The Journal of Genetics is a periodical for the publication of records of original 

 research in Heredity, Variation and allied subjects. The Journal will also, from time to

 of Genetics, but reviews and abstracts of work published elsewhere will not, as a rule, be 

 included. It will be issued in parts as material accumulates, and a volume will consist oi 

 three such parts.

 Journal of Genetics alone, unless the contrary is stated. 



Contributors will receive 50 separate copies of their papers free. A further 50 may be 

 had at cosu price : these should be ordered when the final proof is returned.
