Breakfasted with Mr. Pitt at his country house Near Putny common, Sir Home Popham only present Lord Melville expected but did not arrive, after my being Introduced Mr. Pitt demanded of Sir Home if he and Mr. Francis had agree’d on terms Sir Home replied in the affirmative and told Mr. Pitt his perusal and Signature were only wanting. He then read and Signed the papers, delivering them to Sir Home, with orders to call on Lord Melville for his signature.
