G. 7. —Disposition of a bundle of muscle between two pairs of myo- graphical clips. Clip No. 1 holds the electric excitators of the muscle. A wave is represented at the moment when it has just crossed each of the clips. menfc compresses a sort of little drum which sends a portion of the air which it contained through an india-rubber tube into a similar little drum. Fig. 7 shows two of these instru- ments fixed upon a foot. The expansion of the membrane lifts a registering lever, and thus gives notice of the dilatation of the muscle at the point where it is compressed by clip No. 1. The movement is shown upon the tracing by a curve analogous to those which we have already Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marey, Etienne-Jules, 1830-1904.
