The Tibra. 
The length of the tibize, like that of the femora, averages slightly greater in the 
male skeletons from Arkansas than in those from Louisiana; as to the females, the 
bones from Arkansas are too few in number to be of value for comparison. The 
right tibia averages slightly longer than the left. The relation of the length of the 
tibia to that of the femur, z. e., the tibio-femoral index, which ranges in whites from 
about 80 to 81, is perceptibly greater in the skeletons under consideration, especially 
those from Louisiana. It is a curious local peculiarity that this index, in both 
males and females, is somewhat higher in Louisiana than in Arkansas. The sexual 
differences, as in whites, are quite immaterial; and nothing definite appears from 
the series as to differences on the two sides of the body. 
In addition to its length, the tibia was measured also as to its two principal
