John William Cousin, A Short Biographical Dictionary of English Literature… (1910)
“ Leaving the Univ. he came to London and maintained himself by conducting and writing for periodicals. His Poems on Several Occasions, which contained "The Hop Garden," was issued in 1752, and The Hilliad in 1753 against "Sir" John Hill, a notoriety of the day who had attacked him. His mind ultimately gave way, and it was in confinement that he produced by far his most remarkable work, the Song to David, a most original and powerful poem. ”
