The blood used was drawn from an immune cow in Brazos 
county, Texas. To it was added ten per cent, of saturated 
watery solution of tri-kresol, to lessen the danger of putrefac¬ 
tion. The blood was immediately forwarded to Wichita. The 
inoculations were made by Dr. Ward on November 19, 1897, 
who gave each bull 8 cc. of the blood subcutaneously. After 
inoculation, the bulls were kept as quiet as possible in a lot dur¬ 
ing the day and in a warm barn at night. They were fed 
prairie hay and a mixture of equal parts of corn chop, oats and 
bran. During the fever following the inoculation they showed a 
marked loss of flesh, but none refused food entirely. They were 
held in this lot for 30 days, then shipped to the Brightside 
ranch in Brazoria county, Texas, where they arrived Decem¬ 
ber 24, 1897. They were put with southern cattle, no attempt 
being made to isolate them. They were grazed on oats, and fed 
cotton seed, and sorghum hay. On January 14, 1898, one of 
them died suddenly. One or two others were sick but recov¬ 
ered. No other sickness occurred among them during the fol¬ 
lowing summer (1898), and they have grown fairly well. As 
to the present condition of these cattle, the manager writes : 
“ In the spring of 1899 they were turned in with the range cat¬ 
tle, being at that time two years old. They have taken their 
chances like southern grown cattle, and have done good service 
and look well.”

This experiment differs from the preceding in that the in¬ 
oculations with immune blood were made after the cattle had 
been taken south. 
Dot I, consisted of four animals, two bulls about eight 
months old, and two heifers about 12 months old. These cat¬ 
tle were pure bred Shorthorns, raised near Council Grove, Kan¬ 
sas. They were shipped south and arrived in Collin county, 
Texas, in February, 1898. They received subcutaneous injec¬ 
tions of defibrinated blood, from a cow raised in Brazos county, 
Texas. The bulls received 4 cc., and the heifers 8 cc. Tri-
