120 DISEASES OY THE LUNGS. 



it may last weeks or months : it has been known in young 

 animals to continue years. 



During the second stage j — 1, the case more or less develops 

 itself. The respiration, though it may not be perceptibly 

 disturbed at the flanks, will probably be found to be 

 slightly disordered by narrowly observing the nostrils; and 

 if they do not afford us the required information, our ear, 

 applied to the breast or side, may. 2. By this, or with our 

 hand, we may also discover tenderness about the sides. The 

 pulse will be found quicker than it ought to be. 3. A short 

 dry cough is heard now and then. The appetite is fas- 

 tidious : at one time very good ; at another, indifferent ;

 troublesome cough, and the occasional coughing-up of the 

 expectorated matters through the nose and mouth ; by great 

 emaciation and debility ; by partial separation of the coat, so

 dropsical swellings perhaps of the legs, sheath, and belly ; by 

 complete loss of appetite ; by general irritability, and a truly 

 distressing, haggard sort of expression of countenance; by 

 an irritable state of the bowels and great proneness to 

 diarrhoea, which, once excited, in this state of extreme 

 debility, is likely to carry our patient off. 



The post-mortem appearances, as well as the symptoms, 

 are liable to a great deal of variation. In some cases,
