Study of Normal Maximal Temperatures. — Concluded. 



From the above table, the normal maximal temperatures, it will be 

 noted, range in variation from a fraction of a degree to over five degrees. 

 These temperatures, it is true, cover a period of two years; yet some of 

 the greatest variations are found occurring during two successive days. 

 This may be noted in the cases of Nos. 5 and 17 and in a less marked 

 degree in Nos. 20, 39, 53, 09, 105. 114 and others. Owing to this great 

 variation in normal maxima] temperatures we feel justified in bidding 

 caution to all operators in the tuberculin test. The too prevalent method 

 of finding the maximal temperatures of the day of and the day after 

 injection and condemning animals in accordance with this standard with-
