I was now chosen (and nominated by his Majesty for one of the Council), by suffrage of the rest of the members, a Fellow of the Philosophic Society now meeting at Gresham College, where was an assembly of divers learned gentlemen. This being the first meeting since the King's return; but it had been begun some years before at Oxford, and was continued with interruption here in London during the Rebellion.

There was another rising of the fanatics, in which some were slain.

16th January, 1661. I went to the Philosophic Club, where was examined the Torricellian experiment. I presented my Circle of Mechanical Trades, and had recommended to me the publishing what I had written of Chalcography.

25th January, 1661. After divers years since I had seen any play, I went to see acted "The Scornful Lady," at a new theater in Lincoln's-Inn Fields.

30th January, 1661. Was the first solemn fast and day of humiliation to deplore the sins which had so long provoked God against this afflicted church and people, ordered by Parliament to be annually celebrated to expiate the guilt of the execrable murder of the late King.

This day (Oh, the stupendous and inscrutable judgments of God!) were the carcasses of those arch-rebels, Cromwell, Bradshawe (the judge who condemned his Majesty), and Ireton (son-in-law to the Usurper), dragged out of their superb tombs in Westminster among the Kings, to Tyburn, and hanged on the gallows there from nine in the morning till six at night, and then buried under that fatal and ignominious monument in a deep pit; thousands of people who had seen them in all their pride being spectators. Look back at October 22, 1658,[65] and be astonished! and fear God and honor the King; but meddle not with them who are given to change!

6th February, 1661. To London, to our Society, where I gave notice of the visit of the Danish Ambassador-Extraordinary, and was ordered to return him their acceptance of that honor, and to invite him the next meeting day.

10th February, 1661. Dr. Baldero preached at Ely-house, on Matthew vi. 33, of seeking early the kingdom of God; after sermon, the Bishop (Dr. Wren) gave us the blessing, very pontifically.

13th February, 1661. I conducted the Danish Ambassador to our meeting at Gresham College, where were shown him various experiments in vacuo, and other curiosities.

21st February, 1661. Prince Rupert first showed me how to grave in mezzo tinto.
