This form of bandage affords a greater degree of support than any other, but its rigidity necessitates more precautions against the production of sores when it has to be retained for a long period on the limb. It is essential that the plaster should not have been exposed to the air, and tins containing it should be sealed or it may be found to have lost its "setting" power when required for use. To carry the plaster a loosely-woven material is to be preferred. When this has been unrolled, dry plaster of paris is rubbed into it by an assistant. It is then slowly rolled again and each fold carefully filled. Before wetting it, the part of the animal to be bandaged should be covered by a plain bandage, or be padded with cotton-wool, wood-wool, tow, or spongio-piline. Everything being ready, the plaster bandage is dipped in water, and as soon as it is wet through, applied as quickly as possible, consistently with uniformity and neatness. The outside is smeared all over with more plaster of the consistence of cream. A dry roll of bandage is made to cover the whole, and the patient restrained from all movement for half an hour, by which time it should be set and quite hard.
