result is that the ihac crest is almost confounded with the 

 inferior and superior borders of the ihum. The two dia- 

 meters referred to above are almost equal (Fig. 50). 



We draw particular attention to what we have just 

 noted in regard to the transverse proportions of the 

 iliac and ischiatic regions of the dog and the cat. These 

 relations are evidently of importance with regard to shape, 

 since the iliac crests and the ischia are noticeable beneath the 

 skin. 



In the dog, the shaft of the femur is slightly convex in 

 front ; but in the cat it is straight. The borders of the shaft 

 are slightly marked, so that it is almost cylindrical. The linea

aspera, less prominent than in man, gains in width what it 

 loses in elevation ; it constitutes what may almost be called 

 a rough surface. This surface is narrower in its middle 

 portion than at its extremities, where it bifurcates to go 

 upwards to the two trochanters, and downwards to the two 

 condyles. At the superior extremity, the neck is short, the 

 great trochanter reaching almost to the level of the head of 

 the femur ; the digital cavity, which is situated on the in- 

 ternal surface of the great trochanter, is very deep. At its 

 inferior extremity it projects strongly backward. The 

 trochlea is narrow ; in the cat its two lips are equally pro- 

 minent, while in the dog the external is a little more elevated
