realized, and the description here given rests upon an examination 

 of the fragment first received. 



The fragment is beautifully pitted and coated with but a very thin 

 brownish crust, little oxidized, testifying to the supposed recency of 

 its fall. A polished surface shows it to be a medium octahedrite, but 

 of more than ordinary interest from the fact that along one end is 

 a curving border of a maximum thickness of 7 mm. of a distinct, 

 finely granular structure into which the typical octahedrite figures 

 pass gradually (fig. 1, i)l. 1). It is plainly a case of natural heat 

 granulation during flight — the metabolite structure of Berwerth — 

 which, so far as I recall, has been exemplified only in the case of 

 the iron of Charlotte, Dickson County, Tennessee. A natural infer- 

 ence is that this portion represents the hrustseite of the iron during 

 its flight. The small amount of the material at my disposal prevents 

 as complete a chemical examination as might be desired. A 10-gram 

 fragment containing no visible troilite, carbon, or schreibersite segre- 

 gations yielded Doctor Whitfield : 



Per cent. 



Silicon 0. 004 



Sulphur 0. 002 



Phosphorus 0. 041 



Nickel 7. S60 



Cobalt 0. GOO 



Copper 0.015 



Iron 91. 470 



Total 99. 992 



These figures present no features not common to octahedrites, or 

 that in themselves alone would serve to distinguish this from numer- 

 ous others that might be mentioned belonging to the same group. 



COLD BAY, ALASKAN PENINSULA. 

 (Cat. Nos. 633, 686, U.S.N.M.) 



The meteorite (pallasite) described below was brought to the 

 writer's attention by Mr. S. R. Capps, of the United States Geological 

 Survey, who reported : 



This meteorite was found in June, 1921, on a mountain top about three 

 west of the trading post at Cold Bay on the Alaskan Peninsula. When found it 

 was perhaps as large as a man's two fists. It was broken into fragments and 

 a large part of it, at least, was lost before I discovered it was a meteorite. It 

 is possible that there are a few fragments in existence. I will try and reach 

 the man who may have them and obtain them for the Museum. 



The small fragment (weight 40 grams) which Mr. Capps had 

 saved and brought to the Museum, although badly oxidized, was 

 sufficient to show at once its meteoric nature. On learning of its de- 

 sirability Mr. Capps wrote to one of the parties mentioned and sue-
