If thesole be cut away and weakened, the wallhas to support unaided an excess of weight,and it becomes broken and diseased. Wall,sole, and frog must be kept proportionate ifthe proper relations of the whole hoof areto l)e maintained. Internal Structure of Hoof.—Al-though the hoof is a firm, strong, protect-ing covering to the sensitive foot witliinit, very serious injury to the horse resultsfrom defects in its structure which are oftenoverlooked. These will be appreciated morereadily when it is known that within thehoof is a particularly delicate and complexarrangement. When a hoof is removed withcare, a beautiful, sensitive structure is ex-posed, having a contour exactly matchingthe inner surface of the hoof (figs. 626, 627).The inner surface of the wall is covered with rows of thin, horny platesrunning from above downwards parallel to each other, all sloping forwards

These are called the sensitive laminae, and in the livingfoot are dovetailed between the horny laminse of the wall so as to afforda firm, secure attachment between the two. The sensitive frog and soleare firmly attached to the corresponding horny parts, but instead of platesthe connecting medium here is a mass of little papillae, so closely arrangedas to give a velvety appearance and feel to the exposed surface. Thissensitive layer, known to fariiers as the quick, is bountifully suppliedwith nerves and blood-vessels.
