The remains thus far discovered are of such interest as to 

 encourage Mr. Paret to continue furtlier exploration Most of 

 these collected to the i)resent time were exhibited by Prof. Leidy, 

 and consist of the following : 



Numerous fragments and splinters of limb bones of smaller and 

 large animals, man}- or most of which exhibit the marks of being 

 gnawed, whether by rodents or small carnivores is somewhat im- 

 certain. A few also show the marks of canine teeth, of medium 

 sized carnivores. Some of the splinters pertain to such large and 

 strong bones as to render it questionable whether they were pro- 

 duced by even our largest carnivores, and probably are the rem- 

 nants of human feasts, in which the bones were crushed to obtain 

 the marrow. Numerous bones and fragments of others of the 

 smaller and smallest animals. These include especially limb 

 bones, and lower Jaws, and less frequently skulls, fragments of 

 others and vertebrae. Many of these are also gnawed, while many 

 are not. 



The fragments of larger bones may be supposed to have been 

 conveyed into the cave by small carnivores. A few pieces of bone 

 are somewhat charred ; and a small fragment of a lower jaw, con- 

 taining a molar tooth, of the Bison, also apparently exhibits 

 the marks of fire. This probably is a remnant from a human 

 feast, which may have been carried into the cave' by some small 

 gleaner. 



All the bones and fragments together amount to about half a 

 bushel. Most of them pertain to animals of a kind still living, 

 though some of these no longer belong to the fauna of our state, 

 and a few of the remains are those of extinct animals. How far 

 the remains of different species are cotemporary is uncertain, 

 though it is most probable that they were introduced through a 

 long succession of years from the time following the glacial period. 



The remains of extinct animals consist of an incisor tooth and 

 half a dozen molars of the great rodent Gasforoides ohioensis^ 

 and portions of the upper and lower jaw, with teeth, of a young 

 Peccary, the Dieotijles nasutus, previously known only from a 

 single fragment of an upper jaw, discovered in Indiana, (Extinct 

 Mammalia of North America, 385, pi. xxviii, figs. 1, 2. Jour. 

 Acad. Nat. Sc, vii, 1869). 



The remains of animals no longer living in Pennsylvania are as 

 follows : 



Bones and teeth of the Caribou or Woodland Reindeer, 

 Rangifer caribou. 



A fragment of the lower jaw containing the last molar tooth, of 

 the Bison, B. americanus. 



Man}- lower jaw halves, and other bones and teeth of the Wood- 

 "rat, Neotoma fioridana. Most of these ai'c of comparatively large 

 size, and of the character of similar remains referred by Prof. 

 Baird to a supposed extinct species, with the name of Neotoma
