CHAPTER XIX. 
THE HORSE OF ANAU IN ITS RELATION TO HISTORY AND THE RACES OF 
DOMESTIC HORSES. 

(Plates 87-91.) 
Having, in chapter xvur, endeavored to prove that the equid of the North 
Kurgan of Anau is a horse and not an ass, and to show its relation to other Asiatic 
Equide, and further to picture the changes it underwent during the life of the 
civilizations of that kurgan, I shall now consider the relation in which the Anau 
horse (Equus caballus pumpellii mihi) stands to the subfossil horse and to some 
historical domestic breeds, as well as to the Equus przewalskii Polyakoff. 
As is commonly known, the domestic horses are generally classed in two 
groups: the Oriental and the Occidental. Frank* calls the first of these groups 
also Equus parvus, and the second Equus robustus, and discusses at some length 
the points of difference between the two types. In this connection I will state 
briefly some points which have not been sufficiently touched upon in the previous 
chapter. 
In the Oriental horse, especially in the Arabian, the brain-skull is, relatively, 
very strongly developed; the face less so. These horses are called broad-headed, 
because the width of the forehead is large in comparison with the length of the 
skull. We have already spoken of the teeth; regarding these we may here refer 
especially to the anterior and posterior crescentic islands (Owen’s terminology), 
in which the enamel-margin is not so wavy; the internal lobe is placed just in the 
middle of the grinding surface, and its division into two is not very clearly marked. 
The hollow bones are remarkable for their graceful shape and solid, hard texture; 
the metacarpal bones are relatively narrow. In many points, therefore, this 
group of horses resembles the ass. 
On the other hand, these same points distinguish the Occidental from the 
Oriental horse. In the Occidental horse the facial part of the skull predominates 
at the expense of the brain-skull, the skull appears long and narrow, the forehead 
is narrower, the rim of the eye-socket is but slightly prominent. The enamel- 
margin of the crescentic islands is very wavy, and the internal lobule is divided 
into two very distinct horns and flattened. The bones of the extremities are 
heavy and massive, while their texture is less dense and hard than in the Oriental 
horse. ‘The tarsal bones are generally broader than in the latter group. Again, 
Sanson,t applying Broca’s anthropological method, has proposed another classi- 
fication of horses based on dolichocephaly and brachycephaly, dividing them into 
four dolichocephalic and four brachycephalic races; but it has not been possible 
to maintain this division in practice, as it is too schematic. We can not consider 
here other attempts at classification.
