In prosecuting, the experiments, detailed in the treatise which he has published on the apple and pear, this eminent physiologist seems to have kept constantly in view, the analogy between the animal and vegetable kingdoms.

"The effects of cultivation," says he, "on the animal and vegetable systems, are extremely similar. A change in form, in colour, in size, or stature, takes place in each; and in each these changes appear to arise from similar
