It is, perhaps, scarcely necessary to add, that all the suggestions attributed to Brewster and Herschel, in the beginning of the article, about "a transfusion of artificial light through the focal object of vision," etc., etc., belong to that species of figurative writing which comes, most properly, under the denomination of rigmarole.
Estimating this, not with reference to the zero of our thermometers, but with reference to the temperature of the celestial spaces, Sir John Herschel calculates "23° Fahrenheit, as the least variation of temperature under such circumstances which can reasonably be attributed to the actual variation of the sun's distance."
But already this supposed continuity was broken. After mature deliberation on the phenomena presented by nebulous stars, Herschel was induced, in 1791, to modify essentially his original opinion.
The catalogue which he then contributed to the "Philosophical Transactions" includes 2306 nebulae and star-clusters, of which 525 were discovered by himself. While engaged in this difficult task, Herschel discovered between three and four thousand double stars, which he described in the Memoirs of the Astronomical Society.
It was in the companionship of these remarkable persons, and under the shadow of his father's wonderful telescope, that John Herschel passed his boyish years.
Long after, it is said, when Herschel had distinguished himself by the discovery of the planet Uranus, a pardon for this high military offence was duly handed to him by the king in person on the occasion of his first presentation.
And what would become of Fanny and of little Josephine if they were brought up under the demoralizing influences of spectacles like that! Do you suppose I 'm going to have Galileo and Herschel corrupted? And little Erasmus shall his pure, innocent mind be contaminated? Never, neighbor Robbins, never!" But Mr. Robbins did not seem to view the matter at all as I did.
Many remained, and of that number two skeletons were afterwards found, and on board one of the ships the "bones of a large man with long teeth!" That is all! The remainder pushed on to Cape Herschel, and left a record in a cairn.
So distant from our universe are these now universes of Herschel's discovery that their light reaches us only as a dim, nebulous glow, in most cases invisible to the unaided eye. About a hundred of these nebulae were known when Herschel began his studies.
But what did Herschel learn regarding these awful depths of space and the stars that people them? That was what the world wished to know. Copernicus, Galileo, Kepler, had given us a solar system, but the stars had been a mystery.
