highest vaginal temperature obtained was 101.8 0 at 8.10 a. tn., while 
the lowest was 101.2 0 at 8.54 a. m. and at 10 a. m. 
OBSERVATIONS ON DECEMBER 4 . I 9 I 9 > WITH COW 886 
Observations on the rectal and vaginal temperatures were made at 
approximately i-hour intervals from 7-45 a - 5- 2 4 P- The rectal 
and vaginal temperatures were measured simultaneously with the two 
thermometers, as on the preceding day. At 8.05 a. m. the cow drank 
9 kgm. of water at 54 0 F. During the readings at 8.57 a. m. and 2.24 
p. m. the cow was lying, while during all others she was standing. At 
9.33 a. m. the reading was taken immediately after defecation. From 
5 p. m. to 5.24 p. m. the cow was eating. The results are represented 
by figure 4. 
The curves show the usual fall in temperature after watering and the 
rise in the afternoon. The vaginal curve is lower than the rectal, meet¬ 
ing the latter at only one point, at 3.30 p. m. 
The highest rectal temperature obtained was 102.2 0 F. at 4.24 p. m. 
and 5.24 p. m., while the lowest was 101.6 0 from 10.42 a. m. to 2.24 p. m.

7.45 a. m. to 8.24 a. m. standing; 8.05 a. m. drank 9 kgm. of water at 54° F.; 8.57 a. m. lying; 9.33 
a. m. immediately after getting up and defecating; 10.42 a. m. to 1.30 p. m. standing; 2.24 p. m. lying; 
3.30 p. m. to 5.24 p. m. standing; 5 p. m. to 5.24 p. m. eating. 
The highest vaginal temperature obtained was ioi.8° at 4.24 p. m. and 
5.24 p. m., while the lowest was 101.2 0 from 8.57 a. m. to 11.30 a. m. 
OBSERVATIONS ON DECEMBER 5 , 1919, WITH COW 886 
Observations on the rectal and vaginal temperatures were made at 
approximately i-hour intervals from 7.45 a. m. to 11.24 a. m. and from 
1.36 p. m. to 5.24 p. m. The rectal and vaginal temperatures were 
measured at the same time with the two thermometers as on Decem¬ 
ber 2 (fig. 2). At 8 a. m. the cow drank 6 kgm. of water at 54 0 F. At 
7.45 a. m., 9.42 a. m., 11.24 a - m -> an( * 1*36 P- ni. the cow was lying; 
during the other readings she was standing. At 10.36 a. m. and at 3.18 
p. m. the readings were taken immediately after defecation. From 5 
p. m. to 5.24 p. m. the cow was eating. The results are represented by 
figure 5.
