Henry Hutton having sailed on board a vessel at Manilla, in July, 1835, on a voyage to London, and the vessel never having been since beard of, nor any one on board, presumed to be dead. Henry Hutton, the master of the merchant ship Forth, a bachelor, sailed from the port of London in the month of November, 1834, on a voyage to Manilla, where he arrived on or about the 20th of May, 1835. In the month of July, 1835, he re-embarked on board the said ship from Manilla on his return to London, where the ship was expected to have arrived in about four months afterwards, but neither the ship nor any person on board have since been heard of. The ship and cargo were insured, and the underwriters had paid as upon a total loss. The party had made no will.
