In each of the magnetic observatories throughout the world an arrangement is at work, by means of which a suspended magnet directs a ray of light on a preparred sheet of paper moved by clockwork.
The doors were placed on the east and west sides; and to the north and south fronts were attached two round towers, whose inner diameter was about thirty-two feet, and which formed the observatories which had windows in their roof, that could be opened towards any part of the heavens. The accommodations for the family were numerous and splendid.
Considering that the highest value can be derived from their labors only by such a combination as I have described, we may say the result is worth an important fraction of what all the observatories of the world have cost during the past century. Such was, in a general way, the great problem of exact astronomy forty or fifty years ago.
A snug harbour having been found, the ship was warped into it, and places forthwith cleared in which the observatories, forge, and the tents were set up. By the suggestion of Captain Cook, wholesome beer was brewed from the leaves of a tree resembling the American black spruce; indeed, he at all times attended to the most minute points calculated to maintain the health of his people.
No one should be deterred or discouraged in the study of celestial objects by the apparent insignificance of his means of observation. The accompanying pictures of the planet Mars may serve as an indication of the fact that a small telescope is frequently capable of doing work that appears by no means contemptible when placed side by side with that of the greater instruments of the observatories.
Had she been rich or handsome simply, Alexander Von Humboldt would not have taken her to his home, and, seating himself beside her on the sofa, talked, as she says, "on all manner of subjects, and on all varieties of people. He spoke of Kansas, India, China, observatories; of Bache, Maury, Gould, Ticknor, Buchanan, Jefferson, Hamilton, Brunow, Peters, Encke, Airy, Leverrier, Mrs.
Professor Lockyer went on to state, however, that he is by no means altogether dependent upon the observations made at South Kensington. For certain purposes the Royal Observatory at Greenwich is in requisition, and there are three observatories at different places in India at which photographs of the sun-spots and solar spectra are taken regularly.
So that the business of astronomy, in these days, is no sinecure, as the reader perceives. And by another evidence, it is continually becoming less of a sinecure. Formerly, one or two men, Tycho, suppose, or, in a later age, Cassini and Horrox, and Bradley, had observatories: one man, suppose, observed the stars for all Christendom; and the rest of Europe observed him.
To do this in the most satisfactory way, it was necessary to make a careful study of the methods and system at the leading observatories of other countries in the line we were pursuing, especially Greenwich. Here I was struck by the superiority of their system to ours.
Similar difficulties oppose the theory that the pyramids were intended to serve as astronomical observatories. For while their original figure, however manifestly astronomical in its relations, was quite unsuited for observatory work, it is manifest that if such had been the purpose of pyramid-building, so soon as the Great Pyramid had once been built, no other would be needed.
