[77] There are, however, no special nerve endings (Krause corpuscles), as was formerly supposed. The nerve endings in the genital region are the same as elsewhere. The difference lies in the abundance of superposed arboreal ramifications. See, e.g., Ed. Retterer, Art. “Ejaculation,” Richet’s Dictionnaire de Physiologie, vol. v.

[79] Sensations of pleasure without those of touch appear to be normal at the tip of the penis, as pointed out by Scripture, quoted in Alienist and Neurologist, January, 1898.

[82] Hyrtl states that the name labia was first used by Haller in the middle of the eighteenth century in his Elements of Physiology, being adopted by him from the Greek poet Erotion, who gave these structures the very obvious name cheilea, lips. But this seems to be a mistake, for the seventeenth century anatomists certainly used the name “labia” for these parts.
[83] Bergh tentatively suggests, as regards the pubic hair, that its appearance may be due to the upright walk in man and the human position during coitus, the hair preventing irritation of the genitals from the sweat pouring down from the body and protecting the skin from direct friction in coitus. (In both these suggestions he was, however, long previously anticipated by Fabricius ab Aquapendente.) The fanciful suggestion of Louis Robinson that the pubic hair has developed in order to enable the human infant to cling securely to his mother is very poorly supported by facts, and has not met with acceptance. It may be mentioned that (as stated by Ploss and Bartels) the women of the Bismarck Archipelago, whose pubic hair is very abundant, use it as a kind of handkerchief on which to clean their hands.
[84] Routh and Heywood Smith have noted that the pubic hair tends to lose its curliness and become straight in women who masturbate. (British Gynaecological Journal, February, 1887, p. 505.)
[85] Schurig, Muliebria, p. 75. Plazzon in 1621 said that in Italian it had a popular name, il besneegio.
[86] Schurig brought together in his Gynaecologia (pp. 2-4) various early opinions concerning the clitoris as the seat of voluptuous feeling.

[89] The voluptuous sensations caused by sexual contacts producing movements of the womb are probably normal and usual. They may even occur under circumstances unconnected with sexual emotion, and Munde (International Journal of Surgery, March, 1893) mentions incidentally that in one case while titillating the cervix with a sound the woman very plainly showed voluptuous manifestations.
