Wadsworth describes the stone as consisting of a light-gray chon- 

 dritic mass containing grains of iron and pyrrhotite in a gi'ound- 

 mass composed of olivine, enstatite, and some diallage.

Iron, Om. Two slices, weighing 10.3 and 17.7 grams, respectively,

PUTNAM COUNTY, GEORGIA. Nos. 51, 264. 



Iron, Of. Found in 1839; date of fall unknown. Two pieces; 

 one of 328 grams, somewhat oxidized, but showing cleavage plates 

 separated by taenite, and one 10 cm. by 19 cm. by 25 cm., weighing 

 2,455 grams, with one face etched, showing small troilite nodule and 

 a cleavage octahedron on one side (pi. 31). Composition, as shown 

 by analyses of R. Knauer and O. Biirger, as follows: 



Per cent. 



Iron (Fe) 90.28 



Nickel (Ni) 7.89 



Cobalt (Co) .79 



Copper (Cu) .07 



Chromium (Cr) .17 



Sulphur (S) .25 



Phosphorus (P) .11 



99.56 

 Considering the chromium as a constituent of the mineral daubree- 



lite, the following is given as the probable mineral composition of 



the mass: Nickel-iron, 98.69; schreibersite, 0.73; daubreelite, 0.47; 



troilite, 0.11.

Stone, Cc. Fragments, weighing 17 grams, from one of three 

 fragments which fell December 27, 1857. This fall is of interest in 

 that the stone broke so low in the atmosphere that the fractured sur- 

 faces were not all re-fused, and the three pieces could be fitted 

 together, proving their common origin.
