Fig. 1. Curves showing the electrical resistance of Laminaria agardhii in 

 0.52 M NaCl, in 0.278 M CaClo, and in mixtures of these (the figures attached to 

 the curves show the molecular per cent of CaClo in the solution). The curves 

 show the calculated values (from constants obtained by trial, which are given in 

 Table II) ; the points show the observed values (some are omitted in order to avoid 

 undue crowding) ; each represents the average of six or more experiments. Prob- 

 able error of the mean less than 10 per cent of the mean.
