| A Clinostat as Invented by J. v. SACHS. A clockwork (at the right side of the picture) has weights and a pendulum that start a slow movement of the axis. A mounting is fixed at the axis inside a protecting case (dark chamber), upon which a fungus is growing (Phycomycetes). The middle part of the axis is enclosed by a glass case that is standing upon a water-filled dish that helps to keep the air in the surrounding of the test object humid (J. v. SACHS, 1887). |
