A Raven who did not like his black coat had the wish to grow as white as
a Swan. So he left his old friends and haunts, and went to the streams
and lakes, where he spent all his time washing and dressing his clothes;
but all was of no use, he was just as black as ever; and as he had not
had food that was good for him, he soon grew ill and died. _We cannot
change our skins._
