I hold in my hand the last Almanac of Gotha, for 1866, which is the diplomatic authority for the world, and has been for a century; and, by way of example, I turn to the diplomatic list for the Netherlands, where, it will be remembered, we are represented by a patriotic citizen, well known to most of us, who was once connected with the press,--Mr. Pike,--with the title of minister resident.
