Another edition being called for, it appeared evident that several changes were desirable, in order to bring the book in line with rapidly increasing medical knowledge, and to give full effect to more recent experiences in the application of Dr. Kirk's treatment. Since the "Papers" were first written, medical, and especially surgical, practice has very greatly changed, and some of the practices against which Dr. Kirk most vehemently protested have passed away. Hence, certain modifications introduced into this edition, for which the editor accepts full responsibility. For those who wish to consult the actual writings of Dr. Kirk, the original eleven volume edition is still available. Great advances have also been made in the knowledge of the causes of disease; and preventive methods of treatment by regulation of diet and habits of life are much better understood. To incorporate some reference to these in a work dealing with health generally, appeared to us absolutely necessary. For these additions also the writer accepts responsibility. Where it appeared to be useful, illustrations have been introduced, which may help those to whom the treatment is quite new, to practice it more easily and correctly, and to understand better the theories on which it is founded. These changes have enlarged the book, and somewhat increased the price, which is, however, still such as to place the volume within the reach of all classes. It is most gratifying to know through letters received from almost all parts of the world, that many are benefitted very greatly by the treatments described. We have constant evidence coming before us from our own experience with patients of the powerful effect they have in healing the sick, and even saving life. We send out this new edition in the hope that it may spread still more widely, the knowledge of such simple and yet effective means of cure. _EDWARD BRUCE KIRK_ E. U. Manse, Barrhead, Scotland. _July, 1904._ INTRODUCTION. In this book we set forth a series of simple remedies and preventives of many common troubles. They are all well tried and have been proved by long experience to be effective and safe. We give, as far as we know, the reasons why they are likely to do good, but we acknowledge that there are things which we cannot fully explain. For instance, we do not know why a well aired lather of M'Clinton's Soap should have the soothing effect it undoubtedly possesses, or why spreading handfuls of this lather over the stomach of a person suffering from retching or indigestion should give such relief, we only know that it does!
