Corning, in minor surgical operations upon the extremities, has secured prolonged and perfect anesthesia by injecting the fluid into the tissues of the part hein anaes-thetlzed, waiting from two to five minutes for absorption of the solution by t%e ves-sels, and then keeping the cocaine in the tisues by arresting the circulation by a mbher tourniquet applied between the injection and the heart. It is claimed for this method that amputations have been performed with perfect freedom from pain. I have performed circumcision and evulsions of ingrowing nails under cocaine anesthesia, with perfect immunity from aufferin Twenty or 30 minims of a 4 per cent solution should be distributed equally in tfe line of mncisiou. A single punc-ture with a hypodermic needle will s d c e to allow the fluid to be thrown over an area an inch m length, and the effect is 80 rapid that the second puncture can be made through the auaesthetized skin. The needle, after passing through the integ-ument, travels alon just beneath it to its full le h; one or 2 minims are then forced out, the nedle withdrawn a uarter or hapinch, and a like quantity dis-charged. If a deep incision is require>, the needle should he forced into the deeper tissues. One advanhe claimed for this method is that a smaller quantity of cocaine will produce a reater degree of anresthesia, with lea4 constitutional effect. When a large quantity of the solution is used, say 30 minims, the excess should be squeezed or pressed out of the tissues or washed out with the irrigator. As to the length of time for which a tourniquet may safely remain holding the parts beyond full of stagnant blood, operators most famdiar wlth this method of producing anaesthesia claim that half an hour is the limit of safety, while others assert to have kept it applied for a much longer period of time. It is, however, not alwa s necessary to entirely amst the circulation of a part; for if the elastic be applie%close beh~nd the art to be incised, the superficial compressionwill retard the flow at this point, whiletledeeper vt~t.Is'an.1 iruott. rapilla;irs are trr,t rllntrriallg illtcrirred 16th. 11, minx opera-tirlrlr upon tllr trunk, r.lrt., head, nrld nr<.k, all auth irities ngrt,c in the neccieily ior otacrvinz vwot ~rcmurioni.u r llr,re the d n ~ir~ r arrlv I divrrflv 10 rhe rcntcr. ~enara'i inmadetica.-under this head w< shall include nicrous-oxide gas, ether, water.
