    JF. 8f TV. Arthur's Improved Truss. to either side. This bar in addition to its leverage has also this great advantage over ordinary crutch straps of passing over very sensitive parts without pressing on them. The terms balanced truss, and balanced over the hernia, mean the adjustment of its surface above and below the 5 arms to the resistance opposed to them, as before stated, and the plate with its pad may for this purpose he considered as one, so that the arms if they were attached at or even above the centre of the plate would still not disarrange the balance if at the same time the pad of extra strength and extent superiorly were substituted. 10 In order however that our Invention may he fully understood and readily carried into effect, we proceed to describe it more particularly by reference to the accompanying Drawings, in which are represented our new and improved truss, with different modes of applying the same. 15 Description op the Drawings. Pig. 1 is a full-sized front view of a right inguinal truss in its most usual form, a, a} the plate of thin metal covered with leather; h, b, the extension of the india-rubber pad; c, the cross bar or arms covered with leather; d, the button on the outer arm; e, the buckle on the inner 20 arm for the attachment of the pelvic strap. Pig. 2 is a cross view partly in section on the line f9ft of Pig. 1, shewing the curvature, the black lines shewing the metal or other hard substance used in its construction. Pig. 3 is a longitudinal view partly in section on the line g, g, of 25 Pig. 1, also shewing the curvature. Pig. 4, shews the same truss applied by means of the pelvic strap h. Pig. 5 shews our Invention applied in a case of double inguinal hernia, the pelvic strap h is attached to the outer side of each truss and passes round the pelvis, and the short strap i connects the inner 30 sides of both trusses. Pig. 6 shews its application in a case of left femoral hernia, the extension of the pad therein being marked with the letter k. Pig. 7 shews a second mode of its application to femoral hernia with its course from above downwards and outwards over the pubic end of 35 Poupart’s ligament.
