Yale's Work in Psychology.

Numerous changes have lately been made in the course in the Yale Psychological Laboratory, with a view to the introduction of a new line of study which will be opened to the undergraduates next year. For the last three years a regular laboratory course in experimental psychology has been offered to graduate students. This has now been perfected and made completely successful. Next year it will be open as a regular elective to the senior and junior classes. The subject of study will consist of a series of carefully-graded exercises in sight, hearing, mental time, &c., which will be performed by each student.
