The facilities for Instruction in physlcs at the University of Michigan have long been inferior to those of other departments. 'i'liis deliclency was brought to the attention of the last state legislature, mul apDroprlatioDswere made, both for a large addhion to the apparatus and for a new building for a physical laboratory, now in procesa of construction. The plans of the building and the purposes of the departmeiHare of interest to electricians, beeause of the large provisión made for instructioii in eleclricity on a commercial scale. The basement and first floor plans will indícate clearly the general arrangement of rooms lvoted to physies. The second story will accomuiodate the new departnutnt of hygiëne. Tlie greatest dimunsiona of the building are 72 feet by 115 feet. The main eutrance is on the north side, and a descent of five steps leads to the basement iloor, which isonly two feet below grade. The basement rooms are eleven feet high, and are ncarly all devoted to eleetriclty. Steam will be brought frora the new boiler house in the vicinity, both for heating purposes and for power. It is proposed to put into the engine room a fifteen horse power englne of the best type for the exclusive use of the ment. Piers in abundance are provlded fur Instruments, and the west end of the building will be kept nearly free from iron. Ou the first floor, provisión lias been made for a larsre extent of slate tables supported on stone corbels set in i lic wiills. The floorsare of u n usual stability, having 3x12 in. and 3x14 in. floor joists, placed with centers one foot apart and strongly bridged. A matched diagonal pine floor will be covered with one of narrow maple. All partitions in the basement and all but one on the first I floor are of brick, without piaster. The lecture room will aeat comfortably one hu nd red and twenty-flve persons, and I will be arranged for darkening by means of the most recent and approved plans. It is proposed to place a storagej.battery in the battery room, both for experimental purpoges and for llghting the building. Dynamos and electrlc motors of di fferent types will be provided. Someofthe best instrumenta of Kni; and Oerman makes for measuring resistance, current, and potential, have already been procured. Wliile other branches of pbyslcs wlll not be neglected, special attention will be paid to electricily and magnetism in connection with the department of ïnechanical engineering. The new building for this ilcMi-i uu-ia is nearly completed is already in use. Here additional power can be obtained, either from a new thirty-live horse power Oorliss entine, or a tweiity-tive power automatic entine built by the depmtment for experimental purposes. The physieal luboratory will be ready for use by October lst, and It is Uien proposed te offi;r to students in niechanioil engineering special coursek in electrical work, which may lead to the degree of electrical engineer. Since the electriCül engineer is in a large part a meclianical engineer, students in the univenity Wlll have ampie opportunity to secure just sucli instruction, laboratöry practice, and shop work aa are needcd to fit thera for a professional career In applied electficity. Such students will tind open to tlii-ni all the advantages which the verslty offers in language, mathematica, chemistry, and physics; imd thls should be stimulate in the pursuit of thelr professional studies by the knowledge tliat the university has had under its tuition in pist years, two men whose names are now at distiiiKuished In applied electricity Charles F. llrusli and Professor Amos E. Dolbear, the one as uu un der gradúate, and the otlier as a postgraduate student. This pían of providing technical courses in uur leuding universities, Iu3tead of estabÜHliiüg schools devoted to each specialty, is to be commended on the ftcore of economy, and particularly because of the extensive and varied advantages which such iiistitiirions afford.
