In the next two experiments the amplitude and rate of the 
respiratory excursions of the tambour-lever is placed opposite the 
numbers representing the arterial pressure at the time being. 
From these it will be seen that the fall in blood pressure is not 
in any way dependent upon diminished respiratory efficiency.
