UNIVERSITY OF OKLAHOMA BULLETIN 



The University Bulletin has been established by the uni- 

 versity. The reasons that have led to such a step are: first, 

 to provide a means to set before the people of Oklahoma, from 

 time to time, information about the work of the different depart- 

 ments of the university; and second, to provide a way for the 

 publishing of reports, papers, theses, and such other matter as 

 the university believes would be helpful to the cause of education 

 in our state. The bulletin will be sent post free to all who apply 

 for it. The university desires especially to exchange with other 

 schools and colleges for similar publications : 



Communications should be addressed:
