the recent disease of the Western States differs from foot and 
mouth disease in the fifteen counts presented in the following 
table, which is submitted as absolutely refuting the statement that 
foot and mouth disease exists in our Western herds: 
PECULIARITIES OF FOOT AND MOUTH DIS¬ 
EASE. 
1st. The foot and mouth disease is 
unknown, except as the result of con¬ 
tagion from a pre-existing case. 
2d. In every invasion of a new coun¬ 
try we can trace the channel of contagion 
from a previously-infected country. 
3d. In a herd of cattle mingling free¬ 
ly in a yard or small pasture every ani¬ 
mal is attacked within a week, and, 
with very few exceptions, all have com¬ 
pletely recovered in three weeks more. 
4th. The escape of a single bovine 
animal in an infected herd is rare. 
5th. Sheep, goats and swine expos¬ 
ed to the infection suffer almost as uni¬ 
versally as cattle. 
6th. Does not attack the tail nor ears. 
7th. Not usually preceded by diar¬ 
rhea, though this may come on later. 
8th. Feet at first affected in the in¬ 
terdigital space only; hoofs never shed 
except as the result of neglect of the 
preliminary inflammation; the bones 
of the feet never lost unless as the result 
of exposure to sand and filth and violent 
inflammation after the shedding of the 
hoofs. 
PECULIARITIES OF TIIE RECENT CATTLE 
DISEA8E IN KANSAS AND ILLINOIS. 
1st. In no single herd can the first 
cases be traced to contagion from with¬ 
out. 
2d. To no single diseased herd in 
either State can we trace any channel of 
contagion from an infected country. 
3d. In the majority of the herds the 
disease has now existed for four months, 
and fresh attacks still occur in cattle that 
have occupied the same yard with the 
sick throughout. 
4th. In some herds half the cattle 
escaped, though mingling freely with 
the sick. In Beard’s, 4 only suffered 
out of 75. After the outbreak at 
O’Toole’s, Kansas, he sold 50 cattle, yet 
they caused no extention of the malady 
among other stock. Hartwig had a 
heifer lost for fourteen days in Prebi¬ 
now’s sick herd, yet it conveyed no dis¬ 
ease to his own on its return. 
5th. Sheep, goats, and swine min¬ 
gled throughout with different diseased 
herds, yet in no case contracted the dis¬ 
ease. 
6tli. Gangrene and sloughing of the 
tail and ears not uncommon. Even 
when the tail seemed to have escaped, a 
close observation often detected a cir¬ 
cumscribed purple slough at the tip. 
7th. Diarrhea a very common pre¬ 
cursor of the disease in the feet. 
8th. When the hoofs are shed, the 
bones are usually detached with them, 
or shortly after, and when the disease 
extends higher up all the tissues (bones, 
sinews, and skin) early dry up and 
wither, up to a given circular line, at 
which point the whole mass is spontan¬ 
eously amputated.
