“Z. The Z. in an oblique line downwards passing the right corner line of the square.

“The Chequers are five in number, which of either outside show the vowells, and each Chequer haveing two corners inwards of each side make tenn, those towards the preceding square may conteyne of the 24 letters, and the opposite corners as many Alphabetically, and the centers of the two upper Chequers square, and of the two lower shew the other 4 letters; The 20 in the Chequers are noted by a separation of a corner in the printed Alphabett, and the 4 by the midde points.

“It is for curiosity and secresy to bee deservedly observed that whether in squares or chequers single points only stand for letters, and they being varyed att pleasure, it is in any ones power to keepe his secrett from me or any other not made acquainted with the denominations by him given to the severall points, and accordingly by him marked in the 24 blank squares, and rowes of chequers placed under the Alphabett in his private explanation easily to be framed by him mutatis mutandis, only that is making the questions and resolves according to his points as they represent the letters to his owne fancy keept private from others without his consent.

“The points are to bee written, and reade as they precede, or as they are the one above the other, unlesse they have a sequell distinction made by takeing the penn of the paper thus ^✓ without further losse of tyme, and such as are soe marked, must be written and read as the others they being soe made, but for husbanding of paper, the word being soe conteyned in lesse roome, the e at the end of most words prolonging butt the sillable, and all needlesse and unsounding letters are to bee omitted; I will not trouble you with more rules leaving the rest to practice.”

The preceding description is written on small oblong pages, which measure 11¼ by 7¼ inches, the whole surface of the unwritten portions being covered with an engraved pattern, of which Fig. 1 is but a portion of the top left-hand corner, and therefore proceeds no further than letter h, which ends the application of that particular figure.

Fig. 2. Gives the next form for 8 other similar situations, commencing at i. And—

Fig. 3. Is again 8 more, commencing at r; making in all 24 characters or letters.

We thus see how, whether by a dot, or a short line of three gradations in length, an entire alphabet may be obtained.
