244 Bn Account of some New and Extraordinary Minerals, 
ef an extraordinary form, having the obtuse angle sometimes 
replaced by a broad face. Near Franklin I have found 
most beautiful mass of greenish white tremolite of this form 
also, the lustre of these crystals is like that of silk. 
Crystals of augite abound here, of gigantic magnitudes; 
and sometimes when smaller, of considerable perfection of 
form; they are generally grayish green. Brucite also oc: 
eurs here of a beautiful orange and ofa palisli yellow colour ; 
the paler coloured variety is occasionally crystallized in ap- 
parently modifications of the rhombic prism, but hitherto un- 
measured. The orange coloured are imbedded in a bluish 
limestone. The blue limestone also occurs in this vicinity 
in globular concretions loosely aggregated, very similar to the 
blue limestone of Vesuvius and the Bannat. 
na very singular bed, subordinate to, atid indeed im the 
erystalline limestone oecurtiig inthe form of a breccia of the 
old red sandstone. red graphic granite, and white feldspar, I 
have found partly diaphanous, softish, green octahedral crystals 
of considerable magnitude for which 1 know of no ascertained 
character.’ They appear almost similar in substance to stea- 
tite, being easily cut by a knife. They are not however found; 
as the spinelle of this locality; in carbonate of lime. Con- 
idering therefore this mineral as new, I pro to call it 
w; pose 
_in allusion to its affinity to the pseudomorphous _ 
trystals of stedtite. 
In addition to the numerous niinerals which have been 
found at Franklin and Sterling, I would mention the follow- 
ing as occurring at Franklin. 
Masses of actynoliie, of a bright silky lustre, containing 
short and much modified crystals, the acute lateral edge being 
in some replaced by three faces and the obtuse angle oblite- 
rated. ‘T’his mineral is sometimes associated with phosphate 
of limé and scapolite. 
Red spinelle; in small scattered crystals, associated with 
brucite, beryl, and phosphate of lime, found near tbe mill-dam. 
Parallel, or nearly so to the same ledge, it was also found by 
Mr. Nuttallin a small specimén which was not ascertained at 
the time of his publication. 
~ Amorphous pale yellow é/ende in a brecciated tock dccom- 
vanied by carbonate of lime. 
Carbonate of manganese, a somewhat friable reddish gray 
atone; forming a thin bed in the franklinite at the summit of
