64 INTRODUCTION. 



Although different authors have bestowed specific 

 names upon the remains of these animals found in 

 different places, such as Hippotherium of Caup, 

 Equus fossilis, Equus Adamiticus, of Schlotheim, 

 Equus (Cahallus) primigenius, Equus (Mulus) primi- 

 genius, and Equus (Asinus) primigenius, we find, 

 from the confession of Baron Cuvier, that he never 

 discovered a character sufficiently fixed in the exist- 

 ing species, and therefore still less in the fossil, to 

 enable him to pronounce on one from a single bone. 

 All the remains of Equidse hitherto discovered, ap- 

 pear so perfectly similar in their conformations to 

 the domestic horse, (Equus Caballus,) that they can 

 scarcely, or at most only in part, be ascribed to other 

 species of the genus. From the commixture of their 

 debris, there cannot be a doubt that they have existed 

 together with several great pachydermata, and with 

 hyaenas, whose teeth have left evident marks, pro- 

 miscuously, upon a great number of them : but what 

 in this question is deserving of attention is, that 

 while all the other genera and species, found under 



pletely fossilized. Horse bones, accompanied by those of 

 elephant, rhinoceros, tiger and hyaena, rest by thousands in the 

 caves of Canstadt, in Wurtemberg; they have been found with 

 elephant bones at Sevran, in digging the canal of Ourcq ; 

 at Fouvent-le-prieure' ; at Argenteuil ; in Val d'Arno with 

 Mastodon ; and on the borders of the Rhine with colossal 

 Urus. Crawfurd does not notice any among the organic re- 

 mains observed by him in Ava ; but Captain Cantley found 

 Equine bones in the sandstone, and among fallen cliffs of the 

 Sewallick mountains, at the southern base of the Himalayas 

 between the Sutleje and the Ganges.
