Other cases of Cantarano’s (_loc. cit._) belong here: mictio even defæcatio puellæ ad linguam viri ante actum; consumption of confects smelling like fæces, in order to become potent; and also the following case, likewise communicated to me by a physician:— Case 70. A Russian prince, who was very decrepit, was accustomed to have his mistress turn her back to him and defecate on his breast; this being the only way in which he could excite the remnant of libido. Another supported a mistress in unusually brilliant style, with the condition that she eat marchpane exclusively. Ut libidinosus fiat et ejaculare possit excrementa feminæ ore excipit. A Brazilian physician tells me of several cases of defæcatio feminæ in os viri that have come to his knowledge. Such cases occur everywhere, and are not at all infrequent. All kinds of secretions—saliva, nasal mucus, and even aural cerumen—are used in this way and swallowed with pleasure; and oscula ad nates and even ad anum are indulged in. Dr. Moll (_op. cit._, p. 135) reports the same thing of a man affected with contrary sexuality. The perverse desire to practice cunnilingus, which is very wide-spread, probably frequently has its root in masochistic impulses. Palanda (_Archivio di Psichiatria._ x, fascicolo 3, 4) relates the following case:— Case 71. W., aged 45, predisposed, was given to masturbation at the age of eight. A decimo sexto anno libidines suas bibendo recentem feminarum urinam satiavit. Tanta erat voluptas urinam bibentis ut nec aliquid olfaceret nec saperet, hæc faciens. After drinking he always experienced disgust and ill-feeling, and made firm resolutions to do it no more in the future. Once he had the same pleasure in drinking the urine of a nine-year-old boy, with whom he once practiced fellatio. The patient suffers with epileptic insanity. The cases described in this group form the complete counterpart to group “_d_” of the sadists. Still other older cases belong here, which Tardieu (“Étude médico-légale sur les attentats aux mœurs,” p. 206) observed in senile individuals. He describes as “Renifleurs” persons “qui in secretos locos nimirum theatrorum pasticos convenientes quo complures feminæ ad micturiendum festinant, per nares urinali odore excitati, illico se invicem polluunt.” The “Stercoraires” that Taxil (“La prostitution contemporaine”) mentions are, in relation to this subject, unique. Finally, space is here given to the following case, reported to me by a physician:—
