surface, under mixed sand, and differs also from that int 
being found with much water, and not being in large 
pieces, or above half a pound, as well as. in requiring 
careful picking and washing ; when it is laid out to dry, 
and then shedded for carting to the Medway. It is rather 
softer to the touch than the kind from Surry, but generally 
dries darker, and has a more ochraceous crust. The three 
sorts of which I have spoken have all a very similar fracture, 
perfectly conchoidal, with a reverse inclining to the letter S. : 
Nottingham Fuller’s Earth, lower figure, varies like the 
others, but is generally more opaque and soft, rather than 
waxy, in appearance. What has been sent me evinces the 
admirable contrivance of Nature. The former varieties were 
infiltrated through sand and between stones, whereas this is 
preserved, as it were, in large nodules of red clayey Sand- 
stone, and is thus as effectually distinguished as the kernel 
of a nut.. I understand these are found in sandy rocks, and 
that women and children strip the Fuller’s Earth of its co- 
loured covering. 
This earth is met with in other places, but I believe not in 
sufficient quantities for market. 
These specimens of this substance, from what I can judge 
of them without analysis, are of the best sort, and should 
seem to contain much Magnesia. Its waxy, soft, or 
unctuous appearance would indicate it to be a Steatite Clay, 
and its greenish hue certainly bespeaks the presence of Fale 
or Chlorite, which is so well incorporated with it as to seemr 
to help its granular texture. In fine, it appears a more de- 
composed state of Steatite, like many of the neighbouring
