EFFECTS OF GRAFTING AND FEEDING WITH PITUITARY Many attempts have been made to increase the internal secretion of thepituitary—especially of the pars anterior—by grafting the organ or portionsof the organ from an animal of the same species into various parts of thebody; but these have always so far resulted in failure, the graft disappear-ing, or at any rate undergoing degeneration, in the course of a few white rats, rabbits, and guinea-pigs I have repeatedly implanted theorgan as a whole or in small pieces under the skin of
