Icelanders Nonveginns
Breadth of shoulders (a—a) 22,5 22,3
Breadth of pelvis (ie—ic) 16,6 16,6
Circumference of chest 50,1 50,5
Cirumference of waist 43,4 43,9
These measures are verjT similar. The greatest difference
is as regards the cireumference of the waist and the breadth
of the shoulders. Thougli the Icelanders are more broadshould-
ered, they have a narrower waist
The difference of the circumference of the thorax is probably
rather an effect of different materials than a real one, and
very likely tlie difference of tlie minimum circumference of
the waist too.
The breadth index of the trunk (bicristal diameter: biacromi-
al diameter) was in Icelanders 74,0, in Norwegians 74,8. This
index is rather low in Icelanders, the European mean being
75,0, an effect of comparatively great breadth of the slioulders.
It may be said without exaggeration that all the principal
measures of the trunk are practically indentical in Icelandex-s
and Norwegians.
3. Measurements o'f the extremities.
a) The relative measui’ements of the u p p e r e x t r e m-
i t i e s were the following:
Icel. Norweg.
Length of the upper arm 19,2 18,9
— — — forearm 14,7 14,7
— — — hand 11,0 11,1
Total length of arm (sum of components) 45,0 44,7
—- — —arm (a-nda) 44,4 44,2
The absolute difference of tlie total length of the ann is only
3-—4 mm and quite insignificant because the acromion point
is by no rneans easy to locate exactly.
The difference of the length of the upper ann is the rnost
considerable, but it may be caused by a somewhat different
location of the aci’omion. The brachialindex, calculated from
the means above, is consequently 76,8 in Icelanders and 78,15
in Norwegians, but the difference is somewhat greater when
the total materials of the author and Halfdan Bryn are taken
into consideration (Icel. 76,55, Norwegians 78,9).
The t r u n k - a r m i n d e x (tolal length of the arm: height
of the trunk i.e. sy-sst) is in Icelanders 152,8, in Norwegians
148,0, calculated from the means above. For men 20—40 ys.
it was only 152,2.
