Then to represent any number, let the first letter be a vowel or diphthong, the second a consonant, the third a vowel, the fourth a consonant, &c. Thus for the number 1763, you write or remember the word akaud; if there are several sums to be retained, you place the words in form of verses—which will make them more pleasing to repeat and more easy to remember; for example, if you would remember the dates of the discovery of America by Columbus, the settlement of Virginia by Captain Smith, the landing of the Pilgrims at Plymouth, the Battle of Bunker Hill, the Declaration of Independence, and the Battle of New Orleans, which were in 1492, 1605, 1620, 1775, 1776, and 1815, you write as follows—for you are to observe that in this, as well as similar cases, when the first figure is always the same, it is unnecessary to write it after the first time:

Afouc hyh hen keag keah lag.

When several cyphers come together, instead of repeating y or n, you may write y or n 2, 3, &c.; thus, for 3400, write ify2, and for 256,000, write ehun3.

To remember any number of words, select the initial letters of those words, and to the first add a, if it begins with a consonant, or b, if it begins with a vowel. In like manner e or c to the second initial letter; to the third add i or d; to the fourth o or f; to the fifth u or g, so that of the five initials you make five syllables, which are joined together in one word—then of the next five initials you make, in the same manner, another word, and of every two words you make a verse; for example, suppose you would remember the names of all the kings of England since the Norman conquest in the order in which they reigned, you then write as follows:

Wa we hi so hu Ra je hi ef eg
Eb re hi ho hu Eb ec ri ho hu
Eb me ed jo cu Ca je wi af gu Ga ge gi go wu Va.

Or, if you would remember the letters that begin any number of verses, suppose the twenty first lines of Pope's Essay on Man, you write as follows:

Abtelitoeg Abacodtotu
Taocedaflu Basewioffu.

THE MAGICIAN'S MIRROR.

Construct a box of wood, of a cubical shape, A B C D, of about fifteen inches every way. Let it be fixed to the pedestal P, at the usual height of a man's head. In each side of this box let there be an opening, of an oval form, ten inches high, and seven wide. In this box place two mirrors, A D, with their backs against each other. Let them cross the box in a diagonal line, and in a vertical position. Decorate the openings in the side of this box with four oval frames and transparent glasses, and cover each with a curtain so contrived as all to draw up together.
