When it is necessary to bend the pasteboardat a sharp angle cuts should be made in it in suitable directions andplaces and the overlapping portions stitched together. Leather and felt are prepared in the same manner, A material ismade for this purpose of woven tissue soaked in shellac which can besoftened by dry heat and hardens more rapidly than the is used in strips one-sixteenth to one-eighth inch thick Fig. Posterior gypsiun spliut or gutter. and is softened by immersion in hot water. The stickiness of thesurface can be mitigated by covering it with muslin. Plaster-of-Paris, or gypsum, splints can be made of the preparedbandages or of some loose-meshed material soaked in plaster the prepared bandages are used they should be thoroughly wet inthe usual way, squeezed out, and then rapidly unrolled back and forthto make a splint of the desired dimensions. From eight to fifteenlayers are required to give the needed solidity. Plaster cream is pre-pared by sifting the dry plaster into water and then spreading theplaster thus moistened upon the selected material previously cut tosuitable shape and wrung out in water. The number of layersneeded will depend upon the thickness of the material, and care mustbe taken thoroughly to work the plaster into them. The use of hotwater or the addition of salt or zinc oxide to the water will haste
