rays from the object-glass to pass into the straight body. Bi-noc′u-lar Tel′e-scope. (Optics.) A pair of telescopes mounted in a stand, and having a parallel adjustment for the width between the eyes. The tubes have a coincident horizontal and vertical adjustment for altitude and azimuth. Galileo invented the binocular telescope with which he experimented in the harbor of Leghorn on a vessel in rough weather in the year 1617, with a view to the more convenient observation of Jupiter's satellites on board ship. The invention has usually been attributed to the Capuchin monk Schyrleus de Rheita, who had much experience in optical matters, and was seeking to find the means of constructing telescopes which would magnify four thousand times. Bi′not. (Agriculture.) A kind of double-mold board-plow. (English.) Bird-bolt. A thick, pointless arrow to kill birds without piercing them. Bird-cage. A box or case of wire, small sticks, wicker, or other suit
nace. As such castings are never very sound, it is a method not often employed of late years. Op′e-ra-glass. A binocular telescope of the kind invented by Galileo, and with which that philosopher first observed the planetary disks and Jupiter's four moons. This has a plano-concave or double-concave eyeglass, so that the image is not inverted and little light is lost, thus securing great distinctness. See lens. The object-glasses are now made achromatic, and are adjusted simul lens.) For telescopic purposes, a combination of lenses is required, — an objective and an eye-glass. This was invented about 1608 by Lippersheim and by Galileo. The latter turned it on the moon, and saw the shadows of the lunar mountains; on Jupiter, and discovered his satellites; on Saturn, and saw his bulging sides. He supposed the planet to be triple, as his telescope was not of sufficient power to define the ring. He afterward saw the phases of Venus and the spots on the sun. The refl
ying coach set forth that, however incredible it may appear, this coach will actually (barring accidents) arrive in London four days and a half after leaving Manchester. Three years later the Liverpool flying coach undertook to do the distance between that city and London in three days. No great improvements in speed were made until Palmer, who, according to De Quincey, was twice as great a man as Galileo, because he not only invented mail-coaches (of more general practical utility than Jupiter's satellites), but married the daughter of a duke and succeeded in getting the post-office to use them. This revolutionized the whole business. The Manchester mail did its 187 miles in 19 hours; the Liverpool mail its 203 miles in 20 hours 50 minutes; the Devonport mail its 227 miles in 20 hours; the Holyhead mail its 261 miles in 26 hours 55 minutes; while the Edinburgh mail traveled its whole distance of 400 miles in 40 hours. Other light coaches carrying passengers only rivaled the mai
htness, in 1671, the fifth in 1672, and the third and fourth in 1684, with an object-glass of Campani's having a focal length of 100-136 feet. The two innermost, or the first and second, were discovered in 1788 and 1789 by Herschel, with his colossal reflector. The second satellite offers the remarkable phenomenon of performing its revolution around the principal planet in less than one of our days. The telescopes which Galilco constructed himself, and others which he used for observing Jupiter's satellites, the phases of Venus, and the solar spots, magnified four, seven, and thirty-two times in linear dimensions, — never more. The Arenarius of Archimedes says very distinctly that Aristarchus had confuted the astronomers who imagined the earth to be immovable in the center of the universe; that this center was occupied by the sun, which was immovable, like the other stars, while the earth revolved around it. Turning the invention to immediate account, Galileo discovered the
