The Lobster. 348. American Lobster. comes out of its shell through a rent on the back, and is at first very soft; it at once increases in size, and in a few days its skin becomes as hard as the shell which it cast off. This shedding of the shell is neces- sary for the growth of this animal, for after the new shell hardens further growth is impossible. When a Lobster is ready to shed its shell, there are two hard, stone-like bodies at the sides of the stomach, and it is supposed that these furnish a part of the solid matter.
