Many workers are engaged in the study of various physiologic reactions in psychotic patients. Relatively little investigation along these lines has been done in psychoneurotic patients. This is particularly regrettable as one is frequently confronted clinically with patients whose symptoms depend on a mixture of organic and psychogenic factors.

The value of this concept would be greatly enhanced if accurate information were available with regard to the physiology of the galvanic skin reflex. It is known that the reflex has a close relation to sweating, but unfortunately the
