Mr. Boyd Dawkins has furnished me with the principal dimensions of several other _femora_, varying in length from 16 to 18 inches, and affording an average length of about 17, corresponding to a mean height of the individuals of about 5 ft. 4 in. to 5 ft. 5 in., the tallest being perhaps 5 ft. 6 in., and the shortest about 5 ft. 2 in., no doubt a woman. The mean perimetral index of the eight _femora_ is ·186, which shows, in comparison with the usual thickness of well-formed male thigh-bones of the present day, a certain degree of slenderness. That this is not altogether owing to the circumstance that the bones include those of perhaps more than one female is proved by the fact that in no instance does the perimetral index exceed ·192, and in one thigh-bone, 18″·2 long, it is not more, if the circumference is correctly given, than ·178, the normal perimetral index for the adult male _femur_ in this country being taken as about ·194. (d.) _Tibiæ._--Of the leg-bones brought under my notice, five are entire and five more or less defective. The principal dimensions and proportions of these bones, so far as they could be taken, are given in the subjoined Table.
