    Baileifs Improvements in Trusses for Hernia._ The first improvement consists in the construction of the hearing pad applied to the spine, and forming the fulcrum of the spring. I make this somewhat of a saddle form with two hearers and an inter•*_ vening arch, so that when applied to the spine the pressure is trans¬ ferred to a point on each side of the hone, thus affording ease to the ^ patient and preventing the pad from slipping.^ The spring is adjusted to the pad hy means of a screw passing through a slot, or one of a series of holes, according to the required position of the pad over the hernial sac. The next improvement consists in the construction of the hernial pad 10 covering the hernia. I divide the convex surface of this with four separate curvilinear surfaces hy means of two grooves or indentations, which, crossing each other, in the centre, forni a small concayity and four bosses or inequalities of projecting surface, which pressing separately on the parts covering and surrounding the hernial sac render it fixed in its position, and keep up an undisturhed and unintermittent pressure which is conducive to cure. These parts I connect hy the usual spring and screws common to what are called opposite sided trusses, hut instead of leather I coat the steel and metal of which the pads and spring are made with vulcanite or 20« varnish. I make the double truss, with the sarue pads, only attaching the springs in the same manner as heretofore. The hernial pad may he secured hy a screw passing through the spring, and it may he made of a solid piece of vulcanite, but the compound or duplicate pad which hears on the sides of the spine should he dished or hollowed out, 25 presenting concave external surfaces, and the screw will then take its, hearing on the arch. By these improvements all extraneous fastenings, such as straps, hands, or buckles, are dispensed with, except in certain cases, and especially with double trusses straps may he used, the truss being 30, self-.fastening when once adjusted in position; it is comfortable in wear, incapable of being soiled, and will last for a much longer period than the ordinary truss. In order to form the double truss I propose to fasten the backs of the. springs on the saddle hack, hut, by^ preference, I make each of the 35 duplicate hack pads with a flat surface in lieu of the convexity, and I screw each spring into the side pads on their flat surfaces. Thus, each
