but absolutely refusing to claim any religious assent. I expressed this to Dr Jerrard, the principal representative on the religious side, by calling on him to substitute the words 'Recognition of Christian Literature' for 'Recognition of Christian Religion': I addressed a printed letter to Lord Burlington (Chancellor) and the Members of the Senate, on this subject.

"Of private history: In January I made a short excursion in Norfolk and Suffolk, and visited Prof. Sedgwick at Norwich. In April I paid a short visit to Mr Courtney at Sanderstead, with my wife. On June 14th my son Hubert was born. In September I went with my sister by Cambridge, &c., to Luddington, where I made much enquiry concerning my father and the family of Airy who had long been settled there. We then visited various places in Yorkshire, and arrived at Brampton, near Chesterfield, where Mrs Smith, my wife's mother, now resided. And returned by Rugby. I had much correspondence with my brother and for him about private pupils and a better church living. I complained to the Bishop of Norwich about the mutilation of a celebrated monument in Playford Church by the incumbent and curate."

The following extracts are from letters to his wife relating to the above-mentioned journeys:


CLOSE, NORWICH.
_1838, Jan. 21_.

I do not know what degree of cold you may have had last night, but here it was (I believe) colder than before--thermometer close to the house at 3 deg.. I have not suffered at all. However I do not intend to go to Lowestoft.


BRAMPTON.
_1838, Sept. 30th_.

We began to think that we had seen enough of Scarborough, so we took a chaise in the afternoon to Pickering, a small agricultural town, and lodged in a comfortable inn there. On Wednesday morning at 8 we started by the railroad for Whitby, in a huge carriage denominated the Lady Hilda capable of containing 40 persons or more drawn by one horse, or in the steep parts of the railway by two horses. The road goes through a set of defiles of the eastern moorlands of Yorkshire which are extremely pretty: at first woody and rich, then gradually poorer, and at last opening on a black moor with higher moors in sight: descending in one part by a long crooked inclined plane, the carriage drawing up another load by its weight: through a little tunnel: and then along a valley to Whitby. The rate of travelling was about 10 miles an hour. Betsy declares that it was the most agreeable travelling that she ever had.

Yesterday (Saturday) Caroline drove Betsy and Miss Barnes drove me to Clay Cross to see the works at the great railroad tunnel there. Coming from the north, the railroad passes up the Chesterfield valley close by the town and continues up the same valley, till it is necessary for it to enter the valley which runs the opposite way towards Buttersley: the tunnel passes under the high ground between these two vallies: so that it is in reality at the water-shed: it is to be I think more than a mile long, and when finished 27 feet clear in height, so it is a grand place. We saw the preparations for a blast, and heard it fired: the ladies stopping their ears in due form.


1839

"Cambridge Observatory:--On Mar. 7th I went to Cambridge on the business of the Northumberland Telescope: I was subsequently engaged on the accounts, and on Aug. 16th I finally resigned it to Prof. Challis, who accepted it on Aug. 19th. On Sept. 11th I communicated its completion and the settlement of accounts to the Duke of Northumberland. The total expense was _L1938. 9s. 2d._ + 15000 francs for the object-glass.

