2327. The ova correspond, as being an object of the semen, to the object of the saliva, which is the food or aliment. The saliva imparts to the bole or mouthful of food its first animal signification; it renders it for the first time capable of passing over into animal organs; it impregnates the morsel. The semen renders the ovum capable of effecting the transition into an animal; it spits upon the ovum.
2328. Impregnation is a process of smearing with saliva, conception a process of deglutition.
2329. Pregnancy is a process of digestion and formation of blood.
2330. If the internal sexual parts denote the internal visceral parts of the mouth, so must the external parts of the one correspond to the external of the other. The labia pudendi correspond to the lips, and the clitoris to the tongue, which is more perfectly represented in the penis. Both tongue and penis consist of two halves; in cases where the former is fissured or divided, the latter is so also, as in the Serpents and Lizards. In many animals, as the dogs and other Mammalia, there is likewise a bone in the penis, which corresponds to the os hyoides or linguale. The salivary ducts have combined with the penis; or, taken in a more strict sense, it may be said, that in the penis the tongue has coalesced with the oral cavity, so that both form a canal,—that of the penis, into which the salivary ducts (vesiculæ seminales) open.
2331. The sexual passion or venereal desire is a gustatory process of the sexual animal, the copulation being at one and the same time a matter both of taste and deglutition.
3. Germ or Embryo.
2332. In the embryo the whole animal already resides in miniature, as does the plant in its seed.
2333. The embryonic intestine is the vitellus or yelk.
