--In the first few years
after the strict and systematic examination of competitive
chronometers, beginning with 1856, the accuracy of chronometers was
greatly increased. For many years past it has been nearly
stationary. I interpret this as shewing that the effects of bad
workmanship are almost eliminated, and that future improvement must be
sought in change of some points of construction.--Referring to the
Transit of Venus in 1874, the printing of all sections of the
Observations, with specimens of the printed forms employed, and
remarks on the photographic operations, is very nearly completed. An
Introduction is begun in manuscript. I am in correspondence with the
Commission which is entrusted with the arrangements for observation of
the Transit of 1882.--The Numerical Lunar Theory has been much
interrupted by the pressure of the Transit of Venus work and other
business."--In his Report to the Board of Visitors (his 46th and
last), Airy remarks that it would be a fitting opportunity for the
expression of his views on the general objects of the Observatory, and
on the duties which they impose on all who are actively concerned in
its conduct. And this he proceeds to do in very considerable
detail.
