The Democratic Whig

From New York Tribune.

Gen. Van Rensselaer, recently ejected by the Accidental President from the Post-office at Albany to make room for a supple minion, publishes a brief card in the Commercial yesterday concerning his dismissal. He gives a copy of a letter which he received from the manager of the Union while it was the Tyler organ in this city—asking his support for their sheet, and insisting that he should enlist the other twenty-three postmasters in his county in their cause. Out of them all they thought one hundred good subscribers could be obtained! The General was justly indignant at this contemptible insult and never answered the letter. For this he was marked and without an hour's notice was supplanted by Mr. Wasson. The General concludes his letter with the following threat. If the infamy of the Tyler faction were not already as black as base dishonor can make it, we should apprehend that the General would give them trouble; but as he only threatens to prove treachery and falsehood upon John Tyler, we imagine his Accidency will still rest easy:

At a proper time I will show, without the fear of contradiction, that Mr. Tyler, when he first arrived at Washington to assume the reins of government, was decidedly & unequivocally in favor of the charter of a United States Bank, the proofs of which are in my hands: a statement of the remarks of Mr. Tyler on that subject was drawn up by a gentleman now abroad. It was left with me to be used to defend myself, if assailed, as I have been, by the acting President. But it was not to be made public on any other occasion.—In support of that statement an affidavit will be affixed.

I shall further show who nominated him at Harrisburg.

SOL. VAN RENSSELAER.
