INFLAMMATION OF THE LUNGS. 149 



the consequences. Patience must be called into play 

 with this assurance, that as his condition improves with 

 good grooming and gentle exercise, so will his powers 

 of respiration increase in due ratio. Sudden changes, 

 both in diet and atmosphere, must be carefully avoided 

 ever afterwards. 



EOAEING. 



Roaring may be the consequence of one or all of the 

 above-named diseases, or it may arise from causes un- 

 connected with them. Its existence is most difficult 

 to ascertain in slight cases, and the most experienced 

 are very frequently misled. 



Most of the low class of dealers and grooms give 

 horses several sharp and severe digs or blows in the 

 side, or cough them by squeezing the windpipe ; and if 

 the horse grunt or wheeze he is at once pronounced to 

 be a ' piper,' ( roarer,' ( whistler,' or ( grunter,' accord- 

 ing to the judgment of the faculty, who thereupon 

 looks knowing, alters the position of his hat, and struts 

 off to perform on as many other unlucky brutes as 

 happen to come within his unmannerly inspection. 



In this way many horses are rejected as unsound 

 which are perfectly sound, and many that are unsound 

 are passed as sound. 



The only way of judging accurately as to whether the 

 horse really roars, is to take him to a ploughed field, and 

 have him cantered round it until he blows freely, when, 

 if there be any obstruction in the organs of respiration, 

 it will be easily detected by any experienced man.
