dition falls off, the malady always increases, and is apt to degenerate into 

 broken wind. 



When, however, this afEection accompanies, or rather is the result of 

 serious derangement of the pulmonary system, such as broken wind, it is 

 obviously incurable, because the cause from which it proceeds is incur- 

 able. 



SOEE THROAT. 



Synonyms. — Laryngitis; Pharyngitis; Angina, 



Definition. — Inflammation of the lining membrane of the pnarynx 

 and larynx, not often fatal, but nevertheless a not unimportant disease, 

 some-times killing quickly by suffocation, in spite of all efforts to afford 

 relief. 



Etiology. — Pharyngitis and Laryngitis are due to the same causes 

 as common cold. 



Symptoms. — The earliest symptoms are cough and difficulty of 

 swallowing. There is generally a discharge from the nose, even in the 

 earliest stages. The mouth is hot, and the horse is disinclined to eat; or 

 perhaps *' quids" his hay, i.e., lets the masticated hay fall out of his 

 mouth. He only sips his water, or takes it by small mouthf uls and swal-

 order to produce an amount of saliva which may shield the irritated 

 membrane during its passage to the stomach. Hence we find much 

 slobbering from the mouth, and frequently, in bad cases, when the ani- 

 mal drinks, a portion of the fluid comes back through the nostrils, and 

 occasionally part of the food is returned in the same way. A short 

 cough frequently accompanies each inspiration. 



The pulse is quick and the respiration somewhat hurried. If the 

 disease be not checked, the cough will become very hard and harassing, 

 and we may expect fever to follow. Attention should not be diverted, 

 however, to the fever from the real disease. The fever will subside as 

 soon as the irritation which causes it is removed. 



There is sometimes a slight enlargement, which may be seen exter- 

 nally, over the upper end of the windpipe. Any attempt to handle the 

 throat is violently resisted. In severe cases the breathing is often ac-
