358 DISEASES OF DOGS : THE EAR. 



styptic tincture will be found very efficacious in 

 curing canker on the outside of the ear, but some- 

 times it will be requisite, in order to expedite the 

 cure, to physic the dog once or twice. 



(RECIPE, No. 44.) 

 Styptic Tincture. 



Take — Egyptiacum, one ounce ; 



Oil of vitriol, two drachms ; 



Nitrous acid, two drachms ; 



Spirits of turpentine, one ounce; 



Rectified spirits of wine, two ounces : 



Mix the egyptiacum with a httle of the spirits 

 of wine; then gradually add the oil of vitriol: 

 having done this, add, by degrees, the nitrous 

 acid, and the remainder of the spirit of wine. 

 Keep stiring them with a stick or glass rod 

 while you are mixing them or they will 

 inflame. 



In some obstinate cases it will sometimes be 

 proper to add half an ounce of butter of antimony 

 to one ounce and a half of the styptic tincture. 



In some few instances the flap of ther ear swells 

 without any previous ulceration. When this oc- 

 curs, make a pretty free opening with a lancet or 

 penknife, to discharge the contained humour, and 

 then dress the wound with a dossil of lint dipped 

 in the styptic tincture.
