The proximal articular end has a transverse width of 5| 
inches as preserved, but about one inch appears to be lost from 
the inner articular extremity or articular ball of the bone. 
The proximal articular surface is obliquely truncated, for the 
inner half is convex and somewhat hemispherical, extending 
an inch further proximally than the outer part, which is 
flattened, though slightly convex from front to back. The 
thickness of the proximal end is about 2t inches. 
The middle of the shaft is about If inches thick. Its least 
transverse width is 2\ inches. It is ovate in section. The 
medullary cavity measures from an inch to an inch and a 
half wide, by three-quarters of an inch deep. 
The inner side of the bone is concave in length, and 
regularly convex from above downward and backward, 
supposing the femur to have been carried in a nearly horizontal 
position. The external side of the bone is at first convex from 
above downward near to the proximal end, and then it 
becomes flattened. Towards the proximal end its external 
lateral contour is distinctly convex, while in the greater part 
of the length of the shaft it is markedly concave. 
On the antero-superior surface of the bone, 2 f inches below 
the proximal cartilaginous articular surface was an elongated 
trochanter or ridge now broken away, but which does not 
appear to have been much elevated. Its base is fully four 
inches long, nearly straight, three-quarters of an inch wide, 
rounded at the proximal end, and narrowing distally to a 
point. It is parallel to the inner border of the bone, so that 
while its proximal end is about one and a half inch from the 
outer margin of the bone, its distal end is less than three- 
quarters of an inch from that margin. Its elevation makes 
the middle width of the bone, which is internal to it, to be 
longitudinally concave. As the line of the trochanter is 
followed down the shaft, it makes the outer side of the bone a 
little thicker than the inner side. 
The infero-posterior surface of the bone is flattened, and 
slightly concave from side to side. 
The distal end of the bone widens till it measures five and 
a half inches in transverse width; and the articulation is 
nearly four inches deep on the inner side, where the bone is
