‘Tats valuable Earth is rather peculiar to Great Britain ; it 
is, however, said to be found in Saxony, Alsace, and 
Sweden. Hampshire and Bedfordshire are the only two 
places mentioned in England by most authors. Dr. Thom- 
son says, * It occurs in greatest perfection in the South of 
England.” J, however, cannot find out that any has been 
discovered in Hampshire 5 and indeed the analysis usually 
quoted from Bergman does not appear to me to indicate 
Fuller’s Earth*. His Grace the Duke of Bedford was so 
good as to supply me with an excellent specimen from 
Aspley ; and I have seen the pits in Surry and Kent. A 
sori is also found in Nottinghamshire. I exhibit a small 
* Tt isremarkable, hat of many acquaintances of whom I have inquired, 
there is not one who can find out any place in Hampshire where it is found, 
and I suspect something wrong in all that quote Bergman’s Analysis.
