grain doses of the trituration of arsenicum as directed for cina. For zape-

given early in the morning and late at night. Rock-salt, a lump being 
placed where the animals can lick it, is recommended as a preventive of 
worms. Consult the section on Worms in the Horse.

after damp seasons, and may be taken in with the food and developed in the 
liver, 
Symptoms.—Depression; inactivity; red, watery, or yellowish eyes; 
yellowish skin; standing hair; loss of appetite; offensive smell from the 
mouth and nose; white, watery, offensive dung passes irregularly.

senicum is good for chronic cases, with diarrhoea, prostration and cold 
limbs. Sulphur is needed to complete a cure, when once it begins.
