the thickest, being formed hy the broad and flattened part of the great trochanter : 

 it gradually contracts to the emargination, where the femur offers its smallest 

 antero-posterior dimension, and is there almost thinned off' to an edge. In forming 

 the upper side of the terminal angle the outer margin enlarges to a thick convex 

 protuberance, which slightly overhangs by a well-defined concave ridge, the broad 

 shallow depression forming the outer side of the external condyle. The plane 

 of this depression forms the lower side of the terminal angle, and gives to the 

 distal end of the femur the appearance of having had its external angle obliquely 

 and abruptly truncated. The inner border of the femur is shghtly concave and 

 smooth below the head, then convex and rough where it defines the small tro- 

 chanter ; it next describes a wide and moderately deep concavity, bounding the 

 middle and part of the lower third of the shaft, and it terminates by falling rather 

 abruptly to the margin of the internal condyle, a projecting angle being thus 

 formed between this sloping surface and the preceding concavity : the margin of 

 the condyle, which terminates the inner boundary of the femur, shghtly projects. 

 The articular condyles, though contracted by the sloping in or convergence of the 

 outer and inner angles, are broader from right to left than from before backwards. 

 The rotular and tibial articulations form one continuous surface : the two trans- 

 versely convex parts of the surface for the patella are joined by a middle conca- 

 vity: the inner convex rotular surface projects more forwards, and rises higher 

 than the outer one, which, on the other hand, descends lower ; so that their 

 vertical diameter is alike. The tibial, or inferior and posterior parts of the con- 

 dyles, which are continued backwards from the rotular articulation, are sepa- , 

 rated from each other by a wide and deep depression. The inner condyle is 

 broader posteriorly, and rises higher upon the back part of the femur than the 

 outer one ; it also projects a little further back and maintains the same breadth 

 to its convex posterior termination. The outer condyle slightly contracts to the 

 same part, which is terminated by a more nearly straight transverse line. There 

 is a slight depression at the middle of the lower part of the anterior surface of 

 the femur, just above the middle of the bilobed rotular articulation : the posterior 

 projections of the condyles leave a deep and wide vertical concavity on the sur- 

 face of the femur above them, which is slightly convex from side to side. As 

 the head of the femur inclines a little forwards, and the condyles are bent back-
