THE AIMS AND OBJECTS OF THE SOCIETY 

 OF THE SIGMA XIi

 Society of the Sigma Xi that the president 

 shall explain the aims and objects of the 

 society to the members-elect. In the form 

 of initiation prescribed in the constitution

 to such students as have, during their college course, 

 given special promise of future achievement. 



Its motto is

 Society" shall be explained to the members- 

 elect, but leaves to the president great lati-
