Intestinal Ills

The following chapters were contributions to Health--a monthly magazine published in New York City. Certain peculiarities of form and considerable repetition of statement--both of which the reader cannot fail to notice--are owing to the fact that about two-thirds of the chapters were written under the caption "Auto-genetic Poisons in the Intestinal Canal and their Auto-infection." In revising these contributions for book form I have given to each chapter a caption of its leading thought; but I am convinced that repetition of some of the matters treated, especially if the repetition be in a somewhat different connection, is not such a very bad thing.
