consecutive days are quite common, and greater ones are possible even 
under identical conditions. 
DAILY VARIATIONS IN BODY TEMPERATURE MEASURED AT 8 A. M., 1.30 
P. M., AND AT 9 A. M., RESPECTIVELY, FOR SEVERAL CONSECUTIVE 
DAYS 
It has been shown by the very first observations (fig. 1-10) what 
effect the water drunk under the conditions of the experiment has on 
OEC. 0/7/V.

the body temperature—that if water is drunk in considerable quantity 
the fall in temperature is very marked, and this effect may last more 
than three hours, but that after this effect is overcome the temperature

remains quite uniform for about the next three hours. It would there¬ 
fore perhaps be interesting to see a graphic representation of the tem¬ 
perature changes for several days when measured, first, before watering,

second, when the effect of the water has been overcome, and, third, 
about an hour after watering. Accordingly, the respective tempera¬ 
tures observed during the first few days of the experiment (fig. i-io), 
at 8 a. m., at 1.30 p. m., and at 9 a. m., are shown by figures 42 to 46. 
Figures 42 and 43 represent the temperatures of cow 886 at 8 a. m. 
and at 1.30 p. m., respectively, for December 1 to December 5, 1919.
