The Period from 1921 to 1940 47 



Science was established in 1883 by Alexander Graham Bell and Gardner 

 G. Hubbard, following a short-lived weekly journal with the same title- 

 started by Thomas A. Edison in 1881. Science attained at the most a paid 

 circulation of only about 2000 and continually had a deficit. In 1893 the 

 Association voted it a subsidy of $750. In spite of this assistance it sus- 

 pended publication with the issue of March 2^,, 1894. At this juncture Dr. 

 Cattell purchased Science, resumed its publication on January 4, 1895, and 

 tilled all unexpired subscriptions. This was the beginning of the "New 

 Series," the issue of June 28, 1940, completing the 91st volume. After the 

 first year under the ownership of Dr. Cattell, Science neither received nor 

 sought any subsidies or gifts for its support. In 1900 Science became the 

 official journal of the Association. Immediately thereafter both the member- 

 ship of the Association and the circulation of Science rapidly increased. 



The Scientific Monthly completed its 50th volume with the June, 1940, 

 issue. During the entire period of the publication of these 50 volumes Dr. 

 Cattell was owner and editor of the journal.
