The map published by Thevenot, and recently reproduced by Rich, Bancroft, and others, is incorrect in many particulars, especially with regard to this fact of the Arkansas being the lowest point reached by Marquette. Besides the two Relations (MS.) aforesaid, and the Marquette manuscripts, fragments of the Relations for the years 1674, 1676, 1678, and the following years, have been found, but incomplete. In addition to all these, Father Martin calls attention to one of the printed Relations, little known out of Italy, in the language of which it was written. It was printed at Macerata in 1653. A recent letter from Father Martin announces that he has completed translations into French and English, which will soon be published. It is the work of Father Francois Joseph Bressani, and is thus noticed by Charlevoix: "Father Bressani, a Roman by birth, was one of the most illustrious missionaries to Canada, where he suffered a cruel captivity, and severe tortures. He speaks little of himself in his history, which is well written, but which relates almost entirely to the Huron mission, in which he labored with great zeal so long as it continued. After the almost entire destruction of that nation, and the dispersion of the remainder, he returned to Italy, where he continued to preach until his death, with the greater success, inasmuch as he bore in his mutilated hands the glorious marks of his apostleship among the heathen."[F] The translation by Father Martin will be illustrated by maps and engravings. Recent letters from Italy announce further discoveries in the library of the Dominican Friars at Rome. We congratulate the historical student on the recovery of these and similar memorials of the early history of the country. Especially the labors of the Jesuit missionaries deserve to be more generally familiar to the readers of history; and we cordially respond to the sentiment of approbation with which the services of Dr. O'Callaghan and Father Martin have been greeted heretofore by the press.
