PLEUROPNEUMONIA

was sufficient evideuce that pleurisy bad existed, but uo evideuce of diseased 
lungs, one of which had been carried away. As the symptoms of the two that 
were ill were not sufficiently positive, it was decided to isolate the herd, and 
await further developments. 
On the 8tli of March another visit was made, (a request having been re¬ 
ceived) wheu two more of the herd were found sick, one of which had the 
night previous aborted a calf. 
One of the first alluded to was selected, (percussion giving a flat sound over 
the whole thoracic region of the right side) and slaughtered. 
The autopsy showed adhesiou of the whole of the large lobe to the ribs, 
which was evidently of loug standing, probably a year or more; several phy¬ 
sicians being present, all were of this opinion. 
Ou cutting through the lung, unmistakable evidence of contagious pleuro 
pneumonia was present. 
The isolation of the remainder of the herd was continued, during which 
Mr. Adams fed, with grain, one of the cows which showed but slight symptoms 
of illness, wheu we were present. 
On the 8th of June she was slaughtered, and the examination disclosed ad¬ 
hesion to exist to the sixth and seventh ribs, and to the vertebrsB. A cyst, con¬ 
taining a mass weighing, by estimate, two pounds, was found in the lung. As 
no other cases had occurred from the 8th of March to the 8th of June, the herd 
was released. 
It should be noted that Mr. Adams’ herd consisted of five cows, which had 
been kept on his own farm during the season, a yoke of oxen, four two-year-old 
heifers, and three cows which he had kept in at pasture in Ashburnham. The 
, first animal taken sick was one of the heifers he brought from Ashburnham 
about the middle of August, and was taken sick about the 20th of December. 
The Commissioners were unable to find that pleuro-pueumonia had ever ex¬ 
isted in any herd withiu six miles of Mr. Adams’ farm. 
Our attention was next called to the herd of Avery Whiting, of West Ded¬ 
ham, consisting of three cows only. The history of this herd is as follows : 
In March, Mr. Whiting purchased the three cows of a dealer ; the one first 
sick came from the north part of Waltham the market day previous to his pur¬ 
chasing them. By the statement of Mr. Whiting she was taken sick about 
April 1st, but according to that of his hired man, after the 21st, and was very 
sick for some time, but gradually recovered her appetite, and on our first visit 
gave seven quarts of milk per day. She was thin of flesh, and gave evideuce of 
having suffered severely. 
On the 13th of June another was taken sick, which died the 3d of July. 
On the 4th an examination was made, which disclosed the right lung wholly 
consolidated, and weighed twenty-six pounds. The thorax contained at least 
three gallons of serum; a thick coat of lymph intervened between the pulmo¬ 
nary and costal pleura. 
On the 22d of the same mouth the third cow was taken sick, and on the 
24th she presented the usual symptoms of pleuro-pueumonia. Both of those 
that survived were kept until the 22d of November, when they were slaughtered ; 
a description of them is given in the report relating to experiments which have 
been conducted during the past year-.
