By their nature the proceedings of any conference are highly vulnerable reports, readily subject to extensive criticism. This publication is no exception. One cannot help but admire, however, the efforts of workers to relate endocrinology and behavior. As a science, endocrinology remains operationally very diffuse with many almost independent subunits or specialized interests. Despite the years of study, behavioral inquiries defy even the simplest summary statements that meet with universal acceptance.

Historically, the various endocrine glands have served as subject material for largely independent and unrelated subspeciality studies. Perhaps the most commendable contributions at this conference were the rather lucid reviews of the current state of information concerning the functional ``geography'' of the hypothalamus in effecting the integrated responses of a number of the endocrine
