number of excellent botanical charts. The room is amply jirovided 

 with water, gas and electricity. The laboratory of cryptogamic botany 

 (19x17 feet) is adjoining. The microscope desks are arranged next to 

 the walls under the windows and are of the same plan as those in the 

 larger room. 



The laboratory is fully e(iuipped with the best compound micro- 

 scopes, microtomes, sterilizers, incubators and a large library of micro- 

 scopic slides. A large herbarium case contains the cryptogamic her- 

 barium. 



The biological photographic dark room and the stock room both 

 open off from the cryptogamic laboratory. A full set a photographic 

 apparatus and a well equipped dark room provided with two sinks, 

 washing tanks, etc., and nicely illuminated with electricity and gas, 

 with sliding colored glass windows giving various colored illumination, 

 affords good opportunity for experimental photographic and micropho- 

 tographic work. 



This dark room is used also by the engraving department for their 

 photographic work. 



DEPARTMENT OF ZOOLOGY. 



The General Zoological Laboratory (26x27 feet) is a well 

 lighted room on the second floor with north and east exposure. The 

 work tables are arranged along the two outer walls, the remainder of 

 the floor space being used as lecture room. The room accommodates 

 21 students and each desk is supplied with individual lockers, com- 

 pound microscope and the conveniences for dissection. Charts, models 

 and mounted skeletons, human and comparative, are supplied, and the 

 wall cases contain those specimens which are most useful in demon- 

 strating zoological types. Much of this material is, however, stored 

 away, pending the time when suitable cases can be supplied for its re- 

 ception in the museum. A small reference library is also provided. 



The Advanced Zoolooical LAiiokAiORV (17x26 feet) adjoins 

 the General Laboratory and is lighted from the north and west. The 

 work tables are bracketed to the outer brick walls to insure the steadi- 

 ness necessary for high-power microscopic work. The central floor- 

 space is occupied by a large slate-tojjped table fitted up with the baths 

 and reagents necessary for the embedding the sectioning of tissues for 

 the microscope. Good microscopes of modern pattern, immersion 

 lenses, and several of the most approved types of microtomes, together
