DlTTMARlTE. 



A very doubtful mineral species (R.). 

 Dolomite. — Magnesium carbonate. 



Small, white, flat rhombohedra with rounded faces, the whole 

 forming a small cavernous mass, from the basalt, Buiig 

 Bung* (W.). White nodular masses, Swift's Creek (CI.). 

 Edmondsonite. — A meteoric nickel-iron. 



This alloy forms thin paper-like pliant plates, which lie on 

 the faces of the tetrahedra of nickel-iron. They are in 

 the form of equilatei-al triangles, or are lozenge-shaped, 

 and have the thickness of stout writing paper. Fresh 

 plates taken direct from the meteorite contained 0.688 per 

 cent, of phosphorus. Cranbourne No. 1 Meteorite (F.).
