Only in No. 15,967 is the pelvis sufficiently well preserved to yield 
satisfactory measurements and, even in this case, some of the dimensions 
can be given only approximately, as, for example, the breadth of the 
iliac plate.

Nearly all the femora are more or less damaged, in consequence of 
which measuring is difficult, but the subjoined table will suffice to show 
the more important variations in size and proportions.
