available had throughout advanced into a state of firm, dry, 
granular hepatization and had a mawkish, heavy odor, and no 
thermometer could be found marking above I20 p F.; as a re¬ 
sult the heat employed failed to sterilize, and the tails 
swelled as under an inoculation with the unaltered virus. The 
* 
result was protective, but many lost their tails, and one 
Jersey died in a herd of fifty head. 
Most of these cases were reported to the Fourth Inter¬ 
national Veterinary Congress at Brussels in September, 1883.

EXPERIMENTS WITH ANTHRAX. 
N. O. Shepherd, Skaneatles, N. Y., had nineteen head of 
cattle attacked with splenic apoplex}^ January, 1883. In a 
few day he lost seven adult cattle and one calf, together with 
a mare and colt and one pig. Eleven cattle recovered. In 
March, 1884, he lost one heifer, in May three young calves, 
in June one mare, July 3d one horse and July 6th one year¬ 
ling colt. The cattle first attacked grazed in a pasture in 
which was a swamp and where there had formerly been a 
slaughter house. The horses in 1884 were kept in an orchard 
into which drained the yard used by the infected cattle in 
1883. 
July 8th I visited the herd, obtained the requisite blood 
from a victim of the disease, heated it for an hour to 150° F. 
and injected twelve cattle with one drachm each of the 
sterilized product. One heifer remained, and by desire of 
the owner this was left as a test case. Within two days the 
thirteenth animal died of anthrax and the other twelve sur¬ 
vived without illness. 
In 1885 I operated in the same way on a large herd of 
cattle in Columbia County, N. Y., among which anthrax had 
appeared. This herd escaped without a single loss. 
From the early eruption of symptoms and the rapid prog¬ 
ress of anthrax it is especially favorable to such treatment 
in infected herds. The truly sick can easil) 7 be picked out, 
and the inoculation of the others is likely to prove protective. 
The shortness of the incubation, and, above all, the absence of
