You will see, therefore, the importance o-f matching the sprocket holes perfectly. In the operating room it is customary to make patches with the fingers.

Also with the fingers the pressure cannot possibly be applied evenly. Until recently there has been no film mender suitable for use in the operating room. ooo ooo o ooooo a Figure 75. To Make a Patch cut the film, as shown in Fig. 75, leaving a stub as shown at A. This stub should be not less than one-eighth inch and not more than three-sixteenths of an inch in length.
