_Pierre Bayle_, in his Dictionary, under _Pierre Arétin_: “There is a _Dialogue between Maddalena and Giulia_, entitled _La Puttana Errante_ (The wandering whore), in which are exhaustively treated _i diversi congiungimenti_ (the different modes of intercourse), to the number of thirty-five. Aretino, though the book has always been printed under his name, disowns it, declaring it to be the work of one of his pupils named Veniero.” _Brunet_, Manual du Libraire (Book dealer’s Handbook). “The _Puttana errante_, a little book, very rare, quite worthy of Aretino in view of the obscenities it contains, but which has been erroneously attributed to him. Lorenzo Veniero, a Venetian nobleman, is the real author. He published it to avenge himself on a Venetian courtesan named Angela, whom he designates under the insulting name of Zaffetta, that is to say, in the Venetian dialect, daughter of a police-spy.” [_Bayle_, _Forberg_ and many other writers have confused the _Puttana errante_, a poem by Lorenzo Veniero and a burlesque parody of the Romances of chivalry, with the _Dialogue between Maddalena and Giulia_, a prose work to which the Elzevirs gave the title properly belonging to the poem. Neither one nor the other is the work of Pietro Aretino. See note at end of vol. VI. of the _Dialogues du divin Pietro Aretino_ (Dialogues of the divine Pietro Aretino), Paris, Liseux, 1879, 3 vols. 18°, and London, 1880, 3 vols. 18°.

This is, properly speaking, to effect copulation; but there are various ways of doing it. As a matter of fact copulation can be effected:—the man face downwards with the woman on her back, the man on his back with the woman face down, the man on his back with the woman turning her back to him; the man sitting with the woman turning her face towards him, sitting with the woman turning her back to him; the man standing or kneeling with the woman turning her face towards him, standing or kneeling with the woman turning her back to him. Let us examine each of these methods separately. Coition with the man face down on the woman who lies on her back is the ordinary method, and the most natural. Aloysia Sigaea says:
