THE RESPIRATORY ORGANS 339 



SHEEP. 



552. Sheep are also subject to derangements and diseases of the 

 respiratory organs, similar to those of other domestic animals ; but 

 on account of their fine organization and their open-air life, they are 

 generally too far gone before they are noticed to be ailing and for 

 any successful treatment to be carried out — certain parasitic diseases 

 of the lungs excepted. In stormy wintry weather, when sheep are 

 folded on unsheltered pastures, it is not uncommon to see and hear 

 of large numbers dying of acute congestion and inflammation of the 

 lungs, which, in some districts, rages like an epizootic. When such 

 is the case, the remaining animals should be removed to more shel- 

 tered quarters, and easily digestible and nutritious food should be 

 supplied, such as crushed oats, bran, and cake. Lambs, at times, 

 also die in great numbers from a somewhat similar cause, and must 

 receive similar treatment. 



553. Verminous or Parasitic Bronchitis, or Hoose (Paper 

 Skin). — This is one of the most common maladies seen in lambs, 

 and has already been dealt with (pars. 340 and 341).
