_Passanante._--Passanante, the would-be regicide of Naples, has no morbid hereditary antecedents.[429] At the age of 29, his height was 1·63 m., and his weight 51½ kilogrammes, _i.e._, 14 kilogrammes less than the Neapolitan average. His head may be described as almost sub-microcephalic--cephalic index 82, probable capacity 1513. His features show the characteristics of the Mongol and the _cretin_--small and deeply-set eyes abnormally far apart, zygomatic bones highly developed, beard scanty. The pupils show a low degree of mobility; and the genitals are atrophied--a fact connected with that of almost complete anaphrodisia. On the other hand, the liver and spleen are hypertrophied, which partly explains the increase of the temperature (varying from 38° to 37·8° at the arm-pits) the weakness of the pulse (88), and the very slight degree of strength, which, moreover, is less on the right side (60 kil.) than on the left (78 kil.). This last fact--which perhaps arises from an old burn on the hand--is most important, because rendering the complete carrying out of the crime improbable, especially taking into account the clumsy weapon with which he was armed, and the unfavourable position which was the only one he could take. The sensibility was perverted--the tactile presenting 5 mm. on the back of the hand (where the normal sensitiveness is from 16 to 20), and 7 on the forehead, where it is usually from 20 to 22 (that on the palm of the hand was not registered). On the contrary, the sensitiveness of the skin to puncture was much weakened. In prison he had attacks of delirium accompanied by hallucinations. All these characteristics are clear indications of disease, both in the abdominal viscera, and in the nervous centres. This result is even more evident from the psychological study of the case. A merely superficial examination might have induced the belief that his affections and moral sentiments were normal. He showed, indeed, a horror of crime, lived a most frugal and abstemious life; and, while sometimes over-religious, sometimes exaggeratedly patriotic, always appeared to prefer the advantage of others to his own. He thus presented to those unversed in the study of mental pathology, the appearance, as it were, of a martyr to an idea which had been maturing for years, the mouthpiece and tool of a powerful sect, who might call for execration politically, but as an individual commanded respect.
