Last night's Gazette contains an order in Council announcing that
a treaty has been concluded, and is now subsisting, between Great Britain and the Grand Duke of Tuscany, by which that state is declared entitled to all the immunities enjoyed by the United States and Portugal, under the act of the 59th of George Ill., au- thorizing the conclusion of a commercial treaty with those two nations, and the act of the 8th and 9th Victoria for granting certain duties of customs.
Two gentlemen have arrived in the British metropolis from the Government of the United States of America, and, as we understand, miasioned by the American powers, for the purpose of making themselves officially acquainted with the ma- chinery and conduct of our bonding system, with the view of introducing it into the United States as a branch of commercial policy. These American gentlemen have been introduced by his Excellency the American Ambassador to our Board of Customs; and the principal members of the Board have received an intimation from the Foreign Secretary or the Prime Minister to pay the gentlemen every respect and attention, and to render them every practicable assistance in their commercial researches.—Times.
