NATURAL SCIENCE GKOUP 111 the body (cardiac, respiratory, muscular, etc.), and measurements 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-twothousandth of a second. A moist chamber (made by the Cambridge Scientific Instrument Co.), with platinum and non-polarizable electrodes, is used in the study of the properties of muscle. Other instruments are a Fleischl spectropolarimeter, a Gower's hasmacytometer, a Gower's hajmaglobinometer, 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 a Sartorius balance, flasks and pipettes, thermometers, hydrometers, picnometers, etc. For illustrative purposes in anatomy and histology the department has an Auzoux 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 eleven courses: Three terms of major work, variously combined to form three courses, primarily for studonts in the school of natural science; a term of embryology for those who have taken one of the preceding courses; five courses in entomology; a year's work in comparative anatomy, zoological cecology, or advanced zoology for students specializing in that subject, and a year's work in independent investigation (senior) for those who select a zoological subject
