Twelve oclock, an injection of 1 of 2 percent, cocain solution in the above-described way, the needle had exactly met the nerve-trunk, as indicated by the radiating paresthesia. No constriction. Immediately afterthe injection occurred a marked radiating paresthesia and sense of warmth in the : 10, complete regional anesthesin of the nerve; anesthesia of the skin is indicated, asin Fig. 34, No. 2.
