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.
