SYSTEMATIC ANALYSIS OP APPARATUS. 117 



Lieberkiihns, after their discoverers, which supply a 

 fluid that assists in changing the starch into sugar. 



434. To STILL FURTHER ASSIST in the process of 

 separating some of the nutritious substances and fitting 

 them to enter the Blood, the Second Stomach is furnished 

 with another very large Gland, the Liver and its accom- 

 panying Gall-bladder, that pour their fluids, Bile and 

 Gall, through a small tube, into the Second Stomach near 

 the orifice of the Pancreatic Duct. (See 20, Fig. 100.) 



435. THUS THE SECOND STOMACH, or small Intes- 

 tinal Canal, is supplied with all required fluids, and being 

 long and with a curious arrangement for increasing the 

 extent of its inner surface, is admirably adapted' to keep 

 the food warm and retain it until it is all dissolved and 

 prepared to enter the Blood, or else, worthless, is only fit 

 to be discharged into the Colon. 



Fig. 103 shows at 1 how the FIG. 103. 



inner surface of the Second Stom- 

 ach is increased by folds, as they 

 are called, of the inner surface or 

 mucous membrane of the canal. 

 4 indicates the sinewy or fibrous 

 structure which is around the 

 tubes, and connects with the se- 

 rous or outer surface, or of the 

 canal, and also the orifices 3, and 

 the tubes 2 of the tubular or Lie- 

 berkiihns glands. 



436. THE COLON is NEEDED as a portable reservoir 

 to receive the waste from digestion and the substances 

 eliminated from the Blood in the various parts of the 

 Digestory Canal and its dependencies. 



437. Inf. THE DIGESTORY APPARATUS must be 

 Modificatory as well as Eliminatory, since the removal 

 of the various fluids mentioned must have an essential 

 influence in modifying the Blood. 



438. To SUM UP THE ORGANS NEEDED IN DIGES- 

 TION: There are three pouches or receptacles for the
