Ever since lawyers first began the practice of employing expert witnesses in cases where there were questions of fact to be determined, involving the existence and extent and the causes of bodily ailments, these experts-physicians, surgeons, anatomists, chemists, pathologists, and roentgenologists-have been generous in their proffering of advice to the practicing attorney as to the matters to which his preparation for trial should be directed, the proper theories to be adopted by him as to recovery or damages and his methods of examining and cross-examining witnesses of this character. The shelves of any large law library will be found to be filled with texts on this subject by learned men of all nationalities and races. A large number of those works would now probably be regarded as obsolete by the members of the profession; but, in the past twelve years, in this country there have been published at least seven more or less exhaustive treatises on the whole or on various parts of this general subject.
