of the conditions that relate initial depression of the performance to 

 decreased fatigue, one must be cautious about ascribing this decreased 

 fatigue after alcohol directly to the alcohol. But it is a rather sug- 

 gestive fact that the decreased fatigability after dose A changes a 

 depression of the phenomenon at the end of the first 2" to an equally 

 good performance at the end of 6". If one might venture a prelimi- 

 nary hypothesis, it looks as though the effect of alcohol on the reciprocal

innervation of the finger was analogous to its action on the reflexes. 

 With a depressed initial performance after alcohol the relative fatigue 

 in subsequent performances is lessened. The summary of average dif- 

 ferences confirms this general relationship. 



Summaries of the effect of alcohol on the reciprocal innervation of 

 the finger are given in tables 32 and 33. Table 32 is calculated from the
