AMONG THE PUBLISHERS. 



The agitation in the religious world has now come around to 

 the point which is treated in " An Honest Hypocrite," a novel by 

 the Rev. E. Staats DeGrote Tompkins, published by the Cassell 

 Publishing Co. 



— G. P. Putnam's Sons have just issued " Politics and Property; 

 or, Phronocracy." a treatise on a compromise between democracy 

 and plutocracy, by Slack Worthington. 



— Professor Lanciani contributes to the July number of the 

 Atlantic Monthly a paper on " Underground Christian Rome," in 

 which he tells of the discovery of the Christianity of an ancient 

 Roman family from the excavation of their ancient burial place. 

 This is followed by " The Old Rome and the New," sufficiently 

 described in its title, by Mr. W. J. Stillmau ; a paper by Bradford 

 Torrey on the "Male Ruby-Throat; " the " Story of a Long In- 

 heritance," by William M. Davis, which, though no one would 

 ever suspect it, is devoted to tornadoes. Mr. Nathaniel Southgate 

 Shaler's paper on " College Examinations," which will excite re- 

 mark, is among the other features of the number. 



— A valuable book for all interested in the numerous applica- 

 tions of electricity is T. O'Conor Sloane's ' ' Arithmetic of Elec- 

 tricity " (New York, Henley & Co. $1.). It is a practical treatise 

 on electrical calculations of all kinds, reduced to a series of rules 

 in simple form, and involving only the use of ordinary arithmeti- 



cal methods. Each rule is illustrated by one or more practical 

 problems, with a detailed solution of each one. There is also an 

 extensive series of tables, covering pretty thoroughly the field of 

 electrical work. It may be added, that, in addition to the arith- 

 metical solutions of the problems, there is given after each rule, 

 wherever practicable and useful, the usual algebraic formula. 



— In the Century for July Professor Edward S. Holden of the 

 Lick Observatory has a paper on popular astronomy, entitled, " A 

 Lunar Landscape," with pictures from negatives taken at the Lick 

 Observatory. 



— In their series of introductory science text-books, Macmillan 

 & Co. have published "An Introduction to the Study of Botany," 

 by Edward Aveling, fellow of University College, London. The 

 volume is intended as a guide to the study of botany, and assumes 

 on the part of the reader no knowledge of the subject. While in 

 its general plan the work is based on the syllabus of the science 

 and art department at South Kensington, it cannot fail to prove 

 helpful to all who take up the study of botany, no matter what 

 speicial end they may have in view. The boob has 371 illustrations, 

 and a glossary of over six hundred words. A novel feature is that 

 the pronunciation in English is given of every Greek work used to 

 show the derivation of the botanical terms. 



— Henry Holt & Co. will publish early in September a complete 

 "Text-Book of Elementary Physics," chiefly experin^ental, by 

 Edwin H. Hall, assistant professor of physics in Harvard College
