The T-bandage is used to bandage the crotch between the thighs, or around the forehead and over the top of the skull. (See Fig. IV, p. 134.) In the former case, the ends 1-1 are put about the body as a belt, and the end 2 is brought from behind, in the narrow part of the back, down forward between the thighs, over the crotch, and up to the belt in the lower part of the belly. The figure-of-eight bandage is used on various parts, and is illustrated in the bandage called spica of the groin, Fig. IV, p. 132. Beginning with a few circular turns about the body in the direction of 1, the bandage is brought down in front of the body and groin, as in 2, and then about the back of the thigh up around the front of the thigh, as in 3, across the back and once around the body and down again as in 2. Other bandages appropriate to various parts of the body are also illustrated that by their help the proper method of their application may be understood. See pages 132, 134, 136, 137. The triangular bandage (see p. 88) made from a large handkerchief or piece of muslin a yard square, cut or folded diagonally from corner to corner, will be found invaluable in emergency cases. It is easily and quickly adjusted to almost any part of the body, and may be used for dressing wounds, or as a bandage for fractures, etc. [Illustration: PLATE III. Fig. I. Fig. II.
