PLEURo PNEUMONIA CONTA.
GIOSA.

GIOSA.
This disease is peculiar to cattle, and
Il highly contagious, having an incu-
bative period of from six days to three
months, at the end of which, local com.
plications arise in the form of extensive
infammatory exudations within the
substance of the lungs and upon the
surfaces of the pleurs, finally resulting
in consolidation of ONO portion of the
lungs and adhesion of the pleural sur
face. There is rapid and extensive
destruction OF lung tissue, with death
from suffocation; but most commonly
the disease is Of a lingering character,
Iymptoms of great p%rostration mani
testing themselves, with blood poison
ug from ABSORPTION of the pulmonary
exudates and death from marasmus
and apuora. Remedial agents of all
kinds have been applied to arrest this
5courge and failed. Eminent patholo-
ylsts have devoted much time to its CON
siieration and have found that inocu-
| ,tion limits the mortality only, but
1 every country where they have been
obliged to resort to incubation the
the disease still prevails. In this country
where only a small area is infected
which threatens 40, 900, 900 head of cat
lie there is only one remedy. Stamp
odt the disease.
HISTORY.
AS in the case of genuine plaques,
mall pox, cholera, rinderpest, a~phtbous
fever, &C., we know nothing Of the
,riginal source of the 'lung fever con-
tagion-we know the disease only as
it is introduced into q country or herd
py a diseased animal or some of its in
tecting products. .Inl ancient as in
modern times, in the old world as in
he new, the malady a ever be traced
N connection with the aggregation of
cattle in herds made up from differ
snt districts and countries. Aristotle
wrote of this disease 800 years before
thirst, although indefinitely, also
Greek and Roman writer's. The modern
history Of the malady may, no wever.
De all summed up 10 this, that when
ever commissariat demands of q large
.rmy led to the aggregation of cattle
from all quarters, and especially from
iteppes of Russia, then this and other
animal plagues have gained a wide ex-
tension. Again the demands of COM
nerce have transported cattle from one
country to another aud thus the con-
Gagion has made its wide spread. BY
an importation of Dutch cattle into
Ireland in 1889 that country became
infected and through their system of
marketing cattle at fairs, the disease
spread over the whole island and it has
prevailed there ever since. England
pecame infected by cattle from Ireland
i 1912. And up to 1869 had lost from
disease ., 549, TS0 head Of cattle
nearly $500, 00O, 600, and for the
succeeding nine years the losses have
been in the main as extensive,
making the total foot up..s5o0, 00o, 900,
in deaths alone notcounting the contin-
gent losses viz; deteriorated health, loss
IF markets, progeny, crops, manure
SC.
Sweden and Denmark became in
tected in 1S47 through an English i'm
portation but they promptly quaran-
tuned all cattle aud those infected were
destroyed. By a thorough system of quar-
of all imported cattle is has since
kept clear of the contagion. Norway
pecame infected in 1860 ; Oldenburg in
1858; Schleswig in 1850
The Cape of Good Hope also in 1854
through the importation of a thorough
bred bull. There the conditions are
to that of the west; the cattle
roam on unfenced ranges and the Rev.
Lindley (who was there at the
time,) testified in 1850 before the
Massachusetts, legislative committee
that the disease WAS still at work when
he came away.
at has killed hundreds and thousands
Of cattle, and l "a assure you gentle
men, that when it has come into Il flock
it has not left more than five out Of n
hundred. With us when an animal is
known to have the disease we look
upon 1t rs already dead. 1 a affirm,
without hesitation, that where it has
got into q herd of cattle not more than
dve out of a hundred have been spared;
occasionally one has passed through
and has not had the disease at all !; and
Il few on the other hand-two or three
in a hundred have recovered, and no
more. 1 know of one mai who had
five hundred head OF cattle, and that
got in and he had not five left.
If L speak with emphasis, it is because
[ have had sad experience; and l have
been afraid that the good citizens of
Massachusetts, might not be aware Of
the evil which l most firmly believe
threatens their property interests more
than anything that ever threatened it
yet"
Australia became infected in 1858
through.an importation from England,
and here again VIC find. a county uu-
fenced where the cattle roam at will.
After the fatal character of the disease
was known, strong efforts were made
to stamp it out; thousands of cattle
were slaughtered, but tho %contagion
had reached the wild cattle on the
plains and was beyond human control.
