which may be used as a direct or an indirect system, and is controlled automatically by the most improved form of temperature regulators. Ducts and channels have been pro- vided between the walls and in the iioor, so that pipes or wires may be laid from one part of the building to another without difficulty. The space in the building has been utilized as follows: Rooms for special purposes, small laboratories for work of investigation, large laboratories for general instruction, lecture rooms, class rooms, library and offices.

2 , FOSTER HALL equipment fund 575000, thus increasing that subscription to S225,000 and providing for the erection and equipment of the Ryerson Physical Laboratory. This laboratory was formerly dedicated on July 2, 1894. The building is a memorial of Mr. Martin Ryerson, who was a long and honored citizen of Chicago, and the father of Mr. Ryerson, the President of the Board of Trustees. In the design and construction of this building no element of utility has been omitted and every effort was made to include all the ' desirable features of a iirst class physical laboratory. All the walls and floors are strong and heavy: the laboratories on the lirst floor are provided with piers of masonry in addition to the heavy slate wall-shelves which are found throughout the building. Every laboratory is provided with gas for light or fuel, electricity for light and power, water. compressed air. and vacuum pipes. The laboratories are also equipped with a systt-in of lit-ating apparatus Nmsmsrm

devoted to the Work in electricity and magnetism. On the second floor are found a large general laboratory for ad- vanced undergraduate Work, optical laboratories, a chemical laboratory, large dark room, two developing rooms, and the large lecture hall with its adjoining apparatus and preparation rooms. The offices of the Director and Faculty are also on this floor. The third Hoor is devoted to a general laboratory for the under- graduate work in general physics, which, with its adjoining apparatus and preparation rooms, occupies the entire third floor of the east wing. MRS. BEE!!-IER On the same iloor are found two general laboratories and the rooms designed as the class rooms, library and reading rooms, but which are temporarily used by other departments. NIH XI-Rkl The central part of the fourth floor forms a hall for experiments requiring a large space. The roof above this portion is flat and suit- able for observations in the open air. A shaft has also been provided for pressure-gauges and for experi- ments requiring a greater vertical distance than is found in the labora- tories. Recent investigations have shown that the location of the Ryerson Laboratory is an exceedingly good one and that the outside disturb- ances which are usually so annoying are at a minimum.
