A comparison of these tracings and of the measurements in Table III. may be made 

 with the figures 1-10 in plates vi., vii. of my "Challenger" Report, 1884, in which 

 Australians, an Admiralty [slander, other Oceanic crania, etc. are represented, and with 

 table xviii. (p. 120) in which the radial measurements are given ; also with my memoirs 

 on the Craniology of the People of Scotland, pi. v. figs. 21-26, and table xvii., p. 609 ; 

 the Craniology of the People of India, part ii., p. 128, and part iii., pp. 303, 308 ; the 

 Craniology of the People of Borneo and other parts of Malaya, pi. xlv. figs. 27-29, and 

 table iv.,p. 806. 



Owing to the contour tracings being on the outer surface of the vault, the length of 

 the cerebral cavity cannot be stated precisely, as in two previous memoirs, when sagittal 

 sections were reproduced, but the distance from the perpendicular radius to the frontal 

 and the occipital points affords an indication of its long diameter ; neither can the height 

 of the cavity estimated by the collective tentorio-bregmatic, -perpendicular, -lambdal, 

 and -occipital diameters be precisely given ; but, subject to the deduction of five or six 

 millimetres, representing the thickness of the skull, from each diameter, the figures given 

 in Table III. express approximately the length and height of the cerebral cavity. The 

 greatest breadth of the cavity, although not capable of being measured in an antero- 

 posterior contour tracing, may, subject to a deduction for the thickness of the skull, be 

 estimated from the parieto-squamous diameter. By adding this diameter to those of 

 the four diameters taken from the tentorial plane to the points specified on the surface
