Seeing Further: The Story of Science and the Royal Society. Bill Bryson

had to wait till the twentieth century.) But interest in Tenerife did not abate – far from it. Curiosity about remote lands was always honoured in Royal Society discourse. ‘It was directed,’ according to the minutes for 25 March, ‘that inquiry should be made, whether there be such little dwarvish men in the vaults of the Canaries, as was reported.’ And at the next meeting, ‘It was ordered to inquire, whether the flakes of snow are bigger or less in Teneriffe than in England…’

      Reports did arrive from all over. The inaugural issue of the Philosophical Transactions featured a report (written by Boyle, at second hand) of ‘a very odd Monstrous Calf’ born in Hampshire; another ‘of a peculiar Lead-Ore of Germany’; and another of ‘an Hungarian Bolus’, a sort of clay said to have good effects in physick. From Leyden came news of a man who, by stargazing nightly in the cold, wet air, obstructed the pores of his skin, ‘which appeared hence, because that the shirt, he had worn five or six weeks, was then as white as if he had worn it but one day’. The same correspondent described a young maid, about thirteen years old, who ate salt ‘as other children doe Sugar: whence she was so dried up, and grown so stiff, that she could not stirre her limbs, and was thereby starved to death’.

      Iceland was the source of especially strange rumours: holes, ‘which, if a stone be thrown into them, throw it back again’; fire in the sea, and smoking lakes, and green flames appearing on hillsides; a lake near the middle of the isle ‘that kills the birds, that fly over it’; and inhabitants that sell winds and converse with spirits. It was ordered that inquiries be sent regarding all these, as well as ‘what is said there concerning raining mice’.

      The very existence of these published transactions encouraged witnesses to relay the noteworthy and strange, and who could say what was strange and what was normal? Correspondents were moved to share their ‘Observables’. Observables upon a monstrous head. Observables in the body of the Earl of Balcarres (his liver very big; the spleen big also). Observables were as ephemeral as vapour in this camera-less world, and the Society’s role was to grant them persistence. Many letters were titled simply, ‘An Account of a remarkable [object, event, appearance]’: a remarkable meteor, fossil, halo; monument unearthed, marine insect captured, ice shower endured; Aurora Borealis, Imperfection of Sight, Darkness at Detroit; appearance in the Moon, agitation of the sea; and a host of remarkable cures. An Account of a remarkable Fish began, ‘I herewith take the liberty of sending you a drawing of a very uncommon kind of fish which was lately caught in King-Road…’

      It fought violently against the fisher-man’s boat…and was killed with great difficulty. No body here can tell what fish it is…I took the drawing on the spot, and do wish I had had my Indian Ink and Pencils…

      From Scotland came a careful report by Robert Moray of unusual tides in the Western Isles. Moray, a confidant of the King and an earnest early member of the Society, had spent some time in a tract of islands for which he had no name – ‘called by the Inhabitants, the Long-Island’ (the Outer Hebrides, we would say now). ‘I observed a very strange Reciprocation of the Flux and Re-flux of the Sea,’ he wrote, ‘and heard of another, no less remarkable.’ He described them in painstaking detail: the number of days before the full and quarter moons; the current running sometimes eastward but other times westward; flowing from 9½ of the clock to 3½ ebbing and flowing orderly for some days, but then making ‘constantly a great and singular variation’. Tides were a Royal Society favourite, and they were a problem. Humanity had been watching them for uncounted thousands of years, and observing the coincidence of their timing with the phases of the Moon, without developing an understanding of their nature – Descartes notwithstanding. No global sense of the tides could be possible when all recorded information was local. And even now, Moray emphasised the peculiarity of his observations; and quailed at the idea of generalising.

      To penetrate into the Causes of these strange Reciprocations of the Tides, would require exact descriptions of the Situation, Shape, and Extent of every piece of the adjacent Coasts of Eust and Herris; the Rocks, Sands, Shelves, Promontorys, Bays, Lakes, Depths, and other Circumstances, which I cannot now set down with any certainty, or accurateness; seeing, they are to be found in no Map.

      He had drawn a map himself some years earlier, but it was gone. ‘Not having copied [it], I cannot adventure to beat it out again.’

      As often as they could be arranged, experiments were performed for the assembled virtuosi. Brouncker prosecuted his experiment of the recoiling of guns, Wren his experiment of the pendulum, William Croone his experiment with bladders and water. When Robert Hooke took charge of experiments, they came with some regularity. Even so, many more experiments were described, or wished for, than were carried out at meetings. The grist of the meetings was discourse – animated and edifying. They loved to talk, these men.

      They talked about ‘magnetical cures’ and ‘sympathetical cures’ and the possibility of ‘tormenting a man with the sympathetic powder’. They talked about spontaneous equivocal generation: ‘whether all animals, as well vermin and insects as others, are produced by certain seminal principles, determined to bring forth such and no other kinds. Some of the members conceived, that where the animal itself does not immediately furnish the seed, there may be such seeds, or something analogous to them, dispersed through the air, and conveyed to such matter as is fit and disposed to ferment with it, for the production of this or that kind of animal.’ They talked about minerals discovered under ground, in ‘veins’, wondering whether they grew there or had existed since the creation. Some suggested that metals and stones were produced ‘by certain subterraneous juices…passing through the veins of the earth’.

      They talked about why it was hotter in summer than in winter; no one knew, but George Ent had a theory. It was ordered to be registered in a ‘book of theories, which was directed to be provided’. George Villiers, the Duke of Buckingham, newly admitted to the Society, produced what he promised was the horn of a unicorn. Legend had it that a circle drawn with such a thing would keep a spider trapped until it died, so they performed the experiment: ‘A circle was made with powder of unicorn’s horn, and a spider set in the middle of it, but it immediately ran out. The trial being repeated several times, the spider once made some stay on the powder.’

      Still, the discourse was liberating. ‘Their first purpose,’ said Thomas Sprat, writing his ‘history’ of the Society when it was barely fledged, ‘was no more, than onely the satisfaction of breathing a freer air, and of conversing in quiet one with another, without being ingag’d in the passions, and madness of that dismal Age’. The rules were clear: nothing about God; nothing about politics; nothing about ‘News (other than what concern’d our business of Philosophy)’. And what news was that? John Wallis specified, ‘as Physick, Anatomy, Geometry, Astronomy, Navigation, Statics, Mechanics, and Natural Experiments’.

      James Long, newly admitted in April 1663, delivered the news, as the amanuensis reported in his minutes, ‘that there were ermines in England’. He promised to produce some. ‘He mentioned also, that bay-salt being thrown upon toads would kill them…he made mention likewise of a kind of stones with natural screws, and promised to show some of them.’

      At the next meeting, Long talked about the generation of ants: they come out of pods full of eggs. He added that he had seen a maggot under a stag’s tongue; that land-newts are more noxious than water newts; and that toads become venomous in hot weather and in hot countries such as Italy. Croone mentioned that he had seen a viper with a young one in its belly, and Long added, ‘The female viper hath four teeth, two above and two below; but the male only two and those above.’ Hooke showed some new drawings he had made from observations with his microscope, including a spider with six eyes – lately he had been bringing something new to almost every meeting. Moray described a watch with particularly hard steel, which reminded Long that he had once seen a breast-piece so tough that a pistol bullet only dented it.

      Long was a military man, having been first a captain and then colonel of horse in a Royalist regiment. John Aubrey describes him as a good swordsman and horseman and a devotee of ‘astrology, witchcraft and natural magic’. He does seem to have found him rather voluble – ‘an admirable extempore orator for a harangue’. They went hawking together, and what Aubrey recalled was that Long never stopped
