Autobiography of Sir George Biddell Airy, George Biddell Airy [best english books to read for beginners txt] 📗

of music and knew a great number of songs; and he was well acquainted with the theory of music: but he was no performer. He did not sketch freehand but made excellent drawings with his Camera Lucida.

At the time when he took his degree (1823) and for many years afterwards there was very great activity of scientific investigation and astronomical enterprise in England. And, as in the times of Flamsteed and Halley, the earnest zeal of men of science occasionally led to much controversy and bitterness amongst them. Airy was by no means exempt from such controversies. He was a man of keen sensitiveness, though it was combined with great steadiness of temper, and he never hesitated to attack theories and methods that he considered to be scientifically wrong. This led to differences with Ivory, Challis, South, Cayley, Archibald Smith, and others; but however much he might differ from them he was always personally courteous, and the disputes generally went no farther than as regarded the special matter in question. Almost all these controversial discussions were carried on openly, and were published in the Athenaeum, the Philosophical Magazine, or elsewhere; for he printed nearly everything that he wrote, and was very careful in the selection of the most suitable channels for publication. He regarded it as a duty to popularize as much as possible the work done at the Observatory, and to take the public into his confidence. And this he effected by articles communicated to newspapers, lectures, numerous Papers written for scientific societies, reports, debates, and critiques.

His strong constitution and his regular habits, both of work and exercise, are sufficient explanation of the good health which in general he enjoyed. Not but what he had sharp touches of illness from time to time. At one period he suffered a good deal from an attack of eczema, and at another from a varicose vein in his leg, and he was occasionally troubled with severe colds. But he bore these ailments with great patience and threw them off in course of time. He was happy in his marriage and in his family, and such troubles and distresses as were inevitable he accepted calmly and quietly. In his death, as in his life, he was fortunate: he had no long or painful illness, and he was spared the calamity of aberration of intellect, the saddest of all visitations.


CHAPTER II.

FROM HIS BIRTH TO HIS TAKING HIS B.A. DEGREE AT CAMBRIDGE.

FROM JULY 27TH 1801 TO JANUARY 18TH 1823.


George Biddell Airy was born at Alnwick in Northumberland on July 27th 1801. His father was William Airy of Luddington in Lincolnshire, the descendant of a long line of Airys who have been traced back with a very high degree of probability to a family of that name which was settled at Kentmere in Westmorland in the 14th century. A branch of this family migrated to Pontefract in Yorkshire, where they seem to have prospered for many years, but they were involved in the consequences of the Civil Wars, and one member of the family retired to Ousefleet in Yorkshire. His grandson removed to Luddington in Lincolnshire, where his descendants for several generations pursued the calling of small farmers. George Biddell Airy's mother, Ann Airy, was the daughter of George Biddell, a well-to-do farmer in Suffolk.

William Airy, the father of George Biddell Airy, was a man of great activity and strength, and of prudent and steady character. When a young man he became foreman on a farm in the neighbourhood of Luddington, and laid by his earnings in summer in order to educate himself in winter. For a person in his rank, his education was unusually good, in matters of science and in English literature. But at the age of 24 he grew tired of country labour, and obtained a post in the Excise. After serving in various Collections he was appointed Collector of the Northumberland Collection on the 15th August 1800, and during his service there his eldest son George Biddell Airy was born. The time over which his service as Officer and Supervisor extended was that in which smuggling rose to a very high pitch, and in which the position of Excise Officer was sometimes dangerous. He was remarkable for his activity and boldness in contests with smugglers, and made many seizures. Ann Airy, the mother of George Biddell Airy, was a woman of great natural abilities both speculative and practical, kind as a neighbour and as head of a family, and was deeply loved and respected. The family consisted of George Biddell, Elizabeth, William, and Arthur who died young.

William Airy was appointed to Hereford Collection on 22nd October 1802, and removed thither shortly after. He stayed at Hereford till he was appointed to Essex Collection on 28th February 1810, and during this time George Biddell was educated at elementary schools in writing, arithmetic, and a little Latin. He records of himself that he was not a favourite with the schoolboys, for he had very little animal vivacity and seldom joined in active play with his schoolfellows. But in the proceedings of the school he was successful, and was a favourite with his master.

