Four unpublished letters to Newton on alchemy

[Paul Ferguson]

This article analyses four unpublished draft letters from Nicolas Fatio de Duiller to Isaac Newton, dating from June to August 1693, and held in the Special Collections in the Universiteitsbibliotheek in Leiden. Overall, these letters enrich our knowledge of Fatio-Newton’s alchemical correspondence in June 1693, a phase which likely represents the peak of the two natural philosophers’ alchemical collaboration."
