TUNMANN
In the tradition started by
Raspail almost 100 years earlier, Dr. O. Tunmann wrote a textbook in 1913
devoted to the application of microchemical tests to plant materials [Tunmann
(1913)]. This text (Figure 23) on plant microchemistry contained 137 illustrations
(Figure 24). A second edition updating the text was published in 1922.

MOLISCH
Also in the tradition
started by Raspail and complementing Tunmann’s books on plant microchemistry,
Hans Molisch published several books on plant structure and microchemistry,
including the third edition of his Mikrochemie der Pflanze (1923). The
third edition of this text (Figure 25) contained 135 text figures, including
line drawings (Figure 26), and photomicrographs (Figure 27).
