The lasting results and influences are of course problematical. They depend upon the character and soundness of the addresses, and whether the uniform strength of the publication will make the work as a whole, what it undoubtedly is in parts, a source-book for the future on the bases of scientific theory at the beginning of the twentieth century, and a reliable sketch of the growth of science during the nineteenth century. Critical study of the addresses will alone determine this, but from the favorable reception of those already published in reviews, and from editorial acquaintance with the others, it seems assured. That portion of the section addresses which deals with the inter-relations of science and demonstrates both its unity and variety of processes is new and authoritative thought, and will be the basis of much discussion and remodeling of theories in the future. The immediate results of the Congress are highly satisfactory, and fully repay the work and the cost both from a scientific and an exposition standpoint. As an acknowledgment of the prominence of scientific methods, as a public recognition of the work of scientists, as the means of bringing to one place the most noted assemblage of thinkers the world has ever seen, as an opportunity for scholars to meet and know each other better, the Congress was an unqualified success and of enduring reputation. From the Exposition point of view, it was equally a success; not financially, nor was there ever a thought that it would be. Probably not more than seven thousand persons outside of St. Louis came primarily to attend the Congress, and their admission fees were a bagatelle; the revenue derived from the sale of the _Proceedings_ will not meet the cost of printing. There has been no money value sought for in the Congress,--none received. Its value to the Exposition lies solely in the fact that it is the final argument to the world of the initial claims of the officials of the Exposition that its purpose was purely educational. Coördinate with the material exhibits, sought, classified, and installed on a rigidly scientific classification, the Congress, which relates, illumines, and defends the principles upon which the material portion was founded, has triumphantly vindicated the good faith, the wisdom, and the foresight of the Universal Exposition of 1904. This printed record of its proceedings will be a monument not only to the spirit of Science, but to the spirit of the Exposition, which will endure as long as the records of man are preserved. * * * * *
