This system of coding is applied in a similar manner to the letters of the alphabet, and by this means any word can be easily spelled. But to avoid detection, the letters have to be transposed somewhat after the following fashion, which must only be considered as an example, being too easy of detection for practical use.
| A | becomes | B |
| B | „ | C |
| C | „ | D |
| D | „ | E |
| E | „ | F |
| F | „ | G |
| G | „ | H |
| H | „ | I |
| I | „ | J |
| J | „ | K |
| K | „ | L |
| L | „ | M |
| M | „ | N |
| N | „ | O |
| O | „ | P |
| p | „ | Q |
| Q | „ | R |
| R | „ | S |
| S | „ | T |
| T | „ | U |
| U | „ | V |
| V | „ | W |
| W | „ | A |
| X | „ | “now” |
| Y | „ | “easy” |
| Z | „ | “plain” |
To show how this is used, it may be supposed that the Professor has in his hand a brown cap, which some little boy in the audience has given him.
“Do be quick, if you please, and tell me what I have in my hand?” (d = c, b = a, q = p.)
“A cap,” answers Mlle. C.
“Come, say precisely, if you please, what color?” (c = b, s = r, p = o.)
“It is a brown cap,” answers she.
This system can be simplified yet further by coding the various objects most likely to be required, in a way similar to the following:—
Touch = part of clothing.
Look at = part of the room.
