The curves show, in general, a slight and gradual drop. It should be 
noted that the initial temperature—that is, the temperature at 5 p. m.— 
was rather high.

Fig. 16.—Variations in body temperature of cow 886 on December io, 1919, 5 p. m. to 6.30 p. m. From j 
p. m. to 5.36 p. m. eating; 5 p. m. immediately after defecating; 6.03 p. m. to 6. 30 p. m. lying. 
OBSERVATIONS ON DECEMBER II, 1919, WITH COW 886 
Readings of the rectal and vaginal temperatures were taken at approxi¬ 
mately 15-minute intervals from 4.52 p. m. to 6.36 p. m. From 5 p. m. 
to 5.48 p. m. the cow was eating. From 6.21 p. m. to 6.36 p. in. she 
was lying. The results are represented by figure 17. 
Fig. 17.—Variations in body temperature of cow 886 on December n, 1919. 4-5* P- “a* to 6.36 P- m. From 
5 p. m. to 5.48 p. m. eating; 6.21 p. m. to 6.36 p. m. lying. 
The curves show a gradual rise in temperature till 5.30 p. m., followed 
by a fall which is continuous in the vaginal temperature but is inter¬ 
rupted by a very slight rise in the rectal temperature at 6.21 p. m., the 
time the cow lay down. The two curves are nearly parallel.

OBSERVATIONS ON DECEMBER 1 3, 1919, WITH COW 886 
Observations on the rectal temperature were made at about 15-minute 
intervals from 5 p. m. to 6.57 p. m. From 5 p. m. to 5.30 p. m. the cow 
was eating. From 6.15 p. m. to 6. 57 p. m. she was lying. The results 
are given in figure 18.
