Psychoses which render the commitment of mental defectives to hospitals for mental diseases necessary are comparatively infrequent, as is shown by statistics. In the words of the statistical manual, "the most common mental disturbances are episodes of excitement or irritability, depressions, paranoid trends, hallucinatory attacks, etc." Cases diagnosed as showing manic-depressive psychoses or dementia praecox are not shown in the mental defective group. Three and forty-eight hundredths per cent of the admissions to the Massachusetts hospitals during 1919 were diagnosed as psychoses with mental deficiency. During a period of eight years the admission rate to the New York hospitals amounted to 2.8 per cent. The admissions to twenty-one institutions in other states constituted 4.33 per cent of the whole number reported. In 70,987 admissions to forty-eight hospitals in sixteen states the psychoses with mental deficiency amounted to 3.22 per cent of all first admissions.
