form existed only in theory, as there are none in practice. It is necessary, however, to remark, that the degree of inclination must be regulated by the previous state of the foot, and its propensity to contraction. . . . When it is recollected that the horny sole, if not diseased, is concave, it will in course admit of a convex surface being applied to it; and when the superfluous parts of the horny sole produced since the last shoeing are removed, and the crust at the quarters is preserved firm and good, there is scarcely an instance where this mode of shoeing cannot be put into practice, and sufficient room be left also to pass a picker between the shoe and the sole to the nails.'

The preparation of the foot, previous to shoeing, consisted in the removal of all the superfluous growth: 'When hoofs are protected by shoes, the consumption of horn by wear and tear is nearly prevented; but as the growth of the hoof is constantly going on, it is evident that all the superfluous parts will require to be removed at every period of shoeing, otherwise it would run into a state of exuberance similar to the human nails if they were not cut. The first part to be reduced is the toe, which should be removed with a knife or rasp on the sole side of the foot, keeping in view the necessary curve: the next parts are the heels, which should, if they descend below the frog, be rasped to bring them on a level with it: having attended to these two points, it will be seen how much it is necessary to remove from the quarters, leaving them full and strong, but in a straight line from the heels to the curve, which allows the foot, when in action, a flat part to land on, and describes a space equal to the landing part of the foot when shod with a parallel shoe.
