 plausible position of the head of the femur in the ace- 

 tabulum. The ridiculous articulation of the great tro- 

 chanter with the ischial peduncle demanded by Professor 

 Tornier, who seems to have mistaken the ischial peduncle 



for an anti-trochanter, has already been alluded to. Of 

 course we could not accomplish such an articulation, but 

 we have come as near to it as the bones will allow. 

 Placed as nearly as is possible in the situation in which
