At one or more of the quarterly periods there were found among 

 the men of both types some eases of elevation of temperature without 

 assignable cause, but it will be obvious on examining the tables that 

 these occurrences were not sufficiently numerous to raise the average 

 temperature for the year materially above the recognized normal for 

 temperate climates. The average temperature for the blonds at no 

 quarterly period varied more than 0°.l F. (0°.06 C.) from the correspond- 

 ing figure for the brunettes, sometimes one type and sometimes the other 

 showing the higher figure. For the whole year the average for the two 

 types was the same for the 1910-G-roup and but 0°.l F. (0°.06 C.) 

 different in the 1909-Grroup. Therefore, it was concluded that as re- 

 gards the maintenance of bodily temperature in the Tropics there were 

 no constant differences between the blond and the brunette types. 



Pulse and respiration. — The pulse and respiration were taken as a 

 rule with the men seated. At the few posts where the record was made 

 with the men standing the numbers of blonds and brunettes were ap- 

 proximately equal so the relative influence of this factor is the same for 

 the two complexion types. The results are shown in Tables IX and X.
