Autobiography of Sir George Biddell Airy - George Biddell Airy (android based ebook reader txt) 📗

information of all kinds from the Encyclopaedia Londinensis, a work which without being high in any respect is one of the most generally useful that I have seen. But I well remember one of the most important steps that I ever made. I had tried experiments with the object-glass of an opera-glass and was greatly astonished at the appearance of the images of objects seen through the glass under different conditions. By these things my thoughts were turned to accurate optics, and I read with care Rutherford's Lectures, which my uncle possessed. The acquisition of an accurate knowledge of the effect of optical constructions was one of the most charming attainments that I ever reached. Long before I went to College I understood the action of the lenses of a telescope better than most opticians. I also read with great zeal Nicholson's Dictionary of Chemistry, and occasionally made chemical experiments of an inexpensive kind: indeed I grew so fond of this subject that there was some thought of apprenticing me to a chemist. I also attended to surveying and made a tolerable survey and map of my uncle's farm.

"At school I was going on successfully, and distinguished myself particularly by my memory. It was the custom for each boy once a week to repeat a number of lines of Latin or Greek poetry, the number depending very much on his own choice. I determined on repeating 100 every week, and I never once fell below that number and was sometimes much above it. It was no distress to me, and great enjoyment. At Michaelmas 1816 I repeated 2394 lines, probably without missing a word. I do not think that I was a favourite with Mr Crosse, but he certainly had a high opinion of my powers and expressed this to my father. My father entertained the idea of sending me to College, which Mr Crosse recommended: but he heard from some college man that the expense would be _L200_ a year, and he laid aside all thoughts of it.

"The farm of Playford Hall was in 1813 or 1814 hired by Thomas Clarkson, the slave-trade abolitionist. My uncle transacted much business for him (as a neighbour and friend) in the management of the farm &c. for a time, and they became very intimate. My uncle begged him to examine me in Classical knowledge, and he did so, I think, twice. He also gave some better information about the probable expenses &c. at College. The result was a strong recommendation by my uncle or through my uncle that I should be sent to Cambridge, and this was adopted by my father. I think it likely that this was in 1816.

"In December 1816, Dealtry's Fluxions was bought for me, and I read it and understood it well. I borrowed Hutton's Course of Mathematics of old Mr Ransome, who had come to reside at Greenstead near Colchester, and read a good deal of it.

"About Ladyday 1817 I began to read mathematics with Mr Rogers (formerly, I think, a Fellow of Sidney College, and an indifferent mathematician of the Cambridge school), who had succeeded a Mr Tweed as assistant to Mr Crosse in the school. I went to his house twice a week, on holiday afternoons. I do not remember how long I received lessons from him, but I think to June, 1818. This course was extremely valuable to me, not on account of Mr Rogers's abilities (for I understood many things better than he did) but for its training me both in Cambridge subjects and in the Cambridge accurate methods of treating them. I went through Euclid (as far as usually read), Wood's Algebra, Wood's Mechanics, Vince's Hydrostatics, Wood's Optics, Trigonometry (in a geometrical treatise and also in Woodhouse's algebraical form), Fluxions to a good extent, Newton's Principia to the end of the 9th section. This was a large quantity, but I read it accurately and understood it perfectly, and could write out any one of the propositions which I had read in the most exact form. My connexion with Mr Rogers was terminated by _his_ giving me notice that he could not undertake to receive me any longer: in fact I was too much for him. I generally read these books in a garret in our house in George Lane, which was indefinitely appropriated to my brother and myself. I find that I copied out Vince's Conic Sections in February, 1819. The first book that I copied was the small geometrical treatise on Trigonometry, in May, 1817: to this I was urged by old Mr Ransome, upon my complaining that I could not purchase the book: and it was no bad lesson of independence to me."

During the same period 1817-1819 he was occupied at school on translations into blank verse from the Aeneid and Iliad, and read through the whole of Sophocles very carefully.

The classical knowledge which he thus gained at school and subsequently at Cambridge was sound, and he took great pleasure in it: throughout his life he made a practice of keeping one or other of the Classical Authors at hand for occasional relaxation. He terminated his schooling in June 1819. Shortly afterwards his father left Colchester and went to reside at Bury St Edmund's. The Autobiography proceeds as follows:

"Mr Clarkson was at one time inclined to recommend me to go to St Peter's College (which had been much enriched by a bequest from a Mr Gisborne). But on giving some account of me to his friend Mr James D. Hustler, tutor of Trinity College, Mr Hustler urged upon him that I was exactly the proper sort of person to go to Trinity College. And thus it was settled (mainly by Mr Clarkson) that I should be entered at Trinity College. I think that I was sent for purposely from Colchester to Playford, and on March 6th, 1819, I rode in company with Mr Clarkson from Playford to Sproughton near Ipswich to be examined by the Rev. Mr Rogers, incumbent of Sproughton, an old M.A. of Trinity College; and was examined, and my certificate duly sent to Mr Hustler; and I was entered on Mr Hustler's side as Sizar of Trinity College.

