118 THE ORANGE COUNTY 



the most prompt and fearless and decisive measures; the 

 lancet should be freely used. Counter-irritants should follow 

 as soon as the violence of the disease is in the slighest degree 

 abated; sedatives must succeed to them; and fortunate will 

 he be who often saves his patient after all the decisive symp- 

 toms of pneumonia are once developed. 



Among the consequences of these severe affections of the 

 lungs, are 



Chronic Cough, 



not always much diminishing the usefulness of the horse, but 

 strangely aggravated at times by any fresh accession of 

 catarrh, and too often degenerating into 



Thick Wind, 



which always materially interferes with the speed of the horse, 

 and in a great proportion of cases terminates in broken wind. 

 It is rare, indeed, that either of these diseases admits of cure. 

 That obstruction in some part of the respiratory canal, which 

 varies in almost every horse, and produces the peculiar 

 sound termed roaring, is also rarely removed. Hearing is a 

 malady of such frequent occurrence and such disastrous con- 

 sequences, that it will be found more discursively treated 

 upon in the concluding pages. 



Glanders, 



the most destructive of all diseases to which the horse is ex- 

 posed, is the consequence of breathing the atmosphere of foul and 

 vitiated stables. It is the winding up of almost every other 

 disease, and in every stage it is most contagious. Its most 

 prominent symptoms are a small but constant discharge of 

 sticky matter from the nose; an enlargement and induration 

 of the glands beneath and within the lower jaw, on one or 

 both sides; and before the termination of the disease chan- 

 crous inflammation of the nostril on the same side with the 

 enlarged gland. Its contagiousness should never be forgot- 

 ten, for if a glandered horse is once introduced into a stable, 

 almost every inhabitant of that stable will sooner or later 

 become infected and die. 



The Urinary and Genital Organs 



are also lined by mucous membranes. The horse is subject
