Av. diastole 556<r; M. V. 63<r. Av. diastole 639(r; M. V. 680-. Av. diastole 7sl<r; RI. V. 77 a. 



Similarly the normal of the day on the alcohol day showed about the 

 same percentile mean variation: 



Av. diastole 407 a; M. V. 42(7. 



After alcohol, however, the mean variation dropped to 5 per cent 

 and less: 



Av. diastole 514<r; M. V. 23<r. Av. diastole 543cr; M. V. 20<r.

Bracketed normal mean variations had no corresponding alcohol measurements and are conse- 

 quently excluded from the averages.
