INJURY, RECOVERY, 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 declrical 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 15°C., 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 caU K^) by the usual formula:^* 



If we make this calculation, employing for this pur- 



" Common logarithms are used for convenience. We put a = 100 — 10 

 and » ^=^ 5C = if — 10.
