Symmes' Theory of Concentric Spheres, Showing That the Earth is Hollow, Part 4

Let’s theorize our way to sleep with more about a hollow Earth that contains unseen multitudes. This time, the mystery of whales migrating under Greenland, groaning lakes, and rebuttals to five arguments against the theory, including the opinion that not being hollow is an ungodly waste of space. Science!
