severity, the formation of pus may be expected, and it is 
then time for the paring to be carried further, until the 
question ‘ pus or no pus ?’ is definitely settled. 
Should the moisture be due simply to the presence of 
the inflammatory exudate, then poulticing alone will 
have the desired effect, and the pain will be lessened. 
With the decrease in pain the poulticing may be dis- 
continued, and the horn over the seat of the injury 
dressed with some antiseptic and hardening solution. 
Sulphate of zinc, a mixture of sulphate of zine and lead 
acetate, sulphate of copper, or the mixture known as 
Villate’s solution,* may either of them be used. Suitably 
shod, and with a leather sole for preference, the animal 
may then again be put to work. 
When dealing with suppurating corn, then, a consider- 
able paring away of the horn of the sole becomes a matter 
of necessity. The freest possible exit should be given to 
the pus, and this even when an opening has already 
occurred at the coronet. Unless this is done, and done 
promptly, the putrescent matter still contained within the 
hoof will make further inroads upon the soft structures 
therein, and later upon the ligaments, and even bone itself. 
Having given drainage to the lesion by the dependent 
orifice in the sole, poulticing should again be resorted to. 
and maintained for at least three or four days. The 
poulticing may then be discontinued, and the openings in 
the sole injected with a weak solution of Tuson’s spts.

any other combined antiseptic and astringent. The success 
of the treatment is svon seen in the cessation of pain and
