This skull and the one next to be described (Flixton Wold, Ixxi. 5) 

 belong respectively to a young man and a young woman of the 

 brachy-cephalic type, and of about the same age, viz. from 20 to 24 

 years of age, the age and the sex both having been determined by an 

 examination of the trunk and limbs as well as of the cranial bones. 

 They may be taken therefore as good illustrations of the form of the 

 brachy-cephalic type in early maturity, as the skull Heslerton Wold, 

 p. 598, may be taken to illustrate this type in the earlier portion of 

 middle life ; the skulls ' Ilderton,' ' Cowlam, lix. 3,' and ' Rud- 

 stone, Ixiii. 9,' its form in the later periods of middle age ; and ' Castle 

 Carrock, ccxiii. 1,' its peculiarities as modified by senile changes. 



The owner of this skull must have been a young man of very 

 great muscular strength, the femur being flanged out into a large 

 flat process anteriorly to the upper part of the insertion of the 

 glutseus maximus, and the linea aspera attaining similarly large 

 proportions, though traces of the anchyloses of its head and epi- 

 physes are still visible. It may be remarked that Dr. Holder, in
