The American Naturalist. 
ae the September number the AMERICAN NATUR- 
ALIST passed into the hands of a number of persons 
well known in the history of natural science in America. 
They have elaborated plans looking to the material im- 
provement of the magazine in several important respects; 
and they aim to make it the equal of any scientific 
Magazine in the world. In order that they may carry 
out some rather expensive improvements a material 
increase in the subscription list is desirable, and there- 
fore the following offer is made. 
All new subscribers to the volume for 1808, paying 
the full subscription price of $4.00 a year in advance 
may obtain the back volumes for the years 1895, 1896, 
and 1897 (the current volume) upon the following terms : 
Any single volume will be sent upon payment of $2.00; 
any two volumes for $3.50; and all three volumes for 
$4.00 in addition to the regular subscription. 
This offer holds good until the stock of back 
volumes is exhausted.
