PERRYVILLE, PERRY COUNTY, MISSOURI. No. 428. 



Iron, Off. Nearly complete individual weighing when received 

 17.386 kilograms, or about 38] pounds. (Pis. 29 and 30.) Two sur- 

 faces etched. Original weight estimated to have been 17.5 kilograms. 

 Found August, 1906. Date of fall unknown. The iron is noted for 

 its extreme, fine crystallization. Analysis by Whitfield yielded 

 results as below: 



Per cent. 



Iron (Fe) 89.015 



Nickel (Ni) 9. G60 



Cobalt (Co) .545 



Copper (Cu) .025 



Mnnganese (Mn) None. 



Phosphorus (P) .365 



Sulphur (S) .002 



Silicon (Si) .003 



Carbon (C) .015 



Ferric oxide (Fe^Os) -370 



Iridium 



Palladium 



Platinum 



Kuthenlum 



Traces. 



100. 00 



Specific gravity, 7.61. 



This iron is of interest on account of the careful search made for 

 the rarer elements, of which iridium, palladium, platinum, and 

 ruthenium were found in traces, the last named being reported for 

 the first time. The schreibersite separated out in process of analysis 

 yielded : 



Per cent. 



Phosphorus (P) 1-1.00 



Iron (Fe) 5L 10 



Nickel (Ni) 34.13

 8 pounds 3 ounces. Original weight as found in 1893, 11 pounds 3 

 ounces, or a trifle over 5 kilograms (pi. 31). Nothing known as to 

 date of fall. A brecciated mass of variously oriented fragments of
