Pleuro- Pneumonia, 271 



monia is about, the animal should be separated from the 

 herd, disinfectants used, and a watch kept for the next de- 

 , velopments of the disease. 



These are slight sliivering and staring coat ; some loss of 

 ai^petite; scanty milk ; an occasional dry and hard cough; 

 irregular chewing of the cud ; bowels rather constipated ; 

 urine less than usual, and high or dark in color. 



These insidious symptoms may continue several days 

 without the appearance of others of a more marked charac- 

 ter. Sometimes there is tenderness on pressure between the 

 ribs over the lungs, as evinced by a slight wince or groan. 

 The cough now increases, the breathing is more frequent, 

 and when the animal stands the ellbows are turned out, the 

 nose is extended, the back arched, and the hind legs drawn 

 up under the body. Later on, there is a watery or mattery 

 discharge from the eyes and nose, there is rapid loss of flesh, 

 the animal is hide bound, and there is either obstinate con- 

 stipation or a violent watery diarrhea of fetid matter, which 

 rapidly weakens and destroys life. 



The symptoms on percussing over the lungs are in the 

 earlier stages a clear or resonant sound, which, as the disease 

 advances, gives way to a dull, heavy one. On listening in 

 the first stage, a dry, creaking sound is heard, caused by the 

 inflamed surface of the lung and its covering (the pleura) 

 rubbing against each other. Later, there are irregular whist- 

 ling or rough breathing sounds, easily distinguished from"the 

 sounds caused by the lungs in health. 



The rule is generally positive that where both lungs are 

 affected the animal dies. 



Treatment. — It cannot be said that the medical treatment 

 of pleuro-pneumonia is very satisfactory. Many remedies 

 have been recommended from time to time, but the use of 

 them in practice has not met the expectations created. 



Perhaps the most prudent course is to put the animal in
