...Thus, the symbol {hkl} will be used to express the form bounded by the face (hk I) and its coexistent faces. The " holohedral forms " of any system are...forms, is called a " combination" of those forms. 35. The elements of a crystal are the inclinations of the axes YZ, ZX, XY, and the ratios of two of...

In the present case, however, I propose to treat this subject...

...CLASSIFICATION OF CRYSTALS. FIG. Homohedral, or Holohedral forms, are those which, like the cube and octahedron, possess the highest degree of symmetry of which the system admits. Hemihedral forms, on the other hand, are those which may be derived from a holohedral form, as the tetrahedron is from...
