CLINICAL RECORDS OF THE ANIMALS INOCULATED 



WITH DEFIBRINATED BLOOD. 



All of tiie cattle that were inoculated at Auburn were 

 stabled at ni^lit, carefully handled during the entire 

 I>eriod of inoculation. The ticks were kept off by weekly 

 applications of kerosene oil emulsion. Neither cotton 

 seed nor any of its products were fed them during the 

 inoculation periods. Unless otherwise mentioned, the 

 blood used in the inoculations was derived from a two- 

 year-old Southern-bred Jersey heifer, which had been 

 infested with ticks during its second summer, and had 

 been tested for tuberculosis. 



1. Admiral (see Table I), a red poll bull, bred in 

 Illinois, arrived in Alabama Nov. 11, 1899, at the age 

 of ten months, weighing 742 lbs. December 26, 1899, 

 was inoculated with 1 cc of defibrinated blood. Very 

 little, if any, primary inoculation fever occurred; but a 

 fairly good secondary inoculation fever began January 

 25, 1900 (30 days after the inoculation), and continued 

 until February 4. He was inoculated a second time 

 February 21, 1900, with IJ cc of defibrinated blood. A 

 very slight rise of temperature appeared on February 26 

 and 27, March 3 and 4, and March 22. The inoculation 

 fever periods in this animal Avere all more or less ir- 

 regular, very slight or absent, excepting the secondary 

 inoculation fever following the first inoculation. Dur- 

 ing the entire inoculation periods he exhibited no signs 

 of ill health. Ticks first appeared upon him June 16. 

 July 21 he was very much depressed or dumpish. August 

 10 he began to breathe rapid and shallow ; morning tem- 

 perature 107, and at noon 108 degrees Fah., remaining 

 at about 106 for the next four days ; then it dropped to 

 normal for two days, rising to 107.4 on August 19. Hig
