At this point it should be noted that there is considerable difference in the technique for handling the lower limbs. Some workers leave the tibia and fibula of the lower leg in the finished skin by simply removing the tissue, adding arsenic, and wrapping the bones with cotton to replace the muscle tissue. Preferably, however, leg wires (discussed below) should be used in adding to these two bones or in place of them. In the former of these two methods, a wire is thrust into the foot all the way out to the end of the longest toe, and then is cut off even with the proximal end of the tibia bone. The bone is then poisoned with arsenic and the wire and bone are wrapped with cotton. The author prefers this last method, removing the tibia and fibula and replacing them with a leg wire and cotton .Nevertheless, the decision must be made as to which procedure will be used, for it involves removing the bones or leaving them intact.
