252 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



The only conclusion that one can fairly deduce from this particular 

 day, therefore, is that the skin temperatures of Squad B, after ap- 

 proximately two weeks of reduced diet, were not greatly unlike those 

 of the two normals with whom they were compared. 



On January 26, ten members of Squad A were studied. These men 

 had been on a reduced diet for approximately four months, and the 

 temperature measurements were made under exactly the same con- 

 ditions as those for the test with Squad B on January 19, namely, in 

 the library immediately after the hour of the group psychological 

 tests. The room temperature was 22.8° C. Considering the measure- 

 ments on the right and left hands first, we find no pronounced differ- 

 ence between the two hands as measurements differing by over 1.5° C. 

 are found in no instance with any member of the squad. On this 

 particular evening we fortunately had four normals for control, and 

 hence can speak more confidently of the comparison with the normal 

 individuals. The average temperature for the right hand found with 

 ten members of the squad was 29.09° C. With the normals the average 

 was somewhat higher, i. e., 31.17° C. With the left hand similar 

 average figures were obtained, being 28.83° C. for Squad A and 31.03° C. 

 for the normals. The very low values found for a few men of Squad 

 A should be noted, namely, those with Bro, Kon, Moy, Pec, Tom, and 

 Vea, all values very perceptibly lower than the normal values. Thus, 

 though the evidence is strongly against any unilateral temperature 

 condition, there is positive evidence that with certain members of 

 this squad the skin temperature on the backs of the hands was con- 

 siderably lower than that of normal individuals. 



The forehead temperature ranged from a minimum of 31.53° C. 

 with Pea to a maximum of 33.28° C. with Gar — a very small range. 

 The average, however, for the entire squad, namely, 32.58° C, is per- 

 ceptibly lower than the average of 34.03° C. for the four controls, 

 thus indicating that with Squad A not only the surface of the hands 

 but likewise the forehead had a measurably lower temperature than 

 was found in the same locations with the control men. 



On January 27 a second series of records for Squad B was obtained. 

 By desire of the subjects, the temperature of the room was unus- 

 ually high, being 27.3° C, but all the men, including the four con- 

 trols, were subjected to the same temperature for the same length 

 of time. The hand temperatures again indicate close agreement 

 between the right and left hand, with no temperature difference 

 greater than 1.5° C. The average value for the right hand for the 

 squad of 12 men was 32.50° C, while the average for the 4 controls 

 was 33.41° C. With the left hand the average value was 32.42° C. 

 and with the controls 33.30° C. The temperature of the forehead was 

 perceptibly higher than in the earlier observations on January 19, this 

 being due, in all probability, to the higher room temperature on
