Stauroiide? 
A mineral resembling the so called Staurotide (?) found at the Canton Mine, 
Georgia, described by Prof. Shepard, (3d Supplement Dana's Mineralogy, p. 16,) 
I have found some time since, at a copper mine near Webster, Jackson Co., N. C. 
associated with automolite crystals as at the former locality. The prelimi- 
nary analyses made of the mineral from the Canton Mine by Dr. Genth and my- 
self, (the results of which agree,) renders the conclusion as to its being Stau- 
rotide very doubtful. 
Cuproplumhite ? 
Among the ores brought home by Dr. Le Conte from his recent explorations 
in Honduras, was a specimen which particularly attracted my attention, from 
the mine of Antonio Cruz, near Comayagua ; apparently it is galena, being 
massive and granular, with a cubical cleavage, on the faces of which there is a 
bronze tarnish, which gives the effect of a play of colors not unlike that on 
Bastite (Schiller Spar), the color being more coppery. On the edges it is de- 
composed, forming massive carbonate of lead, whilst the copper (in little geodes), 
as crystallized malachite, is disseminated through the mass. 
B. B. lead, copper and a trace of antimony, streak black ; sectile and brit- 
tle ; fusible in an open glass tube over a spirit lamp. 
Notwithstanding the similarity between its reactions and that of the cupro- 
plumbite analysed by Platteser, this may be only a cupriferous galena as occurs 
in Tuscany, but the peculiar bronze hue of the cubical faces indijiccd mp-tg 
mention it among these notes. As soon as time permits I will analyse it quan- 
titatively. 
HydropJtiie 9 
The mineral described by Dr. Genth, from Texas, Lancaster Co., Pa., (Keller 
and Tied. Nordamer. Monatsb. iii., 487) as Nickel-Gymnite, but which Prof. 
Dana (System Mineralogy, p. 285) considers a variety of Hydrophite, I have 
found near Webster, Jackson Co., N. C. in a band of serpentine, associated with 
chrome iron ; (this band of serpentine is about two or three hundred yards in 
width, bearing N. E. and dips S.) It occurs as an amorphous reniform incrus- 
tation on a brownish green, granular serpentine, in which are crystals of chrome 
iron. Its hardness is about 3; lustro resirous ; its color varies from an apple 
green to a yellowish green, streak greenish white. In a matrass, yields water. 
B. B. nickel and silica.

On leave granted, a vote of thanks was presented to Dr. C. M. Cresson, 
for the donation of supposed fossil ripple-marks presented this evening.
