I dare say that the Commissioners' Report has taken a very good line of discrimination.

1843
"In March I wrote to Dr Wynter (Vice-Chancellor) at Oxford, requesting permission to see Bradley's and Bliss's manuscript Observations, with the view of taking a copy of them. This was granted, and the books of Transits were subsequently copied under Mr Breen's superintendence. --The following paragraph is extracted from the Report to the Visitors: 'In the Report of last year, I stated that our reductions had dropped considerably in arrear. I have the satisfaction now of stating that this arrear and very much more have been completely recovered, and that the reductions are now in as forward a state as at any time since my connection with the Observatory.' In fact the observations of 1842 were sent to press on Mar. 1st, 1843.--About this year the Annual Dinner at the Visitation began to be more important, principally under the management of Capt. W.H. Smyth, R.N.--In November I was enquiring about an 8-inch object-glass. I had already in mind the furnishing of our meridional instruments with greater optical powers.--On July 14th the Admiralty referred to me a Memorial of Mr J.G. Ulrich, a chronometer maker, claiming a reward for improvements in chronometers. I took a great deal of trouble in the investigation of this matter, by books, witnesses, &c., and finally reported on Nov. 4th that there was no ground for claim.--In April I received the first application of the Royal Exchange Committee, for assistance in the construction of the Clock: this led to a great deal of correspondence, especially with Dent.--The Lunar Reductions were going on in full vigour.--I had much work in connection with the Cape Observatory: partly about an equatoreal required for the Observatory, but chiefly in getting Maclear's work through the press.--In this year I began to think seriously of determining the longitude of Valencia in Ireland, as a most important basis for the scale of longitude in these latitudes, by the transmission of chronometers; and in August I went to Valencia and examined the localities. In September I submitted a plan to the Admiralty, but it was deferred.--The new Commission for restoring the Standards was appointed on June 20th, I being Chairman. The work of collecting standards and arranging plans was going on; Mr Baily attending to Standards of Length, and Prof. W.H. Miller to Standards of Weight. We held two meetings.--A small assistance was rendered to me by Mr Charles May (of the firm of Ransomes and May), which has contributed much to the good order of papers in the Observatory. Mr Robert Ransome had remarked my method of punching holes in the paper by a hand-punch, the places of the holes being guided by holes in a piece of card, and said that they could furnish me with something better. Accordingly, on Aug. 28th Mr May sent me the punching machine, the prototype of all now used in the Observatory.
"On Sept. 25th was made my proposal for an Altazimuth Instrument for making observations of the Moon's place more frequently and through parts of her orbit where she could never be observed with meridional instruments; the most important addition to the Observatory since its foundation. The Board of Visitors recommended it to the Admiralty, and the Admiralty sanctioned the construction of the instrument and the building to contain it." The following passage is quoted from the Address of the Astronomer Royal to the Board of Visitors at the Special Meeting of Nov. 10th, 1843: "The most important object in the institution and maintenance of the Royal Observatory has always been the Observations of the Moon. In this term I include the determination of the places of fixed stars which are necessary for ascertaining the instrumental errors applicable to the instrumental observations of the Moon. These, as regards the objects of the institution, were merely auxiliaries: the history of the circumstances which led the Government of the day to supply the funds for the construction of the Observatory shews that, but for the demands of accurate Lunar Determinations as aids to navigation, the erection of a National Observatory would never have been thought of. And this object has been steadily kept in view when others (necessary as fundamental auxiliaries) were passed by. Thus, during the latter part of Bradley's time, and Bliss's time (which two periods are the least efficient in the modern history of the Observatory), and during the latter part of Maskelyne's presidency (when, for years together, there is scarcely a single observation of the declination of a star), the Observations of the Moon were kept up with the utmost regularity. And the effect of this regularity, as regards its peculiar object, has been most honourable to the institution. The existing Theories and Tables of the Moon are founded entirely upon the Greenwich Observations; the Observatory of Greenwich has been looked to as that from which alone adequate observations can be expected, and from which they will not be expected in vain: and it is not perhaps venturing too much to predict that, unless some gross dereliction of duty by the managers of the Observatory should occur, the Lunar Tables will always be founded on Greenwich Observations. With this impression it has long been to me a matter of consideration whether means should not be taken for rendering the series of Observations of the Moon more complete than it can be made by the means at present recognized in our observatories."--In illustration of the foregoing remarks, the original inscription still remaining on the outside of the wall of the Octagon Room of the Observatory may be quoted. It runs thus: 'Carolus II's Rex Optimus Astronomiae et Nauticae Artis Patronus Maximus Speculam hanc in utriusque commodum fecit Anno D'ni MDCLXXVI Regni sui XXVIII curante Iona Moore milite RTSG.'
