It appears from the above table, as regards the length and width relation of
the crown of the molars, which according to Frank and Wilckens is so characteris-
tic, that in all the compared horse teeth the length exceeds the width in premolars
2 and 3, and molars 3 and 2, and only equals the width in premolar 4 and molar
1, or is shorter. Only on a skull from Yana River in Siberia do I find somewhat
shorter teeth, in which the width is therefore relatively greater. This would
be an indication that the horse of the Anau kurgan belonged to the Western race.

If, now, we compare the relations under Tscherski's method and their results,
we find that the highest value for the projecting of the internal lobule belongs
to the Anau horse, the Siberian horse, Equus onager and Equus hemionus.

We have here in the especially demonstrative premolar 3 = 121, premolar
4 = 128 and 129, molar 1 = 119 and 125, molar 2 = 125 and 127.

Tscherski* calls the measurements belonging to the Tarpan "high," which in
the sense of Frank's method would assign this animal to the Oriental horse group.
He mentions, however, that in an Arabian horse these measurements are 115.7,
116.6, 117.6, 121.2, and 118.3; and in a horse from Dongola 116.6, 122.7, 122.5,
125, and 125, which correspond excellently with those of the Anau horse. Tscherski
says further that the maximum figures for this projection are found in the broad-
fronted races of fossils and recent Siberian horses. In the ass Tscherski found
strong variations, and in the half-ass a series of proportions which also were similar
