2 Brook Street - HH is extremely glad WW is to publicly support John Couch Adams's claim to have discovered the new planet [Neptune] - as opposed to Urbain Jean Le Verrier: 'It is clear to me after reading the three papers produced at the astronomical society, that Adams would be precisely where Leverrier's now is, had the observations early in August ripened into actual discovery of the nature of the body, actually seen then by the guidance of Adam's calculations. Arago [Francois Arago] is moving heaven and earth (the phrase is not inappropriate here) to fix Leverrier's name upon it'. The planet's name should be taken from mythology.

7 Camden St. & T. - The spoon is a good representation of inductive logic. Whewell's notion of induction contains more than logic. Spoon feeding is synthetical (induction) and knife and fork feeding is analytical. Whewell will probably see a scene at the Astronomical Society as Jerwood, who accused Airy and Le Verrier of conspiring to defraud Adams [regarding the discovery of Neptune], has been proposed as a fellow. He describes his friend [Joshua Ryland] Marshman's suitability for the Professorship of Law at Cambridge.

Thanks WW for his kind letter and hopes he really can do something for him [one of the candidates for the Professorship at St. Andrews in Natural Philosophy]. The evidence [for the discovery of Neptune] is decisively in favour of John Couch Adams.

Edinburgh - JDF is interested in what WW has to say regarding Barrow [Barrow and his Academical Times, 1859]. He is sorry to hear of Robert L. Ellis's very ill state. Is it true that Adams [Couch Adams] has accepted the mathematical chair at St. Andrews? There is endless talk on the improvement of the British universities and JDF thinks they 'may be materially improved; but the misfortune is that those who combine to make a clamour have few ideas in the least in common...I do not think however that the worst of us would do anything more ridiculous than Oxford has done with her associates'. Can WW advise him what to do regarding John Tyndall's 'papers which profess to rectify my theories about glaciers. I am not disposed now-a-days to enter into controversy if I can help it...and there is an especial difficulty in this case that Tyndall has gradually paved away so much of what was definitely controvertible in his earlier papers that one does not know where to hold him, the differences become so fine'. JDF would not therefore worry, but 'On the other hand I have been informed that he makes a considerable impression in London and that his repeated returns to the subject, and my silence, create an impression that he has obtained a victory'. Could WW find out what the prevalent opinion is?.

Royal Observatory Greenwich - Sheepshanks Exhibition [see GA to WW, 30 Sept. 1856] can be divided into three parts: 1. Gravitational, 2. Geometrical Astronomy and 3. Theory and Practice of Observations. GA could do number 3, Mathison [William C. Mathison] number 2 and if Adams [John C. Adams] is around, he could do number 1. A Transit-Circle was first introduced in Greenwich, because 'a Mural Circle cannot carry a large object-glass. - But there are many distinct advantages. As a Transit, it is no better than a detached Transit, but as a Circle it holds its position much better than a Mural Circle: the same object is infallibly observed in both elements; and (probably for that reason) one observer with the Transit-Circle observes a greater number of objects than two with Transit and Mural Circle: and it saves the salary of one observer'.

Royal Observatory Greenwich - Further to Miss Sheepshanks supplementary grant of £2000 plus [see GA to WW, 15 Nov. 1860], John C. Adams 'considers that his status would be improved by having - a Transit Circle - a Chronographic Galvanic Apparatus - a system of sympathetic clocks - and a Telegraphic communication with the long lines of Telegraph. So I begged him to speak with you...I think the purposes suggested by Adams are all very good'.

Royal Observatory Greenwich - John C. Adams would be happy 'to have the present from Miss Sheepshanks communicated to the Observatory Syndicate' [see GA to WW, 13 Feb. 1862]. GA has drawn up the letter and if WW approve it, he should hand it to Adams.

Royal Observatory Greenwich - GA understands that the Prince and Princess of Wales will be visiting Cambridge on the same day of the Visitation of the Royal Observatory. Presumably this means WW, James Challis, John C. Adams and George Stokes will not be able to attend, making the meeting a 'rather a lame one'.

Encloses Rayleigh's letter [not included]. Wishes that the latter had asked him to bring Myers to Terling, and suggests that he may yet do so. Claims that Mrs Jencken 'seems about the best medium out, and to have her rapping away in the private house of a senior wrangler using all the resources of his laboratory is too tempting a prospect.' Proposes to ask Rayleigh to arrange for some séances with Mrs Jencken in London, to which Myers could bring [John Couch?] Adams. Asks Myers if he could alter the time of his inspectorial visit, in case Rayleigh wishes to confine his invitation to Sidgwick. Reports that their 'anxiety still goes on: but the doctors seem to have good hopes.'

Collingwood - JH gives his reasons why WW should not, as has been reported, pledge such a strong declaration of support for John C Adams's and the 'discovery' of Neptune over [Urbain J. J.] Le Verrier: If the results of the latter had not 'appeared I think it by no means improbable that Challis might actually never have turned a telescope to the heavens in search of it at all'.

Royal Observatory Greenwich - Adams [John C. Adams?] has invited GA to the Johnian dinner on Monday. Due to a long standing agreement GA has written to Sedgwick [Adam Sedgwick] to dine with him on the Tuesday, hence he has not put in an application for WW's hospitality.
