rous mammalia, and was as massive in its proportions ; for, 

 living exclusively on vegetables, it must have had the abdo-

Its limbs must have been of proportionate size and 

 strength to sustain and move so enormous a carcass ; the 

 hinder extremities, in all probability, resembled the unwieldy 

 contour of those of the Hippopotamus or Rhinoceros, and 

 were supported by strong, short feet, protected by broad 

 ungual phalanges : the fore feet appear to have been less 

 bulky, and adapted for seizing and pulling down the foliage 

 and branches of trees j the jaws and teeth demonstrate its 

 power of mastication, and the character of its food ; while the 

 remains of coniferous trees, arborescent ferns, and cycadeous 

 plants, which are found imbedded with its remains, attest the 

 nature of the flora adapted for its sustenance.
