or secernent, the duodenum, the third or absorbent, the 

 small intestine (jejunum and ileum). 



Pulmonic Intestine. 



2160. All solution is accompanied by oxydation. The 

 gastric juice is in its action an acid. 



2161. The gastric juice obtains its oxygen from the 

 spleen. The spleen is the stomachic lung This is attested 

 by its position and close approximation to the stomach ; 

 by its black, venous, and deoxydized blood, which in 

 certain diseases has been secreted even in the stomach ; 

 by its want of any excretory duct ; by its tissue, which 

 resembles that of the oxydized placenta ; furthermore by 

 the natural character of this function when contrasted 

 with the unnatural quality of other useless functions that 

 have been assigned to it ; and lastly too, by the fact 

 that, without this opinion be admitted, it must remain 

 a superfluous organ, and as regards use, unknown. 

 After a series of years, during which this doctrine has 

 been combated upon all sides, without, however, a single 

 reason, save and except that it was not believed, being 

 advanced by its opponents, I must still persist in the 

 correctness of the above view. 



Vascular Intestine. 



2162. In the duodenum the analysis of the food 

 takes place through the medium of the bile. It is con- 

 sequently the biliary intestine or stomach. 



2163. The biliary intestine does not stand upon a par 

 with the other intestines, but has an equal rank with the 

 stomach. It is therefore not confined within the me- 

 sentery, but can expand itself like the stomach ; it has 

 its vessels and nerves. In it the separation of the chyme 

 into chyle and excrementitious matter takes place. 



2164. What the spleen is for the stomach, that is the 

 liver for the duodenum ; it is the hepatic stomach, and 

 consequently the vascular stomach. 



2165. The liver is the ramification of the intestinal 

 canal along with the whole vascular system.
