A supplement to the Onania, [electronic resource] : Or the Heinous Sin of self-pollution, And all its frightful Consequences, in the two Sexes, consider'd, &c. (printed on the same Letter and Paper, to be bound up with either the 7th, 8th, 9th, or 10th Editions of that Book). Containing many remarkable, and indeed surprizing Instances of the Health being impair'd, and Genitals spoil'd, by that filthy Commerce with ones self, which is daily practised, as well by Adults as Youth, Women as Men, Married as Single, as their Letters inserted manifest. Also a curious Piece, (as promis'd) translated out of the Latin, from L. Sckmeider, as it is inserted in the Acta Lipsiensia, concerning the return of the Seed into the mass of Blood, well worth the perusal of Physicians, Surgeons, Anatomists, and all others of Art and Curiosity. And which with an Answer to a late scurrilous Libel, call'd Onania Examin'd and Detected, clearing up the Charges against the Onania, and those especially relating to the Ladies, as several Letters from them shew, compleats all what the Author has to say on this Subject. .
