SCIENCE. 



[Vci. XVIII. No. 444 



only work devoted wholly to primary batteries available to Eng- 

 lish-speaking electricians and students, we believe, having been 

 an unsatisfactory treatise translated from the French. In pre- 

 paring this book the author has evidently had in mind the needs 

 of the student of electricity as well as of those whose occupation 

 requires some degree of familiarity with primary batteries for 

 practical purposes, as the work is admirably adapted to the wants 

 of both classes. The divisions of the subject appear to be as 

 logical as the nature of the material permits, each being fully 

 illustrated by the most useful types of cells. Prominence has been 

 given to standards of electromotive force, and a chapter is devoted 

 to testing, which will prove both interesting to the student and 

 useful as a laboratory guide 



Professor Tyndall's health is improving to such an extent that 



he is preparing for the press a volume of essays, addresses, and 

 reviews, to be issued under the title " Fragments of Science." 



— Ginn & Co. , publishers, announce for immediate publication 

 " The Story of Our Continent," a reading book in the geography 

 of North America, by professor N. S. Shaler of Harvard Univer- 

 sity, illustrated. The object of this book is to set before the stu- 

 dent a simple explanation of the way in which the continent of 

 North America has come to its present physical state, and at the 

 same time to show how this physical state affects the life of the 

 people. In other words, it seeks to secure a clear conception of 



the geography of the continent by showing in a very simple man- 

 ner the geological evolution of its features. It is adapted to the 

 needs of grammar schools, and may advantageously be used as a 

 reader in connection with a regular text-book in geography. As 

 an introduction, by the way of our own continent, to the study of 

 geology and physical geography, it will be found to possess a pe- 

 culiar value. 



— 2'he Climatologist is the title of a new monthly journal of 

 medicine announced by W. B. Saunders, 713 Walnut Street, Phil- 

 adelphia. The object of this journal will be to promote original 

 investigation, to publish papers containing the observations and 

 experience of physicians in this country and Europe on all mat- 

 ters relating to climatology, mineral springs, diet, preventive- 

 medicine, race, occupation, life insurance, and sanitary science, 

 and in that way to supply the means by which the general prac- 

 titioner and the public at large will become better acquainted 

 with the diseases of this country and Europe, and better armed 

 to meet the requirements of their prevention or cure. The editors 

 are Drs. John M. Keating, F. A. Packard, and Charles P. Gardi- 

 ner, who will have the co-operation of about thirty associate edi- 

 tors. The first issue, dated August, will be ready about the ]Oth>
