My sister also lived with me at the
Observatory."
1840
"In the latter part of 1839, and through 1840, I had much
correspondence with the Admiralty, in which I obtained a complete
account of the transfer of the Observatory from the Ordnance
Department to the Admiralty, and the transfer of the Visitation of the
Observatory from the Royal Society to the present Board of
Visitors. In 1840 I found that the papers of the Board of Longitude
were divided between the Royal Society and the Admiralty: I obtained
the consent of both to bring them to the Observatory.
"In this year I began to arrange about an annual dinner to be held at
the Visitation.--My double-image micrometer was much used for
observations of circumpolar double stars.--In Magnetism and
Meteorology, certain quarterly observations were kept up; but in
November the system of incessant eye-observations was commenced. I
refused to commence this until I had secured a 'Watchman's Clock' for
mechanical verification of the regular attendance of the
Assistants.--With regard to chronometers: In this year, for the first
time, I took the very important step of publishing the rates obtained
by comparisons at the Observatory.
