5. The nasion -inion -opisthion angle. Also recorded by Berry and 
Robertson, as the opisthion angle, based on the glabella-inion plane. 
6. The total frontal arc. Nasion to bregma. 
7. The total frontal chord. Nasion to bregma. 
8. The length of the greatest distance of the arc from the chord. 
9. The length of the total occipital arc. Lambda to opisthion. 
10. The occipital angle, enclosed by the lambda-inion and the inion- 
opisthion chords. 
11. The length of the inion-opisthion chord. 
12. The total sagittal curvature. 
13. The total longitudinal circumference. 
14. The length of the vertical transverse arc. 
15. The length of the basal transverse diameter. 
16. The length of the total vertical transverse diameter. 
17. The length of the preauricular curve. 
18. The length of the postauricular curve. 
19. The length of the total horizontal circumference. 
In Table I. the individual and generalised observations just referred to 
of fifty-two Tasmanian crania have been set forth. The probable sex, 
the serial number, the present location, and the original number of each 
skull are set forth in the four upper horizontal lines. In the two vertical 
columns on the left, the numbers and names of the observations recorded, 
and the nature of the observation, are set forth. In the vertical columns 
1 to 52, inclusive, are set forth the individual measurements of each skull. 
The male and female cranial observations have been recorded in separate 
columns. The four vertical columns immediately on the right of the male 
observations record the number of observations made, the average figures 
for each observation together with the minimum and maximum figures 
for that observation. The four vertical columns immediately on the right 
of the female observations record like results, and for both sexes combined 
the figures are set forth in the four vertical columns on the extreme right 
of the Table. 
No. 48 has been shown to be a juvenile subject; all the observations 
recorded upon it have been uniformly omitted from the final results. 
For the purposes of determining the range of variation of each observa- 
tion, the minimum and maximum figures are denoted by means of a 
— or + sign. 
Of the observations set forth in Table I., 4 and 5 and 8 to 12 are 
original ; Nos. 13-19 are the original observations already referred to ; 
Nos. 3, 6, and 7 have already been published by Berry and Robertson
