extremely fatisfied with the account Mr De La Prhr 
gives us of his Obfervations on the Shells in the Quar^ 
ries near Broughton^ efpecially with the agreeable not^ 
ons he has conceived of the Deluge of Noah. 
To the many inftances the Earth gives us ^f the 
great and violent mutations (he has fuffer'd, be pleafed 
to take a remarkable one of thofe I have obferved in Kenu 
About half a mile from Recnlver^ towards Herm, 
there appears in the Cliff a Strata of Shells in a greenifh 
Sand 5 they feem to be firm, and fome of them are en-

they crumble to Powder between your fingers ^ but that 
which is moft remarkable is, that in the lower part of 
the Strata, where the Shells are more thickly difperfed, 
there lies fcatter d up and down portions of Trunks, 
Roots and Branches of Trees 3 the Wood is become as 
black as Coal, and fo rotten that large pieces of it are 
eafily broken with ones fingers. I know not what 
depth thefe may lye, the Strata's furface not appearing 
above 2 foot from the Beach, but I judge it from the 
fuperficies or top of the ClifF about 12 foot. I faw the 
ftump of one Tree ftanding upright broken off about a 
foot from the ground. I fliould have given a more 
particular account, but cannot at prefect find the not@ 
I took upon the place. I (hall only add, that the Shells 
were of the White Conchites. , 
Give me leave to conclude the remaining part of thi$ 
Paper on another fubjeft. I have lately thought of & 
new contrived Inftrument for Drawing a Meridian line^ 
which, for any thing I know to the contrary, is my 
own 5 'tis eafie in its ufe, and fufficiently exaft : I be-

Take the Gnomon of an Horizontal Dial for the Lati- 
tude of the place, and to xh^ Hypothennfa fix tw^o Sights^ 
whofe centers may be parallel to the fame ^ let the Eye-
