He states that the injury of the vessel which lieson the inner side of the nerve is hardly to be feared, but it should firstbe made sure that the point of the needle is not in the vessel, by IT 258 LOCAL ANESTHESIA resorting to a little aspiration before the injection is made by slightlywithdrawing the plunger. Should it be found that the vessel has beenpunctured, no unpleasant consequences are likely to result if theneedle has been fine. The following experiment indicates the results of an injectionmade in this manner: Experiment i (Dr. B.). One-half cubic centimeter of a i per cent, solution with idrop of adrenalin (i : iooo) was injected in the above-described manner, and almost im-mediately anesthesia appeared as indicated in Fig. 54, No. 1, and lasted for three affected area on the extensor surface of the foot and toe is indicated by the Fig. 54.—Lines of subcutaneous infiltration and resulting areas of anesthesia in foot. (From Braun.) This procedure was once employed for opening an abscess andremoving a foreign body from the sole of the foot. The anesthesiaextends to the metatarsals and tarsus: Experiment 2. Two cubic centimeters of per cent, cocain solution with 4 dropsadrenalin solution, injected subcutaneously over the inner ankle, beginning behind thetendo achillis and extending around to the middle line of the joint in front. This willmeet the terminal branches of the internal saphenous nerve; the extent of the resultinganesthesia is shown in Fig. 54, No. 2. The injection in Experiment 2 reaches the terminal branchesof the internal saphenous nerve, and may often be co
