PHYSICS Professors: E. P. LEWIS, F. SLATE, Emeritus; E. E. HALL, R. S. MINOR, W. J. RAYMOND, L. T. JONES. Instructors: R. B. ABBOTT, R. T. BIRGE, W. H. WILLIAMS, E. DERSHEM, W. C. POMEROY. Facilities.-South Hall, which is devoted to the use of the department of physics, is a substantial brick building, with three stories and a basement. A small annex is occupied by a workshop and store-rooms. The greater part of the building is devoted to lecture rooms and laboratories for undergraduate instruction, but some small rooms in the basement and on the third floor are reserved for research purposes. The department is well equipped with apparatus for research in the fields of optics, spectroscopy, electricity, including discharge through gases, high frequency currents, and electric waves, and radiation and heat measure ments. Three competent mechanicians are employed in the shop, which is well equipped for the construction of apparatus after original designs for research purposes. Library. About 1600 volumes of standard works and special treatises on physics, exclusive of periodicals, are contained in the University Library. Duplicates of many of the books most in use are to be found in the department library, located in South Hall. All periodicals of interest to students of physics are to be found in the University Library, the sets being complete in nearly all cases. Duplicate copies of some of the most valuable journals are kept in the department library. Complete sets of the transactions and proceedings of the leading scientific academies and societies of the world are filed in the University Library. Fellowships and Assistantships.-The income of the Whiting bequest, amounting to about $1500 per annum, is available for research and fellowships. Usually two fellows are appointed each year. A number of assistantships are likewise open to graduate students. Publications.-The research activities of the department are indicated by the following list of publications during the past two years. In cases where the work is that of a student, this fact is indicated by his name, followed by that of the instructor directing his work. The coronal and flash spectra (Lewis); the polorization of the corona (Lewis); variations of the photoelectric current due to heating and the occlusion and emission of gases (Welo-Lewis); law of motion of a droplet moving with variable velocity in air (Abbott-Lewis); reflectivity in extreme ultra-violet (Hardy-Lewis); study of harmonic motion affected by resistance proportional to the square of speed (Van Zandt-Raymond); a synthesizer for the combination of damped harmonic curves (Raymond); the variation of the magnetic declination at Berkeley during the solar eclipse of June 8, 1918 (Raymond); the mercury-are pump; the dependence of its rate of exhaustion on current (Jones with Russell); laboratory uses of thermos bottles (Abbott); the value of the Rydberg constant (Birge); the dispersion of air and the reduction of wave-lengths to vacuum (Birge); the mathematical structure of band series (II) (Birge); the most probable value of the Planck constant "h" (Birge). Completed, but not yet published: the spectra of gases moving through a discharge tube (Baer-Lewis); the variations in the persistence of vision for different portions of the retina and for different colors (Hardy-Hall); the transmission of optical glasses for ultra-violet light (Minor); character of sound waves emitted from a moving source (Cook-Abbott). Researches in Progress.-The effect of temperature upon atmospheric ionization (Kunsman-Lewis); spectra in extreme ultra-violet (AsterLewis); the spectra of low potential discharges (Lewis); electrical and thermal conductivity at the fusion point (Greves-Hall); fused salts as electrolytes in primary batteries (Taylor-Hall); vibrations in buildings (Hall); a mechanism for illustrating the characteristics of alternating currents (Raymond); the velocity of sound as a function of the velocity of the source (Jones); resistance of batteries (Abbott); vacuum tubes for radio service (Abbott); velocity of sound waves emitted from a moving source (Stockton-Abbott); use of the method of least squares in laboratory work (Birge); X-ray spectra and the structure of the atom (Birge); the use of a photoelectric cell as a photometer (Cummings-Dershem); the spectra of X-rays (Dersham). Preliminary Requirements.—Students are admitted to graduate standing in physics by satisfying the usual requirements as to undergraduate major courses. No additional conditions have been formulated by this department, such questions as arise in these matters being settled individually. It can be said, however, that preparation for graduate work will include normally: (1) an elementary course amounting to 12 units, and embracing lecture, recitations and laboratory work; (2) a 6-unit course in analytic mechanics; and (3) other major courses selected by the student, in which an adequate proportion of laboratory work should be included. Working knowledge in the differential and integral calculus is needed, if free choice among major courses is to be exercised, and early acquirement of power to read French and German is almost indispensable. Plans for graduate study are usually arranged in conference with the individual students, because the necessary preparation in physics, or in special branches of it, and in mathematics, depends so largely upon the topic chosen. Therefore persons proposing to undertake work in special lines should consult as soon as practicable with the instructors who are most nearly concerned. Higher Degrees and Teachers' Recommendations.