tion of the records* shows the avera.s^e daily variation of 20 ani- 

 mals in which the temperature was taken for 24 hours to be 

 2.31° F. The maximum individual variation in a single day 

 was 4. 3° F. , the minimum 0.5° F. In 25 other animals where the 

 temperature was taken for 16 hours, the average variation was 

 1.79° F. In these the maximum variation was 3,2° F., the 

 minimum 0.6° F. Ten healthy animals (did not react to 

 tuberculin) in the same herd gave an average variation of 

 2.08° F. In these the maximum dailj' variation was 4.1° F., 

 the minimum 1° F. The lowest temperature was usually, but 

 not invariably, in the morning and the highest in the after- 

 noon or evening. I have appended the records of the temper- 

 ature of two of these animals.
