We trust that the lower advertising rates now 
offered will lead all publishers of standard books 
to use space regularly in The Popular Science 
Monthly. They can thus reach most directly and 
at the lowest cost those who read, purchase and 
recommend scientific books and those who buy 
standard books of all kinds. We shall also wel¬ 
come the cooperation of authors who appreciate 
the advantages of seeing their books advertised 
where they will be brought to the attention of 
those interested.

and the advertising of 
scientific hooks.

NEW YORK : Sub-Station 84. 
The Popular Science Monthly is now the best 
place to advertise scientific books. Since its estab¬ 
lishment in 1872 the Monthly has reached those 
people who are most likely to read and purchase 
hooks of a scientific character. Its former adver¬ 
tising charges of fifty dollars a page were not high 
considering the audience addressed. There are 
now good magazines with less than half the cir¬ 
culation of the Monthly which charge those rates 
and good journals with one-tenth its circulation 
which charge half these rates. 
But while The Popular Science Monthly is 
stronger than ever before, its advertising rates 
have recently been reduced to $10 net a page. 
This reduction has been made because we should 
rather print two hundred pages of publishers’ 
announcements a year at $10 a page than forty
