Autobiography of Sir George Biddell Airy, George Biddell Airy [dark books to read TXT] 📗

Auckland and Mr Wood expressed their feeling, that the Observatory had fallen into such a state of disrepute that the whole establishment ought to be cleared out. I represented that I could make it efficient with a good First Assistant; and the other Assistants were kept. But the establishment was in a queer state. The Royal Warrant under the Sign Manual was sent on August 11th. It was understood that my occupation of office would commence on October 1st, but repairs and alterations of buildings would make it impossible for me to reside at Greenwich before the end of the year. On Oct. 1st I went to the Observatory, and entered formally upon the office (though not residing for some time). Oct 7th is the date of my Official Instructions.

"I had made it a condition of accepting the office that the then First Assistant should be removed, and accordingly I had the charge of seeking another. I determined to have a man who had taken a respectable Cambridge degree. I made enquiry first of Mr Bowstead (brother to the bishop) and Mr Steventon: at length, consulting Mr Hopkins (a well-known private tutor at Cambridge), he recommended to me Mr Robert Main, of Queens' College, with whom I corresponded in the month (principally) of August, and whom on August 30th I nominated to the Admiralty. On Oct. 21st F.W. Simms, one of the Assistants (who apparently had hoped for the office of First Assistant, for which he was quite incompetent) resigned; and on Dec. 4th I appointed in his place Mr James Glaisher, who had been at Cambridge from the beginning of 1833, and on Dec. 10th the Admiralty approved.

"During this quarter of a year I was residing at Cambridge Observatory, visiting Greenwich once a week (at least for some time), the immediate superintendence of the Observatory being placed with Mr Main. I was however engaged in reforming the system of the Greenwich Observatory, and prepared and printed 30 skeleton forms for reductions of observations and other business. On Dec. 14th I resigned my Professorship to the Vice-Chancellor. But I continued the reduction of the observations, so that not a single figure was left to my successor: the last observations were those of Halley's Comet. The Preface to my 1835 Cambridge Observations is dated Aug. 22nd, 1836.

"In regard to the Northumberland Telescope, I had for some time been speculating on plans of mounting and enclosing the instrument, and had corresponded with Simms, A. Biddell, Cubitt, and others on the subject. On Apr. 24th Tulley the younger was endeavouring to adjust the object-glass. On May 31st I plainly asked the Duke of Northumberland whether he would defray the expense of the mounting and building. On June 4th he assented, and money was placed at a banker's to my order. I then proceeded in earnest: in the autumn the building was erected, and the dome was covered before the depth of winter. I continued in 1836 to superintend the mounting of the instrument.

"In regard to the Planetary Reductions: to July 11th J. Glaisher had been employed 27 weeks, and from July 11th to Jan. 16th, 1836, 25 weeks. Mr Spring Rice, when Chancellor of the Exchequer, had promised money, but no official minute had been made, and no money had been granted. On Aug. 21st I applied to Mr Baring (Secretary of the Treasury). After another letter he answered on Oct. 15th that he found no official minute. After writing to Vernon Harcourt and to Spring Rice, the matter was arranged: my outlay was refunded, and another sum granted.--In regard to Groombridge's Observations, I find that on Dec. 16th certain trial reductions had been made under my direction by J. Glaisher.--I had attempted some optical experiments in the summer, especially on the polarization of sky-light; but had been too busy with the Observatory to continue them.

"In August my wife was in a critical state of health.--In December I received information regarding merchant ships' chronometers, for which I had applied to Mr Charles Parker of Liverpool.--On Dec. 8th Mr Spring Rice and Lord John Russell offered me knighthood, but I declined it.--On July 23rd I went into Suffolk with my wife's sisters Elizabeth and Georgiana, and returned on August 3rd: this was all the holiday that I got in this year.--On the 14th of August I saw Mr Taylor, the Admiralty Civil Architect in London, and the extension of buildings at Greenwich Observatory was arranged.--I made various journeys to Greenwich, and on Dec. 17th, having sent off our furniture, we all quitted the Cambridge Observatory, and stayed for some days at the house of Miss Sheepshanks.

