Mr. John Hewitt, Director of the Albany Museum, very kindly took 
four excellent photographs of the skull, and I am much indebted to him for 
the pains that he expended. 
Features or the Sktjll. 
Norma Verticalis Phaenozygous. 
The whole of the frontal bone, from glabella to bregma, is visible. The 
glabella is prominent, forming, with the upper orbital margins, a bracket- 
shaped curve. 
In this view one also sees the whole of the zygoma, the whole lower 
margin of the orbit, the alveolar border of the upper jaw as far back as the 
first premolars ; both mastoid processes are visible. The temporal fossae 
are deeply indented. (In the photo the slight tilting of the specimen and 
the monocular vision of the camera yield slightly different results.) 
Norma lateralis. 
This shows well the extreme prognathism ; all the teeth are perfect, but 
the lower central incisors show some absorption of alveolus. 
Norma facialis. 
Yery little of the cranium is visible. 
Norma occipitalis. 
The supra-occipital portion of the occipital bone is very small. Below 
the inion the bone makes an acute angle with the horizon. 
Norma hasalis. 
The insignificance of the cranium is a marked feature. The mental 
tubercles are almost absent, being just perceptible to touch. 
Principal Measurements. 
Length of skull ........ 123 mm. 
Breadth of skull . . . . . . . . 86 „ 
Height above external auditory meatus . . . . 77 ,, 
This gives a cranial index of 69*9, or a marked degree of dolichocephaly, 
yet one which is exceeded by present-day Hottentots and Australian bush- 
men ; and an altitudinal index of 69*9 mm. (tapeinocephaly). 
Cranial capacity 340 c.c, i. e. equal to an infant of two weeks old. The 
capacity was repeatedly measured with Kafir corn seeds, well shaken down 
without ramming, and actually gives a reading less than some anthropoid, 
apes. 
Gorilla . ......... 557 c.cm. 
Chimpanzee . . . . . . . . . 427 ,, 
M. J 340 „ 
Baboon . 210 „ 
A list of more detailed measurements is appended.
