For several years previous to his death, De Cnudolle suffered from ill.health. In 1811 he was induced to visit the meeting of naturalists held nt Turin, in the hope that change of climate would restore his failing powers, but he derived no benefit from his journey, and died on the 9th of the following September.
As a botanist Do Candolle must be placed in the first rank in the century in which he lived. He possessed a quick apprehension, which enabled him to make use of the labours of others, added to a habit of methodical arrangement, by which he could at once refer the various facts that came to his knowledge to their proper position in the departments of the science which he pursued. It was this which, combined with a clear and pleasing delivery, made him a successful lecturer, and enabled him to produce with rapidity so many works on botany. But he was not only a botanist : he was earnest in hie sympathies with mankind, and was a zealous philanthropist and energetic oitizen. In Paris, in the early part of his life, under the auspices of Benjamin Dela:mit he took an active part in the formation of the Soci6t6 Philanthropique of Paris, and the Society for the Encouragement of National Industry was formed under his direction and management. He was for many years a member of the legislative of Geneva, and also rector of the academy in the same place.