"Thus ended a busy and anxious year."

With reference to the offer of knighthood above-mentioned, Airy's reply is characteristic, and the short correspondence relating to it is therefore inserted.--The offer itself is an additional proof of the high estimation in which he stood at this time.

DOWNING STREET,
_Dec. 8th 1835_.

MY DEAR SIR,

I have been in communication with my colleague Lord John Russell which has made me feel rather anxious to have the pleasure of seeing you, but on second thoughts it has occurred to me that the subject of my communication would render it more satisfactory to you to receive a letter than to pay a visit.

In testimony of the respect which is felt for your character and acquirements, there would be every disposition to recommend you to His Majesty to receive the distinction of Knighthood. I am quite aware that to you individually this may be a matter of small concern, but to the scientific world in general it will not be indifferent, and to foreign countries it will mark the consideration felt for you personally as well as for the position which you occupy among your learned contemporaries.

From a knowledge of the respect and esteem which I feel for you Lord John Russell has wished that the communication should be made through me rather than through any person who had not the pleasure of your acquaintance.

Pray let me hear from you and believe me my dear Sir, with compliments to Mrs Airy,

Very truly yours,
T. SPRING RICE.

P.S.--It may be right to add that when a title of honor is conferred on grounds like those which apply to your case, no fees or charges of any kind would be payable.


OBSERVATORY, CAMBRIDGE,
_1835, Dec. 10th_.

MY DEAR SIR,

I beg to acknowledge your letter of the 8th, which I have received at this place, conveying to me an intimation of the wish of His Majesty's Ministers to recommend me to the King for the honor of Knighthood.

I beg to assure you that I am most sensible to the liberality which I have experienced from the Government in other as well as in pecuniary matters, and that I am very highly gratified by the consideration (undeserved by me, I fear) which they have displayed in the present instance. And if I now request permission to decline the honor offered to me, I trust I may make it fully understood that it is not because I value it lightly or because I am not anxious to receive honors from such a source.

The unalterable custom of this country has attached a certain degree of light consideration to titles of honor which are not supported by considerable fortune; or at least, it calls for the display of such an establishment as may not be conveniently supported by even a comfortable income. The provision attached to my official situation, and the liberality of the King towards one of the members of my family, have placed me in a position of great comfort. These circumstances however have bound me to consider myself as the devoted servant of the country, and to debar myself from efforts to increase my fortune which might otherwise have been open to me. I do not look forward therefore to any material increase of income, and that which I enjoy at present is hardly sufficient, in my opinion, to support respectably the honor which you and Lord John Russell have proposed to confer upon me. For this reason only I beg leave most respectfully to decline the honor of Knighthood at the present time.

I have only to add that my services will always be at the command of the Government in any scientific subject in which I can be of the smallest use.

I am, my dear Sir,
Your very faithful Servant,
G.B. AIRY.

_The Right Honorable T. Spring Rice_.

"In brief revision of the years from 1827 to 1835 I may confine myself to the two principal subjects--my Professorial Lectures, and my Conduct of the Cambridge Observatory.

"The Lectures as begun in 1827 included ordinary Mechanics, ordinary Hydrostatics and Pneumatics (I think that I did not touch, or touched very lightly, on the subjects connected with the Hydraulic Ram), and ordinary Optics (with a very few words on Polarization and Depolarization). In 1828 the two first were generally improved, and for the third (Optics) I introduced a few words on Circular Polarization. I believe that it was in 1829 that I made an addition to the Syllabus with a small engraving, shewing the interference of light in the best practical experiment (that of the flat prism); and I went thoroughly into the main points of the Undulatory Theory, interference, diffraction, &c. In 1830 I believe I went (in addition to what is mentioned above) into Polarization and Depolarization of all kinds. My best lecture diagrams were drawn and painted by my wife. The Lectures were universally pronounced to be valuable. The subjects underwent no material change in 1831, 2, 3, 4, 5; and I believe it was a matter of sincere regret to many persons that my removal to Greenwich terminated the series. Each lecture nominally occupied an hour. But
