The letters written along the circumference constitute the Particular Transpositive alphabet.  In the middle of this spider’s web is to be fixed a wing, or  movable index, ( for the letters of this alphabet are not written in alphabetical order), shall correspond thereto.  Let the point, or apex of the index indicate the letter of the circumference which constitutes the second Transpositive letter.  If, now, being instructed in these matters, you address yourself to the act of writing, set down first the letter of the wing, and then join immediately thereto the other letter, that, namely, of the circumference, and in this way you will easily write out the secret in full.
