The character of the fluid in our casemust be a matter of speculation, althoughin the absence of signs of infection, and inview of the fact that it appeared secondar-ily to the formation of the aerocele, it SUMMARY Reviewing the succession of events inour recent case, we note that a number ofdays after the injury, air entered the cranialcavity. Two weeks later the cavity formedby this air had extended, but had becomepartially fluid-filled. With the entrance offluid the cavity did not shrink concentri-cally, did not really become smaller as a
