in color. The stony meteorites are usually of a grey or greenish 
gtey color, granular structure, readily broken by a blow of the 
mer, and exteriorly are covered with a thin coating of fused 
material. The mixed meteorite presents characters of both of the 
above ; a large portion of it is constituted of the kind of iron al- 
teady mentioned, cellular in its character, and the cells filled up 
with stony materials, similar in appearance to those constituting 
the second class. 
Although there are some- instances of bodies of undoubted 
Meteoric origin not properly falling under either of the above 
three heads, still they will be seen upon close investigation not te 
interfere in any way with the general conclusions that are at- 
tempted to be arrived at ; for these constituents are represented in 
the stony materials of the second class from which their only es- 
sential difference consists in the absence of metallic particles.
