The horse in the stable and the field : his management in health and disease. degrees with the lineof the sole, and the upper edge or coronary band should join thesole, so as to leave a moderate substance at the heel; for if toogreat the foot does not expand, and is liable to disease from thatcause; or if too thin and narrow, the foot is weak and gives waydownwards, ending in a convexity of the sole instead of thereverse. The front of the crust is rather more than half an inchin thickness, and in a strong foot of average size gradually diminishing to the quarters, atthe back of which it is generallybarely a quarter of an inchthick, especially at the inner ofthe two. This proportion ishowever confined to the forefoot, ibr in the hind there islittle difference between the toeand quarters in point of thick-ness. The superior border, orcoronary band, is marked by itswhitish color. On its externalFio. 15.—THE UNDER SURFACE OF THE FOOT. surfacc It rcscmblcs thc crustA.

Inexamining the cut of the sole, Fig. 15, it will he seen that thecrust is bent inwards towards the frogat the heel on each side ;there are the bars, which in the natural foot appear as sharpenedprominences, extending from the heels into the centre of the foot,between the sole and the frog, and which are useful as buttresses,supporting the crust from being crushed inwards by the superin-cumbent weight. The sole is the plate at the bottom of the foot,which should be slightly concave downwards, and is fixed to theinner edge of the crust, and the outer sides of the bars, and not totheir lower surfaces. Its usual thickness is about one-sixth of aninch, but it will vary greatly in ditferent horses, and it is thickerwhere it runs back between the bars and the crust. * It is secreted
