Two French Ciphers (ca.1643) in English Archives

French ciphers are sometimes found in English (and probably other) archives. I wrote about the Prince of Conde's cipher and one other the other day. Now, I added mention of two French ciphers (M. de Boisivon, Prince Harcourt) in "Ciphers Early in the Reign of Louis XIV". Although these were shared with English royalists, they are similar to contemporary French ciphers.
