His request was immediately granted, and thus it came about that Hansen's famous Tables de la Lune were dedicated to La Haute Amiraute de sa Majeste la Reine de la Grande Bretagne et d'Mande.
It is pleasantly situated at the junction of several small streams forming the river Lune, in a deep valley surrounded by high-lying moors.
To the north, west and south, a flat coastal belt, bordering the Irish Sea, with its inlets Morecambe Bay and Solway Firth, and broadest in the north, marks off the Lake District, while to the east the valleys of the Eden and the Lune divide it from the Pennine mountain system.
Moon, lune), and he further took the name Astruc, Don Astruc or En Astruc of Lunel.
The principal tributaries on the right are the Aller, Wi mme, Drepte, Lune and Geeste, and on the left the Diemel, Nethe, Emmer, Werra, Aue and Hunte.
Hippocrates of Chios (c. 430 B.C.), the discoverer of the square of a lune, showed that the problem reduced to the determination of two mean proportionals between two given lines, one of them being twice the length of the other.
3), and of two non-concentric circles a " lune, " the shaded portions in fig.
The area of a lune or meniscus is expressible as the difference or sum of two segments, and the circumference as the sum of two arcs.
It is easily shown that the areas of the lune Adbea and the triangle ABC are equal.
The Mean Motion Of The Moon In Longitude, From The Mean Equinox, During A Julian Year Of 365.25 Days (According To Hansen'S Tables De La Lune, London, 1857, Pages 15, 16) Is, At The Present Date, 13X360° 477644"'409; That Of The Sun Being 360° 27".

The following are his most important works: Sur la figure de la terre (Paris, 1738); Discours sur la parallaxe de la lune (Paris, 1741); Discours sur la figure des astres (Paris, 1742); Elements de la geographie (Paris, 1742); Lettre sur la comete de 1742 (Paris, 1742); Astronomie nautique (Paris, 1745 and 1746); Venus physique (Paris, 1 745); Essai de cosmologie (Amsterdam, 1750).
The most important of these are his memoirs "Sur les inegalites seculaires des moyens mouvements des planetes," "Sur la variation des constantes arbitraires dans les questions de mecanique," both published in the Journal of the Ecole Polytechnique (1809); "Sur la libration de la lune," in Connaiss.
His first work on this abstruse subject, entitled T heorie des perturbations de la lune, qui sont dues a faction des planetes,1 is remarkable for the boldness of its conception, and constitutes an important addition to celestial dynamics.
On the north-west side of the Pennine system, marked off from it by the upper valleys of the rivers Eden and Lune, lies the circular hill-tract whose narrow valleys, radiating from its centre somewhat like wheel-spokes, contain the beautiful lakes which give it the celebrated name of the Lake District.
The four prominent groups of high land rising from the plain of the Red Rocks are: (1) the Lake District, bounded by the Solway Firth, Morecambe Bay and the The valleys of the Eden and the Lune; (2) the Pennine western.

Delaunay, developed in his Theorie du mouvement de la lune (2 vols., 1860, 1867), because it contains a germ which may yet develop into the great desideratum of a general method in celestial mechanics.

In the case of the expressions bien or mal lune, well or ill mooned, avoir un quartier de lune dans la tete, to have the quarter of the moon in one's head, the German mondsiichtig and the English moonstruck or lunatic, the fundamental idea lies in the strange opinions formerly held about the moon.
