earth, and replace the eggs. To prevent the soil becoming too dry, I used to sprinkle a little water upon it—a drop here and there-and if by accident the water fell too near the eggs, the earwig became much excited, hurrying to and fro with her eggs, until they were all removed to a drier spot. On the other hand, if I omitted the water until the earth became dry, she would choose the dampest spot that remained in which to form her nest, and seemed to welcome the water-drops, drinking herself from them, and feeling the damp earth with her antennæ. She remained thus for three weeks, feeding on little pieces of beef or mutton, or an occasional fly; I did not then know that earwigs are mostly vegetable feeders, but it is clear they can eat other food when needful. The first time I dropped a newly-killed house-fly near her she looked at it intently, felt it with her antennæ, and then suddenly wheeled round and pinched it with her forceps, and being apparently satisfied that it could do no harm to her eggs, she began to devour it, and after an hour or two but little remained except the wings.
