Abstract
I THINK “plane-direction” is the best of the competing names. The planes of cleavage in a crystal are the “plane-directions” in which it is most easily split. They cannot be called either “aspects” or “positions.” The opposite faces of a cube certainly cannot be said to have the same “aspect.”
