On the average for the 3 days, November 4, 18, and December 16, 

 the men of Squad B have average eye movement time which, in the 

 case of movements left, ranges from 88.0 to 117.5 <t, Sne and Fis. 

 The average for all is 96.3 <r, the average variability 8.3 per cent. In 

 the case of movements right the range is from 81.7 to 104.5 a for How 

 and Fis, respectively. The average for the 10 subjects usually dis- 

 cussed is 89.3 (T, the variabihty 8.6 per cent. Thus the members of 

 Squad B show no values which are on the one hand as small, or on the 

 other as large, as the limiting ranges of the group of 1917.