"At Greenwich Observatory:--On Jan. 3rd I received the last revise of the 1837 Observations, and on Jan. 8th the first sheet for 1838.--In July I report on selection from a long list of chronometers which had been on trial, and on Sept. 2nd I pointed out to Capt. Beaufort that the system of offering only one price would be ruinous to the manufacture of chronometers, and to the character of those supplied to the Admiralty: and that I would undertake any trouble of classifying the chronometers tried. This letter introduced the system still in use (1871), which has been most beneficial to the manufacture. On Sept. 11th I proposed that all trials begin in the first week of January: this also has been in use as an established system to the present time.--It was pointed out to me that a certain chronometer was affected by external magnetic power. I remedied this by placing under it a free compass magnet: a stand was specially prepared for it. I have never found another chronometer sensibly affected by magnetism.--In November and December I tried my new double-image micrometer.--Between May 16th and Oct. 13th a fireproof room was constructed in the southern part of the quadrant room; and in November a small shed was erected over the entrance to the North Terrace.--The position of the free Meridional Magnet (now mounted in the Magnetic Observatory) was observed at every 5 m. through 24 hours on Feb. 22nd and 23rd, May 24th and 25th, Aug. 30th and 31st, and Nov. 29th and 30th. This was done in cooperation with the system of the Magnetic Union established by Gauss in Germany.--The Reduction of the Greenwich Planetary and Lunar Observations, 1750 to 1830, went on steadily. I had six and sometimes seven computers constantly at work, in the Octagon Room.--As in 1838 I had a great amount of correspondence with Mr Baily on the Cavendish Experiment.--I attended as regularly as I could to the business of the University of London. The religious question did not rise very prominently. I took a very active part, and have a great deal of correspondence, on the nature of the intended examinations in Hydrography and Civil Engineering.--On the Standards Commission the chief work was in external enquiries.--On June 6th I had enquiries from John Quincey Adams (U.S.A.) on the expense, &c., of observatories: an observatory was contemplated in America.--I had correspondence about the proposed establishment of observatories at Durham, Glasgow, and Liverpool.

"I had in this year a great deal of troublesome and on the whole unpleasant correspondence with the Admiralty about the correction of the compass in iron ships. I naturally expected some acknowledgment of an important service rendered to Navigation: but the Admiralty peremptorily refused it. My account of the Experiments &c. for the Royal Society is dated April 9th. The general success of the undertaking soon became notorious, and (as I understood) led immediately to extensive building of iron ships: and it led also to applications to me for correction of compasses. On Jan. 9th I was addressed in reference to the Royal Sovereign and Royal George at Liverpool; July 18th the Orwell; May 11th two Russian ships built on the Thames; Sept. 4th the ships of the Lancaster Company.

"I had much work in connection with the Cape of Good Hope Observatory, chiefly relating to the instrumental equipment and to the geodetical work. As it was considered advisable that any base measured in the Cape Colony should be measured with compensation bars, I applied to Major Jervis for the loan of those belonging to the East Indian Survey, but he positively refused to lend them. On Jan. 20th I applied to Col. Colby for the compensation bars of the British Survey, and he immediately assented to lending them. Col. Colby had suggested to the Ordnance Department that Capt. Henderson and several sappers should be sent to use the measuring bars, and it was so arranged. It still appeared desirable to have the command of some soldiers from the Garrison of Cape Town, and this matter was soon arranged with the military authorities by the Admiralty.

"The following are the principal points of my private history: it was a very sad year. On Jan. 24th I went with my wife to Norwich, on a visit to Prof. Sedgwick, and in June I visited Sir J. Herschel at Slough. On June 13th my dear boy Arthur was taken ill: his malady soon proved to be scarlet fever, of which he died on June 24th at 7 in the morning. It was arranged that he should be buried in Playford churchyard on the 28th, and on that day I proceeded to Playford with my wife and my eldest son George Richard. At Chelmsford my son was attacked with slight sickness, and being a little unwell did not attend his brother's funeral. On July 1st at 4h.15m. in the morning he also died: he had some time before suffered severely from an attack of measles, and it seemed probable that his brain had suffered. On July 5th he was buried by the side of his brother Arthur in Playford churchyard.--On July 23rd I went to Colchester on my way to Walton-on-the-Naze, with my wife and all my family; all my children had been touched, though very lightly, with the scarlet fever.--It was near the end of this year that my mother quitted the house (Luck's) at Playford, and came to live with me at Greenwich Observatory, where she lived till her death; having her own attendant, and living in perfect confidence with my wife and myself, and being I trust as happy as her years and widowhood permitted. My sister also lived with me at the Observatory."


1840

"In the latter part of 1839, and through 1840, I had much correspondence with the Admiralty, in which I obtained a complete account of the transfer of the Observatory from the Ordnance Department to the Admiralty, and the transfer of the Visitation of the Observatory from the Royal Society to the present Board of Visitors. In 1840 I found that the papers of the Board of Longitude were divided between the Royal Society and the Admiralty: I obtained the consent of both to bring them to the Observatory.

"In this year I began to arrange about an annual dinner to be held at the Visitation.--My double-image micrometer was much used for observations of circumpolar double stars.--In Magnetism
