Mural Circle was established at work,
a second assistant (Mr Glaisher) was appointed, and the Observatory
might be considered complete. I made experiments on the graduations of
the Circle. I detected and was annoyed by the R--D. I determined the
latitude. I exhibited the separate results for N.P.D. of stars in
ledger, and their means in Catalogue. I investigated from my
observations the place of equinox and the obliquity of the ecliptic.
I made another series of observations of Jupiter's 4th Satellite, for
the mass of Jupiter. I observed the solar eclipse with the Equatoreal,
by a method then first introduced, which I have since used several
times at Cambridge and Greenwich with excellent effect. The Moon and
the Planets were usually observed till near two in the morning.
Correction for defective illumination applied when necessary.
The volume is very complete, the only deficiency being in
the observation of Moon and Planets through the severe morning
hours. In 1834 the only novelties are--examination of the graduations
of the declination circle of the Equatoreal (excessively bad):
observations of a spot on Jupiter for rotation, and of Mars and
stars. In 1835 (including January 1836) there is a more complete
examination of the Equatoreal graduations: parallax and refraction for
Equatoreal observations: a spot on Jupiter: a series of observations
on Jupiter's 4th Satellite for the mass of Jupiter: Mars and stars:
Halley's Comet (the best series of observations which could be made in
the season): and a short series of meteorological observations, on a
plan suggested by Sir John Herschel then at the Cape of Good Hope.

"I cannot tell precisely in which year I introduced the following
useful custom. Towards the end of each year I procured a pocket-book
for the following year with a space for every day, and carefully
examining all the sources of elements of observations, and determining
the observations to be made every day, I inserted them in the
pocket-book. This system gave wonderful steadiness to the plan of
observations for the next year. The system has been maintained in
great perfection at the Observatory of Greenwich. (The first of these
pocket-books which Prof. Adams has found is that for 1833.) Printed
skeleton forms were introduced for all calculations from 1828. In the
Greenwich Observatory Library there is a collection, I believe
complete, of printed papers commencing with my manifesto, and
containing all Syndi
