However, screwing up our courage, we advanced cautiously toward the monster, as he seemed no way disposed to move at our approach.  Then we halted and examined him more narrowly.  He was alive, for we saw his eye complacently looking at us, as Diogenes might have looked out of his tub at the passing crowd.  He was fully twenty feet long, with a huge unwieldy body and a big head.  The most curious thing about his head was a huge nose, or trunk rather, which hung down nearly half a foot below the upper jaw.  His skin was covered with short hair of a light dun colour, and he had a tail and fins like a seal.  While we were still in doubt what he could be, Mr Kilby overtook us, and laughingly seizing our hands ran up behind the monster.
