COUGH GLANDERS. 485 



ment of that inflauimatioii, and yet little expenditure of vital 



power. 



Cough may degenerate into inflammation of the lungs ; or 

 this fearful malady may be developed without a single pre- 

 monitory symptom, and prove fatal in twenty-four, or even in 

 twelve hours. It is mostly characterized by deathly coldness of 

 the extremities, expansion of the nostril, redness of its lining 

 membrane, singularly anxious countenance, constant gazing at 

 the flank, and an unwillingness to move. A successful treat- 

 ment of such a case can be founded only on 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 slightest degree abated; sedatives must 

 succeed to them ; and fortunate will he be who often saves 

 his patient after all the decisive symptoms of pneumonia are 

 once developed. 



Among the consequences of these severe afiections of the 

 lungs, are chronic cough, not always much diminishing the use- 

 fulness 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 Math 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. Koaring is a 

 malady of such frequent occurrence and such disastrous conse- 

 quences that it will be found more discursively treated upon in 

 the concluding pages. 



Glanders, the most destructive of all the diseases to which 

 the horse is exposed, is the consequence of breathing the atmo- 

 sphere of foul and vitiated stables. It is the winding up of 

 almost every other disease, and in every stage it is most conta- 

 gious. 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, 

 chancrous inflammation of the nostril on the same side with the 

 enlarged gland. Its contagiousness should never be forgotten,
