In 5864 ossification has not yet taken place between the first 

 and second parts of the mesosternum, nor between it and the manu- 

 brium, but is complete between the second and third part of the 

 mesosternum, indicating that the skeleton is that of a young adult. 

 In 5429 ossification is complete in the mesosternum and partial 

 between the mesosternum and manubrium, indicating an advanced 

 age. In 5864 the xiphisternum is ossified, but is not yet attached 

 to the body of the sternum. 5429 is much broader, heavier, and 

 thicker than 5864, as the following measurements show.

Vertebra. In the case of the vertebrae there are only two spines 

 available for study. The vertebrae of both are well developed as 

 to strength. In 5429 there are marginal exostoses, and the laminae 

 and spinous process of the fifth lumbar vertebra are separate, ar 

 ticulating with the proximal part of the arch. The same anomaly 

 has been noted in the fourth and fifth lumbar vertebrae of a specimen 

 from Smith sound described by Dr. Hrdlicka. In addition the 

 lateral spine on the right side of the second lumbar vertebra is 

 separate, and there is a facet present for its articulation. The 

 thirteenth thoracic vertebra is present in both specimens; and has 

 been described at length elsewhere (see Occurrence of an Extra 

 Vertebra in the Eskimo) . Except for this peculiarity 5864 is normal 

 in every way. 



The indices of the five lumbar vertebrae (taken according to 

 Cunningham) are as follows:
