“See Cook [op.cit.] for a discussion of Huygens’s unusual wartime visit to Cambridge and the Royal Society. His philosophical contretemps with Isaac Newton in 1675 (referenced in Society minutes as “The Great Corpuscular Debate”) would mark the last significant intellectual discourse between England and the continent prior to the chaos of the Interregnum and the Annexation . . . Some Newton biographers [Winchester (1867), &c] indicate Huygens may have used his sojourn in Cambridge to access Newton’s alchemical journals and that key insights derived thusly may have been instrumental to Huygens’s monumental breakthrough. However, cf. Hooft [1909] and references therein for a critique of the forensic alchemy underlying this assertion.
