It has been already observed by Dr. Wollaston, that the cleavages of the crystals of this salt are parallel to the lateral planes and diagonals of either a rectangular or a rhombic prism. From the figures and measurement of seve- ral crystals, I am indncedto adopt the right rhombic prism as the primary form. The annexed figure represents the planes which occur on many of the crystals placed symme- trically in relation to the primary planes.
