FOSSIL MAMMALIA. 85 



pared one of the teeth with those of a living rhinoceros which 

 he saw at Paris, immediately recognized the resemblance, and 

 thus the genus was determined. 



Pallas, in 1768, found in the fossil remains accumulated in 

 the cabinet of St. Petersburgh, four craniums and five horns 

 of the rhinoceros. The most perfect of the four craniums was 

 without the teeth. 



Fifteen years after he published a relation of the astonishing 

 discovery which he had made in Siberia oi slu entire rhino- 

 ceros^ with the skin found buried in the sand on the banks of 

 the Wiluji, in 64° north latitude. He adds the description of 

 a much more perfect cranium than any of the former, found 

 beyond the Lake Baikal. In many other parts of his travels 

 he speaks of fossil remains of the same species. 



There are not less of these bones found in Europe than in 

 Siberia. Besides those already mentioned, Zuckert has pub- 

 lished an account of some discovered at QuedHmbourg in 

 1728, in the same place where the pretended unicorn was dis- 

 covered in 1663, of which Leibnitz speaks in his Protogea. 

 This same unicorn, by the way, was spoken of before Leib- 

 nitz by Otto de Guerike, the celebrated inventor of the pneu- 

 matic machine. It was found in a calcareous and gypseous 

 hill at one league distance to the south-east of Quedlimbourg. 

 The bones had been in a great measure broken, until the time 

 in which the remnants were collected and deposited in the 

 abbatial palace. A sketch was then made of the animal, such 

 as it was pretended to have been found entire in the quarry ; 

 but a glance is sufficient to show that this sketch was done by 

 very ignorant hands, and taken after parts most incongruously 

 joined together. The bones of the horse seemed to have 

 formed a principal portion of the composition. The bones 

 described by Zuckert, being a considerable portion of the 

 muzzle, a portion of the humerus, a lower tooth, and an urt- 

 guical phalanx, belong, doubtless, to the rhinoceros with bony 

 partition of the nostrils.
