Mr Shrubsall, Crania from Teneriffe. [May 11, 



the olecranon fossa was frequently perforated (in 23 per cent, of 

 the bones examined). The average maximum length was in the 

 male 323 mm. and in the female 304 mm. 



The radius and ulna were in most cases strongly marked, but 

 presented no special features of interest. 



Average length, radius male 247 mm., female 232 mm., but, 

 however, very few examples were measured of the forearm bones 

 of the latter sex. 



Ulna. Male 265 mm., female 243 mm. 



The femora were large and strong, deeply marked by muscular 

 impressions and often pilastered. The average length in the 

 oblique position with both condyles touching the lower end of the 

 measuring apparatus was for males 424mm. and for females 414mm. 



The tibiae were strong and in some instances platycnemic, the 

 average length being for males 365 mm. and for females 335 mm. 

 The jibidae, which were deeply channelled, were of the mean 

 length of 352 mm. in the case of the male and 331 mm. in that 

 of the female bones. Calculating the height of the former living 

 inhabitants from these measurements by means of M. Manouvrier's 

 sliding scale it is found to have been 1642 mm. for the males and 

 1552 mm. for the females. The results from each series of bones 

 is shewn in the subjoined table. 



Calculated height of living individual in millimetres : 



giving a mean sexual difference of 90 mm. 



Comparing the mean obtained for Teneriffe with the heights 

 arrived at by Manouvrier's scale for the races with which the 

 crania were compared, we have 



Teneriffe, 1642, 



Cromagnon, 1750, 



L'Homme Mort, 1620, 



Grotte de Laugerie, 1650.
