foss^ and by the form of tlie occipital part of the skull, which 

 in the Negro is more globular. Viewed from above, well cha- 

 racterised Negro heads appear more simious than the Engis 

 skull. 



" The front view," says Huxley, " shows that the roof of the 

 skull was very elegantly and regularly arched, and that the 

 greatest transverse diameter was a little less below the parietal 

 protuberances, than above them. The forehead cannot be 

 called narrow in relation to the rest of the skull, nor can it 

 be called a retreating forehead. On the contrary, the antero- 

 posterior contour of the skull is well arched, so that the distance 

 along that contour, from the nasal depression to the occipital 

 protuberance, measures about 13" 75 inches. The transverse 

 arc of the skull, measured from one auditory foramen to the 

 other, across the middle of the sagittal suture, is about 

 thirteen inches. The sagittal suture itself is 5'5 inches long. 



"The supraciliary prominences or brow -bridges are well, 

 but not excessively, developed, and are separated by a median 

 depression. Their principal elevation is disposed so obliquely, 

 that I judge them to be due to large frontal sinuses. 



" If a line be drawn, joining the glabella with the occipital 

 protuberance, no part of the occipital region projects more than 

 one-tenth of an inch behind the posterior extremity of that 

 line, and the upper edge of the auditory foramen is almost in 

 contact with a Hne drawn parallel with this upon the outer sur- 

 face of the skull. A transverse line drawn from one auditory 

 foramen to the other, traverses, as usual, the fore part of the 

 occipital foramen. The capacity of the interior of this frag- 

 mentary skull has not yet been ascertained." 



Thus far Huxley ; to whose description I would add, that 

 assuming the line from the occipital protuberance to the gla- 

 bella to be horizontal, the cranium is so arched that its greatest 

 height would fall behind a pei'pendicular drawn upon it, through 

 the meatus auditurius, and that the slight vaulting of the oc- 

 ciput, as well as low position of its protuberance, give it a 

 significant character. Though not a very striking occurrence 

 in civilised skulls, it is so in the skull of a savage, to find the 

 muscular lines and ridges so httle developed, especially when
