O'CosneeLt's suppressed Letter "to the Reformers of England," (dated the
20th June), to which he alluded on Thursday, in his dispute with Mr. L/TTLETON, appears in the True Sun of this evening. It commences with a fierce attack on Earl Gner, the "wretched old man," who is charged with insanity, " and childish hatred and maniac con- tempt of the people of Ireland." The conduct of the Whig Ministers towards Lcland—their prosecutions of the press, even to the imprison- inent of the working pi inters—their levies of tithes during the night., by polices and dragoons—their suspension of the Habeas Corpus Act and trial by jury—their appointment of Lord ANGLESEA, whom the Duke of WELLINGTON called the greatest fool he ever saw, and sub- scquently of Lord WELLESLEY, nicknamed "Old Foozle," to the govern- ment of his eountry—their threatened renewal of the Coercion Bill— all these topics of irritation are dwelt upon by the Agitator, with his usual vehemence. The Letter concludes with an earliest call upen the People of England to come to the rescue of their Irish brethren, and drive out a Ministry, "weak at Court, weak in the Lords, weak in the wretched mediocrity of their talents, weak in the insanity of the Pre- mier, weak by the loss of character and consistency."
