SIR, 
ALthough I fear the Dodlrine of petrification will receive 
but little light from this Account, yet fince you may de - 
duce more from it, than I forefee, I have at your Requeft 
fent it to you. 
My Brother at the opening of a piece of Ground, at his 
houfe in Hunt on ^ (five miles from this place /and about a 
quarter of a mile from the River Medway. i . After the 
coping was taken off (which was a Clay about three foot 
deep, j He came to a very good blew Marlejwhich continued 
fuch three feet and i deep more, and then there appeared a 
hard floor or pavement compofed of Shells, or ihell-like 
ftones <, crowded clofely together 3 the interftices whereof 
were filled up with the lame Marie. This layer (which 
runs as the veins of Hints do in chalky Earth ) was about an 
inch deep, and feveral yards over, and we could walk on it, 
as on a Beach. Under this layer we came to Marie again ; 
but the depth I do not well remember, I think it was a foot : 
this ground hath a pond on one fide of it, which probably 
was heretofore a marl pit, and it is almoft furrounded with 
Springs, which firft encouraged my Brother to the opening it, 
his defign being to enlarge the Pond I cannot upon enqui- 
ry find that in the memory of any man thereabouts, any 
floods from the Riycr have reached fo far as this place. 
Thefe Stones ( for I take them to be lafides fui Generis ) 
are of that fort which is called Conch'ues ; and relemble 
Sea-fifh of the teftaceous kind. Mofl: of them are turbina- 
ted, or wreathed, the reft are of the bivalvular fort, but I 
have not found any of them with valves clofed together, 
but fingle. 
The bignefs of the turbinated, is from a Vetch, to a Fla- 
fell-Nut, they are all filled with a Ttrra lapdcfa, like the 
Marl,^ and are of that colour, till yon have wafhed, and rub- 
bed them, and then they appear of the colour of Bezoar, 
and of the famepoliture. After they have been boiled in 
water , they are whitifh, and leave a chalkinefs upon your 
fingers, which when it is rubbed off, gives you a view of 
very fine black/n^, thick fet on the outfide. Thefe wreath'd
