Extract of a letter from Mr. Stephen C. Wiliams to the Editor, dated 
: ' Mipp.erown, Oct. 8th, 1825. 
Dear a , 
I have taken the liberty of sending you with this letter 
specimens of some minerals, no localities of which have beer

These particulars, corresponding so neatly with thie deserip- 
tion of the Chesterfield locality, seem to afford strong ground 
of Sends that the minerals discovered here are of the 
same spe 
Remarks by the Editor. 
We have the satisfaction of agreeing with Mr. Williams in 
all the — t has expressed, and of adding, that the spe- 
chatacterized as to justify further research, 
and there es oe lithe dowbt that these interesting minerals 
will soon be found tin place, unless indeed they were years 
ago thrown out from the pits and?galleries of the old aban- 
doned lead mines which are now filled with water. Mineral- 
-ogists will learn with interest, that the place mentioned by
