nerally upon the Surface, perilh’d, and are at this day rarely 
met with. 
Caufing one fo dig into the Moorifli Ground above- 
mentioned, we found a (mall number of Snail Shells of 
various kinds buryed there. At about a foot in depth 
they lay very thick $ and finking ftill downwards the 
number rather encreafed till we came to the depth of 
about three foot. ’Twas troublefome to fink deeper on 
purpofe 5 but we made Tryals for a confiderable extent 
of Ground, viz. about 25© foot in length, and 130 in 
breadth. Befides, the fame Shells were caft up in feveral 
places, at difiance, by Moles. What we principally ob° 
ferved in this fearch was 1. A moift Moorifh black Earth, . 
in fome places a foot and a half, in others fome what 
above two toot in thicknefs. The lower half of it is 
blacker and denfer than the upper half, of a Bituminous 
Nature, and has all the Characters of Peat-Earth. Be- 
fides Shells we found Stalks and Leaves of Grafs, and allb 
of many Kinds of other Vegetables repofited as ufual in 
like Bituminous Moors, in other parts of this Ifland, 
2. White Earth 5 fo at firft We call’d if : But upon 
clofer InfpeCtion it appear’d to be little more than Hay 
half wafted. So deep as we funk into it, we found it 
every where copioufiy interfpers'd with Shells. 
The finding thefe Shells Under Ground made it very 
reafonable to enquire whether there were any of the like 
at this time living upon the furface. I diligently fearchU 
this place, but cou’d not meet with any Live ones of any 
Kind whatever there. 
The Foffil Shells were fome the Eximi<e of Land- Snails, 
the reft of River or Frefh Water- Snails : Of the fonner 
there were the three following kinds. 1. A final \ Bttcci-
