"WHOSOENER THOU art, into whose hands these researches the art of divining, by the visions of the night shall fortune to fell, KNOW WELLthat they are neither light, vain, nor frivolous, but the wearisome labours and the midnight toils of fall many a seas,, of deep thought, subtle attention, and arduous endeavours into the hidden mysteries of nature, Albeit, thou maayst rest assured that in these tiresome researches and manifold watchings, there would spring up at times goodly refreshment by reason of those subtle troths that I ever and anon made manifest, per adventure otherwise, these writings of mine bad, forsooth, been plunged, ere now, into the dark gulf of oblivion, there to perish as unworthy thy especial notice. But, CERTES they now appear before thee in fair and goodly array, clothed in the garb of truth, Yet, ere thou proceedest to unrol their mystic contents, Rembember thou well, to eschew all evil, vain, and frivolous ooubtings; clothe thyself with fortitude; arm thyself with the goodly harness of sincerity; and learn, also, to adore and reverence thy Almighty Maker! He it is who speaketh to man when deep sleep falleth on his eyes; from his inspiration alone canst thou hope to derive instruction. Nevertheless, by the curious art hereafter laid down, shalt thou be enabled to divine much of the future; and the visions of the night, the phantasms of thy deep slumber, shall so prove to the most
"THEREFORE the dreamer would know the true interpretation of his vision, which troubles his thoughts and disquiets his soul, let him in the first place mark down, with any convenient instrument (as pen, pencil, or any thing capable of making the marks distinct), TEN LINES OF CIPHERS, as shown hereafter, without counting them, so as the number thereof may be (as far as the diviner knows) left to chance-albeit, chance herein has but little to do; but the number of his Ciphers must not be arithmetically counted or known at the time, while the diviner is marking them, but set down as it were at random, no matter how roughly they are made; for therein lays the little secret of this book-that the occult principle of the soul shall so guide or counsel the dreamer (or diviner) and control his hand, that he shall mark down those signs alone which will convey a true answert in the matter of his cogitations. All men have knowledge what wonderful power these Ciphers have allotted them, in increasing and diminishing certain numbers in the art decimal and the art of arithmetic; and be assured, they have equal power when used as vehicles of presaging in Dreams and Visions. - From whence this art has been, by those of old, termed the art of SEPHROMANCY, Pursue, therefore, in full faith and credence, these aforesaid rules, and the foreknowledge of the dream shall be made known to thee."
You can form the lines of Ciphers as if at random, in this manner:

Then, let the dreamer proceed to count the Ciphers in each line of the whole, separately, and mark down the number of each line, whether it be an odd or an even number therein.
The odd numbers are,
1. 3. 6. 7. 9. 11. 13. 16. 17. 19. 21. The even numbers are,
2. 4. 6. 8. 10. 12. 14. 16. 18 20 22.
Going through each line separately, let him count the Ciphers, and if the number of Ciphers in the first line be odd, let him mark down one Cipher as the result; but, if event two: thus proceeding through the first five tines, which will constitute the First Sign, marked in the Columns of Oracles as No. 1.
Then go through the other five lines, in the same manner, and proceed as before, counting the Ciphers in each tine, and marking them down as odd or even. This will give the Second Sign, marked in the Columns of Oracles as No. 2.
Here follows an Example of the whole process:-

Those five lines of Ciphers make thus one Sign.

And the second five lines of Ciphers make the Second Sign.
In the next place, let the dreamer place the two signs together, thus, as in the margin is shown, and refer to the pages of Oracles in the book, looking carefully down the sides thereof for the corresponding Signs, which will be most readily found, and the answer to the Dream will be opposite to the Sign, thus:-
For the foregoing Signs, formed as above, you will find at page 51, the following Oracle, or Interpretation:
" The interpretation of thy Dream is this: That thy fate is about to undergo a powerful change, and friends, as well as a better fortune, await thee."
