Fig. 1. Curves showing the resistance of Laminaria in 1.1 M sodium acetate, 

 in 0.36 M sodium sulfate, and in mixtures of both: A in equal parts (by volume) 

 of acetate and sulfate; B in acetate 75, sulfate 25; C in acetate; D in acetate 

 25, sulfate 75; E in sulfate. Ordinates represent resistance (expressed as per 

 cent of the original resistance in sea water which is taken as 100 per cent). 

 Each point represents the average of ten experiments: probable error of the 

 mean less than 5 per cent.
