E-text prepared by an anonymous volunteer

Transcriber's note:

The chapter summaries in the Table of Contents are repeated
in the text at the start of each chapter.

Footnotes are at the end of the chapter (or section of a Table
of Congress), referenced by parenthesized numbers, e.g. (1).

The capitalization of hyphenated words is inconsistent,
following the text, as is the use of the comma in lists.

The tables of the 39th and 40th Congresses are moved to the
Appendices.

Line 2874: "gauge of battle" changed to "gage of battle"

Line 12981: missing numerator in "3/10" supplied from preceding text.

Non-standard spellings: domicil; hinderance; cotemporary]
