nickel, 7.040. Subsequently Dr. John M. Davison found traces of 

 platinum. Specific gravity, 7.853. This iron is remarkable for the 

 large masses of dendritic schreibersite it contains. (See pi. 12, 

 fig. 2.)

ARLINGTON, SIBLEY COUNTY, MINNESOTA. No. 492. 



Iron, Om. A thin slice 60 by 20 mm. and weighing 24 grams, from 

 a mass weighing 19| pounds, found in 1894. An analysis by F. F. 

 Sharpless yielded: 



Per cent. 



Iron (Fe) 90.781 



Nickel (Ni) 8.605 



Cobalt (Co) 1.023 



Phosphorus (P) .045

No sulphur, silicon, or manganese, and but traces of chromium, 

 copper, and carbon.

AUBURN, LEE (FORMERLY MACON) COUNTY, ALABAMA. No. 35. 



Iron, H. AVeight 23 grams. Date of fall unknown, the mass be- 

 ing ploughed up in a field " many years " prior to 1869. The iron as 

 found was described by C. U. Shepard as cracked up and subdivided 

 by open veins as if it had been shattered by striking against a rock at 

 the time of its fall. The cohesion was so imperfect that it could be 

 broken into small pieces by means of a sledge hammer, and a very 

 large portion of it has been lost. The chemical composition as 

 given is: 



Per cent. 



Iron (Fe) 94.58 



Nickel (Ni) 3.015 



Phosphorus (P) .129 



Insoluble . 523
