VI. Quinsy. 



Causes. — Sometimes the inflammation in the throat in laryngitis is so 

 great and deep seated that abscesses f onn in the throat, producing quinsy. 

 It is caused by the same agents as hiryngitis, and is always more pro- 

 longed in duratiou than simple sore throat. 



How to know it. — It may start with all the symptoms of laryngitis 

 but will not yield to treatment at first. The throat gets sorer and sorer 

 from day to day, till suddenlj'^ the abscess bursts, and a tremendous 

 flow of pus comes from the nostril, and the animal Avill be relieved at 

 once. Quinsy lasts from one to three or four weeks, and is very apt to 

 be followed by roaring or whistling. 



What to do. — Apply the same treatment as prescribed for laryngitis. 

 Continue the linseed poultices right through ; apply them so as to cover 

 the throat nearly to the ears, and keep them quite soft. 



Vn. Bronchitis. 



The bronchial tubes are the two branches of the trachea or wind pipe ; 

 they lead to the lungs. Inflammation of these branches, and also of the 

 lining of the tubes as they ramify through the lungs, is known as bron- 

 chitis. 



A Fir SUBJECT FOR FOUNDER OR BRONCHITIS. 



Causes. — The same exposures that cause catarrh and sore throat are 

 prolific agents in producing this disease. And there is a very great ten- 

 dency in the horse to inflammations of the upper air passages which run 

 down upon the lungs, so much so that many cases of catarrh and larjmgi- 

 tis terminate in bronchitis and pneumonia.
