The following appears from the above : That there is 

 a curve of temperature ; that the maximum differs from 

 the minimum (in this case 102-4°, 100-4°, 102-2°, 100-5°) 

 to the extent of about 2° — quite an important matter in 

 determining the temperature range in fever. 



While there is a maximum in every case examined, it 

 has been found that the hour has not agreed in any of the 

 dogs examined, though kept under the same conditions. 

 The individual differences in temperature, like the indi- 

 viduality of animals generally, have been somewhat 

 ignored by writers on science and medicine. 



The rectal temperature very rarely falls below 100°, 

 and it is important to note that it may rise, as the author 

 has many observations to show, above 102° considerably ; 

 so that a conclusion that fever exists can not be made on a 

 reading of even 102*8°, especially in a puppy in which the 

 temperature may naturally be higher than in an adult 

 dog, and is liable, as in human infants, to oscilla^te very 

 rapidly.
