3 March 1664 – 9 March 1664

Came to dine with me the Earl of Lauderdale, his Majesty's great favorite, and Secretary of Scotland; the Earl of Teviot; my Lord Viscount Brouncker, President of the Royal Society; Dr. Wilkins, Dean of Ripon; Sir Robert Murray, and Mr. Hooke, Curator to the Society. This spring I planted the Home field and West field about Sayes Court with elms, being the same year that the elms were planted by his Majesty in Greenwich Park.

I went to the Tower, to sit in commission about regulating the Mint; and now it was that the fine new-milled coin, both of white money and guineas, was established.
