Minor punctuation errors in the Index have been silently corrected.

The word ‘consciousness’ appears twice as ‘conciousness’ in a letter to Basil Hall Chamberlain (pp. 234, 236). It frequently appears correctly spelled elsewhere. It has been corrected in both places here, assuming a printer’s error. The name ‘BlouËt’ or ‘Blouet’, which both appear only in the index under his pen-name of Max O’Rell, have been left as printed.

Page references in the Index remain as printed. There are two entries (‘Prose, poetical’ and ‘Heine, Heinrich, French prose translation of’) referencing p. 524 of the present volume, which is a blank page. Both seem to be errors for p. 529, where both topics are found. These have been corrected. Other than these instances, no systematic attempt was made to verify the accuracy of the Index.

Language tags have been used for italicised words and phrases only, where it seems a special emphasis is placed on their ‘foreignness.’ There are many instances of non-English words which are not in italic. These were not tagged.
