Funchal, April 6

My very dear Mother

I think that our time here is nearly up. We are to go on by the steamer Portugal which is due here on Wednesday, April 9, and should reach Principe on the 23rd. It calls at two places in the Cape Verde Islands and then goes straight to Principe. We shall not be the only English on board as we know of two others going as far as St Vincent (in Cape Verde Is.). The Quelimane which we had thought at first would be our boat was due here on the 3rd but did not arrive till yesterday; it was going direct to St Thomé, only a hundred miles from Principe, but did not call at Principe.

Since my last letter I have had one other splendid walk on the hills. I went alone as it was too far for Cottingham. I started at 7∙45 and reached Terreira de Lucta (the terminus of the railway) by half past nine; I was walking as there was no train early enough. It was then an easier walk though still uphill over Poiso pass 4550 feet up; then steep downhill to Ribiera Frio. This is one of the famous view-points of the island. The Balçoã (or balcony) there is about 2800 feet above sea-level, and one looks up and down a splendid deep ravine, thickly wooded. It is the same ravine that I saw from Ariero Observatory; but here, being in the middle of it instead of at one end, one gets a much better view and better idea of its size and depth. I reached this place about 12∙15 and stayed there till near 2 o’clock. It was very fortunate I had made an early start, because by the time I left the mist had come up from the sea on the north of the island and completely filled the ravine, so that one could see nothing. When I got there it was quite clear except for a few clouds round two or three of the highest snow-covered peaks. The highest peaks are 6000 feet high. One got good views of the levadas (artificial aqueducts) cut in the sides of the precipitous cliffs, and part of the way the path was by the side of one of these levadas. I climbed back through the mist to Poiso; and then got into the sunshine again, and left the road striking over the hills to Pico da Silva more to the east, getting a good view of the coast at the east end of the island. I reached Funchal about 6∙30, coming down the last 2000 feet by a very steep road like a flight of steps. The walk was about 25 miles altogether.

A good many of the people staying at this hotel left by a boat last Sunday, and it seems more empty now. There are about 8 or 10 permanent residents, and in addition I think there are only three other visitors—Ash (an old gentleman who came with us on the Anselm), Mr Bickmore a new arrival, and Geoffrey Turner a boy of sixteen from Mumbles, who has come out here for six weeks after an illness. Since some of his fellow-passengers left last Sunday, he has come to sit at our table and generally goes about with us.

The weather this last week has been very showery but always with long intervals of bright sunshine. The inhabitants say it is exceptionally bad weather; but I only wish we had “bad weather” of this kind in England. It is, however, unsuitable for long walks and the clouds are fairly low on the mountains; but that does not matter as I have been to the chief points of interest that are at all accessible. Nearly every morning this last week I have spent bathing at the Ajuda a place on the coast rather more than a mile from here which Geoffrey showed us. It is about the only place for a bathe here unless one goes out in a boat. The sea is rather rough and the coast rocky; but here there is a more or less enclosed pool where one can get a good swim without being knocked about on the rocks by the waves. I have got tremendously sunburnt.

We generally go to the Casino for tea, though we have tried once or twice another restaurant. There is always a band there. Roulette is prohibited in Madeira; but the authorities pretend not to know that it goes on. Now and again they make a raid, but they always telephone up to say they are coming. One afternoon, I was wanting to come away and found the main doors, which lead out through the dancing saloon, fastened, and we had to come out by a back way; the reason was that the Chief of the Police had come up for the dancing, and he was supposed not to know what was going on the other side of the door.

I have scarcely ever been out after dinner, but last night I went with Geoffrey to a picture-palace. The chief film was the funeral of King Edward VII! It was rather curious seeing it after so many years. After about ¾ hour of pictures, there was a short play of which we naturally could understand nothing. Then some recitations (chiefly serious) and some songs (chiefly comic). One of the comic songs was very amusing though one could not understand the words. It was a very crowded house, and very interesting to watch the audience.

I had a talk this morning with the English Doctor an old gentleman who has gone in for science a good deal. He is brother-in-law to the late Lord Kelvin, and told me a lot of stories about him. Kelvin met his wife at Madeira—a Miss Blandy—the Blandys are the agents of most of the shipping companies here, and they saw after storing our instruments, here.

I expect my next letter will be from Cape Verde Islands. I shall be glad to be progressing again; but I have enjoyed the whole of my stay here immensely—it has been a splendid holiday

With very dear love from
your loving son
Stanley

Barskimming, Maughline, Ayrshire. Private - Asks if he would accept the Gifford Lectureship [at Glasgow University] for the years 1898-1900 if it were offered to him; he would like an answer that evening in advance of a meeting with Lord Kelvin.

