Seite 214 - We procure means of seeing objects afar off, as in the heaven and remote places ; and represent things near as afar off, and things afar off as near; making feigned distances. We have also helps for the sight far above spectacles and glasses in use; we have also glasses and means to see small and minute bodies, perfectly and distinctly...
Seite 321 - Machine on its interminable voyage. We all saw the lever turn. I am absolutely certain there was no trickery. There was a breath of wind, and the lamp flame jumped. One of the candles on the mantel was blown out, and the little machine suddenly swung round, became indistinct, was seen as a ghost for a second perhaps, as an eddy of faintly glittering brass and ivory; and it was gone — vanished!
Seite 214 - We have also perspective houses, where we make demonstrations of all lights and radiations ; and of all colours ; and out of things uncoloured and transparent, we can represent unto you all several colours : not in rainbows, as it is in gems and prisms, but of themselves single.
Seite 214 - ... highest about half a mile in height, and some of them likewise set upon high mountains, so that the vantage of the hill with the tower is, in the highest of them, three miles at least.

Seite 355 - On the first day of the last month of autumn, the sun and moon did not meet harmoniously in Fang.
Seite 213 - We have high towers; the highest about half a mile in height; and some of them likewise set upon high mountains; so that the vantage of the hill with the tower is in the highest of them three miles at least. And these places we call the Upper Region: accounting the air between the high places and the low, as a Middle Region.
Seite 214 - ... not in rain-bows, as it is in gems and prisms, but of themselves single. We represent also all multiplications of light, which we carry to great distance, and make so sharp as to discern small points and lines; also all colorations of light: all delusions and deceits of the sight, in figures, magnitudes, motions, colours: all demonstrations of shadows.
