Dr. Gen til made some remarks upon a new meteorite from 

 North Carolina, which he desired to be considered prelimi- 

 nary to a description and fall analj^sis of the same. Prof. 

 Kerr had forwarded photographs of the mass. 



Dr. Genth showed also, specimens of metallic lead and me- 

 tallic iron from Gold tailings on Camp Creek, Montana Terri- 

 tory. The place, circumstances, absence of all meteoric indi- 

 ' cations, and presence of gold in the lead, support the view 

 that we have here a genuine discovery of lead and iron in a 

 state of nature. 



Dr. Geiitli showed photographs of a new meteoric iron, weighing about 

 twenty pounds, which was found on a small mount in Rockingham Co., 

 N. C. ; he made some preliminary remarks on a fragment of the same, 

 which he received from Prof. W. C. Kerr, State Geologist of N. C. The 

 iroa is coated with a crast of hydrated sesquioxide of iron. A polished 

 portion of it, after etching with dilute nitric acid, developed the Widmann- 

 staedtean figures, and showed a very remarkable structure of the iron. It 

 is composed of three different kinds of iron ; one portion of it is quite 

 homogeneous, and has a very fine granula,r structure ; if, however, the 

 light is reflected in different directions it shows a peculiar glistening, and, 

 very faintly, lines intersecting at angles of about 60O and 120° ; this same 

 iron runs into bands of not over 0.5 '^"' diameter, which, at another por- 

 tion of the iron, intersect at angles of about 00. The space between the 

 bands is filled with an iron presenting a reticulated structure. Dissemi- 

 nated throughout the homogeneous iron are crystals of rhahdite, but few 

 only siiow a regular arrangement. A preliminary analysis gave :

traces of a quartz-like mineral. 



A sulphide of iron of a isale, brass yellow color, and great hardness — 

 probably pyrite is mixed with the iron. Dr. Genth intends to give a fuller 

 account of this interesting meteorite at a future day. 



Dr. Genth also showed specimens of native iron and native lead from 

 the bed-rock of gold-placers, and covered with about six feet of gravel, at 

 Camp Creek, Montana Territory, which have been discovered there by 

 Mr. P. Knabe, who kindly communicated them. 



The native iron is found in small, angular fragments, but slightly 

 coated with rust ; the largest which he has seen is about 0.5 inch in 

 length. Etching with dilute nitric acid does not develop any Widniann- 

 staedtean figures, but a finely granular structure. Mr. Knabe examined
