In a spirited treatise on the ‘Origin of our Animal World’ Prof. L. Rütimeyer, in the year 1867, described the geological development and distribution of the mammalia, and the relationship of the different faunas of the past with each other and with that now existing. Although, since the appearance of that masterly sketch the palæontological material has been, at least, doubled through new discoveries in Europe and more especially in North and South America, this unexpected increase has in most instances only served as a confirmation of the views which Rutimeyer advanced on more limited experience. At present, Africa forms the only great gap in our knowledge of the fossil mammalia; all the remaining parts of the world can show materials more or less abundantly, from which the course followed by the mammalia in their geological development can be traced with approximate certainty.
Translated, with the permission of the author, by Dr. G. J. Hinde, V.P.G.S., etc., from the German, Aus den Sitzungsberichten der mathematisch-physikalischen Classe der k. bayer. Akad. d. Wiss. 1893. Bd. xxiii. Heft. II. pp. 137—198. The present treatise forms the concluding chapter of the 4th volume of the author's Handbook of Palaeontology, Munich, R. Oldenbourg, 1893.
