With the object of combining the foregoing results in a graphic manner 
we have devised Table XXIX., in which the figs. 1 to 27 in the upper 
horizontal line correspond to those in Table XXVIII., and indicate the 
number of observations recorded by us upon the Tasmanian crania together 
with the comparative data derived from other sources : thus column 1 
indicates the glabella-inion length, column 2 the calvarial height, and 
so on. 
The left-hand vertical column in Table XXIX. is numbered from 1 to 
14 in an ascending scale from below upwards. These numbers indicate the 
evolutionary order of the objects compared : thus in vertical column 1 the 
gorilla occupies the lowest place numbered 1, with a lowest glabella-inion 
length of 147. In this column, on the assumption that marked length of 
skull with dolichocephaly is a primitive characteristic, the figures are 
arranged in an ascending scale from the nearest anthropoid — the gorilla — 
to the maximum, 202, in the Cro-Magnon cranium, and thereafter in a 
diminishing scale to the fourteenth place, occupied by the Kalmuck, 
with a glabella-inion length of 166 - 2. As such an arrangement is 
purely hypothetical, these figures are very properly omitted from the 
final results obtained by Mr Cross, and which are set forth in his paper, 
which follows. 
In column 2, which indicates the calvarial height-length, there is a 
marked interchange of position as compared with the positions occupied in 
column 1. These several changes of position can be noted by simply 
following the lines which connect the objects together : thus the Tasmanian 
drops from the tenth place in column 1 to the eighth place in column 2. 
The Cannstatt skull has the greatest calvarial height of any of the 
compared crania, and rises from the ninth place in column 1 to the 
fourteenth or top place as regards calvarial height in column 2. The 
anthropoid ape and Pithecanthropus alone retain the same positions. 
Of the several changes in evolutionary position, only one or two of the 
more interesting and instructive results need any reference. 
The position of the nearest anthropoid ape is instructive. In fifteen out 
of a possible twenty-four observations the ape occupies the lowest position. 
In seven observations the ape is in the second position ; and in one instance, 
column 12, the distance of the bregma foot-point from the glabella, he 
occupies the fourth position, that is to say, the bregma foot-point is farther 
forwards in the chimpanzee than in the crania of Pithecanthropus erectus , 
Brtix, or Spy-Neanderthal. 
In column 9, the distance of the calvarial height foot-point from the 
glabella, the ape actually occupies the highest position of all ; which implies
