By and by comes Mr. Cooper, mate of the Royall Charles, of whom I intend to learn mathematiques, and do begin with him to-day, he being a very able man, and no great matter, I suppose, will content him. After an hour’s being with him at arithmetique (my first attempt being to learn the multiplication-table); then we parted till to-morrow.
