122 DISEASES OF THE HORSE. 



2 ounces; rectified spirits, 3 ounces; water, 1 pint. Repeat the dose 

 every four or five hours if it appears to benefit. When the horse is 

 hard to drench, give the following: Pulverized carbonate of am- 

 monia, 3 drams; linseed meal and molasses sufficient to make the 

 whole into a stiif mass; wrap it with a small piece of tissue paper 

 and give as a ball. This ball may be repeated every four or five 

 hours. ^Mien giving the ball care should be taken to prevent its 

 breaking in the mouth, as in case of such accident it will make the 

 mouth sore and prevent the animal from eating. If the bowels are 

 constipated, give enemas of warm water. Do not give purgative 

 medicines. Do not bleed the animal. 



If the animal retains an appetite, a soft diet is preferable, such as 

 scalded oats, bran mashes, and grass, if in season. If he refuses 

 cooked feed, allow in small quantities anything he will eat. Hay, 

 cob corn, oats, bread, apples, and carrots may be tried in turn. 

 Some horses will drink sweet milk when they refuse all other kinds 

 of feed, and especially is this the case if the drinking water is with- 

 held for a while. One or 2 gallons at a time, four or five times a 

 day, will support life. Bear in mind that when the disease is estab- 

 lished recovery can not occur in less than two or three weeks, and 

 more time may be necessary. Good nursing and patience are re- 

 quired. 



When the symptoms have abated and nothing remains of the dis- 

 ease except the cough and a white discharge from the nostrils, all 

 other medicines should be discontinued and a course of tonic treat- 

 ment pursued. Give the following mixture : Reduced iron, 3 ounces ; 

 j)owdered gentian, 8 ounces ; mix well together and divide into sixteen 

 powders. Give a powder every night and morning mixed with bran 

 and oats, if the animal will eat it, or shaken with about a pint of flax- 

 seed tea and administered as a drench. 



If the cough remains after the horse is apparently well, give 1 

 dram of icdid of potassium dissolved in a bucketful of drinking 

 water one hour before each meal for two or three weeks if necessary. 

 Do not put the animal to work too soon after recovery. Allow ample 

 'time to regain strength. This disease is prone to become chronic and 

 may run into an incurable case of thick wind. 



PLEURISY. 



The thoracic cavity is divided into two lateral compartments, each 

 containing one lung and a part of the heart. Each lung has its sepa- 

 rate pleural membrane, or covering. The pleura is the thin, glisten- 

 ing membrane that covers the lung and also completely covers the in- 

 ternal walls of the chest. It is very thin, and to the ordinary ob- 

 server appears to be part of the lung, which, in fact, it is for all
