safety unless supported in the middle as well as at the ends. 

 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' Cyclo- 

 paedia, flexible marble appears to be a rare mineral. One of 

 the specimens I have lately obtained is to be sent by the Aus- 

 trian Consul, to the Imperial Cabinet of Vienna. As more 

 specimens may doubtless be obtained at a reasonable expense, 

 1 would gladly aid those mineralogists who desire to procure 

 specimens for their cabinets.

Art. V. — An account of some new and extraordinary mint' 

 rah discovered in Warwick, Orange county, JV. Y. ; by 

 Samuel Fowleh, M. D. 



Since the minerals of Franklin, first described by Mr. 

 Nuttall, drew so much attention, and appeared so interesting to 

 naturalists, I have endeavoured to collect as many specimens 

 as possible, both for my own amusement and that of others. 

 With this view I have attended to the peculiar formation, in 

 which they are found, and have endeavoured to explore it in 

 all 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, 

 which, perhaps, has no parallel in any other region of the 

 world. Even Arendal and Wtoe are inferior in mineral riches 

 to this crystalline calcareous valley. 



While recently exploring this formation, I made a discovery 

 in the township of Warwick, Orange county, N. Y. of mine- 

 rals, the most exlraordinary for magnitude and beauty, which 

 have ever yet come to notice. What will be thought oiSpin- 

 elle pleonasie, the side of one of whose bases measures three 

 to four inches, or twelve to sixteen inches in circumference ? 

 These crystals are bjack and brilliant, sometimes aggregated, 

 at other times solitary ; at this locality seldom or ever less 

 than the size of a bullet. Some are partly alluvial, their mat- 

 rix decomposing, but when unaltered they are found asso- 

 ciated with what has never yet been described, namely crystals 

 of serpentine, slightly rhomboidal prisms of a magnitude par-
