H, A. Ward — Canyon City Meteorite. 



size, ranging generally from 1 to 2 mra in diameter, with an 

 occasional broader one of from 3 to 4 mm , as will be seen in the 

 cnt. The bands of tsenite are broad and quite prominent 

 throughout the mass, the plessite in many places showing these 

 bands crossing them in parallel layers (Laphamite markings). 

 This is shown particularly well on some of the edges of the 

 slices which have been oxidized, giving the tsenite a somewhat 

 comb-like effect from their relief above the weathered kama- 

 cite. 



No schreibersite was noticed by a macroscopical examination. 

 The largest troilite nodule found in any of the sections is not 

 over 2 mm in diameter ; others range from this down to a fraction 

 of a mm. These latter were quite abundant, as many as sixteen 

 of them being scattered over some of the slices. On the nar- 

 row end of three of the slices is a fissure, entirely crossing the 

 slice, filled with troilite. 



Some sections show that the oxidation of the surface had 

 extended inward to the depth of 5 mm in some places. This 

 readily accounts for the non-appearance of crust on the exterior 

 surface of the mass, as well as the tendency in some portions 

 to scale ; also for the limonitic color of the whole. 



The examination of this iron by Prof. Shepard, as noted in 

 the article above referred to, was limited to two small pieces — 

 barely an ounce in all — which were from the outer surface, and 

 "had the appearance of pure limonite." It was thus, as he 

 suggesfs, difficult to obtain either an exact analysis or exact 

 specific gravity. This circumstance sufficiently accounts for 

 the difference between his analysis and the one lately made by 

 Mr. J. M. Davison of Rochester, N. Y. We give both below :

We have given the name of Canyon City to this iron. The 

 town of that name no longer exists, but was known when Prof. 

 Shepard wrote his paper. Mitchell's Atlas, edition of 1885, 

 has Canyon City on the right bank of a branch of Trinity 

 Piver in the center of Trinity County, lat. 40° 55' N., Ion. 

 123° 5' W. It is satisfactory to be able to thus see rescued from 

 the oblivion of uncertainty a meteorite which for more than a 

 quarter of a century has been mistily known by name yet 

 absent and unknown in substance.
