ROEBOUENE (about 200 miles southeast of), NORTHWEST AUSTRALIA. Nos. 453, 490. 



Iron, Om. Slice 50 by 50 mm., weighing 237 grams, and slice 60 

 by 80 mm., weighing 145 grams, gift of F. Hess. From a mass weigh- 

 ing 191.5 pounds, or 86.8 kilograms, found in 1894. The chemical 

 composition as determined by Mariner and Haskins is : 



Per cent. 



Iron (Fe) 90.914 



Nickel (Ni) 8.330 



Cobalt (Co) .590 



Phosphorus (P) -156 



Sulphur (S) Trace. 



Manganese (Mn) ?Trace. 



Silicon (Si) -01 



Carbon (C) Trace.

ROWTON, WELLINGTON, ENGLAND. No. 86. 



Iron, Om. Slice 4.2 by 1.2 cm. weighing 19.5 grams, from a mass 

 weighing 3.5 kilograms or 7| pounds, which fell on April 20, 1876. 

 Composition as shown by analysis: 



Per cent. 



Iron (Fe) 91. 2.50 



Nickel (Ni) 8.582 



Cobalt (Co) .371 



Copper (Cu) Trace.

The iron sulphide was also analyzed and found to be troilite. Gas 

 was determined to the amount of 6.38 times the bulk of the iron, hav- 

 ing the following composition: 



Per cent. 



Carbonic acid (CO2) 5.155 



Hydrogen (H) 77.778 



Carbon monoxide (CO) 7.345 



Nitrogen (N) 9-722 



100. 000 



The great interest in this iron lies in the fact that it is one of the 

 nine irons which have been seen to fall.
