ANTHROPOMETRIC CHARACTERS OF BEAVER, SEKANI,
AND CARRIER INDIANS

The following is a list of the measurements taken of the Beaver
Indians. Of the Sekani and Carrier Indians the seven measurements
marked with an asterisk were taken, and the four indices marked with an
asterisk are derived from them.

*Stature.
Sitting height.
*Length of head (glabella ad maximum).
*Width of head (biparietal maximum).
Width of forehead (frontal minimum).
Length of face—
*(a) Menton-nasion.
(b) Menton-crinion.
*Width of face (bizygomatic maximum).
*Height of nose.
*Width of nose.
Length of mouth.
Length of ear.
Width of ear.
Length of upper lip.
Length of hand.
Width of hand.

From these the following indices have been calculated:

Sitting height. (Sitting height to stature.)
*Cephalic. (Width of head to length of head.)
*Cephalo-facial. (Width of face to width of head.)
*Facial. Length of face (menton-nasion) to width of face.
*Nasal. (Width of nose to height of nose.)

Ear. (Width of ear to length of ear.)

Hand. (Width of hand to length of hand.)

The data on which this report is based and from which the various
tables have been compiled are set out in the appendices, pages 28 to 37, and
are, therefore, available to anyone who may wish to utilize them. The results
of the methods adopted in this section of the report are presented in their
most concise form in the following table, No. XII, in which, for purposes
of comparison, data on the Fond-du-Lac band of Chipewyan Indians
are included.

Anyone who would analyse the figures from which a particular mean
has been calculated should turn in the first place to the appropriate frequency
distribution table (pages 18 to 27) where he will find the mean, the standard
deviation, the probable error of the mean, the coefficient of variation,
and the precise number of cases examined, all duly recorded; and sub-
sequently, if he would pursue his inquiry, let him consult Tables XIII
and XIV which interpret Table XII and make the words of the text more
or less superfluous, for they tell us whether the intertribal differences,
which Table XII suggests exist, are genuine differences or merely apparent.
Table XIII deals with the males; Table XIV with the females. As an
example of the way in which to employ the probable error was given in
the first and second reports it is unnecessary to repeat it here.t
