The establishment of the fact that the presence of a pronounced 

 sulcus is a valuable indication of the sex of a given hipbone, led to 

 its constant employment in the work of the Nubian Archaeological 

 Survey, as a means of sexing skeletons when other indications were 

 absent, as in the case of bones with the pubic portion broken away, 

 or to assist the evidence derived from other parts of the skeleton, 

 when this was doubtful. 



At the same time dissections were undertaken to demonstrate the 

 condition in the recent subject and the writer was able to fully confirm 



Fig. 3. Left hip bone of a man from the collection of the Nubian Archaeological 

 Survey, illustrating an unusually well-developed masculine sulcus praeauricularis. The 

 ilio-sciatic notch is very deep and narrow. 



Zaaijer's statement that the sulcus gives attachment to the anterior 

 sacro-iliac ligaments, and to ligaments only. 



As a result of these and other observations the writer published 

 a paper in the Journal of Anatomy and Physiology, Vol. 43, 1909, 

 entitled "The determination of sex from the innominate bone, with 

 special reference to the sulcus praeauricularis". Prof. Hans Virchow 

 was not apparently aware of this as he does not refer to it in his 

 paper, nor yet to the work of Dr. Pipin Löhr who published the 

 results of his examination of a large number of hip bones in the 

 Anat. Anzeig., Bd. 9, 1894, p. 531.
