Fit;. 6. — Specimen records of lid reflex of Subject VI. 



A normal record for Subject VI commonly shows voluntary winking before or after the 



reflexes. 

 Second reflex is small in amplitude as it falls within the refractory period. 

 Four hours after taking dose. The amplitude is large and voluntary winking present as 



normally. 

 A voluntary wink followed the second reflex. 



The amplitude of the broken curve signifies that lid-closure is usually only partial. 

 The voluntary and reflex closures together form a nearly regular curve. See also, second 



reflex of A: such a record can not be read with accuracy. 

 50 minutes after dose. Marked decrease in amplitude and voluntary winkiiii.'.
