chunk: Later editions changed the plot as well, and noted these changes in a new preface for the book. The original edition had a plot line where Bumpo, the African prince, wishes he were white, so that he can marry the Sleeping Beauty. The Doctor, who is imprisoned by the prince's father, grants his wish in exchange for escape by bleaching him. In the original text, this process is accompanied by a strong smell of "burning brown paper". In American editions, there seems to have been a half-hearted attempt at weakening this by changing the bleaching agent to white covering cream; in still later editions, the poor prince Bumpo's ambitions are either changed via hypnosis or he wishes to be a lion. In the later case, he is given a potion that causes his hair to grow out into an impressive mane around his head. Ultimately, he is not excised entirely.
