 they really belonged to a terrestrial animal, 

 whose species approached that of the hippopo- 

 tamus more than any other." 



In this state of uncertainty continued the

 the great American Incognituin^ as it was fre- 

 quently called, until a recent discovery in the 

 neighbourhood of our cities, afforded us al- 

 most a complete idea of the whole skeleton ; 

 and the world is now in possession of two un- 

 disputed skeletons of this animal, found in 

 such situations as leave no room for conjec-» 

 ture ; each skeleton being dug up in a sepa- 

 rate place, without any intermixture of forci^^n 

 bones, and each bone exactly adapted to its cor- 

 responding points of articulation. One of these 

 skeletons is erected, as a permanent speci- 

 men, at my father's museum, in Philadelphia, 

 where it will remain a monument, not only of
