by a loud wheezing noise, which is particularly observable 

 during exertion. Any sudden movement, a sharp trot, or 

 even an unexpected blow upon the ribs, produces a short, 

 dry, loud cough. Thick wind may be palliated, and occa- 

 sionally cured, by sedatives. For this purpose take — 



Nitre - - -^ 



Opium - - V- One drachm each. 



Camphor - - ) 



This dose may be given once or twice a day before the 

 animal is fed, and continue for two or three days. 



Another excellent preparation for the same purpose is the 

 following : 



( Nitre - - - | One drachm 



For one ball -j Extract of belladona ) each. 



( Arsenic - - . Eight grains. 



This may be given for seven or eight days. The com- 

 plaint may also be greatly mitigated by using easy digestible 

 nutritive food of small bulk, supplying one or two pounds 

 daily of linseed cake. Beside these, feed regularly and often. 

 Limit as much as possible the quantity of water — small 

 drinks, but often, if required. And lastly, always allow an 

 hour to elapse between feeding and work. 



BROKEN WIND, HEAVES, PULMONARY EMPHYSEMA, &c. 



These names stand for a structural disease which is seen 

 by one inspiratory followed by two expiratory acts while 

 breathing. There is also a hollow, muffled cough, which is 

 easily detected by pressure on the larynx ; the nostrils are 

 unnaturally dilated, and the flanks constantly agitated; the 

 ribs and abdominal muscles are called into action to assist 

 in the double expiration. This disease results from rupture 

 of the cells or lobes of the lungs, and is generally produced 

 by feeding on coarse unnutritious food in large quantities. 

 When the animal is put to work in this state the pressure 

 against the lungs ruptures those parts. It is sometimes 

 hereditary. 



No cure recommended.
