ward and you will find either a replica of the other. Suppose first man's organs pushed into him and extending interiorly between the rectum and the vessie; in this supposition the scrotum would occupy the place of the matrice, with the testicles placed at each side of the exterior orifice. The prong of the male would become the throat of the cavity thus produced, and the skin of the prong's extremity, called the foreskin would form the vagina. Suppose, inversely, that the matrice should turn inside out and fall outside, would not its testicles (ovaries) of necessity, find themselves inside its cavity and would not it envelop them as a scrotum? Would not the throat, hidden up to the perineum, become the male member, and the vagina, which is but a cutaneous appendix of the throat, the foreskin?" This is the passage which Diderot has transposed and put au courant with science in his Rêve d'Alembert. This page of literary anatomy retains its expressive value: "Woman has all man's parts, the sole difference is like that between a purse hanging outside and a purse stuffed inside; a female foetus resembles a male foetus, so as to deceive anyone; the part which occasions the error, sinks in the female foetus in measure as the purse extends inward; it is never obliterated to the point of losing its primitive form; it also is the mover of pleasure, it

ogical chain. Parting from link animals which separate into two parts, one sees the sexual organs design themselves in the form wherein they arrive in higher animals of great complexity, such that, in acquiring differences of form and position they retain

ng to get like results by tying the 'foreskin above the gland, like a bag with a cord. Thus man's hand permits him to improve or mutilate his body. Mutilation and sexual deformations, circumcision among Semites and savages, excision of Russian illuminati, transversal perforation of the gland, surgical flattening of the prong, are very frequent. The hand of the chiroptera is shackled, that of quadrumanes has only one sexual r?le, masturbation. It may also serve as a shield against external danger; many quadrumanes, better protected, make the same use of their tail when they curl it between their legs, this is sometimes a psychological gesture, female modesty or refusal, sometimes a gesture of pre

nd ends near the anus, and in front of it. The penis is slender in ruminants, and in wild boar; thick and round in solipedes, elephant, lamentin (sea-cow, manatee); thick and conic in the dolphin, cylindrical in rodents and primates. The gland, which t

one sometimes finds a trace of it in the form of a slender prismatic cartilage. In the enormous penis of the whale it resembles a bell-clapper. The penial bone diminishes the erectile capacity of the prong in stopping the development of the hollow chambers, but it assures the rigidity of the member, obtained in the other penial type by the inflow of blood which causes the swelling. Man ought to have the penial bone; he has lost i

clearly affirms the parallelism of these two organs, whereof one serves only for pleasure, after having been, perhaps in a long distant era, when man romped among marine invertebrates, a real instrument of fecundation. The greater labia, limiting the general orifice of the vulva, exist only in woman and, less markedly, in the female orang-outang. Circular in rodents, transversal in the unique case of the hyena, a heteroclite animal, the vulva is longitudinal in all other mammifers. Completely
