CHEMICAL EQUIPMENT. The department occupies the spacious McMillan Chemical Laboratory, with ample space for its lecture rooms and laboratories, and every convenience is provided for both the instructors and students pursuing general or special courses. The basement contains the Portland cement laboratory, the assaying room, the mineralogical collections and the furnace room. In the first story, which is 13 feet high, there is the organic laboratory, 27 by 30 feet, containing tables for 24 students, with 29 feet o f hoods, also wall tables, cases for chemicals, etc. Adjacent to this are the quantitative laboratory, 22 by 30 feet, tables for 20 students, hoods, wall tables, etc., a combustion room, 10 by 17 feet, and dispensing room, 10 by 21 feet. On the other side of the hall is the instructor ' s study. Off this is a private laboratory, with large table, hoods, wall tables, etc.

YEAR BOOK 1 with the Mime lighting arrangements at 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 purposes. The Biological Department is well supplied with such appara- tus as is needed for its work, including over sixty compound micro- scopes, dissecting 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 contribute to the work in Ecology. It already contains over fifteen hundred species in the herbarium nearly twelve hundred of which are representative of this locality, and many of them represented in numerous specimens which show the plant in immature and winter condition, as well as in flower, etc. There is also a large number of specimens of seeds, woods, barks, fibers, medicinal 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 instruc- tion, others are being added as occasion demands. The photo- graphic 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 oi the professor in charge is on the first floor, adjacent to the Zoological Laboratory, where he may be consulted at any time by those having need of his assistance. PHYSICAL EQUIPMENT. The laboratory work in the department of Physics has b«en greatly strengthened during the past few years by the acquisition of a considerable amount of modern physical apparatus.

YEAR BOOK 17 The balance room, 9 by 11 feet, and a research room, 15 by 30 feet, complete the equipment of this floor. The second story is also 13 feet high and contains the quali- tative laboratory, 40 by 49 feet, with tables for 80 students, with seven hoods, wall tables, cases, etc. The lecture room, also on this floor, 30 by 37 feet, will accommodate 82 students, the seating being arranged in rising tiers of chairs. The third story is 10 feet high and contains the laboratories of Physics and the Physics Lecture Room. There are eight separate working laboratories all fully supplied with apparatus and chemicals and equipped with gas, water, venti- lation hoods, desks and lockers for each student. These are located on the first and second floors and the basement. The chemical lecture room on the second floor has seating for 80 students and is thoroughly furnished with a large demonstrating lecture table containing pneumatic cistern, oxygen tanks, exhaust, gas, water, sinks, battery, with ventilating hood in rear. Each floor is provided with a capacious dispensing room where chemicals and apparatus are stored to be issued to the student as required. The General and Qualitative Chemical Laboratory on the second floor is equipped with 80 working tables, each having a sink, hood, water faucets, gas, reagent bottles. From the adjacent room may be obtained all chemical apparatus required by the students in their work. The advanced courses are conducted on the first floor and in the basement where are located laboratories for Quantitative, Or- ganic and Technical Chemistry. Every facility is afforded for thorough work. Attached to the laboratories on the second floor is a thoroughly equipped weighing room containing accurate balances, specific gravity apparatus, etc. Tn the basement is located the Laboratory for Portland Cement and assaying, providing all the necessary apparatus for the physical testing of cement and the assaying of ores. Here are crucible and muffle furnaces, both coal and gas, for the fire assays of ores and also crushing, pulverizing and sampling apparatus, tensile strength machines, specific gravity apparatus and all the regular equipment used in the practical handling of cements and ores. A complete laboratory for Gas Analysis, with special reference to its application in the manufacture of illuminating gas, has been installed.
