The wall behind the lecture table has in the centre a large wall stink cupboard of 6.40 m length. 

 This is formed of three compartments separated from each other by glass partitions. Each compart- 

 ment has a large sliding window in front, suspended on gut strings and balanced by weights. The 

 table top, the back wall and the sloping roof of the stink cupboard are laid with white porcelain slabs. 

 The right-hand cupboard takes the form of a "through" cupboard, and is closed on the- side facing the 

 auditorium by a frosted glass pane 1.4o m square. The plate of glass serves to receive the projection 

 images from the preparation room. The large central compartment of the cupboard and the left com- 

 partment are fitted out with gas and water leads and water outlet. The taps for these are placed 

 in front under the table top, while the outlets end inside the cupboards at the back above the table top.

 of poplar. These boards are covered over with slate, are suspended on gut cords, balanced by iron 

 weights, and can be adjusted up and down. To the left and right of these blackboards two blackboards
