NOTES AND DISCUSSIONS 
The window of the room is made of four different thicknesses of plate glass. 
Every pane is set in felt, and is structurally isolated from the others. Every one 
rests upon a structural unit that has no connection other than a felt or sawdust one 
with the other units. The window greatly increases the usefulness of the room 
and does not noticeably decrease the soundproofing. When the window is not 
in use it is closed from both sides by felt and insulite shutters. 
Fig. 6. Detail of the Construction of the Doors of the 
Soundproof Room 
The room is entered, as is shown in Fig. 2, through two double doors, the 
construction of which is shown in detail in Fig. 6. The doors are beveled, and 
the edges are covered with heavy hair-felt. The inner side of the doors is covered 
with insulite, and the outer side with sheet iron and insulite; they are filled with 
sawdust. The doors do not lock; they are held shut by levers, which draw the 
doors tightly into the beveled and felt-lined door-frames and may be operated 
from either side. Karl M. Dallenbach 
The Skidmore College Laboratory of Psychology 
During the forepart of the summer of 1930 Skidmore College acquired a large 
and valuable estate on which were located several substantial buildings. One of 
these was a two-story brick and stucco bam 50 x 114 ft.; another, close by, was a 
brick garage about 32 x 42 ft. with high walls and high pitched roof. The garage 
will be remodelled for work in comparative psychology; at present it houses the 
motor-generator for D.C. to supply the laboratories in the larger building. 
The first floor of the larger building—formerly used as a stable for high bred 
horses—was made over for the secretarial department of the college. The second 
floor having apartments for servants and large storage spaces for grain and hay 
was alloted to psychology. This floor contains nearly 5400 sq. ft. The writer 
with the assistance of Dr. Hobbie, Superintendent of Grounds and Buildings, 
divided this floor space into 10 rooms as shown in the floor plan (Fig. 1). 
The east-west location and the original form of the building directly favored 
the space arrangement and relative position of the rooms that would best serve 
the requirements of a psychological laboratory, e.g. the store room, lecture room, 
and soundproof rooms not requiring direct sunlight are located on the north side; 
and the elementary and advanced laboratories and dark room are placed on the 
south side, receiving full benefit of sunlight. The rooms and corridor are well 
lighted, doors are one-half glass except those to the dark room and soundproof 
rooms. The building is heated by a self-regulating oil burner and each room has
