If we now compare this measurement with that of the Urus, 
(Bos primigenius) which will be found in p. 260, we shall there 
see, that while all the other bones in the extremities are longer 
in the Aurochs (Bison priscus) than im the Urus, this relation is 
reversed with regard to the metacarpus and metatarsus ; for these 
are certainly longer in the Urus. They are not only longer— 
they are also thinner, although the whole skeleton in the re- 
maining parts is stouter. When we consider the peculiar cha- 
racter of these bones, namely that they are remarkable for their 
uncommon length and slenderness in the swift-footed deer- 
race ; and that the same bones also in the horse are much longer 
than in the ox, IN proportion to the magnitude of the rest E of