"The Ashburton Treaty had been settled with the United States, for the boundary between Canada and the State of Maine, and one of its conditions was, that a straight line about 65 miles in length should be drawn through dense woods, connecting definite points. It soon appeared that this could scarcely be done except by astronomical operations. Lord Canning, Under Secretary of the Foreign Office, requested me to nominate two astronomers to undertake the work. I strongly recommended that Military Officers should carry out the work, and Capt. Robinson and Lieut. Pipon were detached for this service. On Mar. 1st they took lodgings at Greenwich, and worked at the Observatory every day and night through the month. My detailed astronomical instructions to them were drawn out on Mar. 29th. I prepared all the necessary skeleton forms, &c., and looked to their scientific equipment in every way. The result will be given in 1844.
"Of private history: In January I went to Dover with my wife to see the blasting of a cliff there: we also visited Sir J. Herschel at Hawkhurst. In April I was at Playford, on a visit to Arthur Biddell. On Apr. 9th my daughter Annot was born. From July 22nd to August 25th I was travelling in the South of Ireland, chiefly to see Valencia and consider the question of determining its longitude: during this journey I visited Lord Rosse at Birr Castle, and returned to Weymouth, where my family were staying at the time. In October I visited Cambridge, and in December I was again at Playford."
The journey to Cambridge (Oct. 24th to 27th) was apparently in order to be present on the occasion of the Queen's visit there on the 25th: the following letter relating to it was written to his wife:
SEDGWICK'S ROOMS,
TRINITY COLLEGE, CAMBRIDGE.
1843, Oct. 26, Thursday .
I have this morning received your letter: I had no time to write yesterday. There are more things to tell of than I can possibly remember. The Dean of Ely yesterday was in a most ludicrous state of misery because his servant had sent his portmanteau (containing his scarlet academicals as well as everything else) to London, and it went to Watford before it was recovered: but he got it in time to shew himself to-day. Yesterday morning I came early to breakfast with Sedgwick. Then I walked about the streets to look at the flags. Cambridge never had such an appearance before. In looking along Trinity Street or Trumpington Street there were arches and flags as close as they could stand, and a cord stretched from King's Entrance to Mr Deck's or the next house with flags on all its length: a flag on St Mary's, and a huge royal standard ready to hoist on Trinity Gateway: laurels without end. I applied at the Registrar's office for a ticket which was to admit me to Trinity Court, the Senate House, &c., and received from Peacock one for King's Chapel. Then there was an infinity of standing about, and very much I was fatigued, till I got some luncheon at Blakesley's rooms at 1 o'clock. This was necessary because there was to be no dinner in hall on account of the Address presentation. The Queen was expected at 2, and arrived about 10 minutes after 2. When she drove up to Trinity Gate, the Vice-Chancellor, masters, and beadles went to meet her, and the beadles laid down their staves, which she desired them to take again. Then she came towards the Lodge as far as the Sundial, where Whewell as master took the college keys (a bundle of rusty keys tied together by a particularly greasy strap) from the bursar Martin, and handed them to the Queen, who returned them. Then she drove round by the turret-corner of the court to the Lodge door. Almost every member of the University was in the court, and there was a great hurraing except when the ceremonies were going forward. Presently the Queen appeared at a window and bowed, and was loudly cheered. Then notice was given that the Queen and Prince would receive the Addresses of the University in Trinity hall, and a procession was formed, in which I had a good place, as I claimed rank with the Professors. A throne and canopy were erected at the top of the hall, but the Queen did not sit, which was her own determination, because if she had sat it would have been proper that everybody should back out before presenting the Address to the Prince: which operation would have suffocated at least 100 people. The Queen wore a blue gown and a brown shawl with an immense quantity of gold embroidery, and a bonnet. Then it was known that the Queen was going to service at King's Chapel at half past three: so everybody went there. I saw the
