Originally published in ca. 1848. This volume from the Cornell University Library's print collections was scanned on an APT BookScan and converted to JPG 2000 format by Kirtas Technologies. All titles scanned cover to cover and pages may include marks notations and other marginalia present in the original volume.
The oldest book in my cryptobook collection (at time of typing, my 1st edition copy is 165 years old!). Contains simple ciphers with illustrations, all presented in Victorian diction.
