THE FIRST, OE ROMAN ALPHABET. 



All the letters of this Koman alphabet are read or deci- 

 [ihered, by translating them into the letter A only. 



All the letters of this Italic alphabet are read by trans 

 iating them into the letter B only. 



Now adjust or fit any external double-faced writing, letter 

 by letter, to the internal ^vriting, first made biliterate j and 

 afterwards write it down for the letter or epistle to be sent. 

 Suppose the external writing were, " Stay till I come to you," 

 and the internal one were, " Fly;" then, as we saw above, the 

 word " Fly," resolved by means of the biliteral alphabet, is 



PLY 

 aabab ababa babba 



whereof I fit, letter by letter, the words " Stay till I come 

 to you," observing the use of my two alphabets of differently 

 shaped letters, thus : 



aabab ababa babba 

 Stay t in CO we to you. 



Having now adjusted my writing according to all my alpha- 

 bets, I send it to my correspondent, who reads the secret 

 meaning by translating the Eoman letters into a's, and the 

 Italic ones into 6's, according to the Roman and Italic alpha- 

 bets, and comparing each combination of five of them with 

 the biliteral alphabet.^
