ART. 4 SOME FEW METEOKIC IRONS MEREILL 6 



small glistening points are assumed to be schreibersite. On account 

 of lack of information regarding it further investigation was not 

 attempted. Mr. Shannon has, however, made an analysis, the results 

 of which are given in column I below. 



The iron was analyzed by the usual methods on a piece, ground 

 free from scale or inclusions, weighing 11.0383 grams. The composi- 

 tion is shown in column I below :

There is nothing striking in this result, but by a singular coinci- 

 dence Prof. S. W. McCallie (of the Georgia State Survey) has but 

 recently reported an iron found at a locality called Social Circle 

 in his State that presents an almost identical appearance and granu- 

 lated etched surface. The composition (column II above) agrees 

 so closely that both analyses might have been thought made from 

 the same mass except for the 0.09 per cent of tin, which is perhaps 

 open to question.

 This iron was brought to my attention by Stuart H. Perry, of 

 the Adrian Daily Telegram, with the statement that it was found 

 in July, 1923, and that it is supposed to be the result of a fall seen 

 at Seneca Township in 1914. The evidence thus far submitted can 

 not, however, be considered as altogether confirmatory. 



As shown in the plate (pi. 2, upper), the mass is in the form of a 

 flattened oval, and though oxidized and scaling somewhat on the 

 outer surface still shows traces of the larger original thumb mark- 

 ings. That it has lain exposed for some years is unmistakable. The 

 present weight is 11.5 kilograms. An analysis by E. V. Shannon 

 in the Museum laboratories yielded :
