28 August 1662 – 3 September 1662

The Council and Fellows of the Royal Society went in a body to Whitehall, to acknowledge his Majesty's royal grace in granting our Charter, and vouchsafing to be himself our founder; when the President made an eloquent speech, to which his Majesty gave a gracious reply and we all kissed his hand. Next day we went in like manner with our address to my Lord Chancellor, who had much promoted our patent: he received us with extraordinary favor. In the evening I went to the Queen-Mother's Court, and had much discourse with her.

Being invited by Lord Berkeley, I went to Durdans, where dined his Majesty, the Queen, Duke, Duchess, Prince Rupert, Prince Edward, and abundance of noblemen. I went, after dinner, to visit my brother of Woodcot, my sister having been delivered of a son a little before, but who had now been two days dead.
