These will sometimes appear on the skin of a hog, especially about the
root of the ears and of the tail, and at the flanks. They are not at all
to be confounded with mange, as they never result from any thing but
exposure to extremes of temperature, while the animal is unable to avail
himself of such protection as, in a state of nature, instinct would have
induced him to adopt. They are peculiarly troublesome in the heat of
summer, if he does not have access to water, in which to lave his
parched limbs and half-scorched carcass.
Anoint the cracked parts twice or three times a day with tar and lard,
well melted up together.
