This changes the values in Table 11. The correct values for k are 0.00050,0.00062,and 0.0010 m/s, and the correct values for j are 0.83 X lo”, 1.0 X lo+, and 1.7 X g/(m2 s). These numbers are much smaller than previously given. They remain sufficient to account for the maximum rate of DDT flux found in the experiments and are, in fact, much closer to those values.
