206 Middletown Minerals. 
8. New Locality of Rubellite, Beryl, Tourmaline, &e. 
Extract of a letter from Mr. Stephen C. Wiliams to the Editor, dated 
Mipp.etown, Oct. 8th, 1825. 
Dear Sir, 
I have taken the liberty of sending you with this letter 
specimens of some minerals, no localities of which have been 
before noticed in this place. 
The light green crystals were found imbedded in the gra- 
nite rocks near the lead mines, two miles below the city. 
Their form, most of them being six sided prisms, their co- 
lour, and their hardness, which is greater than that of quartz, 
induce me to think that they are beryls. Some have been 
obtained five or six inches in diameter, and eight or nine in 
Jength. 
The pink coloured specimens were discovered ina detached 
mass of the granite inthe same vicinity, and from the informa- 
tion which I have been able to gather by referring to Cleave- 
land, | flatter myself you will pronounce them rubellite. In 
the larger of the two, you will observe a green substance 
which [ concluded must be tourmaline ; in the same piece 
there is also a small crystal in which the tourmaline, if it be 
so, is enclosed in the rubellite. A small specimen of rose co- 
Joured mica accompanying it was found at the same place. 
‘These particulars, corresponding so nearly with the deserip- 
tion of the Chesterfield locality, seem to afford strong ground 
of probability that the minerals discovered here are of the 
same species. 
Remarks by the Editor. 
We have the satisfaction of agreeing with Mr. Williams in 
all the opinions he has expressed, and of adding, that the spe- 
mens are so well characterized as to justify further research, 
and there can be little doubt’that these interesting minerals 
will soon be found in place, unless indeed they were years 
ago thrown out from the pits andfgalleries of the old aban- 
doned lead mines which are now filled with water. Mineral- 
-ogists will learn with interest, that the place mentioned by
