Contents: Necessity of cellular physiological analysis of toxic depres- 

 sions by pharmacology. Apparent variety of processes of depres- 

 sion. Depression of oxydative disintegration as the most extended 

 principle in the processes of depression. Asphyxiation, fatigue, 



heat depression, as a consequence of restriction of oxydative dis- 

 integration. Narcosis. Theories of narcosis. The alteration of 

 specific irritability and conductivity in narcosis. Depression of 

 oxydative processes in narcosis. Asphyxiation of living substance 

 when oxygen is present during narcosis. Persistence of anoxyda- 

 tive disintegration in narcosis. Increase of the same by stimuli. 

 Depression by narcosis as a form of acute asphyxiation. Hypothe- 

 sis on the mechanism of depression of oxygen exchange by nar- 

 cotics. Possibility of combining the facts with the observations of
