It is most conveniently described as consisting of three divisions,—wall, sole and frog. "The wall, or 'crust,' is that poiiion of the hoof visible whilst the foot rests on the ground. It extends from the coronet downwards and outwards in a straight line to the ground; thus the lower circum- ference is greater than the upper. The front portion shows the greatest height and obliquity (about 50 deg.). Diminishing in these respects as it runs backwards, it becomes nearly upright at the quar- ters, the inner one more especially. The Bars.—"On reaching the heels the wall is turned in upon itself and continued towards the centre of the foot, w^here it is lost in the structure of the sole. These inflexions are known aS the bars; they serve two important ends. By the turning in of the wall a portion of sole is embraced on each side, which affords solidity to the posterior parts of the foot; they also protect the frog and sole from undue pressure, by j)re- sentino; a bearino' surface level with the wall. Features of the Wall. — "By detaching the wall we are enabled to see variations in its thickness; it is thickest at the toe, becoming grad- ually thinner towards the liecls, thus offering strength and so- lidity at one part to resist wear, at another presenting ])liancy to ward off concussion. A glance at any sound hoof will show that this is true in respect to both fore and hind feet. Why so many authors say that in the hind foot the wall is thickest at the quarters, I know not. They must either have examined unnatural feet or rested satis- fied with the statements of previous writers. The inner surface of the wall is seen covered by a number of thin, horny plates, pro-' jectiug inwards and running parallel to each other fro
