On the other hand, it is difficult to believe that the length of the con- 
jugate diameter was not approximately definitive. 
In other words, the pelvis, as a whole, had nearly attained its definitive 
form when growth was reaccelerated. Because the triradiate cartilage was 
obliterated, this late growth could not affect the pelvis equally, but could 
only affect the lateral sacral, the pubic, the ischial, and the iliac epiphysial 
cartilages. Growth of these leads directly to increase in the breadth and 
height of the pelvis. The antero-posterior or conjugate diameter is 
unaffected by their activity. The evidence is definite that in this case the 
onset of anorchidism was late. 
In the shoulder-girdle the clavicle of A 10 is almost a facsimile of the 
clavicle of A 9. It is somewhat shorter, but the antero-posterior diameter 
of its sternal end is identical with the corresponding diameter in A 9’s 
clavicle, and the antero-posterior diameter of its acromial end is only one 
millimetre less than in the case of A 9. (See Table XV.) 
The clavicular epiphysis is almost entirely cartilaginous. 
The scapula of A 9, not including 7 mm. of cartilage along its vertebral 
border, is relatively much broader than the scapula of A 10 (see Table XYI.). 
Its measurements, including and not including the cartilage of the vertebral 
border, are given in Table XLVII.

Including the cartilage, which would have become bone had life been 
prolonged, the relative breadth of the bone is phenomenal. 
In the limb bones none of the epiphysial lines have quite disappeared, 
but they have all joined. In the region of the late closing epiphyses, more 
especially in that of the lower end of the femur, there is a marked broaden- 
ing of the bone, with a peculiar splay upon the lower end of the diaphysis, 
which suggests that there was an unusual amount of endochondral bone 
formation after the central part of the intermediate cartilage was obliterated. 
The measurements and comparisons of the bone lengths are given in 
Table XLVIII.
