The author wishes here, also, to express gratitude to many who have not figured by name in the "A.B.-Z.," or elsewhere herein, but whose assistance, encouragement, criticism, and example have helped the cause along in one way or another. Of these many friends a few are quickly recalled, but not necessarily in the order of their friendly service. To John H. Patterson, Esquire, of Dayton, Ohio; Col. James F. O'Shaughnessy, of New York; Stewart Chisholm, Esquire, of Cleveland, Ohio; Fred E. Wadsworth, Esquire, of Detroit, Michigan; and Henry C. Butcher, Esquire, of Philadelphia, are due much for encouragement in pursuing the investigation at critical moments of the struggle; as well as to Hon. William J. Van Patten, of Burlington, Vermont, whose interest in the "A.B.C. Series" began with "Menticulture" and has continued unabated. In Dr. Swan M. Burnett, of Washington, D. C., has been enjoyed a mentor with great scientific discrimination and a sympathy in the refinements of art and sentiment, as expressed in Japanese æsthetic civilisation, which has been extremely encouraging and most inspiring in relation to the whole A.B.C. idea. From Gervais Kerr, Esquire, of Venice, came one of the important suggestions incorporated in the A.B.-Z. Primer; and the young Venetian artist, E. C. Leon Boehm, rendered great service in studying habits of dietetics among the peoples of the Balkan Peninsular, in Turkey, along the Dalmatian Coast, and in Croatia. Prof. William James, of Harvard University, in his Gifford Lectures at the University of Edinburg, Scotland, published under the title of "The Varieties of Religious Experience," gave the practical reformatory effort of the "A.B.C. Series" a great impetus by quoting approvingly from "Menticulture" and "Happiness." Coming from a teacher of philosophy and psychology, with a physiological training and an M.D. degree to support the approval, recognition is much appreciated; but, in addition to his published utterances, Dr. James has followed the psycho-physiological studies of the movement with interest, and has given much valued encouragement.
