The results are summarized in Figures 2 and 5; Figure 2 shows the results of exposures to temperatures causing primary chill coma, and Figure 5 the results of exposures to temperatures causing secondary chill coma. 1. Effect of the temperature, duration of cold exposure, sex, size, and acclima- tion temperature on mortality Combining all the data in Figure 2 it is seen that: ( 1 ) the lower the temperature, the more rapidly lethal effects occurred ; (2) each increase in (100%) 40 35 30 Q 25 LU 20 15 10 5 I (O 2°C. 8°C 2 46 8 10 12 14 16 18 20 22 24 26 28 DURATION OF EXPOSURE (min.)
