| Next, by the process described at p. 53, we transfer to a biliteral Diagram all the information we can. |
| He can then read off, from the biliteral Diagram, the required Propositions. |
| The arrangement of the books was but another variant of our biliteral cipher. |
| The resulting biliteral cipher was then written into a rectangular array and route encrypted by reading the columns in the order indicated by a key word, as illustrated in the figure. |
| Of the quintuple biliteral there are thirty-two combinations. |
| Do you really think from what you have studied that the cipher is a biliteral one, or on the basis of a biliteral cipher? |
