is somewhat flattened; transverse diameter, 2.6; antero-posterior 

 diameter, 1.3 cm. [At middle the shaft is intermediary in shape 

 between prismatic and plano-convex.] The lower third of the shaft 

 approaches cylindrical. Near the nutrient foramen is an exostosis 

 II mm. high, probably of traumatic origin. 



The left humerus [upper |] is much more slender, except in its 

 lower extremity, which equals that of the right bone. The shaft in 

 its upper third is near lozenge-shaped (on a cross section) [in the 

 middle region prismatic]. Maximum transverse diameter, 2.1 ; antero- 

 posterior diameter, 1.5 cm. Notwithstanding the slenderness of the 

 bone, the muscular insertions are well marked [though not correspond- 

 ing closely with those on the right bone]. 



The thickness of the walls is about the same in the two humeri ; 

 but the medullary canal of the left is much smaller (r. 13, 1. 8 mm. 

 in largest diameter). The transverse diameter of the lower end on 

 the right is 6.3 cm., and on the whole, near in its characteristics to 

 that of recent humeri. The olecranon fossa, however, as in other 

 Neanderthalers is deep and spacious (2.9 broad, 2.2 high, and at 

 least 1.3 cm. deep). The septum in the right humerus was not perfo- 

 rated, in the left shows a small aperture. The lower portion of the left 

 humerus resembles that of the right. 



Ulnae. — Present, right to olecranon only. The articular facets are 

 relatively flat. The jX)sterior surface indicates a strong triceps. 



Femora. — The shaft of the left femur is nearly entire but epiphyses 

 are wanting ; of the right femur only about one-half of the bone 

 (upper part) remains. 



[In strength, size and other characters the bones approach closely 

 a good modern medium male.]

The later index shows that there was but moderate flattening. 

 About its middle the shaft approaches cylindrical, with the linea 

 aspera but slightly developed. The popliteal region is wanting. The 

 whole shaft is moderately arched forward, resembling thus the other 

 Neanderthal femora. There is no hypotrochanteric fossa. What
