AMONG THE PUBLISHERS. 

 John Wiley & Sons announce as in preparation "The Transi- 

 tion Curve Field-Book," by Clinton R. Howard, C.E. 



— John Wiley & Sons announce as in preparation "The Me- 

 chanical Engineer's Pocket Book," by William Kent. 



— Sister Rose Gertrude has written another article for The 

 Ladies' Home Journal for June, on "What it is to be a Leper," in 

 which she gives a clear glimpse of leper-life in Molokai, how the 

 disease is contracted, how it is treated and cured, and how the 

 lepers live in their exile. 



— D. C. Heath & Co. have in press for early publication an 

 " American Literature for High Schools and Colleges,"' by Julian 

 Hawthorne and Leonard Lemmon; also "French by Reading," 

 a new French method on the inductive plan, by Louise Seymour 

 Houghton and Mary Houghton. 



— • Among their books in press, J. B. Lippincott Company an- 

 nounces "The Chemical Analysis of Iron," by Andrew Alexander 

 Blair (new edition) ; " A Hand-Book of Industrial Organic Chem- 

 istry," by S. C. Sadtler; "Tables for the Determination of Min- 

 erals," by Persif or Frazer, jan. (new edition, revised and enlarged) ; 

 "Chambers's Encyclopedia,' Vol. VII. (entirely new edition, re- 

 vised and rewritten). 



— Messrs. Macmillan & Co. will publish next week a "Short 

 History of Greek Philosophy," for students and general readers, 

 by Dr. John Marshall, rector of the Royal High School, Edin- 

 burgh. The main purpose of this book is to present an account of 

 Greek philosophy which, within strict limits of brevity, shall be 

 at once authentic and interesting, — authentic, as being based on 

 the original works themselves; interesting, as presenting to the 

 ordinary English reader the great thoughts of the greatest men of 

 antiquity, on problems of permanent significance and value, in 

 language freed from technicality and abstruseness. 



— T. Fisher Unwin has nearly completed preparations for a 

 " History of the Press." The volumes will deal in the first place 

 with the British press, and afterwards with the continental press 

 and the American. In each case the history of the great journals 

 wiU be treated in connection equally with the political and social 

 events they have influenced, and the characters and methods of 

 the men who have directed them to these ends. In a few in- 

 stances a single journal has played a sufficiently conspicuous and 

 important part to furnish abundant materials for a single volume, 

 but in others the general characteristics of a section of the press 

 will combine many newspapers and personalities into one work. 

 The first volume will be devoted to the Times, and others have 

 been arranged to treat of "The Provincial Press," " The French 

 Press.'' " The German Press," " The American Press," and " The 

 Comic Press." The volumes wiU be issued under the general 

 editorship of Mr. Henry Norman. 



— " Spinning Tops " is an interesting and valuable addition to 

 the Romance of Science Series, published in London by the Soci- 

 ety for Promoting Christian Knowledge, and in this country by 

 E. & J. B. Young & Co. The volume is an expanded revision of 

 an "operatives' lecture," delivered by Professor John Perry at the 

 British Association meeting at Leeds in 1890. The changes neces- 

 sitated by the conversion of a lecture illustrated by actual experi- 

 ments with elaborate apparatus, into a treatise illustrated by 

 engravings and explanatory letterpress, have been carefully made; 

 and the result is a volume that will not only interest the general 

 reader, but also add considerable to his knowledge of some 

 branches of science. Beginning with a description of the behavior 

 of a spinning top, the author goes on step by step to the move- 

 ments of the earth in space, touching incidentally on the connection 

 between light and magnetism, and the rotation of the plane of 

 polarization, making his points clear at each step by means of ap- 

 paratus adapted to the purpose.

In dyspepsia the stomach 

 fails to assimilate the food. The 

 Acid Phosphate assists the 

 weakened stomach, making the 

 process of digestion natural and 

 easy. 



Dr. R. S. MoCoMB, Philadelphia, says: 



' ' Used it in nervous dyspepsia, with suc- 

 cess." 



Dr. W. S. Leonard. Hinsdale, N. H., 

 says: 



' ' The best remedy for dyspepsia that ha 

 ever come under my notice." 



Dr. T. H. Andrews, Jefferson Medical 

 College, Philadelphia, says : 



"A wonderful remedy which gave me 

 most gratifying results in the worst forms of 

 dyspepsia' '

The names of these scientists and educators are a guarantee of the quality and reliability of the work. 

 It is adapted in style and methods to pupils of fouiteen years and upward, and wh\\Q precedence to the 

 practical is the rule strictly adhered to throughout the work, no effort has been spared to inspire the 

 learner with enthusiasm in the study of Natural Science. It is singularly simple, practical, and at the 

 same time authoritative, and should be carefully examined by all who are looking for an accurate, com- 

 prehensive, judiciously condensed, entertaining text-book in Natural Philosophy.
