n exposure to the air, it deliquesces, yielding chlorid of iron ; 
but this does not prove chlorine to have been an original ingredi- 
ent of the stone, since the mass, as in the case of one of the 
lowa (Feb. 25, 1847) stones, may have been since its fall in some 
situation where chlorine has been imparted to it. 
Its specific gravity is 3°38. It contains 15-07 per cent. of 
nickeliferous iron, with traces of sulphur. The stoney part con- 
sists of silica, magnesia, protoxyd of iron, alumina and lime.

Crust thick, sometimes one-third of an inch and consists of mixed 
oxyds of iron, somewhat coated by blue phosphate of iron, (vivi- 
auite.) In moist air, the chlorid of iron deliquesces in little 
drops, | It does not afford the Widmanstittian figures. It does 
0 nickel, cobalt, or sulphur.