On the appointment of William Airy to Essex Collection, the family removed to Colchester on April 5th 1810. Here George Biddell was first sent to a large school in Sir Isaac's Walk, then kept by Mr Byatt Walker, and was soon noted for his correctness in orthography, geography, and arithmetic. He evidently made rapid progress, for on one occasion Mr Walker said openly in the schoolroom how remarkable it was that a boy 10 years old should be the first in the school. At this school he stayed till the end of 1813 and thoroughly learned arithmetic (from Walkingame's book), book-keeping by double entry (on which knowledge throughout his life he set a special value), the use of the sliding rule (which knowledge also was specially useful to him in after life), mensuration and algebra (from Bonnycastle's books). He also studied grammar in all its branches, and geography, and acquired some knowledge of English literature, beginning with that admirable book The Speaker, but it does not appear that Latin and Greek were attended to at this school. He records that at this time he learned an infinity of snatches of songs, small romances, &c., which his powerful memory retained most accurately throughout his life. He was no hand at active play: but was notorious for his skill in constructing guns for shooting peas and arrows, and other mechanical contrivances. At home he relates that he picked up a wonderful quantity of learning from his father's books. He read and remembered much poetry from such standard authors as Milton, Pope, Gay, Gray, Swift, &c., which was destined to prove in after life an invaluable relaxation for his mind. But he also studied deeply an excellent Cyclopaedia called a Dictionary of Arts and Sciences in three volumes folio, and learned from it much about ship-building, navigation, fortification, and many other subjects.

During this period his valuable friendship with his uncle Arthur Biddell commenced. Arthur Biddell was a prosperous farmer and valuer at Playford near Ipswich. He was a well-informed and able man, of powerful and original mind, extremely kind and good-natured, and greatly respected throughout the county. In the Autobiography of George Biddell Airy he states as follows:

"I do not remember precisely when it was that I first visited my uncle Arthur Biddell. I think it was in a winter: certainly as early as the winter of 1812--13. Here I found a friend whose society I could enjoy, and I entirely appreciated and enjoyed the practical, mechanical, and at the same time speculative and enquiring talents of Arthur Biddell. He had a library which, for a person in middle life, may be called excellent, and his historical and antiquarian knowledge was not small. After spending one winter holiday with him, it easily came to pass that I spent the next summer holiday with him: and at the next winter holiday, finding that there was no precise arrangement for my movements, I secretly wrote him a letter begging him to come with a gig to fetch me home with him: he complied with my request, giving no hint to my father or mother of my letter: and from that time, one-third of every year was regularly spent with him till I went to College. How great was the influence of this on my character and education I cannot tell. It was with him that I became acquainted with the Messrs Ransome, W. Cubitt the civil engineer (afterwards Sir W. Cubitt), Bernard Barton, Thomas Clarkson (the slave-trade abolitionist), and other persons whose acquaintance I have valued highly. It was also with him that I became acquainted with the works of the best modern poets, Scott, Byron, Campbell, Hogg, and others: as also with the Waverley Novels and other works of merit."

In 1813 William Airy lost his appointment of Collector of Excise and was in consequence very much straitened in his circumstances. But there was no relaxation in the education of his children, and at the beginning of 1814 George Biddell was sent to the endowed Grammar School at Colchester, then kept by the Rev. E. Crosse, and remained there till the summer of 1819, when he went to College. The Autobiography proceeds as follows:

"I became here a respectable scholar in Latin and Greek, to the extent of accurate translation, and composition of prose Latin: in regard to Latin verses I was I think more defective than most scholars who take the same pains, but I am not much ashamed of this, for I entirely despise the system of instruction in verse composition.

"My father on some occasion had to go to London and brought back for me a pair of 12-inch globes. They were invaluable to me. The first stars which I learnt from the celestial globe were alpha Lyrae, alpha Aquilae, alpha Cygni: and to this time I involuntarily regard these stars as the birth-stars of my astronomical knowledge. Having somewhere seen a description of a Gunter's quadrant, I perceived that I could construct one by means of the globe: my father procured for me a board of the proper shape with paper pasted on it, and on this I traced the lines of the quadrant.

"My command of geometry was tolerably complete, and one way in which I frequently amused myself was by making paper models (most carefully drawn in outline) which were buttoned together without any cement or sewing. Thus I made models, not only of regular solids, regularly irregular solids, cones cut in all directions so as to shew the conic sections, and the like, but also of six-gun batteries, intrenchments and fortresses of various kinds &c.

"From various books I had learnt the construction of the steam-engine: the older forms from the Dictionary of Arts and Sciences; newer forms from modern books. The newest form however (with the sliding steam valve) I learnt from a 6-horse engine at Bawtrey's brewery (in which Mr Keeling the father of my schoolfellow had acquired a partnership). I frequently went to look at this engine, and on one occasion had the extreme felicity of examining some of its parts when it was opened for repair.

"In the mean time my education was advancing at Playford. The first record, I believe, which I have of my attention to mechanics there is the plan of a threshing-machine which I drew. But I was acquiring valuable information of
