Ing in regard to pleuro pnsumonia, the
dreaded cattle seourIe, which has recently
broken out in Chicago and other points, Il
cleaned from the very best authorities on
the subject in America, England. France
and Germany:
The disease is divided into two stases.
In the first stage the blood IL viscid and
thick, in the second dark and fluid. The
first may last from two to six weeks. The
earliest sign 10 given by the Thermometer;
under 100 degrees the cattle may
be considered healthy, above that and
under 100 degrees may b looked

rapid with young and vigorous animals:
Recovery may take place In either stage;
but convalescehce may BIZ rather tar:
dy; running Through months even;
and during all OF which time the animal
may infect othefs: The deaths are
estimated at from 20 to IS per cent. in
mild invasions: In severe epidemics they
range as high as 80 per cent: The average
OF exposed cattle which take the disease in
this country has been estimated at 28 per
cent.
Among the predisposed courses of the
disease are, distilled food tod rapid fatten-
Ing, excessive milking, marshy pastures, cold,
damp. exp osure, hot, damp stables, changes
OF food and OF climate, Overcrowdiug, etc
Authorities differ on the distance which
the injection may be carried through the
air; some say not more than II to Is feet;
Others place it as high az 1000 feet: In
Europe, water courses twenty five feet wide
have been known to stay the plague; tho
limit OF contagion is generally supposed to
be froih So to say 200 feet.
-, The appearances after death are;
the lungs enormously enlarged and
hepatized throughout like liver, nei.
ther the heart nor stomach is much
affected. The flesh is in no way
different in appearance from that OF a
healthy OK, in the same condition az to
lat.
From iii to 1868 this ling pestilence
destroyed 200, 100000 head OF cattle in
Europe. 1t reached Prussia in 1902, Eng
land in S41, where, in 1856 it proved ia
tai to 500, 600 head in eighteen months. 1t
came to Brooklyn in 1S43, New Jersey
in 1914, to Brooklyn again in 1850 and 10
Boston in 1859. Switzerland has been
called the home of pleuro.pneumonia. The
contagion is very subtle; the flesh of dis.
eased animals has conveyed the malady.
Cattle have caught it from grazing in pas.
lures or feeding in stables months after use
ny infected stock: All intelligent au-
thorities concur in saying that on n.y.
gienic grounds there is no reason to in
terdict the sale of such flesh as human
food; but due care should be taken with
regard to the spread of the disease through
the meat to healthy cattle. The flesh OF
millions OF such diseased animals has been
consumed i'll various parts of the world,
yet there has never been case where in
furious consequences have been traced to
its use. And as with the flesh, so with the
milk, which the most enlightened physi.
clans pronounce harmless.
