origin and presented in a similar all-round 

 way. The later exercises under this head are 

 listed according to their distribution in the 

 United States and not primarily according to 

 the class to which they belong. 



Taken as a whole, however, the volume has 

 few elements of weakness and many of 

 strength. It has been tested in practise with 

 beginning pupils and hence is not too ad- 

 vanced or specialized. It is a most valuable 

 contribution to educational geography and 

 ought to help strengthen and humanize phys- 

 ical geography teaching in our high schools, 

 and it should be remembered that for many 

 years such work has been unhuman, if not at 

 times almost inhuman.

The Principles of Electro-deposition. A lab- 

 oratory guide to electro-plating. By Sam-

This is one of those manuals designed for 

 the purpose of interesting further the purely 

 technical worker, so that he may be led to 

 learn something at least of the principles upon 

 which the operations he observes daily are 

 based. 



After considering the apparatus for the pro- 

 duction, regulation, and measurement of the 

 electric current; plating with copper, nickel, 

 iron, tin, zinc, silver, gold and brass are taken 

 up in detail, from the theoretical as well 

 as the practical viewpoint, the methods of 

 preparing the object for plating, as well as the 

 finishing, after that process is complete, also 

 being considered. This is followed by several 

 chapters on the methods for the qualitative 

 and quantitative analysis of the substances 

 employed in the various processes. 



Whether the worker will actually gain the 

 knowledge which the author hopes he may is 

 a question, for much depends upon the ele- 

 mentary knowledge which can be assumed to 

 be in the possession of the reader. One thing 

 is quite certain, however, — the readers, or at 



least some of them, will find their interest 

 greatly aroused by a perusal of this book, even 

 though it may not be thoroughly understood; 

 with the result that they may be led to seek 

 some school where a thorough training in the 

 subject may be acquired. Books of this t,ype 

 are of the greatest value, for it is to them that 

 we must look for the first step in that great 

 advance in industrial work — the perfect com- 

 bination of theory and practise.

SCIENTIFIC JOURNALS AND ARTICLES 

 Announcement is made of the establish- 

 ment of The Journal of the Washington 

 Academy of Sciences. It is to be a semi- 

 monthly publication and will be sent to sub- 

 scribers on the first and fifteenth of each month, 

 or during the summer may appear on the 

 fifteenth only, as double numbers. The first 

 number will be issued about July 15, but 

 after 1911 the volumes will correspond to the 

 calendar year. The present Proceedings of the 

 Washington Academy of Sciences will be dis- 

 continued after the completion of the cur- 

 rent volume. The Journal will be a medium 

 for the publication of original papers and a 

 record of scientific work in Washington. It 

 will accept for publication (1) brief papers 

 written or communicated by resident or non- 

 resident members of the academy; (2) ab- 

 stracts of current scientific literature pub- 

 lished in or emanating from Washington; 

 (3) proceedings and programs of the afiiliated 

 societies, and (4) notes of events connected 

 with the scientific life of Washington. The 

 editors are : George K. Burgess, Bureau of 

 Standards; Barton W. Evermann, Bureau of 

 Fisheries, and Frederick Leslie Ransome, 

 Geological Survey. Illustrations will be used 

 only when necessary, and will be confined to 

 text figures or diagrams of simple character. 

 The editors, at their discretion may call upon 

 an author to defray the cost of his illustra- 

 tions, although no charge will be made for 

 printing from a suitable cut supplied with the 

 copy.
