The Stethoscope gives a crackling sound in the early stage, followed by increased dullness, and, finally, by crepitating wheezing.
Percussion gives after the first stage a dull return to the finger.
Disease Terminates in resolution, with cessation of the bad symptoms; or in solidification, called hepatization ; or sometimes in abscess of the lung.
Inspiration and expiration both difficult and interrupted. Cough present, but not frequent, and evidently avoided and suppressed. Expectoration rarely profuse; sometimes absent.
Stethoscope indicates hepatization, from the entire absence of murmur.
Percussion also gives a very dull return to the fingers. Sometimes there is a mucous rattle.
Terminates sometimes in resolution; or, if fatal, in a discharge from the nostrils of purulent matter, coloured with blood, and often very fetid. The animal never lies down at length, but sits up on his hind legs.
