The same deciphered by means of the table and key:—
“Français! votre pays étoit trahi; votre Empereur seul peut vous remettre dans la position splendide que convient à la France. Donnez toute votre confiance à celui qui vous a toujours conduit a la gloire. Ses aigles pleniront encore en l’air et étonneront les nations.”
Frenchmen! your country was betrayed; your Emperor alone can replace you in the splendid state suitable to France. Give your entire confidence to him who has always led you to glory. His eagles will again soar on high and strike the nations with astonishment.
The key (which, it will be seen, may be changed at pleasure) was in this instance “La France et ma famille,” France and my family. It is thus used:—
L being the first letter of the key, refer to that letter in the first column of the cypher in capitals; then look for the letter f, which is the first letter of the proclamation, and that letter which corresponds with f being placed underneath, viz., n, is that which is to be noted down. To decipher the proclamation, of course the order of reference must be inverted, by looking for the corresponding letter to n in the division opposite that letter L which stands in the column.
