e away half of thirteen and let eight remain.

Write XIII on a slate, or on a piece of paper--rub out the lower
half of the figures, and VIII will remain.

Upon the principle of the square-words, riddlers form Diagonals,
Diamonds, Pyramids, Crosses, Stars, &c. These specimens will show
their peculiarities:

66. Oblique Puzzle.

Malice, eight, a polemical meeting, a Scottish river, what I write
with, a decided negative, the capital of Ireland. The initials
downward name a celebrated musician.

(solution in p.67 below.)

67. Diagonal Puzzle.

A direction, a singer, a little bird, a lady's ring, a sharp shaver.

Read from left to right and right to left, the centrals show two
famous novelists.

The following are answers to these two puzzles, and afford good
examples of their construction to any one who wishes to try his hand
at their manufacture.

68. Diamond Puzzle.

The head of a mouse, what the mouse lives in, the county of calves,
the city of porcelain, a German town, a Transatlantic stream, a
royal county, a Yorkshire borough, Eve's temptation, our poor

river.

The construction of the Diamond Puzzle is exhibited in the following
diagram, which is, at the same time, the answer to it.

additions to words. Dr. Johnson, however, represents Rebus to be a
word represented by a picture. And putting the Doctor's definition and
our own explanation together, the reader may glean a good conception
