Medina in his «Aborigines of Chile’ mentions several skulls 
to which he ascribes considerable antiquity, giving tfie following 
details.

These measurements in as far as they go would seem to inlicate 
that they might belong to the same race. 
The same author also gives some measurements of a Fuegian 
skull. 
Cephalic index 73, zygomatic diameter 130 mm. frontal 
minimum 82 mm. 
An ancient Tehuelche skull now in my possession, gives similar 
measurements but also differs in some respects. 
Cephalic index 74.7 length height index 73.7, breadth height 
index 98.6; mixed height index 86.1; orbital index 90.2; nasal 
index 55.5; facial index (Breca) 59.2; facial index (Kollmann) 
52.6; stephanic index 85.; capacity 1540. 
This skull is slightly prognathic; the glabella and supraorbital 
ridges very salient and massive; the nasal notch deep, and the 
bones of this organ both broad and prominent. The skull is 
slightly scaphocephale and presents the flattened planes menti- 
oned as common in the Serena skulls; the mastoids are small 
and the foramen magnum is pyriform. The torus occipitalis, 
strongly marked reaches from one asterion to the other. The 
double supraorbital noth is present, but the infraorbital suture 
in pars facialis is not noticeable, in fact all the sutures are more 
or less synostosed. Its general characters are dolicho-hypsi- 
akrocephalic and slightly scaphocephalic. 
From these details it will be seen that there is a great general 
resemblance among the prehistoric races of the soulthern extre- 
mity of the continent, and that their resemblance extends te the 
races inhabiting the Magellan Strait district; as well as to the 
Esquimaux who inhabit the extrem north. At the same time 
we hnow of no other race who have any near affinities with this 
type.
