C1&C2: Very good condition
Dr. Paul Valiant (in white lab coat) is dangling a white lab rat by the tail, about to lower it into a container. Similar to photos 03.04.0118 and 03.04.0119. In this experiment rats pressed a lever for a nip of alcohol. Valiant was studying how the rats reacted when they had to work harder and harder, elevating their stress levels, to get the same quantity of alcohol.
