The injection in Experiment 2 reaches the terminal branchesof the internal saphenous nerve, and may often be combined with the THE UPPER AND LOWER EXTREMITIES 259 injection of the posterior tibial, as in Experiment 1, for anesthesia ofthe inner side and sole of the foot. In commenting upon these experiments, Braun states that asubcutaneous injection, made across the extensor surface of theankle-joint, reaches only a few of the fibers of the internal saphenousand produces only a limited area of anesthesia on the back of thefoot, the same as in a corresponding injection made on the back of thehand, while a much more extensive area is affected if the injection ismade slightly higher, as in Experiment 3, where the superficial branchesof the peroneal nerves are Fig. 55.—Disarticulation of third toe. (From Braun.) Experiment 3. Three cubic centimeters of per cent, cocain solution with the ad-dition of 10 drops adrenalin solution (1: 1000) was injected a hands breadth above the outerankle, across the axis of the limb, from the tendo Achillis behind to the edge of the tibiain front. After six minutes the skin, as indicated in Fig. 54, No. 3, had become anestheticand remained so for three to four hours. In discussing this experiment, Braun states that this injectionreaches all of the superficial fibers of the peroneal nerve, the anes-thetic field extending from the territory of distribution of the internalsaphenous at the inner ankle and inner side of the foot across thedorsum to the outer side of the f
