'My press is revived, and is printing a French play written by the old President Hénault. It was damned many years ago at Paris, and yet I think is better than some that have succeeded, and much better than any of our modern tragedies. I print it to please the old man, as he was exceedingly kind to me at Paris; but I doubt whether he will live till it is finished. He is to have a hundred copies, and there are to be but an hundred more, of which you shall have one' (Letter to Montagu, 15 April, 1768). President Hénault died November, 1770, aged eighty-six.
