***Something similar might be said about Substitute Fonts as Palmerston said about the Schleswig-Holstein question "[It] is so complicated, only three men . . . have ever understood it. One was Prince Albert, who is dead. The second was a German professor who became mad. I am the third and I have forgotten all about it.”
