The clay moulds itself firmly to the shape of the muscle, holding it sufficiently by contact alone, with no perceptible pressure, to prevent a direct transfer of the changes of form from one half of the muscle to the other, without inhibiting the transmission of the excitatory process. The non- polarisable electrodes make it possible to continue the passage
