LEGISLATIVE VISIT TO THE FARM OF Mr.. CHENERY
IN BELMoNT.-Some sixty members of the Legisla-
ture, including the committee who are investipa-
ting the subject, visited the farm of Mr.. Winthrop
Chenery, in Belmont, this forenoon, for the pur-
pose of witnessing autopsy of diseased cattle
They were accompanied by a large number of the
medical fraternity. 1t mainly with the view
of developing the disease in a new and different
aspect from that presented in the incpient and
acute case at Brookiield, that the examination of
the subjects in this herd was made. Upon the ar
rival OF the Commissioners yearing calf was Sc
lected from number of Others as a fit subject ia
Illustrate the effects of the disease in cases where
the animal had been sick, and to all eyternaI an
pearances has recovered. The calf was taken sick
in October last, and for four or five weeks was so
i'll as to take no other nourishment than pruaI
poured down its throat During the Last fbree
months the creature has gradually regained its an
petite and consequently its strength and was SIM
posed TO De recovering Still it coughed. and upon
percussion exhibited dulness on the rirht side and
strong tubular respiration The necessary nrena
rauons having been made Mr. Commissioner To-
throp introduced DR.. Martin who stated in brief
his diagnosis of the case He expected to find the
most disease in the right lung, and no donbt adhe
sions. The calf was killed. the right shoulder and
ribs removed, and the chest laid open by Drs Dadd
aud Thayer. There was strong adhesion of the
pleura of the lung to the ribs, diaphram and heart
case The lung indicated that it had been compress
ed into small compass, by serum which had in the
subsequent progress of the disease been alb
sorbed. The wndpipe contain ed a secre-
ton of mucus, which probably produced
the rafting heard before death the mem
brane Of the lung was very much thickened
and the lung tissue nearly destroyed. The cyst or
bag OF the lung was found empty whereas in cases
OF the disease in an acute form it has been found
to contain large body or lung tissue or the SUBJ
stance of the lung. The theory of those most ia.
miliar with the prevailing disease is that the tissue
in this case had been softened, and reduced to a
liquid state or pus, and then taken up by absorb
ton. The left lung found to be perfectly free
from the disease. The was not fair sample
OF the disease, but it nevertheless demonstrated
the theory of the commissioners that cattle once
SICK will never fully recover. The next animal
Killed was COW, which was brought into Mr..
Chenery,s herd in December last. She had never
exhibited any signs of disease beyond a slight
cough, and an external examination before death
failed to discover any Indications AS the animal
had been exposed to the infected herd, it was a
matter of curiosity to ascertain whether she had
taken the disease. Upon careful dissection of
the lungs the disease found to exist in an Incl
plent stage The heart was soft and fiabby, as in
all cases of this kind and there were other indica
tons of the prevailing contagon. This closed the
investigation. The committee and medical men
seemed to be divided in opinion to the nature of
the disease and the best means of eradicatng it,
There was strong disposition on the part of many
to establish theory of their own and several gen
tlemen did not hesitate to condemn the course
