The American Naturalist. 
PRP PIII REI EVIE tel a 
WITH 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 1898, 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.
