In Groups I and II the separation into complexion t5'pes was made 

 by the physicians at the various hospitals, our system of classification 

 having been furnished them. It will be noticed that they placed ex- 

 tremely few in the blond type, perhaps assigning to that class only the 

 most conspicuous examples of blondness. In Group III the physicians 

 were requested to fill out for every case of insolation a printed form 

 whieli contained among other things the following complexion- type table.

The physicians prepared one of these blanlc forms for every patient 

 suffering from insolation, and made a check-mark after the appropriate 

 word in each of the three columns of the complexion-type table. The 

 completed forms were then sent to us and, following the rule used in 

 our work among the soldiers, we classed as blonds those who had the 

 three check-marks above the dividing line, and as brunettes those where 

 all the check-marks were below the line. If some marks were above and 

 some below the man was placed in the class composed of mixed types. 



We received 229 of these cards and they are recorded in Table XXVIII 

 as Group III. There were 72 blonds, 70 brunettes, and 87 mixed types. 

 Eeduced to a percentage basis, for each 100 blonds there were 97 bru- 

 nettes. As shown in Table XXIV the proportions of blonds to brunettes 

 among our 10,072 soldiers was as 100 to 86. Therefore, it is clear that 

 the ratio of brunettes suffering from the effects of the sun in the United 

 States was materially higher than the ratio of the same type among 

 10,078 American soldiers.
