Extract

It has come to my attention that results I reported (DeMars 1963) were incorrect.

In Table I the values for samples 4 through 7 in column 4 (Larvae-Dead-Rad.) should read 1, 10, 7, and 4 instead of 10, 7, 4, and 0. In Table II the values for sample 13 in columns 8 and 12 (Beetles of all stages-Live and Total-Rad.) should read 102 instead of 103.
