His Majesty was pleased to grant me a lease of a slip of ground out of Brick Close, to enlarge my fore-court, for which I now gave him thanks; then, entering into other discourse, he talked to me of a new varnish for ships, instead of pitch, and of the gilding with which his new yacht was beautified. I showed his Majesty the perpetual motion sent to me by Dr. Stokes, from Cologne; and then came in Monsieur Colbert, the French Ambassador.
