...In the course of his time experiments, Helmholtz used the graphical method for illustrating the phenomenon of “lost time”. This chapter describes and investigates the curves that Helmholtz produced by means of his “myograph” in order to illustrate his previous findings. Successive contractions...

...Drawing on Bruno Latour’s notion of “circulating reference,” this chapter shows how the curves that Helmholtz recorded in the context of his time experiments were meant to be integrated into his publications. The first step was to produce imprints of these curves on a flat, transparent, cohesive...

...This chapter describes Helmholtz’s reaction to the difficulties he had encountered in communicating the results of his time experiments. On the one side, he started popularizing his findings in lectures before general audiences and by extending his measurements from frogs to humans. On the other...

...This chapter discusses the semiological and epistemological status of Helmholtz’s curve recordings. It argues that these curves did not provide precision measurements of time but instead illustrated the basic structure of Helmholtz’s time experiments. The parallel traces that Helmholtz obtained...
