Pepy's Diary. 25 Jun 1667. So to the office, and there Sir W. Pen (age 46) and I did some business, and then home to dinner, where my wife pleases me mightily with what she can do upon the flageolet, and then I to the office again, and busy all the afternoon, and it is worth noting that the King (age 37) and Council, in their order of the 23rd instant, for unloading three merchant-ships taken up for the King's service for men-of-war, do call the late coming of the Dutch "an invasion". I was told, yesterday, that Mr. Oldenburg (age 48), our Secretary at Gresham College, is put into the Tower [Map], for writing newes to a virtuoso in France, with whom he constantly corresponds in philosophical matters; which makes it very unsafe at this time to write, or almost do any thing. Several captains come to the office yesterday and to-day, complaining that their men come and go when they will, and will not be commanded, though they are paid every night, or may be. Nay, this afternoon comes Harry Russell from Gravesend, Kent [Map], telling us that the money carried down yesterday for the Chest at Chatham had like to have been seized upon yesterday, in the barge there, by seamen, who did beat our watermen: and what men should these be but the boat's crew of Sir Fretcheville Hollis (age 25), who used to brag so much of the goodness and order of his men, and his command over them.

Evelyn's Diary. 08 Aug 1667. Visited Mr. Oldenburg (age 48), a close prisoner in the Tower [Map], being suspected of writing intelligence. I had an order from Lord Arlington (age 49), Secretary of State, which caused me to be admitted. This gentleman was secretary to our Society, and I am confident will prove an innocent person.

Evelyn's Diary. 28 Feb 1676. [Note. Date adjusted to 28 Feb since original entry stated 29 Feb when it isn't a leap year.] I dined with Mr. Povey (age 62), one of the Masters of Requests, a nice contriver of all elegancies, and exceedingly formal. Supped with Sir J. Williamson, where were of our Society Mr. Robert Boyle (age 49), Sir Christopher Wren (age 52), Sir William Petty (age 52), Dr. Holden, subdean of his Majesty's (age 45) Chapel, Sir James Shaen, Dr. Whistler, and our Secretary, Mr. Oldenburg (age 57).
