*25. Advanced Cryptogamic Botany.

Professor SETCHELL. The cryptogams of California offer exceptional opportunities for

research, and many simpler problems are presented for original investigation. This work during the year will be confined almost exclusively to the algæ, in connection with the special work of the instructor. Students should expect to devote considerable time to this course.

26. Advanced Phænogamic Botany. Assistant Professor JEPSON. Special problems requiring the original investigation of some

particular order or smaller group of flowering plants. This course involves work in the field as well as in the laboratory.

ZOOLOGY.

WILLIAM E. RITTER, Ph.D., Professor of Zoology.
John C. MERRIAM, Ph.D., Assistant Professor of Palæontology and

Historical Geology.
CHARLES A. KOFOID, Ph.D., Assistant Professor of Histology and

Embryology
HARRY B. TORREY, Ph.D., Instructor in Zoölogy.
CALVIN 0. ESTERLY, A.B., Assistant in Zoölogy.

The courses are planned to meet the needs of three classes of students, viz.:

(1) Those who wish, for the purposes of general culture, some knowledge of the subject-matter, methods and generalizations of biological science on its animal side. For this class Courses 1, 2, 3, 7A and 17 are particularly designed.

(2) Those preparing to become teachers and investigators. For such the individual aims of the student will determine, after the fundamental courses have been taken, what advanced courses he shall select. The minimum for the Teachers' Recommendation is 1 (first half), 2, 3, either 4 or 5, 7A and 17.

(3) Those preparing for the study of medicine. For these, Courses 1 (first half), 2, 3, 4, and 5 or 6 are requisite to fulfil the requirements of the Pre-Medical Course.

Laboratory deposit is seven dollars for each laboratory course. The amount returned at the end of the course will depend upon the actual cost of the material consumed, the character and amount of the apparatus used, and the breakage.

The Group Elective. At least a year of Chemistry in the University, or its equivalent, and Zoology 1, 2, 3, 7A and 17, are prerequisite to the Group Elective in this department.

1. The Fundamentals of Zoology.

Professor RITTER. The underlying principles of animal life and evolution. The treat

ment is topical rather than systematic. Illustrated lectures.
