 The Earths. Neither have I had the good Fortune to meet with a Num- 

 ber or Variety of the Foffils of other Clafles. Thofe that are 

 not primitively fuch, but owe their Origine to the Deluge, (fuch 

 as are Foffil Shells, Sea Urchins, Corals &c.) will be enume- 

 rated in a particular Catalogue. Of the proper Foffils there-

 In pounding the Gypfum, we often meet with a Number of
