STUDY OF NORMAL MAXIMAL TEMPERATURES. 



The term normal in this connection refers to those temperatures taken 

 previous to the injection of tuberculin and those which are so designated 

 in the tables. Every condition was observed to maintain the usual envi- 

 ronments and circumstances to which the cattle were accustomed every 

 day prior to the taking of temperatures. So far as it was possible every 

 feature was removed which would preclude errors in the obtaining of nor- 

 mal records upon which we could base our reasons for condemnation. 



In a study of the normal maximal temperature, which is so frequently 

 the guide in the condemnation of animals, it is our purpose to show 

 primarily the extent of variation which may take place even when the 

 highest limit of temperature is taken only. The table that follows will 

 fairly illustrate this point because it is a simple record of the normal 

 maximal temperatures and the time when they occurred.
