A brace should never be ajoplied to a deformed and rigid footbecause it cannot adapt itself to the support; the spasm andrigidity should be first relieved by the preliminary treatment,that will be described in the consideration of this class of cases. The Construction of the Brace.—To properly construct a braceto meet these conditions, it is necessary to provide the mechanicvtith a jDlaster cast of the foot, taken in the attitude in which onewishes to support it. Such a model may be easily and quickly. made in the following manner Fig. The attitude in which the plaster cast should be taken. This attitude isimportant, because in it the foot assumes the best possible contour. If the soleis simply pressed downward into the plaster cream, the ordinary method of mak-ing the model, the shape will be found to be quite different from that taken inthe manner illustrated. The piaster Cast.—Seat the patient in a chair; in front of himplace another, preferably a rocking chair, somewhat less inheight; on it lay a thick pad of cotton-batting and cover it witha square of cotton cloth. Put about a quart of cold water intoa basin and sprinkle plaster-of-Paris on the surface until it doesnot readily sink to the bottom; then stir. When the mixture isof the consistency of very thick cream pour it upon the patients knee is then flexed, and the outer side of the foot,previously rubbed with talcum powder, is allowed to sink intothe j)laster, and, the borders of the cloth being raised, the pla
