The circular letter sent by William J. Onahan has just reached Donnelly through Father Patrick A. Halpin, S.J. It will be impossible for him to arrange to attend the meeting of the committee at Detroit, June 5th. He is in favor of the proposed Congress of Catholic laymen and believes it will be an important step in the advancement of Catholicity in this country. The Church is composed of the body of the faithful, and laymen generally forget it is their duty to bear an important part in her work, as members of the Church of Christ, and not leave the burden of the labor on the priesthood, as it has been left up to the present time, in the United States. In naming delegates to the Congress from Massachusetts the Committee should not forget to designate Dr. Thomas Dwight of this city, a highly educated, straight-forward Catholic who has occupied for some years past the Chair of Anatomy, formerly held in Harvard University by Dr. Oliver Wendell Holmes. :: III-3-c A.L.S. 2pp. 8vo.
