half preserved ; showing the effect of an old fracture. The fragments are bent to a right angle, and firmly united. Both are diseased ; and about the upper is an old periosteal deposit. At the seat of injury there is a large cavity in the interior, that seems as if it may have communicated with another external to the bone. From a young subject. 1847.

1115. Old fracture of the left femur, 4J in. from the lower ex- tremity ; lower portion of bone shown, and sawed longitu- dinally. Union strong, but very irregular, though not overlapping ; lower fragment drawn backward. Structure of the connecting bone seems to show that the accident could not have been an old one. In this connecting bone is a large cavity, smooth upon the inner surface, and look- ing as if it may have contained a piece of bone, or some foreigji body ; a small fragment of lead being seen near the opening from it. 1864.
1116. A portion of the femur, showing a comminuted fracture of the lower third ; the especial point of interest, being a contusion or breaking down of the cancelli of the outer condyle. Some appearance of absorption, and of an at- tempt at exfoliation. The fragments are united in their natural position. From a man who fell from the staging of a house, and lived six weeks. (Hospital, 79, 70.) 1859.

1117. Comminuted fracture, just above the condyles of the fe- mur. Union imperfect, and exceedingly irregular. Bones most remarkably atrophied ; the knee-joint being included in the preparation.
From a woman, between eighty and ninety years of age, and in whom many of the other bones were found broken. 1847. Dr. J. C. Warren.
1118. An oblique fracture, just above the condyles ; and a sec- ond, between these two, into the knee-joint. The upper fragment is drawn downward in front of, and 2 in. below, the knee-joint ; its pointed extremity being far advanced in the process of separation, and showing finely the contrast
