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 Mine- 
ralogy 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 
te send in their contributions, but the editors will endeavor to select 
for publication seed that which is of truly scientific value and at the 
e n so as to be intelligible, instructive, and interesting 
to the general scientific reader.
