Biometrika. A Journal for the Statistical Study of 



Biological Problems. Edited, in consultation with FRANCIS GALTON, 

 by W. F. R. WELDON, KARL PEARSON and C. B. DAVENPORT. 



It is intended that Biometrika shall serve as a means not only of collecting 

 under one title biological data of a kind not systematically collected or 

 published in any other periodical, but also of spreading a knowledge of such 

 statistical theory as may be requisite for their scientific treatment. 



Biometrika includes (a) memoirs on variation, inheritance, and selection in 

 Animals and Plants, based upon the examination of statistically large numbers of 

 specimens (this of course includes statistical investigations in anthropometry); 

 () those developments of statistical theory which are applicable to biological 

 problems; (c) numerical tables and graphical solutions tending to reduce the 

 labour of statistical arithmetic; (d) abstracts of memoirs, dealing with these 

 subjects, which are published elsewhere; and (e) notes on current biometric 

 work and unsolved problems. 



'Biometrika' appears about four times a year. A volume, containing 

 about 400 pages, with plates and tables, is issued annually. The subscription 

 price, payable in advance, is 30^. net per volume (post-free) ; single numbers, 

 IOJ. net. Volumes I. and II. (1902-3) complete, 30^. net per volume; bound 

 in buckram, ji. 145. 6d. net per volume.
