ADVANCEMENT OP LBAHNlXQ, [fiOOB 



THE FIRST, OB BOMAN ALPHABET. 



All the letters of this Roman alphabet are read or deci 

 Inhered, by translating them into the letter A only. 



THE SECOND, OR ITALIC ALPHABET. 



All the letters of this Italic alphabet are read by trans 

 lating them into the letter B only. 



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

 by letter, to the internal writing, first made biliterate ; and 

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

 Suppose the external writing were, tl Stay till I come to you,&quot; 

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

 word &quot; Fly,&quot; resolved by means of the biliteral alphabet, is 



PLY 

 aabab ababa babba 



whereof I fit, letter by letter, the words &quot; Stay till I come 

 to you,&quot; observing the use of my two alphabets of differently 

 shaped letters, thus : 



aabab ababa babba 

 Stay t Hi co me 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 Roman 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. 1 *
