COURSES IN OTHER DEPARTMENTS Spectroscopy. [See Physics 211.]. Railroad Surveying. [See Civil Engineering 102.] Higher Surveying and Geodesy. [See Civil Engineering 105.] LEWIS FOOTE FOOTE LICK OBSERVATORY The Lick Observatory at Mount Hamilton forms a separate department of the University. The unrivaled facilities for advanced astronomical work which are offered by its fine equipment, in this favorable location, are too well known to require description here. The department is open to graduate students under regulations prescribed by the Regents. The degrees of Master of Arts and Doctor of Philosophy are offered to students who have fulfilled the required conditions. (See Announcement of the Graduate Division.) For information relating to graduate work at the Observatory intending students should address the Recorder of the Faculties at Berkeley, or the Director of the Lick Observatory, at Mount Hamilton, Santa Clara County, California. BIOCHEMISTRY AND PHARMACOLOGY WALTER R. BLOOR, Ph.D., Professor of Biochemistry. CARL L. A. SCHMIDT, Ph.D., Assistant Professor of Biochemistry. GUY W. CLARK, Ph.D., Instructor in Pharmacology. G. LEB. FOSTER, M.A., Associate in Biochemistry. Assistant. PREPARATION FOR THE MAJOR Required: matriculation physics and chemistry; Chemistry 1 (10 units), 8 (3), 9 (3). For medical students, in addition to above, Zoology 1 (9). Recommended: Chemistry 5; German, Zoology 1, or Physiology. For science and general students the prerequisites for the study of biochemistry are as follows: Matriculation physics and chemistry, Chemistry 1A-1B, 8 and 9. A course in biology, e.g., Zoology 1A-1B or Physiology, is desirable. For medical students the prerequisites are as prescribed for the medical school. Courses 101 and 102м are required. The attention of intending advanced students in biochemistry is called to the fact that modern developments in this field call increasingly for a good knowledge of physical chemistry, quantitative chemical methods and the ability to read French and German scientific literature. The equipment of the department affords ample opportunities for research. Facilities are offered to any qualified student who desires to undertake a well planned investigation in the field of biochemistry. The joint library of the departments of biochemistry and physiology contains complete sets of the more important biochemical, physiological and pharmacological journals and the more important books and monographs on biochemical and related subjects. The division of Clinical Laboratories (U. C. Hospitals) is now included in the department of Biochemistry and Pharmacology, but no courses are given. UPPER DIVISION COURSES 101. Biochemistry. (9) II.
