Globular CHART, a meridional projection, in which the distance of the eye from the plane of the meridian, upon which the projection is made, is supposed to be equal to the sine of the angle 45°. This projection comes the nearest of all to the nature of the globe, because the me-
ridians are placed at equal distances; the parallels also are nearly equidistant, and consequently the several parts of the earth have their proper proportion of magnitude, distance, and situation, nearly the same indeed as on the globe itself.
Hydrographic Charts, sheets of large paper, on which several parts of the land and sea are described, with their respective coasts, harbours, sounds, flats, rocks, shelves, sands, and so forth, together with the longitude and latitude of each place, and the points of the compass.
Selenographic Charts, particular descriptions of the spots, appearances, and maculae of the moon.
Topographic Charts, draughts of some small parts of the earth only, or of some particular place, without regard to its relative situation, as London, York, and so on.
