kresol was added as in the above experiment. In eight days 
one of the bulls and one of the heifers refused their food, be¬ 
came gaunt, showed reeling gait, which continued for some 
days. They were eating again reasonably well by the expira¬ 
tion of two weeks. The other bull and other heifer which re¬ 
ceived the same dose at the same time were not apparently af¬ 
fected. 
After twenty days the four were re-inoculated as in the first 
instance. The two that were sickened by the first dose were not 
apparently affected by the second. The other two, on the ninth 
day refused to eat, and were stupid for several days. On April 
25th, each animal received a third inoculation of 8 cc., of de- 
fibrjnated blood, but no effects were apparent from it. 
Lot II, consisted of six registered Shorthorns, raised in 
Cooper county, Missouri, bred by W. P. Harned. They were

shipped to Collin county, Texas, where they arrived April 21st, 
1898. The lot consisted of one bull seven months old, and five 
heifers from 8 to 12 months old. On April 25th, each one re¬ 
ceived 4 cc. of defibrinated blood subcutaneously. This blood, 
as in the former experiment, had been prepared at the Texas 
Experiment Station, from an immune cow. Eight days later 
four of the calves left their feed untouched, but no symptoms 
of an alarming character developed.
