THE DRY OR CHRONIC COUGH. 



This is to be considered as a violent effort of 

 the diaphragm, intercostal, and abdominal muscles, 

 arising from irritation of the mucous membrane 

 of the windpipe. The dry or chronic cough, in 

 general, proceeds from colds injudiciously treated, 

 by which the inflammation passes into a chronic or 

 less active state. (See Inflammation.) The secretion 

 of mucus from that membrane becoming altered in 

 its quality, as when free from inflammation, proves 

 a source of irritation which induces coughing. 



Chronic cough sometimes arises from the irrita- 

 tion of worms in the stomach or intestines, and 

 then requires the remedies recommended for worms. 

 Horses that have glanders, thick or broken wind, 

 ^c. are also subject to this cough.
