From the Goddard correspondence, this 1/2 – 3/4 oz. letter was sent from Nathaniel Goddard in Boston to his brother Benjamin in Calcutta.
Sent by British Open Mail on an American packet, it was prepaid 42c in stamps to prepay the inland (2x5c) and sea post (2x16c). The North Atlantic Steamship Co. steamer Adriatic left New York on June 2 and arrived at Southampton on June 12. The letter traveled to Marseilles, where it took a succession of Peninsula & Oriental steamers to Bombay, and from there overland to Calcutta. The addressee paid the remaining postage of 14 Annas, which accounted for British and French transit and stemship fees.
