Philadelphia [October 22].
Saturday se'nnight arrived here a ship taken by the brig General Montgomery, she proves to be the ship Thetis, Capt. [Hezekiah] May, with 310 hogsheads of sugar, 90 puncheons of rum, &c. from Montego Bay for London, and belonged to a fleet of near 200 sail, who left Jamaica in August last, under convoy of two men of war. The above ship, in coming up, touched on the Cheveaux de Frize, where she would have, in all probability sunk, had it not been for the timely assistance she received from the Row Galley-men.
