Art. XXXIIL— iVbiice of the discovery of a Cave in Eastern Penn- 

 sylvania^ containing remains of Post-PUocene Fossils, includiwj 

 those of Mastodon, Ta-pir, Megahnyx, Myhdon, etc.; by Charles 

 M. Wheatley. 



The remains herein described were recently discovered in 

 what was at one time a cave, in the limestone quarries at Port 

 Kennedy, Upper Merion township, Montgomery county, Pa., 

 owned by John Kennedy, Esq., to whom I am indebted for the 

 possession of the remains, and who has afforded me eveiy facil- 

 ity for exploration and investigation. 



The cave is in the Auroral Limestone of Rogers, regarded as 

 the equivalent of the Black River and Chazy Limestones and 

 Calciferous Sand Rock of New York, at its junction with the 

 Mesozoic Red Sandstone and near a belt of the Primal senes ot 

 Rogers, (fig. 1.) Caves of more or less extent have often been 

 met with in these quarries ; but most of them have been 

 entirely worked away in getting out the stone for lime, and, as 

 tar as ascertained, none of them communicated with the surface, 

 or containprl nnrr organic remains, ,,

 rhole of the walls of which cave had been
