_Remak Rob. Untersuchungen über d. Enturckelung der Wirbelthiere_, Berlin, 1851. All who are interested in theories of the development of organic life will welcome the appearance of this work, which has been received with cordial approbation by the most eminent German physiologists. This second volume is devoted to the development of "the chicken in the egg," and is illustrated with seven admirable copper-plates. Notwithstanding the researches of Everard Horne, Ratke, and others into this department, this work of Remak's is distinguished by an even more accurate and detailed examination of phenomena, and it may confidently be classed among the first of the age. This is the opinion of _The Centralblatt_. The engravings are by Haase. This Robert Remak is the brother of Gustav Remak, an eminent German lawyer in Philadelphia. * * * * * In the _Archives for the Study of Modern Languages and Literature_ we observe a paper by one G. JAP, entitled, _Why does the English Language, in its acquisition and combination of new words, rather incline to the classic tongues than the copious and flexible German element?_ To which we may answer, "Alas, _why_, indeed?" Why is not the study of the Saxon Testament generally introduced? and why are not school-boys familiarized with the older forms of our own language--as they are in Germany made to study the Neibelungen Lied, and Wackernagel's Reader? We can imagine no argument in favor of a study of Greek which might not be with equal force applied to Saxon and good _old_ English. * * * * * A work has recently appeared in Breslan bearing the title, _The Higher Classes, as they are, and as they should be_, by Count ARNIM BLUMBERG: _written in the month of February, 1851_. That the aristocracy of Germany at the present day are far from being the practical philanthropists which they should be is beyond a doubt, but that they will become such by inspiring them with piety, in the unfortunate, melancholy sense in which that word is generally taken at the present day on the continent, is still more doubtful. _Not slothful in business, fervent in spirit, serving the Lord_, is piety in America--something contrasting remarkably with the mystical and world-renouncing _pietismus_ of modern Germany. * * * * * A second "completely renewed and greatly increased" edition of BERTHOLD AUERBACH'S _Deutsche Abende_, or German Evenings, has been published by Bassorman, of Mannheim. Auerbach is in this country rapidly attaining the popularity which was held a few years since by Zschokke. Apropos of the latter, we remark a neat and very cheap edition of all his works, now publishing by Sauerländer, of Aarau. * * * * *
