21 August 1662 – 27 August 1662

I was admitted and then sworn one of the Council of the Royal Society, being nominated in his Majesty's original grant to be of this Council for the regulation of the Society, and making laws and statutes conducible to its establishment and progress, for which we now set apart every Wednesday morning till they were all finished. Lord Viscount Brouncker (that excellent mathematician) was also by his Majesty, our founder, nominated our first President. The King gave us the arms of England to be borne in a canton in our arms, and sent us a mace of silver gilt, of the same fashion and size as those carried before his Majesty, to be borne before our president on meeting days. It was brought by Sir Gilbert Talbot, master of his Majesty's jewel house.

I dined with my Lord Brouncker and Sir Robert Murray, and then went to consult about a newly modeled ship at Lambeth, the intention being to reduce that art to as certain a method as any other part of architecture.

I was spectator of the most magnificent triumph that ever floated on the Thames, considering the innumerable boats and vessels, dressed and adorned with all imaginable pomp, but, above all, the thrones, arches, pageants, and other representations, stately barges of the Lord Mayor and companies, with various inventions, music, and peals of ordnance both from the vessels and the shore, going to meet and conduct the new Queen from Hampton Court to Whitehall, at the first time of her coming to town. In my opinion, it far exceeded all the Venetian Bucentoras, etc., on the Ascension, when they go to espouse the Adriatic. His Majesty and the Queen came in an antique-shaped open vessel, covered with a state, or canopy, of cloth of gold, made in form of a cupola, supported with high Corinthian pillars, wreathed with flowers, festoons and garlands. I was in our newly built vessel, sailing among them.
