Macalister — On the Osteology of two Negroes.

The sacrum, is short and curved, somewhat like that of a small 

 female, and the first rib articulated with the seventh cei'vical on the 

 left. The atlas has a complete (left) and an incomplete (right) bridge 

 on the posterior arch over the vertebral artery. 



IS'o. 2 is a much more massive skeleton, with two small ribs on the 

 first lumbar vertebrae, a perfectly detached first sacral vertebrae ; the 

 sacrum with a strong downly-directed spur on its lower left side. 

 The ossa innominata were enormously solid ; when dried, one weighed 

 lib., the other fib. All the bones have their crests much exagge- 

 rated. 



The femur has a strong supra-condyloid spur ; the calcaneum pro- 

 jects an inch and three-quarters behind the tibia. 



The humeri are very much flattened at their lower end, and the 

 forearm bones are markedly unsymmetrical on the two sides. 



The special points of interest in these two skeletons are : 1st, their 

 respective intermembral lengths ; 2nd, their general cranial charac- 

 ters.