Pitlochry, Perthshire - Has WW seen in the Philosophical Magazine for July, August and September a controversy involving John Tyndall and James Joule over 'a question of priority, much resembling Tyndall's advocacy of Rendu at my expense?' The dispute centres on the ''Dynamical theory of heat' or the 'convertibility of force' and the meteonic theory of the sun's heat'. Tyndall gives the credit of these theories to 'an unknown German physician named Mayer'. William Thomson and Joule 'are treated a good deal in the way I was'. Both have written replies, Joule in the Philosophical Magazine and Thomson in the Glasgow periodical called 'Good Words'. JDF gives a long quote from Thomson's piece.

Edinburgh - JDF has 'frittered away' the summer and has now returned to St. Andrew's for the winter. He read 'Arago's posthumous writings on Photometry and I do not think highly of them'. His chief reason for writing 'is to ask whether I can find anywhere in print the formalities used in your University' ceremonies. He was not at the BAAS meeting at Manchester: 'It seems to have been organized on too gigantic a scale'. George Airy's lecture on the ecliptic was presumably the 'chief novelty: but so far as one can judge from abstracts the results are just what we already knew'. William Hopkins '(who is now to be general secretary) could not let glacier theories alone; but has carefully abstained from printing forth any abstract'. JDF 'visited William Thomson at his place in Arran. He is still fearfullly lame'.

Pitlochry - JDF thanks WW for sending the minutes of the Council of the Royal Society: 'I am deeply gratified by your kind exertions to obtain for me a recognition of my labours which I had long ceased to expect'. Lady Affleck must not think JDF has 'forgotten my promise about her brother' [JDF wrote an obituary of Robert L. Ellis]: 'William Thomson has given me a few notes on his mathematical qualities of mind, which is the only other assistance I have sought'. JDF returns the printed minutes of the council, and 'was exceedingly gratified that Prof. Miller seconded my nomination. It was the more flattering because his friend Weber was in the field'. He is pleased that Clerk Maxwell is proposed for a Royal Medal for his 'masterly paper on colour'.

Edinburgh - The Forbes family have pleasant memories of WW and Lady Affleck's recent visit - 'which I sincerely hope may be repeated'. JDF has read WW's review of Bacon with interest since you told me where to find it. Mr Spedding's publication now assumes a formidable magnitude' ['Review of Spedding and Ellis's edition of Francis Bacon', 1857]. JDF has just had a letter from William Thomson 'asking me to be present at a public dinner to be given to him in Glasgow in connection with the Atlantic Telegraph. That, as you know is not in my line. And while cordially rejoicing in our excellent friends distinction, I cannot help severely regretting that he has mixed himself up so much with the commercial branch of the affair - which besides is far from prosperous. He is not only a Director but a Patentee in connection with it'.

Glasgow - WT feels 'very strongly inclined towards Faraday's view that the substance of a diamagnetic is polar like oxygen or iron, when near a magnet, but that it is less so than the surrounding medium'. John Tyndall 'is in error if he still supposes that either his experiments or Weber's, or any others yet made affords a test as to whether this hypothesis, or true hypothesis that bismuth and the like, have a polarity the reverse of that of iron in the same circumstances. The resultant external force between a diagmagnet and paramagnet is demonstrably the same which ever hypothesis is true; and those experiments are solely indicative of resultant external force' [see WT to James Forbes, 19 March 1857]. Perhaps Faraday doubted Weber's [Wilhelm Weber] experiment gave any other result and he certainly doubted the truth of the interpretation put on Weber's results. 'Tyndall's repetition of Weber's experiment I believe convinced Faraday that the result was genuine'. WT has written a short article in the Cambridge and Dublin Mathematical Journal in May 1846, which 'contains principles and mathematical expressions, founded solely on what Faraday told me in his first paper, which lead in the most obvious way to the determination of all such forces as those which Weber and Tyndall observed'. WT describes what a (mechanical) explanation of electromagnetic induction would entail. Regarding 'Ampere's [André Ampere] theory of real motions in minute circular orbits or vortices, with axes on the whole set in the directions of the line of force, to account for magnetism, I think it is probably true. The magnetic optic discovery seems explicable on no other hypothesis. Since Foucault's [Jean Foucault] exhibition at Liverpool I have been much disposed to look on the gyroscope as an illustration of a magnet. It is of course difficult to see how a current ([?] of matter flowing) through a straight wire can induce among the thermal motions in the surrounding medium, eddies of which the axes are circles in planes perpendicular to the wire; and how eddies in a steel bar magnet with their axes on the whole parallel to its length can induce among the surrounding thermal motions, eddies rooted to the steel at each end...Still it is not beyond expectation that a definite mechanical explanation of such influences may be invented'. If this is done it simply shows that magnetic attraction is a product of pressure along the axes of eddies, caused by centrifugal force. An 'explanation of electromagnetic induction would have to be looked for by considering mechanically the effects produced by moving as whole, pieces of matter among the particles of which these are vortical motions with determined sets'. WT does 'not see how a momentary recoil in the surrounding matter can account for electromagnetic induction'. Nevertheless 'there may be lateral action at or near the boundaries of the conductor in its interior with a reaction causing the external induced current'. WT thinks 'Faraday must be right in supposing both electric action to be conducted through matter and by means of the matter through which it is conducted'. 'Is it credible that matter can act where it is not? Were not those of the schoolmen who demonstrated a universal Plenum right?' WT wonders whether WW can come up with any epithets for recent developments in electrostatics: 'I would like to be able to distinguish between systems in which the electricity to be tested is tried by one, and by two, independently electrified bodies'. He would also like names to distinguish electrometers.

