tact with the affected animal (a few drops of carboHc acid 
in warm water). This will kill the insect and prevent the 
disease from spreading. Feed soft food and give a teaspoon- 
ful of sulphur in the food twice a day. 
10. Ringw^orm. 
Causes. — Ringworm is also the result of the burrowing 
into the skin of a parasite. It is much more frequently met 
with in cattle than in horses. 
Symptoms. — It often attacks around the eyes and nose. 
The germs or parasites work in circles, which causes the hair 
to fall off and leave round, bald spots. If not checked, it 
soon spreads over the body. Men are liable to contract this 
disease from horses and cattle, and horses and cattle are 
liable to contract it from men. 
Treatment. — The best and cheapest remedy, and one 
never known to fail in our experience, is crude petroleum oil 
as it comes out of the ground. This can be bought at almost 
any store in the country or city. Paint it Over the spot where 
the ringworm is working, allowing it to extend a half-inch 
over the edge of the ringworm on to the healthy skin so as 
to check the spreading. Apply this once a day until the ring- 
worm is gone. If it blisters the skin, stop using it for a day 
or so and then continue the applications. Another very good 
remedy is tincture of iodine. Paint as before, every two or 
three days until the ringworm is gone, 
11. Lice. 
Horses may be infected with common horse lice or hen 
lice. Hen lice are very small, reddish looking, and travel 
very fast. Being too near a lousy hen house, or the roosting 
of hens in the stable, may account for them. Horse lice are 
larger than hen lice. They have a long, brownish body, 
travel very slowly, are generally found on horses that are 
turned out and have long, dirty hair. 
Symptoms. — The cOat looks rough. He does not thrive 
well, keeps rubbing his sides, neck and tail until he has the 
hair worn off, and seems to be in perfect misery. The lice 
may be seen upon close examination.
