Simple typographical errors were silently corrected.

This book contains many unmatched quotation marks. They are not noted here, and with two exceptions noted below, have not been remedied.

Ambiguous hyphens at the ends of lines were retained.

Most illustrations originally were printed just before the beginning of a chapter. In this eBook, the ones that were printed mid-chapter have been moved to just before their chapters.

The illustrations included specimen signatures, which have been used as captions in this eBook.

Most of the illustrations included the names of the engravers. To avoid confusion with the specimen signatures, the engravers' names are given here:

By H. W. Smith, Boston:
John A. Andrew, Henry Ward Beecher, Wm. A. Buckingham, Schuyler Colfax, Wm. Lloyd Garrison, Wendell Phillips, Charles Sumner.

By A. H. Ritchie:
S. P. Chase, Frederick Douglass, D. E. Farragut, Harriet Beecher Stowe, Horace Greeley, O. O. Howard, A. Lincoln, Phil. H. Sheridan, W. T. Sherman, Edwin M. Stanton, N. Wilson.

The illustration of U S Grant did not include an engraver's name.

Text sometimes uses "borne" where modern spelling is "born." It also uses "borne" in the modern sense.

Page [42]: Transcriber added quotation mark in 'parallel is taken, "Mr. Webster added' to match the one following '88."'
