With a View to encouraging students to read as widely as possible, I have placed at the head of each chapter a bibliography of the best literature in English, German, French, and Italian, dealing with the subject treated in the chapter, and have cited many additional authorities in the footnotes. Proofs of various parts of the book have been read by university professors, each of whom is an authority on the particular subject dealt with in the chapter submitted to him, and the entire work has had the benefit of their suggestions. For this service my thanks are due to Professors J. Q. Dealey, of Brown University; W. F. Dodd, of Johns Hopkins University; Blaine F. Moore, of the University of Michigan; Paul S. Reinsch, of the University of Wisconsin; L. S. Rowe, of the University of Pennsylvania; Walter J. Shepard, of the University of Ohio; D. Y. Thomas, of the University of Arkansas; and W. W. Willoughby, of Johns Hopkins University; to my col leagues, Professors John A. Fairlie, David Kinley, and N. A. Weston, and Messrs. F. C. Becker and Thomas Reed Powell, of the Univer sity of Illinois; to Mr. Roy E. Curtis, formerly of the Wisconsin Legislative Reference Bureau; and to Mr. H. G. James, graduate student in the University of Illinois and member of the Illinois bar.
