Timing & context
A note on this hour
Frequent indoor pacing, distinct from his rare garden walks.
Cambridge · the Principia years · Assistant’s retrospective account
Humphrey recalled about five years of service. His account gives habits rather than a timetable; occasional garden walks remain labelled as such.
1686 represents the 1680s period when Humphrey Newton assisted him; it is not the date of a recorded day.
