PRINTED PAPERS BY G.B.  AIRY.

With the instinct of order which formed one of his chief characteristics Airy carefully preserved a copy of every printed Paper of his own composition.  These were regularly bound in large quarto volumes, and they are in themselves a striking proof of his wonderful diligence.  The bound volumes are 14 in number, and they occupy a space of 2 ft. 6 in. on a shelf.  They contain 518 Papers, a list of which is appended, and they form such an important part of his life’s work, that his biography would be very incomplete without a reference to them.

He was very careful in selecting the channels for the publication of his Papers.  Most of the early Papers were published in the Transactions of the Cambridge Philosophical Society, but several of the most important, such as his Paper “On an inequality of long period in the motions of the Earth and Venus,” were published in the Philosophical Transactions of the Royal Society, and others, such as the articles on “The Figure of the Earth,” “Gravitation,” “Tides and Waves,” &c., were published in Encyclopaedias.  After his removal to Greenwich nearly all his Papers on scientific subjects (except astronomy), such as Tides, Magnetism, Correction of the Compass, &c., &c., were communicated to the Royal Society, and were published in the Philosophical Transactions.  But everything astronomical was reserved for the Royal Astronomical Society.  His connection with that Society was very close:  he had joined it in its earliest days (the date of his election was May 9th, 1828), and regarded it as the proper medium for the discussion of current astronomical questions, and for recording astronomical progress.  He was unremitting in his attendance at the Monthly Meetings of the Society, and was several times President.  In the Memoirs of the Society 35 of his Papers are printed, and in addition 129 Papers in the Monthly Notices.  In fact a meeting of the Society rarely passed without some communication from him, and such was his wealth of matter that sometimes he would communicate as many as 3 Papers on a single evening.  For the publication of several short mathematical Papers, and especially for correspondence on disputed points of mathematical investigation, he chose as his vehicle the Philosophical Magazine, to which he contributed 32 Papers.  Investigations of a more popular character he published in the Athenaeum, which he also used as a vehicle for his replies to attacks on his work, or on the Establishment which he conducted:  in all he made 55 communications to that Newspaper.  To various Societies, such as the Institution of Civil Engineers, the British Association, the Royal Institution, &c., he presented Papers or made communications on subjects specially suited to each; and in like manner to various
