84 COLLEGE OF SCIENCE. ments are made of the rate of transmission of pulse waves, nerve currents, etc. With the assistance of a tuning fork, kept in vibration electrically, and a Deprez signal (made by Verdin), these measurements are accurate to within one two-thousandth of a second. A moist chamber (made by the Cambridge Scientific Instrument Co.), with platinum and nonpolarizable electrodes, is used in the study of the properties of muscle. Other instruments are a Pleischl spectropolarimeter, a Gower's haemacytometer, a Gower's hsemaglobinometer, a spectroscope, and a Lautenschlager oven, with automatic temperature regulator. The apparatus for the chemical side of the subject, although in the aggregate important and costly, is composed largely of small pieces, too numerous for individual mention. Among them may, however, be named a set of Hempel's apparatus for gas analysis, and a Knop azotometer, the last used mostly in urinary analysis. For the measurements of mass, volume, temperature, barometric pressure, specific gravity; etc., so constantly necessary in both the physical and chemical work, the laboratory is well supplied with apparatus of the best construction, including Sartorius balance, flasks and pipettes, thermometers, hydrometers, picnometers, etc. For illustrative purposes in anatomy and histology the department has an Auzonx manikin, a human skeleton, a series of charts, mostly histological, about a hundred and fifty histological slides, and a number of wet preparations of lower animals. Compound and simple microscopes, microtomes, and the usual accessories for histological work are also available. ZOOLOGY. Zoology is taught in nine courses: Three terms of major work, variously combined to form three courses, primarily for students in the school of natural science; a term of embryology for those who have taken one of the preceding courses; three courses in entomology amounting to two years' work; a year's work in comparative anatomy, zoological oecology, or systematic zoology (including palaeontology), for advanced students only; and a year's work in independent investigation (senior) for those who select a zoological subject for the graduating thesis. Only the first term's work is necessarily common to all students
