regards courts-martial and their results, the differences between the two 

 types are immaterial. The numbers of trials are identical, the blonds 

 had an average of 0.3 day more of confinement, but the brunettes 

 received an average of 0.48 dollar more fines. The classifications of 

 the two types according to military character agree as closely as could 

 be expected in groups of this size. As regards change of character an 

 equal proportion of each type underwent no alteration, but of the 16 

 blonds and 15 brunettes whose character did change, 12 of the blonds 

 deteriorated as compared with 8 of the brunettes. However, the number 

 who changed is so small that it would be unsafe to make deductions 

 therefrom. 



In Table XXVII it will be seen that the number of abstainers was 

 practically the same in both types and that the blonds had a larger 

 number of slight drinkers and fewer moderate ones. The number of 

 excessive drinkers was greater among the blonds than among the bru- 

 nettes (13 as compared with 9) . There were 18 /admissions for alcoholism 

 and 62 days lost among the blonds as compared with 6 admissions and 

 31 days lost among the brunettes. The days on sick report from venereal 

 diseases were practically equal for the two complexion types. 



SUMMARY OF PART VI. 



In summing up it can be said that there was no appreciable difference 

 in behavior between the blonds and the brunettes except in regard to 

 stimulants, the excessive use of alcohol being somewhat more common 

 among the blonds. However, too much weight should not be given to 

 this last conclusion in view of the small numbers of persons who indulged 

 to excess. 



PART VII. RELATIVE EREQUENCY OF OCCURRENCE OE SUNSTROKE AMONG 

 BLONDS AND BRUNETTES IN THE UNITED STATES. 



The exact causation of sunstroke and heat exhaustion remains in doubt 

 in spite of the many theories advanced by eminent observers. Among 

 these theories may be mentioned that advocated by Maude of the British 

 Army, who considered that sunstroke was due to the action, upon the 

 head, of the actinic rays of the solar spectrum and believed that insolation 

 could be prevented by inserting in the headdress a layer of material 

 impervious to these rays. He employed a red hat lining. In connec- 

 tion^ with OUT Avork on the influence of climate on blonds and brunettes 

 it was desired to obtain statistics as to the complexion type of men suf- 

 fering from insolation. Such figures could not be obtained in the 

 Philippines, because heat exhaustion is rare and time sunstroke prac- 

 tically unknown in the Archipelago. Therefore, statistics were gathered 

 from the large cities in the United States through the courtesy of the
