GARSON : HUMAN REMAINS FOUND AT HOWE HILL, DUGGLEBY. 235 
The height measurement and the height to length index are 
slightly less in the first group than in the second. The appearance 
of greater height imparted to the eye in the former is therefore due 
to the want of filling out of their lateral walls, and the acuteness of 
the arch formed by the upper and curved parts of the parietal bones, 
as it will be seen that there is little variation in the biauricular 
diameter in the whole series, except in L, which is unusually narrow 
in this region. Only in K does the height exceed the maximum 
breadth. Owing to the imperfect condition of the specimens it was 
not possible to measure the cranial capacity, but as estimated from 
the cephalic module of Schmidt it is a little larger in the second 
group than in the first, though the antero-posterior or sagittal, the 
horizontal, and the traverse circumferences of the cranium are 
practically similar in both groups. 
The narrowness of the cranium in the first group is not confined 
to the maximum breadth only, but extends to the minimum, and the 
maximum (bistephanic) diameters of the frontal bone, and also to 
the external biorbital and bizygomatic diameters, all of which are 
less than in the second group. This shows that the upper part of 
the face is quite in harmony with the width of the calvaria in each 
group. The minimum traverse diameter of the maxillary bones, 
that is, the maximum alveolar breadth, is if anything, less in the 
second group than in the first, while the bigonial diameter of the 
mandible averages 6 mm. less in the former, showing that the lower 
part of the face is narrower in them than in the latter, thus reversing 
the conditions present in the upper part of the cranium. This 
narrowing of the lo wer part of the face in the second group appears 
more accentuated on account of the greater breadth of the upper 
part, and gives a somewhat wedge-shaped appearance to the face. 
Details of the characters of the nose, orbits, &c, from the measure- 
ments is unfortunately impossible. 
The skulls are in all respects similar to those of Long Barrow 
specimens which have passed through my hands from different parts 
of the kingdom, but I have never examined a series of skulls in 
which there were such a large proportion of hyperdolichocephalic 
specimens. The two types found in this series I have long been 
familiar with among Long Barrow skulls. That which I have dis-
