18 Dr Duckworth, On the Anthropometric data collected 
The nasal length (Minikoi) is distinctly smaller than in the Addu 
group and other Maldivian islands, of which the various subgroups 
are not distinguishable. The nasal width is distinctly least im the 
Minikoi group, greatest in the Addu men and in the remainder it 
is intermediate. With regard to the nasal index, the Minikoi men 
are disposed in equal forces above and below the mean, while 
the Maldivian group (which is not subdivisible) shews a distinct 
tendency to excess on the side of the narrow noses. ‘The seriation 
of these nasal characters yields some rather interesting con- 
clusions. 
(f) Facial dimensions (upper facial length, facial width) and 
facial index. The Minikoi men have the shortest and narrowest 
faces: the Addu men have much longer but also broader faces. 
Moreover the Addu men are shewn by the facial index to have 
relatively broader faces than the Minikoi men. The other Mal- 
divian groups are intermediate between the Addu men and the 
Minikoi islanders. 
5. The various conclusions set out in Section 4, may be still 
further summarised as follows: 
(a) The Minikoi men are distinctly contrasted with the 
Addu men in eleven out of the twelve characters available for 
study. The exception is the head-breadth, ae. the absolute 
dimension of that name. Of the Maldive islands, Addu atoll is 
the most remote from Minikoi. 
(b) The remaining groups are intermediate between the 
Minikoi men and the Addu men in nine out of twelve characters. 
(c) The Minikoi men are distinctly contrasted with the 
“remainder” (7.e. Maldive groups excepting the Addu men) in . 
three out of the twelve characters. 
(d) From such investigations it is fair to conclude that the 
Minikoi islanders really offer distinct points of contrast with the 
islanders of the Maldive group. In section 3 (swpra) we have 
seen that the Minikoi men are more variable than the Maldive 
islanders. That they should be thus more variable is perhaps 
intelligible in view of their geographical position as compared 
with that of the Maldivians. This matter will be discussed a little 
further in the sequel. 
6. The standard deviation and coefficient of variability have 
been determined by me for a series of some ten characters or so, 
and these are set forth in the accompanying table : 
Only two remarks need be made in the present connection. 
First, the greater variability of the Minikoi men is (on the balance) 
confirmed. In the second place, the exclusion of the curiously 
formed head of No. 10 (Minikoi) has singularly little effect on the 
values of the means and other determinations. 
7. The variability of these islanders has now to be compared
