The above work is accompanied with engraved brass plates; and his system, which is simple and easy of attainment, may be thus described:--A sheet of paper must first be prepared, with a given number of horizontal rows of small octagons, somewhat resembling the chequers on a draft-board. Straight lines are then to be drawn from the centre towards the sides of these squares, in different positions, and of various lengths, for each letter in the alphabet. Thus, A is a short horizontal stroke, made to the right hand, and not touching the side; E, A, and W, are represented by a similar stroke in the opposite direction, but varying in their lengths. By a similar method the author suggests, in the following article, that we may write with a dot, or single point only, placed in a given situation in the octagon; varying the position for each letter, as is at present done in music, the paper being prepared with ruled lines, or it may be simplified by the use of coloured inks for the vowels and consonants. No. IV. This invention refined, and so abbreviated, that a point only showeth distinctly and significantly any of the twenty-four letters; and these very points to be made with two pens, so that no time will be lost, but as one finger riseth, the other may make the following letter, never clogging the memory with several figures for words, and combinations of letters; which, with ease and void of confusion, are thus speedily and punctually, letter for letter, set down by naked and not multiplied points. And nothing can be less than a point, the mathematical definition of it being _cujus pars nulla_. And of a motion, equally as swift as _semiquavers_ or _relishes_, yet applicable to this manner of writing. NOTE. _Vide_ the preceding article. No. V. A way, by a circular motion, either along a rule or ring-wise, to vary any alphabet, even this of points, so that the self same point, individually placed, without the least additional mark or variation of place, shall stand for all the twenty-four letters, and not for the same letter twice in ten sheets writing; yet as easily and certainly read and known, as if it stood but for one and the self same letter constantly signified. NOTE. The gauge, in this case, must accompany the letter to be deciphered, and, when circular, made to resemble a _map-meter_. By noticing the number of lines passed over by this instrument, and comparing the index-hand with the dots, a sufficiently intelligible though certainly complex cipher may be formed. No. VI.
