PREFACE

TO THE ONE HUNDREDTH EDITION.

In presenting to the public the one hundredth 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.

This edition has been completely revised and much of it rewritten,
and, while the essential principles remain unchanged, some slight
departures from previously expressed opinions may be noted; for in the
years that have elapsed since the first edition saw the light, some
notable advances have been made in rational therapeutics and
dietetics, and no one can afford to lag behind the car of Progress.

The arrangement of the book has been still farther altered, by adding
another part, making nine in all, each part being devoted to a special
phase of the general subject, thus simplifying it, and making its
principles easier of application. Quotations have been freely made
from articles written during the past three years by the author, in
his capacity as editor of "Health," and several new formulas for the
treatment of important diseases have been added to those that have
appeared in previous editions.
