Hyphenation in inconsistent throughout; missing punctuation and occasional missing spaces have been added. The errata have been incorporated. The spelling of character names has been harmonised. Overall, contemporary spellings have been retained; however, a small number of words have been modernised to prevent misunderstanding. One instance of "genus" was left unchanged, since it may well serve a purpose in furthering the characterisation. A section of publisher's advertising at the end was illegible and has been omitted. One instance of double typesetting (same word at end of one line and the beginning of the next) was corrected. Although there is occasional reference in the stage directions to "(the) Miss Ogles" it is clear from the context that the name is "Ogle" and only one character of that name is present, so the name was changed accordingly. At the end of the scene at Sir George's in Act 2, Mrs Racket exits twice in short order; this reflects the original. Three substantive changes were made: In Act 2, "your" was changed to "you" in Harcourt's speech: _Har._ I foresee this won't do!--Mr. Doricourt, may be you take my Daughter for a Fool; but *you* are mistaken: she's a sensible Girl, as any in England. In Act 4, "On" was replaced by "Oh" at the beginning of Flutter's speech: _Flut._ Oh, every creature.--A Mask is nothing at all to me.--I can give you the history of half the people here. In Act 5, scene 3, Is is was changed to Is it in Lady Frances Touchwood's question: Is it true that Doricourt is mad?
