namely the letter P, be transposed.  M is found in the eleventh place: therefore the letter E, which is found in the eleventh place after the letter P, is transposed; and so on.  The complete text is this: Pesfer nsonc bmpcxsfdcgx.

Besides the Modes thus obtained by subdivision, there is still another Mode, quite distinct from these and standing by itself, to which the arrangement in this table applies, but I will explain this in a more convenient place and connection (below, c.22).  so much, then, for the first general class as such.

But this Mode may be varied and still further hidden in two principal ways.  For, first, the words which we, for instance, obtained above by Transposition, Otasln eimcn etc.., may still further transposed as follows: T is the first letter after O: therefore after the letter O, which is retained, the letter E must be transposed.  A is the third letter after T, and therefore the letter C must be written; and so on.  There will thus be made the following arrangement of letters: Oecrob, Odbni, Rbdnbnnsndd.  And so in the same way this combination and arrangement may for the third time be still further transposed, with the result that the following will have to be written: Ontosi mmtls gfbhllxeqnx.  Another Mode whereby the process is varied and the secret further hidden is that wherein, after having transposed the letters, as before, by Simple Transposition, we interchange them according to the arrangement presented in the table under the head of the transferred alphabet.  As an example, the principal example given above will serve:  Otasln etc.  That the process may be made perfectly evident, the text is here transposed for the second time, thus:
