Two and one-half suchwaves occur in the tracings, the one at the right-handside of the figure being cut off. And the same circumstancealso presents in the tissue tracings (V), only that they aresmaller and arrive later, having to pass over the arteries inorder to reach the tissues, the nerves lying u
