A Cipher between Cardinal Mazarin and Anne d'Autriche

I added a section "Mazarin-Anne d'Autriche Cipher (1651)" in "Cardinal Mazarin and Ciphers". Although the nomenclature of the cipher is printed in Ravenel (1836), the substitution alphabet is not included therein. I reconstructed the substitution cipher by comparing the manuscript letters and the version printed in Ravenel (1836). (Though Ravenel suggests the manuscript key is extant, I could not find it online.)
