THE ROYAL SOCIETY OF LONDON. If I were to attempt to do justice to the merits of this great society, I should have to devote many pages, to such subjects as the achromatic telescope of Dollond; the dividing engine of Ramsden, which first gave precision to astronomical observations, the measurement of a degree on the earth's surface by Mason and Dixon; the expeditions of Cook in connection with the transit of Venus; his circumnavigation of the earth; his proof that scurvy, the curse of long sea-voyages, may be avoided by the use of vegetable substances; the polar expeditions; the determination of the density of the earth by Maskelyne's experiments at Scheliallion, and by those of Cavendish; the discovery of the planet Uranus by Herschel; the composition of water by Cavendish and Watt; the determination of the difference of longitude between London and Paris; the invention of the voltaic pile; the surveys of the heavens by the Herschels; the development of the principle of interference by Young, and his establishment of the undulatory theory of light; the ventilation of jails and other buildings; the introduction of gas for city illumination; the ascertainment of the length of the seconds-pendulum; the measurement of the variations of gravity in different latitudes; the operations to ascertain the curvature of the earth; the polar expedition of Ross; the invention of the safety-lamp by Davy, and his decomposition of the alkalies and earths; the electro-magnetic discoveries of Oersted and Faraday; the calculating-engines of Babbage; the measures taken at the instance of Humboldt for the establishment of many magnetic observatories; the verification of contemporaneous magnetic disturbances over the earth's surface.
You don't know Mrs. Dollond?" he added, seeing that the other looked at him with a certain air of wistful distrust, a momentarily visible desire to see behind so obvious a veil. "No, thank God!" said Oswyn devoutly, shrugging his bent shoulders, and turning away with a relapse into his unwonted impassiveness. "But you have apparently heard of her," continued Rainham, with an effort toward humour.
A few minutes before the appointed hour he made his way, from the new and alarmingly revolutionary club-house, where he had been indulging in afternoon tea in company with Felicia Dollond, to the gallery, outside which his horses were already waiting, and, perceiving Oswyn's name on the placards disposed on either side of the entrance, he felt only a momentary hesitation.
He supposed that refraction and chromatic dispersion went hand in hand, and that you could not abolish the one without at the same time abolishing the other. Here Dollond corrected him. But Newton committed a graver error than this. Science, as I sought to make clear to you in our second lecture, is only in part a thing of the senses.
When the music had ceased, and the measured tread of feet lapsed into the confusion of independent wanderings, Eve turned to find her husband close behind her, and Mrs. Dollond firing off a neat little speech of congratulation, panting a little, and making play with her elaborate fan.
Dollond had so much admired. "I hope they won't notice Cesare's pipe," he said anxiously. "Even though he doesn't smoke here, it always seems to hang about. Perhaps I had better open the window and burn a pastille. And now, are we prepared to receive Philistia? Yes, I don't think the place looks bad, and but perhaps Mrs. Sylvester mightn't like the gladiator.
Dollond, "your wife is planning some delightful surprise for us: I can see it in her eyes! Though, what one could want more " The music began again, and the couples took their places for the Lancers: there was to be a Shakespearian set, and another of Waverley notabilities.
He had barely had time to arrange the borrowed tea-things, and to set a kettle on a little spirit-lamp behind the screen, when Mrs. Dollond and her husband were announced. He threw his black sombrero somewhat theatrically into a corner, and advanced with effusion to meet them. Mrs.
In the time of Dollond it was found scarcely possible to make good disks of flint-glass more than three or four inches in diameter. Early in the present century, Guinand, of Switzerland, invented a process by which disks of much larger size could be produced.
The same result was thus produced of necessity, in the eye, that Dollond came at, in the telescope, with design, through painful guessing, reasoning, experimenting, and forming. Suppose our skeptic to believe in all this power of natural selection; will he now seal up his verdict for design, with the same confidence that he would before he heard of Darwin?
