In this edition, the author has rearranged his material and added some new discussions of value. The book will be found exceedingly practical even to those who seldom attempt to prepare manuscripts evaluating scientific evidence. A proper knowledge of statistics is an exceedingly valuable aid in diagnosis; an understanding of the simple points set forth by Professor Pearl in an entertaining manner would prevent the reception by editors of many articles which seem to their authors to present facts of practical importance, whereas they merely present a coincidence that might have been expected. Some of the chapters of the book are understandable only by physicians who are well grounded in mathematics, but at least five of the chapters may be read to practical advantage by every intelligent reader.
