The Chabasie here figured belongs also to the Royal Institution. It shows the acute angles of the rhomb truncated, which is sometimes one of the characters, and also the lateral edges;—see the left hand figure. Occasionally the other edges are truncated. The right hand figure is one half of this repeated in the same direction, and the other half turned upon it till the truncations meet. The striæ pointing to the obtuse angles may denote the summits; and by directing the eye so as to view it in that direction, it may be understood as well as when viewed in the usual position of the plate. The crystals vary much in their position in the group, and the lustre so peculiar to them gives them an indistinct appearance, making them less easily understood.
