IODIDE OF POTASSIUM. 367 



Dose. Iodine is given to the horse and the ox in from 

 twenty to forty grains ; for dogs, use from three to six 

 grains. An ointment of iodine is made as follows : Take 

 one part of iodine to eight parts of lard. This is a good 

 ointment to apply to soft swellings on the body of the 

 horse, and should be applied by rubbing with the hand. 



Iodide of Potassium. — Hydriodate of Potash. This 

 is a chemical union of potash with iodine, a costly remedy 

 for horse and cattle diseases, and in most cases can be done 

 very well without. Its action is that of an absorbent, and 

 it is, therefore, used in swelling of the glands, and other 

 parts of the body. To get its full benefit, it should be 

 given in syrup or molasses, so that the iodine will not be 

 lost, leaving the water only behind. 



Dose. From twenty to thirty grains for horses and 

 cattle, repeated three times in the day. For the dog, five 

 grains. 



(1.) Iodide of Arsenic. — Highly recommended by 

 some persons for glanders, farcy and purpura in the horse. 



Dose. Five grains given once a day, in cut or mixed 

 feed. 



(2.) Iodide of Copper. — A valuable remedy, but 

 costly. It should be used only for valuable horses, in 

 cases of debility and loss of condition, mingled with cut or 

 mixed feed. 



Dose. From one to two drachms, given twice or three 

 times in the day. 



(3.) Iodide of Iron. — This is even more valuable than 

 that of the iodide of copper, and is given for the same 

 purpose, and in the same doses. To use the iodide of iron 

 once, will insure its use again. Its high price is the only 

 drawback. Iodide of iron enters into the oowders and
