418 PRINCIPAL SIR WM. TURNER ON 



pressed nasion ; the projecting parietal eminences ; the relations of length and breadth 

 which place the skull on the confines between the mesaticephali and the dolichocephali, 

 the height being less than the breadth ; the platyrhine nose ; the prognathic upper jaw ; 

 the marked phsenozygous projection of the zygomata ; the face moderately broad in 

 relation to the height ; the moderate degree of prominence of the nasal profile ; and 

 the small cranial capacity are features in which this skull corresponded with the 

 Tasmanians previously examined, and from their importance when collectively present, 

 in the determination of race characters, leave no doubt that this skull from the Brussels 

 Museum is a good example of an aboriginal Tasmanian. We can proceed, therefore, 

 with confidence to study the other bones of the skeleton, to enable us to determine if 

 they also possess racial characters. In this connection it is interesting to note that 

 the Brussels skeleton, the male No. 1 761 1, originally in the collection of Barnard 

 Davis, and the male and female skeletons in the Hunterian Museum of the Royal 

 College of Surgeons of England, were also collected by Mr Morton Allport in 1872. 

 Of these, two males were from a cemetery in Flinders Island where the natives were 

 interned, and one, No. 1097, a woman who was moved from Flinders Island to Oyster 

 Cove, d'Entrecasteaux Channel, where she died in 1867 ; possibly the other skeleton 

 was also obtained by Allport from the same island. 



Hyoid. — This bone consisted of a body and a pair of great cornua. The posterior 

 surface of the body was concave and smooth ; the anterior surface was convex, rough, 

 with a short spine projecting forwards from its middle. The body was 16 mm. wide and 

 9 mm. deep ; each great cornu was 29 mm. long. The small cornua were not present. 



Sagittal Contour. 



In Part I. of my memoir on Tasmanian skulls, I figured tracings obtained with 

 Lissauer's diagraph of the sagittal contour of six male skulls, and I gave a series of 

 measurements of radii taken from the basion to definite points on the surface of each 

 skull. These radii were bisected by a line drawn through the nasio-tentorial plane, so 

 as to indicate the proportion of the cranial cavity occupied by the cerebrum, and that of 

 the basal region in which the cerebellum, pons, and medulla are lodged. I selected the 

 nasio-tentorial plane in preference to the glabello-inial plane, for it gave a more 

 definite conception of the division of the cranial cavity into a cerebral and a non-cerebral 

 space ; also because the nasion is a more definite point on the surface of the skull than 

 the glabella, which varies so much in form and degree of projection. I have made 

 similar measurements of the skull of the Brussels skeleton, and I record them in 

 Table II., alongside a column in which the mean measurements of six male Tasmanian 

 skulls in Part I. are given : —
