(B) 



1. Place one large sheet of zorbik with 32-inch (81.3 cm.) side parallel 



to edge of table. Place two face-pieces in center with 15-inch 

 (38.3 cm.) side parallel to edge of table. If the zorbik is of poor 

 quality two large sheets may be necessary. 



2. Place wooden frame in center of zorbik with 12-inch (30.5 cm.) side 



parallel to edge of table. (Frame should be made 12xl8x% 

 inches or 30.5x45.7x1.9 cm., inside measurements.) Place 

 sphagnum in frame filling it evenly but not packed. 



3. Cover sphagnum with a thin layer of non-absorbent cotton. Remove 



frame. 



4. Fold zorbik from sides to center over sphagnum and cotton; then fold 



ends over pad. (When pressed down the zorbik envelope should 

 measure approximately 1214 x 181/4 inches, or 30.9x46.3 cm.). 



5. Pass zorbik envelope to separate table for gauze. 



(C) 



1. Place gauze on table with selvage right and left. 



2. Place zorbik envelope in center of gauze with 12^-inch (30.9 cm.) 



edge parallel to edge of table. 



3. Place the backing of non-absorbent cotton on the pad with a margin 



of cotton extending well beyond the zorbik envelope on all sides. 



4. Fold gauze from left to right over pad; then from right to left over 



pad. Turn the pad face upward and muff ends of gauze on face 

 of pad, i. e., on paper side of pad. 



5. At this point, if gauze has been wrapped snugly, the pad should meas- 



ure 13%xl9% inches (35x50.1 cm.) or a little less. And if 

 all measurements have been carefully followed there should be a 

 margin of non-absorbent cotton on all sides of the zorbik envelope, 

 varying from scant % to % inch (.6 x 1.9 cm.) in width depending 



upon the firmness of the tissue envelope and the stretchiness of 

 the zorbik. 



6. Pass for careful inspection, then sew both ends and along the back 



with medium sized stitches. 



7. Pass through wringer. Pad will now measure 14 x 20 inches (35.6 x 



50.8 cm.) and weigh 4 to 41/2 oz. (113 — 128 g.). Weight must 

 be kept within these limits. 



8. Tie in packages of 5 with the face side up, except the top one, which 



should be face down; thus a cotton side is exposed on top and 

 bottom of the package. 



9. Label: "5 Sphagnum Absorbent Pads 14x20 inches (or 35.6 x 50.8 



cm.). N. B. Cotton side does not go next to the wound." 



(e) Directions for making dressings for base hospitals in U. S. 



Base hospitals in this country seldom, if ever, need dressings as large 

 as those just described. Consequently the sizes of sphagnum pads for 

 their use have been greatly reduced to meet their particular needs. The
