254 Miscellaneous Localities of Minerals. 
12. Galena, at White Creek, N. ¥. It was discovered 
about four months ago. It yields upwards of seventy five 
per cent pure jead. ? rations 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 specimens of the ore. 
13. Smoky quartz at Killingly. 
14, Ferruginous sand, in great abundance, at Block Is- 
d 
and. 
15. Green Talc, at Smithfield, 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 been taken from this locality, which weigh- 
ed 2 hundred and fifty pounds. It is of a brilliant colour, 
being of aijdeep 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.” 
A. Miscellaneous Localities, by Dr. Exen. Emmons, Ches- 
iter, 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, oF 
an aggregate of feldspar and hornblende, not stratified. 
Ph e of Lime.-In an aggregate of gray epidote, 
zoisite, ho nde and quartz. Dissolves slowly in nitric 
acid. Colour whitish yellow. Fragments transparent. 
m a rectal four sided pri } . 
Black oxide of Man web, P. Plainfield, sent me what 
he calls iron ore. Ihave lately ascertained that it is man- 
eas- 
associated with the above mineral, occurs in single oblique four 
sided prisms, with rhomboidal terminations and grouped,
