. A total of 203 bluegill sunfish ( Lepornis macrochirus , Rafinesque) which had been used in several acute zinc experiments carried out under varied environmental conditions were autopsied according to Mount's procedure for determining fish mortality due to zinc poisoning. Three classes of fish were used: those exposed to but not killed by zinc; those killed by zinc; and those not exposed to zinc. Two statistical tests were used to analyze these data and both tests gave results indicating significant differences (a = .05) between all three classes of fish. This indicates that the Mount autopsy technique is very probably a valid generalization. The possibilities of using Mount's technique as a predictive tool are discussed.
