 Most of the maps of this edition (eighteen of them) are found in a single 195-page article, "Geography".The second edition improved greatly upon the 1st, but is still notable for the large amount of now-archaic information it contained.For example, "Chemistry" goes into great detail on an obsolete system of what would now be called alchemy, in which earth, air, water and fire are named elements containing various amounts of phlogiston.
