The type of cases received at an institution exclusively for insane convicts is naturally quite different, as shown by the admissions to the Dannemora State Hospital in New York. Of 185 admissions covering a period of three years the principal psychoses represented were dementia praecox, forty-one per cent, constitutional psychopathic inferiority, nineteen per cent, manic-depressive psychoses, eight, mental deficiency, nine, alcoholic psychoses, five, paranoid conditions, four per cent, etc. Experience has shown that the defective criminal classes are not suitable cases for either penal institutions or hospitals for the insane. They are unable to adapt themselves to prison discipline or hospital routine and prefer to associate only with persons of their own kind who are given to foolish boasting of their crimes as their least harmful diversion. They are entirely unappreciative of any efforts made on their behalf to improve their condition or fit them in any way for the requirements of society. They are strongly inclined to unprovoked cruelty to others. Often they manifest an apparent interest in religious services, thinking it may lead to some preferment, but not for any moral reason. They are notoriously untruthful, unreliable and exhibit a low cunning which often deceives those not familiar with handling individuals of that type. Curiously enough they are exceedingly critical of others and quick to notice their shortcomings. Sexual perversions and immoral conduct are only too common. Prostitution, as has already been shown, is one of the most common failings of the female delinquent. An interesting but superficial knowledge of legal matters is noted very frequently and paraded with a remarkable degree of egotism which is difficult to understand. It is comparatively an infrequent occurrence for a prisoner to admit that he is guilty of the crime of which he has already been convicted by a court. Only a few years since, a prisoner at Sing Sing wrote the Governor of New York suggesting that his release was indicated as a moral procedure for the good of the institution, as he was convinced from information obtained from others that he was the only guilty man in the establishment. The habitual criminal takes little, if any, interest in his own relatives or family except when he is in confinement, and feels no home ties. There is a curious lack of appreciation for the gravity of his own offense and he always complains of a "frame up" and asserts that he has not had a square deal. Homicides even are always explained in an attempt to show that they were justifiable or unavoidable. The most vicious of assaults are often committed on their fellow prisoners without any provocation of consequence. Experience shows that as a rule they are incapable of any sustained effort and accomplish little or nothing when left to themselves. Tendencies to crime show not only a marked suggestibility but a degree of impulsiveness and a lack of self control which is
