276 G. F Kunz — Two new masses of Meteoric Iron. 



exhibit beautiful octahedral markings so delicate as to be in- 

 visible to the naked eye, and somewhat like those of the Taze- 

 well, Claiborne Co., meteorite, though not more than one-tenth 

 the thickness. 



The following analysis was kindly furnished by Mr. J. 

 Edward "Whitfield, of the United States Geological Survey, 

 through the courtesy of Prof. F. W. Clarke.

It most closely resembles the Tazewell, Claiborne and Bear 

 Creek, Col , meteorites in composition. I herewith take pleas- 

 ure in thanking Mr. Gorman Spang for his kindness in allow- 

 ing me to secure the iron and facts of finding, Mr. J. Edward 

 Whitfield and Prof. F. W. Clarke for the analysis. 



2. Meteoric Iron from Laramie County, "Wyoming. 



The Laramie County mass of meteoric iron J was found. 

 by Mr. Edward J. Sweet, in the latter part of January, 1887, 

 while he was prospecting in the Silver Crown District, almost 

 in the center of town 14, range 70, between the middle and 

 south fork of Crow Creek, Laramie County, Wyoming Terri- 

 tory, about 21 miles west of Cheyenne, in long. 105° 20' west 

 of Greenwich and north lat. 11° 10'. When found it was half 

 buried in decomposed granite and earth. After being a ten 

 days' wonder among the miners at the camp it was sent to Dr. 

 Wilbur C. Knight, of Cheyenne, Wyoming, through whom it 

 came into my possession. 



In shape this mass somewhat resembles an anvil (see fig. 3, 

 two-thirds natural size). It weighs 25*61 lbs., 363 oz. Troy 

 (11-616 kilos.) ; and is 17*o cm high, ll cm thick at the center and 

 19 cm at the widest point. The entire surface is still covered 

 with the original crust of magnetic oxide of iron, which has 

 been slightly acted upon by the atmospheric agencies. ~No 

 trace of chloride of iron was perceived. There is no exuda- 

 tion although it has been in my possession some months. The
