Strips of gastric muscle preserved at 0 °C., 5 °C., 10 °C., 15 °C., 20 °C., which had to be obtained under three vastly different conditions, had the same survival time. Thus at 0 °C. the survival time was 324 hours, at 5 °C. 132 hours, at 10 °C. 50 hours, at 15 °C. 38 hours, at 20 °C. 30 hours. Q10 between 20 °C. and 10 °C. equals 1.66, between 15 °C. and 5 °C. equals 3.47, and between 10 °C. and 0 °C. equals 6.48.
