In the month of December 1756. John Yates, aged 35 years, received an hurt upon and about his knee, by falling upon the ground from a man's back. The accident was immediately followed with a considerable degree of lameness and pain; which upon standing or walking were greatly increased.

He continued in much the same state for about six weeks after the accident. At the end of this time, the calf or the leg was attacked with an œdematous or doughy swelling; which, in a fortnight, became so painful, as to disable him from walking. The tumor continued to increase for about eight weeks; and at length extended itself so far upwards, as to affect the greatest part of the thigh, the whole of which was attended with excessive pain, but more particularly so about the knee.

N. B. So far I relate from the patient's own account.

On the 28th of April 1757. he was admitted into Guy's Hospital under my care.

Upon examination, the thigh appeared enlarged to a very great size. The tumor was uniform, and extended from the inside of the knee to within a very small space of the groin. The integuments were in every part of their natural colour.

Upon pressing the tumor on the inside, it appeared soft, and there was a very evident fluctuation to be felt on its internal and lateral part; but there was not the least appearance of pulsation.

The tumor, on its superior and posterior parts, was of a stony hardness.

The leg, which, according to the patient's account, had some time ago been much swelled, did not now appear to be at all so.

He was continually in great pain, and had been for some time incapable of getting any sleep. His appetite was bad. He was a good deal emaciated. He had a constant slow fever, which arose about five weeks before his admission into the hospital. He appeared pale and sallow in his complexion.

From the time of his being placed under my care to the end of ten days, there was no alteration in the swelling, or in the symptoms attending it.
