near some portions of its surface. The amount of oxide on the 
surface is small, the cut surfaces showing bright metal quite up 
to the exterior surface. The Widmannstittian gures de- 
veloped are of that class where the lines are delicate and 
straight, inclined at a considerable angle to each other, a ee
