About this work
A colorful educational chart titled Sputum, labeled as Tafel I, shows a magnified view of sputum with numerous red rod-shaped bacteria scattered among dark nucleated cells and pale fibrous tissue. The printed plate carries a 1912 copyright notice and a 15000-fold magnification note.
