relative value to the student of laboratory work as compared with experimental lectures, of qualitative and quantitative experiments; of the extent to which industrial applications and every-day reactions should be emphasized; of text-books, their uses and abuses; and other similar topics. The object of the course is the assistance of teachers and any problems confronting teachers of chemistry may be considered. 2 units.

NATHANIEL LYON GARDNER, Ph.D., Teacher of Botany, Polytechnic High School, Los Angeles.

1. Laboratory Course in General Science.

Associate Professor OSTERHOUT and Dr. GARDNER. A course suggesting ways to make familiar the general principles underlying every-day phenomena. It deals chiefly with questions arising out of the pupil's daily experience. The principles which these questions involve are experimentally studied by means of simplified apparatus such as pupils

can themselves make. Practical applications of these principles are explained and fully discussed. 2 units.

2. Biology and Agriculture.

Associate Professor OSTERHOUT and Dr. GARDNER. Biological principles, including a discussion of Mendelism, nutation and plant breeding; familiar phenomena of plant and animal life and their interpretation; means of study; experiments and methods for schools; applications in sanitation, hygiene, and especially in agriculture. 2 units.

The lectures may be taken separately. 1 unit.

Lectures M Tu, 9; M, 4. 2 Botany Building. Each lecture on Monday at 4 will be followed by an excursion to the botanical garden. Field work, 5 hours per week, to be arranged individually.

JOSEPH GRINNELL, M.A., Director of the California Museum of Vertebrate Zoology.

1. The Birds, Mammals, and Reptiles of California.

Mr. GRINNELL. A course designed to acquaint the student with our common terrestrial vertebrates, and thus of value to teachers of Zoology and nature-study. How to identify birds, mammals, and reptiles; their habits and life-histories; beneficial and injurious species; the songs of birds; migration; geographical distribution and variation as exhibited in the fauna of California; preservation of specimens, and the care and use of a school museum. Lectures, laboratory work, and field trips. 2 units.

2. Systematic Ornithology.

Mr. GRINNELL. An examination and application of the methods of classification, as illustrated by the research collection of 16,000 birds; the significance of geographic variation and isolation in the processes of evolution; feather-structure, molt and abrasion; methods of field work; preparation of study skins; recording of field observations; cataloguing of a collection. Lectures, laboratory and field work. 1 unit, or more, according to the time the student can devote to the subject.

The Marine Biological Survey that has been in progress for several years on the coast of Southern California by the Department of Zoology will be continued with broadened scope and increased facilities at the La Jolla station during the coming year.

While, as heretofore, the whole time and effort of the staff of the laboratory will have to be devoted to research, a limited number of students sufficiently advanced to be able to work under the guidance of the investigators to the advantage of both themselves and their directors will be gladly admitted.

The station will be open from June 1 to August 15. Applications for admission to its privileges for the whole or a part of the season should be sent as early as possible to Professor William E. Ritter, Berkeley, California.

Graduate students who are candidates for higher degrees in the University may, with the approval of the Professor of Zoology, count the time spent at work in the laboratory as university residence for such degrees.


SAMUEL STEEN MAXWELL, Ph.D., Assistant Professor of Physiology.

1. Physiology for Secondary Schools.

Assistant Professor MAXWELL.

Since physiology has been placed on the list of admission subjects for entrance to the University there has been a very

apparent confusion in the minds of applicants, and of teachers as well, in regard to the content and methods of a course that would meet this requirement.

The course offered in the Summer Session is planned primarily for teachers, who, although informed on the subject matter, desire a more scientific basis and a wider view. The matter and the methods deemed essential to secondary work in physiology, especially as regards laboratory work, will be reviewed. Some of the lectures may exceed the range of secondary school work, but will be of importance to those who wish to be well equipped for that grade of teaching. Laboratory work will be optional, but teachers will find this the preferable way to learn methods for use in their schools. The time in the laboratory will be given mainly to physiological experiments rather than to dissections or other anatomical work. Especial attention will be directed to the simplification of methods and apparatus. The fee for the laboratory work is $2.50. 2 units.

Students who complete the laboratory work satisfactorily and pass an examination at the end of the course can secure credit for Matriculation Subject 12f.

Lectures M Tu W Th F, 10; laboratory, 8-10. The Rudolph Spreckels Physiological Laboratory.

2. The Imitation and Control of Life Phenomena.

Assistant Professor MAXWELL. The object of this course will be to present in as simple and non-technical language as possible some of the results of experimental biology and general physiology. In no way has the understanding of life phenomena been so remarkably advanced as by those investigations which have shown how life processes can be artificially imitated and controlled. Among the topics discussed will be protoplasmic movement and its artificial imitation, the direction and control of animal movements through the action of physical agents such as light, gravitation, galvanic currents, etc. (the tropic reactions of animals), chemical fertilization and artificial hybridization. 2 units.

1. School Hygiene.

Dr. HOAG. A course of lectures and recitations on that part of the subject of Hygiene which applies directly to conditions in schools. Some of the lectures will be illustrated with lantern slides showing actual school conditions. The course is designed to interest parents as well as teachers. The topics covered will include general relations of health to education; physical conditions found among school children; sanitation of grounds and buildings; history of medical work in schools in Europe and America; how to detect physical defects in school children; record systems; the school physician and the school nurse; physical education in relation to health; the pupil and the home; health of teachers; contagious diseases and their control; the nutrition of school children. 2 units.

3. The Elements of Bacteriology.


Designed to give a general knowledge of bacteriology, as well as an equipment in the teaching of biology in the public schools. The course will include laboratory work in methods of study of bacteria, methods of milk and water examination, of disinfection and sterilization, a study in the laboratory of the household importance of bacteria, and of the causative organisms in a few of the commoner infectious diseases. 2 units.
