Autobiography of Sir George Biddell Airy - George Biddell Airy (best novel books to read TXT) 📗

to introduce into printed astronomical observations was partially introduced into this volume, and was steadily improved in subsequent volumes. I think that I am justified, by letters and other remarks, in believing that this introduction of an orderly system of exhibition, not merely of observations but of the steps for bringing them to a practical result--quite a novelty in astronomical publications--had a markedly good effect on European astronomy in general.--In Feb. and March I have letters from Young about the Nautical Almanac: he was unwilling to make any great change, but glad to receive any small assistance. South, who had been keeping up a series of attacks on Young, wrote to me to enquire how I stood in engagements of assistance to Young: I replied that I should assist Young whenever he asked me, and that I disapproved of South's course.--The date of the first visitation of the (Cambridge) Observatory must have been near May 11th: I invited South and Baily to my house; South and I were very near quarrelling about the treatment of Young.--In a few days after Dr Young died: I applied to Lord Melville for the superintendence of the Nautical Almanac: Mr Croker replied that it devolved legally upon the Astronomer Royal, and on May 30th Pond wrote to ask my assistance when I could give any. On June 6th I was invited to the Greenwich Visitation, to which I believe I went on the 10th.

"I had long desired to see Switzerland, and I wished now to see some of the Continental Observatories. I was therefore glad to arrange with Mr Lodge, of Magdalene College (perhaps 10 years senior to myself), to make a little tour. Capt. W.H. Smyth and others gave me introductions. I met Lodge in London, and we started for Calais on July 27th 1829. We visited a number of towns in Belgium (at Brussels I saw the beginning of the Observatory with Quetelet), and passed by Cologne, Frankfort, Fribourg, and Basle to Zurich. Thus far we had travelled by diligence or posting: we now procured a guide, and travelled generally on foot. From the 13th to the 31st August we travelled diligently through the well-known mountainous parts of Switzerland and arrived at Geneva on the 31st August. Here I saw M. Gautier, M. Gambard, and the beginning of the Observatory. Mr Lodge was now compelled to return to Cambridge, and I proceeded alone by Chambery to Turin, where I made the acquaintance of M. Plana and saw the Observatory. I then made a tour through north Italy, looking over the Observatories at Milan, Padua, Bologna, and Florence. At Leghorn I took a passage for Marseille in a xebeque, but after sailing for three days the weather proved very unfavourable, and I landed at Spezia and proceeded by Genoa and the Cornici Road to Marseille. At Marseille I saw M. Gambart and the Observatory, and passed by Avignon, Lyons, and Nevers to Orleans, where I visited my old host M. Legarde. Thence by Paris, Beauvais, and Calais to London and Cambridge, where I arrived on the 30th October. I had started with more than L140 and returned with 2s. 6d . The expedition was in many ways invaluable to me.

"On my return I found various letters from scientific men: some approving of my method for the mass of the Moon: some approving highly of my printed observations, especially D. Gilbert, who informed me that they had produced good effect (I believe at Greenwich), and Herschel.--On Nov. 13th I gave the Royal Astronomical Society a Paper about deducing the mass of the Moon from observations of Venus: on Nov. 16th a Paper to the Cambridge Philosophical Society on a correction to the length of a ball-pendulum: and on Dec. 14th a Paper on certain conditions under which perpetual motion is possible.--The engravings for my Figure of the Earth in the Encyclopaedia Metropolitana were dispatched at the end of the year. Some of the Paper (perhaps much) was written after my return from the Continent.--I began, but never finished, a Paper on the form of the Earth supposed to be projecting at middle latitudes. In this I refer to the printed Paper which Nicollet gave me at Paris. I believe that the investigations for my Paper in the Encyclopaedia Metropolitana led me to think the supposition unnecessary.--On Nov. 6th I was elected member of the Geological Society.

"On Nov. 16th 1829 notice was given of a Grace to authorize payment to me of L157. 9s. 1d. , in conformity with the regulations adopted on Feb. 27th, and on Nov. 18th the Grace passed the Senate. On Nov. 19th the Vice-Chancellor wrote me a note enclosing the cheque. On Nov. 23rd (practically the first day on which I could go) I went to London and travelled to Edensor, where I arrived on the 26th. Here I found Richarda Smith, proposed to her, and was accepted. I stayed there a few days, and returned to Cambridge."


1830

"On Jan. 25th 1830 the Smith's Prize Paper was prepared. I was (with my Assistant, Mr Baldrey) vigorously working the Transit Instrument and its reductions, and gradually forming a course of proceeding which has had a good effect on European Astronomy. And I was preparing for my marriage.

