F.] ; only exceptionally, in tetanus, contagious pleuropneu- 

 monia, and influenza, is this high mark passed. The highest 

 temperature is carried by fowls, namely 43,5° C. [110,3° F.]. 

 [In cases of "heat stroke" in horses hyperpyretic temperature 

 may reach 110° F.]. 



During a single day a febrile temperature does not 

 remain constant, but agreeing with the variations of the nor- 

 mal temperature, is lower in the morning than toward even-

Recording of the variations in temperature which occur 

 during the course of a disease is also of great importance. 

 If the temperature is measured at a certain time daily and 

 the record expressed in a graphic manner, the so-called fever 

 curve is obtained. From the fever curve is recognized the 

 type of fever present. 



In veterinary medicine the following types of fever are 

 important : 



1. Continued fever, dailv variation less than 1° C. 

 (1.8° F.). 



2. Rcn-ittoit fever, dailv variation over 1° C.
