The American Naturalist is an illustrated monthly magazine 

 of Natural History, and will aim to present to its readers the leading 

 facts and discoveries in Anthropology, General Biology, Zoology, 

 Botany, Paleontology, Geology and Physical Geography, and Miner- 

 alogy and Petrography. The contents each month will consist of 

 leading original articles containing accounts and discussions of new 

 discoveries, reports of scientific expeditions, biographical notices of 

 distinguished naturalists, or critical summaries of progress in some 

 line ; and in addition to these there will be briefer articles on various 

 points of interest, editorial comments on scientific questions of the 

 day, critical reviews of recent literature, and a final department for 

 scientific news and personal notices. 



All naturalists who have anything interesting to say are invited 

 to send in their contributions, but the editors will endeavor to select 

 for publication only that which is of truly scientific value and at the 

 same time written so as to be intelligible, instructive, and interesting 

 to the general scientific reader. 



All manuscripts, books for review, exchanges, etc., should be 

 sent to The American Naturalist, Cambridge, Mass. 



All business communications should be sent direct to the 

 publishers.
