Tue FIFTEENTH VOLUME OF THE AMERICAN NATURALIST.—We 
would call the attention of our subscribers to the fact that the 
present al contains 926 pages, or 120 more than the pre- 
ceding volum 
We shall doain the coming year the reviews of progress in 
different departments of natural science, and from the papers in 
hand and those promised can give the assurance that Volume 
XV, will, at least, not be inferior in variety and interest to its pre- 
decessors. 
As during the past fourteen years, we continue to invite the 
contributions of original notes and articles, and items of scientific 
news, and ask our friends to call the attention of those in any 
g 
stimulus in their reading and observations in the field. The 
larger our subscription list, the more matter and illustrations can 
we offer tò our patrons. 
We have pleasure in announcing the purchase of the subscrip- 
tion list and good will of the ‘‘ American Entomologist,” which 
will in future be represented by a new department of the NAT- 
URALIST, to be devoted exclusively to Entomology. It will be 
conducted by the distinguished scientist, Dr. C. V. Riley, whose 
accession to our editorial corps, we think, constitutes an im- 
portant era in the history of the AMERICAN NATURALIST.
