254 Miscellaneous Localities of Minerals. 



12. Galena, at White Creek, N. Y. It was discovered 

 about four months ago. It yields upwards of seventy five 

 per cent pure lead. Preparations for working it were com- 

 menced some time since. For this information respecting 

 this locality, I am indebted to one of the proprietors, from 

 whom I received specimensof the ore. 



13. Smoky quartz at Killingly. 



14. Ferruginous sand, in great abundance, at Block Is- 

 land. 



15. Green Talc, at Smithfinld, R. I. It is in the centre 

 of a public road, about a mile west of Cumberland Hill. It 

 was discovered nearly a year and a half ago, by the Hon. 

 Samuel Eddy, and Dr. Charles B. Halsey of this town. 

 Specimens have beei; taken from this locality, which weigh- 

 ed a hundred and fifty pounds. It is of a briiiiant colour, 

 being of a deep green, particularly when viewed in the di- 

 rection of the laminae. From experiments which have been 

 made upon this mineral, it is found to lessen friction better 

 than graphite." 



4. Miscellaneous jLocaZi^ies, by Dr. Eben. Emmons, Ches- 

 ter, Mass. 



Silico Calcareous Oxide of Titanium. — Oblique four si- 

 ded prisms, (rather imperfect,) of a light brown colour, as- 

 sociated with Augite and Actynolite; likewise in Sienite, or 

 an aggregate of feldspar and hornblende, not stratified, 

 Chester. 



Phosphate of Lime. — In an aggregate of gray epidote, 

 zoisite, hornblende and quartz. Dissolves slowly in nitric 

 acid. Colour whitish yellow. Fragments transparent. 

 Form a rectangular four sided prism. Chester. 



Black oxide of AJanganese.-Dv. P. Plainfield,sent me what 

 he calls iron ore. I have lately ascertained that it is man- 

 ganese, yields a large proportion ofoxigen,and comes off eas- 

 ily at a low red heat, and as abundant as the Bennington M- 

 Dr. P. has not informed me whether it is abundant, but at any 

 rate I believe it is of a good quality. Cumraington or Plain- 

 field. Chabasie, in cuboidal crystals, one quarter of an inch 

 in diameter, of a straw yellow and white colour. Stilbite, 

 associated with the above mineral, occur* in single oblique four 

 sided prisms, with rhomboidal terminations and grouped,
