Sheep are not exempt from diseases of an inflammatory charac- 

 ter, as was and is supposed, but we know less about them than about 

 the same diseases in other animals. They 

 are very liable to diseases affecting the di- 

 gestive organs. Sheep readily succumb to 

 ailments in which debility and the exhaus- 

 tive powers of parasites are main factors. 

 Parasites ahd invisible germs may be said 

 to constitute their greatest enemies. From 

 the fact that they gather together in flocks, 

 infectious and contagious diseases have per- 

 haps freer run among them than among any 

 other domestic animals. The structure ^of 

 the foot is about that of other ruminants and 

 of the hog, yet it is subject to diseases from 

 which those animals are free, though in this 

 respect sheep-raisers find fewer annoyances 

 in this country than in Europe. 



Ordinary diseases in sheep are occasioned 

 mainly by some of the following causes: 

 Overfeeding, underfeeding,, irregularity of 

 feeding, impure and damp air, impure water, 

 worrying, fatiguing or heating in driving, 

 and sudden changes of temperature. 



DISEASES 



OF THE RESPIRATORY 

 ORGANS. 



Catarrh is inflammation of the mucous 

 membrane of the nasal cavities and the 

 sinuses of the head. When long continued, 

 the windpipe and the lungs may become 

 involved. - Overdriving by men or dogs, 

 chilling rain-storms, damp nights, and 

 blows on the head are among the common 

 causes. Fresh air, ample ventilation, d?y 

 bedding, and warm mucilaginous drinks, 

 such as oatmeal gruel, may be profitably em- 

 ployed. If fever ensues, and the nose and 

 mouth are dry and hot, the following may 

 be given : —
