Albert Angus Turbayne Monograms and Ciphers

Annotation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. By limiting the number of combinations containing the I and J, and the O and Q, which can easily be made interchangeable in the working, and giving but a single reading of most of the devices containing the letters X, Y, Z, which will be the least used, I have been able to present a good working selection of two letters and a repeated letter in I 13 plates. Three digerent letters, as I have stated, can be read in six ways. Take, for instance, the first three letters of the alphabet.
