 of Columbia College, New York, Mr. Ives of Philadelphia, and to 

 nearly all the leading bouses engaged in photo-mechanical work 

 in New York, Philadelphia, and Boston. Permit me to add that 

 further assistance, from whatever quarter it may come, will be 

 gladly accepted and duly acknowledged.

BOOK-REVIEWS. 



An Easy Method for Beginners in Latin. By Albert Haek- 

 NESS. New York, American Book Company. 12°. 



This new volume by Professor Earkness approaches the Latin 

 language on what may be called its practical side, being intended, 

 not as a mere companion to tlie grammar, but as a useful guide 

 in the work of reading, writing, and speaking the language. It 

 is at once a book of exercises and a reader, containing enough 

 grammar to sufBce for the beginner. From the outset practical 

 use is made of the language as such, the complete sentence— verb, 

 subject, and object— being introduced in the very first chapter. 



The exercises throughout the book are mainly conversational; 

 and great care has evidently been taken to select interesting and 

 instructive subjects, to present them attractively, and to en- 

 liven them by the frequent introduction of anecdotes, stories, dia- 

 logues, etc. Questions in Latin on the subjects treated are intro- 

 duced regularly, not to be translated, but to be answered in Latin, 

 treating the language to some extent as a living instead of a dead 

 one. This must greatly lighten the task of the learner, though it 

 need nut necessarily endanger the thoroughness of his work. 



The method of treatment adopted by Professor Harkness in this 



work is largely inductive. Grammatical principles are presented 

 to the learner embodied and illustrated in the language itself, 

 before he is called upon to use them in constructive work. It 

 must not be understood from this that the grammar has been 

 neglected. Ttissimplyapproachedfromadilferent point, introduced 

 as needed in the exercises, and applied in a way that lightens the 

 task of learning it, and fastens it in the memory by immediate and 

 constant use. The book is illustrated by four full-page colored 

 plates and a number of engravings of classical subjects treated of 

 in the text and reproduced from authentic sources. On the 

 whole, the new volume is a -valuable addition to the series of 

 Latin test- books by the same author, so well-known to our edu- 

 cators. 



AMONG THE PUBLISHERS. 



In the November Magazine of American History, Rev. Charles 

 H. Parkhurst contributes the opening chapter, "Divine Drift in 

 Human History." The second article, "American Outgrowths of 

 Continental Europe," by the editor, is based upon the " Narrative 

 and Critical History of America." It is followed by Gen. Win- 

 field Scott's "Remedy for Intemperance," from Hon. Charles 

 Aldrich; " The Puritan Birthright," by Nathan M. Hawkes; and 

 "The Action at Tarrytown, 1781," by Dr. R B. Coutant. One 

 of the longest papers in the number is that of Dr. Prosper Bender, 

 the third in his series of " The J'rench-Canadian Peasantry." The 

 "Library of a Philadelphia Antiquarian," by E.' Powell Buckley, 

 will be perused with interest by all scholars. "Revolutionary 

 Newburgh " is an historic poem by Rev. Edward J. Runk. A 

 glimpse of the " Literature of California" is from the writings of 

 Hubert Howe Bancroft. 



— The Illustrated American gives a new point to a well-worn 

 problem. It says, "When a wheel is in motion, does the top 

 move faster than the bottom? Nine people out of ten would cry

12^. 50 cents. 

 It is only within very recent years that this 

 department of research has been cultivated; and 

 it is natural that the results of different workers, 

 involving variations in method and design, 

 should show points of difference. In spite of 

 these it seems possible to present a systematic 

 sketch of what has been done, with due reference 

 to the ultimate goal as well as to the many gaps 

 still to be filled.
