2166. Now, as the analysis is the principal function 

 in the whole process of digestion ; so is the liver the 

 chief organ of all digestive organs. 



2167. The liver is the centre, the brain of the diges- 

 tive system, because it is the blossom, the synthesis of 

 the vascular system. From it everything emanates, and 

 upon it everything which concerns digestion, ay, the whole 

 body, retrogressively operates. If the liver suffers or 

 undergoes functional derangement, the whole vascular 

 and tegumentary formation then becomes a liver, as is 

 exemplified in the disease called jaundice. 



2168. The bile effects the analysis or separation 

 through its basic or alkaline character, since it combines 

 with the acids of the chyme, and thereby forms the. 

 excrementitious matter. 



2169. That which mediates between the acid and 

 what is alkaline is the fluid secreted by the pancreatic 

 gland. The pancreatic gland is the ramification of the 

 intestine along with the arterial system. 



Tegumentat Intestine. 



2170. That in the jejunum and ileum or the small 

 intestine proper, and in that alone, absorption and thus 

 the tegumentary function, but nothing else, occurs, is 

 well known. By this absorption the chyle becomes re- 

 moved from the intestine, so that the excrement alone is 

 left. 



b. Sexual Intestine. 



2171. The sexual is pre-eminently that which is ex- 

 secernent or excretive, since one sex strives to redinte- 

 grate itself upon the other, becomes ingestive for the 

 other, but egestive for or in relation to itself. It is 

 therefore an essential property of the sexual parts, that 

 they secrete and excrete. 



2172. Every galvanic system, which has been ad- 

 joined or appended to the sexual parts, is excretive. 

 They are, taken in a rigid sense, the only system of ex- 

 cretion. The co-operative processes of the sex are those of
