I am directed by 
Earl Russell to acknowledge the receipt
               of your letter of the 
2 Ultimo, referring,
               for His Lordship's consideration, a Despatch from the Governor of
               
British Columbia, making certain enquiries as to the rights of Great
               Britain with regard to the Navigation of a river
               flowing from the British Territory through Russian Territory.
               
 
            
            
               I am to state to you in reply
that
 that His Lordship referred
               the question to Her Majesty's Advocate General, a copy of whose
               opinion on the subject is enclosed herewith for the 
Duke of
                  Newcastle's information; and I am to request that you will, in
               laying the same before His Grace, express 
Lord Russell's opinion
               that it would not be expedient at present to raise any question
               on the subject with the Russian Government.
