CONTAGIOUS PLEURO-PNEUMONIA.

changes have taken place in the lung, proving that the disease 
has been gradually increasing for some time before its presence 
in the system was made manifest. 
“In examining a suspected herd of animals, all showing a tem¬ 
perature above 102° should be carefully [watched. If the 
heat rises above this, there can be little doubt that disease is at 
work. When the disease is established, the temperature may 
rise to 105°, 106°, and rarely to 107°. In 134 cases recorded, 
eight readied this temperature.”— Williams. 
“The obvious symptoms are slight rigors, the hair standing 
the wrong way, loss of appetite, diminished secretion of milk, 
nuckling over of the hind fetlocks, cough, apparently full belly, 
constipation, scanty and high-colored urine, pulse sometimes large 
and soft, at others accelerated and feeble in character, and, again, 
small and wiry, tenderness on pressure to the intercostal spaces 
and back. Should recovery not take place, signs of general 
disturbance gradually — sometimes rapidly—rincrease, cough is 
more persistent, mucous membranes of the nose injected, respira¬ 
tory movements are increased in frequency, abdominal and shal¬ 
low, elbows turned out, nose extended, back arched, hind limbs 
drawn under the body, the breathing becomes painful, accompan¬ 
ied by a moan or grunt on expiration, and nostrils dilated. A 
purulent and yellowish discharge sometimes from the eyes and 
nose; the extremities, horns and ears vary in temperature, the 
surface of the body hard and dry, hidebound ; constipation, often 
succeeded at an early stage by diarrhoea.”— Williams. 
To return to the symptomatology of this disease, as seen by 
me in the individual cases, in different parts of this State, and in 
the State of Hew York. I find that the first animal examined 
at Mr. Eaches’ farm had been noticed to be unwell for about ten 
days, at the present time showing a temperature of 103 3-5°, 
labored and shallow respirations—about 50 per minute. I was 
unable to get the pulse at all satisfactory ; there was loss of appe¬ 
tite, urination being suspended, yet the belly had the appearance 
of being distended with food, resembling that condition known as 
lioven : a term applied to cattle when distended with gas from 
eating too much green food. The back very much arched, the 
hair rough and shaggy, the countenance expressive of great anx-
