The above comparison does not seem to bring out any- 

 thing definite as to whether certain types of pelvis accom- 

 pany certain forms of skull, and the number of instances is 

 too small to be of any value by themselves. They may 

 possibly assist others with more material at their disposal. 



Bones of the Limbs (Maoei). 

 The principal measurements of the limb-bones of thirteen 

 skeletons, nine of which are male and four female, are given 

 in Table VI. Few of these skeletons are sufficiently perfect 

 to allow of all the bones being measured, but I include in the 

 table all those which have allowed of any of the usual com- 

 parisons between bones of the same body being made. In the 

 text I give also the results of the measurements of numerous 

 other bones, none of which could be with certainty identified 

 as belonging to the same skeleton. 



Sca^nda. 

 The measurements were taken in the manner originally 

 proposed by Broca, and adopted by Flower, Garson, Turner, 

 and others. The length is the distance in a straight line 

 between the upper and the lower angles. The breadth is the 

 distance between the centre of the posterior margin of the 

 glenoid cavity and the point where a line drawn along the 

 attached margin of the spine w^ould cut the posterior border 

 of the bone. The infra-spinous length is the distance between 

 the last point and the inferior angle. The two indices are also 

 calculated in the usual way : —

 Twenty-five scapulae were sufficiently perfect to let me 

 make the above measurements ; of these, thirteen were right 

 bones, and twelve belonged to the left side. I have not 

 attempted to distinguish male and female bones, excepting in 

 the case of those included in the table, which belong to skele- 

 tons sufficiently perfect to allow of the sex being determined. 

 Though the number of undoubted female bones is too few to
