iography is in a somewhat disjointed state, and appears to have
been formed by extracts from a number of different sources, such as
Official Journals, Official Correspondence, and Reports. In editing
the Autobiography it has been thought advisable to omit a large number
of short notes relating to the routine work of the Observatory, to
technical and scientific correspondence, to Papers communicated to
various Societies and official business connected with them, and to
miscellaneous matters of minor importance. These in the aggregate
occupied a great deal of time and attention. But, from their detached
nature, they would have but little general interest. At various places
will be found short Memoirs and other matter by the Editor.
(2) All of his Annual Reports to the Board of Visitors are attached to
his Autobiography and were evidently intended to be read with it and
to form part of it. These Reports are so carefully compiled and are so
copious that they form a very complete history of the Greenwich
Observatory and of the work carried on there during the time that he
was Astronomer Royal. The first Report contained only four pages, but
with the constantly increasing amount and range of work the Reports
constantly increased in volume till the later Reports contained 21
pages. Extracts from these Reports relating to matters of novelty and
importance, and illustrating the principles which guided him in his
conduct of the Observatory, have been incorporated with the
Autobiography.
(3) The printed "Papers by G.B. Airy" are bound in 14 large quarto
volumes. There are 518 of these Papers, on a great variety of
subjects: a list of them is appended to this history, as also is a
list of the books that he wrote, and one or two of the Papers which
were separately printed. They form a very important part of his
life's work, and are frequently referred to in the present
history. They are almost all to be found in the Transactions of
Societies or in newspapers, and extend over a period of 63 years (1822
to 1885). The progress made in certain branches of science during this
long period can very fairly be traced by these Papers.
(4) His private correspondence was large, and like his other papers it
was carefully arranged. No business letters of any kind are included
under this head. In this correspondence letters are occasionally found
either dealing with matters of importance or in some way
characteristic, and these have been ins
