Farther: All authors who have written on the diseases of warm climates, have mentioned the too frequent repetition of the act of venery among the causes of these typhus affections, which have been termed _febris ardens_, _causus_, _yellow fever_, &c. In temperate climates, adynamic ataxic fevers, &c., and very severe acute diseases, have often been known to occur from excesses in venery, or from masturbation. If _satyriasis_ and _nymphomania_ have been regarded as rare diseases, it is only because the meaning of these terms has been too confined to embrace numerous cases which, however, have the greatest analogy with those diseases to which these terms are applied. Generally, these persons are considered as affected with satyriasis and nymphomania, who are irresistibly impelled to coition, and resort, to satisfy their desires, to the most indecent actions, and to the most direct provocations. Thus defined, these diseases are rare; and most practitioners have never seen them. But if satyriasis and nymphomania be regarded as an unusual state of heat, by which one is led to desire and to practise not only coition, but the act of venery in any mode, then the scene enlarges, and these affections deserve to be placed among those which are observed most frequently. We shall adopt the latter sense. In our view, male and female onanists are affected with satyriasis and nymphomania, as much as those to whom these terms are generally applied. In both, the sense of venery, existing to an unusual extent, affects the mind, and incites to dangerous actions, repugnant both to modesty and reason. Onanists do not, like other persons affected with satyriasis, expose their persons, and solicit with voice and gesture those of the other sex: their deranged and delirious imaginations pursue another course. What need have they of the other sex? Their inclinations lead them to solitary indulgence. Their thoughts and actions, however, are not less vile than those of others affected with satyriasis; but they are indulged in secret. Hence, between the satyriasis of books and that of onanists, there is only a difference of form: the foundation is the same. Admit, however, that it be desirable to distinguish this satyriasis from the former, and to give it a special name; is it not better to consider them only as two varieties of the same affection, one of which impels to onanism, the other to coition?
