40 Students Here Serve Duke U. as ESP Guinea Pigs

Forty Harvard students are taking part in a major experiment in long range extra-sensory perception.

Each night, for 16 nights starting last Wednesday, a chart is locked in a laboratory at Duke University, Durham, North Carolina, containing extra-sensory symbols arranged in five rows of five each. The symbols are a star, square, circle, cross and wavy line; and five of each, placed in a random fashion, are used in every chart.

Here at the University, the 40 students are expected to pause during the evening and jot down on a penny postcard their guess as to the arrangement of the symbols being used that night. The postcard in mailed off to Duke the next day.
