LESSON 52.] NUTRITION IN THE MAMMALIA. 185 



The large intestine (colon) of the Feline animals agrees in gen- 

 eral particulars with the characteristics usually exhibited in the ani- 

 mal kingdom, with respect to the great resemblance it uniformly

bears to the structure of the stomach. A figure (295) of this part 

 of the intestine of a Cat is given. 



If the papillary surface be carefully dissected from a well inject- 

 ed intestine, the sub-mucous tissue will be found to present a beauti- 

 ful view of the vessels which supply blood to the villi, and of those 

 which are employed to effect its return in other words, arteries and 

 veins. 



As these vessels end or commence in capillaries, they are neces-

sarily minute ; but in the layer immediately beneath, the larger 

 vessels, in connection with this particular plexus, are found. 



A figure of this structure, from the small intestine of the Lion, 

 is given (Fig. 296), which shows all that has been described. 



802. In the Canine animals (Dogs), many of the tissues differ 

 greatly from those of the Feline ; the tongue, for example, is re- 

 markable for its extreme softness and ductility. Possessing villi of 

 the same denomination, in these animals they appear to be endowed 

 with exquisite sensibility, at least the distribution of the gustatory 

 nerves (nerves of taste) would lead to such conclusion.
