Obvious punctuation errors corrected. Inconsistent hyphenation is primarily due to the large number of sources of the material, and has been retained as printed. Inconsistent use of double consonants (e.g. downfal, premisses) is common for the period and has been retained. There are numerous places in the printed book where letters or punctuation failed to print, and where the space reserved for them clearly indicates a printing error. These omissions have been restored.
