ETHNOLOGY, 285 
a half ;" or, finally, the owner of this skull may really 
have been a cross between a white man and a female of 
the Bushman stock. To this last explanation I myself 
incline. 
As regards the condition of the teeth, the skull 
presented by Mr. Fairclough, though referred by me to a 
man in the middle period of life, has only some seven or 
eight teeth, comparatively little worn, left in situ; the 
rest have been lost, and traces of two or three large alveo- 
lar abscesses, and great absorption elsewhere of the alveo- 
lar processes are very evident. Alveolar abscesses have 
similarly left their traces in the skull presented by Dr. 
Bleek, in which, however, the teeth have been very much 
worn down, though only one or two have been lost during 
life. The skull presented by Mr. Dunsterville had lost 
all its teeth, save the two central incisors, during life, and 
the alveolar processes have suffered a very large amount 
of absorption in this senile skull. 
Of the entire series, as the figures giving the length of 
the circumference and the cubic capacity show most 
plainly, we can predicate smallness ; the average of the 
latter measurement being but 1285 as against 1485 cub. 
cent, obtained by Professor Flower for the cubage of seven 
Caffres and Zulus, and, indeed, as against 1330 from his 
measurement of his available Bushman crania. 
With this small capacity is combined, which is by no 
means always the case in crania of races low in the scale 
of human life, a short basi-cranial axis, with an average 
length of no more than 93 millimetres. 
In none of these six skulls is the patency of the 
frontal suture, which corresponds very usually to a wide 
receptacle for the frontal lobes of the brain, observable. On 
the other hand, the zygomata do not come into view, when 
the skull is held out so as to present its norma verticalis 
at arm's length to one eye of the observer, with the in- 
variability which might have been expected. In two only 
. of these six skulls are both zygomata seen at the same 
time when the skull is held in this position ; in three the
