CLINICAL DIAGNOSTICS. 



whether fever be present or not. In doubtful cases we speak 

 of high normal temperature. 



The following temperatures may be safely assumed to 

 indicate fever : 



In the horse a temperature of 39.0° [102.2° F.] and over. 

 In the ox " 40.0° [104.9° F.] 



In the dog " 39.2° [102.5° F.] 



In the ox and dog fever is often present without a rise 

 of temperature. In such cases we must depend upon the sur- 

 face temperature and the other symptoms of fever present. 

 Generally the height of the temperature expresses the

height of the fever. Four degrees of fever are distinguished, 

 which for the horse and dog are as follows : 



1. Mild fever 38.5°— 39.5° C. [101.3°— 103.1° F.]. 



2. Moderate fever 39.5°— 40.5° C. [103.1° 104.9° F.]. 



3. High fever 40.5° — 41.5° C. [104.9°— 106.7° F.]. 



4. Very high fever or hyperpyretic temperature 

 41.5° C. [106.-;° F.l and over. 



Usually in the horse even in the most severe infectious 

 diseases, the temperature does not exceed 41. 7" C. [107.0°
