For _seven_ letters (adding k) I add, to each upright cross, a little
inner square. All these 16 little squares are assigned to the k-Class,
and all outside them to the k'-Class; so that 8 little Cells (into which
each of the 16 Cells is divided) are respectively assigned to the 8
Classes ehk, ehk', &c. We have now got 128 Cells.
