The Tetragonal system, or The Dimetric system has a varying vertical axis, while the lateral are equal, as in the right square prism. 3. The Orthorhombic system, or The Trimetric system has the three axes unequal, as in the rectangular and rhombic prism. In this system, the lateral axes are called, respectively, macrodiagonal and brachydiagonal. -- The preceding are erect forms, the axes intersecting at right angles. The following are oblique. 4. The Monoclinic system, having one of the intersections oblique, as in the oblique rhombic prism. In this system, the lateral axes are called respectively, clinodiagonal and orthodiagonal. 5.
