THE AMEPJCAN NATURALIST. 



This Illustrated Montldy Magazine of Natural History begins its Seventh Volume 

 with the jSfumher for January, 1873. 



Everj' number of tlie Natuealist contiiiiis G4 large 8vo pages of reading matter, illus- 

 trated by plates and woodcuts. All the leading Naturalists in the Coniitry 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 NATiMiAi.isr that it is possible 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 — i?CTm(is and Book Notices, Botany, Geology, Zoology, Aiitliro- 

 pologti, Nirroxeojnj, Notes, Notices of Specimens for Exchange and Books Meceived.
