Leaving the university without a degree, he settled in chambers in the Inner Temple, moving later to a house on Hampstead Heath, where he collected a valuable library, rich in Elizabethan literature.
He made changes in the text sometimes apparently with the sole object of showing how much abler he was as an emendator than Malone, but his wide knowledge of Elizabethan literature stood him in good stead, and subsequent editors have gone to his pages for parallel passages from contemporary authors.
His deficiencies from the point of view of purely literary criticism are apparent from the fact that he excluded Shakespeare's sonnets and poems because, he wrote, "the strongest act of parliament that could be framed would fail to compel readers into their service.
He wrote an entirely fictitious account of the Java upas tree, derived from an imaginary Dutch traveller, which imposed on Erasmus Darwin, and he hoaxed the Society of Antiquaries with the tombstone of Hardicanute, supposed to have been dug up in Kennington, but really engraved with an Anglo-Saxon inscription of his own invention.
A monument to his memory by John Flaxman, with an inscription commemorating his Shakespearian labours, was erected in Poplar Chapel.
