The "Friend" was Coleridge. In the original MS. it stands "Coleridge! I know not," etc. Wordsworth changed it in the proof stage.—Ed.
Compare—in Hartley Coleridge's Lives of Distinguished Northerners—what is said of this sonnet, in his life of Anne Clifford, where the passing cynicism of Wordsworth's poem is pointed out.—Ed.
Note:
Wordsworth stayed in London from August 30th to September 22nd 1802.—Ed.
