On the electrical phemomena of the excitatory process in the heart of the frog and of the tortoise, as investigated photographically.J. Physiol. (Lond.), 4, 327-38, 1883 – 1884.See No. 824. This paper contains several tracings of the heart's electrical activity recorded with a capillary electrometer, the earliest graphic recorder of bioelectric signals. These were the "first undistorted tracings of the electrical activity of the heart" (Burch & Depasquale, A history of electrocardiography, 1990, 102).
