Corrigendum . . .196 
The publication of a paper in Biometrika marks that in the Editor's opinion it contains either in 
method or material something of interest to biometricians. But the Editor desires it to be distinctly 
understood that such publication does not mark assent to the arguments used or to the conclusions 
drawn in the paper. 
Biometrika appears about four times a year. A volume containing about 500 pages, with plates and 
tables, is issued annually. 
Papers for publication and books and offprints for notice should be sent to Professor Eabl Pea'rson, 
University College, London. It is very desirable that a copy of all measurements made, not necessarily 
for publication, should accompany each manuscript. In all cases the papers themselves should contain 
not only the calculated constants, but the distributions from which they have been deduced. Diagrams 
and drawings should be sent in a state suitable for direct photographic reproduction, and if on decimal 
paper it should be blue ruled, and the lettering only pencilled. 
Papers will be accepted in German, French or Italian. In the first case the manuscript should be 
in Eoman not German characters. 
Contributors receive 25 copies of their papers free. Fifty additional copies may be had on 
payment of 7/- per sheet of eight pages, or part of a sheet of eight pages, with an extra charge for 
Plates ; these should be ordered when the final proof is returned.
