PEOSPECTUS. 



At the close of the seventh volume of " Science " we wish to call attention to its work 

 of the past, and to its plans for the immediate future. 



It is the intention of the promoters of the journal to make a weekly paper which shall 

 keep its readers au coarant with the progress of scientific investigation in all fields. 

 " Science " does this in the following ways : — 



i°. It publishes timely geographical articles and maps, and by such articles as that on 

 artificial butter (May 28), or that on the oil and gas wells of Ohio in the present number, 

 keeps its readers posted on matters of public moment. 



2°. It publishes letters from correspondents in London, Paris, Vienna, St. Petersburg, 

 and Tokio, which give a clear idea of what is under discussion by scientific men abroad. 



3 . It has published a portion of a series of articles by the leading writers on economics 

 in America, which are intended to bring out what the new school of economists have to 

 propose. To this series have contributed Professors Sumner and Hadley of Yale, Laughlin 

 and Taussig of Harvard, Newcomb of Washington, Ely of Johns Hopkins, James of 

 Philadelphia, and Seligman of New York. The series will be completed within a few weeks 

 by other well-known contributors. 



4 . By reviews, abstracts, and brief notes, it gives the gist of the published work of 

 scientific investigators the world over. 



It is proposed during the coming year to pursue much the same course as in the past 

 year, believing, from the evidence which comes to us, that the journal is meeting a want in 

 American periodical literature, and only hoping, by increased attention to details, to render 

 the result more satisfactory. 



Our offer of bound volumes to new subscribers expires on July t. 



SCIENCE, 47 Lafayette Place, New York.
