DISEASES OF THE SKIN. 293 



RINGWORM. 



This disease is due to a parasite belonging to the crytogama, 

 or vegetable kingdom. It is contagious; attacks animals, and is 

 communicated from one to another, and from animals to man. 



Symptoms. — Small pimples appear on various parts r " 'he 

 body. After some time the hair begins to fall out in circular 

 patches, and unless stopped the patches soon spread over the 

 entire body. Its favorite seat is on the hind quarters, back and 

 neck. It is accompanied by slight itchiness. 



Treatment. — First remove the crusts by washing the parts 

 with warm water and soft soap. Apply to the parts the carbo- 

 nate of potash or the iodine ointment — iodi potass, iodi a a, one 

 drachm ; adeps, one ounce. The carbolic acid lotion may be used. 

 Nitrate of silver, twenty grains to a pint of water, may be used. 



LICE 



Are seen in poor, uncared for, half-starved animals and in 

 very old animals. The treatment is to clip the animal and wash 

 with a decoction of stavesacre, one ounce of the powdered seeds 

 to a pint of water. Carbolic acid lotion, used in the same pro- 

 portion as recommended for mange, is an effectual remedy. 



POULTRY LICE. 



These lice sometimes get on horses and cows, causing great 

 itching, the animal scarcely being quiet for a moment. He rubs 

 against everything near him. At night his torments increase. 

 A horse infested with these lice will fall off in appetite and grow 

 thin. 



Treatment. — Treat as for horse lice, 'and whitewash the 



stables. 



FLEA. 



Where the animal is infested with fleas, it should be dusted 

 with the Persian insect powder. Attention should be paid to 

 cleanliness.
