The written record gives us an admittedly patchy picture of Lodwick's involvement with the Royal Society, and only a slightly fuller one of his philosophical activities. For the most part he was silent at Royal Society meetings, although he attended them regularly. He only contributed one article to the Philosophical Transactions, and his other printed works were published anonymously before his election as a Fellow. There are scattered mentions of him in the Society's financial records and a few of his papers and letters are now in their archives, but most of these are unattributed. His most serious intellectual involvement was probably as a close friend of Hooke and a member of Hooke's philosophical circle—but we can only speculate on these kinds of activities, and rely on scattered evidence from Hooke's diary and the correspondence of Aubrey and others (14).
