INFLUENCE OF PHILIPPINE CLIMATE ON WHITE MEN. 447 



SUIIMARY OF PAKT HI. 



The evidence adduced in this section is conflicting. While sickness 

 was considerably more common among the blonds in the soldier group 

 the reverse is true in the S-C-P-Group. Furthermore, in the latter 

 group the proportion who had never been sick was materially larger 

 among the blonds than among the brunettes. While the statistics were 

 more complete and the number of men considered was much larger for 

 the soldier group, it should be remembered that the period of time spent 

 in the Philippines, and covered by the sick record, was much' longer for the 

 S-C-P-Group. Therefore, no conclusion pointing clearly in one direc- 

 tion or the other can be drawn from the statistics compiled in Part III. 

 Of the 31 medical officers who observed the men of the 1910-Group, only 

 one could note any difference in the two types and this officer, Lieutenant 

 Mueller, was of the opinion that the blonds had "suffered from tropical 

 influences somewhat more than the brunettes." He suggested that psy- 

 chological tests might show deterioration that was not indicated by phys- 

 ical examinations. Unfortunately it was impracticable to make such 

 observations. 



PART IV. SYMPTOMATOLOGY AND DIETARY HABITS FOR THE 1910-GROUP AND 

 EOR THE SCOTJT-CONSTABULARY-POLICE-GROUP. 



The information dealt with in this part was obtained in the case of 

 the 1910-Group by questions addressed by the medical officers conducting 

 the observations. To each member of the S-C-P-Group a blank form 

 was sent with a request that the printed questions thereon be answered.^^ 

 In setting a value on the following data,, it must be remembered that we 

 are dealing mainly with sensations and not with physical signs, and that 

 in case of both officers and men it was well understood why the questions 

 were being asked. The topic of the relative endurance of blonds and 

 brunettes has received not a little popular discussion in the Archipelago, 

 and, therefore, one must consider the possibility that some answers were 

 unconsciously influenced by what the speaker or writei' thought should take 

 place. 



The individual members of the S-C-P-Group had had continuous 

 tropical service for periods ranging from two to thirteen years, the average 

 being about 5.5 years. For the blonds it was 5.1 years, for the brunettes 

 5.5 years and for the mixed types 5.6 years. The average Philippine 

 service for the 1910-Group was 18.5 months at the time the questions 

 were asked. The numbers of answers to each question for each com- 

 plexion type have been reduced to rates per 1,000 of that type in order 

 to facilitate comparison. The replies are shown in Table XXIII, and 

 will be discussed under several subheads. 



" The data from the Constabulary and the Police were obtained through the 

 courtesy of the Director of the Philippines Constabulary and the chief of the 

 Manila police.
