The eighth edition of this work is now being distributed. The new edition embraces the entire North American continent, and considering the vast territory it covers and the data for so many thousands of practitioners, it is fairly accurate and complete. Many new and valuable features are noted and the publishers seem to have covered the ground so thoroughly that all information to be expected in the field it occupies has been anticipated and fully supplied. The register has grown to be a voluminous publication and it is noted that this edition comprises 3,074 closely printed pages. Its exhaustive data certainly brings the medical men of the land in closer touch than could be the case otherwise. It is a roster of the profession in the northern half of our hemisphere and it is probably the largest professional directory in the world.
