While in this paper Kunz expressed the opinion that this meteorite belonged to the same fall 

 with the irons from the Ohio mounds, in a later paper 4 he withdrew this conclusion on account 

 of the structure of Eagle. 



Meunier 3 gives a brief account of the study of the meteorite, but elicits no facts of importance. 

 Brezina, 5 in his 1895 catalogue, classes Eagle in the Rokicky group, the characteristics of which 

 are polyhedral olivines broken and separated by movement of the inclosed iron. Of Eagle he 

 remarks that it — 



is one of the most beautiful and interesting meteorites in consequence of the freshness of its olivine and the peculiar 

 faulting. The iron borders the olivine generally in the form of complete lamellae, a strong tsenite ribbon lying adjacent 

 to the olivine. The iron in the interior is separated into differently oriented parts by wavelike, bent bands of tsenite. 

 No actual trias is visible, but here and there in the interior of the iron appear groups of fine lamellae like those of Butler. 



The meteorite is distributed, but is chiefly (18 kg.) in the Vienna collection.

EL CAPITAN. 

 El Capitan Mountains, New Mexico. 

 Latitude 33° 40' N., longitude 105° 17' W. 

 Iron. Medium octahedrite (Om) of Brezina. 

 Found 1893; described 1895. 

 Weight, 27.5 kgs. (61 lbs.). 



This meteorite has been described only by Howell * as follows: 



This handsome meteorite was found by a Mexican sheep herder, Julian Jesu, in July, 1893, on the northern slope 

 of the El Capitan range of mountains in New Mexico. Three small pieces were broken from the thin edge which show 

 beautifully the octahedral structure of the iron. The smallest of these, weighing a few ounces, was sent to the United 

 States National Museum, and the two larger, weighing respectively 1 pound 12.5 ounces and 3 pounds 14 ounces 

 together with the main mass, 55 pounds, came into my possession at different dates in 1894. The weight of the iron 

 when whole was about 61 pounds; the general shape is shown by cuts. It measured 10 by 9 by 5 inches, thinning at 

 one edge, and had the usual irregular pitted surface. My information in regard to the history of the meteorite, as well 

 as the meteorite itself, was obtained from Mr. C. R. Biederman of Bonito, New Mexico. Mr. Biederman says that he, 

 in company with many miners, was standing in front of a store in Bonito some time in July, 1882, when they saw "a 

 meteorite which looked like a fiery ball moving rapidly toward the south at an angle of 45° which vanished, behind the 

 El Capitan range." Mr. Biederman thinks the meteorite found by the Mexican is the one they saw fall, and there is 

 nothing in its appearance to disprove his claim. It is entirely free from oxidation and evidently fell at a comparatively 

 recent date. The Widmannstatten figures are developed very easily and clearly and indicate that it belongs to the 

 usual type of octahedral irons with rather broad bands of kamacite.
