yards. One man devotes his entire time to the care of 
the animals. An aquarium (10 ft. by 21 ft.) located in 
the basement accommodates the cold-blooded animals. 
On the third floor the Department occupies about 
6,000 square feet of space, exclusive of corridors, 
arranged primarily for teaching, though when not 
occupied by students, the rooms are available for re¬ 
search. At the west end of the floor are the two main 
class laboratories, each measuring 26 ft. by 52 ft. (Fig. 
6). Communicating doors are so placed that announce¬ 
ments can be made to both laboratories simultaneously. 
The placing of the laboratory tables is determined by 
the fixtures designed to cany the plumbing and wiring. 
These consist of small sinks with tops 13 inches square 
set at the height of the laboratory tables. Coming up 
from below through the floor and piercing either the top 
or the apron of the sinks are the pipes for hot and cold 
water, gas, and compressed air; the conduits carrying 
the 110-volt direct current, with outlets for a deskjiamp 
and for power; and the two pairs of wires from the 
storage-battery plant, one pair being connected through 
the time-clock. It was originally intended to have a 
sink for each laboratory table; but as the tables are 
movable this arrangement is not immutable. Through 
the elasticity thus permitted, it has been found possible, 
without crowding or confusion, to increase the capacity 
of each of the laboratories from thirty-two to forty 
students (two students working at a table). Each 
laboratory contains a blackboard, two large sinks, 
smoking and shellacking equipment, drying racks, and 
wall cases and shelves for the materials needed by the 
students. A conveniently located issue room com¬ 
municates with the laboratories. 
The remainder of the departmental space on this floor 
is divided into rooms in which is mounted the apparatus 
for the “special” experiments to which the students are 
assigned in rotation. One room (20 ft. by 21 ft.), 
located to the west of the stairway, is equipped for 
chemical experiments, and contains apparatus for ex¬ 
periments on respiration, including recording volu¬ 
metric spirometers, gas analysis apparatus, rebreathers, 
etc.; apparatus for the quantitative study of the knee- 
jerk has also been placed in this room. Two small 
rooms, each measuring 10 ft. by 12 ft., adjoining this, 
contain respectively, transmission sphygmographs for 
the determination of pulse velocity and polysphygmo- 
graphs. A room (20 ft. by 21 ft.) across the corridor is 
designed for experiments requiring chemical technique. 
Connected with this to the east are two small rooms, 
each about 7 ft. by 10 ft., one of which (a dark room)
