OAK BARK. 253 



benefit from it, it will have to be given for a week or 

 two, if the beast has not got well by that time. In the 

 use of strychnine, care and good judgment must be exer- 

 cised, for it must be remembered that ^however useful a 

 drug, or medicine may be, is no argument that it can not 

 be abused. Strychnine should be administered in feed, 

 if the animal will eat it, if not give it in gruel in the 

 form of a drench. Twelve grains is the dose required 

 to kill a full grown horse. 



Arsenite of Strychnia is recommended by the French 

 veterinary surgeons, in nasal discharges, but with what 

 effect is not stated. If it does not cure, as I suppose 

 it does not, it only serves to show to my mind how utterly 

 ignorant veterinary surgeons are in regard to the true 

 pathalogy of those discharges, supposed to be glanders. 

 Mr. Gamgee, on the International Veterinary Congress, 

 held at Hamburg, says when the subject of glanders was 

 mentioned, no one responded. Why ? certainly not that 

 they knew all about it, no, the contrary is the case, for 

 they knew nothing at all about its nature, and hence we 

 have the French using a drug the least of all likely to 

 change, arrest, or cure the disease. Prussian blue is 

 said to contain ten per cent of strychnia, some packa- 

 ges contain as high as sixty grains. 



Oak Bark. — Qiiercus Cortex. — This is a good astrin- 

 , gent for outward use, or to sores which discharge a good 

 deal. The bark is boiled, half an ounce to a pint of wa- 

 ter. This decoction is an excellent remedy for drying 

 up the moisture of greasy heels, so troublesome in horses. 

 In diarrhoea in calves, given in four drachm doses, much 

 good will follow its use. 



Oils. — There are two varieties of oils used in medi- 

 cine — fixed and volatile.
