The French have been celebrating with enormous enthusiasm the hundredth
anniversary of the birth of one of their con- siderable chemists, M. Chevrenl, who was born at Angers on August 31st, 1786, and is still in excellent health and full of energy. He entered early Vauquelin's laboratory in Paris, and in 1813,—the year of the retreat from Moscow,—was made Pro- fessor at the Lye& Charlemagne, and also at the Gobelins manufactory, where he directed the dyeing department. In 1830 he became Professor of Applied Chemistry in the Natural History Museum. He protested against the barbarism of the siege of Paris in 1870, by which he said the Jardin des Plantes had been injured. M. Chevreul, as we have elsewhere remarked, treated his hundred years of experience as a great lesson in optimism. His centenary is regarded as a great event in France, though why exactly it seems to be held so creditable to live to a hundred we do not clearly Bee.
