  • Hi -- It appears the link for the color sense tester goes to the wrong reference page, as that piece of equipment does not appear on the page. (p. 0017, fig. 12321). Can this be corrected and if so, can you let me know when it is available? Thank you -- [mail address removed]

  • I first used this laboratory notebook in the 1990s when I authored a paper with Frederic L. Holmes entitled "Experiment, Quantification, Discovery" in a volume edited by David Cahan. It started quite a flurry of interest in the propagation velocity of the nerve impulse. Thank you for making parts of the Helmholtz Nachlass available to scholars.
