EXTIRPATION OF THE PINEAL BODY.
1. Following the removal of the pineal I have observed no sexual precocity or indolence, no adiposity or emaciation, no somatic or mental precocity or retardation. 2. Our experiments seem to have yielded nothing to sustain the view that the pineal gland has an active endocrine function of importance either in the very young or adult dogs. 3. The pineal is apparently not essential to life and seems to have no influence upon the animal's well being.
