tion he became very sliigjjjish, lost his appetite and de- 

 creased about 20 lbs. in weight. This calf was weak and 

 unthrifty when inoculated, and had days of dunipish- 

 ness and loss of appetite durini^ the entire winter. AVhile 

 the reaction to the inoculation was well marked for only 

 one period, yet he seemed to be affected more by the 

 fever than any of the other five animals that were inocu- 

 lated at the same time. During the summer of 1900 

 and of 1901 he became infested with ticks at different 

 times, and for a short time in August had a period of 

 high fever, going as high as 107 one evening (see Table 

 II). Thereafter he made rapid gains, and on August 

 10, 1901, he weighed 1200 lbs. His growth during the 

 second summer has been very good. 



Sixth Gazelle of Maple Hill (See Table I), a short- 

 horn heifer, bred in Missouri, arrived in Alabama No- 

 vember 8, 1899, at the age of 11 months, weighing 692 

 lbs. Was first inoculated December 26 with 1 cc of de- 

 fibrinated blood. The primary inoculation fever began 

 January 7, (12 days after inoculation), and ' >ntinued 

 until January 26 (19 days). The secondary inocula- 

 tion fever appeared about January 31; it was very mild 

 and not distinctly marked. On February 21, this heifer 

 received a second inoculation of \\ cc of defibrinated 

 blood, but no distinct fever reaction followed this inocu- 

 lation. She lost her appetite one or two days, and had 

 one day of short and rapid respirations during the pri- 

 marv fever of the first inoculation. February 16 and 

 22 a very few ticks were found on her. June 16 several 

 ticks were found on her, having been in tick-infested 

 pasture since April. July 16 she appeared dull and 

 stupid, and July 24 her temperature rose a little above 

 the normal ; no doubt she had, at this time, a very mild 

 attack of fever. She passed through the first summer
