2173. And in this is the sexual apparatus distinguished from them, namely, that it expels the products of _all_ systems, the products of the whole organism, or the organism itself. In the semen the whole male body with all its parts transudes, or passes over in a fluid state, into the female parts; in a child, the female together with the male body, passes over--formed or fashioned into the world. 2174. The sexual intestine must therefore be expulsive also. It is that which conducts the intestinal juice and the refuse of the aliment out of the body. 2175. The evacuating or efferent intestine is the large intestine. It is consequently the _Sexual intestine_. 2176. The large intestine is related to the abdominal or small intestine, exactly like the urinary cyst is to the kidney, and this to the vascular system. The small intestine passes therefore by perforation into the large, not the latter into the former. The small enters by perforating the large intestine, and therein evacuates its alimentary residue, as into a special-cyst, that has nothing to do with the intestinal system. The large intestine is the _excrement_-cyst, just as that which has been called bladder is the _urinary_ cyst. 2177. The large intestine no longer digests, but only receives what is left from the process of digestion and expels or casts it out. 2178. The large intestine begins with a cæcal extremity, or with an obtuse cyst, and opens into the anus, exactly like the original animal cyst, the polyp. The blind extremity is called cæcum. With this the small intestine communicates by perforating it at an acute angle, and that indeed in a direction which runs towards the obtuse cystiform extremity; so that both intestines lie in mutual juxtaposition like a fork, whereof the pharynx and the rectum are the two prongs, while the cæcum is the handle. 2179. The two intestines are consequently by no means correlated. In the perfect animal there are two intestinal systems thoroughly distinct from each other; two intestines, which belong to two different animals, the sexual and encephalic animal, or the plant and the animal. The genesis of the large intestine and all its relations, which are principally seen in the cæcum and rectum, plead for this philosophical derivation of the two intestines. 2180. The rectum appertains wholly and entirely to the sexual system, and especially to the uterus. It is devoid of mesentery, and supplied by special vessels; it stands in most obvious sympathy with the uterus, with its diseases, and with menstruation. Even hemorrhoids are a sexual disease, a disease of the _sexual_ intestine. 2181. The anus is thus the intestinal mouth of the sexual animal. In the lowest organized animals, the oviducts seminal and urinary ducts together run into it, as into a proper mouth. The anus is a true oral cavity in the fishes, reptiles, and even in the whale.
