amounting to about one respiration more every two minutes, is so 
small that, were it not for the simultaneous and better defined excess 
in pulse-rate, it could be disregarded. As it is, it is probably an 
expression of correlated action of the lungs and the heart.

The numerical relation of the pulse-beats to respiration averages 
4.13, which is practically the same as in whites. 
In regard to age, the youngest adults of the series examined show 
(see table on page 27) a slightly greater average (+ 0.4 per minute) 
than the oldest ones. A similar condition was observed by the 
writer in the Indians and it also exists in the whites. As a result 
of this and of the frequently observed more rapid pulse in old age, 
the pulse-beat: respiration ratio is slightly higher in senility than 
earlier in adult life. 
As to stature, the shortest healthy men up to 50 years of age gave 
a lower average by nearly one breath a minute than the taller ones 
(for details see table on page 28). This stands again in correlation 
with the lower average pulse in those of short stature, but it is not 
possible to say whether the condition is characteristic of the people 
of the Oasis, or is merely an accidental feature of this group. How 
far it may be true of other ethnic groups is as yet uncertain. 
The pulse-respiration ratio in the two groups remains almost iden- 
tical (4.18 for the short, 4.16 for the tall), showing that there has 
been a harmonious response in this line of the two functions. 
A similar condition to that in the shortest adult prevails also in 
those who are weakest muscularly the series give a perceptibly 
lower average rate of respiration (as they did of pulse-rate) than 
that of the strongest individuals (see details in table on page 28). 
The difference of the averages amounts to 0.7 of a respiration per 
minute in favor of the strongest. The rate in the latter is also
