It often happens, owing to a change in the deposit ofnew matter on a crystal while forming, that other figuresthan the proper one are produced ; thus, the cube maypass into the octahedron, as shown in Fig. 140. How many axes arc in the rhornbohedral system, and what is their re-lation ? In what manner may crystals of one fomi pass into those ofanother, as the cube into the octahedron ?
