The author has studied the condition of the genital sense in 108 general paralytics in relation to age, form of mental disorder, etc., and draws certain interesting conclusions. He finds that, for example, the self-satisfaction of general paralytics and their delusions of great physical strength are not due to genital over-activity. That disorders of the genital sense are not related to alterations of touch sensation or of sensation to pain, as has been held by some observers. In seven cases, especially where delusions concerning the genital organs were prominent and spontaneously related (notes given), it appears clear after reading the account given that the genital delusions have no physical basis, and do not seem to be related in any way with the state of the genital organs. Dr. de Montyel finds no relation either between the condition of the genital sense and the subjective sensations felt in the skin by certain general paralytics. Alcohol, of all causes, apparently is most frequently responsible for alterations in the genital sense, more especially in the direction of increase.
