Ifthe laminee be laid bare in a living horse by removal ofthe wall, it is found that they have tlie power to secretea kind of horn, not a hard, fil:)rous horn like that of thewall, but a softer variety. This function is not veryactive in health or we shcrJd find that the lower edge ofthe wall was thicker than the upper; but it exists, andis very evident in cases of Fig. 11.—Foot with hoof removed showing at the upper part theCoronary band, and below the Sensitive Laminae. In laminitis, the wall at the toe is often pushed for^•ward out of jjosition by a horny mass formed by the-laminae, and so we have the deformity of an excessive^■length of toe. In some cases of long continued sand- FORM AND ACTION OF THE FOOT. 15 ■crack, the irritation of the laminae causes excessive•secretion, and a horn tumor results. The sensitivelaminae, then, fulfil two functions; they offer a firm con-necting medium for the wall, and they secrete the cruel experiment of removing the horny soleand frog of a living horse and then forcing him to stand•on the maimed foot on a level surface, it has been shownthat the laminae are capable of alone supporting theweight of the animal. It has been argued from this thatthe laminae always siipport the weight, and that thehorses foot may be described as being slung b
