Lice on Horses, 
Lice, in a majority of cases, may be attributed to want of cleaa- 
liness; for they are rarely if ever seen on the body of an animal 
with clean skin. Brush and curry-comb, and clean stables, are, 
therefore, the preventives. 
A short time ago I had occasion to visit a stable, located ia 
Waukegan, Ill. There I saw a horse almost perfectly hairless, ex- 
cept the mane and tail. I asked the owner what occasioned the 
depilation of the hair. He informed me that the horse's body waa 
completely infested with lice; that he had tried all sorts of rem- 
edies without success, and, at last, thought he would try kerosene 
oil, and, accordingly, rubbed the body all over with it, using about 
two quarts. He said “it killed all the lice, but came very near 
killing the horse. It made him perfectly crazy ; his limbs became 
swollen to the proportions of a young elephant, and the hair a(l 
fell off.”

Mix. 
This should be thoroughly rubbed all over the body by meana 
of a stiff brush; at the expiration of four hours, carefully wash 
the horse all over with soft soap and warm water. It may be 
necessary to make a second and even a third application, on suc- 
cessive days, ere the parasites are all killed. The parasites can be 
seen with the naked eye; therefore the owner of the horse must 
be the judge as regards the number of applications needed. 
At a meeting of a Farmer’s Club, “Lice” formed the subject 
for discussion. Dr. J. R. Smiru explained that lice, as well as 
aj| similar insects, breathe through holes in the body. These 
holes are minute spirules, constantly kept open by an elastic ring, 
and surrounded by a fringe of extremely delicate hair, which pre- 
vents the intrusion of any solid particles. To kill the insect it 
is only necessary to close these breathing-holes, and this is done 
by smearing them with any kind of grease or oil. You may 
catch a caterpillar and examine him with a magnifying glass, and 
you will find these spirules arranged in twce rows, one on each 
side; ‘hen, if you take a moth or butterfly, you will find the
