Warburton[10] was, in his turn, severely criticised by Dr Zachary Grey, and Mr John Upton, in 1746, and still more severely by Mr Thomas Edwards, in his _Supplement to Mr Warburton's edition of Shakespeare_, 1747. The third edition of Mr Edwards's book, 1750, was called _Canons of Criticism and Glossary, being a Supplement, &c._ This title is a sarcastic allusion to two passages in Warburton's preface: 'I once intended to have given the Reader a _body of Canons_, for literal Criticism, drawn out in form,' &c. p. xiv, and 'I had it once, indeed, in my design, to give a general alphabetic _Glossary_ of these terms,' &c. p. xvi. Dr Grey's attack was reprinted, with additions, and a new title, in 1751, and again in 1752. Warburton and his predecessors were passed in review also by Mr Benjamin Heath, in _A Revisal of Shakespeare's text_, 1765. Dr Samuel Johnson first issued proposals for a new edition of Shakespeare in 1745, but met with no encouragement. He resumed the scheme in 1756, and issued a new set of Proposals (reprinted in Malone's preface), 'in which,' says Boswell, 'he shewed that he perfectly well knew what a variety of research such an undertaking required, but his indolence prevented him from pursuing it with that diligence, which alone can collect those scattered facts that genius, however acute, penetrating, and luminous, cannot discover by its own force.' Johnson deceived himself so far, as to the work to be done and his own energy in doing it, that he promised the publication of the whole before the end of the following year. Yet, though some volumes were printed as early as 1758 (Boswell, Vol. II. p. 84), it was not published till 1765, and might never have been published at all, but for Churchill's stinging satire: 'He for subscribers baits his hook, And takes your cash, but where's the book? No matter where; wise fear, you know, Forbids the robbing of a foe, But what, to serve our private ends, Forbids the cheating of our friends?'
