Mag. for Sept. 1831, Mr. Brooke has given the form and angles of a mineral from Vesuvius which he received as wollastonite. This particular specimen has not been ana lyzed, but it resembles others received in this country under the same name. The fragment figured by W. Phiilips as tabular spar was taken from a specimen stated on its ticket to be from Vermont, U. S. The supposed tabular spar is in large grains, and is accompanied by small grains of coccolite ; but we do not find any notice in the American works on Mineralogy of such an association of minerals having been found in Vermont. 161.
