15th October, 1677. Returned to London; in the evening, I saw the Prince of Orange, and supped with Lord Ossory.

23d October, 1677. Saw again the Prince of Orange; his marriage with the Lady Mary, eldest daughter to the Duke of York, by Mrs. Hyde, the late Duchess, was now declared.

11th November, 1677. I was all this week composing matters between old Mrs. Howard and Sir Gabriel Sylvius, upon his long and earnest addresses to Mrs. Anne, her second daughter, maid of honor to the

Queen. My friend, Mrs. Godolphin (who exceedingly loved the young lady) was most industrious in it, out of pity to the languishing knight; so as though there were great differences in their years, it was at last effected, and they were married the 13th, in Henry VII.'s Chapel, by the Bishop of Rochester, there being besides my wife and Mrs. Graham, her sister, Mrs. Godolphin, and very few more. We dined at the old lady's, and supped at Mr. Graham's at St. James's.

15th November, 1677. The Queen's birthday, a great ball at Court, where the Prince of Orange and his new Princess danced.

19th November, 1677. They went away, and I saw embarked my Lady Sylvius, who went into Holland with her husband, made Hoffmaester to the Prince, a considerable employment. We parted with great sorrow, for the great respect and honor I bore her, a most pious and virtuous lady.

27th November, 1677. Dined at the Lord Treasurer's with Prince Rupert, Viscount Falkenburg, Earl of Bath, Lord O'Brien, Sir John Lowther, Sir Christopher Wren, Dr. Grew, and other learned men.

30th November, 1677. Sir Joseph Williamson, Principal Secretary of State, was chosen President of the Royal Society, after my Lord Viscount

Brouncker had possessed the chair now sixteen years successively, and therefore now thought fit to CHANGE, that prescription might not prejudice.

4th December, 1677. Being the first day of his taking the chair, he gave us a magnificent supper.
