MEMOIR ON METEORITES. 



in some parts little blisters existed, arising from chloride of iron. 

 Portions of the broken surface retain their metallic luster un- 

 tarnished. The Widmannstattian figures are very imperfectly 

 developed, owing to the porous nature of the iron, the pores 

 of which are filled with a stony mineral. The specific gravity 

 taken on three specimens were 6.52, 6.91, 7.13. The last was 

 the most compact and free from stony particles that could be 

 found, and upon that the chemical examination was made.* 



Fig. 3. 



On examination it is seen to consist of two distinct parts, 

 metallic and stony. The latter was only in minute particles, 

 yet it was impossible, among the specimens at my disposal, to 

 find a piece that was without it. On analysis the following- 

 ingredients were found: 



Iron 85.54 



Nickel 8.55 



Cobalt 61 



Copper 03 



Phosphorus 12 



Chromic oxide 21 



Magnesia 2.04 



Silica 3.02 



Alumina trace 



Which represent the following min- 

 erals: 



Nickeliferous iron 93.81 



Chrome iron 41 



Schreibersite 84 



Olivine 5.06 



100.12 



100.12 



*This iron is now in the Smithsonian Institution, as has been for several 

 years. April, 1873.
