26. The average size of the stomach differs with the 

 habits of men and the kind of food which they consume. 

 It is larger in those who live on vegetable focd, which con- 

 tains less nutriment in the same bulk, than in those who .live 

 on animal food, which is richer and more nutritious, and 

 therefore occupies less space. This difference is more 

 marked between the size of the stomach of the carnivorous, 

 or flesh-eating animals, and that of the herbivorous, or vege- 

 table-eating animals. The hare has a much larger stomach 

 than the greyhound. The stomach of the cow is large, and 

 her alimentary canal is twenty-four times the length of her 

 body ; whereas, in some of the carnivorous animals, this 

 canal is not much longer than their bodies are. Men who 

 are in the habit of gormandizing have very great stomachs.
