INJUEY, KECOVERY, AND DEATH 



death in this case just as a chemist follows the progress 

 of a reaction in vitro. This has also been found to be the 

 case in experiments with a great number of toxic sub- 

 stances and seems to be of very general applicability. 



TABLE I.* 



Net electrical resistance of Laminaria in NaCl 0.52 M. The resistance in sea 

 water (the normal environment) is taken as 100 per cent. 



* All readings were made at 15C., or corrected to this temperature. 



If we were unaware that the death curve in NaCl 0.52 

 M represented two consecutive reactions, and supposed 

 it to represent a simple monomolecular reaction (M > 

 jB), we should calculate its velocity constant (which we 

 may call K^) by the usual formula: 34 



If we make this calculation, employing for this pur- 



M Common logarithms are used for convenience, We put a = 100 10 

 Mid x = M 10,
