iety, indisposition to move, occasional cough, pressure on the 
hack and intercostal spaces causing considerable pain, the hind 
feet drawn up to within a few inches of the fore ones in order to 
make them carry as much weight as possible, and in this way 
relieve pressure on the chest walls; the nose and mouth hot and 
dry, the feces hard and dry and in small quantity. No special 
note could be made of the urine at this stage of the examination; 
mucous membrane of the eyes pale and livid, and of the nose 
congested. 
Percussion of chest walls on left side gave exaggerated or 
tympanitic resonance in its entirety, the respiratory murmur 
much increased, loud and harsh, giving the impression of disease. 
In fact this mistake is often made; it is one of the errors of diag¬ 
nosis, and must be guarded against. 
Percussion on the right side gave dullness over the whole ex¬ 
tent of the lung, and caused considerable pain; on auscultation no 
sound was audible in any portion of the organ. 
After completing my examination the animal was slaughtered ; 
the tissues covering the chest wall on the right side, including the . 
fore limb, were next removed, and the thoracic cavity opened. 
The first thing to attract attention was the large quantity of fluid 
contained therein, yellowish in color, and floating in it were 
lumps and shreds of friable fibrous material, breaking down 
easily under the finger. I judged the quantity of this fluid to be 
about eight pints. When tested, was found to contain albumen ; 
it coagulated into a firm clot on exposure, to the air, but would 
again liquify when the temperature was raised to 100°, or about 
that of the body. 
On removing the right lung from the body, it was found to 
bo consolidated and hepatized throughout its entire structure; 
the surface or pleura of the organ was covered by a fibrous or 
croupous exudate, in many places half an inch thick, which could 
be easily removed, leaving the pleura as if covered by granula¬ 
tion. When thus removed, blebs or bulla were observed just 
under the pleura, varying from a pea to an egg in size. These 
bulla were filled with a material which in every respect resembled 
that filling the chest cavity. There was no way of determining 
the exact weight of this organ; it was roughly guessed at from
