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 

 time, contain articles summarising the existing state of knowledge in the various branches 

 of Gtenetics, but re^aews and abstracts of work published elsewheie will not, as a rule, be 

 inchided. Adequate illustration will be provided, and, where the subject matter demands 

 it, free use will be made of coloured plates. The Journal will be issued in parts as material 

 accumulates, and a volume, appearing, so far as possible, annually, will consist of four such 

 parts.
