(Universalkontakt-Apparat (Grosser Zeitsinn-Apparat) nach
Meumann.)
Description: This is Meumann's improvement of Wundt's time-sense
(Zeitsinn) apparatus. It is supposedly shown with a motor to
drive it. It is essentially a large flat disk, running on a low-
friction (brass) cone. The purpose is to allow precise placement
of switches to permit precise timing based on the rotation of
this 28 cm (11 in) diameter wheel. There was apparently a good
deal of controversy about how precise this could be made to be,
since Schumann's Habilitation was a critique of Wundt's
apparatus. Three Contact Pre-selectors (Kontakt-Vorrichtung) are
shown in the inset. (Expanded caption Copyright 1998, Edward J.
