Came Sir John Duncomb and Mr. Thomas Chicheley, both Privy Councillors and Commissioners of His Majesty's Ordnance, to visit me, and let me know that his Majesty had in Council, nominated me to be one of the Commissioners for regulating the farming and making of saltpetre through the whole kingdom, and that we were to sit in the Tower the next day. When they were gone, came to see me Sir John Cotton, heir to the famous antiquary, Sir Robert Cotton: a pretended great Grecian, but had by no means the parts, or genius of his grandfather.
