220 DISEASES OF THE DOMESTIC ANIMALS 



the rectum after the bowel has been cleansed by enema. A solution 

 containing gelatin to the amount of 6 per cent., and calcium chloride 

 i per cent., is thus given to horses (in a dose of one pint) at the 

 body temperature. Or gelatin may be given in solution ad libitum 

 by the mouth in which calcium chloride is dissolved (calcium 

 chloride §ss at dose thrice daily) . Turpentine is the most success- 

 ful of the hemostatics and is administered (with one pint of milk) 

 in ounce doses thrice daily to prevent hemorrhages from mucous 

 membranes. In case this is not successful, adrenalin has of late 

 been employed and there have been favorable reports upon its use in 

 purpura hemorrhagica in the human. Four drams (i-iooo adren- 

 alin solution) may be given in a pint of water by the mouth to the 

 horse. 



Collargol is indicated when purpura follows infections and it 

 is best given intravenously (3i in 5 per cent, aqueous solution), or, 

 less effectively, per rectum. Antistreptococcic serum is indicated in 

 streptococcic infection and also in other infections to stimulate 

 phagocytosis. Good results have been reported from its use in 

 veterinary practice; the dose is 20 to 50 c.c, and both it and col- 

 largol may be repeated once or more at intervals of twelve hours, if 

 improvement does not follow the first dose. 



But of chief value in this disease are good hygiene and food. 

 An airy, light, dry and warm box-stall, and a ration of oats, roots, 

 green food, hay and bran mashes, with milk and eggs if there is 

 anorexia, are most serviceable. Mild laxatives only, as 1-2 pints 

 of linseed oil, are permissible. During convalesence arsenous acid 

 (gr. iii), iron (ferrous sulphate, 3i), and bitters (powdered nux 

 vomica, 5i) should be placed on the food thrice daily. Swelling 

 about the head and nostrils may be reduced by constant bathing with 

 cold water. The appearance of sores, sloughing and ulcers demands 

 ordinary surgical treatment. If the breathing becomes embarrassed 

 tracheotomy is indicated. No halter or harness should be permitted 

 on the animal for fear of pressure necrosis. The swellings of the
