THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE 569 Relative to the innervation of the face, observations which wehave made after alcohol injection as to the capacity for regenerationof the sensibility are of interest. Figure 230 shows the area of diffu-sion of the analgesia twelve days after the alcohol injection into theganglion Gasseri; Fig. 231, the same twenty-five days after. Wesee clearly how, especially in the frontal regions of the margins, col-lateral tracts of sensibility are developed. In the same category theobservation belongs that after ganglion injection the anesthesia diedout earliest in those regions whose nerves were treated earlier with.

If we compare our areas of anesthesiawith the anesthesias found by Krause, after the extirpation of theganglion Gasseri, then we find that ours are more extended andapproach more closely to the statements of the anatomists. This isattributable to the fact that our tests were undertaken immediatelyafter the injection, while Krause, for independent reasons, firstundertook the tests of sensibility eighteen days after the operation. 2.
