Charles Kingsley was a very kind-hearted, man, and could not bear to see anything in pain. One Sunday, as he was preaching his sermon in church, he stopped in the middle of it, stooped down, picked up something, and went into the vestry. He soon returned and went on with his sermon. After the service was over, some one asked him why he had stopped in the middle of his sermon. He answered that he had seen a butterfly lying on the floor, and he was afraid that he might tread upon it and kill it; so he picked it up and let it fly out of the vestry window.
