CONTRIBUTIONS TO THE PATHOLOGIC AND 
time ; the remaining periods she was comparatively easy* At 
present no great improvement is visible. The medicine to be re- 
peated in two hours, with the addition of spts. of nitre §ij ; then 
to be repeated again at two o’clock A.M. ; to have also some chilled 
water or thin gruel given to her; the udder to be stripped as 
usual, and the cow occasionally turned over, and her limbs well 
hand-rubbed. 
Ylth. Eight o'clock , A.M. — Upon arriving at the residence of 
the owner of the cow, I was very much surprised to learn that the 
animal had died about three o’clock this morning. I was told that 
shortly after two o’clock she was attacked with a relapse ; that 
those in attendance upon her left the cow for a short time, for the 
purpose of obtaining some refreshment, and that upon entering the 
place again they found that she had died. 
Examination eight hours after Death. Digestive Organs. — A 
large quantity of gas escaped when the intestines were cut open, 
but the digestive organs themselves were in a very sound state 
throughout; the food which they contained was soft or pultaceous, 
generally ; the paunch was moderately filled, and the maniplus 
also ; some portions of the food in the latter organ were drier than 
others ; the drier portions were principally in connexion with the 
central folds of the organ. 
Organs of the Chest. — Upon opening the chest, it was at once 
apparent that the lungs were very extensively diseased, for nearly 
every part of these important organs was tuberculated. I cut away 
two masses of lung, each the size of a brick, and almost as hard 
from the accumulated presence of dry tuberculous matter. The 
matter itself was of a brightish yellow colour, and very closely re- 
sembled decayed cheese ; it emitted scarcely any odour ; some 
portions were extremely soft, others hard, dry, and somewhat chalky. 
It was also impacted in masses, each mass being contained in a 
kind of cavity, and these cavities, many of them, communicated 
one with another. Those portions of the lungs free from the tuber- 
culous deposits were intensely congested with black blood. The 
pleura was healthy ; the heart was small in size, and its substance 
did not present any strong degree of tonicity ; all its cavities were 
filled with black blood in a semi-coagulated state. 
Nervous System. — The membranes investing the brain were 
moderately firm, but considerably congested. A quantity of serum 
existed at the base of the brain, immediately under and around the 
base or roots of the optic nerves; the substance of the brain was 
moderately firm, but the colour of the cortical and medullary por- 
tions was not so clear as I have seen in other specimens. The 
spinal cord I examined throughout its whole length, and its invest- 
ing membranes were similarly congested to those of the brain; the
