Limbs. — The bones of the upper limbs present, in a somewhat 

 marked degree, a difference in the length of corresponding bones on the 

 rio-ht and left sides, as will be seen by the accompanying table of meas- 

 urements. The difference between the lengths of the ulna and hume- 

 rus, though somewhat less than in the average, is, nevertheless, not 

 uncommon in European skeletons. The humerus is perforated at its 

 lower end, on one side by a very small opening, and on the other has 

 only a thin plate between the olecranon and coronoid fossas. Of seven 

 skeletons of pure negroes which we have examined, the humerus was 

 perforated on hoth sides in three, on one side in one, and on neither 

 side in three. 



The thigh-bones offered nothing unusual, either as to the shaft or 

 neck. The tibia3 are remarkable for their length in proportion to that 

 of the femora. When the two bones are placed side by side, the lower 

 ends of both on the same level, the tibia reaches as high as the middle 

 of the neck of the femur ; while in the skeleton of a European it only 

 reaches as far as the lesser trochanter. The upper end of the tibia is 

 quite small, and its protuberance scarcely rises above the surface : the 

 shaft forms an equilateral triangle ; and, instead of having the anterior 

 edo'e quite sharp and prominent as in Europeans, it is rounded. 



The OS calcis is more slender than in ordinary skeletons, and is par- 

 ticularly remarkable for having the tuberosity and neck only slightly 

 exceeding the rest of the bone in their vertical diameter.
