186 THEORY AND PRACTICE 



Give three dram doses every hour night and day for ten to fifteen 

 days in order to get the desired effect. The best treatment known 

 is salicylate alkaloid of oil of wintergreen (aspirin), but this is 

 very expensive. The human dose is 'five grains every four hours. 



Other salines are nitrate of potash, one dram three times a 

 day, sulphate of magnesium and all of the laxative salts, iodide 

 of potash, vegetable alteratives, etc. 



The following is good treatment:

Sodii Salicyl ounce vi 



Fl. Ex. Colcliici ounce ij 



Aqua qs. ad pint ij 



M. Sig. — 2 ounces every 4 hours night and day. 



The first remedy you adopt should be used for about ten 

 days and then switch to some other. An acute case seems to run 

 a course of about six weeks. If you have been using the pre- 

 scription given above then change to sulphate of magnesium. 



It is useless to apply stimulating liniments. An application 

 of chloroform for a few minutes, which is allowed to evaporate., 

 will allay the pain. The following is a good liniment: 



Tr, Arnica 

 Tr. Aconite 



Tr. Opii aa ounce j 



Chloroform dram j

In all acute cases of rheumatic lameness and swelling a fly 

 blister is very beneficial. 



LYMPHANGITIS. 



This is an inflammation of the lymphatic ducts. Lymphadenitis 

 is inflammation of the lymphatic glands. There are four forms 

 of lymphangitis, plethoric, anaemic, mycotic or epizootic and 

 septic. The acute plethoric form, develops suddenly in horses 

 that are plethoric and working every day, but laid off for a 

 holiday or a Sunday. The plethoric condition of the horse 

 while at rest is the etiological factor in the case. It may attack 

 any part of the body but generally one of the hind legs. It is 

 usually found in the morning after a day of rest, such as Mon-
