CATAERH AND LARYNGITIS. 



CATARRH. 



Synonyms. — Common cold, coryza, a defluxion or rumiing at 

 the nose, and is witnessed in the horse, ox, sheep, and other 

 animals. 



Symptoms. — Catarrh is indicated by sneezing, running from 

 the eyes, redness and dryness of the Schneiderian membrane, 

 succeeded by a discharge, at first thin and colourless, which 

 soon, however, becomes turbid, yellowish- white, and profuse. 

 It is associated with a varying degree of fever, dulness, and 

 debility. 



Causes. — Alternations of temperature, hot, ill- ventilated stables, 

 exposure to wet and cold, A strong predisposition to cold exists 

 during the process of changing the coat. Young animals, more 

 especially if newly brought into warm stables, are pre-eminently 

 liable to suffer. In some instances it is complicated with laryn- 

 gitis, and in all cases, if the animal be neglected, the catarrhal 

 inflammation is apt to spread from the nose over the whole 

 surface of the respiratory mucous membrane. 



Treatment. — This is a very simple matter if adopted in time, 

 and consists in placing the aninaal in a well-ventilated loose box, 

 clothing the body if the weather be cold, feeding upon bran 

 mashes, boiled linseed, and a small quantity of good hay for a 

 few days. 



In the early stages the nasal irritation will be much relieved
