190 INJUEY, RECOVERY, AND DEATH 



least recovery is incomplete) ; in the first experiments 

 this condition was unintentionally realized and led the 

 writer to suppose that alcohol behaves like ether. The 

 course of a typical experiment is shown in Pig. 83. The

c.c. of concentrated sea water. The mixture had the 

 conductivity of sea water; the concentration of the 

 alcohol was 0.051 M (2.96% by volume). The net resist- 

 ance rose to 110% in the course of 40 minutes. The tissue 

 was then placed in sea water containing 0.2385 M alcohol 

 (13.875% by volume) ; and in the course of 20 minutes the 

 resistance fell to 87.6%. The tissue was then placed in 

 sea water and the resistance again rose to 100%. 



The facts that recovery occurs in alcohol, and that 

 irregular fluctuations are often observed in experiments 

 on recovery from ether, suggest that the difference
