What is the relation of the axes in the right prismatic system ?In the oblique prismatic, what is it ? SYSTEMS OF CRYSTALLIZATION. 207 THE DOUBLY OBLIQUE PRISMATIC SYSTEM has three… … prisms, and 3 and 4 doubly oblique octahedrons. THE RHOMBOHEDRAL SYSTEM has four axes, three of which are equal in the sameplane, and inclined at angles of 60°; the fourth, whichis the principal axis, is perpendicular to all.
