Unmeaningly

"Apropos of Van Balen, an artist who painted me lately had painted a blackamoor praying; and not filling his canvas, stuffed in his little girl aside of a blacky gaping at him unmeaningly; and then did not know what to call it."

"All unmeaningly I started a little argument that furnished you with some splendid discussions, and, though my name wasn't mentioned, I'll admit it."
