No. XXI.—A MOORISH MAGIC SQUARE

Among Moorish Mussulmans 78 is a mystic number.

40	10	20	8
7	21	9	41
12	42	6	18
19	5	43	11

Here is a cleverly-constructed Magic Square, to which this number is the key.

The number 78 can be arrived at in twenty-three different combinations—namely, ten rows, columns, or diagonals; four corner squares of four cells; one central square of four cells; the four corner cells; two sets of corresponding diagonal cells next to the corners; and two sets of central cells on the top and bottom rows, and on the outside columns.
