When admitted at Netley the patient came under the care of Major Dick, R.A.M.C., who ligatured the popliteal artery on the proximal side by an incision in the line of the tendon of the adductor magnus. The aneurism then consolidated. (7) _Traumatic popliteal aneurism._--Wounded at Magersfontein. _Entry_ (Mauser), centre of patella. _Exit_, centre of popliteal space; the knee was bent at the time it was struck. There was considerable primary external haemorrhage, and so much blood collected in the knee-joint that it was aspirated. On the eighth day secondary haemorrhage occurred from the exit wound and the femoral artery was tied in Hunter's canal. No further haemorrhage occurred, but at the end of three weeks feeble pulsation was palpable in the popliteal space, suggesting an aneurism; the latter decreased and the patient was sent home apparently well. (8) _Traumatic axillary aneurism._--Wounded at Karree. The bullet entered 2-1/2 inches below the acromial end of the right clavicle and emerged over the 9th rib in the posterior axillary line. The Mauser bullet was found in the patient's haversack. Both apertures were of the slit form, and healed per primam. Three weeks later at Wynberg a large arterial haematoma which pulsated was noted in the axilla. Signs of injury to the musculo-spiral nerve were also observed. The tumour altered little, but a fortnight later Major Burton, R.A.M.C., cut down upon it through the pectorals. The aneurism was of the third part of the axillary artery, and a ligature was applied at the lower margin of the pectoralis minor. The wound healed by primary union and the aneurism rapidly shrank. The patient left for England a month later; the musculo-spiral paralysis was improving. I am indebted to Major Burton for the notes of this case. (9) _Traumatic popliteal aneurism._--Wounded in Natal. _Entry_ (Mauser), immediately above head of fibula. _Exit_, immediately inside semi-tendinosus tendon at level of central popliteal crease. Fulness but no pulsation was noted at end of three weeks; seven days later pulsation was evident, and an aneurism the size of a pigeon's egg, with firm walls, became localised and palpable. It gave rise to no symptoms, and patient refused operation during the three weeks he remained in hospital. The aneurism continued to contract, and the patient was sent home. The aneurism has since spontaneously consolidated.
