PLEURO-PUEMoNIA BY INCUBATION.

TTT
England. Two reports thereon, by the Dutch
Commission, were published in 1852 The
detail of the experiments touching incubation
are accurately given. We have room only for
the results
lst incubation is not a harmless operation.
ID. Precaution in regard to matter, the time
of operation, the season, condition and the state
OF the health of the animal must be consld-
cred Other conditions are named, but must
be passed by The conclusion reached, Is,
that incubation is tavoraby regarded by the
Commission; also, that the danger Of the rem
edy by incubation is in no proportion to the
losses by the natural disease.
The Belgian report, very able document,
furnishes the following conclusions That in
uculation with the matter taken from IL hepa
tizcd lung, the result OF eXudatlve pieuro-
pneumonia, is not certain preventive of the
maady. That incubation may be produced
several times in the same ANIMAL which may
or may not have been attacked by eXudative
1pleuro-pneumonia. That the two affections
may exist together in the same animal, and
that considerable arrangements are manifested
In the inoculated part, while the morbid action
OF the lungs progresses towards fatal termina-
ton. As to the ascertaning whether in0cula.
ton really possesses a preventive power, and
if so, in what proportion and for what length
of time, these are questions that must be
solved by further experience. Thus on the
Continent the ques ion of the usefulness of in
oculation is disputed one.
In order to afford Prof. Simonds an oppor-
tunity to make experiments, a number OF ami
mails were placed at his disposal by Mr.. Paget
of Ruddington Grange, near Nottingham
PIeuro pneumonia having prevailed in that
neghborhood since 1913, first showed itself on
Mr.. P's farm in August, 1S49, and, down to
Christmas, carried off 70 animals. In 1851 he
lost 80; and from January, 1852 to the end of
November, when the experiments were COM
menced, 30 more had died. making total loss
from 1849 to 1852, of 1872 animals. 1t should
be stated that his animals werewolf fed, and so
soon as one showed signs of disease it was
killed-eXperience having shown the general
inutility of medical treatment. The rate Of
the progress of the disease has not been uni
form. The appearance of the epizootic ecze-
ma among his COWS in August, 1852, rem
dered his cattle more susceptible to the pleuro-
pneumonia.
tits a fact of interest that two bulls which
had been exposed for two years were in per-
feet health at the time of Prof. SIS visit. Cow
after COW that fell victims to the malady had
been tied contiguous to the bulls. The causes
of the disease and its fatality are a mystery.
The animals were literally fed in well-ventila-
ted sheds His herd consisted mostly of mid
die aged shorthorns. This was the condition
of FACETS herd, where fruitess efforts had
been made to arrest the malady prior to the
introduction of incubation.
On the 9th of November sixteen animals
were selected for the operation; of these
twelve were in0culated on the under surface
of the tail, near its extremity, by superficial
punctures, and four by deep punctures after
the manner OF DIR. Willems. The material
used in the incubation was the Serious fluid
from a diseased lung, two or three drops being
applied. Care was taken to have it fresh, and
not from lung 'over-dseased." Fourteen of
these inoculated cows were left to mingle with
the herd, and two were kept in an intirmary
shed, where diseased animals were kept in or
der that they might be exposed to contagion
This was continued several weeks, the animals
the meanwhile remaining unaffected.
With two exceptions the incubation did not
produce the slightest effect and in these not
till the fifteenth day. On the 18th of Decem-
Der twelve of them were re-inOculated, the 9th
er two being suffered to remain, in order to
watch further the results of the first inocua
ton, DR.. Willems having stated that it was Il
month sometimes before the local effect was
observed. But no such result followed, and as
one of these cows had been a little out of
health for almost week, it was determined
not to repeat the operation on her. This COW
continued as free from the disease as the inocu-
lated The other was inoculated and lost her
tail from inflammation attending the operation.
The re.inoculationS were from matter obtained
from lung in a more advanced stage of the
pleurO-pneumonia. Seven of the fourteen
0ases were renoculated, and the operation
was successful in four cases. Seven animals
died Of the disease on the farm in December,
six non inoculated and one inoculated. The
latter was, it is thought affected with the pleu-
ro-pneumonia in its incubativc stage when in.

not modify the disease, taken the natural way
facts totally at variance with the laws of in
ocuati0n for disease.
Fourteen more were inOculated on the 29th
of December, and considerable effect was pro-
duced on six, very little on four, and none at
all on the remaining four. NEGOTIATIONS were
continued till the end of February, when near
ly all the herd had been inoculated, amounting
TO about one hundred. Three animals died in
January, one Of them un inoculated, and one
inoculated, the latter on the day preceding her
illness. In February, four died, two inocula,
ted and two were not. In March yearling
bull died In April none died, but in May
three died, all mOcuated Five cows resisted
the incubation, which was performed several
times. Eight COWS lost their tails. The
young bull Just alluded to died of incubation
on the twenty first day after incubation.
Professor Simonds arranged on his first visit
to Ruddington in November, to have six cows
sent to London, to be experimental on at the
college. After allowing sufficient time for
their recovery from fatigue of the journey,
three of them were inoculaIed. No effects fol-
lowed. The operation repeated at an in
terval of eight DAYS. This also failed. 1t was
repeated and failed again. One of the cows
suspected of having the pleuro-pneumonia in
cubated in her system, from her peculiar
cough and other symptoms, died on the day
succeeding the innoculation She lived
twelve days after the attack, and then died
The post norton examination showed the dis
ease. January 9th the five cows were again
inoculated. Nothing took glace. On the 18th
it was repeated; no effect; so again on the
10th, proving abortve. These were all
slight punctures.
Jan 2Sth-Inocuated three cows with deep.
or punctures. Feb 1st-A slight tumefaction
in one case. 2d-A small pustule has formed /;
scab over the wound. 3d-SuppuratiOn in all
three cases. Re-inoculated the same cows.
4th-Pus discharged from the original wounds.
5th-Swclling around the second inclsions.
7th-Pus discharging. Sth-The second made
wounds less swelled. 10th-Ihe third inocu-
lated wounds infamed. 12th-The wounds
have a more unhealthy appearance. 18th
Slight liberation going on. 15th-The Incl
sions are heathful and healing.
Still making these cows the subject of ex-
pertinent, they were inocuated again with
fluid from the lung, with deep punctures.
This was done, and the wounds c0mported
themselves rs before. Two sheep were moe
ulatcd were similar results The two cows,
mentioned Jan. Goth, and let alone since, were
now inocuated with roughly made punctures,
after the manner Of Dir. Wiems. The wounds
suppurated and soon healed. They were in
oculated the second time, in one case with the
