Messrs. Mason and Sildell.
The accounts from Northern sources disagree in regard to the attitude of the British Minister respecting the seizure of Messrs. dason and Slidell. A dispatch from Washington, Nov. 19th, says his expressions of disapproval are open and unguarded, while later is patches contradict this so far as to avow that he has maintained a strict reserve. The Canadian papers come out squarely and denounce the act, and we confidently anticipate some thunder are long from the other side of the Atlantic. It is apparent, from various indications in the Northern papers, that there is a well-defined apprehension of trouble to issue from the blunder of the Illinois lawyer.