"In the summer of 1819 I spent some time at Playford. On July 27th, 1819 (my birthday, 18 years old), Mr Clarkson invited me to dinner, to meet Mr Charles Musgrave, Fellow of Trinity College, who was residing for a short time at Grundisburgh, taking the church duty there for Dr Ramsden, the Rector. It was arranged that I should go to Grundisburgh the next day (I think) to be examined in mathematics by Mr Musgrave. I went accordingly, and Mr Musgrave set before me a paper of questions in geometry, algebra, mechanics, optics, &c. ending with the first proposition of the Principia. I knew nothing more about my answers at the time; but I found long after that they excited so much admiration that they were transmitted to Cambridge (I forget whether to Mr Musgrave's brother, a Fellow of Trinity College and afterwards Archbishop of York, or to Mr Peacock, afterwards Dean of Ely) and were long preserved.

"The list of the Classical subjects for the first year in Trinity College was transmitted to me, as usual, by Mr Hustler. They were--The Hippolytus of Euripides, the 3rd Book of Thucydides, and the 2nd Philippic of Cicero. These I read carefully and noted before going up. Mr Hustler's family lived in Bury; and I called on him and saw him in October, introduced by Mr Clarkson. On the morning of October 18th, 1819, I went on the top of the coach to Cambridge, knowing nobody there but Mr Hustler, but having letters of introduction from Mr Charles Musgrave to Professor Sedgwick, Mr Thomas Musgrave, and Mr George Peacock, all Fellows of Trinity College.

"I was set down at the Hoop, saw Trinity College for the first time, found Mr Hustler, was conducted by his servant to the robe-maker's, where I was invested in the cap and blue gown, and after some further waiting was installed into lodgings in Bridge Street. At 4 o'clock I went to the College Hall and was introduced by Mr Hustler to several undergraduates, generally clever men, and in the evening I attended Chapel in my surplice (it being St Luke's day) and witnessed that splendid service of which the occasional exhibition well befits the place.

"As soon as possible, I called on Mr Peacock, Mr Musgrave, and Professor Sedgwick. By all I was received with great kindness: my examination papers had been sent to them, and a considerable reputation preceded me. Mr Peacock at once desired that I would not consider Mr C. Musgrave's letter as an ordinary introduction, but that I would refer to him on all occasions. And I did so for several years, and always received from him the greatest assistance that he could give. I think that I did not become acquainted with Mr Whewell till the next term, when I met him at a breakfast party at Mr Peacock's. Mr Peacock at once warned me to arrange for taking regular exercise, and prescribed a walk of two hours every day before dinner: a rule to which I attended regularly, and to which I ascribe the continuance of good general health.

"I shewed Mr Peacock a manuscript book which contained a number of original Propositions which I had investigated. These much increased my reputation (I really had sense enough to set no particular value on it) and I was soon known by sight to almost everybody in the University. A ridiculous little circumstance aided in this. The former rule of the University (strictly enforced) had been that all students should wear drab knee-breeches: and I, at Mr Clarkson's recommendation, was so fitted up. The struggle between the old dress and the trowsers customary in society was still going on but almost terminated, and I was one of the very few freshmen who retained the old habiliments. This made me in some measure distinguishable: however at the end of my first three terms I laid these aside.

"The College Lectures began on Oct. 22: Mr Evans at 9 on the Hippolytus, and Mr Peacock at 10 on Euclid (these being the Assistant Tutors on Mr Hustler's side): and then I felt myself established.

"I wrote in a day or two to my uncle Arthur Biddell, and I received from him a letter of the utmost kindness. He entered gravely on the consideration of my prospects, my wants, &c.: and offered at all times to furnish me with money, which he thought my father's parsimonious habits might make him unwilling to do. I never had occasion to avail myself of this offer: but it was made in a way which in no small degree strengthened the kindly feelings that had long existed between us.

"I carefully attended the lectures, taking notes as appeared necessary. In Mathematics there were geometrical problems, algebra, trigonometry (which latter subjects the lectures did not reach till the terms of 1820). Mr Peacock gave me a copy of Lacroix's Differential Calculus as translated by himself and Herschel and Babbage, and also a copy of their Examples. At this time, the use of Differential Calculus was just prevailing over that of Fluxions (which I had learnt). I betook myself to it with great industry. I also made myself master of the theories of rectangular coordinates and some of the differential processes applying to them, which only a few of the best of the university mathematicians then wholly possessed. In Classical subjects I read the Latin (Seneca's) and English Hippolytus, Racine's Phedre (which my sister translated for me), and all other books to which I was referred, Aristotle, Longinus, Horace, Bentley, Dawes &c., made verse translations of the Greek Hippolytus, and was constantly on the watch to read
