In front of each man was a small microscope under a glass shade, a pair of balances and a rack filled with shallow porcelain trays. Evidently the work on which they were engaged did not endanger their eyesight, for the eye-pieces in the masks were innocent of protective covering, a circumstance which added to the hideous animal-like appearance of the men.
1st- a brass Sextant of 10 Inches radius, graduated to 15 which by the assistance of the nonius was devisible to 15"; and half of this sum by means of the micrometer could readily be distinguished, therefore-7.5" of an angle was perceptible with this instrument; she was also furnished with three eye-pieces, consisting of a hollow tube and two telescopes one of which last reversed the images of observed objects. finding on experiment that the reversing telescope when employed as the eye-piece gave me a more full and perfect image than either of the others, I have most generally imployed it in all the observations made with this instrument; when thus prepared I found from a series of observations that the quantity of her index error was 8' 45"; this sum is therefore considered as the standing error of the instrument unless otherwise expressly mentioned. the altitudes of all objects, observed as well with this instrument as with the Octant were by means of a reflecting surface; and those stated to have been taken with the sextant are the degrees, minutes, &c shewn by the graduated limb of the instrument at the time of observation and are of course the double altitudes of the objects observed.
"Flood ballast tanks depth thirty metres full speed ahead!" He thrust the helmsman aside and took the useless wheel himself. "Ludwig," he said, "to the periscope with you and tell me what you see." The Second-in-Command waited for no second bidding; he pressed his face against the eye-pieces. "There are small vessels approaching very swiftly from all sides," he said.
The eye-pieces gave a singularly sinister expression to his sallow face, and his disorderly hair looked like a wig of twisted black wire, while the jerkin he wore seemed almost dropping from his long, sinewy frame. He made his sharp weapon whistle three or four times in the air and tapped his foot impatiently upon the marble floor as though anxious to begin.
We found it necessary, therefore, to use great caution in handling our sextants and other instruments, particularly the eye-pieces of telescopes, which, if suffered to touch the face, occasioned an intense burning pain; but this was easily remedied by covering them over with soft leather. Another effect, with regard to the use of instruments, began to appear about this time.
Short was aware of the risk of optical illusion in such matters, and therefore observed Venus with a second telescope; he also used four eye-pieces of different magnifying power. He says that Venus was very distinct, the air very pure, insomuch that he was able to use a power of 240. The seeming moon had a diameter less than a third of Venus's, and showed the same phase as the planet.
Then three leathern jerkins were taken from their sacks and examined to see whether every string and buckle was in order, then the arm and neck bandages, the iron eye-pieces, the gauntlets padded in the wrist, the long gloves and stout caps with leathern visors worn by the seconds, the regulation shirts for the combatants, the bottle of spirits for rubbing their tired arms, a couple of sponges, and a dozen trifles of all sorts in a word, all the paraphernalia of student warfare.
If several instruments are being provided, it would be well to have part of them equipped with objectives 3 and 7, and eye-pieces I. and III.
Natasha stood by him with her eyes fastened to the eye-pieces of the glasses watching for the white flag in breathless suspense. "One minute more!" said Arnold. "Stop, there it goes!" cried Natasha as the words left his lips. "His Majesty has yielded to circumstances!"
'I think you could manage it, if you tried harder, he whispered to Rex, during a short halt. 'Of course, answered Rex. 'What do you expect? Even through the iron eye-pieces Greif could see the colourless, stony stare of his friend's eyes.
