Sir, I am extremely obliged to you for the favour of your letter, and the enclosed curious one of Sir William Herbert. It would have made a very valuable addition to Lord Herbert's Life, which is now too late; as I have no hope that Lord Powis will permit any more to be printed. There were indeed so very few, and but half of those for my share, that I have not it in my power to offer you a copy, having disposed of my part. It is really a pity that so singular a curiosity should not be public; but I must not complain, as Lord Powis has been so good as to indulge my request thus far. I am, Sir, Your much obliged humble servant, H. W.
