 days are grouped separately, and the two series of experiments are 

 treated separately. For convenience the letters A, B, and C, repre- 

 senting the points under consideration, are used in the tabular form.

days Subject VI preceded these by voluntary lid movements. The 

 second reflex was not complicated by the voluntary lid movements to 

 such a degree. It was the usual thing for the subject to wink volun- 

 tarily some time after the two reflexes. The voluntary lid movements 

 are less conspicuous in the second series of experiments than in those of
