Came to visit and dine with me my Lord Viscount Cornbury and his Lady; Lady Frances Hyde, sister to the Duchess of York; and Mrs. Dorothy Howard, maid of Honor. We went, after dinner, to see the formal and formidable camp on Blackheath, raised to invade Holland; or, as others suspected for another design. Thence, to the Italian glass-house at Greenwich, where glass was blown of finer metal than that of Murano, at Venice.
