INTRODUCTORY

The courses of the Department of Physiology are arranged for three classes of students:

I. Junior or Senior College students who wish to acquire a knowledge of the structure and functions of the human body, or who wish to study biology from the physiological side. To satisfy the needs of these students and enable them to cover the subject satisfactorily, a two-major course is given: courses 1 and 2, Introductory Physiology. In order to make it accessible to a large number of students no prerequisites are demanded.1

II. Medical students. The work is covered by courses 12, 13, 14, 19, 20, and 21. As Physiology has to apply Physics and Chemistry to the explanation of life-phenomena, a good knowledge of Physics and Chemistry is essential for the work of these courses. The same courses, or certain of them, will be found useful to students who intend to specialize in Zoology, Botany, or Psychology.

III. Students wishing to specialize in Physiology, Physiological Chemistry, or Pharmacology. For such students an extensive knowledge of Physics and Chemistry is necessary. For each major or double-minor course requiring laboratory work, the laboratory fee is $2.50.

1 Students who wish to get the most possible out of the course are strongly urged to acquire some chemical knowledge before beginning the work. As the accommodations are limited, preference in registration will be given to those students who will arrange their work so as to be able to take both 1 and 2.

INTRODUCTORY

While the Department keeps in view the usefulness of Botany in contributing to a liberal education, its method is the same in aiding general culture as in training investigators. Beginning with the fundamentals of Biology from the standpoint of Botany, the courses gradually differentiate into more and more special lines until finally they become adapted to the needs of the individual investigator. The method of the Department is the careful, individual examination of the facts upon which the body of the science rests. The Department occupies the Hull Botanical Laboratory. At present there is provision of apparatus books, periodicals, and collections, for work in Morphology, Cytology, Physiology, Ecology, and Taxonomy. In addition to the facilities belonging to the University, the herbarium of the Field Museum of Natural History and the conveniently situated grounds and greenhouses of Jackson and Washington Parks are always available for material.
