In the preparation of this work the author has endeavored to furnish all the authorities derived from the decisions of the Supreme Court and the various Circuit and District Courts of the United States, as well as of the courts of last resort of the several States, touching the points which have been the subject of controversy since the adoption of the Constitution, and down to the time of publication of this volume. The points decided have been condensed as much as possible, leaving to the reader the opportunity to consult the decisions in which such points have been discussed by references to the authorities consulted. The notes will, it is believed, furnish a full and complete and at the same time a ready index to the points which have been called in question for the last hundred years.
