IODIDE OF MERCURY. 24J 



animal's feed. For mangey dogs, give ten to fifteen 

 grains once a day, for both horse and dog; give it at 

 night, as warmth assists its action very much. 



(5.) Iodide of Lead. — Too weak for veterinary prac- 

 tice, but excellent for swellings on the body of man. It 

 is only used externally. Iodide of lead is of a lovely, 

 yellow color. 



(6.) Iodide of Mercury. — Bin-Iodide of Mercury- 

 Red Iodide of Mercury, etc. — This preparation of iodine 

 is a medicine that the educated veterinary surgeon 

 cannot do without in the practice of his profession ; for 

 there is nothing which will so well answer his desires 

 and his purposes, as the iodide of mercury. Iodide of 

 mercury is not used internally, in any disease, as calomel 

 contains the same internal action as that of the iodide. 



Use. — Iodide of mercury is used in all cases of indu- 

 ration and swelling of the glands of the neck, tumors, 

 whether of bone or soft tissue, splints, spavins, ring- 

 bones, wind galls, shoulder-joint lameness, thoroughpin, 

 and will answer well for an ordinary blister, for whatever 

 purpose. The only objection to it as a blister over an 

 extensive surface, is its painful operation. 



The iodide of mercury is used as an ointment; one 

 part of the red iodide of mercury to eight parts of hog's 

 lard, well mixed together. This ointment is to be well 

 rubbed into the parts to be cured; swelling will follow 

 its action, but will subside in a few days, if one applica- 

 tion be enough, which will be known, if the enlargement 

 has been broken or has disappeared. If not, apply in 

 from five to six days again, scarcely rubbing so hard as 

 at the first application, as the skin is more easily acted 

 upon at this time. But whether one, two or half a dozen 

 applications be necessary, let sufficient time elapse before
