Printed with an English translation in Dobbs, Foundations, 251-5. This was long regarded by Dobbs and many others as probably Newton's own work, but was in fact copied from an unpublished manuscript of George Starkey: see Newman, 'Newton's "Clavis"' (and Dobbs's acknowledgment of the reattribution, Janus Faces, 15).
