Animal Survival Times

SUMMARY:
       The poisons data frame has 48 rows and 3 columns.

       The data form a  3x4  factorial  experiment,  the  factors
       being three poisons and four treatments.  Each combination
       of  the  two  factors  was  used  for  four  animals,  the
       allocation to animals having been completely randomized.

DATA DESCRIPTION:
       This data frame contains the following columns:

time:     The survival time of the animal in units of 10 hours.
poison:   A factor with levels 1, 2 and  3  giving  the  type  of
       poison used.
treat:    A  factor  with  levels  A,  B,  C  and  D  giving  the
       treatment.
