as the second length of artery was flattened. Finally, the first piece of artery 

 was deformed by the increase of compression and gave its maximal swing. 

 The excursion of this maximal swing, owing to the increased diastolic pressure, 

 was smaller, and the pressure at which it occurred higher, than was the case 

 when this length of artery was compressed by itself.
