New Publication Planned 



In order to furnish greater ()])portunity for ihe pul)licati()n of the results of 

 research in genetics, the Princeton University Press is making ])lans to launch a 

 new jjeriodical to be called (knelics. It is hoped that the first number can 

 ajjpear in January, 1916. It will be under the control of a board of editors, chief 

 of whom will be Dr. George Harrison Shull, of the Carnegie Institution, Cold 

 S])ring Harljor, Long Island, N. V.. who has recently resigned his jjosition there to 

 become associated with Princeton University. Genetics, it is announced, will 

 accept only technical jjapers. the results of original research, and will therefore not 

 conflict with the Journal of Heredity, whose function is rather to inter])ret the 

 results of research lo those who would jjrodt in- ihem, but are not in a position to 

 follow the technical literature.
