represent masturbation as the source of all evils. These four writers--the author of _Onania_, Tissot, Voltaire, Lallemand--are certainly responsible for much. The mistaken notions of many medical authorities, carried on by tradition, even down to our own time; the powerful lever which has been put into the hand of unscrupulous quacks; the suffering, dread, and remorse experienced in silence by many thousands of ignorant and often innocent young people may all be traced in large measure back to these four well-meaning, but (on this question) misguided, authors. There is really no end to the list of real or supposed symptoms and results of masturbation, as given by various medical writers during the last century. Insanity, epilepsy, numerous forms of eye disease, supra-orbital headache, occipital headache (Spitzka), strange sensations at the top of the head (Savage), various forms of neuralgia (Anstie, J. Chapman), tenderness of the skin in the lower dorsal region (Chapman), mammary tenderness in young girls (Lacassagne), mammary hypertrophy (Ossendovsky), asthma (Peyer), cardiac murmurs (Seerley), the appearance of vesicles on wounds (Baraduc), acne and other forms of cutaneous eruptions (the author of _Onania_, Clipson), dilated pupils (Skene, Lewis, Moraglia), eyes directed upward and sideways (Pouillet), dark rings around the eyes, intermittent functional deafness (Bonnier), painful menstruation (J. Chapman), catarrh of uterus and vagina (Winckel, Pouillet), ovarian disease (Jessett), pale and discolored skin (Lewis, Moraglia), redness of nose (Gruner), epistaxis (Joal, J.N. Mackenzie), morbid changes in nose (Fliess), convulsive cough of puberty (Gowers), acidity of vagina (R.W. Shufeldt), incontinence of urine in young women (Girandeau), warts on the hands in women (Durr, Kreichmar, von Oye), hallucinations of smell and hearing, (Griesinger, Lewis), intermittent functional deafness (Bonnier), indican in the urine (Herter), an indescribable odor of the skin in women (Skene), these are but a few of the signs and consequences of masturbation given by various prominent authorities.[317] That many of these manifestations do occur in connection with masturbation is unquestionable; there is also good reason to believe that some of them may be the results of masturbation acting on an imperfectly healthy organism. But in all such cases we must speak with great caution, for there appears to be little reliable evidence to show that simple masturbation, in a well-born and healthy individual, can produce any evil results beyond slight functional disturbances, and these only when it is practiced in excess. To illustrate the real pathological relationships of masturbation, a few typical and important disorders may be briefly considered.
