The reports from these persons cover an average of 5.5 years of con- 

 tinuous tropical service, the duration of Philippine residence for the 

 individuals ranging from two to thirteen years. In reply to our questions 

 as to illness a considerable proportion merely stated the number of times 

 they have been sick and the cause of the disability, without giving the 

 duration of the disease. Therefore Table XXII, which contains the data 

 collected, simply shows the number of attacks of each illness, but does 

 not give the days lost from sickness.

For convenience in comparing, the admissions to sick report have been 

 reduced to rates per 1,000 men of each type. First of all it is to be 

 noted that the proportion of those who had never been sick is much 

 higher for the blonds than it is for the brunettes. The total number 

 of admissions for all diseases was considerably higher for the brunettes 

 than for the blonds, 1,110 as compared with 902 per mille. Taking up 

 the individual diseases it will be seen that the brunettes had a higher 

 admission rate than the blonds for all diseases except dengue, cholera, 

 pneumonia, indigestion, skin diseases, and neurasthenia. In the last 

 disease the comparison is of no value since even among the blonds there 

 was only one admission. For many of the diseases the mixed types 

 showed a higher admission rate than did the blonds.
