Among a large collection of fossils presented to the 

 Lyc. of Nat. Hist, of N. York, by the late Dr. Mitchell,

Only slight indications of the existence of a fossil 

 Morse or Walrus have been hitherto observed in any 

 country ; a few molar teeth, and some fragments of bone 

 found in France, have been referred to this species. In 

 the work above alluded to, Mr. Cooper has given a lucid 

 account of a mutilated fossil skull in the cabinet of the
