blackboards, projecting screens, etc., a dark room for photographic work, a 

 janitor's room, and a suite of apartments for the professor. 



Tlie large windows of the pathological laboratory, each nearly six feet wide, 

 and five in number, face the north, and to facilitate morbid anatomy demonstra- 

 tions very large tables project from each window into the laboratory, the men 

 sitting on both sides of these tables facing one another, and receiving the light 

 from the side. Five such tables divide the class into groups of ten men each, 

 and morbid specimens can be presented to each group from the end of the 

 table. Between the tables, and also between the windows against the walls, 

 there are sinks and microscope lockers. On the opposite side of the room,

lockers are provided for the instruments, slide-boxes, reagents, notebooks, etc., 

 of each man in the class. Each locker measures liix 14x lb inches, has one 

 shelf, and contains a moveable tray in which staining dishes and reagent bottles 

 can be kept. The method of laboratory teaching provides that each man shall 

 take charge of his own reagents, returning them to his own locker at the end of 

 each demonstration, and returning the microscope to its locker, thus leaving the 

 room unincumbered, so that it can be kept tidy and clean with comparatively 

 little effort. 



In the laboratory of bacteriology a more conventional arrangement of tables 

 has been adopted, the men sitting at narrower tables facing the light. Each 

 man has three lineal feet of table room, and is provided with a gas-cock of his 

 own, and shares a water spigot, with a small brass basin below it. with the next
