“…3 B, 3 C, 3 CC), and by a similar wave which passes in the direction above the abscissa and is followed by a downstroke to be followed by a pause in the case of nystagmus to the right (figs. 3 B, 3 C, 3 CC), and by a similar wave which passes in the direction above the abscissa and is followed by a downstroke to be followed by a pause in the case of nystagmus to the right (figs.…”

“…It can therefore be observed that in a person with nystagmus, if the temples on the two sides of his body-essentially bony structures which as depositories of inor¬ ganic salts form an excellent conductor of the electric current-are con¬ nected with the electrocardiograph, allowing the action currents from the contracting muscles of the eyes to be led off through the string galvanom¬ eter, a characteristic record is obtained which shows a distinctive curve *Submitted for publication, Aug. 3,1928. They do this not only in nystagmus to the different poles of the plane but during each cyclic process of the phenomenon, a composite process consisting of a slow movement of the eyes in one direction which is immediately fol¬ lowed by a quick movement in the opposite direction.…”
