(3) For students planning to study medicine, courses 1A, 1B, 4, 103, 106, 107, 110, 110c, 111, 111c, 114, 115.

(4) For non-biological students, courses 10, 104, 114, 115 and 116. Students who plan to enter instruction or research in zoology as a profession should not only lay a broad foundation in the courses in zoology but should also include at least the fundamental courses in chemistry and physics in their course of study. Courses in bacteriology, botany, entomology, microscopic anatomy, palaeontology and physiology may be included to advantage, and a reading knowledge of French and German is essential. Research in biometrics requires a knowledge of higher mathematics (Mathematics 120) and statistical methods (Economics 140).

Honors-students in the Upper Division.-To honors-students whose major is zoology the department offers closer supervision of their work, larger facilities in material and equipment, and wider latitude in selection of subject-matter. Its purpose is to foster initiative and independent effort. Honors-students may select a member of the staff as adviser. Guidance in a selected course of reading will be afforded.

A major in zoology should include any two of the groups of courses listed under (1) above. The remainder of the 24 major units may include any upper division courses in zoology. Upper division courses in allied natural sciences will be accepted to the extent of 8 units when approved by the department.