"On Mar. 11th I started with my sister to London, and arrived at Edensor on the afternoon of the 14th. On the 17th I started alone for Manchester and Liverpool. Through Mr Mason, a cotton-spinner at Calver, near Edensor, I had become acquainted with Mr John Kennedy of Manchester, and I had since 1824 been acquainted with Dr Traill of Liverpool. Amongst other things, I saw the works of the Manchester and Liverpool Railway, then advancing and exciting great interest, and saw George Stephenson and his son. On Mar. 24th I was married to Richarda Smith by her father in Edensor. We stopped at Edensor till Apr. 1st, and then started in chaises by way of Newark and Kettering (where we were in danger of being stopped by the snow), and arrived at Cambridge on Apr. 3rd.

"I was now busy in preparing for lectures, especially the part of the optical lectures which related to the theory of interferences and polarization. I think it was now that my wife drew some of my lecture pictures, exhibiting interference phenomena. My lectures began on Apr. 26th and finished on May 24th. The number of names was 50. They were considered an excellent course of lectures.

"May 9th is the date of my Preface to the 1829 Observations: all was then printed. Apparently I did not go to the Visitation of the Greenwich Observatory this year.--I was at this time pressing Tulley, the optician, about an object-glass for the Mural Circle.--A new edition of my 'Tracts' was wanted, and I prepared to add a Tract on the Undulatory Theory of Light in its utmost extent. The Syndicate of the University Press intimated through Dr Turton that they could not assist me (regarding the book as a second edition). On July 10th I have some negociation about it with Deighton the bookseller.--On May 18th I have a note from Whewell about a number of crystals of plagiedral quartz, in which he was to observe the crystalline indication, and I the optical phenomena.--The Report of the Syndicate for visiting the Observatory is dated June 18th: it is highly laudatory.--The Proctor (Barnard of King's College) requested me to name the Moderator for the next B.A. Examination: I named Mr Challis.

"On June 14th my wife and I went, in company with Professor and Mrs Henslow, to London and Oxford; at Oxford we were received in Christchurch College by Dr and Mrs Buckland. My wife and I then went to Bedford to visit Capt. and Mrs Smyth, and returned to Cambridge on the 23rd. On July 5th we went on a visit to my mother and uncle at Playford. While there I took a drive with my uncle into some parts near the valley of the Gipping, in which I thought that the extent of the chalk was inadequately exhibited on Greenough's map, and communicated my remarks to Buckland.

"I find letters from Dr Robinson and Col. Colby about determining longitudes of certain observatories by fire signals: I proposed chronometers as preferable. Also from Herschel, approving of my second volume of observations: and from F. Baily, disclaiming the origination of the attack on the old Nautical Almanac (with which I suppose I had reproached him). On July 30th I received a summons from South to a committee for improving the Nautical Almanac; and subsequently a letter from Baily about Schumacher's taking offence at a passage of mine in the Cambridge Observations, on the comparative merits of Ephemerides, which I afterwards explained to his satisfaction.

"On Aug. 24th my wife and I started for Edensor, and after a short stay there proceeded by Manchester to Cumberland, where we made many excursions. We returned by Edensor, and reached Cambridge on Oct. 6th, bringing my wife's sister Susanna on a visit. My mother had determined, as soon as my intention of marriage was known to her, to quit the house, although always (even to her death) entertaining the most friendly feelings and fondness for my wife. It was also judged best by us all that my sister should not reside with us as a settled inhabitant of the house. They fixed themselves therefore at Playford in the farm-house of the Luck's Farm, then in the occupation of my uncle Arthur Biddell. On Oct. 21st I have a letter from my sister saying that they were comfortably settled there.

"In this month of October (principally, I believe) I made some capital Experiments on Quartz, which were treated mathematically in a Paper communicated in the next year to the Cambridge Philosophical Society. In some of these my wife assisted me, and also drew pictures.--On Nov. 15th the Grace for paying me L198. 13s. 8d. to make my income up to L500 passed the Senate.--I made three journeys to London to attend committees, one a committee on the Nautical Almanac, and one a Royal Society Committee about two southern observatories.--On Dec. 31st I have a letter from Maclear (medical practitioner and astronomer at Biggleswade) about occultations.--In this December I had a quartz object-glass by Cauchaix mounted by Dollond, and presented it to the Observatory.--In this December occurred the alarm from agrarian fires. There was a very large fire at Coton, about a mile from the Observatory. This created the most extraordinary panic that I ever saw. I do not think it is possible, without having witnessed it, to conceive the state of men's minds. The gownsmen were all armed with bludgeons, and put under a rude discipline for a few days."


1831

"On Jan. 4th I went with my wife, first to Miss Sheepshanks in London, at 30, Woburn Place, and next to the house of my wife's old friend, the Rev. John Courtney, at Sanderstead, near Croydon. I came to London on one day to attend a meeting of the new Board of Visitors of the Greenwich Observatory. Formerly the Board of Visitors consisted of the Council of the Royal Society with persons invited by them (in which capacity I had often attended). But a reforming party, of which South, Babbage, Baily and Beaufort were prominent members, had induced the Admiralty to constitute a new Board, of which the Plumian Professor was
