skeletons. As the Quichuas of the Cuzco region are 

 taller than the coast Peruvians, we may expect an increase 

 in the anterior and posterior lengths of the lumbar spine. 

 In the males, the average anterior length is 133 mm., 

 posterior, 135 mm. in the females, the anterior length is 

 121 mm., posterior 119 mm. Averages for both sexes 

 are, anterior and posterior, 127 mm. 



Summary. 



From the fact that the length of lumbar region of the 

 spine is a fairly reliable factor in computing the height 

 of the skeleton, I have summed up in one table the 

 average of the sums of the anterior measurements of the 

 five lumbar vertebrae for both sexes, and have arranged the 

 table in a serial order beg-inning; with the longest lumbar 

 spine.

If this table shows nothing else, it at least explains 

 what is already pretty generally known and that is that 

 the ancient inhabitants of the Ohio Valley were very tall
