The Chemical Laboratory was built in 1889. The building is a plain rectangular structure, about 170 feet long by 86 feet wide. A new Assay Laboratory, 55 by 44 feet, and a Milling and Leaching Room, 35 by 100 feet, will be ready for use in Lent Term, 1901. There are also open and covered yards for out-door operations. The small lecture room will seat 120, and the larger one about 200 students. The Junior Laboratory contains 40 benches, and the Senior Laboratory will take about 60 advanced students. There are also separate rooms for spectroscopic and gas analysis for photography and for research work respectively. A room is set apart for Chemical Collections, and for old forms of apparatus, &c., which may be of historical interest. The building is provided with the electric light throughout the upper floor, and the gas engine for driving the dynamos is attached to shafting connected with the grinding machines, apparatus for the liquefaction of gases, and similar appliances necessary for a large laboratory. Leads are carried to convenient places in the laboratories, so that if necessary the full power of the dynamos may be used for experimental purposes. Special efforts have been made to give the students the benefits of modern improvements and appliances, and particularly those which tend to save time; draught cupboards, filter pumps, exhaust pipes, and similar conveniences are fitted to each bench. A number of larger hoods and draught cupboards for combustions, sulphuretted hydrogen gas, water baths, and ovens are also provided. There are three balance rooms, each 21 by 16 feet, provided with balances for different purposes, which, to prevent vibration, rest on slate benches, supported upon stone brackets. The Metallurgical Laboratory contains 44 fusion and muffle assay furnaces, and an experimental reverberatory furnace with a bed 6 feet by 4 feet. The plant for the concentration and treatment of metalliferous ores includes a set of stamps, Gates' rock breaker, Rogers' crushing rolls, Chilian mill, Carter's disintegrator; elevator; trommels, samplers, amalgamating plates and pans; a Frue vanner, plunger jigs, settling tanks, &c. Also vats and the necessary appliances for the extraction of gold and silver ores by chlorine, cyanide, hyposulphite, and other similar leaching processes. 28.-PRACTICAL COURSES.

REGULATIONS FOR THE CHEMICAL AND METALLURGICAL LABORATORIES. The Chemical and Metallurgical Laboratories are open daily during Term time for instruction in Experimental Chemistry, Qualitative and Quantitative Chemical Analysis and Assaying. Students engaged in private investigations will have to provide themselves with any materials they may require which are not included among the ordinary reagents, also with the common chemicals when they are employed in large quantities. All preparations made from materials belonging to the Laboratory become the property of the Laboratory. No experiment of a dangerous character may be performed without the express sanction of the Professor or Demonstrator. Each student is required to keep full notes of each day's work for the use of the Examiners. The Laboratory hours are from 10 a.m. to 5 p.m. except on Saturdays, when the Laboratory will be closed at 1 p.m. Every student not working with a class is required to enter the time of his arrival and departure in the attendance book. The Fees for instruction in the Laboratory in the case of students who have already attended the introductory practical course, No. 28A, will be found on page 171. 30.-MINERALOGY. Compulsory for Students in Mining Engineering in their Second Year. A course of about twenty Lectures upon Mineralogy will be delivered during Trinity Term.
