PART IV. 



DISEASES AND TREATMENT OF SHEEP AND 

 PIGS. 



SHEEP. 



SHEEP belong to that class of animals called Rumin- 

 ants — those that chew their cud. The act known as 

 Rumination is fully described in Part III. 

 The skeleton of the sheep is built on the same principle 

 as that of the ox. It is much smaller, but the bones, joints, 

 etc., are so similar that it is unnecessary to present them here. 

 The skin differs from that of the ox in the matter of 

 being covered with wool instead of hair. It also contains 

 many small glands for the secretion of oil with which to 

 lubricate and soften the wool.
