"The next and laft Bone of the Foot is the Coffin-bone, fo called (I fuppofe) from its hollownefs on its under-fide. Its figure is femilunary or Half-moon-fafhioned. It is thick at its top, (where it has cavities to receive the heads of the lower end of the little Paftern) but thin and broad at its bottom and toward its edges, for its more firm fixing upon the ground. Its fubftance is fungous or fpongy, having innumerable little holes piercing through its fides for the paffage of the Veffels; as alfo very many fmall Sinus’s whereinto are implanted the ends of the Tendons of the Mufcles that move the lower part of the Leg, and the Foot: whofe Fibres being at any time affected either by bruifes, ill fhooing, or by ftanding in the water after hard riding whilft the Horfe is hot, or but by ftanding ftill in the Stable for feveral days without having the Feet ftopt up, and the like; I fay the tendinous Fibres being affected by thefe or other means, caufe the Horfe to have fuch great pain in his Feet, that he can fcarce endure to tread upon them; which lamenefs we call a Founder. Now this diftemper is fo much the harder to cure by reafon thefe Fibres lie fo far out of reach, moft of them running on the upper fide of the Bone (betwixt it and the Hoof) and not to its bottom; fo that the Hoof growing upon the fides as the Soal doth at the bottom, there is great hazard but we fhall mifs of effecting a cure, if we onely pull the Soal out, and do not cut part of the Hoof off alfo. This is not my bare opinion, but the experience of thofe that have had good fuccefs in curing foundred Horfes, who by rafing the Hoof from the Coronet or top of it to the very bottom, in five or fix places, untill they have made the Bloud come, and then applying their remedies to thofe places, have made thofe Horfes found, whom the drawing out of their Soals would not cure."
