⁴ He wrote (on 6 July 1654): “I have more than once thought of replying to your Latin letters in English, to give you every possible opportunity of writing as well as of speaking English, as I have no doubt you can with equal accuracy. You have indeed learnt to speak our language more accurately and fluently than any other foreigner I have ever known.”

¹⁰ Hooke, 's “Answer to some Particular Claims of M. Cassini's, in his Original and Progress of Astronomy” was first published in Philosophical Experiments (London, 1726), ed. by Derham, W.Google Scholar; the relevant extract was published in Weld, C. R., A History of the Royal Society (London, 1848), i, 37–38.Google Scholar It must be emphasized that Hooke was not associated with the Royal Society until the time of the first charter (1662), whereas Oldenburg was a member from the very beginning of 1661, having been on the list of possible members drawn up 28 November 1660.

¹⁷ The documents are printed in Correspondence, iiiGoogle Scholar; see also McKie, Douglas, “The Arrest and Imprisonment of Henry Oldenburg”, Notes and Records of the Royal Society, vi (1948), 28–47.CrossRefGoogle Scholar Oldenburg believed that the cause of his arrest was his criticism of the incompetent conduct of the Anglo-Dutch War which resulted in the disasters of the Dutch raids of June 1667; it is highly probable that both his arrest and release were the sole responsibility of Lord Arlington, Secretary of State.

²⁶ These volumes were edited by Grew. When they lapsed in 1678 the Society persuaded Hooke to publish what he insisted upon calling Philosophical Collections (1679–82). These were published irregularly, and Phil. Trans., (edited by Robert Plot) was again published at the Society's request in 1683, lapsing only during the troubles of 1688–90; it was once again revived at the insistence of the Society, though it did not officially become the Society's journal until 1750.

²⁷ British Museum Add. MS. 441, f.27. Weld, followed by others, gave this the date 1663, but it must date from a later period—perhaps 1668 or 1669; for before this time the number of correspondents was never so large as this.
