 Iron. Medium octahedrite (Om), of Brezina. 

 Found 1895; described 1900. 

 Weight, 270 grams (9.5 oz.). 



This meteorite was described by Hidden ' as follows: 



The mass of coarsely crystallized iron here described was first brought to my notice by Mr. J. M. Parfet, of Sal- 

 mon City, Idaho. In a letter dated October 3, 1895, he described its discovery as follows: "The piece of supposed 

 meteoric iron, when first found, was just twice the size of the part I send you. It was kidney-shaped, and in that 

 condition would have been much more valuable (interesting), but the prospector who found it in the bottom of a 

 12-foot shaft on Hayden Creek, Lemhi County, Idaho, just above the United States agency ground, while prospecting 

 for placer gold, wondered what he had found and went to work on it with a 4-pound hammer. This he kept up at odd 

 times for weeks while in camp, and the first time he came down to the Agency shop, he laid it upon the lap of the 

 anvil and with a 14-pound hammer succeeded in bending it in one way, then turned it over and bent it the other way; 

 this he kept up until he broke it in two. Finding it was not a nugget of gold, he had no further use for it, and I got 

 it from him for a trifle. * * * At the time it was broken, the metal showed at the point of fracture to be almost 

 silver white and was quite pretty, but time has oxidized it considerably, and it has lost its luster." 



The above account sets forth the history of the smaller half of this meteorite. Since I recognized it at sight as 

 true meteoric iron, and it was realized that half of it was missing and probably in unappreciative hands, I at once 

 began an inquiry for the missing part. After many months' search, it was traced to the mineral cabinet of Mr. Don 

 McGuire, of Salt Lake City, Utah; and was, after much correspondence, secured by the writer. It is now intact, and 

 has not as yet been analyzed or very critically studied. Its weight is about 9.5 ounces, and it gives evidence of being 

 rich in ferrous chloride (lawrenceite). 



The length of the mass, with the two pieces placed together as closely as possible, is 78 mm. Its greatest width 

 is 33 mm. and its greatest thickness 20 mm. It weighs 270 grams as a whole. 



No other member of this "fall " has as yet been found, though the miners working in the neighborhood of its dis- 

 covery have for several years been on the lookout for them in all the gravel workings. 



The meteorite is distributed: Chicago, 51 grams; Ward, 42 grams.
