...Crazy. Working on a grant from the Otho Sprague Institute, Dr. Masserman rigged up an automatic feeding apparatus which dropped some food into the feedbox of a glass cage every time a light flashed on. He then trained cats, one at a time, to lift the lid of the feedbox whenever the light flashed. After the cats were conditioned to associate light with food, he shot a harmless blast of air into the cage at the moment the cat reached for the lid. This gale at mealtime frightened the cats. After repeated frustrations the animals associated the feedbox and signal...

Every night the human guinea pigs, after eating "test food," went to bed with a battery of scientific apparatus hitched up to their toes, a microphone strapped to their stomachs. They did not have very comfortable nights. Ohio State Physiologist Hugh Boyd McGlade woke them periodically to ask if they were dreaming. He discovered that dreams were heralded by a "rapid rumbling" below the stomach, a twitching of the right foot. Good food to induce dreams, he found, was bananas. When his guinea pigs ate ice cream, fresh tomatoes or canned pineapple, they neither twitched, rumbled nor dreamed...
Concentrators in chemistry seem unusually satisfied with the setup as it is, and few see where any changes for the better can be made. Although there seems to be a lack of chemical engineering courses in view of the war efforts's demands, the difficulty of obtaining new apparatus and starting courses in the field at this time forbids any change in the setup...
