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

 included. 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. 



Papers for publication may be sent either to Mr Bateson, Manor House, Merton 

 Park, Surrey, or to Professor Punnett, Gonville and Caius College, Cambridge. Other 

 communications should be addressed to the University Press, Cambridge. 



Papers forwarded to the Editors for publication are understood to be offered to the 

 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 cost price : these should be ordered when the final proof is returned. 



The Subscription price for a volume is 30s. net (post free) payable in advance ; separate 

 parts 10s. each net. Subscriptions may be sent to any bookseller, or to Mr C. F. Clay, 

 Manager, Cambridge University Press, Fetter Lane, London, RC.
