The next letter from Mr. O'Connell, was written after the accession of the Whigs. It, too, evidently bore the impress of that controlling fact. The writer enumerated twelve measures (excluding Repeal) "without which no British minister should dream of bidding for the people of Ireland." On the whole, the letter, which was long and elaborate, was an unmistakable though very guarded advice to give another trial to the Whigs. Mr. O'Brien, in moving that it be inserted on the minutes, pressed his conviction that the "millions would never abandon Repeal." He concluded by reading a resolution, pro posed in 1842 and seconded by Mr. O'Connell himself, to the effect that the Whigs were as inimical to Repeal as the Tories; and that no honest Repealer could vote for a Whig representative. Mr. O'Brien, on this occasion, took a wrong course. Instead of moving that the letter be inserted on the minutes, he should have moved its rejection, as containing doctrines subversive of principle and inconsistent with the solemn pledges of the nation. He was, no doubt, influenced by a desire to preserve unanimity; but the unanimity which is based on the disruption of most binding obligations is weaker and more fatal than any division. One paramount advantage would result from at once joining issue with Mr. O'Connell--the question would be placed on its true ground, and the preposterous folly of the physical and moral force abstractions would never have been heard of. Mr. O'Connell appeared in Conciliation Hall on Monday, the 6th of July. He stated that his object was to ascertain the state of the registries, so as to resist the return of the anti-Repealers in any of the towns where a vacancy was likely to occur. But he added, "I will give no vexatious opposition." Here a voice cried "Dungarvan," with significant emphasis, a question Mr. O'Connell evaded with his usual dexterity. Four seats were then actually vacant; Dungarvan, Drogheda, Dundalk and Roscommon county. In the three former, there were clear majorities in favour of Repeal. That question admitted of no earthly doubt. It had been long before enquired into, and assurances the most unequivocal were transmitted to the Association. On motion of Mr. O'Connell, the question was referred to the committee.
