Seite 470 - Olympian games or Pythian fields ; 530 Part curb their fiery steeds, or shun the goal With rapid wheels, or fronted brigades form. As when to warn proud cities, war appears Waged in the troubled sky, and armies rush To battle in the clouds, before each van Prick forth the airy knights, and couch their spears Till thickest legions close ; with feats of arms From either end of Heaven the welkin burns.
Seite 267 - Make a small Cross of two light Strips of Cedar, the Arms so long as to reach to the four Corners of a large thin Silk Handkerchief when extended; tie the Corners of the Handkerchief to the Extremities of the Cross, so you have the Body of a Kite; which being properly accommodated with a Tail, Loop and String, will rise in the Air, like those made of Paper; but this being of Silk is fitter to bear the Wet and Wind of a Thunder Gust without tearing.
Seite 219 - They retired from us with a wind at south-east, leaving an impression upon my mind to which I can give no name, though surely one ingredient in it was fear, with a considerable deal of wonder and astonishment.
Seite 267 - To the top of the upright stick of the cross is to be fixed a very sharp-pointed wire, rising a foot or more above the wood. To the end of the twine, next the hand, is to be tied a silk ribbon, and where the silk and twine join, a key may be fastened.
Seite 256 - ... 2. But if the persons on wax touch one another during the exciting of the tube, neither of them will appear to be electrised. 3. If they touch one another after exciting the tube, and drawing the fire as aforesaid, there will be a stronger spark between them than was between either of them and the person on the floor.
Seite 475 - On the 15th of August, 1643, as I stood at my window, I was surprised with a most wonderful, delectable vision. The sea that washes the Sicilian shore swelled up, and became, for ten miles in length, like a chain of dark mountains ; while the waters near our Calabrian coast grew quite smooth, and in an instant appeared as one clear polished mirror, reclining against the aforesaid ridge.
Seite 58 - It was indeed my opinion, as well as the opinion of most on board, that this ice extended quite to the pole, or perhaps joined to some land to which it had been fixed from the earliest time...
Seite 219 - ... majestic slowness ; at intervals we thought they were coming in a very few minutes to overwhelm us; and small quantities of sand did actually more than once reach us. Again they would retreat so as to be almost out of sight, their tops reaching to the very clouds.
Seite 257 - C standing on the floor, both appear to be electrified; for he, having only the middle quantity of electrical fire, receives a spark upon approaching B, who has an over quantity, but gives one to A, who has an under quantity. If A and B approach to touch each other, the spark is stronger; because the difference between them is greater. After such touch, there is no spark between either of them and C, because the electrical fire in all is reduced to the original equality.
Seite 219 - The same appearance of moving pillars of sand presented themselves to us this day in form and disposition like those we had seen at Waadi Halboub, only they seemed to be more in number and less in size.
