Pulse and Respiration. 115 The effect of alcohol upon the pulse rate of Subject VI is also indi- cated in table 20 by the statistical method of differences. The average differences given in the last column of the table show that on the normal days the average difference is always a plus value. These average differences for the seven experimental conditions are, for the normal days, +11, +54, +78, +77, +25, +50, and +44. The comparison values for the alcohol days are always minus, being —37, —107, —77, — 83, —53, —52, and —87. The general averag

The comparison values for the alcohol days are always minus, being —37, —107, —77, — 83, —53, —52, and —87. The general average differences for these two series are, respectively, +48 and —71. What is thus indicated by the average differences will likewise be found to be true for the indi- vidual periods 2, 3, 4, 5, and 6 for the pulse taken under the different conditions from 1 to 7; that is, the differences for normal days have usually the plus sign, while those for alcohol days are usually minus.

The effect of alcohol is found by deducting the normal difference from the alcohol difference. These results are given for each of the seven experimental conditions in table 20, and are also stated in terms of per cent. They are likewise summarized in table 21, which shows by periods the average effect of alcohol for each of the conditions. There are only two values in the latter table which are preceded by the plus.
