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 oeso- 

 phagus and the rectum are the two prongs, while the 

 caecum 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 caecum 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. 



2182. The oesophagus opens into the mouth, and so 

 does the rectum into the anus ; the trachea opens into 

 the mouth, and so does the urethra into the anus ; the 

 salivary ducts open into the mouth, and so into the 

 anus do the oviducts, with the spermatic canals in the 

 lower animals. The rectum moreover lies behind the 

 urinary bladder, like the gullet behind the trachea. 



2183. The sphincter or occlusor muscles of the anus 

 have been formed like the sphincter muscles of the 

 pharynx. The anus is a mouth without a head, and 

 therefore a mouth without lips, or an oesophagus. 



Cephalic Intestine.
