But the best of all the varieties is the white-fruited, which does not differ in the leaf from the first described, but the racemes are large, long and dense, the berries oval, white or green, with a slight coppery tinge on the side exposed to the sun.

In warm dilute hydrochloric acid it is slightly attacked, but not completely dissolved. Tested for nitrogen by Lassaigne's method, by fusion with sodium and obtaining the precipitate of prussian blue, it indicated the presence of considerable quantities of that element. As the body appears to be composed of at least three substances, and the quantity at my disposal...

Perhaps the accumulation of honey in the ant is the result of a disease like diabetes, though it would seem improbable that it should be a disease so widely diffused. The examination of compounds occurring in the lower animals, which are also the result of the decomposition of amylaceous and albuminous substances, and a comparison of these compounds with the animal's food, has been much neglected by chemists. Yet it would...

A careful examination of the relation between food and its transformation in the bodies of such animals would no doubt throw great light upon mooted points in physiology ; and the many differences in the nature of the products, which could no doubt be reconciled with the laws of chemistry, would in themselves afford one of the...

If it be desirable to study that mysterious force, the vital, how can it be done but by its effects, for which nature must be crossexamined in her every form? This is the more important, as we find vitality to determine the resolution of the same food into different products in different animals, as may be required for...
