The third floor provides the laboratories for the advanced courses and 
a very satisfactory lecture room with raised floor. The lecture table and 
laboratories are fltted with gas, water, direct and alternate current cir- 
cuits. Immediately back of the lecture table is an apparatus room for 
the storage of all demonstration apparatus; adjoining this a photographic 
dark-room. The department office is on the second floor and above it a 
dark-room which will be fltted for photometric w;ork. The short circu- 
lar stairway gives direct communication between the two floors. 
Notwithstanding the fact that the building was originally designed 
for other use we And it remodels into a satisfactory and very conveniently 
arranged physical laboratory.
