This was the case in the experiment of which Fig. 2 is a record, no response having been given to the first two shocks. With regard to this interesting stali'case action, two questions naturally present themselves. In the first place, we are anxious to know whether the arousing effect which is so conspicuous in a stair- case series is due to the occurrence of the previous sthnidationd, or to that of previous contractions; and, in the next place, we should like to know whether, during the natural rhythm of the tissue, each contraction exerts a beneficial influence on its successor, analogous to that which occurs in the case of contractions which are due to artificial stimuli.
