the Physiological Society and appointment by the council.

A noteworthy event of the meeting was an exhibit of old and historical books on anatomy and physiology arranged by Professor Arno B. Luckhardt, of the University of Chicago. This exhibit was open during the entire session. A very profitable scientific program was carried forward as recorded below. The society in closing its annual session passed the following resolution:

Resolved: That the American Physiological Society expresses its keen appreciation to the authorities of the University of Chicago and to the local committee for the numerous and effective arrangements that have contributed in a large degree to the scientific and social success of this the thirty-third annual session of the society.
