From the above outline it will be easier for the reader to follow out the reasons, or the whys or wherefores, of the views expressed on medicine in the course of the book; and, although I do not wish to enter the medical field like a Peter the Hermit on a new crusade, to lure thousands into the hands of the circumcisers, nor, as a new Mohammed, promise the eternal bliss and glory of the seventh heaven to all the circumcised, I ask of my professional brothers a calm and unprejudiced perusal of the tangible and authentic facts that I have honestly gathered and conscientiously commented upon from my field of vision, which will be plainly presented in the following pages. I simply have given the facts and my impressions: the reader is at liberty to draw his own conclusions. If I have been too tedious in the multiplication of incidents in support of certain views, I must remind the reader that the verdict goes to him who has the preponderance of testimony, and that many a lawsuit is lost from the neglect, on the part of the loser, to secure all the available testimony. Having brought the subject of circumcision before the bar of public opinion, as well as that of my professional brother, I would but illy do justice to the subject at the bar, or to myself, not to properly present the case; as it was remarked by Napoleon, "God is on the side of the heaviest artillery," and he who loses a battle for want of guns should not rail at Providence if, having them on hand, he has neglected to bring them into action. The reasons for the existence of the book will become self-evident as the reader labors through the medical part of the work. Our text-books are, as a class, even those on diseases of children as a specialty, singularly and unpardonably silent and deficient on the subject of either the prepuce and the diseases to which it leads, or circumcision; and even our surgical works are not sufficiently explicit, as they deal more with the developed disease and the operative measures for its removal than on any preventive surgery or medicine. Our works on medicine are equally silent, and, although from a perusal of the latter part of the book the prepuce and circumcision will be seen to have considerable bearing on the production and nature of phthisis, this subject would, owing to our strabismic way of studying medicine, look most singularly out of place in a work devoted to diseases of the lungs or throat. Owing to this poverty of literature on the subject, and that the library of the average practitioner could therefore not furnish all the data relating to it that the profession have in their possession, a book of this nature will furnish them the required material whereupon to form the basis of an opinion on the subject.
