which are arranged in handsome glass cases in most 

 convenient form for exhibition. Part of the collection, 

 including specimens of gold, silver, and diamonds, is 

 kept in a safe in another building. The third floor of 

 the building is entirely occupied by the chemical labora- 

 tories and the private rooms of professors. The room 

 for qualitative practice occupying the north side, has 

 accommodations for one hundred students. The lab- 

 oratory for quantitative practice is on the east end 

 of the building, and has places for seventy students. 

 Each place is provided with gas, reservoir and dis- 

 tilled water, and suction for filtration, supplied by 

 the air pump in the basement. Oxygen, hydrogen 

 and blast are supplied in both rooms. There are besides, 

 rooms for special experiments, a photographic labora- 

 tory and weighing rooms. The rooms for assaying are 

 in the north end of the basement, and are completely 

 equipped with furnaces, crucibles, etc. 



The entire building is ventilated by a large fan in the 

 basement, connected by flues with most of the rooms. 

 Electricity is generated by dynamos in the basement, 

 the power for this as well as for driving some light ma- 

 chinery being furnished from Sibley College by an 

 underground connection. On the rear of the main 

 building a long one-story brick building has just been 

 erected to be used as a laboratory for students in ap- 

 plied chemistry, where the practical operations of chemi- 

 cal manufacture will be illustrated.
