and in one axis the tip of the odontoid process had evidently 

 rubbed against the anterior edge of the foramen magnum. 



Dorsal Vertebra. 



The mean dorso-vertebral index of the three columns 

 which allowed of the necessary measurements being taken is 

 106-4. 



In one column the twelfth dorsal vertebra has no costal 

 facet on either side of its body, and those on the eleventh are 

 very small. One of the tenth vertebrae has no costo-trausverse 

 articulations, while in another there is none on the left side. 



Lumhar Vertebra. 



The average lumbo-vertebral index of the four sets of 

 lumbar vertebrae is 104-7. The highest index, that of a male, 

 is 113-7 ; the lowest, also a male, is 100. The mean of the 

 three males is 106. The female has an index of 100-7. In 

 two of the males, therefore, the sum of the posterior depths of 

 the bodies is greater than the sum of the anterior depths ; in 

 one they are equal ; while in the female there is a very slight 

 excess of the posterior depth over the anterior. 



The means of the indices of the individual vertebras is as 

 follows : — 



Three vertebrae, therefore — the first, the second, and the 

 third — are deeper behind than in front, taking the average of 

 the four sets of vertebrae. The following table shows the form 

 of the individual vertebrae in this respect : — 



Pelvis (Mobiori). 



The measurements of three pelves are given in Table V. 

 Two of these are male, one is female.
