This table does not indicate as high a rate of infestation for blonds 

 as for brunettes except with ascaris and cercomonas, which have little if 

 any significance. The rate of hookworm infestation was slightly greater 

 for the brunettes. This work confirms the previous observations of the 

 writer (16) as to the infrequent occurrence of uncinariasis among Amer- 

 ican soldiers serving in the Philippines. 



Special ohservations after exercise. — These examinations were made on 

 the 1910-Group, once near the beginning and once near the end of the 

 year of observation, with a view to determining whether the blonds became 

 more easily exhausted by physical exertion than did the brunettes. The 

 exercise preceding the examination was usually a- practice march or a 

 period of drilling, and was as nearly as possible the same for the two 

 complexion types. The results are tabulated in the following table. 

 For each kind of observation the time was the second quarter of the 

 year, the first being in 1910 and the second in 1911.

" The weights are the average for 169 blonds and 158 brunettes and the blood-pressures 

 for 136 blonds and 124 brunettes. 



On comparing this table with the preceding ones, which show the 

 same class of observations when the men had not exercised, it is seen 

 that as a result of the exertion there was a small average loss in weight, 

 approximately 1 pound (0.5 kilogram), and a slight average increase in 

 respiration rate and temperature, the increase of the former approximating 

 two inspirations per minute and the latter 0°.l C. The pulse rate was 

 accelerated considerably, ranging from 5 to 10 beats per minute in excess 

 of the rate when the men were at rest, and the systolic blood-pressure
