_Post-mortem appearances._ All the ventricles of the brain were dilated with serum, and there was a good deal of effusion into the arachnoid and pia mater. The viscera were perfectly healthy, except the heart and spleen: the latter was very large, and on pressing it, a large quantity of dirty red pulpy matter exuded. The lining membrane of the right auricle and ventricle, when washed, had a dark red hue. The femoral vein, just at the ingress of the saphæna, and the superficial vein in the back of the leg, had their coats much thickened, so as to cut like arteries. Their lining membrane was similar to that of the right cavity of the heart. When they were divided, purulent matter, mixed with thin light-coloured blood, escaped. The cellular tissue forming the sheath of the femoral vessels, and on the calf of the leg, shewed marks of recent inflammation; but there was no appearance of pus in these situations. None of the glands in the groin or ham were enlarged. The inferior vena cava appeared healthy. E. CASES OF PURULENT DEPOSITS, CONNECTED WITH INFLAMMATION OF THE VEINS AFTER DELIVERY, RECORDED BY DR. ROBERT LEE IN THE MED.-CHIR. TRANSACTIONS. CASE XXXV. Mrs. Mayhew, æt. 33, was delivered on the 2nd March 1829. On the 5th, there was a discharge of blood from the uterus. From the 6th to the 20th, she made no complaint of uneasiness in any region of the body, though her strength rapidly declined. The countenance was of a dusky yellow hue. The heat of the surface slightly increased; the respiration hurried, particularly on bodily exertion, and the pulse above 130, and feeble; the tongue pale and glossy, with loss of appetite. The lochial discharge had a peculiarly offensive smell. She died upon the 28th of March. _Post-mortem appearances._ When the uterus was laid open, there was found to be a portion of the placenta, about the size of a nutmeg, in a putrid state, adhering to its inner surface. The substance of the uterus, to the extent of an inch around this, was of a peculiarly dark colour, almost black, and as soft as a sponge. On cutting into it, about a teaspoonful of purulent matter escaped from the veins, and a small additional quantity was pressed out from them.... On opening the capsular ligament of the right knee-joint, about six ounces of thin purulent matter escaped, and the cartilages of the femur and tibia were extensively eroded. There was no appearance of inflammation, however, on the exterior of the capsular ligament. The right wrist was swollen, and the cellular membrane around it was unusually vascular, and infiltrated with serum.
