51. Fig. 51 is from a man aged fifty-five years; cardio-dorsalis pedis interval averaging one-tenth second ; arterial distance 51 inches ; velocity of pulse-wave 510 inches per second. The fact that pulse-wave velocity increases with age, thus so thoroughly established, signals indeed a range of varia- tion the widest that will be noted in all our results. What now is the cause of this marked variation with age ? Relating to the question as between the child and adult, there are four points tha...t claim to be noticed, viz., feebler pulse-waves ; smaller arteries ; lower blood pressure ; and thinner arterial coats, in the child. In the light of our experiments with tubes (i) feebler waves would have no modifying effect on pulse transmis- sion ; (2) smaller arteries would increase the rate ; (3) lower Digitized by VjOOQ IC io6 SPHYGMOGRAPHY. blood pressure would tend to diminish the rate ; and (4) thinner arterial coats would decidedly slow the velocity of the pulse-wave. Of these factors of modification, it would seem to be just to consider the smaller arteries and lower blood pressure as about counterbalancing each other, and then the thinner arterial coats would be left by the pro- cess of exclusion as the efficient cause of the pulse retar- dation in young children.
