With each letter classified as to its a or its 17 form, the procedure of deciphering was a simple step forward. Under each letter of the original text was written the a or the b designating the form to which it belonged, and the whole was then divided ofi’ into groups of five, each such group of a’s and 19’s representing one letter as shown in Bacon’s cipher key (see page Facing this page is a transcription of the Prologue arranged in groups of five; beneath each letter is the a or the b, to which form such letter belongs. Each such combination or group will be found to represent a corresponding letter in the cipher key. This is shown in order to enable the reader to follow the method of deciphering — simple enough when the difficult preliminary step already described of assigning the letters to their respective class has been accomplished.
