Catarrhal Pharyngitis. 53 



Prevention. Avoid the various thermal, chemical, mechanical, 

 and unhygienic causes already referred to, and the exposure to 

 such infectious diseases as are liable to localize themselves in the 

 throat. 



Treatment. A piece of blanket or sheepskin placed round the 

 throat with the wool turned inward, a moderately warm stall with 

 pure air, and a diet composed of soft, warm or tepid mashes, (all 

 hard or fibrous food, oats, hay, etc. being withheld) are important 

 conditions. 



If ccstiveness exists a dose of Glauber salts for the larger 

 animals, and of jalap for the small, may be useful. Or pilocar- 

 pine or eserine may be given hypodermically. Following this, 

 mild saline diuretics will serve at once to eliminate offensive 

 products of the disease and lower the general temperature. 



The most important resorts however, are the local applications 

 of dilute, acids, astringents and antiseptics to the pharyngeal 

 mucosa, mouth and nostrils. In severe cases benefit may be de- 

 rived from inhalation of water vapor, but this is rendered far 

 more effective by the addition of vinegar, carbolic acid, creolin, 

 camphor, tar, or sulphurous acid. The last may be obtained by 

 the frequent burning of a carefully graduated quantity of sulphur 

 in the stall, the others by mixing them with hot water, saturating 

 cloths hung in the .stall, or sprinkling them on sand laid on the 

 floor. 



Chlorate of potash or borax may be dissolved in the drinking 

 water, care being taken not to exceed the physiological dose. 

 Mercuric chloride (1:2000) may be u.sed to wash the lips and 

 nostrils, but cannot be safely injected into mouth or nose. 

 Powdered alum or tannic acid may be used by insufflation. 



As a mouth wash and general medicament a saturated solution 

 of chlorate of pota.sh in tincture of muriate of iron, diluted by 

 adding thirty drops to the ounce of water, may be given every 

 hour or two. Or a solution of chlorine water diluted so as to be 

 non-irritating, may be substituted with .somewhat less effect. 

 Even a weak solution of hydrochloric acid may be employed. 



Borax may be used in a solution of 2 per cent., or carbolic 

 acid in one of i per cent. , or bisulphite of soda in the proportion 

 of Yz oz. to the pint, or .salicylate of soda ^ oz. to the pint of 

 water. The .same agents may be made into electuaries with
