140 INJUEY, RECOVERY, AND DEATH 



In the preceding pages a theory is developed which 

 enables us to predict the behavior of Laminaria when 

 transferred from sea water to certain solutions, e.g., NaCl

Fio. 69. — Curves showing the net electrical resiatance of Laminaria agardhii in 0.52 M 

 NaCl, in 0.278 M CaCh, and in mixtures of these (the figures attached to the curves show 

 the molecular per ocnt. of CaCh in the solution). The curves show the calculated values 

 (from constants obtained by trial) which are given in Table X, the points show the observed 

 values (some are omitted in order to avoid undue crowding) ; each represents the average of 

 six or more experiments. Probable error of the mean less than 10% of the mean. 



0.52 M and CaCla 0.278 M. If the theory is sound it 

 should also enable us to predict the behavior of the 

 tissue in mixtures of these solutions. 



In order to test this theory experiments were made 

 with a variety of mixtures. The solutions employed are
