--Towards the end of the year I
observed Encke's Comet: and determined the latitude of the Observatory
with Sheepshanks's repeating circle.--On my papers I find a sketch of
an Article on the Figure of the Earth for the Encyclopaedia
Metropolitana.
"As early as Feb. 23rd I had been in correspondence with T. Jones, the
instrument-maker, about pendulums for a repetition of the Dolcoath
Experiments. Invitations had been received, and everything was
arranged with Whewell. Sheepshanks, my brother, and Mr Jackson of
Ipswich (Caius Coll.) were to go, and we were subsequently joined by
Sedgwick, and Lodge (Magdalene Coll.). On July 3rd Sheepshanks and I
started by Salisbury, taking Sherborne on our way to look at the
church, which had alarmed the people by signs of a crack, and arrived
at Camborne on July 8th. On the 14th we set up the pendulums, and at
once commenced observations, our plan being, to have no intermission
in the pendulum observations, so that as soon as the arc became too
small a fresh series was started. On July 29th we raised the
instruments, and Sheepshanks, who managed much of the upper
operations, both astronomical and of pendulums, mounted the pendulums
together in his observatory.
