A new practical geographical grammar: Containing, proper definitions of the abstruse terms that most frequently occur in reading the first principles of astronomy; with a short account of the hypothetical philosophy of the ancients; and a more particular description of the copernican or solar system. Wherein, the magnitudes, distances, and positions of the planets are briefly treated of; to which is prefixed, an explanation of the artificial sphere, and of the appendants and surface of the celestial and terrestrial globes. With directions for performing the most useful and curious astronomical, and geographical problems performed on each; and, a general description of all the remarkable countries in the world; with their subdivisions, chief cities, longitudes, latitudes, bearings and situations. Collected from the best authors, and rendered intellible to the weakest capacity. Particularly adapted to the use of schools. The firmament and stars declare the great creator's skill
