Stanley, p. 138.) Also the Arabs that navigated the Red Sea at the same period are shown by Varthema to have used the mariner's chart and compass (Travels, p. 31) .

The oldest of these maps which have been preserved, the socalled " Pisan chart," which belongs probably to the middle of the 13th century, and a set of eight charts, known by the name of its former owner, the Cavaliere Tamar Luxoro, of somewhat later date, are both the work of Genoese artists.
Having encouraged a warlike spirit in his people and having introduced firearms, Kamehameha attacked and overcame the chiefs of the other kingdoms one after another, until (in 1795) he became undisputed master of the whole group. He made John Young (c. 1775-1835) and Isaac Davis, Americans from one of the ships of Captain Metcalf which visited the island in 1789, his advisers, encouraged trade with foreigners, 2 Their discovery in the 16th century (in 1542 or 1555 by Juan Gaetan, or in 1528 when two of the vessels of Alvaro de Saavedra were shipwrecked here and the captain of one, with his sister, survived and intermarried with the natives) seems probable, because there are traces of Spanish customs in the islands; and they are marked in their correct latitude on an English chart of 1687, which is apparently based on Spanish maps; a later Spanish chart (1743) gives a group of islands 10 0 E.
Following the first chart of lines of equal variation compiled by Edmund Halley in 1700, charts of similar type have been published from time to time embodying recent observations and corrected for the secular change, thus providing seamen with values of the variation accurate to about 30' of arc. Possessing these data, it is easy to ascertain by observation the effects of the iron in a ship in disturbing the compass, and it will be found for the most part in every vessel that the needle is deflected from the magnetic meridian by a horizontal angle called the deviation of the compass; in some directions of the ship's head adding to the known variation of the place, in other directions subtracting from it.
On the 23rd of March 16 to he exchanged Lewisham for the rectory of Great Chart, Kent.
The Declaration of Independence was his political chart and inspiration.
The results were published in a General Chart of the Variation of the Compass in 1701; and immediately afterwards he executed by royal command a careful survey of the tides and coasts of the British Channel, an elaborate map of which he produced in 1702.
A third Thule expedition started in 1920 under the leadership of Lauge Koch, who proposed to explore the interior of Peary Land and to fill in certain gaps in the chart of the N.W.
Molineux's chart, published by Hakluyt about 1600, was Hudson's.
Captain James Cook in 1778 made surveys from which the first approximately accurate chart of the coast was published; but it was reserved for Vancouver in 1793-1794 to make the first charts in the modern sense of the intricate south-eastern coast, which only in recent years have been superseded by new surveys.
Each chart was furnished with a scale of miles.
Wagner, to the inexperience of the cartographers who first combined the charts of the separate basins of the Mediterranean so as to produce a chart of the whole.
Nicolaus Germanus, a monk of Reichenbach, in 1466 prepared a set of Ptolemy's maps on a new projection with converging meridians; and Paolo del Pozzo Toscanelli in 1474 compiled a new chart on a rectangular projection, which was to guide the explorer across the western ocean to Cathay and India.
He is best known by his marine chart (1569) and his atlas.
In 1576 Manuel de Mesquita Perestrello, commanded by King Sebastian to explore the coast of South Africa and report on suitable harbours, -made a rough chart, even then of little use to navigators, which is of value as exhibiting the most that was known of the country by its discoverers before the advent of their Dutch rivals, who established themselves at Cape Town in 1652.
31a level; thus fifteen years' observations at Aden show a maximum the first chart of the depths of the Atlantic between 52° N.
Distribution of Salinity.-A great deal of material exists on which to base a study of the surface salinity of the oceans, and Schott's chart published in Petermanns Mitteilungen for 1902 incorporates the earlier work and substantially confirms the first trustworthy chart of the kind compiled by J.
The Domesday Survey, besides testifying to the agricultural activity of the country, mentions over one hundred salt-works and numerous valuable fisheries, vines at Chart Sutton and Leeds, and cheese at Milton.
His first important astronomical work was a careful investigation of the libration of the moon (Kosmographische Nachrichten, Nuremberg, 1750), and his chart of the full moon (published in 1775) was unsurpassed for half a century.
The weights and money values are arranged on a vertical chart, the sides of which converge towards the pivoting centre of an index arm which is actuated by the weighing mechanism.
The two outer arcs of the chart are occupied by the scales for the weight of the goods in lb and oz., and the rest of the chart is occupied by a series of 25 concentric arcs which show the money values of the goods for 25 rates per lb.
Up to 2 lb the weight of the load is registered automatically on the chart in much the same manner as in the case of the automatic computing weighing machine already described.
When the load exceeds 2 lb one or more 2-lb weights are placed in the weights-pan, and the value of the portion of the goods corresponding to these 2-lb weights is computed, at the rate per lb, in the ordinary manner; and the value of the balance of the weight of the goods is read off the chart, and the two are added together.
And the disk also carries the index arm which plays past the vertical face of the chart, and indicates the weight and price up to 2-lb weight.
He executed besides a chart and forty drawings of the moon (published at GÃ¶ttingen in 1881), and calculated lunar tables from a skilful development of Euler's theory, for which a reward of boo() was in 1765 paid to his widow by the British government.
Still sailing northward, taking notes as he proceeded for a rough chart of the coast, and landing at Bustard and Keppel Bays and the Bay of Inlets, Cook passed over 1300 m.
The chart of the world by Juan de la Cosa, the companion of Columbus, is the earliest extant which depicts the discoveries in the new world (150o), Nicolaus de Canerio, a Genoese, and the map which Alberto Cantino caused to be drawn at Lisbon for Hercules d'Este of Ferrara (1502), illustrating in addition the recent discoveries of the Portuguese in the East.
The rates per lb are inscribed on the index arm at points corre - sponding to the values on the concentric arcs of the chart, and the [[[Automatic]] values are indicated on the chart by the toothed edge of the index arm.
This work was the first serious attempt to chart the weather on an extensive scale, and in it also the author first established the existence and theory of anticyclones.
A chart on an isographic projection, exhibiting all the stars contained in the Bonn Durchmusterung, was designed to show the laws according to which the stars down to the 9 - 10th magnitude are distributed over the northern heavens.
In spite of the increase of deep-sea soundings in the last few decades, they are still very irregularly distributed in the open ocean, and the attempt to draw isobaths (lines of equal depth) on a chart of the world is burdened with many difficulties which can only be evaded by the widest generalizations.
It is not known when and by whom the island was discovered, but under the name of Moni it appears on a Dutch chart of 1666.
Columbus, trusting to Toscanelli's misleading chart, looked upon the countries discovered by him as belonging to eastern Asia, a view still shared about 1507 by his brother Bartolomeo.
Bologninus Zalterius on a map of 1566, and Mercator on his famous chart of 1569, separates the two continents by a narrow strait which they call Streto de Anian, thus anticipating the discovery of Bering Strait by more than a hundred and fifty years.
- Mercator's Chart of the World (1569).
Edmund Halley, the astronomer, compiled the first variation chart of scientific value (1683), as also a chart of the winds (1686).
A chart, in French, is called carte hydrographique, marine or des cotes; in Spanish or Portuguese carta de marear, in Italian carta da navigare, in German Seekarte (to distinguish it from Landkarte), in Dutch Zeekaart or Paskaart.
