230 Miscellaneous Localities of Minerals. 
locality, if properly managed. Many specimens have been 
sent here, to be cut and polished by Davis & Babbitt, lap- 
‘idaries, and to be set by Col. Baker, for breast-pins, ear- 
rings, and other articles of ornament. Carbonate of won 
in considerable quantities, is found at the locality of yenite, 
tremolite, epidote, &c. in Cumberland. We occasionally 
meet with specimens of semi-transparent quartz, containing 
within them small crystals of yenite. 
Amethyst is found on the banks of the Blackstone River, 
in Cumberland. We have not had an opportunity as yet 
of examining this locality, ‘sufficiently to decide whether it 
will probably prove to be as importantas that at Bristol. 
Very large crystals of quartz of the common form, with 
perfectterminations, are ploughed up upon Cu mberland Hill. 
Idrocase is found in the walls back of Brown University. 
REMARK BY THE EDITOR. 
Prof. Dewey, at p. 50 of our Jast number, has question- 
ed the propriety of applying the name Vermiculite to a par- 
ticular variety of tale described by Mr.'Webb, p. 55, Vol. 
VII. We have received a letter from Mr. Webb, dated 
June 26, in vindication of the name above mentioned :— 
_ but we conceive it ‘unnecessary to publish his remarks at 
large, because his reasons are sufficiently explained in the 
original communication already alluded to. 
In confirmation of Mr. Webb’s observations as to the cu- 
rious effects of heat, we would add, that specimens brought 
to us, two or three years ago, from the same locality, by 
Dr. D.S. C. H. Smith, of Sutton, exhibited under the 
blowpipe the same appearances which are so accurately 
described by Mr. Webb.*
