Cheney asks Gibson if he would undertake a commission to produce a monument to the wife of
Sir Charles Knightley. Knightley and his son were great friends of the writer, and wanted a design similar to that of his mother [
Harriet Cheney.] They proposed £300, but did not impose a strict limit on the expense.
The letter bears a endorsement by Gibson detailing his charges for three figures and two angels (£370), or two figures only (£280.)
