10 June 1680 – 16 June 1680

Came to dine with us the Countess of Clarendon, Dr. Lloyd, Dean of Bangor (since Bishop of St. Asaph), Dr. Burnet, author of the "History of the Reformation," and my old friend, Mr. Henshaw. After dinner we all went to see the Observatory, and Mr. Flamsted, who showed us divers rare instruments, especially the great quadrant.
