in the true and full sense of the word being settled, every thing else follows as a necessary consequence, and is established. It is very important, therefore, that books should be multiplied on this topic, and that the utmost pains should be taken by the clergy to indoctrinate the people and instruct fully converts concerning that loyal allegiance and unreserved obedience which all Catholics owe to the vicar of Christ. This book will be found to be one of the best. We have received also from London a very clever critique on "Janus," by F. Keogh, of the Oratory, and are glad to see that the learned Dr. Hergenröther, of Würzburg, is preparing an elaborate refutation of that mischievous production. The second part of F. Bottalla's work on the papacy is also announced as soon to appear. * * * * * GEOLOGY AND REVELATION; OR, THE ANCIENT HISTORY OF THE EARTH, CONSIDERED IN THE LIGHT OF GEOLOGICAL FACTS AND REVEALED RELIGION. By the Rev. Gerald Molloy, D.D., Professor of Theology in the Royal College of St. Patrick, Maynooth. London: Longmans, Green, Reader & Dyer. 1870. For sale by the Catholic Publication Society, New York. The author discusses in this volume two interpretations of the Mosaic account of creation: 1st, that a long interval may have elapsed between the creation and the work of the six days; 2d, that the six days themselves may be long periods of time; and shows that they are both admissible, and that the last corresponds pretty well with the present state of geological science. In a subsequent work, he proposes to discuss the question of the antiquity of man. Though he does not claim to have written a manual of geology, the first and larger part of the work is in fact an excellent compendium of the science, and is written in a remarkably interesting and readable style. A few such books would do much to remove the dislike and distrust of geology which still prevails to some extent among religious people, and perhaps also to convince scientific unbelievers. * * * * * REPORTS ON OBSERVATIONS OF THE TOTAL ECLIPSE OF THE SUN, Aug. 7, 1869.
