The volume of the Irrenfrennd commences with an article on the writing of the insane. The following conclusions are quoted from a pamphlet by Dr. Th. Güntz :— “1. The writing of the insane exhibits various deviations from what is normal, both as regards quantity and quality. 2. These deviations are important in so far as they frequently give the first indication of the commencement of insanity. 3. They often give the best key to the aetiology, genesis, and duration of the disease. 4. They frequently complete or correct our conception of the nature of the disease. 5. They furnish a certain test of the advent and progress of convalescence.”
