"In _Genesis_," says M. Lartet, "no date can be found which sets a limit to the time at which primitive mankind may have made its first appearance. Chronologists, however, for fifteen centuries have been endeavouring to make Biblical facts fall in with the preconcerted arrangements of their systems. Thus, we find that more than 140 opinions have been brought forward as to the date of the creation alone, and that, between the varying extremes, there is a difference of 3194 years--a difference which only applies to the period between the commencement of the world and the birth of Jesus Christ. This disagreement turns chiefly on those portions of the interval which are in closest proximity to the creation. "From the moment when it becomes a recognised fact that the origin of mankind is a question independent of all subordination to dogma, this question will assume its proper position as a scientific thesis, and will be accessible to any kind of discussion, and capable, in every point of view, of receiving the solution which best harmonises with the known facts and experimental demonstrations."[1] Thus, we must not assume that the authority of Holy Writ is in any way questioned by those labours which aim at seeking the real epoch of man's first appearance on the earth. In corroboration of M. Lartet's statement, we must call to mind that the Catholic church, which has raised to the rank of dogma so many unimportant facts, has never desired to treat in this way the idea that man was created only 6000 years ago. There is, therefore, no need for surprise when we learn that certain members of the Catholic clergy have devoted themselves with energy to the study of pre-historic man. Mgr. Meignan, Bishop of Châlons-sur-Marne, is one of the best-informed men in France as respects this new science; he cultivates it with the utmost zeal, and his personal researches have added much to the sum of our knowledge of this question. Under the title of 'Le Monde et l'Homme Primitif selon la Bible,'[2] the learned Bishop of Châlons-sur-Marne published, in 1869, a voluminous work, in which, taking up the subjects discussed by Marcel de Serres in his "Cosmogonie de Moïse, comparée aux Faits Géologiques,"[3] and enlarging upon the facts which science has recently acquired as to the subject of primitive man, he seeks to establish the coincidence of all these data with the records of Revelation. M. l'Abbé Lambert has recently published a work on 'L'Homme Primitif et la Bible,'[4] in which he proves that the discoveries of modern science concerning the antiquity of man are in no way opposed to the records of Revelation in the Book of Moses.
