     Lunar eclipſes are not quite ſo complicated in theory, nor near ſo tedious and difficult in calculation, as ſolar ones. The latter are only apparent, the former really ſuch; that is, the Moon is really deprived of its light, and therefore muſt appear obſcured to all the inhabitants of the earth equally, by whom ſhe can be ſeen; whereas the Sun, not being deficient in light, will ever appear reſplendent to thoſe who do not happen to live on that part of the earth where the lunar ſhadows pass.

     You know nothing about fixing the lunar rays into a ſolid ſubſtance, but you muſt not therefore ſay that this is impoſſible. It can be done, and I can do it. Theſe rays, reduced to a ſubtle powder, and blown on the ſurface of the infant brain, ſtimulate it in future life, by their quality of pricking.

lunar (複数形 lunars)

1. (anatomy) The middle bone of the proximal series of the carpus in the wrist, which is shaped like a half-moon.

   Synonyms: intermedium, lunar bone, semilunar

     The carpal bones are usually described as being capable of being luxated from the lower end of the radius forwards or backwards, inwards or outwards. The case backwards, which has been stated to be the most frequent, is facilitated by the direction of the convex articular surfaces of the scaphoid, lunar, and cuneiform bones, which slope more backwards than forwards.]

     There are two larger bones of the wrist called the scaphoid and lunar; these form a large ball, and this is received into the lower end of the radius.

   • 1946, Evelyn Feiring, Rainbow of Being, Pasadena, Calif.: Holly, OCLC 632360741, page 155:

     The scaphoid and lunar (wrist bones) are separate, whereas in Carnivores they are united perhaps to give greater strength to the wrist.

2. (nautical, navigation) An observation of a lunar distance (“the angle between the Moon かつ another celestial body”), especially for establishing the longitude of a ship at sea.
   • 1859 October, Henry Toynbee, “A Few More Words on Lunars”, in The Nautical Magazine and Naval Chronicle: A Journal of Papers on Subjects Connected with Maritime Affairs, volume XXVIII, number 10, London: Simpkin, Marshall and Co. […]; and J. D. Potter, […], OCLC 845531299, page 511:

     [Y]oung beginners cannot be too often cautioned that a single lunar is of little or no value until the observer knows the usual difference between his lunars taken on opposite sides of the moon; and these should be taken with the same instrument, using the same screens and telescope, for he must remember that they may be expected to differ. My star lunars differ from three to four minutes, or say fifty miles of longitude; my sun lunars from one to two minutes, or say twenty minutes of longitude.

   • 2007, John Karl, “Lunar Distance Sights”, in Celestial Navigation in the GPS Age, Arcata, Calif.: Paradise Cay Publications; Wichita, Kan.: Celestaire, →ISBN, pages 96–97:

     With cheap quartz watches (several, for reliability) we can do all the modern celestial navigation we could want. But learning and practicing lunars gives us deeper insight into celestial navigation; an appreciation for their historical importance and difficulty; and perhaps most significant of all, after conquering lunars we can appreciate the great convenience of St. Hilaire sights and modern quartz watches. Moreover, in the rare event of losing UT, with lunars and only a poor watch we can still be confident of finding our longitude at sea (well, OK, to within 30′).
