We may well exclaim, as we behold this appendage to man,--now of no use in health and of the most doubtful assistance to the very organ it was intended to protect, when that organ, through its iniquitous tastes, has got itself into trouble, and, Job-like, is lying repentant and sick in its many wrappings of lint, with perhaps its companions in crime imprisoned in a suspensory bandage,--what is this prepuce? Whence, why, where, and whither? At times, Nature, as if impatient of the slow march of gradual evolution, and exasperated at this persistent and useless as well as dangerous relic of a far-distant prehistoric age, takes things in her own hands and induces a sloughing to take place, which rids it of its annoyance. In the far-off land of Ur, among the mountainous regions of Kurdistan, something over six thousand years ago, the fathers of the Hebrew race, inspired by a wisdom that could be nothing less than of divine origin, forestalled the process of evolution by establishing the rite of circumcision. Whether this has been beneficial or injurious to the race will be, in a measure, the object of the discussion in this book. One object of this book is to furnish my professional brothers with some embodied facts that they may use in convincing the laity in many cases where they themselves are convinced that circumcision is absolutely necessary; but, having nothing in their text-books to back up their opinion with, their explanations are too apt to pass for their mere unfounded personal view of the matter. If the patient, or the parents of the patient, ask the physician for his authority, he is at a loss, as there is nothing that deals with the subject in any extended manner; so that this book has been written in as plain English as the subject-matter could possibly allow, so that non-professionals could easily read and understand it. I have often felt the need of such a work; people can understand emergency or accident surgery, military surgery, or reparative surgery, but such a thing as surgery to remedy a seemingly medical disease, or what might be called the preventive practice of surgery, is something they cannot understand. First, and not the least, among the incentives to skepticism on this subject is the unwelcome fact of a surgical operation, which, no matter how trivial it may seem to the surgeon, is a matter of considerable magnitude to the patient, his parents, or friends; there are risks, pain, worry, annoyances, and expenses to be undergone,--considerations which, either singly or unitedly, often lead one to reason against the operation, even when otherwise convinced of its need or utility.
