In his _Historical Plays_, whenever our _English_ Chronicles, and in his Tragedies when _Greek_ or _Roman_ Story, could give any Light; no Pains have been omitted to set Passages right by comparing my Author with his Originals; for as I have frequently observed, he was a close and accurate Copier where-ever his _Fable_ was founded on _History_. Where-ever the Author’s Sense is clear and discoverable (tho’, perchance, low and trivial), I have not by any Innovation tamper’d with his Text, out of an Ostentation of endeavouring to make him speak better than the old Copies have done. Where, thro’ all the former Editions, a Passage has labour’d under flat Nonsense and invincible Darkness, if, by the Addition or Alteration of a Letter or two, or a Transposition in the Pointing, I have restored to Him both Sense and Sentiment; such Corrections, I am persuaded, will need no Indulgence. And whenever I have taken a greater Latitude and Liberty in amending, I have constantly endeavour’d to support my Corrections and Conjectures by parallel Passages and Authorities from himself, the surest Means of expounding any Author whatsoever. _Cette voïe d’interpreter un Autheur par lui-même est plus sure que tous les Commentaires_, says a very learned _French_ Critick. As to my _Notes_ (from which the common and learned Readers of our Author, I hope, will derive some Satisfaction), I have endeavour’d to give them a Variety in some Proportion to their Number. Where-ever I have ventur’d at an Emendation, a _Note_ is constantly subjoin’d to justify and assert the Reason of it. Where I only offer a Conjecture, and do not disturb the Text, I fairly set forth my Grounds for such Conjecture, and submit it to Judgment. Some Remarks are spent in explaining Passages, where the Wit or Satire depends on an obscure Point of History: Others, where Allusions are to Divinity, Philosophy, or other Branches of Science. Some are added to shew where there is a Suspicion of our Author having borrow’d from the Ancients: Others, to shew where he is rallying his Contemporaries; or where He himself is rallied by them. And some are necessarily thrown in, to explain an obscure and obsolete _Term_, _Phrase_, or _Idea_. I once intended to have added a complete and copious _Glossary_; but as I have been importun’d, and am prepar’d, to give a correct Edition of our Author’s POEMS (in which many Terms occur that are not to be met with in his _Plays_), I thought a _Glossary_ to all _Shakespeare_’s Works more proper to attend that Volume.
