Clock by Thomas Tompion, London, ca. 1675.
As the most accurate clock at Harvard in 1761, this one-hundred-year old, "excellent pendulum clock" was taken to Newfoundland by John Winthrop to observe the Transit of Venus in 1761.
In 1769, Winthrop considered sending it on a transit expedition to Lake Superior with a Harvard tutor. The expedition was cancelled, and Winthrop observed the Transit from Cambridge with a better clock by Ellicott.
