At other times the cause is some limitation to his tendency to free vagabondage. The animal-like howls are set up; then comes the destruction of everything that surrounds him, and violences of all sorts. When he is interrogated in his calmer moments as to the reason of this, he replies that it is what they do in his country. DIAGNOSIS. _Advanced physical and psycho-physical degeneration. Phrenasthenia. Moral idiocy. Instinctive criminality._ MEDICO-LEGAL AND SOCIAL CONSIDERATIONS. This is the case of an instinctive criminal, a person fatally and immutably impelled to vagabondage, theft, and violence. He bears the characters, physical and psycho-physical, of degeneration, of aberration, of constitutional abnormality, sufficient for recognition. Especially noteworthy are the lambdoidal depression, the marked plagiocephalia and plagio-prosopia, the superior prognathism, and the inferior dental irregularities, the thoracic asymmetry, the pallid complexion, the hypoalgesia, the weakness and perversion of some of the special senses, the unrestrained onanism, the predominant love of vagabondage, the furious and animal-like anger, the destructive tendencies. It is clear that all the admonitions and punishments inflicted during seven years, besides failing to produce any good effects, succeeded in exercising, so to speak, the natural mechanism of his violent impulses, and thus brutalised him still further. He is, therefore, incorrigible. Of this the Military Tribunal of Naples were, as the result of this examination, convinced, declared that our subject is irresponsible, and acquitted him. But does the duty of science end here? Is this verdict sufficient for order and social security? Surely not. This individual, thus constituted, must be regarded as a perpetual source of danger. It is therefore necessary to adopt a mode of treatment which, instead of brutalising him, will endeavour to obtain from him the maximum social utility of which he is capable, while at the same time it will render it impossible for him to injure other persons who are unlike himself. For this purpose sequestration is necessary, the method of moral treatment and the watchful care obtained within a criminal asylum. VI.--The following report, by O. Hotzen (here abbreviated), appeared in the _Vierteljahresschrift für gerichtliche Medicin_, and in the _Archivio di Psichiatria_ for 1889, fasc. 2. Maria Köster died at the age of 22 of tuberculosis; at the age of 18 she had killed her mother with a hatchet; sixty wounds were found in the mother’s body, some of them penetrating the skull. As until then the girl had always been of good character, quiet and hard-working, and on account of her youthful age, she was examined by medical experts in order to ascertain if any morbid conditions had limited her free will.
