As to Mason, he was certainly a poet; but a malignant man, and particularly malignant against the good King George III. all which malignity was occasioned by some real or imagined slight shown by the King towards his imaginary merit. With all his powers, Mason was a despicable man morally; and that is the worst that need be said of a man.
[Polwhele's note:] Jackson, (who died Bishop of Oxford) had not less an antipathy against Mason. At one of his supper parties, Mason happened to be mentioned, when Jackson spoke of him scornfully. I could scarcely suppress my indignation. Greville's report of Mason (in accordance with Kempethorne's) I am sure comes nearer the truth.
