DISEASES OF THE THROAT. 283 



and scientific practitioners, some of whom have a specific 

 name for the disease of every little organ in the throat. As 

 our work is designed for the farmer, we prefer to adopt this 

 name instead of the others. This whole class of diseases, in 

 the causes, development, and treatment of each, are so much 

 alike amid all their slight diversities of location, that this can 

 be done without any serious confusion or lack of precision. 



While engaged in the preparation of the pages for one of 

 the preceding chapters, we saw a case of this kind on Wal- 

 nut Hills, near Cincinnati. It was swelled throat from the 

 effects of cold and inflammation of the glands. 



These inflammations often become chronic, and not a few 

 of the obstinate coughs that so much trouble both the horse 

 and his owner have their origin right here. 



Laryngitis, or inflammation of the larynx, is the most 

 common disease, which we may consider under the general 

 name at the head of this section. Mr. Youatt gives this de- 

 scription of it : 



"Its approach is often insidious, scarcel}^ to be distin- 

 guished from catarrh, except by being attended with more 

 soreness of throat, and less enlargement of the parotid 

 glands. There are, also, more decided and violent parox- 

 ysms of coughing than in common catarrh, attended by a 

 gurgling noise, which may be heard at a little distance from 

 the horse, and which, by auscultation, is decidedly referable 

 to the larynx. The breathing is shorter and quicker, and 

 evidently more painful than catarrh ; the membrane of the 

 nose is redder ; it is of a deep modena color ; and the horse 

 shrinks and exhibits great pain when the larynx is pressed 

 upon. The paroxysms of coughing become more frequent and 

 violent, and the animal appears, at times, almost suffocated. 



"As the soreness of the throat proceeds, the head of the 

 animal is projected, and the neck has a peculiar stiffness. 

 There is, also, much difliculty of swallowing. Considerable 

 swelling of the larynx and the pharynx ensue, and also of 

 the parotid, sublingual, and submaxillary glands. As the in- 

 flammation increases, the cough becomes hoarse and feeble,
