He called yesterday and asked me to dine with him to-day. He has a charming place, about four miles out of Liverpool; a pretty house and grounds. "Mr. Lassell has constructed two telescopes, both on the Newtonian plan; one of ten, the other of twenty, feet in length. Each has its separate building, and in the smaller building is a transit instrument. "Mr.
Herschel, Faraday, Robinson, Taylor, Phillips, Brewster, Rosse, Fairbairn, Lassell, and a host of minor stars, who, although perhaps wanting in the brightness or magnitude of those I have named, made good amends by the warmth of their cheerful rays. We saw the younger lights emerging above the horizon: the men who still continue to shed their glory over the meetings of the Association.
As only two of these had been seen again, while two more were discovered by Lassell, the inference was that Uranus has eight satellites in all. These for a long time flourished in our text-books of astronomy; and many writers, confident in the care and skill of Sir W. Herschel, were unable for a long time to believe that he had been deceived.
Within seventeen days of its identification with the Berlin achromatic, Neptune was found to be attended by a satellite. This discovery was the first notable performance of the celebrated two-foot reflector erected by Mr. Lassell at his suggestively named residence of Starfield, near Liverpool. William Lassell was a brewer by profession, but by inclination an astronomer.
Where a ridge suddenly changes its direction, a crater of some prominence generally marks the point, often forming a node, or crossing-place of other ridges, which thus appear to radiate from it as a centre. Sometimes they intrude within the smaller ring-mountains, passing through gaps in their walls as, for example, in the cases of Madler, Lassell, &c.
Finally, we turn to the nebula 826. This is planetary in form and inconspicuous, but Lassell has described it as presenting a most extraordinary appearance with his great reflector a circular nebula lying upon another fainter and larger nebula of a similar shape, and having a star in its center.
Lassell must have been a most indefatigable worker as well as a most ingenious man; for, besides constructing his own instruments, he has found time to make discoveries. He is, besides, very genial and pleasant, and told me some good anecdotes connected with astronomical observations. "One story pleased me very much. Our Massachusetts astronomer, Alvan Clark, has long been a correspondent of Mr.
ARZACHEL. Another magnificent object, associated on the N. with Alphonsus, about 66 miles in diameter, and encircled by a massive complex rampart, rising at one point more than 13,000 feet above a depressed floor. LASSELL. This ring-plain, some 14 miles in diameter, is irregular both as regards its outline and the width of its rampart.
Raymond, who sat sewing on her own porch, opened the solitary letter the postman handed her, and proceeded to acquaint herself with its contents in full view of the watchers on the other side of the street. "This must be Mother's Day," Amy exclaimed disapprovingly, when, a moment later, she accepted from the letter-carrier's hand a fat blue envelope directed to Mrs. Gibson Lassell.
I had also the pleasure of assisting other astronomical friends, by casting and grinding specula for them. Among these I may mention my late dear friend William Lassell, and my excellent friend Warren de la Rue, both of whom have indelibly recorded their names in the annals of astronomical science.
