ETHNOLOGY. 



of a purplish color ; remarkable both for the absence of animal matter 

 and for the presence of the acid phosphate of lime. Unfortunately, no 

 analysis of these changed bones is given. 



Table No. 1. — The plan of this table is taken from Foster's work on 

 the prehistoric races of the United States, and the letters at the heads 

 of the columns refer to the same measurements. Four other columns are, 

 however, added, the first giving the capacities in cubic inches ; an im- 

 portant point omitted by Foster, probably from the Iragmentary nature 

 of the skulls in his possession. The second and third added columns 

 give the distance of the occipital protuberance from the posterior mar- 

 gin of the forainen mmjnum and the ratio of this distance to the long 

 diameter of the skull. This is an important characteristic of the mound- 

 builder race, according to J)r. Wyman. 



The fourth and last column gives the major and minor axes of thd 

 foramen magnum in millimeters.

*A. The horizontal circumference in the plane of a lino joining the glabella with the occipital pro- 

 tuberance. 



■•B. The longitudinal arc from the nasal depression along the middle line of the skull to the occipital 

 tuberosity. 



•(". From the level of the glabello-occipital line on each side, across the middle of the sagittal suture 

 to the same point on the opposite side. 



'1). The vertical height from the glabello-occipitalliue. 



*E. The extreme longitudinal measurement. 



*F. The extreme transverse measurement. 



Table No. 2. — In this table an attempt is made (by means of another 

 table of the comparative lengths of the various long bones in a series 

 of skeletons, given in Orfila's Exhumations Juridiques) to arrive at
