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 prisons) than in the Urms, 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 slendcrness in the swift-footed deer- 

 race ; and that the same bones also in the horse rire much longer 

 than in the ox, in proportion to the magnitude of the re$t of
