laboratory of pharmacodynamics on the first floor, and to the large laboratories on 

 the second floor devoted to pathology, where microscopical work is done, the 

 north front of these rooms facing on the courtyard being made almost wholly of 

 glass, and extending higher than the front, so that steady north light will be 

 thrown to the back of the room. 



The first floor of the new laboratories will be devoted to physiology and 

 pharmacodynamics. 



The second floor will be devoted exclusively to pathology. An examination 

 of the commodious plans will disclose the purpose of the pathological laboratory. 

 After providing for lectures upon general topics in pathology, the chief provision 

 is for laboratory instruction. The entire north front of the building is devoted 

 to laboratories for advanced students in pathology and pathological bacteriology, 

 and to the special research and assistants' rooms. Each of the advanced labora- 

 tories measures 31 x 44 feet. The east wing accommodates the laboratory of 

 experimental and chemical pathology, while the west wing is occupied by the 

 museum of pathological specimens. This latter, which measures 44 x 65 feet, 

 adjoins the demonstration hall of morbid anatomy, which hall communicates 

 with the general pathological-histological laboratory. The last laboratory, the 

 front of which is to consist almost entirely of glass, is located in a section of the 

 building looking north into a spacious court. This room, 37 x 100 feet, will seat 

 one hundred students, and will be devoted entirely to microscopical work, for 

 which, on account of the excellent lighting, it will be admirably adapted. In 

 order to combine in one harmonious whole the study of the microscopical 

 features of diseased organs and the gross alterations in them, the pathological- 

 histological laboratory, the laboratory of morbid or gross pathological anatomy, 

 and the museum of pathology are made closely communicating and freely 

 accessible one from the other. Another section of the building, of equal size 

 with the first, and also looking north into the court, is subdivided into three 

 smaller laboratories for the instruction in comparative (pathology of animal 

 diseases), neurological (pathology of nervous diseases), and surgical pathology. 

 The same method of lighting, with enormous glass windows, is to be carried out 

 in this group of laboratories. Finally, the west wing of the building will also 

 provide for photographic and micro-photographic outfits. 



Besides the numerous laboratories, research rooms, etc., there are four lecture 

 rooms in the building. The two marked " Demonstration Rooms " on the plan 

 each seats 184 students. These lecture rooms communicate with two prepara- 

 tion rooms each. At the rear of the building there are two large lecture rooms, 

 each seating 400 students. To avoid confusion between lectures, the corridors 

 and stairways are so arranged that one class enters the large lecture room from 

 one side as the other class leaves it from the opposite side. Students enter 

 these rooms from a landing at the main stair, midway between the first and 

 second floors. The floor of the lecture room is on a level with the basement, 

 and the lecturer will enter directly from the basement level, and all specimens 

 needed to illustrate the lectures will be brought through the entrance, thus saving 

 the crossing of the halls through which classes move. 



The equipment of the laboratory will be adeq.uate and in keeping with the
