That sexual inversion may be and actually is transmitted, like any other quality, appears to be proved by the history of well-known families both in England and in Germany. That it is not unfrequently exhibited by persons who have a bad ancestral record, may be taken for demonstrated. In certain cases we are justified, then, in regarding it as the sign or concomitant of nervous maladies. But the evidence of ancient Greece or Rome, of what Burton calls the "sotadic races" at the present time, of European schools and prisons, ought to make us hesitate before we commit ourselves to Krafft-Ebing's theory that hereditary affliction is a necessary predisposing cause.[1]

Undoubtedly the instinct is occasionally evoked in some obscure way by the depraved habit of inordinate self-abuse.
