The greatest length of the new continent may be taken in a line from the mouth of the river Plata to the lake of Assiniboils. From the former it passes to the lake Caracara; from thence to Mataguais, Pocona, Zongo, Mariana, Morua, St. Fe, and Carthagena; it then proceeds through the gulph of Mexico, Jamaica, and Cuba, passes along the peninsula of Florida, through Apolache, Chicachas, and from thence to St. Louis, Fort le Suer, and ends on the borders of lake Assiniboils; the whole extent of which is still unknown. This line, which is interrupted only by the Mexican gulph (which must be looked upon as a mediterranean sea) may be about 2500 leagues long, and divides the new continent into nearly two equal parts, the left of which contains about 1,069,286-5/6 leagues square, and that on the right about 1,070,926-1/12; this line, which forms the middle of the band of the new continent, is inclined to the equator about 30 degrees, but in an opposite direction, for that of the old continent extends from the north-east to the south-west, and that of the new continent from the north-west to the south-east. All those lands together of the old and new continent, make about 7,080,993 leagues square, which is not near the third of the whole surface, which contains 25 millions of square leagues. It must be remarked, that these two lines, which divide the continents into two equal parts, both terminate at the same degree of southern and northern latitude, and that the two continents make opposite projections, which exactly face each other; to wit, the coasts of Africa, from the Canary islands to the coasts of Guinea, and those of America from Guiana to the mouth of Rio Janeiro. It appears, therefore, that the most ancient land of the globe, is on the two sides of these lines, at the distance of from 2 to 250 leagues on each side. By following this idea, which is founded on the observations before related, we shall find in the old continent that the most ancient lands of Africa are those which extend from the Cape of Good Hope to the Red Sea, as far as Egypt, about 500 leagues broad, and that, consequently, all the western coasts of Africa, from Guinea to the straits of Gibraltar, are the newest lands. So likewise we shall discover that in Asia, if we follow the line on the same breadth, the most ancient lands are Arabia Felix and Deserta, Persia, Georgia, Turcomania, part of Tartary, Circassia, part of Muscovy, &c. that consequently Europe, and perhaps also China, and the eastern part of Tartary, are more modern. In the new continent we shall find the Terra Magellanica, the eastern part of Brasil, the country of the Amazons, Guiana, and Canada, to be the new lands, in comparison with Peru, Terra Firma, the islands in the gulph of Mexico, Florida, the Mississippi, and Mexico.
