistry has hitherto given the world a more striking example of exactness in detail,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. His cruel death, too, may be almost said to have continued his services to society. It proved, with irresistible force, the true character of Infidel Revolution. It showed a noble-minded and benevolent man the victim of revolutionary rage; an intelligent, studious, and retired man, obnoxious to the rabble love of ruin; a mild, generous, and patriotic man, the instant prey of revolutionary government, which boasted of its superiority to the vices of kings, of its homage to intellect, and of its supreme value for the virtues of private life. Yet it murdered Lavoisier without a moment's hesitation, or a moment's remorse, and flung the first philosopher of France into a felon's grave. The biography of Adam Smith gives Lord Brougham an opportunity of pouring out, at the distance of nearly half a century, that knowledge of Political Economy which first brought him into notice. His _Colonial Policy_, a remarkable performance for a student of eighteen, exhibited in miniature the principles and propensities which his long career has been expended in maturing and moulding. Adam Smith was the idol of all Scottish worship in the last century; and his originality of conception, the weight of his subject, and the clearness of his judgment, made him worthy of the elevation. Adam Smith's birth was of a higher order than is often to be found in the instance of men destined to literary eminence. He was the son of a comptroller of the customs, who had been private secretary to Lord Loudoun, secretary of state, and keeper of the great seal.
