2 May 1661 – 8 May 1661

I had audience of my Lord Chancellor about my title to Sayes Court.

I went to see the wonderful engine for weaving silk stockings, said to have been the invention of an Oxford scholar forty years since; and I returned by Fromantil's, the famous clockmaker, to see some pendules, Monsieur Zulichem being with us. This evening, I was with my Lord Brouncker, Sir Robert Murray, Sir Patrick Neill, Monsieur Zulichem, and Bull (all of them of our Society, and excellent mathematicians), to show his Majesty, who was present, Saturn's annulus, as some thought, but as Zulichem affirmed with his balteus (as that learned gentleman had published), very near eclipsed by the moon, near the Mons Porphyritis; also, Jupiter and satellites, through his Majesty's great telescope, drawing thirty-five feet; on which were divers discourses.

His Majesty rode in state, with his imperial crown on, and all the peers in their robes, in great pomp to the Parliament now newly chosen (the old one being dissolved); and, that evening, declared in council his intention to marry the Infanta of Portugal.
