Dined with me Monsieur Kiviet, a Dutch gentleman-pensioner of Rotterdam, who came over for protection, being of the Prince of Orange's party, now not welcome in Holland. The King knighted him for some merit in the Prince's behalf. He should, if caught, have been beheaded with Monsieur Buat, and was brother-in-law to Van Tromp, the sea-general. With him came Mr. Gabriel Sylvius, and Mr. Williamson, secretary to Lord Arlington; M. Kiviet came to examine whether the soil about the river of Thames would be proper to make clinker bricks, and to treat with me about some accommodation in order to it.

9th January, 1666-67. To the Royal Society, which since the sad conflagration were invited by Mr. Howard to sit at Arundel-House in the Strand, who at my instigation likewise bestowed on the Society that noble library which his grandfather especially, and his ancestors had collected. This gentleman had so little inclination to books, that it was the preservation of them from embezzlement.
