 it was imagined they were petrified 

 Tongues ; but they are in truth the 

 Teeth of Sharks and other Fifli, fome- 

 times adhering ftrongly, and partly bu- 

 ried in a ftony Subflance, at others loofe 

 our more modern Naturalifts have very 

 properly called them Ichtyodontes, 



Under this Title are alfo depofited 

 fome Specimens of the Bufonites^ or, as 

 Dr. Hill more properly calls them, Lyco- 

 dontes^ as they are found to be the Denies
