BAC: British Art Center copy is possibly the dedication copy to Charles II.
Morland here declares his system to be peculiarly simple to operate, yet to be proof against decipherment by anyone not possessing the key. He complicates his method by the introduction of "nulls." On pages 11-12, he describes a revolving crypto-machine, apparently of his invention. A key to the diagrams on page 12 is headed "Scriptio Cryptographia." It has been cancelled by pasting over it a different key headed "Scriptio Sterganographia."
