code-numbers in numerical order stood opposite the alphabetized plaintext elements, but the blocks themselves were in mixed order. A skeleton code, made up from a few groups from Bernstorff's encoding, will illustrate this: encoding decoding 13605 Februar 5144 wenigen 13732 fest 5161 werden 13850 fmanzielle 5275 Anregung 13918 folgender 5376 Anwendung 17142 Frieden 5454 ar 17149 Friedenschluss 5569 auf 17166 fuhrung 5905 Krieg 17214 Ganz geheim 17388 Gebeit 4377 geheim 4458 Gemeinsame The solution of such a hybrid code stands midway in difficulty between the two pure types: harder than a one-part code but easier than a two-part. The large orderly segments considerably help the cryptanalyst, though his guesses are not as delimited as in a one-part code. For example, the cryptanalyst could not assume, as he could in a
