The junction of the tail with the trunk is to the left of the figure; n indicates the notochord. These considerations leave little doubt that the skin impulses of Oikoplcnra are propagated across the epithelial cell sheet which forms the outer surface of the animal. The wave forms recorded with suction electrodes show considerable variation. In their simplest form, skin impulses are smooth biphasic events, but secondary blips, shoulders and composite wave forms are also seen. It must be borne in mind that suction electrodes vary in bore and resistance; in the amount of tissue they cover or imbibe (partly dependent upon the suction applied) ; in the extent to which they damage the cells under or around the point of attachment;.
