blank was so made up. In table 147, the scores range from 0.6 to 

 10.8. The total average is approximately 5. The individual differ- 

 ences may be seen in the averages in the bottom line of the table. 

 Each value is from the nine low-diet results in the column above. 

 As September 29 was normal, it is never averaged with the other 

 dates. The average at the bottom of the table covers the low-diet 

 period and for convenience is called low-diet average. Tom, Bro, 

 and Vea made the best scores. The values were: 2.0, 2.2, and 2.3. 

 Tom was very consistent throughout. He made decidedly the best 

 records in the early sessions, but did not keep his lead owing, no doubt, 

 to his physical condition as a result of the operation which came near 

 the end of the experiment. The scores of Pea may have been affected 

 by the fact that a few hours before he came to Boston he usually 

 engaged in a cross-country race. It may be of significance that when 

 Kon showed the poor score of 10.8, he was practically fasting. 



In table 148, which gives the results for Squad B, the range of varia- 

 tion is about the same, that is, from 0.6 to 11.7. The upper 5 dates

at the left hand of the table were normal ; the 3 lower ones were during 

 food reduction. The two groups of records have been averaged separ- 

 ately for each individual. The best records were made by Sne, How, 

 and Tho. The low-diet averages for each individual, with the excep- 

 tion of a few cases, show that during the low diet the subjects continued 

 to improve in the test, with the result that they made fewer errors. 

 This was not the case with Har, who had a normal average of 3.7 and 

 a low-diet average of 5.1, and Liv, who averaged 3.5 under both condi- 

 tions. The average score for both groups of men. Squads A and B, 

 is, if anything, a little smaller than the scores reported by Fisher and
