This makes its appearance suddenly. The animal, having remained in a
passive and stupid state, suddenly appears much disturbed, to such a
degree that it makes irregular movements, strikes its head against every
thing it meets, scrapes with its feet, places itself quite erect
alongside of the sty, bites any thing in its way, and frequently whirls
itself round, after which it suddenly becomes more tranquil.
_Treatment._--Give half an ounce of Rochelle salts, in a pint of
thoroughwort tea. If the bowels are not moved in the course of twelve
hours, repeat the dose. A light diet for a few days will generally
complete the cure.
