to be observed, that
the interior alphabet may begin with A; but the writing will perhaps result in
being better hidden, if we throw the letter A into the last square.

The fourth
table, taken from de Vigenere, p.202b, has
this peculiarity, that we may here write with vowels only. The use and praxis of these four tables is as follows: Place before your eyes a written text, whatever it be that you wish to conceal; e.g. this sentence: Germania discors. Now look for the square, or space, |

wherein is contained the letter G. When this has been found, take this letter first which is written on the same line, straight across. Next, take as the second letter that which is written in horizontal capitals, directly above. These two letters put down and write on paper, to express the letter G. Thus, if you follow the first table, the letters Acc will result; if the second table, the letters qg: if the third table, the letters bb; if the fourth table, the letters ee. The complete example of the aforementioned sentence, adjusted to the third table, is this: Bbdacdbcdeccdbdecadbddbadccddd. For the rest, this Mode may be varied, in that we may begin to write with the capital letter in the horizontal line, just as we have up to this point begun with the perpendicular line of letters. Further, there is a special use of the second table, depending on the numerical signs, -- a use I will consider in its proper place, Bk.6.c.19. similarly, in the case of the last table, there is a special use, connected with the first table in Chapter Eleven, above, which use is this: In accordance with the device given in this chapter, the following or a similar sentence is transposed: Omnia conando: Joieiieouo aeioiiuoiiaiio. These vowels are mingled in different ways, according to your pleasure, with the example (which is xstqcs &c.) transposed by the aforementioned first table; thus, stqiocszlicscqgeq&&qiibchxeo &c. This method of hiding the secret is worthy of all praise. For, since in the principal example, involved by the first table, no vowels appear, the suspicion arises that some of the consonants take the place of vowels. That such suspicion may not arise, and that the writing may be made as involved as possible, some other sentence must be transposed by the device given in this chapter, and, as previously explained, intermingled with the other. One may accomplish the same result by constructing the first secret from four of the Idle letters of the second table, as F,G,Q, and Z, involving the second secret by means of the remaining letters, differently transposed, and then combining the two, as previously instructed.
