A wooden cabinet of 64 drawers for  31/4" glass projection slides. The top four rows accommodate over 2000 slides, each 82 mm (3 1/4") square. There are about 2000 slides covering a wide range of Physics related topics. They were used in lectures in the two large lecture theatres in the Parnell Building which had been designed without windows for this purpose. Some look commercial, other look like photographs of illustrations in books. The lower four rows of drawers contain assorted electronic components used by the lecture demonstration staff for construction and repair.
