In a progression almost the exact opposite of that observed in Experiment 1, the original parent leaves of Experiment 2 continue to die.  In the two bottles with the highest airspace CO2 concentrations (Bottles 5 and 6), both of the two original leaves are completely dead.  In Bottle 4, one of the original leaves is completely dead, as is 80% of the second one.  Only 60% of one leaf has died in Bottle 3, however; and but a tenth of one leaf has expired in Bottle 2.  And in Bottle 1, both of the original parent leaves look as healthy as the day the experiment began!
