and flora, made by the members of the field- 
club ; and a store and preparation room for the 
curator of the museum. 
The third floor (see plan, fig. 3) contains 
three main work-rooms for advanced students, 
— one for animal histology, one for physiologi- 
cal experiment on invertebrates and the lower 
vertebrates, and one for experiments on warm- 
blooded animals. The room for the latter 
purpose communicates directly with the hy- 
draulic elevator, which has also doors opening

The building being heated by steam supplied 
from a boiler in the neighboring chemical labo- 
ratory, the basement (see plan, fig. 4), which 
is well lighted, is left free for use. The scien- 
tific work-rooms in it are, a large, well-equipped 
room for advanced study in chemical physiol- 
ogy, a balance-room, and a room for the study 
of animal electricity. The basement also con- 
tains a suite of three rooms, which form the jani- 
tor’s headquarters, where he has charge of the 
necessary stock of chemicals and glassware, and

directly on the corridor of each floor, and runs 
to the basement: there is consequently no 
carrying of animals or their remains up or 
down the stairways. ‘The other rooms on the 
third floor are, a dark chamber for spectro- 
scopic work, for experiments in physiological 
optics, etc.; the director’s private room; a room 
for the myograph ; an assistant’s private room ; 
the mechanics’ shop, for the construction and 
repair of instruments; and a small balance- 
room, containing also a case with a supply of 
chloral, curare, morphia, and other drugs fre- 
quently employed in physiological experiments. 
has also a carpenter’s bench, at which he does 
any simple bit of carpentering required. From 
one of these rooms a shaft two feet square runs 
to the top of the building, communicating with 
each floor. Through this shaft it is intended 
to run wires to various work-rooms, transmit- 
ting electrical currents for the running of ~ 
chronographs, and for similar purposes. The 
shaft was also planned in the hope that ulti- 
mately the clock-work of kymographs and such 
instruments will be replaced by electrical energy 
generated by an engine and dynamo in the base- 
ment, and distributed thence over the building.
