For simple cases tlie foregoing is all that is required, but if the appe- 

 tite is lost, aud the animal appears debilitated and dull, give 3 ounces 

 of the solution of acetate of ammonia and 2 drams of powdered chlo- 

 rate of potassium diluted with a pint of water three times a day as a 

 drench. Be careful when giving the drench; do not pound the horse 

 on the gullet to make him swallow; be x)atient, and take time, and do 

 it right. 



If the weather be cold, blanket the animal and keep him in a com- 

 fortable stall. If the throat is sore, treat as advised for that ailment, 

 to be described hereafter. 



When the inflammatory symptoms subside and the appetite is not 

 regained, give 2 ounces each of the tincture of gentian and spirits of 

 nitrous ether in a pint of water, as a drench, every night and morning 

 for several days. If, after ten days or two weeks, the discharge from 

 the nostrils continues, give 1 dram of i)owdered sulphate of iron three 

 times a day. This may be mixed with bran and oats, if the horse 

 will eat it, but if he will not eat the food with the iron in it, give the 

 iron as a drench, dissolved in a pint of water. 



It may be objected that rather more space than necessary is devoted 

 to this simple affection ; but when it is known that there is a ten- 

 dency to the extension of the trouble, and that serious complications 

 may ensue, the fact should be appreciated that there is every reason 

 why the common cold should be thoroughly understood and intelli- 

 gently treated in order to i^revent the more dangerous diseases. 



CHRONIC CATARRH — XASAL GLEET. 



This is a subacute or chronic inflammation of some part of the 

 membrane affected in common cold, the disease just described. It is 

 manifested by a persistent discharge of a thick, white, or yellowish- 

 white matter from one or both nostrils. The sinuses of the head are 

 the usual seat of the disease. The commonest cause is a neglected 

 or badly treated cold, and it usually follows those cases where the 

 horse has suffered exposure, been overworked, or has not received 

 proper food, and, as a consequence, has become debilitated. 



Other but less frequent causes for this affection are : Fractures of 

 the bones that involve the membrane of the sinuses; and even blows 

 on the head over the sinuses, of sufficient force to rujiture blood- 

 vessels within. The blood thus escaping into the sinus acts as an 

 irritant, and sets up an inflamination. Diseased teeth often involve 

 a sinus, and cause a fetid discharge from the nostril. Violent cough- 

 ing is said to have forced particles of food into the sinus, which acted 

 as a cause of the disease. Tumors growing in the sinuses are known 

 to have caused it. It is also attributed to matter from disease of 

 the turbinated bones. Absorption of the bones forming the walls 

 of the sinuses has been caused by the pressure of pus collecting in 

 them, and by tumors filling up the cavity.
