persistent diarrhea, but generally OBJ
stinate constipation. In some cases
large abraded spots are observed at the
projecting parts OF the body, caused by
separation and loss of the epldermls;
in these cases a slight blow or friction
on the skin is sufficient to produce such
abrasions. In many cases the eruption,
the blush, and spots are entirely absent;
netechie were formed in about one
t .ird of the cases; in n outbreak,
chiefly confined to pigs in which the
eruption was remarkably plain, there
was considerable inflammation of and
discharge from the eyes. Some animals
have a very disagreeable odor even be

weakness or partial paralysis of the pos

paralysis is SO complete in the first
stages of the disease as to prevent walk
ing or standing.
The percentage of animals affected
and the violence of the symptoms vary
greatly, according to the time the dis
ease has existed in a locality. In the
early part of an outbreak from 20 to 90
per cent. die, and most of these in the
first stages of the disease, from deterio-
ration OF the blood or apoplexy. In
