The spacebetween the patella and tibia and behindthe ligamentum patella? was filled withcondensed adipose and fibrous vestiges remained of cartilage or synovial cut surface of the tibia presented its normal celhtlar texture,except a single large cell capable of holding a filbert near the outeredge of the bone and havhig for its upper wall the thin compactshell of the articular surface. The section of the patella was also. * In the Daguerreotype from which this was engraved, the figure was re-versed, which was not observed by the Editor until the engraving was finished. EXSECTION OH EXCISION OF THE ARTICULATIONS. 839 of normal cellular texture, with a similar large cell of three-eighthsby three-fourths of an inch in extent. A third and much largercell capable of containing a hickory init, occupied the inner condylenear its articular surface. These cells were lined with a thin red-dish membrane and contained an oily and fatty matter of reddishcolour. Another incomplete cell was also found in the outer con-dyle, intersected with septa, subdividing it into smaller compart-ments lined and filled like the rest; none of these cells perforatedthe outer shell of bone, though at some points they approached verynear it. Subsequent, long-continued maceration separated the severalparts from each other. Remarlis.—Though this operation was severe and protracted,the su
