148. In the following table all substances which crystallize 
on the cubical system are arranged according to their chemical 
formulas; the letters c, o, and d, representing that faces parallel 
to the cube, octahedron, and rhombic dodecahedron, occur on 
their crystals. The crystals having faces parallel to other 
forms have been previously enumerated under those forms. 
The table is principally taken from Rammelsberg's Crystallo- 
graphic Chemistry.
