WHOLE VOL. SKELETAL REMAINS OF EARLY MAN HRDLICKA 1 33 



All these features will be encountered, though probably not all in 

 the same specimen or to quite the same degree, on negro, old Egyptian, 

 and various recent tibiae, if there is ample material for comparison. 



The mild concavity from side to side above the tuberosity is due 

 to the pronounced development of what should be called the ilio-tibial 

 tubercle and facet, which serve for and are developed by the attach- 

 ment of the ilio-tibial fascia. The tubercle may be encountered with 

 varying frequency, and at times strongly developed, in the tibiae of 

 all races. Its pronounced development in the Rhodesian tibia indicates 

 merely an exceptionally strong development of the fascia and not a 

 phylogenetic peculiarity of the bone. 



Much the same may be said of the looping ridge. All its elements 

 are found in occasional late and recent tibiae, separately and even 

 combined. 



The inclination and other characteristics of the medial condyle and 

 of its articular facet are comprised in the above generalization. This 

 condyle shows moderate marginal exostoses which are evidence of 

 arthritis deformans, and that this disease is capable of modifying 

 the mesial facet in its inclination and other characters is well known. 

 The posterior border of the facet has been damaged, which influences 

 its aspect and makes it appear more inclined backwards than is 

 actually the case. But even thus the inclination backward of the con- 

 dyle and its facet can be matched and even exceeded in recent 

 bones. 



It would be useless in this place to go into detailed comparative 

 measurements and more minute descriptions ; it will suffice to repeat 

 that there is not one feature or dimension of the Rhodesian tibia 

 that may not be found also in the tibia of the tall African blacks and 

 other recent bones. There is no one among the 50 negro tibiae of both 

 sexes that were used for comparison that equals in all respects that 

 of the Broken Hill, but there is also not one of the negro bones that 

 is fully equalled by any of the others, each specimen having more or 

 less of individuality. 



The fibular facet, the conformation of and below the posterior 

 border of the upper surface, the size and shape of the shaft, the 

 popliteal ridge, nutritive foramen, the lower part of the shaft, the 

 maleolus, and the low^er articular facet, all are close to or identical 

 with corresponding features in individual negro and other mo<lern 

 bones. 



There is not a point here, as in the rest of the bone, that could 

 justly be designated as exceptionally primitive and belonging distinctly 

 to an earlier human estate. The bone, notwithstanding some indi-
