TO MY WIFE WHOSE ENTHUSIASM, AND UNFLAGGING INTEREST IN ALL MATTERS PERTAINING TO HEALTH IS EXCELLED BY NONE, AND WHO HAS BEEN A FAITHFUL CO-WORKER IN BUILDING UP THE SYSTEM OF TREATING DISEASE BY HYGIENIC METHODS HEREIN SET FORTH, THIS BOOK IS AFFECTIONATELY DEDICATED.

The illustration here given of the Digestive Apparatus of man represents the organs of food digestion, especially the alimentary canal and glands connected therewith, and to the reader of this book, or to any student of anatomy, it will be found of invaluable service as a reference.

The diagram gives a view of the digestive organs from the ventral or front side, a proper study of which cannot fail to impress every intelligent being with the reverential deduction of the Psalmist that we are “ fearfully and wonderfully made .”
In presenting to the public the one hundred and seventieth edition of this work, it is a matter for profound gratification to be able to state that the treatment described in its pages has steadily increased in public favor since its introduction. Tens of thousands of grateful people testify to its efficiency, not only as a remedial process, but better still, as a preventive of disease. Truth must ever prevail, and this treatment being based on natural law (which is unerring), must achieve the desired result, which is the restoration and preservation of health.
