Definition. — A chronic disease of the breathing organs, 

 without inflammation, characterised by a peculiar breathing, 

 the breath being drawn in with ease, but breathed out by 

 two distinct efforts. There is always a peculiar cough of a 

 hollow muffled sound, easily produced at any time by pres- 

 sure on the upper part of the windpipe ; and nearly always 

 there is indigestion with flatulence. 



Causes. — The immediate cause is rupture of the small 

 cells in the lungs, so that the animal cannot expel the air he 

 has drawn in without an extra and double effort. This 

 rupture is brought about by putting the horse to hard work 

 with his stomach full of coarse and undigested food ; or by 

 hereditary predisposition. 



S3^ptoms. — Usually the character of the expirations 

 above noted and the cough leave no doubt of the disease. 

 On percussion, the chest is found to be more resonant than 

 natural ; and on listening with the ear to the chest, a rustling 

 sound is heard, denoting the presence of air in the lung 

 tissue. The symptoms are always more severe when the 

 animal has a full stomach. The animal usually is unthrifty, 

 dyspeptic and with a harsh dry coat. 



Treatment. — A cure is impossible ; but great relief may 

 be had by feeding the horse on light nutritious food in mod- 

 erate quantities, and by improving his digestion by alkalies, 

 acids or tonics. A purgative should occasionally be admin- 

 istered and the bowels kept regular. 



A celebrated recipe of the late Professor Dick in this 

 disease was : —
