Dr. Crile, in employing his anoci principle, begins the injectionof the local anesthetic after the patient is unconscious from the gen-eral anesthetic; he prefers to use per cent, quinin and urea for 196 LOCAL ANESTHESIA blocking purposes, and the technic is the same as if the operationwas to be performed under purely local methods alone, infiltratingor blocking all regions, consequently the methods described in thisbook can be followed. We, however, feel some hesitation in usingquinin and urea too extensively and in all tissues for this purpose;while it does produce a lasting analgesia for several days to a week, itsobjectionable quality of often producing massive fibrinous exudatesin the infiltrated area, with an occasional tendency to suppuration,must not be lost sight of, as pointed out in the chapter dealing with rl.

The em-ployment of the anoci principle is graphically illustrated in Fig. 22,taken from Crile. Figures 23 and 24, taken from the same author, showin a striking way the effects of shock and fear upon the brain-cells ofanimals. Figures 25 and 26 show the comparative results obtained bydifferent methods of anesthesia, and ill
