THREE NEW CHILIAN :METE() RITES. 229 



information as to its locality was given on a label, which stated 

 that it was brought by Herman Schneider, a student from Val- 

 paraiso, from Ilimae, about 26° S. latitude and 70° W. longitude." 

 Now, as this locality is geographically the same, it is undoul^tedly, 

 as Fletcher has noticed, a question of misspelling. 



The distance to Imilac from Ilimaes is about 170 miles in a 

 northeasterly direction. Other pallasite fragments of the Imilac 

 group have been found still further north and northwest. A 

 meteorite was, indeed, found in 1861, at Vaca Muerta, which is 

 about 40 miles west-of-north of Ilimaes, and another in 1875, at 

 Taltal, which is nearly the same distance to the north. But the 

 former of these was a mesosiderite of the Grahamite group, and 

 the other an aerolite, of which little is known. This still leaves 

 the Ilimaes meteorite isolated by 160 or 170 miles from any other 

 recorded pallasite locality. This distance, too great for the prob- 

 able limits of a straggling member of a meteorite fall, adds further 

 support to the differences in microscopical character, as before 

 noticed, in considering our meteorite as distinct from Ilimae, and 

 calling it from its place of find, — Ilimaes. 



COBIJA. 



In a short visit to the School of Mines in Santiago de Chili, 

 in April of 1905, I was shown by Sefior Julio Laso, the Mineralo- 

 gist and Custodian of the Collections, two meteorites, a stone and 

 an iron, which he informed me were new to science, having never 

 been closely examined or described. One of these was found by 

 Professor Laso himself, in February, 1892, on the pampa of Santa 

 Barbara, in the Department of Antofogasta, a short distance east- 

 ward from the town of Cobija. The mass (Plate 25, fig. i), which 

 had the shape of a lengthened sphere, was about 14 x 12^ x 11 cm. 

 in length, breadth and thickness, or about the size of a child's 

 'head. One side of the sphere was flattened, so that sections of 

 the mass were of a certain horseshoe shape. One end is also 

 flattened. Half of its surface, with a narrow strip leading along 

 at right angles on one side, has a well-developed crust with a 

 granulated pitting. The' exterior surface of the main spherical 

 portion of the mass shows a tendency to flake or shell ofif, although 

 still firm in texture. This character is also manifest on the flat
