INTRODUCTION. 



Outline of the Stomach of a full-grown Cow. 



[These engravings, illustrative of the comparative 

 sizes of the different stomachal cavities, are copied 

 from original drawings taken from preparations of the 

 stomachs which I made expressly for this purpose.] 



In all herbivorous animals, and especially those of 

 the ruminating kind, the alimentary canal is of an 

 enormous length ; measuring in a full grown ox, as 

 much as sixty yards. The paunch, in such an animal, 

 will hold from fifteen to eighteen gallons.
