less; the piece of tendon sloughed out, and the wound began to heal. 
It had closed when the animal was fetched away by the owner; but the 
writer was unable afterward to learn whether false quarter ensued upon 
the injury. This, from the extent of the wound, the writer would con- 
jecture to have been probable; indeed, false quarter and quittor are the 
general consequences of severe tread. 
Overreach is confined to fast horses; it happens to those which are 
good steppers. When tired, the fect are apt to be moved irregularly ; 
thus, one foot is often in its place before the other has 
been lifted; the result is, that the inner part of the 
hind foot strikes.the outer side of the fore coronet. » 
A wound, and frequently a severe one, is the conse- 
quence. False quarter or quittor is likely to ensue; 
the treatment must be the same as was before de- 
scribed. No poultices are required; these only add 
to the weight of the injured limb, and augment the gvenrescn  ocovrnrne 
distress of the animal. No harsh measures should be  2VRING THE pane 
allowed; the horse has enough to bear; a slough has 
to take place. This is a severe tax upon the strength; all the good 
food and prepared water the animal can consume will not now be thrown 
away; the treatment is materially shortened by the nourishment being 
sustaining of its kind, and liberal in quantity; but the injury should be 
treated only with the knife, and the chloride of zine lotion described in 
the course of this article. 
CORNS. 
Corns are of four kinds—the old, the new, the sappy, and the suppu- 
rating ; all are caused by bruises to the sensitive sole. The shoe is the 
passive agent in their production, when they occur in large, fleshy feet ; 
the thick, unyielding, horny sole is the passive agent, when they are 
present in contracted feet. The coffin-bone, in both cases, is the active 
agent; the wings, or posterior portions of this bone, project backward 
nearly as far as the bars, or immediately over the seat of corn. When 
the horse is in motion, the coffin-bone can never remain still; it rises, or 
rather the wings are drawn upward by the flexor tendon, every time the 
foot is lifted from the earth, and sinks, because of the weight cast upon 
it, every time the foot touches the ground. The wings of the bone, thus 
in constant action, when the horny sole is weak, often descend upon the 
fleshy sole, and bruise that substance upon the iron shoe; what is called 
a corn is the consequence. In contracted feet, where the sole is high, 
thick, and resistant, the horny sole does not descend, even when the 
immense weight of the horse’s body rests upon it. It remains firm and
