Miscellaneous Localities of Minerals. 225 
ous masses of malleable iron, which have been found in 
different parts of the world, on, or just beneath, the sur- 
face of the earth, affords almost decisive proof of their 
common origin. The experiments mentioned in the no- 
tice quoted above from Dr. Bruce would indicate that the 
large mass in New-York forms an exception to this simi- 
larity of composition, but experiments instituted more re- 
cently by Prof. Silliman, and stated by Col. Gibbs in the 
notice already alluded to, have detected nickel in this 
mass. ‘There is much reason to believe therefore that it 
had a common origin with numerous other masses, found 
in various places, and containing malleable iron and nick- 
el—some of which are known to have proceeded from me- 
teors.  ~ C. H.

1. By Srevsen Tavtor and Tuomas H. Weep. 
1. Serpentine, at Newport. It is situated on the Neck, 
about a mile south-west of the town, occurring in rocks of 
the secondary formation. The prevailing colours are yel- 
low, yellowish green, and greenish black. When polished, 
it exhibits a variegated and beautiful appearance. A tract 
of four or five acres is covered with these rocks, and there 
is reason to believe that, should they ever be quarried, they 
will yield an ample reward to those who may engage in the 
enterprize. 
2. Asbestos is associated in small quantities with the 
above. 
3. Jasper, at Pawtuxet. It is found abundantly in roll- 
ed masses, on the shore E. and 8. E. of the village. 
4, Vegetable impressions on argillaceous shale, at do. 
They are found in water-worn fragments along the shore, 
for the distance of halfa mile. Some of the shale appears 
in situ about ten feet from the top of the bank. The im- 
pressions differ from those that have been before observed 
in this State; although the shale is probably a continuation 
of that which is associated with the anthracite on Rhode- 
Island. We find among them the Pteris aquilina, the 
Comptonia asplenifolia, and the Bellis perennis.
