On September 3, 1783, John Burgoyne, Duke of Albany and Viceroy of the Confederation of North America, contracted what was initially assumed to be a cold.
On September 3, 1966, Carter Monaghan was sworn in as the nineteenth Governor-General of the Confederation of North America. After the ceremony, Monaghan and his predecessor, Perry Jay, went into the governor-general's office to make their private farewells. Jay later reported that he told Monaghan, "I've left you one problem, and that can be summed up in a single word. It's Mercator."
