The American Naturalist 
Will enable any one to keep abreast of the latest scientific intelligence in 
every department of natural science. Besides its longer articles it publishes 
eleven different departments of scientific intelligence, each one under the charge 
of an editor of the highest scientific standing. 
It will insert small advertisements of a non-commercial character free for 
its subscribers. For commercial advertisements intended to reach the eyes of 
scientific men its regular advertising pages will be found the best possible 
medium. 
Abstracts of original work published while investigations are in progress for 
the purpose of securing date of publication are especially adapted to its pages, 
and are gladly published. The audience thus secured is the very best. 
We think you will find it worth your while to make its acquaintance. To 
enable you to do this cheaply we will send a sample (back) number on — 
receipt of 10 cents in stamps or coin (regular price 40 cents).
