The existence of this property is doubtless dependent upon 
the same general causes in marble as in other dense bodies. 
From the extensive view of marble given in Rees’ ph 2 
pedia, flexible marble appears to be a rare mineral. One o 
the specimens I have lately obtained is to be sent by the roy 
trian Consul, to the Imperial Cabinet of Vienna. As more 
specimens may doubtless be obtained at a reasonable expense, 
I would gladly aid those mineralogists who desire to procure 
specimens for their cabinets.

ite the minerals of Franklin, first described by Mr. 
Nuttall, drew so much attention, and omwes so interesting to 
naturalists, I vse endeavoured to collect as many specimens 
dvspospli; both for my own amusement and that of others. 
With this view I oe attended to the panier formation, in 
which they are found, and have endeavoured to Nee ees it in 
ail its extent. It is almost unnecessary to repeat that every 
thing extraordinary in the valleys of Sparta, Franklin, and 
Warwick, belongs to the formation of crystalline. limestone, 
— perhaps, has no parallel in any other region of 
orld. Even Arendal and Wtoe are inferior in mineral riches

While recently exploring this formation, I made a discovery 
inthe township of Warwick, Orange county, N. ¥. of mine- 
rals, the most shen for magnitude and beauty, which 
have ever yet come to notice. What will be thought of Spin- 
elle pleonaste, the side of one of whose bases measures three 
to four inches, or twelve to sixteen inches in circumference ? 
These crystals are black and brilliant, sometimes aggregated, 
at other times solitary ; at this locality seldom or ever less
