    composed or made up of concentric coats, or layers of horn, some- what as the coats of an onion, as I have seen it come away or ex- foliate in pieces of this figure, though in a healthy state, a section of this part does not discover this structure, so intimately are the coats united. I have thought also, that this part was often larger, in proportion to the foot, in blood horses, than in horses of the coarser breeds. See Dissertation on the Foot, p. 29. There is a further circumstance in the structure of these parts which appears to be worth noticing, that on carefully dissecting the internal frog I observed that the skin passes down and is every where continued under the horn of the frog; which horn begins by a fine edge at the line or precise point where the hair ceases to grow upon the skin, then passing outside or beneath the cutaneous frog, the organ secreting it, it thickens as it goes on to the middle, and then thins away from the centre to the point of the frog the skin running distinctly under it, the whole way; till reaching the point of the frog, it is lost in the sole. The breaking up of the Frog-stay therefore, brings this same skin into contact or exposure to extraneous bodies, and it becomes the seat of irritation and tenderness. A sort of cuticle also is seen covering the horn above described, and seems to run between the two halves of the frog; though whether it be so is not readily decided. The skin appears to thicken considerably, flowing irregularly under the middle of the frog, and becomes more vascular and con- tains a streaky ligament which covers its surface within, and is again containing or involving it; the middle mass is a sort of granular liga- ment, for when you cut it, it starts out in elastic granular points more so than any other of the ligaments of the foot. These circumstances are best seen by laying open the frog longitudinally with a sharp scal- pal, and reflecting and turning back the edges.
