From this diagram it is certainthat the relations shown in figure 12 are not due to the fact that any oneday exercises a predominating influence upon the shape of the we selected anyone of the alcohol days and anyone of the normal days 104 Effect of Alcohol on Psycho-Physiological Functions. and plotted the two curves, the form and relationship of the curveswould be substantially like those of the curves in figure 12. The question which must be answered next concerns the first periodfor the alcohol days. As the results are obtained before the alcohol istaken, the data are normal, i. e., uninfluenced by alcohol. The naturalquery would be: Are the changes in pulse rate during the first period ofalcohol days different from the changes during the first period of normaldays? The answer to this question will be found in figure 14. Here, as. 65432 I I 2345671 23456789 10 12 14 16 18 20 Fig. 14.—Duration of pulse cycles given in hundredths of » second in first, second, and thirdperiods on normal and alcohol days in pre-tetanus, tetanus, and post-tetanus divisions. in the preceding figure, light and heavy lines have been used to repre-sent the data for alcohol and non-alcohol days, respectively. To sim-plify the figure only 6 curves are incorporated, these representing theaverages for periods 1, 2, and 3 of the alcohol days and the same periodsfor the non-alcohol days. The two continuous-line curves, one lightand the other heavy, for the first periods of the alcohol and normaldays, respectively, both represent normal data, since in each case therecords were taken preceding control or alcohol doses; these normalcurves must be given the first attention. In the pre-tetanus sectionthese curves lie very close together—closer in fact than any other twocurves of the six. Th
