[5] The first volume was principally occupied with a detailed description of the countries of the world, while the second formed an atlas of twenty-two newly devised maps — two of the hemispheres, and four devoted to each of the five continents.
[10] This became a standard method of showing the two hemispheres of Earth during the nineteenth century after the equatorial stereographic projection popularized by Gerardus Mercator finally fell into disuse.
