wing and five rooms on the second floor of the southeast wing. These rooms are fitted up in the same uniform manner which characterizes the whole institute. With a few exceptions, the separate rooms are fitted up with a view to being used for more than one purpose, as occasion may require.
The basement contains both a joiner’s and a mechanic’s workshop, cleaning rooms, centrifuge rooms, distilling rooms, rooms for experimental animals, and, besides, an electrocardiograph room with an adjoining dark room. The basement also contains a few laboratories with the usual laboratory equipment.
Further, the basement contains a refrigerating room, consisting of two chambers, i.e. a smaller one resembling a locker in which the temperature can be reduced to 15° C. below zero, and in front of this, a larger one in which the temperature can be reduced to 5° C. below zero. The area of the latter measures 2 m2, and it is provided with gas, water, and electric contacts and thus permits of carrying out experiments of various descriptions.
The first floor contains a large number of laboratories, but only a few of these are appropriated to certain particular purposes, such as, for instance, gas analyses, titration, and weighing. One of the smaller first floor
laboratories is fitted up with thermostatic control in which temperatures varying between ordinary room temperature (about 20°) and 40° C. can be maintained. This laboratory, as well as several others, is fitted up with shafts driven by motors at a man’s height along the walls so that the power for pumps, gas meters, or kymographs and the like, is easily accessible.
The middle wing of the first floor contains the large teaching laboratory (Fig. 8) in which are held experimental courses for the students. In connection with this laboratory, there is a large dark room which is used for polarimetry and colorimetry as well as for ophthalmoscopy and the like.
The teaching laboratory is provided with shafts driven by motors along the two longitudinal walls, where there is space for twelve kymographs. At each of these, two students work together. Each working place is provided with gas, compressed air, and electric power of 220 watts as well as of 2, 4, and G volts. The center of the teaching laboratory is occupied by tables on which are placed the instruments required for tests, which the students carry out on their fellow students as subjects, such as plethysmography, pulse tracing, determination of the basal metabolic rate, etc. The
