Gray and Collins
Note from 'On the Ignorance of the Learned' by William Hazlitt

Gray, of course, is Thomas Gray. Collins is, I believe, another English poet, William Collins (1721-1759), who, because he was "too indolent" for the army, and dissuaded from going to the church, went off to London to write; there, to fall into "irregular habits." The fame of Collins, such as it is, rests on his Odes, published in 1747.
