occurs 0*45 to 0*52 to 0'59 sec. after the beginning of the curve. It varies with the height of 

 the individual. 



2. The dicrotic elevation in the descent is lower, and is less distinct, the further 

 the artery is situated from the heart, so that the longer the distance which the 

 wave has to travel the less distinct it becomes. 



3. It *is best marked in a pulse where the primary pulse-wave is short and
