THE AMERICAN NATURALIST. 



This Illustrated Monthly Magazine of Natural History began its Sixth 

 Volume with number for January, 1872. 



Every number of the Naturalist contains 64 large 8vo pages of reading 

 matter, illustrated by plates and wood-cuts. All the leading Naturalists in the 

 country cordially support it and contribute to its pages. The aim of the 

 Editors is to make every number of the Magazine of importance to all persons 

 interested in Natural History, and to keep its readers informed as to the latest 

 discoveries and advances made in this progressive and popular science. No 

 teacher or student can now consider himself " posted" by simply studying the 

 latest text books, for they are necessarily old almost as soon as issued ; and it 

 is only by keeping informed of the daily progress of science through the medium 

 of such Magazines as the Naturalist that it is pbssible to keep up with the 

 times. Besides the leading articles in each number, there are the following 

 special headings, under which the miscellaneous and short notices are grouped : 

 Reviews and Book Notices. Botany, Geology, '/.oology, Anthropology, Microscopy, 

 Notes, Notices of Specimens for Exchange and Books Received.
