Dear Dr. Lederburg ;

In the report of the discussion following R.A. Fisher's
paper in Biometrics 1 (1948) it is said that you were intending
to publish same worx on the algebric treatment of tetrad
analysis.

This is a problem in which I am interested, and as I
have not been able to locate any recent work of yours on this
subject I should be grateful if you could tell me where it is

to be found, I should also be grateful for reprints when they
are available,

Yours sincerely,

NIA -
