The Bone Room and the Lecture Theatre are entered directly from the Dissecting Room. The Bone Room is a lofty room surrounded by a gallery. On the floor, osteological specimens are arranged in revolving cases on long narrow tables. Few anatomical departments can boast of so numerous and so varied an assortment of teaching preparations. The gallery is chiefly devoted to specimens which bear upon the applications of anatomy to the practice of medicine. It is here also that are displayed (1) the large series of models prepared in the department to illustrate cerebral growth and the cranio-cerebral topography of the child and the adult; (2) the series of models representing the anatomy of inguinal hernia, also prepared in the department; (3) the mesial sections of the four anthropoid apes--gorilla, chimpanzee, orang, and gibbon--preparations which are unique. The Theatre is capable of seating 400 students. It is not handsome; but it is comfortable and, most important of all, its acoustic property admirably well adapted for the purpose for which it was designed. There are also a Museum of Surgical and Medical Pathology, and one of Materia Medica. THE CHEMICAL SCHOOL. The Chemical Department adjoins the Medical School, and is in the southern part of the buildings, just within the Lincoln Place gate of Trinity College. The new Lecture Theatre of the School is situated between two groups of Laboratories, and is fitted with all modern appliances for lecture-illustration in the various branches of Chemical Science. The seats are numbered, and are assigned in the order of entry for the different courses of lectures. Behind the Lecture Theatre is a large Demonstration Room, fitted with Assay and Cupelling furnaces and other apparatus, and beyond are the Laboratories for Qualitative Analysis and Preparation. These consist of four lofty and well-ventilated rooms, capable of accommodating 112 students, who work at compartments fully provided with the necessary apparatus tests and materials. Off the larger room of this series are (1) a special sulphuretted-hydrogen chamber, with separate ventilation, (2) a general store, and (3) cases of apparatus used at lectures. These Laboratories, as well as the Lecture Theatre and other rooms, are heated by means of hot water pipes, and the special ventilation required for carrying off fumes, &c., from the different compartments is obtained by the powerful draught of a chimney stack, sixty feet high, connected with the furnace of the heating apparatus. The Quantitative and Research Laboratories and their related rooms are at the east front of the new buildings. The main Laboratory is a fine room, provided with all modern appliances, and adjoining it are special rooms for (_a_) Balances and other instruments of precision, together with the special apparatus required for Quantitative Analysis; (_b_) for Organic Analysis; (_c_) for Pressure Tube work; (_d_) for Gas and Water Analysis, and for Spectrum Analysis.
