NO. I NATIVES OF KHARGA OASIS HRDLICKA 29 
In relation to stature, the temperature is on the average higher 
in the " tallest " than it is in the " shortest " Kharga natives. And 
the temperature goes hand in hand in these groups with both pulse 
and respiration. The " shortest " males at the Oasis show thus on 
the average a somewhat less active metabolism, as well as a slower 
heart and slower respiration. They manifest lesser vitality, which 
suggests a causal relation between at least some of the low statures 
at the Oasis and the agencies which condition lowered vitality. 
The main of these conditions are probably chronic malnutrition, and 
protracted effects during the developmental stage of life of malaria 
or other systemic disorders. The tallest Kharga men are, on the 
average, of a distinctly superior vitality. 
Muscular potency shows similar relation to temperature as age 
and stature : It is in general perceptibly below the average in those 
who give low temperature, and both go together with sub-average 
pulse rate as well as respiration-rate. The individuals of the best 
muscular vigor show mean temperature, with slightly sub-average 
pulse, but somewhat above average respiration. A larger series of 
observations would in these respects be very desirable. 
MUSCULAR STRENGTH 
The tests of muscular strength were those of pressure in each hand 
and traction. 1 They were made by Mathieu's dynamometer and repre- 
sent the maximum exertion of the subjects determined in two to 
four consecutive trials. The hands and arms were in every case 
held free from the body and cases with crippled or sore fingers, 
hands or arms were excluded. There was no unwillingness or lack 
of interest on the part of those examined in making the tests, so that 
the record obtained may be regarded as fairly representative of the 
true condition in regard to muscular strength of the Kharga men. 
The results are seen in the following tables.

its small end and the arms held not higher than the chin.
