TEXAS FEVER. 
169 
Before inoculating the bulls, they were given a week’s rest, to 
allow them to overcome the soreness and fatigue incident to 
shipment, and to adjust themselves to changes of food and sur¬ 
roundings. 
On November 7th, fourteen head of the small and medium 
size bulls were inoculated, each receiving subcutaneously 2.5 cc. 
defibrinated blood from an immune Texas steer.* This lot of 
bulls, is designated in the temperature tables and clinical notes 
as “ Group I,” and consisted of animals numbered as follows : 
Nos. 1, 3, 2, 13, 7, 14, 17, 12, 19, 15, 26, 4, 21 and 18. Bulls 
Nos. 4, 21 and 18 were reinoculated Dec. 8th with 2.5 cc. of de¬ 
fibrinated blood from a “ recovered ” native. 
On Nov. 15th ten head more were inoculated from the 
Texan steer, 2.5 cc. blood being given. In this lot was included 
one of the larger bulls (No. 23) weighing 680 lbs. In the tem¬ 
perature table and clinical notes this lot appears as Group II. 
The lot comprises bulls Nos. 8, 22, 20, 23, 24, 16, 10, 28, 25 
and 5. All these except the first four were reinoculated Dec. 
• 8th, dose 2.5 cc., from the recovered native. 
The remaining six bulls, Nos. 58, 11, 29, 9, 30 and 6, the 
largest ones of the shipment, designated as Group III, were in¬ 
oculated Nov. 29th, an initial dose of 1 cc. being given from 
the Texan steer, and nine days later (Dec. 8th) a second inocu¬ 
lation of 2 cc. from the recovered native was given. No re¬ 
action had appeared in this lot up to the time of the 
reinoculation. 
Most of the bulls that were reinoculated in Groups I and II 
had shown no marked fever from the first inoculation, although 
a few animals that had shown fever were reinoculated to deter¬ 
mine the effect of a second inoculation. 
Temperature records and clinical notes are given upon each 
animal of this lot, to supply fuller knowledge of the effects of 
inoculation upon cattle of different sizes, than is available in the 
* This supply animal was received from College Station, Texas, in June, 1898 ; was 
one left over from “ Dipping Experiments.” The animal was kept on an infected pas¬ 
ture during the summer and was bearing a few mature ticks at the time the blood was 
used.
