A SHORT INTRODUCTION то. GEOGRAPHY and ASTRONOMY. G EOGRAPHY is that fcience which treats of the differ ent divifions of the globe into land and water, and fhews how to lay down these accurately on maps or globes.But tho', fly fpeaking, this comprehends the whole of the fcience, a fyftem of geography is always fuppofed to contain fomething of the natural hifory of the different countries, the manners of the inhabitants, and even a fketch of their ecclefiaftical and political history. The fcience of geography was very much unknown to the ancients. They had no good methods of finding either the longitude or latitude of places; and the imperfect ftate of navigation rendered them. fo gnorant of the greatest part of the world itfelf, that very little could be expected from them.-The conquefts of Alexander the Great proved very beneficial to the fcience, becaufe by that means many different nations were brought to a knowledge of each other, who were totally unconnected before. It was a cuftom alfo with every eral to make a furvey, and a kind of map of the country through which he paffed. This cuftom was kept up by the Romans, whose de extended empire might reasonably have been thought to give Ciderable opportunities for geographical obfervations. Yet, nothitanding all thefe affiftances, the firft fyftem of geography pubhed by Ptolemy about the middle of the fecond century was excordingly erroneous; the countries not only being diftorted in their ape which at that time were least known, but even thofe which lye round the mediterranean fea, and which were better known than any others. All this inaccuracy proceeded from the want of proper inftruments for making celeftial obfervations. The inequalities on the furface of the earth effectually prevent us from meafuring any confiderable portion of it exactly. The inftrument called the Surveying-wheel indeed tell us exactly the length of any road over which it paffes; bus |
