Moby-Dick 74-77

ch. 74:
This chapter talks a lot about how the sperm whale's eyes are on the side of its head so it can't see directly in front of itself or directly behind itself. This could be a foreshadow to someone figuring out that when they are in the water they can be in just the right position and harpoon the whale without it knowing what is coming, or it could be a foreshadow that the sperm whale will run into one of the boats because it can't see it.

ch. 75:
The end of this chapter compares the sperm whale to a Platonian (Plato the philosopher) which could suggest that the sperm whale has an unusual amount of intelligence for a whale. Since Moby Dick is a sperm whale this reference to Plato could reflect the smartness that the whale seems to show in always getting away.

ch. 76:
In this chapter, Ishmael talks about how the whale's head is made perfectly for ramming things. The features of its head are arranged and they have a hard enough head that they won't be hurt even if they ran into a ship. This could be a foreshadow to a whale hitting the Pequod and possibly causing some major damage.

ch. 77:
The Heidelberg tun in this chapter could represent the whaling industry. Like the tun, there is a lot of money in whaling, but it is a very dangerous (and possibly fatal) thing to do. The spermaceti that is leaked from the tun could be a symbol of the leaking away of men's lives while they are on a whaling ship.
