 science, and the constructing of telescopes, and observations of the heavens, continued to form the occupations of the remainder of his life.

Astronomy is indebted to him for many more most interesting discoveries besides the celebrated one of which we have just given an account, as well as for a variety of speculations of the most ingenious, original, and profound character. But of these we cannot here attempt any detail.

He also introduced some important improvements into the construction of the reflecting telescope, besides continuing to fabricate that instrument of dimensions greatly exceeding any that he had formerly attempted, with powers surpassing, in nearly a corresponding degree, what had ever been before obtained. The largest telescope which he had ever made was his famous one of forty feet long, which he erected at Slough, for the king.

It was begun about the end of the year 1785, and on the 28th of August 1789 the enormous tube was poised on the complicated but ingeniously-contrived mechanism by which its movements were to be regulated, and ready for use. On the same day a new satellite of Saturn was detected by it, being the sixth that had been observed attendant on that planet. A seventh was afterward discovered, by means of the same instrument. This telescope has since been taken down, and replaced by another of only half the length, constructed by the distinguished son of the subject of our present sketch.

So extraordinary was the ardor of this great astronomer in the study of his favorite science, that for many years, it has been asserted, he never was in bed at any hour during which the stars were visible, and he made almost all his observations, whatever the season of the year, not under cover, but in his garden, in the open air—and generally without an attendant. By these investigations Herschel became acquainted with the character of the more distant stars, upon which he wrote a variety of papers. In 1802, he presented to the Royal Society a catalogue of five thousand new nebulæ, nebulous stars, planetary nebulæ, and clusters of stars; thus opening up a boundless field of research, and making the world aware of the sublime truth of there being an infinitude of heavenly bodies far beyond the reach of ordinary vision, and performing in their appointed places the offices of suns to unseen systems of planets.

These discoveries established Herschel's claims to rank amongst the most eminent astronomers of the age, and amply merited the distinctions conferred upon him by learned bodies and the reigning prince. In 1816, George IV, then prince regent, invested him with the Hanoverian and Guelphic order of knighthood. He was now, from being originally a poor lad in a regimental band, rewarded for his long course of honorable exertion in the cause of science. Herschel (now Sir William) did not relinquish his astronomical observations until within a few years of his death, which took place on the 23d of August, 1822, when he had attained the age of eighty-three. He died full of years and honors, bequeathing a large fortune, and leaving a family which has inherited his genius.

The Spanish colonies of South America remained for three centuries in quiet submission to the mother country, if we except the desperate attempt of the Peruvian Indians, under Tupac Amaru, to throw off the yoke of
