1. "Dr Pavlov and some of his workers. It is so cold, all must wear overcoats. I am seated between Dr Pavlov and his oldest pupil, Prof Savitch."

2. "Dr Pavlov talking in one of the operating rooms. I am behind him, Dr Zelheim in front of him."

3. "Snapshot I made of Dr Pavlov and his wife."

4."The concrete suspended room, with door open and dog in position. The operator and the switchboard are on the outside of the concrete room. The bldg is surrounded by a moat 5 ft deep filled with sawdust to prevent reverberations from the street. When the door is closed to the concrete room no external stimulus reach the dog except stimulation by the operator at the switchboard, the operator looks at the dog through a periscope but the dog cannot see him. The flow of saliva is registered by a manometer on the outside of the door. The dog can be fed as well as stimulated from the switch board. The concrete room has double walls, each 1 ft thick, separated by air cushions."

5. "Manometer reading on outside of door to dog room, and operator looking through periscope at dog inside. Dr Pavlov seated."
