LOUISIANA STATE UNIVERSITY STUDIES 
Richard J. Russell, General Editor 
The Louisiana State University Studies was established 
to publish the results of research by faculty members, staff, 
and graduate students of the University. Manuscripts of ex- 
ceptional merit from sources other than aforementioned are 
considered for publication provided they deal with subjects 
of particular interest to Louisiana. 
The Studies originally appeared as a unified series con- 
sisting of forty-two numbers published between the years 1931 
and 1941. In 1951 the Studies was reactivated and is now be- 
ing issued in the following series: Social Sciences, Humanities, 
Biological Sciences, and Physical Sciences. Other series may 
be established as the need arises. 
The Studies in each series will be numbered only serially, 
without volume designation. 
Requests for exchanges should be addressed to the Gift and 
Exchange Division, Louisiana State University Library, Baton 
Rouge. All other communications should be addressed to the 
Louisiana State University Press, Baton Rouge.
