Mange, sometimes called" Texas itch," because many horses coming from Texas were infested with it, is due to a parasite which burrows in the skin. The parasites are of three varieties, viz.: the sarcoptes, dermatocoptis and dermatophagus.

Symptoms. - There will be intense itching of the skin, increasing the more it is rubbed. Small blisters or pimples will form, and, when broken by rubbing, will discharge a gluey substance that dries on the skin. The hair will be rubbed off and the skin thickened.

Treatment. - Make a wash of unslacked lime, one pound; sulphur, two pounds: water, two gallons; slake the lime in the water first, then add the sulphur and boil and stir until thoroughly combined. Select a warm day and first wash the animal with warm water and soap; when nearly dry apply the wash with a large swab or mop, rubbing it well into the skin. It should be repeated in a week. It generally takes about three applications to effect a cure. Where a large number of animals are affected, a tank, such as that used for dipping sheep, can be used. The disease is contagious and all harness and blankets used about it should be washed in hot water and soap and then sponged with a five per cent solution of carbolic acid.
