§4 THE DISEASES OF THE HORSE. 



tecedent shivering. Auscultation reveals a distinct cooing 

 sort of sound, arising from want of secretion within the 

 tubes. When the secretion returns, and in augmented 

 quantity, the rattle is distinctly heard. 



In catarrhal bronchitis, in addition to most of the above 

 symptoms, the nasal discharge, which at first is but slight 

 and of a watery or muco-watery description, in three or 

 four days becomes of a puro-mucous nature and increased 

 in quantity. The symptoms of catarrh and sore throat 

 gradually abate and merge into that short and laborious 

 breathing which clearly denotes high bronchial and pul- 

 monary irritation. When the horse coughs, which it does 

 more now, an increased discharge is expelled from the 

 nose ; when it hangs its head, the discharge runs out. 



Symptoms of independent (uncomplicated) bronchitis : 

 Sudden illness ; violent blowing and distressful breathing ; 

 sudden and copious mucous discharges from the nose ; 

 may obtain relief at the moment, but there is danger of 

 suffocation, especially if the discharges are frequently re- 

 peated. These sudden and violent attacks usually soften 

 down to ordinary bronchitis, but they sometimes increase 

 in violence and end in pulmonary disease. 



Epizootic symptoms : Exceedingly sore throat and. pro- 

 fuse discharges from nose; sometimes white, sometimes 

 yellow, sometimes even green, according to circumstances. 

 The green tinge arises either from malignancy or green 

 food. Great weakness of loins ; also general weakness ; 

 low febrile irritation. 



Remedy. — Comfortable, cool, well ventilated box; tem- 

 perature 60 to 65° F. Body and limbs clothed. Inhala- 

 tion of watery vapor from steam kettle, a large mash, or 

 bucket of boiling water promotes exudation in dry stage, 

 the inhalation to be medicated, as required, with expec- 

 torants, anodynes, or antiseptics. (See Fig. 14.) Fomen- 

 tations and mustard to throat and sides. Mustard in earlier 

 stages applied for 15 or 20 minutes, washed off, and re-