Glasgow - WT [later Lord Kelvin] attended Michael Faraday's lecture on Gravitation, and spoke to both him and John Tyndall: 'I made a slight attack on Tyndall by asking him to explain to me the distinction between a viscous solid and a plastic solid. He said that before the end of a year it would be very clear. Which ever word is the most appropriate is the best expression of your theory as I have always understood it. As to the clear and porous alternate layers proving the veined structure, I do not know whether you lay much stress on the explanation Tyndall quotes as yours. It may be true what Tyndall says - that it is occasioned by pressure but that is no explanation'. Many writers have assumed that pressure is the cause of the clearage in slate mountains: 'It is a real thing proved if Tyndall or any one else can prove the clearage surfaces to be perpendicular to the lines of maximum compression'. In diamagnetics WT holds that Weber [Wilhelm Weber] and Tyndall have illustrated by experiment conclusions deducible (and which I deduced in 1846) from Faraday's forces experienced by bismuth; that they have established no new conclusion'. Faraday does not seem to perceive the relation with Weber's phenomena and even doubts Weber's results; 'Tyndall's repetition of Weber's experiment (described in the Phil. Trans.) confirmed the results and removed the possibility of such doubts as Faraday had temporarily raised. Not one of these experiments touches the ultimate nature of the magnetic effect experienced by the substance of a piece of bismuth, since the resultant external action is necessaily the same whether air in the surrounding medium is unpolarised and bismuth severly, or the surrounding medium and the substance of the bismuth both polarised directly (like a 'paramagnetic') but the surrounding medium more so than the bismuth'. Many of Tyndall's experiments simply prove things that did not require proving: 'In reality no testing experiment has ever been made to distinguish between two hypothesis: and I agree (I believe) with Faraday in thinking the second the more probable of the two true (I had a good deal of this in a letter to Tyndall which he published in the Phil. Mag. April 1855)'. WT has been occupied chiefly with electrometers and electroscopes in the apparatus room.

Manchester - WT [later Lord Kelvin] encloses a 'statement of objects of research on the thermal effects of fluids in motion, and an account of expenditure by Mr Joule [James Joule] and myself'. The investigations are described in a paper communicated to the Royal Society last June and now printed. He hopes to communicate another one in a few weeks.

JDF encloses a letter he received from William Thomson [not present], in which he answers a question JDF put to him regarding 'Faraday's and Tyndall's views of the polarity of Bismuth. For myself I can attach no meaning to the magnetic of space per se' [John Tyndall. On the Existence of a Magnetic Medium in Space, 1855].

Edinburgh - Thanks WW for the tidal papers. JDF thinks of the mechanical theory of heat 'pretty much as you do. I intended to speak of it with great caution, and it seems to me that I have done so. I believe that there is a basis of fact for it or for part of it'. JDF expects that 'Thomson [William Thomson] and his friends' will be annoyed that he did not give Joule [James Prescott Joule] a section to himself: 'Thomson (admirer as he is of Faraday) would certainly not allow to see [Faraday] superior to Joule, about whom he is, to my conception, scarcely rational'. Has WW sent his suggestions to the Parliamentary Committee of the BAAS about promotion of science by the state?: 'I have recommended (selfishly no doubt) the endowing of existing professorships of science; but (not selfishly) that they should begin with those of Cambridge and Oxford'.
