The former shows a decreased amplitude in periods 2, 3,and 4, and the greatest decrease at 5, where the latency (fig. 2) was theshortest, with a change to slightly plus at period 6. For A, 50 grams,we find an increased amplitude in periods 2 and 3, changing to a de-crease more marked in degree in 4 and 5, and again to an increase inperiod 6. The increased amplitude with the 50-gram stimulus inperiods 2 and 3 might easily result if the alcohol produced a greater 46 Effect of Alcohol on Psycho-Physiological Functions.
