Cryptanalysis of the Simple Substitution Cipher With Word Divisions Using Non-Pattern Word Lists

This text is directed toward solving the difficult ciphers. Chapters are devoted to the problem of separating vowels from consonants. With letters divided into vowels and consonants, a tabular section in the text provides some 60,000 "non-pattern" words where the words are arranged by their vowel-consonant distribution, thereby allowing words to be more easily identified.
