No abstract provided. / Thesis / Master of Arts (MA) / Scope and contents: The first part of the thesis is an orientation to the novel itself, since the entire work must be taken as the only meaningful context for a consideration of the substantive variants. The second part consists of an examination of the selected revisions in the light of the full context and of James's theory of revision. The third part is a record of substantive variants. The appendices contain a report on computer collation of a section of the text and two extended notes on specific substantive variants.
