In order to explain thoroughly the function of the appa- ratus, let us reduce it in the first place to its essential elements. Fig. 2 shows a muscle of the calf of a frog's leg, m, suspended by a clip by means of the bone to which the upper part of the muscle is attached. The tendon, t, of the muscle has been cut and then tied by a thread to the lever, L, one end of which can be raised or lowered while the other is fixed ; the nerve, n, is susceptible of electric excitement, which produces certain contractions followed by relaxations in the muscle, that is to say shocks. Each of these movements of the muscle is communicated to the lever, which is raised or lowered, ampli- * Lu Mouvement dans les Fonctions de la Vie, Paris, 1867 : G.
