The Unity of the Human Races proved to be the Doctrine of Scripture, Reason, and Science. By the Rev. Thomas Smyth, D.D. New York: George P. Putnam. 12mo, pp. 404.

The question discussed in the present volume, is one that has excited great attention among modern savans, and more recently, has obtained a fresh interest from the speculations concerning it by the popular scientific lecturer Professor Agassiz of Harvard University. In many respects, Dr. Smyth has shown himself admirably qualified for the task he has undertaken. He brings to the discussion of the subject, the resources of great and various learning, the mature results of elaborate investigation, a familiarity with the labors of previous writers, and a lively and attractive style of composition. The argument from Scripture is dwelt upon at considerable length, and though presented in a forcible manner, betrays the presence of a certain tincture of professional zeal, which will tend to vitiate the effect on the mind of the scientific reader. Under the head of the Former Civilization of Black Races of Men, a great variety of curious facts are adduced, showing the original sagacity and advancement in all worldly knowledge and science, by which the family of Ham was distinguished. The testimony of a southern divine of such high eminence as Dr. Smyth, to the primitive equality in the intellectual faculties of the negro and European races, is not a little remarkable, and speaks well for his candor and breadth of comprehension. The discussion of the origin of the varieties in the human race is conducted with great ingenuity and copious erudition, but it must be admitted, hardly succeeds in making out a case to the satisfaction of the inquirer, who regards the subject only in the light of history and philosophy.

The influence of the theory which he opposes, on the relations of the Southern States, is considered by Dr. Smyth to be of a different character from that set forth by many writers. He believes that it would be suicidal to the South in the maintenance of her true position toward her colored population. The diversity of the Black and White races was never admitted by the fathers of the country. They always recognized the colored race which had been providentially among them for two centuries and a half as fellow-beings with the same original attributes, the same essential character, and the same immortal destiny. The introduction of a novel theory on the subject, Dr. Smyth maintains, would be in the highest degree impolitic and dangerous, removing from both master and servant the strongest bonds which now unite them, and by which they are restrained from licentious, immoral, and cruel purposes.

Without reference to many statements, which will produce the widest latitude of opinion in regard both to their soundness and their accuracy, the work of Dr. Smyth may be commended as a treatise of the highest importance in the scientific discussion to which it is devoted, abounding in materials of inestimable value to the student, filled with the proofs of rare cultivation and scholar-like refinement, and every way creditable to the attainments and the ability of the author and to the literature of the South.

Historical View of the Languages and Literature of the Slavic Nations; with a Sketch of their Popular Poetry. By Talvi. With a preface by Edward Robinson, D.D., LL.D. New York: George P. Putnam. 12mo., pp. 412.

It is rarely that a subject is treated with the profound investigation, vigorous analysis, and intelligent comprehensiveness which are exhibited in the discussion of the interesting literary topics to which the present work is devoted. The authoress, whose name is concealed in the mystic word Talvi, is understood to be the lady of Rev. Professor Robinson, and her rare accomplishments in various departments of learning have long since established her intellectual reputation in the most cultivated European circles. Usually written in her native German language, her productions are perhaps not so extensively known in this country, although few of our educated scholars are ignorant of her researches in a province of literature with which her name has become, to a great degree, identified.

The volume now published is characterized by the extent and thoroughness of its investigations, its acute and judicious criticisms, its warm-hearted recognition of true poetry, even in an humble garb, and the force and facility of its style. The last trait is quite remarkable, considering the writer is using a foreign language. There is little, either in the translations or the original portion of the work, to remind us that it is the production of one to whom the language is not native.

After describing the old, ecclesiastical Slavic Literature, the authoress proceeds to the literary monuments of the Eastern and Western Slavi, giving an elaborate account of the Russian, Servian, Bohemian, and Polish literatures, with glances at the achievements of several less important branches of the great Slavic race. In the course of this discussion, a great variety of rare and curious information is presented, of high importance to the student of ethnography and history, and accompanied with complete and lucid references to the original sources. The most attractive feature of the work to the general reader will doubtless be the sketch of the popular poetry of the Slavic nations, illustrated with abundant specimens of songs and ballads, many of which are marked with a strong natural pathos and tenderness, and all of them possessing a certain rustic simplicity, which is usually of a very pleasing character, and seldom offensive.

Hints toward Reforms, in Lectures, Addresses, and other Writings. By Horace Greeley. New York: Harper and Brothers. 12mo pp. 400.

A handsome volume, consisting principally of Lectures delivered before popular Lyceums and Young Men's Associations, with several brief Essays on subjects of popular interest. The distinguished author presents his views on the various topics which come under discussion with inimitable frankness and good humor, and in the fresh, flowing, unaffected style, which gives such a charm to the productions of his pen, even with readers who most strongly dissent from his conclusions. Among the questions considered in this volume are The Emancipation of Labor, The Ideal and the Actual of Life, The Formation of Character, The Social Architects, Alcoholic Liquors, Tobacco, The Trade Reform, The Church and the Age, Humanity, and several others of perhaps still more general interest. The admirers of the author, as well as all who are interested in the question of Social Reform, whether ranking themselves among the Conservatives or Progressives, will welcome this work as the only compact and systematic expression of his peculiar theories, now before the public, and as a valuable manual for reference on many points which engage a large share of attention at the present day.
