(2) A patient received a wound at Doornkop which traversed the calf in an obliquely antero-posterior longitudinal direction. Three weeks later a soft fluctuating swelling developed at the inner margin of the tendo Achillis occupying the lower third of the leg. Neither pulsation nor murmur was detected. There was anaesthesia in the area of distribution of the posterior tibial nerve. No tendency to further increase was observed, and operation was postponed. The temperature was normal. (3) An Imperial Yeoman was struck at Zwartskopfontein at a range of one hundred yards. The man rode four miles on his horse after being hit, but the horse then fell and rolled over him twice. The man was treated successively in the Van Alen, Boshof, and Kimberley Hospitals, and from the last he was sent to Wynberg which place he reached on the twenty-third day. When admitted into No. 2 General Hospital the wounds of type form and size (_entry_, in posterior fold of axilla; _exit_, 1-1/2 inch below junction of anterior fold with arm) were healed. The whole upper arm was swollen and discoloured, while an indurated mass extended along the line of the vessels into the axilla. This was considered a blood effusion; it was not obviously distensile, and pulsation was very slight. The brachial radial and ulnar pulses were absent. A fluctuating swelling was present along the anterior border of the deltoid. There were some signs of nerve contusion, but no paralysis, beyond tactile anaesthesia in the area of distribution of the median nerve. Four days later little alteration had been noticed beyond a tendency to variation in firmness of the different parts of the swelling. On the thirty-first day considerable enlargement was observed. This enlargement, together with continued rise of temperature, aroused the suspicion of suppuration, and an exploratory puncture with a von Graefe's knife was made by Major Lougheed, R.A.M.C., after consultation with Professor Chiene. Blood clot first escaped, followed by free arterial haemorrhage. The incision was enlarged while compression of the third part of the subclavian was maintained; a large quantity of clot was turned out, and an obliquely oval wound half an inch in long diameter was found in the axillary artery. Ligatures were applied above and below the opening between the converging heads of the median nerve. The veins were not damaged. The wound healed by first intention. On the twelfth day a feeble radial pulse was perceptible, and shortly afterwards the man left for England, diminished median tactile sensation being the only remnant of the original symptoms.
