CHAPTER V. 



Hnatomical Structure of tbc Sbeep. 



We shall not enter deeply into a consideration of the 

 anatomy of the sheep, believing that the technical terms, while 

 very necessary for the use of scientific men, would only tend to 

 confuse the general reader. "VVe will endeavor to simply ex- 

 plain the general structure and internal organs and their uses, 

 so that when describing symptoms of diseases, and after-death 

 appearences, the parts mentioned can be readily understood. 



We find that the sheep, so far as its general make-up is 

 concerned, resembles the ox very closely. The animal body is 

 an aggregation of separate cells, each endowed with life and 

 having a certain function to perform. The general make up of 

 an animal is called tissue. Tissue of an animal body is a collec- 

 tion of cells, together with their formed material, which is char- 

 acterized by a special function. The formed material is that 

 which surrounds the cells and is not vital in its properties. 



The animal body is composed of solids and fluids. The 

 solids are the muscular, nervous, epithelial and connective 

 tissues. They may be said to enter into 'the conformation of 

 the solids. There are, however, a few special tissues which it will 

 not be worth our while to consider in this work. 



Epithelial cells are those having the special function of 

 protecting the organs underlying them, they also have the func- 

 tion of secretion and enter into nerve construction. They are 

 always found covering the surface of the body, and the interior 

 of all cavities having communication with the exterior of the 

 system. Connective tissue is a collection of cells with their
