THE LUMBAR CUllVK IN SOME AMERICAN RACES.

the sums of the anterior measurements of the five lum- 

 b.irs in the males is 124 mm., highest 138 mm , lowest 

 114 mm.; average for the females, 120 mm.; highest 

 126 mm., lowest 113 mm. The general average of the 

 sums of the posterior depths in the males is 130 mm., 

 highest 140 mm., lowest 119 mm. ; females, average 117 

 mm. ; highest 121 mm., lowest 110 mm. 



In addition to the nineteen skeletons from A neon 

 which were examined for the preparation of the above 

 table, there were twelve other skeletons which showed 

 marks of senility to such a degree as to necessitate a 

 separate treatment. In the preceding sections such 

 skeletons have not been sufficiently numerous to deserve 

 special notice, and they have consequently been excluded 

 along with the skeletons of children and partially grown 

 individuals- But it is believed that these nine Ancon 

 skeletons may throw some light on the changes produced 

 by old age on the lumbar curve.
