Miscellaneous Localities of Minerals. 49 



the hands of a lapidary. So far as I have examined them, 

 they appear to consist of granite, gneiss, sienite, sandstone, 

 porphyry, flinty slate, quartz, flint, chalcedony, jasper, 

 agate and onyx. They of course exhibit a variety of col- 

 ours; white, red, black, green, blue and yellow are the most 

 common. They also present a variety of forms, such as 

 globular, spheroidal, oval, lenticular, cylindrical, conical, 

 .&c. The surface of many of them is richly variegated. 

 Some are striped, some are spotted, some are banded, and 

 some of them are covered with various irregular and imita- 

 tive figures. Most of them are opake ; some are translucent ; 

 and some of them are semi-transparent.

[^Remark. — Specimens of the following minerals have 

 been forwarded by Dr. Robinson, and we publish his list 

 entire, although some of the localities have been already 

 noticed in this Journal.- — Editor.] 



1. Amethystine Quartz,'^ Bristol. 



2. Augite, in talcose slate, Middletown, R. I. 



3. Basanite, Newport. 4- Serpentine, do. 



5. Shale, with vegetable impressions, Popasquash Island. 



6. Staurotide^ in mica slate. Cannonicut Island. James- 

 tow^n. 



7. Garnets, in talcose slate. 



8. Rhomb Spar, Green Talc, Fibrous Talc, and Quartz, 

 Smithfield.

* Other very fine specimens have been received, from the Franklin Society 

 of Providence ; they are from the same locality and are remarkable both 

 for their size and the depth and richness of their colour. Gne piece cut, 

 polished, and set in gold by Mr. George Baker, Jeweller, (No. 61, opposite 

 the Baptist meeting house,) Providence, bears an advantageous comparison 

 with the finest foreign specimens. Mr. Baker is, evidently, worthy of 

 encouragement and patronage, from the friends of this elegant department 

 of the arts. — Editor.
