Cattle are liable to receive injuries to the eyes from brush and weeds while grazing; also from chaff and other substances getting into the eye, causing it to become inflamed and throw off a watery discharge.
Treatment. - Examine the eye carefully to remove any foreign body that may be there. If there is much pain, bathe the eye for ten or fifteen minutes night and morning with water as hot as can be borne with the hand. If the irritation is only slight, cold-water bathing will be all that is necessary. In very severe cases the animal should be kept in a dark stable in the brightest part of the day.
