The Spinal Curvature in an Aboriginal Australian. 499 

 Four Irish Spines (two Males and two Females). 



In this table the indices of the intervertebral disks hare been calculated in the 

 same manner as those of the vertebral bodies. The anteripr vertical depth in each 

 case has been taken as the standard, and equal to 100. By multiplying the poste- 

 rior vertical diameter by 100 and dividing the result by the anterior vertical 

 diameter, the indices have been arrived at.

to the curve are the fourth and fifth. The indices of these are 286 

 and 38*4 respectively. 



The European spine which we have selected for comparison with 

 the Australian spine also presents a somewhat low lumbo-vertebral 

 index, viz., 91 '0. The intervertebral index is consequently higher
