The author took the rectal temperatures of 3 cows and 2 goats in good health and not pregnant for 2 consecutive days, running every 1.5 hours, and investigated their periodical changes during a day. The results of observation may be summarized as follows: (1) The normal, rectal temperature of the cows ranged from 37.5° to 39, 1℃ and that of the goats from 38.15℃ to 40.4℃. (2) The daily changes in the individual cows ranged from 0.65° to 1.6℃ and in the goats from 1.05° to 1.8℃. (3) The time which presented the lowest body temperature during a day was different for each individual and for each day, but in most cases it was observed at sometime between 6 and 9 a.m. On the contrary, the highest temperature during a day was always observed at 4.30 p.m. except 1 case in the cows.
