Galvani introduced the nerve of a rheoscopic leg into an open circuit, and allowed the nerve of another leg, completely isolated from the first, to fall upon the circuit, in such a way that the cross-section of the first nerve formed one of the two points of contact. Both legs twitch in a successful experi- ment. Du Bois-Reymond laid the central end (transverse and longitudinal sections) of a sciatic nerve, still connected with the leg, acro

Both legs twitch in a successful experi- ment. Du Bois-Reymond laid the central end (transverse and longitudinal sections) of a sciatic nerve, still connected with the leg, across the pads of his zinc trough-electrodes, making and breaking the nerve current by means of a mercury key. " The leg twitched at closure and at opening, in some cases on breaking the circuit ; Du Bois-Reymond subsequently simplified this experi- ment by placing two long pads of filter-paper saturated witli salt solution close together upon an insulating stage, and laying acr< iss them the long and transverse sections of the rheoscopic nerve.