-The department has no special requirements, but all candidates should submit their plans for approval to the chairman of the department. 104A-104B. Physical Laws in Terms of Vector Analysis. WILLIAMS. PHYSIOLOGY Professors: R. GESELL, S. S. MAXWELL, T. C. BURNETT. Facilities.—About one-half of the Rudolph Spreckels Physiology Laboratory is devoted to research and instruction in physiology. The equipment permits investigation in the various fields of animal physiology. In the same building convenient to the laboratories is an excellent joint library of the departments of physiology and biochemistry. In addition to the six professors and instructors there are three assistantships which are open from time to time to graduate students of promise. Such positions offer adequate time for serious investigation. Fellowships in the form of internship in the fifth year of medicine, with salary, are open to medical students for the period of one year. These positions virtually give free time for research for the entire year. They are open to the medical student in either his third or fifth year. Research. Every effort is being made to encourage investigation by additions to the research equipment and by securing a large amount of free time for research for the members of the staff. This arrangement permits an intimate contact between the staff and the graduates actively engaged in research. Various problems are at present under investigation: factors controlling the volume-flow of blood; the dependence of submaxillary secretion upon the volume-flow of blood; electrical deflection of the sub-maxillary gland; effects of back pressure in the salivary duct upon subsequent secretion; the physiology of the labyrinth; the nature of the action of catalase; oesophageal reactions of the planarian; heat regulation; the effects of pituitary feeding upon the growth of rats with deficient thyroid. Preliminary Requirements for Higher Degrees.-Pending a rearrangement of the courses of the department no definite statement can be made. Students with the general scientific training necessary for the study of physiology who have completed an advanced laboratory course meeting the satisfaction of the department are eligible to the candidacy for higher degrees. 212A-212B.

Reed, *E. ELLIOTT, E. DAWSON. Lecturers: E. M. SAIT, C. E. MARTIN. Instructor: J. R. DOUGLAS. Facilities. The University Library is equipped for the study of the government and polities of the United States, of Spanish America, of the United Kingdom, France, and Italy. Its collections are being constantly added to, and together with the law library in Boalt Hall, offers opportunities for very thorough research into the government and the public law particularly of the English-speaking countries, and of France and Italy. Materials for the study of the Far East and the Pacific, as well as eastern Europe and Germany, are constantly being increased. The Bancroft Library contains extensive materials for the study of the institutions and politics of Spanish America. The Bureau of Public Administration and the Bureau of International Relations, both forming part of the department and conveniently situated in the Library, provide opportunities for reference and research together with expert assistance and guidance by their secretaries, to the students who wish to make use of these bureaus either for casual reference or for systematic research. The collections of materials contained in the bureaus are constantly being extended. The scope of instruction in this department includes the government of modern American and European states, their administration, internal politics, and history of political institutions; the government of American dependencies; state government and administration in the United States; local and municipal government in the United States and in Europe; comparative public law; political theories and their history; international relations and diplomacy; the teaching of civics in high schools. Research. Higher degrees granted in the last few years were based on theses dealing with municipal government, government of the Philippines, foreign relations of China and Japan and world organization. Research work now being pursued by graduate students covers the fields of state administration, international relations, theory and practice of martial law, legal organization of the care for child welfare, history of political theories in the United States. * Absent on leave, 1919-20. |
