This new socket is for amputation below the knee. The adjustment is made at the back of the socket instead of at the front, as in the lacing sockets heretofore made. The improvement is so marked that the wonder is we did not make the change earlier. Much of the weight on the stump is taken just where the socket was previously made to open, and it was necessary to reinforce the lacing with a strap. When laced in the back of socket the front is stronger, more comfortable, and dresses more smoothly; furthermore, there is more shrinkage of a stump in the calf than in front; and in being able to make the adjustment in the back part of the socket, it is kept nearer the shape that will conform to the shape of the stump than when laced in front. This socket is illustrated in the various engravings representing legs for below the knee amputation. See frontispiece, No. 204, No. 227 and No. 228. [Illustration] PART II In this part we give descriptions and illustrations of ordinary styles of legs, such as we have made here—with various modifications and improvements, as suggested by time, wear and experience—for forty-five years. Excepting the WALKEASY leg, described in Part I, there are no better nor more reliable artificial limbs made anywhere by anyone, _and the prices are much below_ those charged by other manufacturers. The various styles are: Wooden foot with ball-and-socket ankle joint and wooden socket. Wooden foot with ball-and-socket ankle joint and leather lacing socket. Wooden foot with hinge ankle joint (army and navy or two-ball) and wooden socket. Wooden foot with hinge ankle joint (army and navy or two-ball) and adjustable leather lacing socket. Foot with sponge-rubber or felt removable sole and rigid ankle and wooden socket. Foot with rigid ankle and adjustable leather lacing socket. The cords and springs used in the legs with articulated ankle joints are the same as are used in the WALKEASY leg. The springs are rubber used by compression, imparting easy, uniform motion, their power and action being regulated by simply turning a nut, so that the wearer may adjust them to suit his own peculiar gait. In walking, when the weight of the body rests on the ball of the foot, the spring in the back part of the leg (heel spring) is firmly compressed, and when the weight of the body is thrown forward on to the other foot the spring rises and carries the foot forward to its place with very little effort of the wearer, assisting greatly in carrying the weight of the leg. The prices for legs described in this part, for amputation at any point above the ankle, are, including suspenders, stump socks, etc., complete: $50, warranted for one year. $60, warranted for three years. $70, warranted for five years. A copy of the warranty is given on page 18.
