   “1836, Hans Christian Andersen (translated into English by Mrs. H. B. Paull in 1872), The Little Mermaid "Why have not we an immortal soul?" asked the little mermaid mournfully; "I would give gladly all the hundreds of years that I have to live, to be a human being only for one day, and to have the hope of knowing the happiness of that glorious world above the stars."”

   “The steamer itself had vanished, but the great scroll of smoke still hung in the air and drooped like a flag mournfully in valediction.”

   “So she dared not tell anyone how she felt, but went about mournfully, with a heavy heart.”
