Now place the nine digits round the sides of each of the triangles, so that their sum on each side may be 20, and so that, while there are no two triangles exactly alike in arrangement, the squares of the sums on the other sides may be alternately equal.

A PERSONAL ENIGMA
We can but see his sad reverse,
And while we say alas!

No. XXXV.—A MAGIC CROSS
There are 33 different combinations of four of the numbers in the cells of this magic cross which total up in each case to 26.
| 1 | 12 | ||
| 9 | 8 | 5 | 4 |
| 2 | 7 | 6 | 11 |
| 10 | 3 |
Those who care to work them out on separate crosses will find that there is a very regular correspondence in the positions which the numbers occupy.
