FIG. 23. Curves of net, electrical resistance of Laminaria agardhii in sea water containing 



various amounts of HC1. The ordinates represent net resistance. The abscissse represent 



concentrations of HC1. All readings are taken at 18 C. or corrected to this temperature. 



Each curve represents a single typical experiment. 



In the previous experiments with alkali 22 it was found
