center of the room electric power, light, gas, and compressed air, and generally also water, in which case a secondary waste pipe opens in the floor below.
The benches are movable and interchangeable. They are built up on unit cupboards. These are of two types differing only in height and giving benches 82 and 90 cm high respectively. The drawers are all interchangeable. In many of the laboratories drawplates are arranged between the bench top and the cupboards.
The large lecture-theater is used in common by the institutes of medical physiology and biochemistry whose preparation rooms are situated to the right of the theater and the laboratory of biophysics whose preparation and collection rooms are situated to the left.
The lecture-theater with an area of 12.8 by 13.9 meters and a height of 8 meters has accommodation for 228 students. It is situated in a special wing two stories high (basement and first floor) in the middle of the main wing of the building. The students’ entrance is in the rear with cloakroom in the basement and entrance to the amphitheater one story up.
The lecture-theater has good facilities for every kind of demonstration. In the rear in a special room, separated from the theater to cut off a fire, is placed a lecture cinematographic apparatus with stop and
back motion which can be controlled also from the lecturer’s platform. Another projection apparatus (episcopic and diascopic) is placed in the frbnt part of the theater where also are found arrangements for projecting experiments. The blackboard (4 by 2 meters) is moved hydraulically and the same kind of motion is used also for the darkening curtains and projection screen. The large blackboard is made of wood in an iron frame and covered with a special Danish blackboard covering. The wall behind the blackboard, which has the same covering, can be used as a supplementary blackboard.
The lecture-theater has every kind of electric supply with high-power resistances, large demonstration ammeters and voltmeters for direct and alternating current, and a sensitive galvanometer. The desk has, besides electricity supply, cold and hot water, steam, compressed air, gas; and behind the blackboard is a fume cupboard with artificial suction.
The acoustics of the lecture-theater have been corrected by covering part of the walls with “celotex” and the ceiling with a special porous plaster. Though for architectural reasons the covered area is somewhat smaller than demanded by the theoretical calculation, this has proved very effective.
