The great work of J. G. AUDUBON and the Rev. Dr. BACHMAN, upon the "Viviparous Quadrupeds of North America," is much praised by those persons in Europe whose praise is of most value. The _Athenaeum_ remarks that, hitherto, the mammalia of America have been known chiefly through descriptions by zoologists, in the Transactions of European Societies, and that no systematic attempt has been made to bring together into one connected view the very varied forms of animal life presented by this great continent, while these authors have not only used the materials which were at hand in the works of others, but have themselves observed with great diligence the habits of many of the creatures which they have described. "Their work is creditable to the United States, where a large number of subscribers have induced the authors to undertake it,--and a most valuable addition to our general natural-history literature." The geographical range within which the animals described in these pages are found is not that of the government of the United States merely; it comprehends Russian and British America, in fact, all the country which lies north of the tropics in the New World. * * * * * At the last MICHAELMAS BOOK FAIR at Leipsic, the Catalogue contained the titles of 5,023 new works published in Germany since Easter. This is from twelve to fifteen hundred more than at any fair since the Revolution of 1848. A great number of these books are large and of remarkable merit, being in some sort, the accumulation of the more profound scientific labors of the past two years. * * * * * The BARONESS VON BECK has just published in London two volumes of "Personal Adventures" in the Hungarian war. She is herself a Hungarian, and she saw her husband fall while cheering his men to defend a barricade at Vienna. In this book Kossuth is her hero, her prophet, her demigod; and she sacrifices all other celebrities without compunction at the altar of his greatness. Dembinsky she treats with manifest injustice; Georgey comes out on her pages as a very Mephistopheles. Klapka himself does not escape without animadversion. But without adopting her opinions, either of the man she blames or the subject she discusses, it cannot be denied that she has great cleverness, and a wonderful power of exciting and interesting the reader. * * * * *
