352 CORNS. 
be held steady, the seat of corn is lastly squeezed. Should no flinching 
be witnessed, the examination is not esteemed satisfactory until the smith 
has, with a small drawing-knife, denominated a searcher, cut away a por- 
tion of the sole at the seat of corn. 
The sensibility will be extreme should suppurating corn be present; 
in that case the sole must be gradually removed until the pus is released. 
That being done, the shoe should be taken off and the foot put into a 
bran poultice. By this means the horn will be rendered more soft and 
the wound cleansed. The smith, on the following day, must again cut 
the foot, every portion of detached horn being very carefully excised. 
The horn is itself a secretion, and, in a healthy state, is intimately 
united with the source of its origin. When, however, pus is effused, 
this always lies between the secreting membrane and the horn, which 
has been already secreted. The horn so displaced by the presence of a 
foreign substance is called under-run or detached; and all horn, so 
under-run or detached, must be removed. When this operation is prop- 
erly performed, all signs of lameness will have generally disappeared. 
It is usual, however, to tack the old shoe on again; and having dressed 
the injury with chloride of zinc and water—one grain to the ounce— 
there remains only to examine the foot from time to time till new horn 
covers the surface; merely taking precaution for the present to shield 
the wound with a little tow, fastened in its place by a couple of cross 
splints. ; 
When sanguineous or sappy corns are found, the method is, firstly to 
thin the sole, so as to render it pliable, especially over the seat of corn. 
Should a sappy corn have rendered the horn moist for any space, or 
should the discoloration caused by sanguineous corn be of any size, it 
is as well always to open the center of the part indicated: no matter 
should the cut release only a small quantity of serum or a little blood. 
Take away a small portion of horn; pare the sole till it yield to the 
pressure of the thumb. When such a proceeding is necessary, the bars 
may be entirely removed, and the wounds should be covered with some 
tar spread upon a pledget of fine tow. As soon as the orifice is pro- 
tected by new horn, the horse may be shod with a leathern sole and 
returned to its proprietor. 
Such a course would occupy little time—a week at most. Yet the 
great majority of horse proprietors appear to have “flinty hearts,” as 
nearly all of them begrudge the necessary day of rest to the maimed 
animal which has been injured in their employment. The cry, where 
the horse is concerned, is ‘‘toil, toil!” The veterinary surgeon is often 
asked “if absolute rest is imperative.” He is frequently solicited to 
patch up the poor animal, so that it may do a little work. As day after
