INFLUENCE OF PHILIPPINE CLIMATE ON WHITE MEN. 449 



(27 per mille), but was a great deal higher still for the mixed types 

 (60 per mille). In the 1910-Groiip the rate was also higher for the 

 blonds, but the difference was less marked than in the S-C-P-Gronp, 

 50 as compared with 44 per mille. In considering the figures for the 

 S-C-P-G-roup it must be borne in mind that the total number of eases 

 was very small, only 7 for the blonds and 4 for the brunettes, so the 

 element of chance may assume very large proportions. 



Enjoyment of tropical service.— In the 1910-Group there was no 

 material difference, the rates of those who did not enjoy such service 

 being 381 for the blonds and 375 for the brunettes. In the S-C-P-Group 

 the difference was more marked, 65 per mille of the blonds not enjojdng 

 the Tropics as compared with 54 per mille of the brunettes. However 

 the number of men from the mixed type who did not like such service 

 was far higher than among the blonds, 115 per 1,000. That a much 

 greater proportion of the 1910-Group, as compared with the S-C-P- 

 Group, should dislike the service is natural when it is recalled that the 

 former were enlisted men serving in the Philippines largely from necessity, 

 while the latter were officers and policemen who had elected to reside 

 in the Archipelago, in most cases after having had some preliminary 

 experience with its climate. 



Feeling of well-being in the Tropics. — The proportion of soldiers in 

 the 1910-Group who did not feel as well in the Philippines as at home- 

 showed no material variation for the blonds and for the brunettes, 245 

 per mille for the fair and 241 for the dark complexioned. In the 

 S-C-P-Group the difference was much more marked, 145 per 1,000 of 

 the blonds not feeling as well as in America and only 109 per 1,000 

 of the brunettes. But here again the mixed types suffered more severely 

 than the blonds, 174 per mille of them failing to feel as well as in the 

 homeland. In the 1910-Group the number of blonds who felt better 

 than in America was larger than the corresponding number of brunettes 

 (43 as compared with 35 per mille), but in the S-C-P-Group the condi- 

 tions were reversed, 109 jjer 1,000 of the brunettes feeling better as 

 compared with only 65 per 1,000 of the blonds. However, the actual 

 numbers of men in this class were small in both groups. The numbers 

 who felt the same here as at home were practically equal for the blonds 

 and for the brunettes in the S-C-P-Group and in the 1910-Group. 



With reference to the special symptoms complained of, the actual 

 figures can best be seen in Table XXIII, and it will be sufficient to state 

 here that in the S-C-P-Group the incidence of insomnia, anorexia, sore 

 eyes, and loss of memory was considerably more marked for the blonds 

 while in the 1910-Group the reverse was the case for all except eye 

 troubles. In both groups indigestion, palpitation of the heart, and 

 diarrhoea were more common among the brunettes. It is interesting to
