On page 158, Mr. B. attacks Mr. J. A. Thome of Kentucky, with characteristic virulence, because, in a speech at an Anti-Slavery meeting, that young man had boldly exposed the abominations of slavery in his native state. For this act his slanderer calls him 'the ingrate who commenced his career of manhood, by smiting his parent in the face.' But he cautiously avoids attempting--what he was doubtless sensible would be a somewhat difficult task--to disprove the statements of Mr. Thome. It is a little remarkable that the facts stated by Thome, and denied by Mr. B. and his brother at the time, were confirmed abundantly by an article published in the Western Luminary, a Kentucky paper, on the very day on which Mr. Thome made his statement in New York. Thus without any concert or arrangement, two witnesses at a long distance from each other, testified to the same facts, and unfortunately for the credibility of Mr. Breckinridge, those were the facts which he was almost at the same time stoutly denying. Other witnesses of unimpeachable veracity, have since attested the same facts, and now Mr. B.'s impotent efforts to discredit Mr. Thome, only serve to show his own vexation, malignity and falsehood. We do not pretend to have noticed all the slips of Mr. B.'s 'unruly member' in this discussion, or to have pointed out every instance in which he has labored with all that ability and ingenuity which we readily admit he possesses, to create false impressions on the minds of his audience; but enough have been pointed out to show in some measure, the degree of confidence which ought to be reposed in his veracity as a witness and his candor and fairness as a reasoner.
