_Tactile sensibility._--On the tongue the two points of the _esthesiometer_ are perceived only at a distance of five mill. In general the sensibility is very feeble. Localisation very inaccurate; impressions on one side often referred to the other. _Sensibility to pain._--Advanced hypoalgesia, while reiterated punctures fetching blood are felt as slight touches. Burns with a lighted cigar are little if at all felt; but there is some dissimulation on the part of the subject. _Thermal and meteoric sensibility._--Apparently abolished. There has been no opportunity for electrical examination. _Sight._--Does not distinguish colours well; sees red best. Pupils react imperfectly. _Hearing._--On the right side says he cannot hear a watch in immediate contact; on the left only at a short distance. In other ways his hearing has been found to be defective. _Smell._--Does not distinguish odours, of which in many cases he has no knowledge. Ammonia alone, deeply inhaled for a few seconds, causes slight lachrymation on the right side. _Taste._--Perceives vinegar, but not salt, bitter or sweet substances. On offering him half a glass of decoction of cinchona, and telling him that it is wine, and then another of vinegar, he swallows it all eagerly without any indication of disagreeable sensations. On giving him a bitter substance, and telling him it is sweet, he repeats that it is sweet, and _vice versâ_. Appetite voracious; digestive functions normal. Circulation and respiration weak. PSYCHICAL EXAMINATION. Ideas very limited. No imagination or æsthetic sense. Memory very weak, limited to the most elementary and primitive cognitions. Will feeble, in the absence of any morbid impulse. Moral and affective sentiments almost entirely absent. No disposition to occupy himself in any way; tendency to idleness and vagabondage. Unrestrained onanism, to which he formerly gave way four or five times a day, now only about twice a day, because, as he says, he is no longer strong enough. He confesses this without the least shame, with complacency, almost with pleasure. He is not without a certain shrewdness, which is, however, easily discovered. He seems to have learnt from fellow-prisoners to pretend to feel nothing, and to be ready for anything. He is capable of dissimulation, and of simulating at certain moments a state of feebleness beyond what he feels. In his cell he usually walks up and down with short, bent head, and surly look. He is only aroused in moments of anger and violent impulsion. He is often discontented with his food, and throws it away, breaking out into howls rather than cries, and destroying everything--table, stools, etc. In this condition any opposition only renders him more savage. Gentle methods often succeed better, especially when the stage of exhaustion sets in.
