Rothe, in his investigation of the pubic hair of 1000 Berlin women, found that no two women were really alike in this respect, but there was a tendency to two main types of arrangement, with minor subdivisions, according as the hair tended to grow chiefly in the middle line extending laterally from that line, or to grow equally over the whole extent of the pubic region; these two groups included half the cases investigated. In men the pubic hair normally ascends anteriorly in a faint line up to the navel, with tendency to form a triangle with the apex above, and posteriorly extends backwards to the anus. In women these anterior and posterior extensions are comparatively rare, or at all events are only represented by a few stray hairs. Rothe found this variation in 4 per cent. of North German women, though a triangle of hair was only found in 2 per cent.; Lombroso found it in 5 per cent, of Italian women; Bergh found it in only 1.6 per cent. among 1000 Danish prostitutes, all sixteen of whom with three exceptions were brunettes. In Vienna, among 600 women, Coe found only 1 per cent, with this distribution of hair, and states that they were women of decidedly masculine type, though Ploss and Bartels, as well as Rothe, find, however, that heterogeny, as they term the masculine distribution, is more common in blondes. The anterior extension of hair is usually accompanied by the posterior extension around the anus, usually very slight, but occasionally as pronounce as in men. (According to Rothe, however, anterior heterogeny comparatively rare.) These masculine variations in the extension of the pubic hair appear to be not uncommonly associated with other physical and psychic anomalies; it is on this account that they have sometimes been regarded as indications of a vicious or a criminal temperament; they are, however, found in quite normal women.
