a second table can be set inside this, giving 
places for fifteen or twenty more. The centre 
of the room is in part occupied by a dissecting

and a chemical table. ‘The latter is supplied 
with the reagents and appliances for practical 
work in elementary chemical physiology. The 
dissecting-table is for the dissection of ani- 
mals, such as cats and dogs, which are of a 
size not to be conveniently handled at the reg- 
ular work-places on the wall-tables: it has a 
slate top, and is provided with a sink and 
water-tap between every two 
students. The inner side of 
the room has, against the wall, 
tables for scales and the warm- 
water oven; a large hood for 
the performance of chemical 
operations calculated to give 
rise to noxious vapors; and a 
dumb-waiter leading to the 
basement, on which articles 
can be sent up from the store- 
rooms there when called for. 
Near the centre of the room is 
a chute, lined with plate-glass 
(so as to be readily kept clean), 
and passing direct to the fur- 
nace-room below. Through 
this chute all refuse is at once 
got rid of. The floor of the 
room, and of all others in the 
building in which messy work 
has to be done, is of asphalt, 
and the walls of hard cement to a height of 
two and a half feet. Thus no spilled blood 
or other offensive matter is absorbed; and the

floor can be flooded with water, and thoroughly 
cleansed, whenever desirable. 
The work to be done in this room annually 
is as follows: by first-year stu- 
dents, a thorough macroscopic 
and microscopic examination of 
about twenty-five selected vege- 
table and animal organisms illus- 
trative of the course of lectures 
on general biology, and a study 
of the embryology of the chick ; 
by second-year students, a 
course in practical animal phys- 
iology and histology a little 
more extended than that given 
in Foster and Langley’s ‘ Prac- 
tical physiology,’ but essentially 
similar to it, and the thorough 
dissection of a dog or cat. 
The second floor (see plan, 
fig. 2) contains the following 
rooms: a laboratory for research 
and advanced study in animal 
morphology, and a correspond- 
ing room for botanical work; a 
photographing-chamber, with heliostat and 
other appliances for micro-photography ; a li- 
brary of biological text-books, monographs, 
and journals ; a small lecture-room (to be used 
for the present as the laboratory of psycho- 
physiology) capable of seating about thirty ; 
an assistant’s private room; a museum con- 
taining such typical osteolcgical and other
