Abhandlung über Perkussion und Auskultation.

Skoda classified the various sounds obtained on percussion according to their musical pitch and tone. “Skoda’s resonance” is an important diagnostic sign in pneumonia and pericardial effusion. Following Skoda’s work, percussion at last gained general acceptance as a diagnostic procedure. Digital facsimile of the 1842 second edition from the Internet Archive at this link.
