PLEURO-PNEUMONIA. 319 



The tongue ultimately swells. Light is lost. The cow 

 obstinately stands in one place, and in one position, and 

 ultimately sinks to die suddenly. 



Such are the main features of this fearful disorder, which, 

 since it has been better understood, has appeared as though 

 it became of a milder character. A beast might, however, 

 during the severest times have two, or even three attacks, 

 and ultimately survive and do well. There is one marked 

 peculiarity about the disease. The cow never entirely loses 

 her milk ; it may be reduced to half a pint, but the half 

 pint is to the last to be obtained. The bowels are always 

 irregular ; but if the disease begin with purging, the case 

 generally terminates the sooner. If the cow be in calf, 

 abortion is a very bad sign ; but should the foetus be re- 

 tained, the youngster will be born with the disease from 

 which his mother has recovered, and he will assuredly die, 

 almost in his birth. 



If the disease be detected in the first stage, should the 

 animal be abroad, let it be brought home, but with the 

 utmost care ; and if at home, let the shed in which it stands 

 be made scrupulously clean. Remove every thing of a 

 dirty, foul, or putrid kind. Scrape and wash the walls. 

 Damp in this disease is not desirable, but it is infinitely less 

 to be dreaded than tainted air. Having made clear the 

 place in which the beast is to reside, let her enter it; 

 though, if the animal be already in the shed, do not remove 

 her ; as the one that stands next to her is not more likely 

 to be taken, although she should die of the complaint ; and 

 cows are proved to pine, and thus aggravate the disorder, 

 when placed by themselves. Withhold all food, even 

 though the animal be inclined to feed, w^hich generally they 

 are not disposed to do. It is not that which goes down 

 the throat that does good, but that which is converted into 

 chyle alone nourishes the system. We should be very glad 

 could food be appropriated, but in this disorder nothing is 

 digested, and whatever is swallowed remains in the rumen 

 to decay. Decaying vegetable matter sets free much gas, 

 and hoven is one of the worst symptoms, especially in the 

 latter stages. Unfortunately, the appetite is often ex- 

 traordinary towards the commencement of this affection, 

 and the consequence is (nothing being digested) a loaded
