Psychological Exhibit for the World's Fair.

Professor Jastrow of the University of Wisconsin has just left Yale, having been there in the interests of the psychological exhibit at the World's Fair. He is at the head of the psychological department of the exhibition and is visiting the New England Colleges in order to explain the nature of the exhibit and to request each university that he visits to send an exhibit.

The Yale exhibit will be in the nature of charts representing the discoveries made in physiological psychology during the past year and will be sent to Chicago about the first of June.
