Sir William Petty
About 1665 he presented to the Royal Society, a discourse of his (in manuscript of about quire of paper) of building of ships, which the Lord Brounker (then president) took away, and still keeps saying, it was too great an Arcanum of state to be commonly perused, but Sir William told me that Dr. Robert Wood, M. D. has a copy of it, which he himself has not.
