posed of the magazine element of the weekly. Although the pic- 

 tures will be, in the main, those employed in the weekly several 

 months ago, there will be new and attractive reading matter. If 

 it were not for this use of the plates the monthly would be an im- 

 possibility, the cost of making it being so great. The expense of 

 publishing a weekly magazine of the character of the Illustrated 

 American is so heavy that its price must necessarily be higher 

 than the long established weeklies. This price is the means of 

 deterring many thousands from purchasing it, and in order to 

 give people of small means a magazine at a nominal price it has 

 been decided to issue the monthly at one dollar a year. Those 

 who do not know the Illustrated American should ask for it the 

 next time they pass a news-stand. 



— G. P. Putnam's Sons have in press "The Living World: 

 Whence it Came, and Whither it is Drifting," a review of the 

 speculations concerning the origin and significance of life, of the 

 facts known in regard to its development, and suggestions as to 

 the direction in which the development is now tending, by H. W. 

 Conn, professor of biology in Wesley an University. 



— A. E. Seaton, who is connected with Earle's Shipbuilding 

 Company of Hull, England, will contribute to Scribner's steam- 

 ship series an article on " Speed in Ocean Steamers," to appear in 

 the July number. Commenting on the probability of " five-day 

 steamers" on the Atlantic the author says : "It is always a ques- 

 tion of cui bono, and when it is taken into consideration that the 



voyage between Sandy Hook and Queenstown is nowdone in 140 

 hours, and to do the distance in five days would require a speed of 

 nearly 33^ knots, with an increase in power of sixty-two per cent, 

 and in fuel consumption of thirty-eight per cent, the cry must be 

 regarded, as a. very far one at present. At the same time it is not 

 desirable to believe that there is now finality in the speed of steam- 

 ships, although by analogy with railway trains that conclusion 

 might be arrived at." 



— Macmillan & Co. have nearly ready for publication "A His- 

 tory of Human Marriage," by Dr. Edward Westermarck, lecturer 

 on sociology at the University of Finland, Helsingfors. In an in- 

 troductory note the work is commended to the attention of "Stu- 

 dents by Dr. A. E. Wallace, who expresses a high opinion of the 

 learning and insight displayed by the author. Dr. Westermarck 

 differs widely in many respects fi'om the opinions hitherto held 

 by most anthropologists as to the development of the various forms 

 of marriage. 



— S. E. Cassino, 196 Summer Street, Boston, announces that 

 the next edition of the " International Scientists' Directory " will 

 be issued in the first half of 1893, two years from the date of pub- 

 lication of the formei: one. It is hoped that the new edition will 

 contain nearly double the number of addresses given formerly, 

 and the editor will be greatly pleased to receive any names which 

 should be included. The foreign portion vpill be much more com- 

 plete than formerly.
