Two More French Ciphers from Henry IV's Time

I added Salignac's Cipher and Lisle's Cipher in "French Ciphers during the Reign of Henry IV of France".
They are similar to other ciphers at the time, but the 1607 specimen of Lisle's cipher uses two-digit figures not used in the 1606 specimens. It is wondered whether the figure symbols were added, or Lisle simply didn't use figures in 1606.
