Nolan[84] has made an analysis of 646 first admissions to Matteawan during a period of six years (1912 to 1918). Forty-eight per cent of these were found to have been born in foreign countries. A striking observation was the large proportion of male cases born in Italy (10.8 per cent) and the female cases born in Ireland (11.7 per cent). Of the various races represented it was noted that the African, which was only responsible for 3.9 per cent of the admissions to civil hospitals, constituted 7.4 per cent of the Matteawan admissions. The races having the largest representation were the Irish (18.7 per cent), the Italian (12.4 per cent) and the Hebrew (10.8 per cent). The mixed races constituted 11.3 per cent of the admissions as compared with twenty-three per cent of the cases reported from civil institutions. Among the male cases 11.4 per cent were charged with disorderly conduct and 26.47 per cent with vagrancy. Of the women, eighteen per cent were charged with disorderly conduct, 16.4 with public intoxication and 39.8 per cent with vagrancy and prostitution. These three groups represent 74.2 per cent of all of the female cases admitted. Of the 646 criminal acts causing commitment, 34.1 per cent were classified from a legal point of view as felonies and 65.9 per cent as misdemeanors. Only 5.3 per cent were charged with murder, manslaughter, etc. Of the various psychoses represented by these cases 26.9 per cent were diagnosed as dementia praecox, seventeen per cent as alcoholic psychoses, 14.7 per cent as constitutional psychopathic inferiority, 7.3 as mental deficiency, 8.3 as manic-depressive psychoses, 11.3 as general paresis, 3.6 as senile psychoses, 2.0 as paranoia or paranoid conditions, 2.2 as epileptic psychoses, and 1.4 per cent as not insane. The alcoholic, constitutionally inferior and mentally defective group constituted thirty-eight per cent of the total. Of the 165 cases diagnosed as dementia praecox it is interesting to note that eleven were charged with homicide, ten with assault in the first degree, fifteen with burglary, thirteen with petit larceny, fourteen with disorderly conduct, and sixty-six with vagrancy or prostitution. Of the seventy-four cases of general paresis thirteen were charged with petit larceny, eleven with disorderly conduct, and twenty-nine with vagrancy or prostitution. The homicides and assaults were committed principally by the alcoholic, dementia praecox, constitutionally inferior and the defective cases. The burglaries and larcenies were committed largely by patients diagnosed as suffering from general paresis, dementia praecox and constitutional psychopathic inferiority.
