The overall robusticity of the femoral diaphyses can be compared 

 to those of relatively large samples of European Mesolithic femora 

 using its midshaft external diameters [((AP x ML)" : / bicondylar 

 length) x 100]. The resultant indices are 6.6 and 6.2 for Gough's

 100) for Gough's Cave 1 and Mesolithic samples.

Cave 1 , the right one of which is on the means of Mesolithic (6.5 ± 

 0.4, N = 47 ) and Mesolithic male (6.6 ± 0.4, N = 3 1 ) samples and the 

 left one only slightly below them. In this, the large Muge sample has 

 a significantly (P = 0.002) lower mean (6.3 ± 0.2, N = 19), but its 

 inclusion or deletion from the Mesolithic sample has little effect on 

 the relative position of Gough's Cave 1. 



Using midshaft cross-sectional measures, the percent cortical 

 areas largely cluster close to the Mesolithic comparative means; only 

 the 80% one is relatively low, significantly so with respect to the 

 Mesolithic male sample (Table 9). Plots of the midshaft cortical area 

 and polar moment of area versus powers of femoral length (Fig. 9) 

 largely support the pattern seen in the robusticity indices; Gough's
