TEMPEBATUKE AND ITS CONDITIONS 335 



ditions living substance ceases to carry out the normal 

 reactions which are characteristic of it so long as it is what 

 we call ' living,' and that the power to resume them after 

 the disappearance of the adverse conditions is not regained 

 by it. The nature of life and the intimate causes and 

 features of death are still beyond our knowledge.
