The effective teaching of Psychiatry to medical students remains a formidable problem for many reasons apart from the actual methods employed by the teacher. Allocation of adequate time to the subject, the attitude of other teachers and students towards it, the facilities provided by local hospitals, clinics and other institutions alike contribute to the difficulty in establishing Psychiatry as a major subject within the medical curriculum. It is with the problem of teaching method alone that this paper wishes to deal: first to outline the inherent difficulties commonly encountered; secondly to describe the design of structures and equipment found useful in overcoming these difficulties in some measure; and thirdly to point the way for possible future development.

Because of the professional and lay interest in the potential value of glutamic acid in the treatment of mental deficiency the present study has been conducted.

From the section of Lennox Castle Institution, which is devoted to the training and treatment of Male Juvenile Mental Defective Delinquents, 30 patients were chosen. Half of these were treated with glutamic acid and half used as controls.

The analysis is based upon comparison between experimental and control group rather than between paired individuals. As may be seen from the table, the two groups are very similar. There is no significant difference in the age, intellectual capacity, social background or environment.
