The importance of the same factor is also shown by the fact that when among women in civilization animal perversions appear, the animal is nearly always a pet dog. Usually in these cases the animal is taught to give gratification by _cunnilinctus_. In some cases, however, there is really sexual intercourse between the animal and the woman. Moll mentions that in a case of _cunnilinctus_ by a dog in Germany there was a difficulty as to whether the matter should be considered an unnatural offence or simply an offence against decency; the lower court considered it in the former light, while the higher court took the more merciful view. (Moll, _Untersuchungen über die Libido Sexualis_, bd. i, p. 697.) In a case reported by Pfaff and mentioned by Moll, a country girl was accused of having sexual intercourse with a large dog. On examination Pfaff found in the girl's thick pubic hair a loose hair which under the microscope proved to belong to the dog. (_Loc. cit._, p. 698.) In such a case it must be noted that while this evidence may be held to show sexual contact with the dog, it scarcely suffices to show sexual intercourse. This has, however, undoubtedly occurred from time to time, even more or less openly. Bloch (_Op. cit._, pp. 277 and 282) remarks that this is not an infrequent exhibition given by prostitutes in certain brothels. Maschka has referred to such an exhibition between a woman and a bull-dog, which was given to select circles in Paris. Rosse refers to a case in which a young unmarried woman in Washington was surprised during intercourse with a large English mastiff, who in his efforts to get loose caused such severe injuries that the woman died from hæmorrhage in about an hour. Rosse also mentions that some years ago a performance of this kind between a prostitute and a Newfoundland dog could be witnessed in San Francisco by paying a small sum; the woman declared that a woman who had once copulated with a dog would ever afterwards prefer this animal to a man. Rosse adds that he was acquainted with a similar performance between a woman and a donkey, which used to take place in Europe (Irving Rosse, "Sexual Hypochondriasis and Perversion of the Genesic Instinct," _Virginia Medical Monthly_, October, 1892, p. 379). Juvenal mentions such relations between the donkey and woman (vi, 332). Krauss (quoted by Bloch, _Beiträge zur Ætiologie der Psychopathia Sexualis_, Teil II, p. 276) states that in Bosnia women sometimes carry on these practices with dogs and also--as he would not have believed had he not on one occasion observed it--with cats. "It seems to me," writes Dr. Kiernan, of Chicago, (private letter) "that what Rosse says of the animal exhibitions in San Francisco is true of all great cities. The animal employed in such exhibitions here has
