The following tables will illustrate the making and working—both in ciphering and de-ciphering—of the amended Biliteral Cipher of Francis Bacon:
CIPHER FOR NUMBERS AND DOTS.
| P (Plain) means letter left untouched | D (Dot) means letter with dot in body |
| One Dot—(.) at Top (t) = 2 | Two Dots—(. .) at Top (t) = 4 |
| One Dot— (.) at Bottom (b) = 3 | Two Dots— (. .) at Bottom (b) = 5 |
| Bacon Cipher. | No. of Sym- bols Required |
Number Cipher. | Alphabet to be arranged in order. | Dot Cipher. | |
| No. Values of Symbols reported. | |||||

| Note.—When there are to be two dots at either top or bottom of a letter, the dot usually put in the body of a letter which is to indicate "b" can be placed at the opposite end of the letter to the double dotting. This will help to baffle investigation without puzzling the skilled interpreter. | |||||
