364 THRUSH. 
offensive through being mixed with the decaying horn; the smell is most 
abhorrent ; frequently it taints the interior of the place, and to the edu- 
cated nose thus makes known its presence. 
The first thing is to clear the stable, then to cleanse it thoroughly. 
Bed down the stalls with new straw, and attend to the 
animals themselves. Wash,the feet well with water, in 
every pint of which is dissolved two scruples of chlo- 
ride of zinc. The fetor will thus be destroyed, and the 
animal be made approachable. Place some of the fluid, 
to be used as required, near the smith, while the man 
cuts away the diseased frog. All the ragged parts 
are to be excised. The knife is to be employed until 
all the white, powdery substance is effectually removed.

cen ntive or, The knife must then be used fearlessly. Every par- 
hene neoven, ““¥® ticle of the colorless investment of the frog must be 
excised. This is absolutely necessary toward the cure. 
It must be accomplished, although the flesh be exposed, or a large, 
bulging frog be reduced to the dimensions indicated 
in the annexed engraving. 
Then the shoe is to be nailed on, and the horse to 
be returned to a clean stall. 
The cause being removed, the effect will soon cease. 
No ointments are required. A little of the chloride 
of zinc lotion, three grains to the ounce of water, may 
be left in the stable, and the keeper should receive 
directions to bathe the frog with this once a day, or oftener if required. 
A piece of stick, having a little tow wrapped round one end, should also 
be given to the man, so that he may force the fluid between the cleft of 
the frog. No greasy dressing need be employed. The ordinary shoe 
is to be used. The diseased part is to be left perfectly uncovered, so 
that it may be the more exposed to the sweetening effects of pure air, 
while the earliest indication of any further necessity for the knife may 
be readily perceived. When the stench has disappeared, a little of the 
liquor of lead, of its original strength, will perfect the cure; and all that 
is requisite to prevent a return of the disorder is a reasonabl@ attention 
to the cleanliness of the stable. 
At this place, however, the reader may well reflect that, if the filth of 
the stable is capable of rotting the resistant and insensitive horn of the 
horse’s foot, how much more is it likely to affect some of those delicate 
structures of which the bulky frame of the animal is composed! The 
air in which a man might object to live is altogether unfit for a horse to 
inhale. It is true, animals have breathed such an atmosphere, and con-
