This opening or re-entering angle divides the sole into a body (Fig. 27, /) and two wings or branches (Fig. 27,/). The outer border of the sole unites through the medium of the white line Fig. 31. Fig. / fW\ f -^—^ Vertical section of the iiomy sole magnified: a, Homy frog, with the posterior portion of funnel-shaped openings which contain the horn- the perioplic horn-hand and the periople producing villi of the fleshy sole; they are of which covers the quarters removed from the various sizes; 6, horn-tubes; e, Intertuhular horn, hoof as one piece by maceration: a, trough- shaped depression of upper surface, which is divided posteriorly into the two upper with the lower part of the inner channels of the frog by 6, the frog-stay; c, surface of the wall,—that is, with part of the frog that is joined to the bar and the keraphyllous layer of the wall. This white line (Figs. 27, gr, and 29, ^), of so much impor- tance to the horseshoer, is formed by the horn-leaves, and by those short plugs of tubular horn which are secreted by the villi that are always found at the lower ends of the fleshy leaves. The white line may be said to exist wherever the horn-leaves can be dis- cerned upon the plantar surface of the hoof. It not only passes around the circumference of the sole from heel to heel, but may be followed forward from the buttresses along the bars almost to the summit of the frog. The horn of the white line is soft, unpigmented (white), and possesses so very httle resistance (strength) that it is often found crumbling or even absent in forms the lateral wall of the depression (channels) on upper surface of frog; d, lat- eral surface of horny frog which, in its upper part, adheres to the bar, but below, at d', lies free; e, point or summit of the frog; /, perioplic horn-band; /, periople of the quar- ter
