TRANSCRIBER'S NOTE
Obvious typographical errors and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources.
For consistency and clarity, the pound abbreviation 'l.' has been italicized, so for example '123,321l.' has been replaced by '123,321l.' in the etext.
For consistency, the date and salutation at the beginning of each letter, and the closing and name at the end of each letter, have been put on separate lines (they were sometimes placed on the same line in the original printed text).
Three or more asterisks, sometimes spaced, were used by the editor to indicate omitted text, and sometimes '— — —' or '——' were used. Missing names were indicated by '——' or by '****'. For this reason thought breaks in the text are indicated by two blank lines, not by a line of asterisks.
A deliberate blank space in the text is indicated by [ ].
All the changes noted in the Errata ([pg vi]) have been applied to the text.
Many Footnotes have the signature 'B. V.' rather than 'Editor'. This is explained in Vol 1 p 399 Footnote [90], and is copied below for the reader's convenience:—
