An epigraph from "Paradise Lost", taken from the second of the two quotations from that work in the American edition, appears on the title page of each of the three British volumes. Melville's involvement with this rearrangement is not clear: if it was Bentley's gesture toward accommodating Melville, as Tanselle suggests, its selection put an emphasis on the quotation Melville might not have agreed with. The largest of Melville's revisions is the addition to the British edition of a 139-word footnote in Chapter 87 explaining the word "gally". The edition also contains six short phrases and some 60 single words lacking in the American edition. In addition, about 35 changes produce genuine improvements, as opposed to mere corrections: "Melville may not have made every one of the changes in this category, but it seems certain that he was responsible for the great majority of them." The British publisher hired one or more revisers who were, in the evaluation of scholar Steven Olsen-Smith, responsible for "unauthorized changes ranging from typographical errors and omissions to acts of outright censorship". According to biographer Robertson-Lorant, the result was that the British edition was "badly mutilated". The expurgations fall into four categories, ranked according to the apparent priorities of the censor: These expurgations also meant that any corrections or revisions Melville had marked upon these passages are now lost. The final difference in the material not already plated is that the "Epilogue", thus Ishmael's miraculous survival, is omitted from the British edition. Obviously, the epilogue was not an afterthought supplied too late for the edition, for it is referred to in "The Castaway": "in the sequel of the narrative, it will then be seen what like abandonment befell myself." Why the "Epilogue" is missing is unknown. Since nothing objectionable was in it, most likely it was somehow lost by Bentley's printer when the "Etymology" and "Extracts" were moved. After the sheets had been sent, Melville changed the title. Probably late in September, Allan sent Bentley two pages of proof with a letter of which only a draft survives which informed him that Melville "has determined upon a new title & dedication—Enclosed you have proof of both—It is thought here that the new title will be a better "selling" title". After expressing his hope that Bentley would receive this change in time, Allan said that "Moby-Dick is a legitimate title for the book, being the name given to a particular whale who if I may so express myself is the hero of the volume".
