and Glenallan House, ostensibly for the sake of completing two essays, one on the mail-shirt of the Great Earl, and the other on the left-hand gauntlet of Hell-in-Harness. He regularly inquires whether Lord Geraldin has commenced the Caledoniad, and shakes his head at the answers he receives. En attendant, however, he has completed his notes, which, we believe, will be at the service of any one who chooses to make them public without risk or expense to THE ANTIQUARY.   Notes 1 Sandy Gordon's Itinerarium.   2 Ars Topiaria, the art of clipping yew-hedges into fantastic figures.
