The theory of diagnosis by transillumination is no longer considered to be hearsay or heresy by the thinkers in medicine and dentistry. The universal approval accorded the first four editions of "Diagnosis by Transillumination" has prompted the preparation of a fifth edition, revised and amplified into a substantial text-book worthy of a place in the dentist's or physician's library and the college class room. A logical presentation of convincing arguments sufficient to satisfy every open-minded analyst is given herein, and much care has been taken to emphasize the limitations, as well as advantages, of the methods considered. Interested investigators will find many of the ideas presented in this book the result of original research. And, these methods are now being taught in many of the leading dental and medical schools. The methods outlined in this book have been generally accepted by leading physicians and dentists, and the clinical results obtained by the use of transillumination in actual practice are assuredly the best indication of its value. - Preface.
