An examination of the foregoing experiments will show that in Experiment 2 alcohol had 

 no distinct effect upon the arterial pressure until it was given in such amounts as to reduce the 

 pressure. In Experiment 3, there was a rise of the arterial pressure, 18 millimeters, in the 

 course of about as many minutes. In Experiment 4, a rise of the arterial pressure of nearly 

 4<t millimeters was reached. These experiments seem to show that alcohol has a tendency to 

 produce a slight rise in the arterial pressure in the normal dog, but that this tendency is not 

 pronounced and may fail to occur, even when small and carefully calculated doses are employed.
