It is certain Mr. Archi!?ald Govan's vessel, and a number of Scotch passengers, are stopped, and the property seized, chiefly consisting of specie, to the amount of fifty thousand pounds, which, if condemned, will be no bad first fruits of your resolution of reprisal. The vessel being Govan's, I suppose will be. considered as American property, but the cash, I take for granted, was mostly collected for the principals in Scotland.
