This very ingenious mode of secret writing is the most simple of any suggested by our author. A silk string of considerable length having been provided, it will be necessary to furnish the persons corresponding with a key or graduated gauge, by means of which the writing will be rendered intelligible. Having procured a duplicate or corresponding gauge it may then be commenced, 1/16 of an inch being allowed for the first letter, 1/4 for the second, 3/8 for the third, and so on, in equal proportions, through the whole alphabet. Should this arrangement be found to extend the line to an inconvenient length, it may be advisable to form a certain number of changes on three different lengths, as in No. LII.; though the former way is the least difficult. No. XXXV. The like by the fringe of gloves. NOTE. The principle of this and the four following Articles is the same as the preceding, with this difference, that in the first, the letters, or words, are formed by knotting the fringe, to which the gauge is afterwards applied; in the second, and most desirable way, the beads are set to the required distance; by the third, the gloves are pierced or pricked in rows, according to the divisions on the gauge; and by the fourth and fifth, the rows of parallel holes in a sieve or lantern are stopped at the required distances, and the gauge applied as before. No. XXXVI. By stringing of bracelets. No. XXXVII. By pinked gloves. No. XXXVIII. By holes in the bottom of a sieve. No. XXXIX. By a lattin or candlestick lantern. No. XL. By the _smell_. NOTE. Pegs of sandal, cedar, and rose woods, may be so varied, that a person writing in the dark will, by the smell, readily distinguish the formation of words and sentences. No. XLI. By the _taste_. NOTE. For writing by the _taste_, it will be necessary to immerse an equal number of the pegs or beads in weak solutions of alum, aloes, common salt, or any other liquid whose taste is sufficiently pungent or aromatic, to be distinguished when dry, on applying the tongue to them for that purpose. No. XLII. By the _touch_. By these three senses, as perfectly, distinctly, and unconfusedly, yea, as readily as by the sight. NOTE. This object may be readily attained by the use of raised moveable types and the heavy pressure of an iron pen or mallet.
