In my view, the Christian religion is the most important and one of the first things in which all children, under a free government ought to be instructed... No truth is more evident to my mind than that the Christian religion must be the basis of any government intended to secure the rights and privileges of a free people.

telescope

TEL'ESCOPE, n. [Gr. end, or at a distance, probably the latter, and to see.] An optical instrument employed in viewing distant objects, as the heavenly bodies. It assists the eye chiefly in two ways; first, by enlarging the visual angle under which a distant object is seen, and thus magnifying that object; and secondly, by collecting and conveying to the eye a larger beam of light than would enter the naked organ, and thus rendering objects distinct and visible which would otherwise be indistinct or invisible. Its essential parts are the object glass, which collects the beam of light and forms an image of the object, and the eye glass, which is a microscope by which the image is magnified.

TEL'E-SCOPE, n. [Fr. from Gr. τελος, end, or τηλε, at a distance, probably the latter, and σκοπεω, to see; It. and Sp. telescopio.]

An optical instrument employed in viewing distant objects, as the heavenly bodies. It assists the eye chiefly in two ways; first, by enlarging the visual angle under which a distant object is seen, and thus magnifying that object; and secondly, by collecting and conveying to the eye a larger beam of light than would enter the naked organ, and thus rendering objects distinct and visible which would otherwise be indistinct or invisible. Its essential parts are, the object glass, which collects the beam of light and forms an image of the object, and the eye glass, which is a microscope by which the image is magnified. D. Olmsted.


Tel"e*scope
  1. An optical instrument used in viewing distant objects, as the heavenly bodies.

    * A telescope assists the eye chiefly in two ways; first, by enlarging the visual angle under which a distant object is seen, and thus magnifying that object; and, secondly, by collecting, and conveying to the eye, a larger beam of light than would enter the naked organ, thus rendering objects distinct and visible which would otherwise be indistinct and or invisible. Its essential parts are the object glass, or concave mirror, which collects the beam of light, and forms an image of the object, and the eyeglass, which is a microscope, by which the image is magnified.

    Achromatic telescope. See under Achromatic. -- Aplanatic telescope, a telescope having an aplanatic eyepiece. -- Astronomical telescope, a telescope which has a simple eyepiece so constructed or used as not to reverse the image formed by the object glass, and consequently exhibits objects inverted, which is not a hindrance in astronomical observations. -- Cassegrainian telescope, a reflecting telescope invented by Cassegrain, which differs from the Gregorian only in having the secondary speculum convex instead of concave, and placed nearer the large speculum. The Cassegrainian represents objects inverted; the Gregorian, in their natural position. The Melbourne telescope (see Illust. under Reflecting telescope, below) is a Cassegrainian telescope. -- Dialytic telescope. See under Dialytic. - - Equatorial telescope. See the Note under Equatorial. -- Galilean telescope, a refracting telescope in which the eyeglass is a concave instead of a convex lens, as in the common opera glass. This was the construction originally adopted by Galileo, the inventor of the instrument. It exhibits the objects erect, that is, in their natural positions. -- Gregorian telescope, a form of reflecting telescope. See under Gregorian. -- Herschelian telescope, a reflecting telescope of the form invented by Sir William Herschel, in which only one speculum is employed, by means of which an image of the object is formed near one side of the open end of the tube, and to this the eyeglass is applied directly. -- Newtonian telescope, a form of reflecting telescope. See under Newtonian. -- Photographic telescope, a telescope specially constructed to make photographs of the heavenly bodies. -- Prism telescope. See Teinoscope. -- Reflecting telescope, a telescope in which the image is formed by a speculum or mirror (or usually by two speculums, a large one at the lower end of the telescope, and the smaller one near the open end) instead of an object glass. See Gregorian, Cassegrainian, Herschelian, ***and] Newtonian, telescopes, above. -- Refracting telescope, a telescope in which the image is formed by refraction through an object glass. -- Telescope carp (Zoöl.), the telescope fish. -- Telescope fish (Zoöl.), a monstrous variety of the goldfish having very protuberant eyes. -- Telescope fly (Zoöl.), any two-winged fly of the genus Diopsis, native of Africa and Asia. The telescope flies are remarkable for having the eyes raised on very long stalks. -- Telescope shell (Zoöl.), an elongated gastropod (Cerithium telescopium) having numerous flattened whorls. -- Telescope sight (Firearms), a slender telescope attached to the barrel, having cross wires in the eyepiece and used as a sight. -- Terrestrial telescope, a telescope whose eyepiece has one or two lenses more than the astronomical, for the purpose of inverting the image, and exhibiting objects erect.

  2. To slide or pass one within another, after the manner of the sections of a small telescope or spyglass] to come into collision, as railway cars, in such a manner that one runs into another.

    [Recent]
  3. To cause to come into collision, so as to telescope.

    [Recent]
  4. Capable of being extended or compacted, like a telescope, by the sliding of joints or parts one within the other; telescopic; as, a telescope bag; telescope table, etc.

Noah's 1828 Dictionary

First dictionary of the American Language!

Noah Webster, the Father of American Christian education, wrote the first American dictionary and established a system of rules to govern spelling, grammar, and reading. This master linguist understood the power of words, their definitions, and the need for precise word usage in communication to maintain independence. Webster used the Bible as the foundation for his definitions.

This standard reference tool will greatly assist students of all ages in their studies.

No other dictionary compares with the Webster's 1828 dictionary. The English language has changed again and again and in many instances has become corrupt. The American Dictionary of the English Language is based upon God's written word, for Noah Webster used the Bible as the foundation for his definitions. This standard reference tool will greatly assist students of all ages in their studies. From American History to literature, from science to the Word of God, this dictionary is a necessity. For homeschoolers as well as avid Bible students it is easy, fast, and sophisticated.

* As a note, I have purchased each of these products. In fact, as we have been developing the Project:: 1828 Reprint, I have purchased several of the bulky hard-cover dictionaries. My opinion is that the 2000-page hard-cover edition is the only good viable solution at this time. The compact edition was a bit disappointing and the CD-ROM as well.
