In sixteen cases the zygomatic processes were unequal and very prominent. There were fourteen other asymmetries of the face. Three heads were Mongoloid (one Irish-Celt, one Swiss, and one Scandinavian). There are Mongoloid race types in the regions where all three come from. Sixteen were epignathic and eleven prognathic. In one there was arrested development of the lower jaw, and in four arrested development of the face bones. The nose was abnormal in six. There were sixteen brachycephalic and thirteen mesaticephalic skulls. There were no dolichocephalic skulls. There were three with oxycephalic skulls, of whom one was a Celt, one a German, and one a Scandinavian. There were eighteen dome-type skulls, of whom seven were Irish-Celts, five Celtic-American, one English Anglo-Saxon, one American Anglo-Saxon, and one German-American. There were four tectocephalic skulls, of whom one was an Irish-Celt, one an Anglo-Saxon American, and one a Scandinavian. There were three platycephalic skulls, of whom two were Celts and one a Scandinavian. There was a plagiocephalic German and a stenocephalic Celt. One skull had a protuberance at the bregma. Twelve occiputs were flattened, and in four of these there was no tubercle; eighteen had an enormously developed occipital protuberance. The percentage of deformities of the jaws was large. Twenty-nine had defective ears. Normal ears were present only in a member of a family which had furnished one mother and two sisters to the institution. The direct hereditary history of prostitutes is excellently illustrated in Marie Duplessis, idealised by Alexandre Dumas in _La Dame aux Camélias_. Her paternal grandmother, who was half prostitute, half beggar, gave birth to a son by a country priest. This son was a country Don Juan, a peddler by trade. The maternal great-grandmother was a nymphomaniac, whose son married a woman of loose morals, by whom a daughter was born. This daughter married a peddler, and their child was Marie. She had the confidence-operator tendencies of many of her class. She died childless, early in life, from consumption.[255] With their ancestry, habits, perverse instincts, prostitutes cannot be cured or reformed by the enforcement of municipal ordinances. Though those of criminal and congenital type be taken from their surroundings and placed where they can earn an honest livelihood, they soon go back, voluntarily, to their old mode of life. An allied class, belonging to a still blacker phase of biology, are the sexual perverts. The congenital form associated with the stigmata of degeneracy, as already shown, is an expression of the defective line whence the victim has sprung. The congenital types are, like the similar types of the prostitute, victims of inherited defects. The sexual pervert may be divided into precisely the same classes as other criminals. The congenital type often links degenerate lunatics, epileptics, &c., with a born criminal class.
