certain, however, and it seems desirable therefore to group them sep- 
arately. Their percentage of nickel-cobalt resembles that of the 
finest octahedrites, 11 to 15 per cent.

accord with octahedral planes. In the meshes of this web’ the 
nickel-poor remainder is deposited as a homogeneous, granular 
aggregate. If the structure is secondary, it may be explained by 
supposing that a normal octahedrite was somewhat softened by heat, 
so as to destroy the lamellar structure in part, after which solidifi- 
cation took place. If this latter be the correct explanation, the 
softening was carried farther in Hammond than in Cacaria and Reed 
City.
