THE GRADUATE SCHOOLS

Dr. W. B. Cannon '96, George Higginson Professor of Physiology at the Harvard Medical School, will give a lecture tomorrow at 4 o'clock at the Medical School, Longwood Avenue, Boston.

Dr. Cannon will lecture on "Natural Defenses of the Body." This is the fourth of a series of free public lectures sponsored by the Harvard Medical School. No tickets are required.

Dr. Cannon has been conducting a series of investigations since 1896, concerned with the natural defenses of the body against bacteria, mechanical disturbances, and against thermal and chemical changes in environment. He has paid particular attention, in his research to the best regulation of the body, and the coagulation and sugar content of the blood.
