ble provided only the objects are but capable of two differ- 

 ences, as bells, speaking-trumpets, fireworks, cannon, etc. But 

 for writing, let the included letter be resolved into this biliteral 

 alphabet ; suppose that letter were the word fly, it is thus re- 

 solved : 



F 



aabab 



L 



ababa 



babba 



Let there be also at hand two other common alphabets, dif- 

 fering only from each other in the make of their letters ; so that, 

 as well the capital as the small be differently shaped or cut at 

 everyone's discretion ; as thus, for example, in roman and 

 italic ; each roman letter constantly representing A, and each 

 italic letter, B. 



THE FIRST, OR ROMAN ALPHABET 



All the letters of this roman alphabet are read or deciphered, 

 by translating them into the letter A only. 



THE SECOND, OR ITALIC ALPHABET 



A, a H t 



B, b 



C, c K, 

 D t d 



E.

 G, g 



All the letters of this italic alphabet are read by translating 

 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. Sup- 

 pose 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
