'HE FOSSIL SLOTH AT BIO BONE CAVE, TENN. [Jan. 15, 



KlG. 2 (x Jo). — :Specinieiis of the cave rubbish, 

 fragments of cave clay and coproHtes ; 3, of porcu- 

 pine, Erethizon dorsatus ; 4, of cave rat, Neotoma 

 magister, and the cast-away ends of torches resting 

 on the surface of the cave floor (Layer i), above 

 the spot where the sloth bones were unearthed; i, 

 Arundinaria tecta; 2, charred splinters of pitch 

 pine, Finns mitis, and seven charred twigs of hazel, 

 Corylus americana.

 because the evidence 

 indicates that there was 

 only one sloth at this 

 point, with no reason 

 shown why there should 

 have been more than 

 one, and because it ap- 

 peared that no other 

 spot adapted for the 

 discovery of fossil 

 bones had existed at 

 the entrance of the 

 cave, for these reasons, 

 I believe that the Nash- 

 ville bones and my set 

 go together as parts of 

 one animal ; and fur- 

 iher, as first suggested 

 by Prof. Safford and 

 now shown by my ex- 

 amination, let me add 

 tJTat still another and a 

 third set of sloth bones, 

 belonging to the Acad- 

 emy of Natural Sciences 

 of Philadelphia, here- 

 with shown (see Fig. 3 

 for one of them), found 

 by a farmer in the cave 

 and described by Dr. 

 Harlan in 1835, also 

 showing cartilage
