A wave is represented at the moment when it has just crossed each ot the clips. ment 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. Fig1. 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.
