Examples

“If, in addition to our own amusements, we have, as we jogged carelessly laughing along, brushed away one tear of dejection and called forth a smile in its place — if we have brightened the pale countenance of a single child of sorrow — we shall feel almost as much joy and rejoicing as a slang-whanger does when he bathes his pen in the heart's blood of a patron and benefactor; or sacrifices an illustrious victim on the altar of party animosity.”
