FRANKLIN COUNTY (KY.) METEORIC IRON: 



WITH EEMAEKS ON THE PRESENCE OE COPPER AND 

 NICKEL IN METEORIC IRONS; THE METHOD OE ANALY- 

 ZING THE SAME; AND THE PROBABILITY OE THE LEAD 

 IN THE TARAPACA IRON HAVING BEEN ORIGINALLY 

 EOREIGN TO THAT MASS. 



1. The Franklin County Meteoric Iron. 



The Franklin County meteoric iron was first brought to my 

 attention in a blacksmith -shop in Frankfort, Ky. It was car- 

 ried there to be tested in regard to its quality as iron ; being 

 supposed by its discoverer to indicate an iron-mine. Mr. Nelson 

 Alley became possessed of it, and kindly presented it to me. 



It came from a hill eight miles south-west of Frankfort, 

 latitude 38° 14' north, longitude 80° 40' west from Greenwich, 

 and was discovered in 1866. It passed into my possession in 

 1867, and was then described by me, but the manuscript was 

 lost after its leaving my hands, and the original notes were 

 misplaced; the notes have been recently discovered, and the 

 iron again anatyzed. 



Its form is somewhat globular, with a highly crystalline 



structure. Its weight was twenty -four pounds; and this 



appears to have been its original weight, only a few flakes 



having become detached by the rusting through of some of 



the fissures. Specific gravity 7.692. Its composition when 



perfectly freed from rust and earth is 



Iron ....90.58 



Nickel 8.53 



Cobalt 36 



Copper minute quantity. 



Phosphorus 05 



99.52 

 Having, as it will be seen, the usual composition of meteoric 

 irons. While on the subject of this iron I will add some 

 remarks.
