the vegetative systems, but they take place in the reverse 

 direction. The latter convey inwards, the former out- 

 wards. The kidneys are a reversed or evacuating lung, 

 an excrement-forming liver ; the urinary bladder is an 

 exspirant, a trachea containing refuse matter ; the urethra 

 is a glottis reversed ; their diseases are therefore similar. 

 They thus expel products of the individual respiratory 

 system. 



2173. And in this is the sexual apparatus distin- 

 guished 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 ex- 

 pulsive 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 bladder 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 per- 

 forating the large intestine, and therein evacuates its 

 alimentary residue, as into a special-cyst, that has no- 

 thing to do with the intestinal system. The large 

 intestine is the excrement-cysi, just as that which has 

 been called bladder is the urinary bladder. 



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 csecal extre- 

 mity, or with an obtuse cyst, and opens into the anus, 

 exactly like the original animal cyst, the polyp. The 

 blind extremity is called caecum. With this the small 

 intestine communicates by perforating it at an acute
