PULSE-RATE.

TABLE 17. Basal pulse-rate of boys at different ages. 



For the first 5 days after birth the number of infants is sufficiently 

 large to justify a study of the general trend of the pulse-rate during 

 this time. On the last 3 days the number is obviously too few, but 

 the results are included here to complete the data. From this table 

 it can be seen that there is a slight tendency for the pulse-rate to rise 

 and remain at the higher level after the first 3 days, with a tendency 

 to decrease successively on the first 3 days. All of these values are 

 measurably less than that reported for the last hours of fetal life.
