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 perceptibly 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 unusually high, being 27.3° C, but all the men, including the four controls, 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 January 27. With the 12 men the values ranged from 33.59° C. to 35.00° C. The 4 control men gave values averaging 34.55° C, while the average for the 12 men was essentially the same, 34.43° C.

On February 2 the last series of skin-temperature measurements was obtained with Squad A. Here again we find a number of distinctly low measurements for the surface of the hand, these occurring with Moy, Tom, and Vea. With Pec the temperature of the left hand was perceptibly lower than that of the right. These readings were very carefully checked several times to determine beyond question this pronounced difference. We are unable to explain it. Personal statements of a member of Pec's family to the effect that one side of his body seemed to be much colder than the other might be considered of significance here were it not for the fact that in the study made of this man on January 26, although the surface temperatures of both hands were low, they agreed with each other to within 0.38° C. The average value for the right hand with Squad A on February 2 was 32.04° C, which was perceptibly lower than the average found with 6 controls (33.10° C). The room temperature on this date was 25.2° C.

The forehead temperatures for Squad A on the same day ranged from a minimum of 33.46° C. to a maximum of 34.79° C, the average value being 34.20° C. As a matter of fact, this average value is slightly higher than the average forehead temperature of 34.09° C. found for the 6 controls.

Giving full recognition to the paucity of normals and the difficulty of obtaining accurate skin temperatures, we find that an analysis of the foregoing data does not indicate uniformly lower surface temperatures for most of the men. With certain members of the two squads, the skin temperature as measured on the back of the hands was definitely lower than the normal values. In one or two instances, at least, low temperatures for the surface of the hand were observed with considerable regularity, these men being those who apparently suffered most from cold hands. Thus Vea, of Squad A, frequently complained of cold hands, and on the two days when his surface temperature was measured values lower than normal were found. On January 26 his values were higher than the average for the whole group, but on February 2 they were lower than the values obtained for any other man in Squad A except for the right-hand temperature of Tom. With Bro very low values were found on January 26, while values slightly higher than normal were found on February 2. With Tom a low value was found for both days. Pec, with the single exception of the right-hand measurement on February 2, also gave a low record. With the forehead temperatures the variations from normal show no material uniformity.
