The formula is as follows: Powdered starch, one ounce; isinglass or gelatin, one ounce, solution of potassium silicate, one quart; pulverized boric acid, one-half ounce. Mix the starch with the solution of silicate of potash by shaking from a pepper box and stirring constantly; reduce the gelatin to the consistency of mucilage with boiling water and mix with the first two (better soften the gelatin with cold water first). Then put into a jug of double the capacity and ferment at room temperature for three or four days; then add the boric acid, mix well, and it is ready for use. If too thick after standing, thin it with boiling water; keep corked. Apply a silk stocking or a roller bandage and then apply a coat of this preparation with a brush and repeat until three or four layers have been applied or until the splint is thick enough. It may be cut after hardening, and eyelets and laces put in.
