The same index for the trochlea of our Anau talus on both sides amounts
to 79.4. The narrowing is therefore somewhat more pronounced than in adult
Europeans, but does not attain any exceptional degree.

On the other hand the Anau talus differs in another characteristic considerably,
not only from Europeans, but also from all other races concerning which we have
the results of investigations, viz, in the angle by which the axis of the neck and
head differs from the longitudinal axis of the trochlea (plate 96, fig. 2). For
this angle Volkov (1903, p. 706) gives the following values:

Negroes, males . . . . . . . . . . . . . . . . . . .24° | Eskimos, males. . . . . . . . . . . . . . . . . .21°
Melanesians, males. . . . . . . . . . . . . . .23.4° | Weddas, males. . . . . . . . . . . . . . . . . .20°
Negritos, males. . . . . . . . . . . . . . . . . .23° | Patagonians, males. . . . . . . . . . . . . .20°
Fuegians, males. . . . . . . . . . . . . . . . . .22° | Europeans, males. . . . . . . . . . . . . . .17.8°

In Anau I the deviation of the neck for both sides is 31°; it is therefore higher
than the average of any of the races enumerated. But even individual values
as high as this were found by Volkov only in new-born children, where he measured
angles up to 35°. The values given for Japanese up to 47° are clearly wrong,
since the mean is stated as 19° and the minimum as 28°. Still, Adachi found among
Japanese a mean of 19°, but individual variations up to 32°. Thus the Anau
talus takes an extreme position in this clearly primitive characteristic, only
Japanese occasionally showing as high a divergence.

The torsion of the head of the talus is important, because the transversal
arching of the foot is in part dependent on it. According to Volkov's investiga-
tions (1904, p. 320) its values form an increasing series:

New-born Europeans . . . . . . . . . . . .16.5° | Negroes. . . . . . . . . . . . . . . . . . . . . . .36°
Negritos. . . . . . . . . . . . . . . . . . . . . . . .34° | Japanese . . . . . . . . . . . . . . . . . . . . . .39°
Melanesians. . . . . . . . . . . . . . . . . . . . .35° | Europeans. . . . . . . . . . . . . . . . . . . . .49°

In the Anau talus the torsion is less than in any of the races investigated by
Volkov, 30° to 33°, and is therefore a primitive characteristic of high importance.

The calcaneus also shows peculiarities which differ from that of the European.
Its sustentaculum tali is very strongly developed; as Volkov has shown "the
lower races" form in this respect "a real transition between the foot of the anthro-
poids and the foot of the European." Plate 96, fig. 3, shows this difference.

Still another characteristic is to be seen in this figure, one that points to a
slight height of the arch of the foot. The joint-surface of the calcaneus intended
for the cuboid is more wide than high, and, looked at from below, is less visible
than in the European, because it stands more vertical in relation to the longitu-
dinal axis of the calcaneus. The wide, low form of this joint-surface is especially
striking in Anau I. We find in this a breadth-height index for both sides of 62.5,
while 5 Europeans gave a mean value of 92.0.

The anterior inner joint-surface for the talus on the left is divided into two
separate facets, while on the right these are connected by a narrow isthmus.

The right naviculare is very thick on its medial edge; on the lateral, on the other
hand, it is narrow. An index which we calculate, taking the thickness at the inner
edge as 100, amounts to 47.4. It is interesting to compare this with the figures
given by Volkov (1904, p. 38) as shown at top of next page.
