1. The differential diagnosis of general paralysis of the insane and psychoses with arterio-sclerosis or somatic diseases may be difficult and depend to a great extent upon laboratory examinations of the spinal fluid.2. General paralysis of the insane is frequently the cause of the first admission to hospitals of patients 60 or more years old; in this series 8 per cent of all admissions due to the disease.3. The cases studied in this report indicate that the period of incubation, duration of mental symptoms, and prognosis for periods of improvement is about the same with these old people as for the general average of the disease.
