FOREIGN CONSPIRACY AGAINST THE LIBERTIES OF THE UNITED STATES.--2d edition. One excellence of the publication before us, almost peculiar to this writer, when compared to others who have written upon this subject in our country, is, that it handles the matter of discussion with calmness, the writer not suffering himself to indite his letters under the influence of exacerbated feelings, but wisely avoids those harsh and blackening epithets which do more to irritate the passions than to convince and enlighten the judgment. On this account the book may be read with profit by all.--_N. Y. Christian Advocate._ (Methodist.) The letters of Brutus deserve an extensive circulation.--Missouri, _St. Louis Observer_. (Presbyterian.) "From what I have seen and know, the fears entertained by the writer in the New-York Observer, under the caption of 'Foreign Conspiracy,' &c. are not without foundation, especially in the West."--_Letter of a Traveller in the West._ (Maryland,) _Methodist Protestant._ "BRUTUS.--The able pieces over this signature, relative to the designs of Catholicity in our highly favored land, originally published in the New-York Observer, it is now ascertained were written, not by an individual who was barely indulging in conjectures, but by one who has witnessed the Papacy in all its deformity. One who has, not long since, travelled extensively in the Romish countries, and has spent much time in the Italian States, where the seat of the Beast is. Rome is familiar to him, and he has watched the movements there with great particularity. We may, therefore, yield a good degree of credence to what Brutus has told us. His numbers are now published in a pamphlet, and the fact which has just come out in regard to his peculiar qualification to write on this great subject, will give them extensive circulation."--_Utica Baptist Register._ _The numbers of Brutus._--"Our readers are already acquainted with their contents. The object is to awaken the attention of the American public to a design, supposed to be entertained by the despotic governments of Europe, particularly of Austria, in conjunction with his Holiness the Pope, to undermine gradually our free institutions by the promotion of the Catholic Religion in America. The letters are interesting, from the numerous facts which they disclose; and are deserving the careful attention of the citizens of these United States, who should guard with vigilance the sacred trust which has been confided to us by our fathers."--_N. Y. Weekly Messenger._
