16 ALBION COLLEGE specimens which show the plant in immature and winter condition, as well as in flower, etc. There is also a large number specimens of seeds, woods, barks, fibers, medici- nal and commercial products. It is designed to make this collection as completely representative of local plant life and plant products as possible. The Zoological Lecture Room is so arranged as to be speedily darkened and is provided with a stereopticon; and while there is an ample supply of lantern slides on hand for purposes of instruction, others are being con- tinually added as occasion demands. The photographic equipment of the laboratory is such as to highly facilitate the rapid increase of this collection. All the laboratories have individual private lockers, each with its own combination lock, and water and gas connections are liberally provided throughout. The supply of material for study and dissection is large and is ample in amount and range of species for both elementary and advanced study. It is constantly enriched through purchase as well as by the collections made by the department and friends of the College. The study and private laboratory of the professor in charge is on the first floor, adjacent to the Zoological Laboratory, where he may be constantly consulted by those having need of his assistance. The department acknowledges, gratefully, the gift from Mr. E. E. Sherff, class of 1907, of collections of plants illustrating desert conditions. PROVISIONS FOR THE STUDY OF PHYSICS. The laboratory work in the department of Physics has been greatly strengthened during the past few years by the acquisition of a considerable amount of modern phy- sical apparatus. Among the instruments now available for class illustration and laboratory work are the follow- ing: Vernier calipers, micrometer gauges, microscopes, telescopes, spherometers, Jolly ' s balance, Hawkes-At- wood ' s machine, Toepler-Voss self-charging electrical ma-

YEAR BOOK 15 illumination, and eye pieces giving range from a low- power comet-seeker to eight hundred diameters. The Transit Circle, by Fauth Co., is of a four-inch aperture and is provided with micrometers in right ascension and declination, levels sensitive to one second of arc and verti- cle circles reading to single seconds by micrometer micro- scopes. The Sidereal Clock and Chronograph are by the same makers. , All of the instruments are in electrical connection. PROVISIONS FOR THE STUDY OF BIOLOGY. The Biological Department occupies the new Biologi- cal Laboratory, erected as an addition to Robinson Hall. This addition is 45 by 60 feet, three stories high, above the basement. It contains large laboratories for the classes in Zoology and Botany, accommodating respective- ly 60 and 40 students. Besides the large windows at the end of each table there are electric lights and gas arc lights that afford ample illumination for evenings or dark days. There are commodious lecture rooms adjoining each. Besides these laboratories there are smaller labo- ratories for more advanced classes, with the same lighting arrangements as in the larger laboratories, as described above. Store rooms and supply rooms, with a large room for a working Botanical Museum occupy the remainder of the space on the lower three floors. On the upper floor are rooms for Museum workshops, with a suite of three rooms which are fully equipped for photographic pur- poses. The Biological Department is well supplied with such apparatus as is needed for its work, including over sixty compound microscopes, rocking, sliding and rotary micro- tomes, incubator, aquaria, embedding apparatus and a collection of several thousand mounted slides. The Botanical Working Museum is especially designed to con- tribute to the work in Ecology. It already contains over one thousand species in the herbarium, nearly all from this locality, and many of them represented in numerous
