The devotion to science which Buffon had thus manifested marked him out for an appointment which determined the course of his future life. His friend, Du Fay, who was the Intendant of the ‘_Jardin du Roi_’ (now called the ‘_Jardin des Plantes_’), on his death-bed recommended Buffon as the person best calculated to give a right direction to this establishment for the cultivation of natural history. Buffon seized upon the opportunities which this appointment afforded him of prosecuting his favourite studies, with that energetic perseverance for which he was remarkable. He saw that natural history had to be written in a manner that might render it the most attractive species of knowledge; and that philosophical views, and eloquent descriptions, might supersede the dry nomenclatures, and the loose, contradictory, and too-often fabulous narratives which resulted from the crude labours of ill-informed compilers. To carry forward his favourite object, it was necessary that the museum, over which he had now the control, should be put in order and rendered more complete. He obtained from the government considerable funds for the erection of proper buildings; and the galleries of the ‘_Jardin des Plantes_,’ which now hold the fine collection of mammals and birds, were raised under his superintendence. Possessing, therefore, the most complete means which Europe afforded, he applied himself to the great task of describing the animal, vegetable, and mineral kingdoms of nature. A large portion of this immense undertaking was left unperformed, although, to use his own words, he laboured fifty years at his desk; and much of what he accomplished was greatly diminished in value by his determination to see natural objects only through the clouded medium of his own theories. But, nevertheless, he has produced a work which, with all its faults, is an extraordinary monument of genius and industry, and which will long entitle him to the gratitude of mankind. “We read Buffon,” says Condorcet, “to be interested as well as instructed. He will continue to excite a useful enthusiasm for the natural sciences; and the world will long be indebted to him for the pleasures with which a young mind for the first time looks into nature and the consolations with which a soul weary of the storms of life reposes upon the sight of the immensity of beings peaceably submitted to necessary and eternal laws.”
