"The industry, sound judgment, and the excellent literary style displayed in this work, cannot be too highly praised."--_Boston Post._ =A BRIEF HISTORY OF CULTURE.= By JOHN S. HITTELL. 1 vol., 12mo. Price, $1.50. "He writes in a popular style for popular use. He takes ground which has never been fully occupied before, although the general subject has been treated more or less distinctly by several writers.... Mr. Hittell's method is compact, embracing a wide field in a few words, often presenting a mere hint, when a fuller treatment is craved by the reader; but, although his book cannot be commended as a model of literary art, it may be consulted to great advantage by every lover of free thought and novel suggestions."--_N. Y. Tribune._ =THE HISTORY OF THE CONFLICT BETWEEN RELIGION AND SCIENCE.= By JOHN W. DRAPER, M.D., author of "The Intellectual Development of Europe." 1 vol., 12mo. Cloth. Price, $1.75. "The conflict of which he treats has been a mighty tragedy of humanity that has dragged nations into its vortex and involved the fate of empires. The work, though small, is full of instruction regarding the rise of the great ideas of science and philosophy; and he describes in an impressive manner and with dramatic effect the way religious authority has employed the secular power to obstruct the progress of knowledge and crush out the spirit of investigation. While there is not in his book a word of disrespect for things sacred, he writes with a directness of speech, and a vividness of characterization and an unflinching fidelity to the facts, which show him to be in thorough earnest with his work. The 'History of the Conflict between Religion and Science' is a fitting sequel to the 'History of the Intellectual Development of Europe,' and will add to its author's already high reputation as a philosophic historian."--_N. Y. Tribune._ =THEOLOGY IN THE ENGLISH POETS.= COWPER, COLERIDGE, WORDSWORTH, and BURNS. By Rev. STOPFORD BROOKE. 1 vol., 12mo. Price, $2. "Apart from its literary merits, the book may be said to possess an independent value, as tending to familiarize a certain section of the English public with more enlightened views of theology."--_London Athenæum._ =BLOOMER'S COMMERCIAL CRYPTOGRAPH.= A Telegraph Code and Double Index--Holocryptic Cipher. By J. G. BLOOMER. 1 vol., 8vo. Price, $5. By the use of this work, business communications of whatever nature may be telegraphed with secrecy and economy. =D.
